Science and technology (S&T) play an increasingly important role in our society. Advances in science and technology can help drive economic growth, improve human health, increase agricultural productivity, and meet national priorities. Federal policies affect scientific and technological advancement on several levels. The federal government directly funds research and development (R&D) activities to achieve national goals or support national priorities, such as funding basic life science research through the National Institutes of Health (NIH) or developing new weapons systems in the Department of Defense (DOD). The federal government establishes and maintains the legal and regulatory framework that affects S&T activities in the private sector. Federal tax, trade, intellectual property, regulatory, and education policies can have effects on private sector S&T activity. This report serves as a brief introduction to many of the science and technology policy issues that may come before the 115 th Congress. Each issue section provides background information and outlines selected policy issues that may be considered. Each issue includes a heading entitled "For Further Information" that provides the author's name and the titles of relevant CRS reports containing more detailed policy analysis and information. A table at the end of the report includes each author's contact information. Several issues of potential congressional interest apply to federal science and technology policy in general. This section begins with a brief introduction to the roles each branch of the federal government plays in S&T policymaking, then discusses overall federal funding of research and development. Additional sections address issues related to the America COMPETES Act; oversight of federally supported academic research; technology transfer; the adequacy of the science and engineering workforce; science, technology, engineering, and mathematics (STEM) education; and innovation-related tax policy. The federal S&T policymaking enterprise is composed of an extensive and diverse array of stakeholders in the executive, legislative, and judicial branches. The enterprise fosters, among other things, the advancement of scientific and technical knowledge; STEM education; the application of S&T to achieve economic, national security, and other societal benefits; and the use of S&T to improve federal decisionmaking. Federal responsibilities for S&T policymaking are highly decentralized. In addition to appropriating funding for S&T programs, Congress enacts laws to establish, refine, and eliminate programs, policies, regulations, regulatory agencies, and regulatory processes that rely on S&T data and analysis. However, congressional authorities related to S&T policymaking are diffuse. Many House and Senate committees have jurisdiction over important elements of S&T policy. In addition, there are dozens of informal congressional caucuses in areas of S&T policy such as research and development, specific S&T disciplines, and STEM education. The President formulates annual budgets, policies, and programs for consideration by Congress; issues executive orders and directives; and directs the executive branch departments and agencies responsible for implementing S&T policies and programs. The Office of Science and Technology Policy, in the Executive Office of the President, advises the President and other Administration officials on S&T issues. Executive agency responsibilities for S&T policymaking are also diffuse. Some agencies have broad S&T responsibilities (e.g., the National Science Foundation). Others use S&T to meet a specific federal mission (e.g., defense, energy, health, space). Regulatory agencies have S&T responsibilities in areas such as nuclear energy, food and drug safety, and environmental protection. Federal court cases and decisions often affect U.S. S&T policy. Decisions can have an impact on the development of S&T (e.g., decisions regarding the U.S. patent system); S&T-intensive industries (e.g., the break-up of AT&T in the 1980s); and the admissibility of S&T-related evidence (e.g., DNA evidence).

Federal R&D funding seeks to address a broad range of national interests, including national defense, health, safety, the environment, and energy security; advance knowledge generally; develop the scientific and engineering workforce; and strengthen U.S. innovation and competitiveness. The federal government has played an important role in supporting R&D efforts which have led to scientific breakthroughs and new technologies, from jet aircraft and the Internet to communications satellites and defenses against disease. Between FY2009 and FY2016, federal R&D funding fell from $147.3 billion to $146.1 billion, a reduction of $1.2 billion (0.8% in current dollars, 11.1% in constant dollars); funding has increased from a period low of $130.3 billion in FY2013. The decline was a reversal of sustained growth in federal R&D funding for more than half a century, and has stirred debate about the potential long-term effects on U.S. technological leadership, innovation, competitiveness, economic growth, and job creation. Concerns by some about reductions in federal R&D funding have been exacerbated by increases in the R&D investments of other nations (China, in particular); globalization of R&D and manufacturing activities; and trade deficits in advanced technology products, an area in which the United States previously ran trade surpluses. At the same time, some Members of Congress have expressed concerns about the level of federal funding in light of the current federal fiscal condition. In addition, R&D funding decisions may be affected by differing perspectives on the appropriate role of the federal government in advancing science and technology. As Congress undertakes the appropriations process it faces two overarching issues: (1) the direction in which the federal R&D investment will move in the context of increased pressure on discretionary spending and (2) how available funding will be prioritized and allocated. Low or negative growth in the overall R&D investment may require movement of resources across disciplines, programs, or agencies to address priorities. Congress will play a central role in defining the nation's R&D priorities as it makes decisions with respect to the size and distribution of aggregate, agency, and programmatic R&D funding.

The act, a response to concerns about U.S. competitiveness, authorized certain federal research, education, and innovation-related activities. In 2010, Congress passed the America COMPETES Reauthorization Act of 2010 ( P.L. 111-358 ), extending and modifying certain provisions of the 2007 law, as well as establishing new provisions. Congressional appropriations have generally been below authorized levels, and the specific authorizations of appropriations in the 2010 act have expired. Following previous reauthorization efforts that inspired debate about such topics as the scientific peer review process, certain provisions of these acts were reauthorized and modified as part of the American Innovation and Competitiveness Act (AICA, P.L. 114-329 ), enacted at the end of the 114 th Congress. The 115 th Congress may consider additional provisions from the COMPETES acts that were not addressed through the AICA, such as expired authorizations of appropriations for the National Science Foundation (NSF) and the National Institute of Standards and Technology (NIST). The COMPETES acts were originally enacted to address concerns that the United States could lose its advantage in scientific and technological innovation. Economists have asserted that economic, security, and social benefits accrue preferentially to nations that lead in scientific and technological advancement and commercialization. Some analysts have suggested that historical U.S. leadership in these areas is slipping, and in particular, some stakeholders have questioned the adequacy of federal funding for physical sciences and engineering research and the domestic production of scientists and engineers. The COMPETES acts were designed to respond, in part, to these challenges by authorizing increased funding for the NIST, NSF, and Department of Energy's Office of Science. Together, the acts also authorized certain federal STEM education activities, the Advanced Research Projects Agency-Energy (ARPA-E), and prize competitions at federal agencies, among other provisions. Those who have expressed opposition to aspects of the COMPETES acts have done so from several perspectives. Some critics question the existence of a STEM labor shortage and thus the need for programs aimed at increasing the number of STEM workers. Other critics agree with the assertion of a shortage, but question whether the federal government should address it, believing that the market will make the necessary corrections to meet the demand. With respect to U.S. competitiveness, some analysts prefer alternative approaches to those proposed in the COMPETES acts, such as research tax credits or reducing regulatory costs. Other analysts object to the financial cost associated with the COMPETES acts, given concern about the federal budget deficit and debt.

The federal government is the largest source of academic research and development (R&D) funding in the United States, providing funds through more than two dozen federal agencies, with the National Institutes of Health (NIH) and the National Science Foundation (NSF) providing the largest portions of federal R&D funding to U.S. colleges and universities. As part of oversight of federal funding for academic research, Congress and federal agencies have established requirements through statutes, regulations, and guidance documents that U.S. universities and other research institutions must comply with when applying for, receiving, and reporting on the results of federal research grants. Such requirements seek to ensure transparency and effectiveness of federal funds, while helping to prevent waste, fraud, and abuse. Academic research institutions broadly recognize the need for federal regulations but have raised concerns about unintended consequences, such as reducing research productivity and the return on federal investments. Areas of concern frequently cited by researchers and academic administrators include the amount of time spent completing administrative tasks compared to conducting research; the increasing number, and lack of harmonization, of requirements across federal funding agencies; and the adequacy of stakeholder engagement in the review and modification of federal regulations. Legislation was enacted in the 114 th Congress that addressed some of the concerns, including the 21 st Century Cures Act ( P.L. 114-255 ), the American Innovation and Competitiveness Act (AICA, P.L. 114-329 ), and the National Defense Authorization Act for Fiscal Year 2017 (NDAA, P.L. 114-328 ). Enacted provisions addressed issues at specific agencies, including conflicts of interest disclosure, financial reporting, and subrecipient monitoring. Enacted provisions also addressed cross-agency efforts by directing the establishment of an advisory committee (Research Policy Board) with federal and non-federal stakeholders, as well as an interagency working group on federal research regulations. Congressional oversight may be an important part of monitoring the progress of implementing the provisions enacted in the 114 th Congress in a holistic way and evaluating their overall effectiveness. Further, Congress may broadly consider the appropriate balance between supporting the nation's academic research enterprise through efforts to streamline regulations and maintaining effective mechanisms for oversight, transparency, and accountability. For Further Information [author name scrubbed], Analyst in Science and Technology Policy Marcy Gallo, Analyst in Science and Technology Policy CRS Report R44774, Federally Funded Academic Research Requirements: Background and Issues in Brief , by [author name scrubbed] and [author name scrubbed] Every year, approximately one-third of the federal government's R&D spending is obligated to federal laboratories, including federally funded research and development centers, in support of agency mission requirements. The technology and expertise generated by federal laboratories may have applications beyond the immediate goals or intent of the original R&D. Over the years, Congress has established various mechanisms—primarily through the Stevenson-Wydler Technology Innovation Act of 1980 and subsequent legislation—to facilitate the transfer of technology and research generated from federal laboratories to the private sector where it can be further developed and commercialized. Technology transfer from federal laboratories can occur in many forms. In some instances, it can occur through formal partnerships and joint research activities between federal laboratories and private firms, including through cooperative research and development agreements or CRADAs. In other cases, it can occur when the legal rights to a government-owned patent are licensed to a private firm. Congressional interest in promoting the transfer of technology from federal laboratories is largely based on an interest in meeting social needs and promoting economic growth to enhance the nation's welfare and security. Economic benefits of a technology accrue when a product, process, or service is brought to the marketplace where it can be sold or used to increase productivity. In addition, cooperation with the private sector provides a means for federal scientists and engineers to obtain technical information from the private sector, which in some instances is more advanced than the federal government. Despite the efforts of federal agencies and Congress to increase the effectiveness of technology transfer from federal laboratories to the private sector, the use of federal technologies has remained restrained. Critics argue that working with federal laboratories continues to be difficult and time-consuming. Proponents of current efforts assert that federal laboratories are open to interested parties, but it remains up to the private sector to use them. At issue is whether additional legislative initiatives and federal incentives are needed to encourage increased technology transfer from federal laboratories, or if the available resources are sufficient.

