Bumblebees Can Now Understand Morse Code

At Queen Mary University of London, behavioral scientist Alex Davidson and his team designed a test using flashes of light—short and long pulses that signaled different outcomes. A long flash meant yummy sugar water. A short one meant a bitter shot of quinine, which they hate. After a series of trials, the bees began choosing the light associated with sweetness every time, even when the sugar was removed entirely.
