[Q]: Paragraph: Analysis of powdered samples drilled out from inside an ancient and once water-soaked rock at the rover's Gale Crater landing site show clays, sulfates and other minerals that are all key to life, scientists told reporters at NASA headquarters in Washington and on a conference call on Tuesday. The water that once flowed through the area, known as Yellowknife Bay, was likely drinkable, said Curiosity's lead scientist John Grotzinger, who is with the California Institute of Technology. The analysis stopped short of a confirmation of organics, which are key to most Earth-like life. But with 17 months left in the rover's primary mission, scientists said they expect to delve further into that question. Science operations currently are suspended because of a computer glitch, which is expected to be resolved this week. Whether or not Mars has or ever had life, it should have at one time at least had organic compounds delivered to its surface by organic-rich comets and asteroids. Finding places where the organics could have been preserved, however, is a much trickier prospect than finding the environmental niches and chemistry needed to support life, scientists said. In May, following a one-month interruption of radio communications caused by the positions of Earth and Mars, scientists plan to drill a second hole into the Gale Crater rock to look for organic compounds. "If there was organic material there, it could have been preserved," said David Blake, principal investigator for Curiosity's Chemistry and Mineralogy, or CheMin, experiment. A lack of organics, however, would not rule out the Yellowknife Bay site as suitable for life, scientists added. "You don't have to have carbon present in a geological environment that's habitable in order to have microbial metabolism occur," Grotzinger said. Some micro-organisms on Earth, for example, can feed on inorganic compounds, such as what are found inside rocks. "There does need to be a source of carbon somewhere, but if it's just CO2 (carbon dioxide), you can have chemoautotrophic organisms that literally feed on rocks and they will metabolize and generate organic compounds based on that carbon," Grotzinger said. Analysis shows the Gale Crater rock contains carbon dioxide, in addition to hydrogen, oxygen, phosphorus, sulfur and nitrogen. Carbon dioxide provides a key ingredient in the building blocks for life, all of which have now been found in the Mars rock sample, Grotzinger said. The $2.5 billion, nuclear-powered Curiosity rover landed inside the giant Gale Crater impact basin, located near the Martian equator, on August 6 for a two-year mission. Scientists were drawn to the area because of a three-mile (5-km) mountain of sediment, called Mount Sharp, rising from the crater floor. But shortly after the rover's landing, the team decided to first explore the Yellowknife Bay area, located in the opposite direction from Mount Sharp. Observations from Mars orbiters showed three different types of terrain coming together in Yellowknife Bay, plus a low elevation, all hints that water could have once flowed and pooled on the surface. That hunch was verified with the first chemical analysis of material drilled out from inside what appears to be a slab of bedrock, named John Klein, after a mission manager who died in 2011. Scientists don't know the rock's age, nor how it formed. They suspect, however, that the John Klein rock is at least 3 billion years old and that it spent enough time in non-acidic and not-too-salty water for various telltale clays and minerals to form. "This rock, quite frankly, looks like a typical thing that we would get on Earth," Grotzinger said. "The key thing here is this is an environment that microbes could have lived in and maybe even prospered in." The habitable conditions in Yellowknife Bay appear to roughly coincide within a couple of hundred million years of the first evidence for life on Earth. "On Earth, finding organics in very, very ancient rocks is a difficult proposition," said Paul Mahaffy, principal investigator for Curiosity's Sample Analysis at Mars, or SAM, instrument. Finding organics on Mars may be even more challenging. Without much protection from an atmosphere, ultraviolet and cosmic radiation can destroy organics. Mars also apparently is covered with chemicals, known as perchlorates, that consume organics. "The search for organic carbon is an issue for this mission and you want to do this as deliberately as possible. You don't just want to wander around and try stuff out," Grotzinger said. Knowing that Mars at least had the ingredients for life, however, makes the search for organics more viable. "This is not a simple problem, but I think the mission is up to it and we're really excited to get started on that now," Grotzinger said. Claim: Mars had the right stuff for life, scientists find.
[A]: Seven months after NASA's rover Curiosity landed on Mars to assess if the planet most like Earth had the ingredients for life, scientists have their answer: Yes.