Scientists and engineers are widely believed to be essential to U.S. technological leadership, innovation, manufacturing, and services, and thus vital to U.S. economic strength, national defense, and other societal needs. Congress has enacted many programs to support the education and development of scientists and engineers. Congress has also undertaken broad efforts to improve science, technology, engineering, and math (STEM) skills to prepare a greater number of students to pursue S&E degrees. In addition, some policymakers have sought to increase the number of foreign scientists and engineers working in the United States through changes in visa and immigration policies. Most experts agree that there is no authoritative definition of which occupations comprise the S&E workforce. Rather, the selection of occupations included in any particular analysis of the S&E workforce may vary depending on the objective of the analysis. The policy debate about the adequacy of the U.S. S&E workforce has focused largely on professional-level computer occupations, mathematical occupations, engineers, and physical scientists. Accordingly, much of the analytical focus has been on these occupations. However, some analyses may use a definition that includes some or all of these occupations, as well as life scientists, S&E managers, S&E technicians, social scientists, and related occupations. Among the key indicators used by labor economists to assess occupational labor shortages are employment growth, wage growth, and unemployment rates. Many policymakers, business leaders, academicians, S&E professional society analysts, economists, and others hold differing views with respect to the adequacy of the S&E workforce and related policy issues. These issues include the question of the existence of a shortage of scientists and engineers in the United States, what the nature of any such shortage might be (e.g., too few people with S&E degrees, mismatches between skills and needs), and whether the federal government should undertake policy interventions or rely upon market forces to resolve any shortages in this labor market. For Further Information [author name scrubbed], Specialist in Science and Technology Policy The term "STEM education" refers to teaching and learning in the fields of science, technology, engineering, and mathematics. Policymakers have had an enduring interest in STEM education. Popular opinion generally holds that U.S. students perform poorly in STEM subjects—especially when compared to students in certain foreign education systems—but the data paint a complicated picture. Over time, U.S. students appear to have made gains in some areas but may be perceived as falling behind in others. Previous estimates of the federal STEM education effort found a range of between 105 and 254 STEM education activities at 13 to 15 federal agencies. However, as tracked over time by the Obama Administration, the number of federal STEM education activities appears to have dropped by half, from 254 to 125, between FY2010 and FY2016. While total federal funding for STEM education stayed about the same during this period—close to $3 billion annually—the effects of these changes on the federal STEM education effort overall are unknown. The national conversation about STEM education frequently develops from concerns about the U.S. science and engineering workforce. Some observers assert that the United States faces a shortage of STEM workers; others dispute this claim. Many proponents argue that a general increase in STEM abilities among the U.S. workforce could benefit the nation regardless. On the other hand, some scholars oppose the use of education policy to increase the supply of STEM workers, either because they perceive such policies as overemphasizing the economic outcomes of education at the expense of other values (e.g., personal development or citizenship) or because they perceive the labor market as the more efficient mechanism for dealing with these issues. Opinions differ as well on the appropriate scope, scale, and emphasis of federal STEM education policy. Some observers prefer policies aimed at lifting the STEM achievement of all students—such as teacher or faculty professional development; or changes in curriculum, standards, or pedagogy. Others emphasize policies designed to meet specific needs—such as scholarships for the "best and brightest," federal workforce training, or programs for underrepresented groups. For Further Information [author name scrubbed], Analyst in Education Policy CRS In Focus IF10654, Challenges in Cybersecurity Education and Workforce Development , by [author name scrubbed] The 115 th Congress may consider additional federal policies to promote technological innovation. Among the concerns behind such an interest is what some view as inadequate growth in domestic high-paying jobs in a range of industries in recent years. Four possible pathways to accelerating growth in these jobs are (1) faster rates of entrepreneurial business formation, (2) increased business investment in domestic R&D, (3) greater domestic production of products and services derived from that research, and (4) increased employer spending on training workers to acquire the skills needed to earn higher-paying jobs. One way Congress can influence the rate of high-wage job creation is tax incentives for investment in innovation and worker training and education. Under current federal tax law, three provisions directly affect entrepreneurial business formation and business investment in R&D: (1) an expensing allowance for research expenditures under Section 174 of the tax code (which is scheduled to switch to a five-year amortization for that spending starting in 2022), (2) a non-refundable tax credit for increases in research expenditures above a base amount under Section 41, and (3) a full exclusion for capital gains from the sale or exchange of qualified small business stock held by the original investor for five or more years under Section 1202. There is no federal tax incentive for employer investment in worker training. The tax credit and expensing allowance encourage companies to invest more in qualified research than they otherwise would by lowering the cost of capital for that research and boosting cash flow. Still, some argue that the current credit's incentive effect is too weak to increase business R&D investment to what economists would deem optimal levels. In the view of critics, the credit's design has certain flaws that lead to uneven and arbitrary incentive effects and make it difficult for small startup companies to benefit from the credit in their early years, when they are likely to have net operating losses. The credit was permanently extended at the end of 2015, while the expensing allowance has been a permanent tax provision since 1954. Section 1202 allows a non-corporate investor to exclude 100% of any capital gain on qualified small business stock acquired after September 27, 2010, and held for at least five years. The exclusion is intended to boost equity investment in small startup firms in designated industries (including manufacturing) by reducing the tax burden on the returns to that investment relative to the tax burden on the returns from alternative investments. Recent research indicates that startup firms in business no more than five years account for most net U.S. job growth over time, but that access to financial capital remains a significant barrier to the formation and growth of such firms. It is unclear what share of U.S. high-paying jobs are accounted for by small firms, but small entrepreneurial firms that survive and grow into large, successful companies can be a prolific source of such jobs. Industries that intensively use intellectual property (IP) directly and indirectly (through supply chains) accounted for 30% of U.S. jobs in 2014, and workers in those industries had average weekly earnings that were 46% larger than the average weekly earnings of workers in non-IP intensive industries. The 115 th Congress passed legislation ( P.L. 115-97 ) in late 2017 that substantially cut the tax rates for corporate and non-corporate business income, beginning in 2018. The new law also modified or repealed a number of tax provisions affecting business after-tax profits. Some argue that the tax cuts alone should be sufficient to increase the number of high-paying domestic jobs in a range of industries. Others are skeptical that many large employers will invest the windfall gains from the tax cuts in expanding domestic production and boosting worker wages and training and education. In their view, many large companies (including U.S. multinational corporations) are more likely to use much of the tax savings to buy back stock and raise dividends. One option for increasing the number of high-paying domestic jobs that was not included in P.L. 115-97 but that the 115 th Congress may examine is the creation of a tax incentive known as a patent or innovation box. Such an incentive lowers the tax burden on income earned from the commercial use of qualified intellectual property, such as trademarks or patents. Depending on its design, a patent box could give U.S. and foreign companies investing in innovation a stronger incentive to expand their investment in U.S. R&D and production activities. Potential drawbacks to such a subsidy include its budgetary cost and the difficulty of finding a sound economic justification for a tax subsidy that benefits companies that develop or purchase successful patented innovations only. A second option for spurring faster growth in domestic high-paying jobs that was also excluded from P.L. 115-97 is a tax incentive for employers to invest in worker training and education. Several bills have been introduced in the current Congress to promote employer investment in training programs such as apprenticeships and collaboration with community colleges to design courses of study that are based on the skill needs of employers. The U.S. economy benefits from high-paying jobs only if there are workers to fill them. Potential drawbacks to such a tax subsidy include the concern it would reward employers for doing what they do on their own without a tax subsidy and a lack of evidence that employers are systematically underinvesting in worker training.

The 115 th Congress is likely to face issues related to funding this research and specific issues arising from advances in agricultural biotechnology and the use of antibiotics in food-producing animals. Public investment in agricultural research has been linked to productivity gains, and subsequently to increased agricultural and economic growth. The U.S. Department of Agriculture's (USDA's) Research, Education, and Economics (REE) mission area has the primary federal responsibility of advancing scientific knowledge for agriculture. USDA-funded research spans the biological, physical, and social sciences related broadly to agriculture, food, and natural resources. USDA conducts its own research and administers federal funding to states and local partners primarily through formula funds and competitive grants. The outcomes are delivered through academic and applied research findings, statistical publications, cooperative extension, and higher education. USDA's research program is funded with nearly $2.9 billion per year of discretionary funding and about $120 million of mandatory funding. Congress traditionally reauthorizes and revises agricultural research programs in the five-year farm bill. The 2014 farm bill ( P.L. 113-79 ) expires on September 30, 2018. The 115 th Congress has begun considering the next farm bill. Some agricultural research programs will face reauthorization. Various agricultural, academic, and other interests may pursue changes to the scope or focus of those programs or request additional funding.

Currently, labeling GE food products is not required. The 114 th Congress passed a bill ( P.L. 114-216 ) signed into law in July 2016 to establish a "national bioengineered food disclosure standard." The U.S. Department of Agriculture (USDA) has two years to implement the labeling law. Food manufacturers can adopt either text, a symbol, or an electronic/digital link for identifying bioengineered foods. The labeling bill includes foods made through conventional genetic engineering technology as well as newer techniques in the definition of bioengineered foods. P.L. 114-216 also requires USDA to conduct a study within a year of enactment that identifies potential technological factors that could affect consumer access to bioengineered food disclosure through electronic or digital methods such as QR codes on food products read by smart phones. Concerns have been raised that such digital methods of disclosure could have differential impacts on those without cell phones (e.g., the elderly, low-income families) and those without access to high-speed broadband. The required study is to specifically address the availability of wireless or cellular networks, availability of landline telephones in stores, and particular factors that might affect small retailers and rural retailers as well as consumers. The development over the past several years of new technologies to genetically engineer plants, in particular novel gene-editing technologies, has raised new regulatory issues. USDA currently regulates GE plants under the Plant Protection Act (PPA; 7 U.S.C. §770). However, USDA has stated that newer technologies may fall outside the purview of the PPA and thus the department might have no regulatory jurisdiction over plants genetically engineered using these new technologies. This has raised important questions about how such genetically engineered plants are to be regulated as they are introduced. As genetically engineered plant varieties created by these techniques become more common, and as the public becomes more aware that these varieties are not regulated under the PPA, Congress might choose to revisit the 1986 framework that governs U.S. biotechnology regulation.

The Preservation of Antibiotics for Medical Treatment Act of 2017 ( H.R. 1587 ) and the Preventing Antibiotic Resistance Act of 2017 ( S. 629 ) have been introduced in the 115 th Congress. Both bills would restrict the use of some medically important antibiotics in food producing animals. In 2014, the Obama Administration launched the Presidential Advisory Council on Combating Antimicrobial Resistant Bacteria (PACCARB) initiative, a cross-departmental effort to preserve effective antibiotics for critical public and animal health needs. In May 2017, the advisory council held a public meeting that focused on animal health and antibiotics, and the challenges of antibiotic resistance. In March 2018, the advisory council drafted and passed a resolution expressing concern that the antibiotic resistance activities of the Department of Health and Human Services (HHS) and the U.S. Department of Agriculture (USDA) are being underfunded. USDA released its Antimicrobial Resistance Action Plan at the end of 2014, which included initiatives to develop research and to collect information on antibiotic use in animals. In 2017, as part of the effort to expand data collection, the USDA Animal and Plant Health Inspection Service launched studies on the use of antibiotics in cattle feedlots and in hog operations. The U.S. Food and Drug Administration (FDA) is responsible for evaluating human and animal drugs for safety and effectiveness under the Federal Food, Drug, and Cosmetic Act (FFDCA, 21 U.S.C. 301 et seq.). FDA is concerned about public health effects from certain antibiotic uses in food animals. According to FDA, foods of animal origin may carry pathogens that cause foodborne infections, and antibiotic use in animals that produce these foods may render the infections untreatable due to antibiotic resistance. In response to concern about antibiotic resistance, FDA issued guidance on the judicious use of antibiotics in animals. FDA finalized Guidance for Industry #213 in December 2013, giving animal drug sponsors three years to withdraw antibiotics for production uses (i.e., growth promotion or feed efficiency) and to update evidence for treatment and preventive or control uses. Guidance #213 became effective January 1, 2017. After this date, medically important antibiotics may only be used when necessary to treat and prevent diseases, and must be used under the supervision of a veterinarian. In June 2015, FDA finalized rules (80 Federal Register 31708) for the Veterinary Feed Directive (VFD)—prescriptions for animal drugs used in feed—that builds on FDA policy on judicious antibiotic use. Since January 1, 2017, all medically important antibiotics used in feed require a VFD. This requires that producers have an established veterinarian-client-patient relationship (VCPR) as defined in state regulations, or federal VFD regulations for states without VCPR requirements. A valid VCPR requires licensed veterinarians to be familiar with clients' farm and animals. Producers will now need prescriptions for non-feed antibiotics that previously were available over-the-counter. Finally, in May 2016, FDA issued a final rule (81 Fed eral Reg ister 29129) to expand its reporting on the distribution and use of antibiotics. In March 2017, the Government Accountability Office (GAO) issued "Antibiotic Resistance. More Information Needed to Oversee Use of Medically Important Drugs in Food Animals." The GAO report noted that HHS and USDA needed to develop a joint plan to collect antibiotic use data to be able to evaluate the effectiveness of antibiotic resistance policies. In April 2018 testimony before the Senate Appropriations Subcommittee on Agriculture, Rural Development, Food and Drug Administration, and Related Agencies, FDA Administrator Gottlieb stated that FDA would be issuing a plan in a "couple months" to ensure antibiotics are judiciously used in the farm setting.

