Phys.org / Well-worn wins: Wild capuchin monkeys prefer stones with a proven track record of cracking nuts

A new study provides experimental evidence that wild capuchin monkeys use more than just physical cues when selecting stone tools; they also rely on visible signs that a stone has previously been used for this purpose.

Phys.org / Electric field reverses phonon chirality and spin direction in ferroelectric crystal

Chiral phonons are groups of atoms that move in a circular direction when excited by an energy source, such as heat. As the phonons move through a material, they propagate that circular motion, or angular momentum, through ...
