Phys.org / Physicists observe polaron formation for the first time

When an electron travels through a polar crystalline solid, its negative charge attracts the positively charged atomic cores, causing the surrounding crystal lattice to deform. The electron and lattice distortion then move ...

Phys.org / From cells to companies: Study shows how diversity scales within complex systems

A mystery novel, a history book, and a fantasy epic may have little in common in plot or style. But count the words inside them and a strange regularity appears: many new words show up early, then fewer and fewer as the author ...

Phys.org / Not all humans are 'super-scary' to wildlife, animal behavior study suggests

Humans have climbed to the top of the food chain by skillfully hunting, trapping, and fishing for other animals at scales that far exceed other predators, altering how the animals behave and earning the tag of a "super-predator." ...
