How long does a whale feed? New data gives insight into blue and fin whale behavior

Researchers used electronic tags to monitor blue and fin whales' feeding behaviors over multiple weeks, providing unprecedented detail about their daily feeding patterns. The study found that both species have similar feeding bout characteristics, with slight differences observed between males and females.

Female gorillas detect and avoid sick groups

A research team studied 593 gorillas over a decade, finding females migrate to healthier groups to avoid transmission of yaws, a contagious skin disease. The scientists discovered that females can detect one symptom of the disease: disfigurement.

Solving the longstanding mystery of how friction leads to static electricity

Researchers developed a new model that shows rubbing two objects together produces static electricity by bending tiny deformations on the surface of materials. This phenomenon, called flexoelectricity, arises from the separation of charge in an insulator due to deformations such as bending.

Long before other fish, ancient sharks found an alternative way to feed

A new study describes a 2-foot long shark with jaws capable of suction feeding, 50 million years older than the earliest evidence in bony fishes. The fossil, analyzed using CT imaging and modeling software, shows that ancient sharks responded quickly to ecological opportunities after major extinctions.

Sulphur emissions from marine algae dropped during glacial periods

Research found that sulphur production by tiny marine algae decreased during glacial periods, challenging conventional wisdom. This decrease in sulphur emissions may be linked to changes in climate rather than just the amount of dust in the air, suggesting a closer relationship between phytoplankton and climate.
