PROBLEM: Paragraph: After nearly disappearing in the United States, the bloodsucking pests have made a comeback in recent years, quickly infesting apartment buildings and stubbornly resisting common insecticides. The city of New York alone spends as much as $40 million a year in bedbug control. A study of bedbug genetics presented on Tuesday at the American Society of Tropical Medicine and Hygiene meeting in Philadelphia now suggests why. A team of entomologists led by Coby Schal and Ed Vargo of North Carolina State University studied the genes of bedbugs infesting three multistory apartment buildings in North Carolina and New Jersey and found very low genetic diversity — meaning most of them were very close relatives. They were so close in fact that the team suspects it may have taken just one or two founder insects to start an entire infestation. “We find that bedbug infestations basically start from a very small number of individuals,” Schal said in a telephone interview. “A single mated female bedbug starts the infestation. She gives rise to offspring and those offspring mate with each other and with their mother,” he said. “This is different from many animals,” he said, mostly because close inbreeding can result in genetic deformities, adding, “In humans, it is taboo.”   But he said there are some animals that can withstand such close inbreeding without experiencing detrimental effects including cockroaches. Schal said this may be a trait of insects that have evolved an association with humans and rely on them to get from place to place. Typically this happens when humans bring infested furniture into their homes, and he warns people to inspect second-hand furniture carefully. “There is a myth out there that bedbugs get transported on people,” Schal said. Unlike ticks, the wingless, reddish-brown insects stay attached to people for a blood meal for just 5 to 10 minutes, he said. “The chances that a person is carrying bedbugs on them is quite low.”   According to the U.S. Centers for Disease Control and Prevention, bedbugs do not carry disease, but their bites can cause severe itching and a whole lot of anxiety. Schal said his findings are not likely to lead to new insecticides for bedbugs, but they do underscore the need to move fast once bedbugs are detected. “If you don’t deal with them early they can spread thorough   a building very quickly,” he said. Claim: All in the family: Inbreeding key to bedbug spread.

SOLUTION: Inbreeding may be the secret to the bedbug’s success, U.S. researchers said on Tuesday.

PROBLEM: Paragraph: NCR Corp. will fund the dredging of contaminated sediments and removal of an aging dam in the Kalamazoo River under an agreement with the U.S. Environmental Protection Agency, the U.S. Department of Justice and the state of Michigan, officials told The Associated Press ahead of an official announcement. “This is a big step forward toward cleaning up the river,” said John Irving, a deputy assistant administrator in the EPA’s Office of Enforcement and Compliance Assurance. The Kalamazoo is polluted with polychlorinated biphenyls, or PCBs, from paper recycling mills. Used for ink removal, the chemicals were discharged into the river from the 1950s through the mid-1970s. They also seeped into groundwater and surface waters from landfills where mill waste was dumped. In addition to the river, the contamination zone in Allegan and Kalamazoo counties includes a roughly 3-mile (5-kilometer) section of a tributary called Portage Creek, as well as mill properties, riverbanks and floodplains. It is on the federal Superfund list of hazardous sites. Signs posted along the river warn anglers not to eat the fish they catch. The EPA has overseen the removal of nearly 450,000 cubic yards (344,000 cubic meters) of soil and sediment from the area since 1998, in addition to cleaning up 7 miles (11 kilometers) of the river and riverbanks. Eighty-two acres (33 hectares) of landfills containing PCBs have been covered with layers of clay, topsoil and vegetation to prevent the toxins from leaching into groundwater. But much remains to be done. The agreement between NCR and the government calls for the company to pay at least $135.7 million for cleanup work that is expected to take an additional 10-15 years. Among the tasks: dismantling Trowbridge Dam in Allegan County. The dam, which was built in 1898 to supply electric power to Kalamazoo, is in poor shape and has been over-topped by high water. It is the highest-priority dam removal planned in Michigan, according to the state Department of Natural Resources, which set aside $2.9 million in May to get the project underway. The first step is to stabilize the structure so that it won’t collapse while a contractor dredges PCB-laced sediments from a 2.4-mile (3.9-kilometer) river section upstream, which is expected to take three years, said Paul Ruesch, the EPA’s on-site coordinator. NCR funds will pay for that work and for razing the dam when the sediment removal is complete, Assistant U.S. Attorney General Jeffrey Bossert Clark told the AP. “You want to get that sediment out before taking the dam out, so you’re not letting the sediments wash further downstream,” he said. The removal of tainted soils in several floodplain spots is also funded under the deal. And the company will also pay $76.5 million to the EPA to cover past and future costs of the river cleanup; $27 million to other federal and state agencies for damages to natural resources; and $6 million to the state for past and future costs. The proposed settlement was filed in federal court Wednesday. The public will get 30 days to comment, after which the government agencies could make revisions before requesting final court approval. NCR spokesman Scott Sykes said the company had no comment. The agreement represents a significant milestone in the overall cleanup, which is expected to end up costing about $851 million, Clark said. Payment negotiations are continuing with other companies that share responsibility for the pollution, including Georgia-Pacific, International Paper and Weyerhaeuser. The Kalamazoo River project is among those on the Superfund list designated by the Trump administration for special attention because of cleanup delays, Irving said. “This settlement represents substantial progress in the cleanup and restoration of the Kalamazoo River,” said Liesl Clark, Director of the Michigan Department of Environment, Great Lakes and Energy. In addition to protecting public health and the environment, she said, it will fund “projects to restore natural resources and help compensate the public for lost recreational opportunities within this important Southwest Michigan watershed.” While “extremely welcome,” the deal won’t raise enough money to finish the cleanup and agencies should continue pressing the polluters to do more, said Kenneth Kornheiser, president of the Kalamazoo River Watershed Council, a nonprofit advocacy group. “I appreciate the monumental size of the problem, but somebody created the problem and needs to be responsible for remediating the damage,” he said. ___ Follow John Flesher on Twitter: https://twitter.com/johnflesher Claim: Company to pay $245M toward cleanup of Kalamazoo River PCBs.

