Evolutionary history of honeybees revealed by genomics
In a study published in Nature Genetics, researchers from Uppsala University present the first global analysis of genome variation in honeybees. The findings show a surprisingly high level of genetic divers ...
Bees get a buzz from caffeine
Scientists have today shown that caffeine improves a honeybee's memory and could help the plant recruit more bees to spread its pollen.
Honeybee secretion may find use as local anesthetic
Bigger not necessarily better, when it comes to brains
(PhysOrg.com) -- Tiny insects could be as intelligent as much bigger animals, despite only having a brain the size of a pinhead, say scientists at Queen Mary, University of London.
What is the meaning of 'one'? Evolutionary biologists argue for new meaning of 'organismality'
Rice University evolutionary biologists David Queller and Joan Strassmann argue in a new paper that high cooperation and low conflict between components, from the genetic level on up, give a living thing its "organismality," ...
Honey-bee aggression study suggests nurture alters nature
A new study reveals that changes in gene expression in the brain of the honey bee in response to an immediate threat have much in common with more long-term and even evolutionary differences in honey-bee aggression. ...
Honeybees not fooled by cheating flowers
(PhysOrg.com) -- Flowers that want to cheat pollinators by not paying them for their services shouldn’t try to lure them in using floral scents, scientists at Newcastle University have shown.
How does a honeybee queen avoid inbreeding in her colony?
Recombination, or crossing-over, occurs when sperm and egg cells are formed and segments of each chromosome pair are interchanged. This process plays an crucial role in the maintanance of genetic variation. ...
Discovery aims to fight destructive bee disease
University of Guelph researchers hope their new discovery will help combat a disease killing honeybee populations around the world.
Spider venom may save the bees
Venom from one of the world's most poisonous spiders may help save the world's honeybees, providing a biopesticide that kills pests but spares the precious pollinators, a study said Wednesday.
Honeybees show tipping points
Parasites, lack of food, cold snaps, pesticides, and poor management all can stress honeybee colonies, making it difficult to pin their collapse on a single source. However, in controlled field tests, honeybee ...
US survey finds 23% of bee colonies died this winter
Nearly one out of four American honeybee colonies died this winter—a loss that's not quite as bad as recent years, says a new U.S. Department of Agriculture survey of beekeepers.
Managed honeybees linked to new diseases in wild bees
Diseases that are common in managed honeybee colonies are now widespread in the UK's wild bumblebees, according to research published in Nature. The study suggests that some diseases are being driven into w ...
Common crop pesticides kill honeybee larvae in the hive
Four pesticides commonly used on crops to kill insects and fungi also kill honeybee larvae within their hives, according to Penn State and University of Florida researchers. The team also found that N-methyl-2-pyrrolidone ...