Some of the biomedical R&D issues that the 115 th Congress may face include those related to the budget and oversight of the National Institutes of Health, the role the Food and Drug Administration in approving new medicines and laboratory tests, and advances in precision medicine and genomic editing. The National Institutes of Health (NIH) is the lead federal agency conducting and supporting biomedical research. The agency was provided with $37 billion in funding for FY2018 for basic, clinical, and translational research in NIH's laboratories as well as in research institutions nationwide. The extramural research program (83% of the NIH budget) provides grants, contracts, and training awards to support over 30,000 individuals at more than 2,500 universities, academic health centers, and research facilities. Over a five-year period, FY1999-FY2003, the NIH budget doubled in current dollars, but since FY2003 budget growth has decreased to below the rate of inflation. In constant dollars, NIH was funded at its highest level in FY2003 (not counting additional funding provided in FY2009 through the ARRA). The 21 st Century Cures Act ( P.L. 114-255 ) authorizes to be appropriated $4.8 billion for NIH over a 10-year period (FY2017-FY2026), averaging slightly under a half billion per year. However, the funding is not guaranteed and must be provided each year in subsequent appropriations acts. These appropriations totaled $352 million in FY2017 and $496 million in FY2018. These funds may only be used for four specified projects: (1) the Precision Medicine Initiative, $1.455 billion total for FY2017-FY2026; (2) the Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative, $1.511 billion total for FY2017-FY2026; (3) cancer research, $1.8 billion total for FY2017- FY2023; and (4) regenerative medicine using adult stem cells, $30 million total for FY2017-FY2020. The 21 st Century Cures Act makes a number of other policy changes, such as modifying the NIH strategic planning process, altering the agency's reporting requirements, and reducing the administrative burden for researchers, among other things.

FDA's total program level, the amount that FDA can spend, is composed of direct appropriations and user fees paid by the regulated industry. The human drugs program comprises the largest portion of FDA's total program level (about 31% of FDA's enacted FY2018 level). The 21 st Century Cures Act ( P.L. 114-255 ), signed into law on December 13, 2016, made several changes to the drug, biologic, and device approval pathways at FDA. Among other things, the law included various provisions to help accelerate development and review of certain medical products. For example, the law directs the Secretary of Health and Human Services to facilitate an "efficient development program for, and expedite review of" eligible regenerative advanced therapies (including cell therapy, therapeutic tissue engineering products, human cell and tissue products); creates a limited population pathway for antibacterial drugs to treat a serious or life-threatening infection; facilitates development, review, and approval of genetically targeted drugs and variant protein targeted drugs with respect to rare diseases or conditions that are serious or life-threatening; and establishes a priority review program to incentivize development of treatments for agents that present a national security threat. To help fund the FDA activities and programs authorized in 21 st Century Cures Act, the law established an FDA Innovation Account, to which a total of $500 million is authorized to be transferred over a nine-year period (FY2017-FY2025). Release of funds from the FDA Account is controlled through the annual appropriations process. On June 6, 2017, FDA submitted to Congress the "Work Plan and Proposed Funding Allocations of FDA Innovation Account," which sets out a plan for implementation of the programs and activities authorized or required by the 21 st Century Cures Act. In addition to implementation of activities required by the Cures Act, FDA has issued its own policy priorities related to, among other things, medical product innovation in the agency's "Healthy Innovation, Safer Families: FDA's 2018 Strategic Policy Roadmap." The roadmap discusses efforts aimed at promoting innovation in manufacturing to increase product reliability and safety, decrease interruptions in the supply of certain products, and lower costs.

In vitro diagnostic (IVD) devices provide information that is used by clinicians and patients to make health care decisions. IVDs are used in laboratory analysis of human samples and include commercial test products and instruments used in testing, among other things. Laboratory-developed tests (LDTs) are a class of IVD that is manufactured, including being developed and validated, and offered, within a single laboratory. LDTs may sometimes be referred to as "home-brew tests." Genetic tests are a type of diagnostic test that analyzes various aspects of an individual's genetic material (DNA, RNA, chromosomes, and genes). Most genetic tests are LDTs. The regulation of LDTs has been the subject of debate over the past decade. The Food and Drug Administration (FDA) has traditionally exercised enforcement discretion over LDT regulation. This means that most LDTs, and most genetic tests, have not been subject to FDA premarket review and therefore have not received FDA clearance or approval for marketing. Given the growing use of LDTs and genetic tests in clinical medicine, the FDA has in recent years revisited whether, and the extent to which, LDTs should be regulated. On July 31, 2014, the FDA notified the Senate Committee on Health, Education, Labor and Pensions and the House Committee on Energy and Commerce that it would be issuing draft guidance on LDT regulation. On October 3, 2014, the agency published a notice in the Federal Register announcing the availability of the guidance documents and requesting comments within 120 days to ensure their consideration in the development of final guidance. However, on November 18, 2016, the FDA indicated that it would postpone finalization of the draft guidance until the new Administration is in place. FDA summarized the comments it had received on the guidance documents in its January 2017 "Discussion Paper on Laboratory Developed Tests (LDTs)" and included in that paper the outline of a possible approach to LDT oversight. To date, no further action has been taken by the agency.

The mission of the PMI is "[t]o enable a new era of medicine through research, technology, and policies that empower patients, researchers, and providers to work together toward development of individualized care." The PMI primarily involves three federal agencies—the National Institutes of Health (NIH), the Food and Drug Administration (FDA), and the Office of the National Coordinator for Health Information Technology (ONC)—although other federal agencies have collaborated on and contributed to the effort. Precision medicine, also called personalized medicine, involves providing health care to an individual patient based on their unique characteristics, such as a genetic profile. NIH has awarded multiple grants to begin building an extensive biobank; develop health care provider organizations (HPOs); and develop recruitment strategies for a million-person national research cohort program, called the All of Us Research Program. To ensure underserved individuals have the opportunity to participate, NIH is working with the Health Resources and Services Administration (HRSA) to determine infrastructure needs for health centers to serve as HPOs. In addition, FDA has developed precisionFDA to facilitate data sharing and validation of new genomic assays in precision medicine. The 115 th Congress may be interested in policies that support ongoing or modified investments in precision medicine. In the PMI's initial year, FY2016, NIH received $200 million for the PMI: $70 million for the National Cancer Institute and $130 million for the research cohort. Pursuant to the authorizations of appropriations in the 21 st Century Cures Act ( P.L. 114-255 ), NIH received $40 million—in additional appropriations—for the PMI in FY2017 and $100 million in FY2018.

A new gene editing tool, based on clustered regularly interspaced short palindromic repeated DNA sequences, known as CRISPR-Cas9 offers the potential for substantial improvement over previous technologies in terms of ease of use, precision and efficiency, and cost. These characteristics have led many in the scientific and business communities to assert that CRISPR-Cas9 could lead to revolutionary advances across a broad range of areas—from medicine and public health to agriculture and the environment. Over the next 5 to 10 years, the National Academy of Sciences projects a rapid increase in the scale, scope, complexity, and development rate of biotechnology products, many enabled by CRISPR-Cas9. For example, CRISPR-Cas9 has increased both the pace of development and the variety of crops being genetically modified and it is beginning to be used in clinical trials for a variety of cancers, among other conditions. Concomitant with the promise of potential benefits associated with CRISPR-Cas9, such advances may also pose new risks and raise ethical concerns. For example, Chinese researchers have published the results of studies that used CRISPR-Cas9 in both viable and non-viable human embryos. While federal funds currently cannot be used for research involving human embryos in the United States, the Chinese studies and other research being conducted both domestically and internationally have sparked debates regarding the ethics of such research and prompted discussion about how existing law and regulation in the United States would apply to the conduct of this type of research, its clinical testing in humans, and specifically its applications in human embryos. Additionally, CRISPR-Cas9 related approaches are being considered by some researchers to reduce or eliminate the Zika virus and malaria. For example, effective reduction or elimination of the mosquito that serves as the primary vector for the transmission of Zika or malaria could save lives and substantially reduce costs. However, a 2016 report from the National Academy of Sciences indicates that existing mechanisms may be inadequate to assess the potential immediate and long-term environmental and public health consequences associated with the use of the technology. In the 115 th Congress, policymakers may want to examine the potential benefits and risks associated with the use of CRISPR-Cas9 gene editing, including the ethical, social, and legal implications of CRISPR-related biotechnology products. Congress also may have a role to play with respect to regulation, research and development, and economic competitiveness associated with CRISPR-Cas9 gene editing and future biotechnology products.

In addition to its general oversight of workplace safety, the federal government addresses the safety of laboratory personnel who work with infectious microorganisms through guidance such as Biosafety in Microbiological and Biomedical Laboratories (BMBL), published by the Department of Health and Human Services Centers for Disease Control and Prevention (CDC) and National Institutes of Health (NIH). BMBL sets "Biosafety Levels" for work with the highest-risk pathogens. BMBL guidance is often adopted as a requirement. For example, BMBL compliance is required of federal grant recipients. Biosecurity requirements, to protect the public from intentional and unintentional releases of pathogens, were first mandated by Congress in 1996, and expanded through subsequent reauthorizations. The Federal Select Agent Program, administered jointly by CDC and the U.S. Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS), oversees the possession of "select agents," certain biological pathogens and toxins with the potential to cause serious harm to public, animal, or plant health. All U.S. laboratory facilities—including those at government agencies, universities, research institutions, and commercial entities—that possess, use, or transfer select agents must register with the program and adhere to specified best practices. All persons given access to select agents must undergo background investigations conducted by the Federal Bureau of Investigation (FBI). Several incidents involving the mishandling of select agents in federal laboratories occurred in recent years. Samples of decades-old but viable smallpox virus were found in an FDA laboratory on an NIH campus. Laboratories at CDC, one of the select agent regulatory agencies, had incidents involving the anthrax agent, a virulent avian influenza virus, and Ebola virus. A Department of Defense laboratory inadvertently distributed viable instead of killed samples of the anthrax organism. Each incident was attributed, at least in part, to lapses in protocol or some other form of human error. Several incident reports have recommended improvements in the "culture of safety" in laboratories, standardized microbial handling practices, and better incident reporting, among other measures. In the 114 th and 115 th Congresses, the House Committee on Energy and Commerce has conducted investigations and held hearings on these lapses. The authorizations of appropriations for the Select Agent Program (7 U.S.C. 8401-8402 and 42 U.S.C. 262a) expired in 2007. Congress has continued to fund ongoing implementation and enforcement. The 115 th Congress may revisit program authority or regulations in light of recent incidents to determine whether current safety and security measures are adequate, as well as whether they allow important research on these pathogens to proceed. For Further Information [author name scrubbed], Specialist in Public Health and Epidemiology Science and technology play an important role in national defense. The Department of Defense (DOD) relies on a robust research and development effort to develop new military systems and improve existing systems. Issues that may come before the 115 th Congress regarding the DOD's S&T activities include budgetary concerns and the effectiveness of programs to transition R&D results into fielded products. The Department of Defense spends more than $80 billion per year on research, development, testing, and evaluation (RDT&E). Roughly 80-85% of this is spent on the design, development, and testing of specific military systems. Examples of such systems include large integrated combat platforms such as aircraft carriers, fighter jets, and tanks, among others. They also include much smaller systems such as blast gauge sensors worn by individual soldiers. The other 15-20% of the RDT&E funding is spent on what is referred to as DOD's Science and Technology Program. The S&T Program includes activities ranging from basic science to demonstrations of new technologies in the field. The goal of DOD's RDT&E spending is to provide the knowledge and technological advances necessary to maintain U.S. military superiority. DOD's RDT&E budget contains hundreds of individual line items. Congress provides oversight of the program, making adjustments to the amount of funding requested for any number of line items. These changes are based on considerations such as whether the department has adequately justified the expenditure or the need to accommodate larger budgetary adjustments. RDT&E priorities and focus, including those of the S&T portion, do not change radically from year to year, though a few fundamental policy-related issues regularly attract congressional attention. These include ensuring that S&T, particularly basic research, receives sufficient funding to support next generation capabilities; seeking ways to speed the transition of technology from the laboratory to the field; and ensuring an adequate supply of S&T personnel. Additionally, the impact of budgetary constraints, including continuing resolutions, on RDT&E may be of interest to the 115 th Congress. Specifically, senior DOD officials have been describing the need to develop and implement a third offset strategy—a strategy aimed at identifying new and innovative ways to maintain the dominance of U.S. military capabilities into the future—which would likely require increased investment in RDT&E.

