This undated image made available by Geraldine Wright shows a honeybee visiting a citrus flower. A new study says honeybees get a shot of caffeine from certain flowers, and it perks up their memory. That spurs them to return to the same type of plant, boosting its prospects for pollination and the future of the plant species. Some citrus plants such as orange and grapefruit blossoms have a small amount of caffeine. The work, by Geraldine Wright of Newcastle University in England and co-authors, was reported Thursday, March 7, 2013 in the journal Science. (AP Photo/Geraldine Wright)
