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, Mo. - A Missouri middle schooler died this weekend due to complications from COVID-19.The School District of Washington, Missouri, said eighth-grader Peyton Baumgarth was hospitalized due to the virus's symptoms and passed away over the weekend.Superintendent Lori VanLeer said in a letter to parents, the district extends its "heartfelt sympathy" to his family and asked the public to respect their privacy.She wrote that the family asks everyone to follow COVID-19 safety precautions such as washing hands and wearing masks. "COVID-19 is real, and they want to remind students and parents to take these precautions in and outside of school," VanLeer wrote.Additional counselors will be available at the school Wednesday, according to the letter.Peyton's last day at school was Oct. 22. VanLeer said the school was informed he was in quarantine on Oct. 26.According to local media stations KMOV and KSDK, Baumgarth was the state's youngest victim of the deadly virus. However, the Missouri Department of Health and Senior Services coronavirus database, which tracks the state's COVID-19 cases, deaths, and hospitalizations, by age, race, and ethnicity, did not have Baumgarth's death posted on its latest update, which was last updated Monday morning.Washington, Missouri, is located about an hour west of St. Louis.Hailey Godburn first reported this story at KSHB in Kansas City, Missouri. 1411

WASHINGTON, D.C. – At least 59,494 new coronavirus cases were reported in the United States on Wednesday, which is the highest daily count since August 14, according to a tally by Johns Hopkins University.The data shows there was also an increase in the number of deaths, with at least 985 reported Wednesday, up from 802 the day before.The nation’s total coronavirus cases stand at about 7,917,300 and more than 216,900 deaths from COVID-19, John Hopkins says. Those cases include people in all 50 states, Washington D.C. and U.S. territories.As has been the case throughout the pandemic, the U.S. leads the world in the number of reported COVID-19 cases and deaths, followed by India, Brazil and Russia.The current rise in cases in several areas of the U.S. has many infectious disease experts worried about a large spike in the fall and winter months, a time when the country is using health care resources to battle the flu. To help combat the risk of a "twindemic," doctors are encouraging all Americans to get a flu vaccination.Dr. Anthony Fauci, one of the country’s top coronavirus experts, told ABC News on Thursday that the spike is “concerning” and that “you don’t want to be in that compromised position where your baseline daily infection is high and you are increasing as opposed to going in the other direction.”Click here to learn more from the Centers for Disease Control and Prevention (CDC) about how you can help protect yourself and others from contracting the coronavirus. 1502
