Scientists Assemble Frog Stem Cells Into First ‘Living Machines’

The so-called ‘xenobots’ could replace traditional metal or plastic robots without polluting the planet, but they raise ethical questions

African grey parrots are highly social, and may benefit from establishing reputations for generosity.

Parrots Will Share Currency to Help Their Pals Purchase Food

Animals often share food, but these birds understand that metal rings can be exchanged for treats, and they share the rings with no promise of reward

Cuttlefish are calculating hunters, and need depth perception to efficiently snare their prey.

Scientists Velcroed 3-D Glasses to Cuttlefish to Study Their Depth Perception

The results of the eye-popping study suggest cuttlefish see the world in surprisingly human ways
