There's nothing like a shot of espresso when you need to get some studying done -- and now, it seems like bees learn better with a jolt of their favorite caffeine-laced nectar, too. In a paper published July 28 in the journal Current Biology, researchers have shown that feeding bumble bees caffeine helps them better remember the smell of a specific flower with nectar inside. While previous studies have shown that bees like caffeine and will more frequently visit caffeinated flowers to get it, this is the first study to show that consuming caffeine in their nest actually helps bees find certain flowers outside of the nest.