Spent fuel from commercial nuclear reactors contains most of the original uranium that was used to make the fuel, along with plutonium and highly radioactive lighter isotopes produced during reactor operations. A fundamental issue in nuclear policy is whether spent fuel should be "reprocessed" or "recycled" to extract plutonium and uranium for new reactor fuel, or directly disposed of without reprocessing. Proponents of nuclear power point out that spent fuel still contains substantial energy that reprocessing could recover. However, reprocessed plutonium can also be used in nuclear weapons, so critics of reprocessing contend that federal support for the technology could undermine U.S. nuclear weapons nonproliferation policies. The potential commercial viability of reprocessing or recycling is also an issue. In the 1950s and 1960s, the federal government expected that all commercial spent fuel would be reprocessed, using "breeder reactors" that would convert uranium into enough plutonium to fuel additional commercial breeder reactors. Increased concern about weapons proliferation in the 1970s and the slower-than-projected growth of nuclear power prompted President Carter to halt commercial reprocessing efforts in 1977, along with a federal demonstration breeder project. Under President Reagan, Congress provided funding to restart the breeder demonstration project, but then halted project funding in 1983 while continuing to fund breeder-related research and development by the Department of Energy (DOE). Under President Clinton, research on producing nuclear energy through reprocessing was largely halted, although some work on the technology continued for waste management purposes. Under the George W. Bush Administration there was renewed federal support for reprocessing, with a proposal to complete a pilot plant by the early 2020s. Under the Obama Administration, plans for the pilot plant were halted and DOE's Fuel Cycle Research and Development Program was redirected toward development of technology options for a wide range of nuclear fuel cycle approaches, including direct disposal of spent fuel (the "once through" cycle), deep borehole disposal, and partial and full recycling. The Trump Administration proposed deep reductions in Fuel Cycle R&D in FY2018 and FY2019. However, the Consolidated Appropriations Act for 2018 ( P.L. 115-141 ) increased the program's funding from $208 million in FY2017 to $260 million in FY2018—a 26% boost. Another DOE program related to reprocessing policy is the Mixed Oxide Fuel Fabrication Facility (MFFF) under construction at the Department's Savannah River Site in South Carolina. MFFF would produce fuel for commercial nuclear reactors using surplus nuclear weapons plutonium, as part of an agreement with Russia to reduce nuclear weapons material. Critics of the project contend that MFFF would subvert U.S. nonproliferation efforts by encouraging the use of plutonium fuel. Because of rising costs, the Obama Administration proposed to halt the MFFF project in FY2017 and pursue alternative plutonium disposition options. The Trump Administration's FY2018 budget request also called for terminating MFFF. The FY2018 National Defense Authorization Act ( P.L. 115-91 ) authorized DOE to pursue an alternative disposal option if its total costs were found to be less than half of those for completing and operating MFFF. The Consolidated Appropriations Act for 2018 conformed to the NDAA authorizing language. For Further Information [author name scrubbed], Specialist in Energy Policy CRS Report R42853, Nuclear Energy: Overview of Congressional Issues , by [author name scrubbed] CRS Report RL34234, Managing the Nuclear Fuel Cycle: Policy Implications of Expanding Global Access to Nuclear Power , coordinated by [author name scrubbed] CRS Report R43125, Mixed-Oxide Fuel Fabrication Plant and Plutonium Disposition: Management and Policy Issues , by [author name scrubbed] and [author name scrubbed] All currently operating commercial nuclear power plants in the United States are based on light water reactor (LWR) technology, in which ordinary water cools the reactor and acts as a neutron moderator to help sustain the nuclear chain reaction. DOE has long conducted research and development work on other, non-LWR nuclear technologies that could have advantages in safety, waste management, and cost. A growing number of private-sector firms are pursuing commercialization of advanced nuclear technologies as well. Advanced nuclear energy technologies include high-temperature gas-cooled reactors, liquid metal-cooled reactors, and molten salt reactors (in which the nuclear fuel is dissolved in the coolant), among a wide range of other concepts. Many of these concepts would involve nuclear chain reactions using fast neutrons, which are not slowed by a moderator. Research on advanced reactor coolants, materials, controls, and safety is carried out by DOE's Advanced Reactor Technologies program. The Trump Administration requested $64 million for the program in FY2018, a 28% reduction from the FY2017 level. The program received $155 million in the Consolidated Appropriations Act for 2018, a 78% increase over FY2017. Of that amount, $60 million is to provide support for engineering and design of non-LWR and advanced LWR technologies, and for "regulatory development," according to the bill's explanatory statement. Private-sector nuclear technology companies contend that a major obstacle to commercializing advanced reactors is that the Nuclear Regulatory Commission's (NRC's) licensing process is based on existing LWR technology. They have urged NRC to develop a licensing and regulatory framework that could apply to all nuclear concepts. They also have recommended a "staged review process" to provide conditional NRC approval for advanced reactor designs at key milestones toward the issuance of an operating license. NRC and DOE are currently implementing the Joint Advanced Non-Light Water Reactors Licensing Initiative to adapt existing general design criteria for LWRs for use by advanced reactor license applications. Under that initiative, NRC issued "Guidance for Developing Principal Design Criteria for Non-Light Water Reactors" on April 9, 2018. NRC is also supporting industry efforts to develop guidance for technology-neutral reactor licensing. Legislation to promote advanced nuclear power technologies is being considered in the 115 th Congress. The Senate passed the Nuclear Energy Innovation Capabilities Act ( S. 97 ) on March 7, 2018. A major provision of the bill would authorize DOE national laboratories or other DOE-owned sites to host reactor demonstration projects sponsored fully or partly by the private sector. It would also require DOE to determine the need for a fast-neutron test reactor and authorize grants to help pay for NRC licensing of advanced reactor designs. Similar provisions, except for the licensing grants, are included in the Department of Energy Research and Innovation Act ( H.R. 589 ), passed by the House on January 24, 2017, and reported by the Senate Committee on Energy and Natural Resources March 9, 2018. Some public-private R&D on advanced nuclear technology is already being conducted at national labs under DOE's Gateway for Accelerated Innovation in Nuclear (GAIN) program. The Consolidated Appropriations Act for 2018 provides $35 million for DOE to determine the need for a fast neutron test reactor. For Further Information [author name scrubbed], Specialist in Energy Policy CRS Insight IN10765, Small Modular Nuclear Reactors: Status and Issues , by [author name scrubbed] Biofuels—liquid transportation fuels produced from biomass feedstock—are often described as an alternative to conventional fuels. Some see promise in producing liquid fuels from a domestic feedstock that may reduce dependence on foreign sources of oil, contribute to improving rural economies, and lower greenhouse gas emissions. Others regard biofuels as potentially causing more harm to the environment (e.g., air and water quality concerns), encouraging landowners to put more land into production, and being prohibitively expensive to produce. The debate about the feasibility of biofuels is complex, as policymakers consider a multitude of factors (e.g., feedstock costs, timeframe to reach substantial commercial-scale advanced biofuel production). The debate can be even more complicated when considering that biofuels may be produced using numerous biomass feedstocks and conversion technologies. Thus, for each specific biofuel, a thorough assessment of the costs and benefits requires specific knowledge of the various factors involved. Congress has expressed interest in biofuels for decades, with most of its attention on the production of "first-generation" biofuels (e.g., cornstarch ethanol). Farm bills have had a significant effect on biofuel research and development. Starting in 2002, the farm bills have contained an energy title with several programs focused on assisting biofuel production (see " Agriculture " section for additional farm bill related research). While commercial-scale production of "first-generation" biofuels is well established, commercial-scale production for some advanced biofuels (e.g., cellulosic ethanol) is in its infancy. In 2007, Congress expanded one policy that has supported an increase in advanced biofuel production—the Renewable Fuel Standard (RFS). The RFS requires U.S. transportation fuel to contain a minimum volume of biofuel, a significant percentage of which is gradually to come from advanced biofuels. However, the RFS has been under scrutiny for various reasons, including the Environmental Protection Agency (EPA) exercising its regulatory authority to issue a waiver and reduce the total renewable fuel volume below what was required by statute and concerns about RFS compliance. This has created significant uncertainty for certain stakeholders, with the result that some of the advanced biofuel targets are not being met. An overarching issue is that the policy may require more biofuel to be produced than can be used given the existing motor fuel distribution infrastructure and the limited fleet of passenger vehicles that are built to run on higher percentage blends of biofuels. A continuing issue is whether a domestic biofuel industry is necessary for national defense, and what, if any, role the military might take regarding biofuel production and purchase. Congress could also consider whether to modify various biofuel promotional efforts, or to maintain the status quo.

They may facilitate exploration of previously inaccessible resources, provide cost efficiencies in a low-oil-price environment, address safety and environmental concerns, and resolve obstacles in emerging sectors such as U.S. offshore wind. Private industry, universities, and government are all involved in ocean energy R&D. At the federal level, the Department of Energy (DOE) and the Department of the Interior (DOI) both support ocean energy research. One area of interest involves deepwater oil and gas operations. Industry interest in expanding deepwater activities, improving efficiency, and reducing costs has prompted improvements in drilling technologies and steps toward automated monitoring and maintenance. The oil and gas industry and federal regulators also have focused on safety improvements to reduce the likelihood of catastrophic oil spills in deep water. In April 2016, DOI released final safety regulations that tighten requirements for offshore blowout preventer systems and other well control equipment. President Trump ordered DOI to review the regulations in Executive Order 13795. A 2018 timetable for revisions has been announced in the federal Regulatory Agenda . Issues include the cost to industry of meeting the rule's technological requirements and the time required to do so. Congress may also consider technology issues related to offshore drilling in the Arctic, where sea ice and infrastructure gaps pose challenges for the economic viability and safety of mineral exploration. A focus of industry R&D is on technology to extend the Arctic drilling season beyond the brief periods where sea ice is absent—for example, by developing ice-capable mobile offshore drilling units (MODUs). DOI finalized safety regulations for Arctic exploratory drilling in July 2016. President Trump's Executive Order 13795 ordered DOI to review these regulations, and DOI's 2018 Regulatory Agenda includes an anticipated rule revision. Some have argued that the regulations are too costly for industry and give inadequate weight to available technologies (such as those for well capping) that could reduce safety costs. Others question whether any rules or technologies can adequately ensure drilling safety in the Arctic given the environmental risks. Among renewable ocean energy sources, only wind energy is poised for commercial application in U.S. waters. In December 2016, the first U.S. offshore wind farm, off of Rhode Island, began regular operations. A focus of R&D is technology to increase offshore turbine efficiency and reduce costs, including floating turbines for deep waters, where resources may be more abundant and user conflicts fewer. Other research explores improvements to electrical infrastructure, such as integrating transmission networks for multiple projects. An issue for Congress is whether and how to support or incentivize offshore wind development and other ocean renewables.

