Volunteers check honey bee hives for queen activity and perform routine maintenance as part of a collaboration between the Cincinnati Zoo and TwoHoneys Bee Co. at EcOhio Farm in Mason, Ohio, in 2015. A new study published Thursday in the journal Science found something in the world's honey that is not quite expected or sweet: the controversial pesticides called neonicotinoids. Scientists say it is not near levels that would come close to harming humans, but it is a big worry for bees, which already are in trouble. | AP
