Researchers have found that such feral colonies may have higher tolerance to… view more  Credit: Katy Evans, Penn State Understanding the genetic and environmental factors that enable some feral honey bee colonies to tolerate pathogens and survive […]

Shedding light on the secret reproductive lives of honey bees — ScienceDaily

Honey bee health has been on the decline for two decades, with U.S. and Canadian beekeepers now losing about 25 to 40% of their colonies annually. And queen bees are failing faster than they have in the past in their ability to reproduce. The reason has been a mystery, but researchers at North Carolina State […]

Brain gene expression patterns predict behavior of individual honey bees

Researchers used barcodes to track individual honey bees in a study that looked for parallels between the bees’ foraging and egg-laying behavior and patterns of gene expression in their brains.

Pesticide deadly to bees now easily detected in honey — ScienceDaily

A common insecticide that is a major hazard for honeybees is now effectively detected in honey thanks to a simple new method. Researchers at the University of Waterloo developed an environmentally friendly, fully automated technique that extracts pyrethroids from the honey. Pyrethroids are one of two main groups of pesticides that contribute to colony collapse […]

When honey flows faster than water — ScienceDaily

It’s widely known that thick, viscous liquids — like honey — flow more slowly than low-viscosity liquids, like water. Researchers were surprised to find this behaviour flipped on its head when the liquids flow through chemically coated capillaries. In fact, through these specially coated tubes, liquids a thousand times more viscous flow ten times faster. […]
