Ethiopian Airlines crash: Boeing reduces 737 production

Ethiopian Airlines crash: Boeing reduces 737 production

Business
Media playback is unsupported on your device Boeing is temporarily cutting production of its best-selling 737 airliner in the continuing fall-out from crashes in Ethiopia and Indonesia. Production will drop from 52 planes a month to 42 from mid-April, Boeing has said in a statement. The decision is a response to a halt in deliveries of the 737 Max - the model involved in the two accidents. The plane is currently grounded as preliminary findings suggest its anti-stall system was at fault. An Ethiopian Airlines 737 Max crashed only minutes after take-off from Addis Ababa in March, killing all 157 people on board. The same type flown by the Indonesian airline Lion Air crashed into the sea only five months earlier, shortly after taking off from J...
Commercial agriculture reduces butterfly diversity by two-thirds

Commercial agriculture reduces butterfly diversity by two-thirds

Science
March 20 (UPI) -- Pollinators are on the decline. Bee numbers are steadily decreasing, and as new research out of Germany confirms, butterfly numbers are down, too. Scientists found the number of butterfly species in meadows next to commercial agriculture are two-thirds less than the number of butterfly species found in nature preserves. Researchers surveyed butterfly species in 21 meadow sites outside of Munich. Four of the sites were situated in nature preserves, while the remaining 17 were adjacent to areas featuring high-intensity agriculture. In total, scientists counted 864 individual butterflies, comprising 24 different species. Butterfly species considered generalists were found in both nature preserves and farm-adjacent meadows. Specialist species were less likely to be found ne...
Exposure to pesticides makes bees less social, reduces colony size

Exposure to pesticides makes bees less social, reduces colony size

Science
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

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...