When completed, ITER is to be the world's largest fusion reactor and the first capable of producing more energy than it consumes. Although the energy output from ITER will not be harnessed to produce electricity, fusion researchers see ITER as the next step toward implementation of fusion energy as a power source. ITER is an international collaboration. Along with the United States, the partners are the European Union, China, India, Japan, Russia, and South Korea. The United States withdrew from the initial design phase of ITER in 1998 at congressional direction, largely because of concerns about cost and scope. The project was restructured, and the United States rejoined in 2003. The formal international agreement to build the facility was approved in 2006. The European Union, as host, is responsible for 45% of the construction cost, while the United States and the other participating countries are responsible for 9% each. Most of the U.S. share (which is $122 million in FY2018) is being contributed in kind, in the form of components and equipment sourced mostly from U.S. companies, universities, and national laboratories. In recent years, ITER management issues, schedule delays, and cost growth have led to repeated proposals in Congress to terminate U.S. participation. A central issue is that U.S. funding for ITER may be crowding out funding for the domestic fusion research program. DOE budget documents show the cost of U.S. participation in ITER in FY2020 and beyond as "to be determined" once the Administration decide whether to continue participating in the project. The construction phase of ITER is planned for completion in 2027. Once operational, the lifespan of the facility is expected to be 15-25 years. During the operation phase, and during subsequent deactivation and decommissioning, the agreed U.S. cost share is 13%. For More Information [author name scrubbed], Specialist in Science and Technology Policy Science and technology play an increasingly large role in environmental issues. Science- and technology-related environmental issues that may come before the 115 th Congress include climate change science, carbon sequestration, and water science. Climate change, including the policy questions of whether and how the federal government might address it, continues as a matter of discussion in the 115 th Congress. Science and technology considerations underpin the congressional deliberations on the topic. Despite portrayals in popular media about controversies in climate change science, almost all climate scientists agree on certain important points: the Earth's climate has been changing, with overall warming since the mid-20 th century; human-related emissions of greenhouse gases (GHG) are accumulating in the atmosphere and carbon dioxide is increasing acidity of the oceans; and rising GHG atmospheric concentrations will lead to additional global warming and other climate changes. The latest major U.S. assessment, the Climate Science Special Report (CSSR), was released in October 2017 by the U.S. Global Change Research Program (USGCRP). It stated It is extremely likely [>95% likelihood] that human influence has been the dominant cause of the observed warming since the mid-20 th Century. For the warming over the last century, there is no convincing alternative explanation supported by the extent of the observational evidence. A large majority of scientists also agree that continued GHG emissions would lead to important adverse impacts—even catastrophic ones for some populations; some, however, consider that even under current GHG emission trajectories, the impacts would be modest and manageable. In the near term, the focus of climate change scientific research may shift increasingly toward greater precision in climate projections, localized climate projections, impacts on society, and probabilistic characterization of uncertainties, especially to assist local and regional impact assessment and risk management decision making. In light of the growing consensus on the science of human-induced climate change, Congress may shift attention more toward assessment of options to manage risks. Deliberations include the appropriate magnitude and emphasis of federal support for climate-related technology for GHG emission abatement, geoengineering, and adaptation or resilience to impacts. The U.S. Global Change Research Program (USGCRP) is an interagency mechanism, required by the Global Change Research Act of 1990 ( P.L. 101-606 ) that coordinates and integrates global change research across 10 government agencies. For FY2017, USGCRP expressed three thematic priorities: climate, water cycle extremes in the context of climate change, and methane cycling in the context of the carbon cycle. The current Administration has not reported priorities or budget proposals to Congress as required by the act. Most federal climate change-related funding is aimed at advancing "clean energy," the definition of which varies among interested groups. Most human-related GHG emissions come from production, distribution, and combustion of fossil fuels, particularly for electricity generation and transportation. Many analysts see a decades-long path to decarbonization of the world's energy economy as a primary option to halting the human influence on climate, while potentially providing security and health benefits. Some see potential carbon capture, utilization, and sequestration (CCUS) technologies as key to preventing carbon dioxide emissions while preserving a large place for coal and other fossil fuels in the energy economy. Still others advocate development of geoengineering technologies, and international governance regimes, to intentionally modify the climate, particularly should climate change rapidly and adversely. (Reducing GHG emissions would have a slower but more permanent effect on global climate.) Members may deliberate on the appropriate degree and means of federal support for advancing and deploying new technologies. Because some innovative technologies are still in the research phase, and because of market inefficiencies and barriers to economical uptake of some technologies, Congress has provided billions of dollars of federal support, including numerous tax incentives, for energy technologies, unevenly distributed across types of technologies. The programs range from basic research, through technology development and demonstration of selected technologies, to incentives to promote their commercial deployment. Some focus on "supply-push" of technologies, while others emphasize "demand-pull." Existing programs support technologies that would lower GHG emissions (e.g., more efficient and renewable energy technologies). Cleaner energy technologies can produce public health benefits additional to climate benefits, while shifts in the energy economy can also pose transitional challenges to employment and communities. The magnitude of federal expenditures for climate change, their effectiveness, and priorities may be topics for Congress, particularly in light of budget objectives. The 115 th Congress may consider legislation that affects existing programs or establishes new ones. A number of Members support existing and extended tax incentives that influence the types and rates of technology advance. In addition, legislation has been proposed prior to the 115 th Congress to levy GHG emission fees or "carbon taxes" to promote cleaner technologies, broaden the tax base, reduce the projected budget deficit, and assist workers and communities challenged by the ongoing transitions in the energy sector, among other proposed uses of revenues. Pricing of GHG emissions would promote demand for more efficient and lower-emitting technologies, potentially driving innovation and market-based technological change. Emission fees could also be used in part to finance basic research in which the private sector tends to underinvest because of its risks and the difficulty of capturing all the benefits of successful R&D. Federal programs for technologies to support adaptation or resilience to future climate change have also been proposed in the 115 th Congress. Because the climate will continue to change, due to both natural and human-related causes, Congress may address the federal role in facilitating effective state, local, and private decision making to anticipate and be resilient to changes. It may also consider efforts already begun to incorporate climate change projections into federal agency management of federal resources, infrastructure and operations, and requirements and incentives in federal programs that may encourage or impede adaptation. Effective decisions would all depend on the adequacy and appropriate use of scientific information and available technologies.

CCS could reduce the amount of CO 2 emitted to the atmosphere while allowing the continued use of fossil fuels at power plants and other large industrial facilities. An integrated CCS system would include three main steps: (1) capturing CO 2 at its source and separating it from other gases; (2) purifying, compressing, and transporting the captured CO 2 to the sequestration site; and (3) injecting the CO 2 into subsurface geological reservoirs. Following its injection into a subsurface reservoir, the CO 2 would need to be monitored for leakage and to verify that it remains in the target geological reservoir. Once injection operations cease, a responsible party would need to take title to the injected CO 2 and ensure that it stays underground in perpetuity. Recently, CCS has been referred to as CCUS, carbon capture, utilization , and storage, to incorporate the use of captured CO 2 in addition to its permanent storage underground. Uses include manufacturing products using CO 2 , injecting CO 2 underground to enhance oil recovery, and other uses. The U.S. Department of Energy (DOE) has pursued research and development of aspects of the three main steps leading to an integrated CCS system since 1997. CCS-focused R&D has come to dominate the coal program area within DOE Fossil Energy Research and Development (FER&D) since 2010. Congress has appropriated more than $4 billion in total from FY2012-FY2018 for CCS-related research, development, and demonstration (RD&D) at DOE's Office of Fossil Energy. That total does not include $3.4 billion appropriated for CCS-related activities within the American Recovery and Reinvestment Act ( P.L. 111-5 ). Authority to expend Recovery Act funding expired at the end of FY2015. To date, no commercial ventures in the United States capture, transport, and inject large quantities of CO 2 (e.g., 1 million tons per year or more) solely for the purposes of carbon sequestration. Globally, however, two fossil-fueled power plants currently generate electricity and capture CO 2 in large quantities: the Boundary Dam plant in Canada and the Petra Nova plant in Texas. Both plants retrofitted post-combustion capture technology to units of existing plants. A third fossil-fueled electricity-generating operation, the Kemper County Energy Facility in Mississippi, was scheduled to begin CCS operations by now, but cost overruns and delays in construction and operations led to the suspension of the plant's CCS component on June 28, 2017. Congress continued to provide support for CCS R&D within DOE's FER&D program in FY2018, providing nearly $727 million to FER&D in total, an increase of nearly $59 million, a 9% increase compared to FY2017. The Trump Administration's FY2019 budget request, however, would shift away from CCS R&D to fund other priorities, and would cut the overall FER&D budget by nearly $225 million compared to what Congress enacted for FY2018. The FY2019 budget request cites early-stage research as its focus: "This budget request focuses DOE resources toward early-stage R&D and reflects an increased reliance on the private sector to fund later-stage research." Specifically, the carbon capture and carbon storage subprograms would receive $40 million total under the Administration's request, compared to nearly $200 million for FY2018, an 80% reduction. Given Congress' continued interest in supporting CCS-related R&D within DOE, it is likely that the Administration's proposed funding reductions will face congressional opposition in the FY2019 budget.

The research issues related to developing, using, and protecting water supplies and aquatic ecosystems along the nation's coasts and in inland areas are diverse. Because of this diversity, federal research activities and facilities span numerous departments, agencies, and laboratories. The federal government also supports water research through grants to universities and other researchers. In recent years, federal agencies have sponsored various prize competitions related to water data, science, and technologies, and developed cooperative arrangement with various entities. Drinking water contamination incidents (e.g., algal toxins in Lake Erie and lead in drinking water in Flint, MI) and recent droughts, floods, and storms also have increased interest in innovative technologies and practices (including nature-based approaches often referred to as green infrastructure ) and the science to support them. The 115 th Congress may consider multiple water research and technology topics which can be broadly divided into water and aquatic ecosystem information, water infrastructure and use, and water quality. Information on water quantity, quality, and conditions and aquatic ecosystems and species include observations, forecasts, and associated modeling (including surface water and groundwater modeling under various climate scenarios). Science and research agencies collect data remotely and in situ ; they use a wide variety of traditional and new technologies and techniques that inform water-related decisions for infrastructure, agriculture, and drinking water and wastewater services. Some of the inland and coastal water and ecosystem research topics that may be before the 115 th Congress include the following: water monitoring infrastructure and programs, including water quality monitoring activities, stream gauges, and remote sensing investments (see " Earth-Observing Satellites "); water conditions along coasts (e.g., storm-surge forecasts; relative sea-level rise rates, causes, and effects such as groundwater salinization; coastal and estuarine monitoring and restoration; and nature-based coastal management); altering the operation of existing reservoirs (e.g., using seasonal forecasts to enhance water supply, and forecast-informed operations for flood management); monitoring and management of invasive species and harmful algal blooms; access to water data (e.g., the Open Water Data Initiative, National Water Center, Drought Monitor); and coordination and direction of the federal water science and research portfolio. Water infrastructure research encompasses how to prolong and improve the performance of existing coastal and inland water infrastructure as well as the development of next-generation infrastructure technologies. The demand for infrastructure is in part determined by how efficiently water is used (e.g., irrigation technologies, drinking water distribution, and household water products). Some infrastructure and water use research topics include water augmentation technologies and science to support their adoption, including groundwater recharge, stormwater capture, water reuse, and brackish and seawater desalination; technologies and materials for monitoring and rehabilitating aging infrastructure, such as materials selection, construction and repair techniques, and detection technologies (e.g., structural health monitors and leak detection); water efficiency technologies, practices, and programs (e.g., improved irrigation technologies (see " Agricultural Research "), and water-efficient product labeling); and technologies to enhance infrastructure resilience to droughts, floods, hurricanes, and other natural hazards (e.g., technologies and methods to sustain collection and distribution systems, treatment plants, and related infrastructure). Water quality in surface water, groundwater, and tap water is important for public health and environmental protection. Technologies for preventing contamination and for identifying and treating existing contamination is an ongoing research topic for the federal government. Some research topics include analytical methods and treatment technologies to detect and manage emerging contaminants (e.g., cyanotoxins associated with harmful algal blooms, and perfluoroalkyl substances [PFASs]); technologies to prevent and manage contamination issues at drinking water treatment plants and in distribution systems (e.g., real-time monitoring, treatment to minimize disinfection byproducts, and lead pipe corrosion control); and innovative water protection technologies and practices, including methods for protecting drinking water sources for public water system from contamination (e.g., nature-based stormwater management, watershed management approaches, and nonpoint source pollution management).

