‘Traffic Jams’ of Cells Help to Sculpt Embryos

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

A Math Theory for Why People Hallucinate

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.

Swarming Bacteria Create an ‘Impossible’ Superfluid

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

Brains May Teeter Near Their Tipping Point

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.

Too Small for Big Muscles, Tiny Animals Use Springs

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

Brainless Embryos Suggest Bioelectricity Guides Growth

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.

Bacteria Use Brainlike Bursts of Electricity to Communicate

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

First Support for a Physics Theory of Life

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.

Swirling Bacteria Linked to the Physics of Phase Transitions

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