SOLUTION: One of the companies responsible for polluting an 80-mile (129-kilometer) stretch of river and floodplains in southwestern Michigan with toxic chemicals will pay at least $245.2 million to advance a cleanup effort that began more than 20 years ago, federal officials said Wednesday.

PROBLEM: Paragraph: "One theme Sen. Bernie Sanders has repeatedly touched on during his run for the Democratic nomination for president has been the high cost of prescription drugs. His comment during the Feb. 11 Democratic debate at the University of Wisconsin-Milwaukee was typical as he rattled off a list of problems with the U.S. health care system: ""In America, we pay, by far, the highest prices in the world for prescription drugs."" We asked the Sanders campaign for the source of his claim. We didn't get a response. So we searched on our own. One organization that tracks such things is the International Federation of Health Plans, based in London. Their latest price report, from 2013, lists eight common drugs. Compared with England, the Netherlands, Spain, Switzerland and Canada, U.S. prices were far higher, sometimes dramatically so. Consider Nexium, the medicine widely used to treat acid reflux. A prescription that would cost $60 or less in other countries costs, on average, $215 in the United States. And that's just the average. Prices vary widely in this country: In 5 percent of the cases, the cost was $395. ""What Bernie says is true. There's nowhere that pays the same price as America,"" said Tom Sackville, the federation's CEO. In addition, ""there is this huge variation in price across America. Anything above the average is quite unjustified. When you get up to the 95th percentile, you're talking grand robbery."" The findings were similar in an April 2013 study published in the journal Health Affairs, which looked at the prices of brand name drugs in the United States, United Kingdom, Switzerland, Germany, France, Canada and Australia. In each of the three years studied -- 2005, 2007 and 2010 -- U.S. prices were consistently higher. The one exception: Switzerland. In addition, researchers found that, between 2005 and 2010, ""the gap between the United States and other countries seemed to widen."" And it wasn't just new drugs being embraced first in the United States that was driving up costs. They concluded that ""prices for older products rose faster in the United States than in other countries."" But Joel Farley of the University of North Carolina at Chapel Hill's Eshelman School of Pharmacy cautioned that the rule doesn't always apply to generic drugs. A 2008 comparison of 19 generic drugs found that some U.S. prices were lower than Canadian prices. ""In some cases it has to do with availability,"" he said. In other cases, a country may set the drug price low and in that fixed-price market ""there's no incentive to go lower."" The Wall Street Journal published an analysis in December that concluded 98 percent of 40 top branded drugs were more expensive in the United States than in England. In Norway, 93 percent of the 40 top branded drugs cost less than in the United States. And in Ontario, a comparison of 30 drugs showed that U.S. prices were also higher for 93 percent of the products. Why are the brand name prices so much lower in other countries, and why is there so much variation in the United States? Big customers can negotiate big discounts. So the countries with socialized medicine have a lot of leverage at the negotiating table, the experts told us. In the United States, hospitals, wholesalers and insurance companies all do their own negotiations. The Veterans Administration can -- and does -- negotiate dramatically lower prices. Under Medicaid, the drug companies are required to provide their medicines at a price that's as low as it is for any of their regular customers. But Medicare has been prohibited by law from negotiating lower prices since 2006, and that's a huge chunk of the U.S. health care industry. (When Barack Obama was first running for president, he promised to repeal that Bush-era restriction, but then backed off in an attempt to get passage of the Affordable Care Act.) The pharmaceutical industry says it needs the extra income to pay for research to keep new, desperately needed drugs coming. But with everyone getting a bargain, Americans are financing that research for the rest of the world, experts told us. Yet there's another way to look at the issue, said Amitava Dasgupta, a clinical toxicologist at the University of Texas Health Science Center at Houston. The tablet that costs a dollar in the United States may only cost 20 cents in India, but that drug is far more expensive to the average person in India because their income is so much lower. ""The U.S. subsidizes research for the world,"" he said. ""But I would look at that as philanthropy."" Our ruling Sanders said, ""In America, we pay, by far, the highest prices in the world for prescription drugs."" When it comes to brand-name drugs, which yield the highest profit for the pharmaceutical industry, studies support Sanders' claim -- although not always on a drug-by-drug basis. In addition, the differences in price can be dramatic because the U.S. health care system is so splintered, and Medicare is prohibited by law from using its market share to bargain for lower prices. We found one study comparing the United States and Canada that found exceptions for generic drugs, where the profit margin is much lower and which make up a much smaller share of prescription drug spending. But on balance," Claim: In America, we pay, by far, the highest prices in the world for prescription drugs.