Some of the issues that the 115 th Congress may consider include how the Department of Homeland Security performs research and development and federal efforts to develop and procure new medical countermeasures against chemical, biological, radiological, and nuclear agents. The Department of Homeland Security (DHS) has identified five core missions: to prevent terrorism and enhance security, to secure and manage the borders, to enforce and administer immigration laws, to safeguard and secure cyberspace, and to ensure resilience to disasters. New technology resulting from research and development can contribute to all these goals. The Directorate of Science and Technology has primary responsibility for establishing, administering, and coordinating DHS R&D activities. The Domestic Nuclear Detection Office (DNDO) is responsible for R&D relating to nuclear and radiological threats. Several other DHS components, including the Coast Guard, also fund R&D and R&D-related activities related to their missions. Coordination of DHS R&D is a long-standing congressional interest. In 2012, GAO concluded that because so many components of the department are involved, it is difficult for DHS to oversee R&D department-wide. In January 2014, the joint explanatory statement for the Consolidated Appropriations Act, 2014 ( P.L. 113-76 ) directed DHS to implement and report on new policies for R&D prioritization. It also directed DHS to review and implement policies and guidance for defining and overseeing R&D department-wide. In July 2014, GAO reported that DHS had updated its guidance to include a definition of R&D and was conducting R&D portfolio reviews across the department, but that it had not yet developed policy guidance for DHS-wide R&D oversight, coordination, and tracking. In December 2015, the explanatory statement for the Consolidated Appropriations Act, 2016 ( P.L. 114-113 ) stated that DHS "lacks a mechanism for capturing and understanding research and development (R&D) activities conducted across DHS, as well as coordinating R&D to reflect departmental priorities." The Common Appropriations Structure that DHS introduced in February 2016 in its FY2017 budget request includes an account titled Research and Development for each DHS component. It remains to be seen whether this change will help to address congressional concerns about DHS-wide R&D coordination. DHS has reorganized its R&D-related activities several times. In December 2017, it established a new Countering Weapons of Mass Destruction Office (CWMDO), consisting of DNDO, most functions of the Office of Health Affairs (OHA), and some other elements. DNDO and OHA were themselves both created, more than a decade ago, largely by reorganizing elements of the S&T Directorate. The 115 th Congress may consider legislation to authorize the establishment and activities of CWMDO. Meanwhile, DNDO continues to conduct R&D as an office within CWMDO. For Further Information [author name scrubbed], Specialist in Science and Technology Policy The anthrax attacks of 2001 highlighted the nation's vulnerability to biological terrorism. The federal government responded to these attacks by increasing efforts to protect civilians against chemical, biological, radiological, and nuclear (CBRN) terrorism. Effective medical countermeasures, such as drugs or vaccines, could reduce the impact of a CBRN attack. Policymakers identified a lack of such countermeasures as a challenge to responding to the CBRN threat. To address this gap, the federal government created several programs to encourage private sector development of new CBRN medical countermeasures. Despite these efforts, the federal government still lacks medical countermeasures for many CBRN threats, including Ebola. The Biomedical Advanced Research and Development Authority (BARDA) and Project BioShield are two key pieces of the federal efforts supporting the development and procurement of new CBRN medical countermeasures. BARDA directly funds the advanced development of countermeasures through contracts with private sector developers. Project BioShield provides a procurement mechanism to remove market uncertainty for countermeasure developers. It allows the federal government to agree to buy a countermeasure up to 10 years before the product is likely to finish development. Congress has modified these and related programs to improve their performance, efficiency, and transparency to oversight. However, some key issues remain unresolved, including those related to appropriations, interagency coordination, and countermeasure prioritization. In addition to questions regarding the amount of funding, Congress may decide whether to return to funding Project BioShield through a multiyear advance appropriation. Policymakers may consider whether the new planning and transparency requirements have sufficiently enhanced coordination of the multiagency countermeasure development enterprise. Additionally, Congress may consider whether the countermeasure prioritization process appropriately balances the need to address traditional threats such as anthrax and smallpox with the threat posed by emerging infectious diseases such as Ebola. For Further Information [author name scrubbed], Specialist in Science and Technology Policy The rapid pace of advancements in information technology presents several issues for congressional policymakers, including those related to cybersecurity, artificial intelligence, broadband deployment, access to broadband networks and net neutrality, public safety networks, emergency alerting, the Internet of Things, cryptography and law-enforcement challenges, and federal networking R&D. During the 113 th and 114 th Congress, there were a number of legislative proposals relating to cybersecurity, including the enactment of several laws with provisions on the security of federal information systems and the sharing of cybersecurity information across critical infrastructure sectors, among other issues. Those laws, along with more than 50 other statutes, presidential directives, and related authorities, provide a complex federal policy framework for U.S. cybersecurity. The 115 th Congress has faced a number of significant issues related to cybersecurity, in addition to the oversight of enacted laws. Among those issues are cybersecurity for critical infrastructure, given that most of it is not owned by the federal government and sectors of concern such as the recently designated election infrastructure subsector are not subject to federal regulation; prevention of and response to cybercrime, especially given its substantially international character; the relationship between cyberspace and national security, including information operations aimed at election infrastructure and political campaigns; and ways that federal funding should be invested to protect information systems and networks. In addition to such short- and medium-term issues, Congress may consider responses to a number of long-term challenges, including the following: design— the degree to which information systems can be designed with security built in, in the face of economic obstacles and the other challenges; incentives— ways to correct an economic incentive structure for cybersecurity that has often been called distorted or even perverse, with cybercrime widely regarded as cheap, profitable, and comparatively safe for the criminals, while cybersecurity is often considered expensive and imperfect, with uncertain economic returns; consensus— finding consensus on a consistent and effective model for approaching cybersecurity, given stakeholders from different sectors and different work subcultures with varying needs, goals, and perspectives; and environment— a rapidly evolving cyberspace environment that both complicates the threat environment and may pose opportunities for shaping the direction of that evolution toward greater security, including, for example, the growth and influence of cloud computing, social media, disruptive technologies such as blockchain, and the "The Internet of Things."

Since January 2017, congressional activities on AI have included multiple committee hearings in both the House of Representatives and the Senate, the introduction of numerous AI-focused bills, and a variety of congressional briefings, including those conducted by the Congressional AI Caucus and the Congressional Middle Class Jobs Caucus. Activity related to AI is likely to continue in the 115 th Congress. Generally, AI is considered to be computerized systems that work and react in ways commonly thought to require intelligence, encompassing many methodologies and applications. Common examples include machine learning, computer vision, natural language processing, and applications in robotics and autonomous vehicles. In addition to transportation, AI is already being employed across a variety of sectors, including healthcare, agriculture, manufacturing, and finance. Current AI technologies fall into a category called "narrow AI," meaning that they are highly tailored to particular tasks. In contrast, potential future AI systems that exhibit adaptable intelligence across a range of cognitive tasks, often referred to as "general AI," are unlikely to be developed for at least decades, if ever, according to most researchers. Potential policy considerations for AI span cross-sector and sector-specific topics, in both the defense and non-defense spaces. For example, broad concerns have focused on workforce impacts from the implementation of AI and AI-driven automation, including potential job losses and the need for worker retraining; the balance of federal and private sector funding for AI; international competition in AI research and development (R&D) and deployment, particularly with China and Russia; the development of standards and testing for AI systems; the need for and effectiveness of federal coordination efforts in AI; and incorporation of privacy, security, transparency, and accountability considerations in AI systems. Particular considerations for AI in the defense space have included the balance of human and automated decisionmaking in military operations; potential changes to the Department of Defense's acquisitions processes for defense adaptation of commercially developed AI systems; and private sector concerns about the use of AI R&D in combat situations. For Further Information [author name scrubbed], Analyst in Science and Technology Policy CRS In Focus IF10608, Overview of Artificial Intelligence , by [author name scrubbed] Broadband—whether delivered via fiber, cable modem, mobile or fixed wireless, copper wire, or satellite—is increasingly the technology underlying telecommunications services such as voice, video, and data. Broadband technologies have been deployed throughout the United States primarily by the private sector. These providers include telephone, cable, wireless, and satellite companies as well as other entities that provide commercial telecommunications services to residential, business, and institutional customers. Since the initial deployment of broadband in the late 1990s, many in Congress have viewed broadband infrastructure deployment as a means to improve regional economic development, and in the long term, to create jobs. As such, Congress and successive Administrations have focused on addressing gaps related to broadband availability and adoption. Of particular concern is the lack of adequate broadband availability in rural and tribal areas, where the cost of serving large geographical areas, coupled with low population densities, often reduce economic incentives for telecommunications providers to invest in and maintain broadband infrastructure and service. Broadband adoption is also an issue, wherein approximately one in four Americans have broadband available, but choose not to subscribe. Populations continuing to lag behind in broadband adoption include people with low incomes, seniors, minorities, the less-educated, non-family households, and the non-employed. The 115 th Congress is addressing, considering, or may consider a range of broadband-related issues. These include infrastructure legislation that may include incentives for broadband buildout, reauthorization of the broadband loan program in the farm bill, the development of new wireless spectrum policies, and lowering or removing regulatory barriers to broadband infrastructure facilities deployment faced by private sector providers. Additionally, the 115 th Congress may choose to examine the existing regulatory structure and consider possible revision of the 1996 Telecommunications Act and its underlying statute, the Communications Act of 1934. Both the convergence of telecommunications providers and markets and the transition to an Internet Protocol (IP) based network have, according to a growing number of policymakers, made it necessary to consider revising the current regulatory framework. How a possible revision might create additional incentives for investment in, deployment of, and subscribership to U.S. broadband infrastructure may be among many issues under consideration. To the extent that Congress may consider various options for further enhancing broadband deployment, a key issue is how to develop and implement federal policies intended to increase the nation's broadband availability and adoption, while at the same time minimizing any deleterious effects that government intervention in the marketplace may have on competition and private sector investment.

