Abnormal waves of electrical activity can cause a heart’s muscle cells to beat out of sync. In this episode, Flavio Fenton, an expert in cardiac dynamics, talks with Steve Strogatz about ways to treat heart arrhythmias without resorting to painful defibrillators.

Nikta Fakhri is adapting and extending concepts from physics to describe how tiny biological components give rise to living organisms.

Robots can surpass the limitations on how high and far animals can jump, but their success only underscores nature’s ingenuity in making the most of what’s available.

By studying how electric organs arose in different lineages of fish, scientists gain new insights into a long-standing question of evolutionary biology.

Partnerships between engineers and biologists have begun to reveal how birds evolved their superb maneuverability.

Patterns that guide the development of feathers and other features can be set by mechanical forces in the embryo, not just by gradients of chemicals.

Physicists have solved a key problem of robotic locomotion by revising the usual rules of interaction between simple component parts.

Researchers say we’re on the cusp of “GoPro physics,” where a camera can point at an event and an algorithm can identify the underlying physics equation.

The optical properties of mitochondrial bundles in the retina may improve how efficiently the eye captures light.
