Exposure to pesticides makes bees less social, reduces colony size

Nov. 9 (UPI) -- Exposure to pesticides can reduce the size of bee colonies and cause the insect to become less social. Researchers published those findings in the journal Science. A team of researchers, led by Harvard University's James Crall, used a robotic bench that allowed them to study the behavior patterns of as many as a dozen bee colonies at once. They observed that after pesticide exposure, bees spent less time nursing larvae and less time socializing with other bees. They also saw that exposure prevented the bees from building protective wax caps around their colony or warming the nest. "These pesticides first came into use around the mid-1990s, and are now the most commonly-used class of insecticide around the globe," Crall said in a press release. "Typically, they work throug...

Research: Blood thinner reduces risk after heart damage in surgery

Health
March 12 (UPI) -- A blood-thinning drug significantly reduces the risk of complications from a heart injury after major non-cardiac surgery, report researchers in Canada.Researchers found dabigatran was effective in the first randomized controlled study to evaluate ways to reduce such heart injuries, according to study results presented last week at the American College of Cardiology's annual conference in Orlando last week. Dabigatran is sold under the brand name Pradaxa, which is made by Boehringer Ingelheim, a drugmaker that helped fund the study.The study was conducted by the Population Health Research Institute of McMaster University and Hamilton Health Sciences in Ontario, Canada."We now have an option for improving outcomes for a large population of people who have a heart injury af...