The move to place restrictions on the owners of the networks that compose and provide access to the internet, to ensure equal access and non-discriminatory treatment, is referred to as "net neutrality." While there is no single accepted definition of "net neutrality," most agree that any such definition should include the general principles that owners of the networks that compose and provide access to the internet (i.e., broadband access providers) should not control how consumers lawfully use that network, and should not be able to discriminate against content provider access to that network. A focal point in the debate centers on whether it is necessary for policymakers to take steps to ensure "unfettered" access to the Internet for content, services, and applications providers, as well as consumers, and if so, what these steps should be. Some policymakers contend that more specific regulatory guidelines are necessary to protect the marketplace from potential abuses which could threaten the net neutrality concept. Others contend that existing laws and policies are sufficient to deal with potential anti-competitive behavior and that additional regulations would have negative effects on the expansion and future development of the internet. Broadband regulation and the Federal Communications Commission's (FCC) authority to implement such regulations is an issue of growing importance in the wide ranging policy debate over broadband access. What, if any, action should be taken to ensure "net neutrality" is part of the overall discussion? The FCC, in 2015, adopted rules (2015 Order) that established a comprehensive regulatory framework to address the regulation of broadband internet access providers. The 2015 Order contained among its provisions those that reclassified such services as a telecommunications service and established bright line conduct rules for providers. However, the FCC, in December 2017, adopted new rules (2017 Order) that largely reverse the 2015 regulatory framework and shift much of the oversight from the FCC to the Federal Trade Commission and the Department of Justice. The FCC's move to adopt the 2017 Order has reopened the debate over what the appropriate framework is to ensure an open internet and whether Congress should enact legislation to establish this framework. A consensus on what that framework should entail remains elusive. Some Members of Congress support the less regulatory approach contained in the 2017 Order, which they argue will stimulate broadband investment, deployment, and innovation. Others support the regulatory framework adopted in the 2015 Order, which provides for a more stringent regulatory framework, and is needed, they state, to protect content, services, and applications providers, as well as consumers, from potential discriminatory behaviors which conflict with net neutrality principles. Still others, while supporting a framework containing specific behavioral rules to address potential anticompetitive practices, do not support the telecommunications services classification. Whether Congress will take action to amend existing law to provide guidance and more stability to FCC authority remains to be seen. For Further Information [author name scrubbed], Specialist in Telecommunications Policy CRS Report R40616, The Net Neutrality Debate: Access to Broadband Networks , by [author name scrubbed] The Middle Class Tax Relief and Job Creation Act of 2012 ( P.L. 112-96 ) authorized the Federal Communications Commission (FCC) to allocate additional spectrum to public safety use, and created the First Responder Network Authority (FirstNet). The act also authorized FirstNet to establish a new, nationwide broadband network for public safety, and provided $7 billion in funding for the project. The network is intended to address the communication problems first responders experienced during September 11, 2001, whereby public safety systems and equipment were not interoperable, and responders could not communicate or coordinate an effective response. Congress authorized FirstNet to enter into a public-private partnership to deploy the network. In March 2017, FirstNet selected AT&T, through a competitive bidding process, as its partner. Congress has provided oversight of this important project for the past five years. The 115 th Congress has conducted oversight to ensure the requirements in the law are met and the network is deployed as intended. To ensure continued effective oversight, the 115 th Congress may consider requesting more detailed information on the FirstNet network. Details about the network (e.g., network deployment, use of federal funds, use of the spectrum, rural coverage agreements), were contained in the FirstNet/AT&T contract and in state deployment plans; both were deemed proprietary and were not available for public review. A concern for policymakers is that, without details on how the network is being deployed and how federal resources are being used, it will be difficult for Congress to ensure the requirements of the law are being met, and the network is being implemented as intended. Given the federal investment in the project ($6.5 billion and 20 MHz of valuable broadband spectrum, which some experts have valued at $8 billion), and the importance of the FirstNet network to the life of safety of first responders and citizens, congressional oversight of this project is likely to continue. The act requires the network to be self-sustaining, primarily through user fees, but does not require state and local public safety agencies to subscribe. AT&T has offered specialized features and services (e.g., priority access to the network, disaster support) to entice users to the network; however, some agencies have expressed a reluctance to join, citing uncertainties with the network's security, reliability, and resiliency; coverage (rural and non-rural); and costs. Other agencies have expressed a reluctance to join until FirstNet can provide mission critical voice features that will not be available on FirstNet devices until 2019. The 115 th Congress may address subscriptions to the FirstNet network (e.g., offer federal grant funding for equipment or devices), to ensure the network will be sustained and improved over time, as required in the act, and to achieve the intent of the law: to provide a single nationwide interoperable network that will enable all public safety users to communicate and coordinate during emergencies. The establishment of the FirstNet network will not, on its own, resolve the communication issues experienced during September 11, 2001. To operate as intended, state and local public safety agencies will need to subscribe to the FirstNet network; integrate FirstNet capabilities into response plans, procedures, training, and exercises; and use the network regularly to enhance coordination, communication, and response. The 115 th Congress may address public safety agencies that subscribe to the network to integrate FirstNet capabilities into state and local response.

While the national alerting system—the Integrated Public Alert and Warning System (IPAWS)—worked as intended, the roles and responsibilities for issuing alerts for incoming ballistic missiles gained the attention of Congress after this incident. In response to the incident, bills were introduced to redefine roles and responsibilities for issuing alerts for incoming ballistic missiles. The Authenticating Local Emergencies and Real Threats (ALERT) Act of 2018 ( S. 2385 ), and its companion in the House ( H.R. 4965 ) would restrict the authority to alert the public of a missile threat to the federal government. Sponsors of this legislation believe that the federal agencies responsible for detecting incoming missiles (e.g., Department of Defense) should serve as the sole alerting authority for incoming ballistic missiles, to ensure the alert sent is validated at the source, and to reduce the incidence of false alerts. The 115 th Congress may consider the role of DOD in alerting to increase the reliability of the alert, and to increase the trust of citizens in the alerting system. The recent wildfires in California presented different alerting issues. Counties in California used a commercial alerting system (versus IPAWS) that allowed officials to target alerts to county residents. However, the commercial system required residents to sign up for the service. With only a fraction of the residents subscribed, only a fraction received the wildfire alert. County officials considered issuing an alert through the federal IPAWS system, which would have alerted all residents in the area via television, radio, cell phone, social media, etc. However, county officials believed that the wireless emergency alerts (WEA)—cell phone alerts—that are issued through IPAWS could not be targeted to precise regions within the county. Officials feared that issuing a countywide alert would result in the unnecessary evacuation of some citizens, and congestion on evacuation routes. In January 2018, the FCC adopted rules to improve geo-targeting of wireless emergency alerts (WEA). The rules require carriers that participate in the WEA program to deliver WEA alerts in a more geographically precise manner so that the alerts are targeted to the communities impacted by an emergency, as defined by the alert originator (e.g., state or local emergency manager). The FCC required participating providers to reach all of the devices in the target area with not more than a 0.1 mile overshoot. Smaller, rural carriers whose legacy networks may be technically incapable of matching the specified target area are required to deliver the WEA to an area that best approximates the target area. Carriers must comply with these rules by November 30, 2019. Given the variation in alerting methods and capabilities, the 115 th Congress may address state and local investment in training and programs that educate officials and individuals on the various alerts and the appropriate response to different alerts in order to increase preparedness. While wireless emergency alerts are useful during emergencies, in California, where fires destroyed the majority of the communications infrastructure (e.g., towers), all electronic alerting systems would have been rendered useless. The 2018 California wildfires highlighted the need for back-up communications, education of officials on federal alerting capabilities, and the education of citizens on various alerts. The 115 th Congress may address supporting state and local investment in back-up communications, and back-up alerting capabilities in the event that communication systems fail. For Further Information Jill Gallagher, Analyst in Telecommunications Policy CRS In Focus IF10816, Emergency Alerting—False Alarm in Hawaii , by [author name scrubbed] The Internet of Things (IoT) may continue to be a focal point of far-reaching debates during the 115 th Congress. The term refers to networks of objects with two features—a unique identifier and Internet connectivity. Such "smart" objects can form systems that communicate among themselves, usually in concert with computers, allowing automated and remote control of many independent processes and potentially transforming them into integrated systems. Such objects may include vehicles, appliances, medical devices, electric grids, transportation infrastructure, manufacturing equipment, building systems, and so forth. The IoT is increasingly impacting homes and communities, factories and cities, and nearly every sector of the economy, both domestically and globally, among them agriculture (precision farming), health (medical devices), and transportation (self-driving automobiles and unmanned aerial vehicles). An increasing number of these systems require access to radio frequency spectrum in order to connect to the Internet or other networks. The development of fifth-generation (5G) wireless technologies is likely to develop in tandem with the IoT, potentially expanding substantially the opportunities for growth in use of IoT devices. Although the full extent and nature of impacts of the IoT remain uncertain, some economic analyses predict that it will contribute trillions of dollars to economic growth over the next decade. The IoT, for example, may be able to facilitate more integrated and functional infrastructure, especially in "smart cities," through improvements in transportation, utilities, and other municipal services. Sectors that may be particularly affected are agriculture, energy, government, health care, manufacturing, and transportation. The federal government may play an important role in enabling the development and deployment of the IoT, including R&D, standards, regulation, and support for testbeds and demonstration projects. No single federal agency has overall responsibility for the IoT. Various agencies have relevant regulatory, sector-specific, and other mission-related responsibilities, such as the Departments of Commerce, Health, Energy, Transportation, and Defense, the National Science Foundation, the Federal Communications Commission, and the Federal Trade Commission. The range of issues that might be the subject of congressional activity includes the following: security of objects and the systems and networks to which they are connected, given especially that many IoT devices are operational technology, the compromise of which can have physical impacts (see also " Cybersecurity "); privacy of the information gathered and transmitted by objects; standards for the IoT, especially with respect to connectivity; transition to a new Internet Protocol (IPv6) that can handle the anticipated exponential increase in the number of IP addresses required by the IoT, along with the growth of 5G wireless; methods for updating the software used by IoT objects in response to security and other needs; energy management for IoT objects, especially those not connected to the electric grid; and the role of the federal government in development and deployment, standards, regulation, and communications, including the impact of federal rules regarding "net neutrality." The Internet of Things represents more than devices connected through networks, and more than Internet or radio frequency spectrum policy. Its growth will likely require significant changes in—and coordination among—many government departments and agencies.

Some technological advances have arguably opened a treasure trove of information for investigators and analysts. Others have presented unique hurdles. While some feel that law enforcement now has more information available to them than ever before, others contend that law enforcement is "going dark" as their investigative capabilities are outpaced by the speed of technological change. These hurdles for law enforcement include strong, end-to-end (or what law enforcement has sometimes called "warrant-proof") encryption; provider limits on data retention; bounds on companies' technological capabilities to provide specific data points to law enforcement; tools facilitating anonymity online; and a landscape of mixed wireless, cellular, and other networks through which individuals and information are constantly passing. As such, law enforcement cannot access certain information they otherwise may be authorized to obtain. The tension between law enforcement capabilities and technological change has received congressional attention for several decades. For instance, in the 1990s the "crypto wars" pitted the government against technology companies, and this tension was highlighted by proposals to build in vulnerabilities, or back doors, to certain encrypted communications devices as well as to restrict the export of strong encryption code. In addition, Congress passed the Communications Assistance for Law Enforcement Act (CALEA; P.L. 103-414 ) in 1994 to help law enforcement maintain their ability to execute authorized electronic surveillance as telecommunications providers turned to digital and wireless technology. The "going dark" debate originally focused on data in motion, or law enforcement's ability to intercept real-time communications. However, more recent technology changes have impacted law enforcement's capacity to access not only communications but stored content, or data at rest. Some officials have urged the technology community to develop a means to assist law enforcement in accessing encrypted data. At the same time, law enforcement entities have taken steps to bolster their technology capabilities. In addition, policymakers have been evaluating whether legislation may be an appropriate response to the problems posed by encryption. For Further Information Kristin M. Finklea, Specialist in Domestic Security CRS Report R44481, Encryption and the "Going Dark" Debate , by [author name scrubbed] CRS Report R44642, Encryption: Frequently Asked Questions , by [author name scrubbed] Congress passed the High-Performance Computing and Communications Program (HPCC) Act of 1991 ( P.L. 102-194 ) to enhance the effectiveness of federally funded information technology (IT) R&D programs and to encourage coordination among agencies conducting such research. Proponents of federal support of IT R&D assert that it has produced positive outcomes for the country and played a crucial role in supporting long-term research into fundamental aspects of computing. Such fundamentals may provide broad practical benefits, but generally take years to realize. Additionally, the unanticipated results of research are often as important as the anticipated results. Another aspect of government-funded IT research is that it often leads to open standards, something that many perceive as beneficial, encouraging deployment and further investment. Industry, on the other hand, is more inclined to invest in proprietary products and will diverge from a common standard when there is a potential competitive or financial advantage to do so. Supporters believe that the outcomes achieved through the various funding programs create a synergistic environment in which both fundamental and application-driven research are conducted, benefitting government, industry, academia, and the public. Critics, however, assert that the government, through its funding mechanisms, may be picking "winners and losers" in technological development, a role more properly residing with the market. For example, the size of the Networking and Information Technology Research and Development (NITRD) Program may encourage industry to follow the government's lead on research directions rather than selecting those directions itself. The NITRD Program is funded through appropriations to its individual agencies, so support for it will likely be part of the federal budget debate in Congress.

