WASHINGTON (AP) — Winter hit U.S. honeybees hard with the highest loss rate yet, an annual survey of beekeepers showed.The annual nationwide survey by the Bee Informed Partnership found 37.7% of honeybee colonies died this past winter, nearly 9 percentage points higher than the average winter loss.The survey of nearly 4,700 beekeepers managing more than 300,000 colonies goes back 13 years and is conducted by bee experts at the University of Maryland, Auburn University and several other colleges.Beekeepers had been seeing fewer winter colony losses in recent years until now, said Maryland's Dennis vanEngelsdorp, president of the bee partnership and co-author of Wednesday's survey."The fact that we suddenly had the worst winter we've had ... is troubling," vanEngelsdorp said.Some bees usually die over winter, but until the past couple decades, when a combination of problems struck colonies, losses rarely exceeded 10%, he said.Bees pollinate billion worth of U.S. food crops. One-third of the human diet comes from pollinators, including native wild bees and other animals, many of which are also in trouble, according to the U.S. Department of Agriculture."We should be concerned on multiple levels," said University of California, Berkeley, agricultural social scientist Jennie Durant, who has a separate study this week on loss of food supply for bees.Year-to-year bee colony losses, which include calculations for summer, were 40.7%, higher than normal, but not a record high, the survey found."The beekeepers are working harder than ever to manage colonies but we still lose 40-50% each year... unacceptable," Swiss bee expert Jeff Pettis, who wasn't part of the survey, said in an email.For more than a decade, bees have been in trouble with scientists blaming mites, diseases, pesticides and loss of food.This past winter's steep drop seems heavily connected to the mites, vanEngelsdorp said. Beekeepers report that chemicals that kill mites don't seem to be working quite as well and mite infestation is worsening, he said. Those mites feed on the bees' fats and that's where the insects store protein and center their immune response.Durant's study in this week's journal Land Use Policy found that changes in food supply in the Midwest's Prairie Pothole Region, a hot spot for honeybee colonies, has been a major factor in losses. That area has lost wetland areas with clover bees feed on.Other areas have been converted to corn and soy crops, which don't feed bees, she said.As bad as the survey numbers are, vanEngelsdorp said, "We're not really worried about honeybees going extinct... I'm more worried that the commercial beekeepers will go out of business." 2695

WASHINGTON (AP) — President Donald Trump is threatening to veto a defense policy bill unless it ends protections for internet companies that shield them from being held liable for material posted by their users.Trump tweeted Tuesday that Section 230 of the 1996 Communications Decency Act is “a serious threat to our National Security & Election Integrity.”He adds that if it “is not completely terminated as part of the National Defense Authorization Act (NDAA), I will be forced to unequivocally VETO the Bill.”.....Therefore, if the very dangerous & unfair Section 230 is not completely terminated as part of the National Defense Authorization Act (NDAA), I will be forced to unequivocally VETO the Bill when sent to the very beautiful Resolute desk. Take back America NOW. Thank you!— Donald J. Trump (@realDonaldTrump) December 2, 2020 Trump has been waging war against social media companies for months, claiming they are biased against conservative voices.Since his reelection bid failed, Trump has continued to flood his social media channels with unsubstantiated claims of voter fraud. On Twitter, many of his tweets have been tagged with the advisory, “This claim about election fraud is disputed.”Tuesday’s veto threat isn’t the only thing standing in the way of the defense bill being signed into law. The Associated Press found the legislation is being held up in Congress due to an argument over military bases that are named for Confederate officers. The topic gained national attention during the summer as people across the country advocated for racial equality and justice. 1607

WASHINGTON (AP) — The official serving as President Donald Trump’s eyes and ears at the Justice Department has been banned from the building after trying to pressure staffers to give up sensitive information about election fraud and other matters she could relay to the White House, three people familiar with the matter tell The Associated Press.Heidi Stirrup, an ally of top Trump adviser Stephen Miller, was quietly installed at the Justice Department as a White House liaison a few months ago. She was told within the last two weeks to vacate the building after top Justice officials learned of her efforts to collect insider information about ongoing cases and the department’s work on election fraud, the people said.Stirrup is accused of approaching staffers in the department demanding they give her information about investigations, including election fraud matters, the people said. They spoke on condition of anonymity because they were not authorized to publicly discuss the matter.The effort came as Trump continues to level baseless claims that he won the election and alleges without evidence that massive voting fraud was responsible for his defeat to President-elect Joe Biden.Stirrup had also extended job offers to political allies for positions at some of the highest levels of the Justice Department without consulting any senior department officials or the White House counsel’s office and also attempted to interfere in the hiring process for career staffers, a violation of the government’s human resources policies, one of the people said.The Justice Department declined to comment. Attempts to reach Stirrup for comment were not immediately successful. 1686
