Today's round-up of science stories. Links are normally to press releases on EurekAlert (at the bottom end I may also add a couple of newspaper stories). I include quotes from the summary (using quotation marks) in cases where the title alone doesn't reveal what the story is about.
(Categories are still evolving. Don't really want to put stuff in boxes, but have to have some kind of structure here.)

Bee mite arrival in Hawaii causes pathogen changes in honeybee predators
"A team led by entomologists at the University of California, Riverside, performed a study on the Big Island and found viruses associated with the varroa mite, a parasite of honeybees, have spilled over into the western yellowjacket, a honeybee predator and honey raider. The result is a hidden, yet remarkable, change in the genetic diversity of viruses associated with the larger pathogen community of the mite and wasp, with repercussions yet to be understood."