[Q]: Paragraph: WellPoint, which released lower fourth-quarter results on Wednesday, said that based on age, insurance plan selection, income levels, gender and available pharmacy data, it believes it has set the right premium rates for these new customers. Insurance plans under President Barack Obama's healthcare reform law went on sale October 1 and into effect on January 1. Initial enrollment data nationwide has shown that the first wave of people who enrolled are older people who can be more expensive to insure because they often have more health problems than young people. Shares in WellPoint rose about 3 percent, or $2.75, to $87.05 in morning trading after the comments. Competitor Aetna Inc shares rose 39 cents to $69.32 while UnitedHealth Group Inc gained 33 cents to $72.03. "There was a concern that a lot of the firms that were involved in the exchanges would be underpriced for the demographic that would find the exchanges appealing, at least over the first year," Morningstar analyst Vishnu Lekraj said. "What they said was that they priced everything appropriately given the data they have currently, in terms of medical cost utilization," Lekraj said. WellPoint, one of the biggest players on the exchanges, said that it was still not certain about how enrollment, which is open until March 31, would finally end up, contributing to uncertainty about its 2014 earnings. The company forecast earnings of above $8 per share in 2014, representing a likely drop from the $8.52 it earned in 2013 before special items. Analysts on average were expecting 2014 earnings to fall to $8.39 per share, according to Thomson Reuters I/B/E/S. Chief Financial Officer Wayne DeVeydt said the 2014 outlook reflects about a $100 million negative effect of changes in government policy regarding the rollout of Obamacare. Late last year as political pressure mounted around technology problems on the exchanges and the higher premium rates on new plans, the Obama administration said that older individual plans could be renewed and it increased the number of people eligible for catastrophic coverage. DeVeydt said ACA insurer fees, which are not tax deductible for insurers, would cost earnings $1.10 per share and that it would spend about $30 million on first-year exchange costs. FOURTH-QUARTER PROFIT FALLS WellPoint said fourth quarter profit fell as consumers increased their use of medical services ahead of the cancellation of some insurance plans at the end of 2013. The company also took a charge for the recently announced sale of its contact lens business, 1-800 Contacts, to private equity firm Thomas H. Lee Partners, which caused a sharp decline in net profit. WellPoint, which sells Empire and Anthem Blue Cross Blue Shield plans, also said its costs went up as it prepared for the rollout of Obamacare, and an expected increase of 1 million new members this year. So far, about 3 million people have enrolled in exchange plans, according to the government. The Congressional Budget Office had forecast that about 7 million people would sign up for 2014 coverage. Sign-ups are lagging targets because of technology problems in the first two months after the launch of the national website HealthCare.gov that sells insurance plans in 36 states. The other 14 states run their own sites. WellPoint said it had received 500,000 applications for new individual health plans that went into effect January 1, most of them for exchange-based plans but some for plans it sells off the exchange. Income-based subsidies from the government are only available for exchange plans. It said most of these customers were new to WellPoint. WellPoint said net profit for the fourth quarter fell to $148.2 million, or 49 cents per share, from $464 million, or $1.51 per share a year earlier. Excluding costs for the sale of 1-800 Contacts and investment gains, earnings fell to 87 cents per share from $1.03 per share, which also included investment gains and acquisition costs. The quarterly earnings were in line with analyst expectations, according to Thomson Reuters I/B/E/S. The company spent 87.8 percent of its premiums brought in on medical claims, up from 87.3 percent a year ago. It said that as old individual plans were being canceled ahead of the introduction of the new 2014 insurance, customers used more medical services. Spending on medical procedures, doctor visits and hospitalizations has been at a historical low for the past several years. This has helped insurers keep these medical cost ratios down while still complying with the Affordable Care Act, which requires them to spend at least 80 percent of plan premiums on care or refund customers the difference. WellPoint said it added 145,000 members during the quarter as it picked up small business customers and new enrollees in the California Medicaid program for the poor. It had 35.7 million members at the end of 2013. Claim: WellPoint says health exchange applicants hit expectations.
[A]: U.S. health insurer WellPoint Inc said on Wednesday the applicants for the new Obamacare health plans are of the age and demographics it had expected, indicating that medical costs will not soar beyond the prices it charges.

[Q]: Paragraph: The story mentions that the Internet-based program is a "low-cost" option for treating insomnia; however, nothing more specific regarding cost is provided. It is presumed that the site will be proprietary; if so, what are the expected usage fees? The story states that compared to the control group, the treatment group woke up fewer times, spent fewer minutes awake, and had an improved score; however, the reader is not given any quantitative data or context to determine if these improvements are really meaningful in a person's life. The story does not mention any possible harms that may be associated with managing insomnia via an Internet-based program. For example, might people develop worsening insomnia because of reinforcement of bad habits? A comment regarding the lack of identifiable harms would have been sufficient. The story accurately described the methodology and the participants; although this could have been further improved by providing more information about the control group, namely, that they did receive any type of treatment for insomnia. Additionally, the story effectively conveyed that this was a small study with a fairly homogenous population. This story does not directly address the prevalence of insomnia, but the overall tone does not suggest disease-mongering. This story includes comments from two independent experts, as well as a study co-author. The writer also mentions that the study was funded by a grant from the National Institute of Mental Health. This story includes information on the benefits of cognitive behavioral therapy and working with a therapist for treating insomnia and briefly mentions sleep medications. The story states that this Internet-based program "could one day" be an option for treating insomnia, which suggests that it is not yet ready for prime time. The story conveyed that this is a novel treatment modality for insomnia. The story does not appear to rely on a press release and quotes multiple sources that appear to be from interviews. Claim: Internet-based therapy shows promise for insomnia
[A]:
This was a generally well written and balanced story about a small exploratory study on a possible new therapy for insomnia. The story effectively describes the methodology and patient population and includes expert commentary from independent sources. The story also appropriately cautions that larger studies with a more diverse patient population are warranted to verify the results and determine their generalizability. While the story meets many of our criteria, it would have been greatly improved by providing the reader with quantitative data and some context to help determine if the results translated to any real, meaningful benefit in peoples' lives. For example, information on the Insomnia Severity Index, which was used to measure efficacy of the Internet-based program, would have been helpful. A brief exploration of cost, and of any potential harms (or lack of), would also have substantially strengthened the piece.
