Humans aren't the only animals who benefit from a shot of caffeine before heading off to work. A new study published in Current Biology shows that bumble bees also benefit – working more efficiently (hiệu quả) and with improved memory (tăng cường trí lực) – when buzzing on a dose of the good stuff.

Researchers led by Sarah Arnold, a senior lecturer of insect (côn trùng) behavior and ecology (sinh thái học) at the University of Greenwich, have provided the first evidence that caffeinated bees are better equipped to find target crops, regardless of whether those targets contain caffeine. In other words, a little caffeine buzz helped the bees do their everyday jobs more efficiently.

Scientists have already shown that these bees will preferentially return to flowers that contain caffeinated nectar (rượu tiên, mật hoa), which can improve their memories and boost their efficiency as foragers (người cắt cỏ, người lục lọi, người cướp phá/đánh phá) and pollinators (thụ phấn).
