Bees love caffeine buzz, study shows

Honeybees, like tired office employees, like their caffeine, suggests a new study finding that bees are more likely to remember plants containing the java ingredient. Caffeine occurs naturally in the nectar of coffee and citrus flowers. Bees that fed on caffeinated nectar were three times more likely to remember a flower's scent than bees fed sugar alone. The findings, detailed Thursday in the journal Science, show how plants can manipulate animals' memories to improve their odds of pollination.
Plants produce caffeine as a defense mechanism — a bitter-tasting brew to fend off insects. Fortunately for the bees, the caffeine levels are below the threshold that they can taste, but high enough to affect their memory, according to the Science article.

The mention of bees is a reminder that summer is just around the corner. That means Discovery Student Adventures is preparing to jet away to amazing destinations around the world.