The National Science Foundation (NSF) supports basic research and education in the non-medical sciences and engineering and is a primary source of federal support for U.S. university research. It is also responsible for significant shares of the federal science, technology, engineering, and mathematics (STEM) education program portfolio and federal STEM student aid and support. Enacted funding for NSF in FY2018 was $7.767 billion. The NSF's funding levels and congressional direction of funding have been long-standing issues of congressional interest. At various points in NSF's history, some policymakers have pursued a policy of authorizing large increases in the NSF budget over a defined period of time (e.g., a 100% increase over seven years, sometimes referred to as a "doubling path policy"). Actual appropriations have rarely reached authorized levels, and growth in NSF's budget has slowed in recent years. Advocates of large funding increases assert that steep and fast increases in NSF funding are necessary to ensure U.S. competitiveness. Other analysts argue that steady, reliable funding increases over longer periods of time would be less disruptive to the U.S. scientific and technological enterprise. Alternatively, some policymakers seek no additional increases in NSF funding in light of the federal deficit and spending caps. Additionally, some policymakers prefer to direct federal funding to research with a more applied or mission-oriented focus than that which is typically funded at NSF. Policy issues of particular interest that the 115 th Congress may continue to address include the selection, funding, and management of large-scale construction projects, scientific instruments, and facilities, including the use of management fees and the construction of new large research vessels; the foundation's grant-making process, including its peer review process; and the effectiveness and costs of NSF's use of non-federal personnel—through the Intergovernmental Personnel Act (IPA) program—often called "rotators." Further, analysts and legislators have periodically debated questions about prioritizing NSF funding for the physical sciences and engineering over funding for the social, behavioral, and economic sciences, as well as expanding support for multidisciplinary funding. Other lasting federal policy issues for the NSF focus on the balance between scientific independence and accountability to taxpayers; the geographic distribution of grants; NSF's role in broadening participation in STEM fields; support for various STEM education programs; and the production of data about the U.S. scientific and technological enterprise. For Further Information [author name scrubbed], Analyst in Science and Technology Policy CRS Report R45009, The National Science Foundation: FY2018 Appropriations and Funding History , by [author name scrubbed] Nanoscale science, engineering, and technology—commonly referred to collectively as nanotechnology—is believed by many to offer extraordinary economic and societal benefits. Nanotechnology R&D is directed toward the understanding and control of matter at dimensions of roughly 1 to 100 nanometers (a nanometer is one-billionth of a meter). At this size, the properties of matter can differ in fundamental and potentially useful ways from the properties of individual atoms and molecules and of bulk matter. Many current applications of nanotechnology are evolutionary in nature, offering incremental improvements in existing products and generally modest economic and societal benefits. For example, nanotechnology is being used in automobile bumpers, cargo beds, and step-assists to reduce weight, increase resistance to dents and scratches, and eliminate rust; in clothes to increase stain- and wrinkle-resistance; and in sporting goods to improve performance. Other nanotechnology innovations play a central role in current applications with substantial economic value. For example, nanotechnology is a fundamental enabling technology in nearly all semiconductors and is key to improvements in chip speed, size, weight, and energy use. Similarly, nanotechnology has substantially increased the storage density of non-volatile flash memory and computer hard drives. In the longer term, some believe that nanotechnology may deliver revolutionary advances with profound economic and societal implications, such as detection and treatment of cancer and other diseases; clean, inexpensive, renewable power through energy transformation, storage, and transmission technologies; affordable, scalable, and portable water filtration systems; self-healing materials; and high-density memory devices. The development of this emerging field has been fostered by sustained public investments in nanotechnology R&D. In 2001, President Clinton launched the multi-agency National Nanotechnology Initiative (NNI) to accelerate and focus nanotechnology R&D to achieve scientific breakthroughs and to enable the development of new materials, tools, and products. More than 60 nations subsequently established programs similar to the NNI. Through FY2017, Congress has appropriated approximately $23.4 billion for nanotechnology R&D; the President requested $1.2 billion in FY2018 funding. In 2003, Congress enacted the 21 st Century Nanotechnology Research and Development Act ( P.L. 108-153 ), providing a legislative foundation for some of the activities of the NNI, establishing programs, assigning agency responsibilities, and setting authorization levels through FY2008. Legislation has been introduced in the 114 th and 115 th Congress to amend and reauthorize the act though none has been enacted into law. Congress has directed its attention primarily to three topics that may affect the realization of nanotechnology's hoped-for potential: R&D funding; U.S. competitiveness; and environmental, health, and safety (EHS) concerns. For Further Information [author name scrubbed], Specialist in Science and Technology Policy CRS Report RL34511, Nanotechnology: A Policy Primer , by [author name scrubbed] CRS Report RL34401, The National Nanotechnology Initiative: Overview, Reauthorization, and Appropriations Issues , by [author name scrubbed] CRS Report RL34614, Nanotechnology and Environmental, Health, and Safety: Issues for Consideration , by [author name scrubbed] Congress has historically had a strong interest in space policy issues. Space topics that may come before the 115 th Congress include the funding and oversight of the National Aeronautics and Space Administration (NASA) and issues related to the commercialization of space and to Earth-observing satellites. Spaceflight has attracted strong congressional interest since the establishment of NASA in 1958. Issues include the goals and strategy of NASA's human spaceflight program, the impact of constrained budgets on NASA's other missions, and the future of NASA's Earth Science program. In its first session, the 115 th Congress enacted the NASA Transition Authorization Act of 2017 ( P.L. 115-10 ). In the second session, it is continuing to address NASA reauthorization legislation. With the end of the space shuttle program in July 2011, the United States lost the capability to launch astronauts into space. Since that time, NASA has relied on Russian spacecraft for crew transport to the International Space Station (ISS). For ISS cargo transport, NASA-contracted U.S. commercial flights have been delivering payloads of supplies and equipment since October 2012. As directed by the NASA Authorization Act of 2010 ( P.L. 111-267 ), NASA is pursuing a two-track strategy for human spaceflight. First, for transport to low Earth orbit, including the ISS, NASA is supporting commercial development of a crew transport capability like the commercial cargo capability achieved in 2012. Commercial crew transportation services are likely to become operational in 2019. Second, for human exploration beyond Earth orbit, NASA is developing a new crew capsule called Orion and a new heavy-lift rocket called the Space Launch System (SLS). The first crewed test flight of Orion and the SLS is scheduled for 2023. Most details of the subsequent exploration missions of Orion and the SLS remain to be determined. In February 2018, NASA announced plans for a Lunar Orbital Platform–Gateway (LOP-G) in lunar orbit, to be accessed via Orion and the SLS, that would serve as a platform for deep-space human exploration. Rapid developments in the commercial space sector may change the relationship between NASA and industry. For example, SpaceX has announced plans for commercial flights carrying passengers around the Moon and back as well as, in the longer term, to Mars. Some observers see this sort of development as potentially competing with NASA's human spaceflight plans. More broadly, the emergence of new commercial capabilities in space may present NASA with new opportunities for public-private partnerships or may shift its R&D priorities. For example, NASA has announced plans to end direct funding for the International Space Station by 2025, instead relying on a combination of public-private partnerships and commercial service contracts. The 2010 authorization act authorized funding increases for NASA that were not subsequently appropriated. In considering reauthorization, the 115 th Congress may examine whether reduced budget expectations require corresponding changes to planned programs. One common concern is that the cost of planned human spaceflight activities may mean less funding for other NASA missions, such as unmanned science satellites, aeronautics research, and space technology development. NASA's Earth Science program, in which climate research is a major focus, is of particular congressional interest. Some in Congress have argued that other NASA activities should have higher priority or that some or all of NASA's Earth Science responsibilities should be transferred to other agencies. Supporters counter that space-based Earth observations are an integral part of NASA's science mission.

While U.S. government purchases provided much of this market, about one quarter of sales were within the commercial sector. Although the commercial space industry has existed for several decades, some observers have identified an emerging "new space" sector of relatively new companies focused on private spaceflight at low cost. One factor driving this trend is NASA's reliance on commercial providers for access to the ISS, but "new space" companies are also focused on other markets. These include the launch of national security satellites for the Department of Defense, the launch of commercial satellites for U.S. and foreign companies, and even space tourism. The Federal Aviation Administration (FAA) licenses commercial space launch and reentry, including commercial spaceports. As part of the FAA licensing process, the federal government indemnifies launch providers against certain third-party liabilities. The U.S. Commercial Space Launch Competitiveness Act ( P.L. 114-90 ) extended this indemnification policy (for the ninth time since 1988) through September 2025. The act also extended through September 2023 a statutory moratorium that restricts the FAA's authority to regulate the safety of crewed spaceflight. The status of human spaceflight safety regulations has been a focus of recent congressional interest because of NASA's plans for commercial crewed flights to the ISS. Several other federal agencies are also involved in the commercial space industry. The National Oceanographic and Atmospheric Administration (NOAA) licenses commercial remote sensing satellites. The Federal Communications Commission licenses the use of radio frequencies by commercial satellites and assigns locations for satellites in geostationary orbits. The National Transportation Safety Board investigates certain spacecraft accidents. The Department of Commerce Office of Space Commerce supports and promotes U.S. space commerce. Oversight of export controls on most aspects of commercial satellites shifted from the Department of State to the Department of Commerce in 2014. In February 2018, the National Space Council made recommendations for regulatory reforms at multiple agencies. Some of those recommendations are likely to result in legislative proposals from the Administration in 2018 and 2019. In response or on its own initiative, the 115 th Congress is likely to continue to address the commercial space regulatory and oversight framework.

Satellite observations of the Earth's oceans and land surface help with short-term seasonal forecasts of El Niño and La Niña conditions, which are valuable to U.S. agriculture and commodity interests; identification of the location and size of wildfires, which can assist firefighting crews and mitigation activities; as well as long-term observational data of the global climate, which are used in predictive models that help assess the degree and magnitude of current and future climate change. Congress continues to be interested in the performance of NASA, NOAA, and the U.S. Geological Survey in building and operating U.S. Earth-observing satellites. Congress has been particularly interested in the agencies meeting budgets and time schedules so that critical space-based observations are not missed due to delays and cost overruns. Concerns have been raised in the past by Congress about the possibility of a "data gap" in the polar-orbiting weather satellite coverage. The successful launch of the first Joint Polar Satellite System satellite JPSS-1 (now NOAA-20) on November 18, 2017, has alleviated those concerns for the near-term. Congress provided full funding, about $776 million for the second polar-orbiting satellite, JPSS-2, in the FY2018 enacted appropriations. NOAA's program for future polar-orbiting weather satellites, the Polar Follow-On mission, is likely to be more controversial both within Congress and in the Trump Administration. On November 19, 2016, the GOES-R (Geostationary Operational Environmental Satellite-R) weather satellite launched and was placed into orbit. Renamed GOES-16, it is an advanced weather satellite with sensors that should help improve hurricane tracking and intensity forecasts, prediction and warning of severe weather events, and rainfall estimates that will lead to better flood warnings. GOES-16 also carries the first operational lightning mapper in geostationary orbit, and will better monitor space weather—perturbations to the Earth's magnetic field caused by intense bursts of energy from the sun. On March 1, 2017, GOES-S successfully launched carrying the same suite of instruments as its predecessor. Both satellites represent the first two in a series of four Earth-orbiting weather satellites planned by NOAA through 2036.

Summary: Science and technology (S&T) have a pervasive influence over a wide range of issues confronting the nation. Public and private research and development spur scientific and technological advancement. Such advances can drive economic growth, help address national priorities, and improve health and quality of life. The constantly changing nature and ubiquity of science and technology frequently create public policy issues of congressional interest. The federal government supports scientific and technological advancement directly by funding and performing research and development and indirectly by creating and maintaining policies that encourage private sector efforts. Additionally, the federal government establishes and enforces regulatory frameworks governing many aspects of S&T activities. This report briefly outlines an array of science and technology policy issues that may come before the 115th Congress. Given the rapid pace of S&T advancement and its importance in many diverse public policy issues, S&T-related issues not discussed in this report may come before the 115th Congress. The selected issues are grouped into 10 categories: Overarching S&T Policy Issues, Agriculture, Biomedical Research and Development, Defense, Energy, Environment and Natural Resources, Homeland Security, Information Technology, Physical and Material Sciences, and Space. Each of these categories includes concise analysis of multiple policy issues. The material presented in this report should be viewed as illustrative rather than comprehensive. Each section identifies CRS reports, when available, and the appropriate CRS experts to contact for further information and analysis.
