Phys.org / Chimpanzees in Uganda use flying insects to tend their wounds, study reveals

Animals respond to injury in many ways. So far, evidence for animals tending wounds with biologically active materials is rare. Yet, a recent study of an orangutan treating a wound with a medicinal plant provides a promising ...

Phys.org / New earthquake model goes against the grain

When a slab slides beneath an overriding plate in a subduction zone, the slab takes on a property called anisotropy, meaning its strength is not the same in all directions. Anisotropy is what causes a wooden board to break ...
