Biophysics

By measuring mechanical forces inside an embryo for the first time, researchers have shown how a physical “jamming” mechanism assists development.

Psychedelic drugs can trigger characteristic hallucinations, which have long been thought to hold clues about the brain’s circuitry. After nearly a century of study, a possible explanation is crystallizing.

Researchers explore a loophole that extracts useful energy from a fluid’s seemingly random motion. The secret? Sugar and asymmetry.

In a renewed attempt at a grand unified theory of brain function, physicists now argue that brains optimize performance by staying near — though not exactly at — the critical point between two phases.

Elastic springs help tiny animals stay fast and strong. New work is finding what size critters must be to benefit from the springs.

Researchers are building a case that long before the nervous system works, the brain sends crucial bioelectric signals to guide the growth of embryonic tissues.

With electrical signals, simple cells organize themselves into complex societies and negotiate with other colonies.

Take chemistry, add energy, get life. The first tests of Jeremy England’s provocative origin-of-life hypothesis are in, and they appear to show how order can arise from nothing.

The new experiments suggest that simple models can explain the behavior of thousands of interacting organisms.
