While scientists have documented cases of tiny flies infesting honeybees, causing the bees to lurch and stagger around like zombies before they die, researchers don’t know the scope of the problem. Now they are getting help in tracking the honeybee-killing parasite from ZomBee Watch, created in 2012 by John Hafernik, a biology professor at San Francisco State University.

“We’re not making a case that this is the doomsday bug for bees,” said John Hafernik, a biology professor at San Francisco State University. “But it is certainly an interesting situation where we have a parasite that seems to affect the behavior of bees and has them essentially abandoning their hive.”

FOR RELEASE FRIDAY, OCT. 9, 2015, AT 3:00 A.M. EDT - In this photo taken Sept. 9, 2015, Kevin Esvelt poses for a photo at Harvard University's Wyss Institute in Boston. The hottest tool in biology has scientists using words like revolutionary as they describe the long-term potential: wiping out certain mosquitoes that carry malaria, treating genetic diseases like sickle-cell, preventing babies from inheriting a life-threatening disorder. Esvelt's projects include genetically manipulating a mosquito species to fight malaria.  (AP Photo/Rodrique Ngowi)

“We need to try to get the balance right,” said Jennifer Doudna, a biochemist at the University of California, Berkeley. She helped develop new gene-editing technology and hears from desperate families, but urges caution in how it’s eventually used in people.

Stephen Vouch of Boise, talks to a reporter on Wednesday, Oct. 7, 2015 at the Idaho Department of Fish and Game in Boise, Idaho and describes being bitten in the back of the head by a black bear while he slept at a hunting camp in central Idaho on Oct. 2. The attack left Vouch, 29, with cuts to the back of his head but he didn't need stitches. A hunting companion shot and wounded the bear that Vouch then shot and killed. State officials estimated the black bear was 3 to 7 years old and weighed from 200 to 275 pounds. (AP Photo/Keith Ridler)

“He got a hold of my head, and that’s what woke me up,” the Boise resident said Wednesday, who was in the rugged area hunting bighorn sheep with friends. “That’s when I kind of freaked out. That’s when I could hear the bear breathing on me.”
