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

Perineuronal nets, rigid structures that hold certain neurons in place, affect a surprising amount of brain activity, including some associated with chronic pain.

Everybody gets older, but not everyone ages in the same way. In this episode, Steven Strogatz speaks with Judith Campisi and Dena Dubal, two biomedical researchers who study the aging process.

New research finds that chaos plays a bigger role in population dynamics than decades of ecological data seemed to suggest.

Structural studies of the robust material called sporopollenin reveal how it made plants hardy enough to reproduce on dry land.

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.

A new origins-based system for classifying minerals reveals the huge geochemical imprint that life has left on Earth. It could help us identify other worlds with life too.

Protein buildups like those seen around neurons in Alzheimer’s, Parkinson’s and other brain diseases occur in all aging cells, a new study suggests. Learning their significance may reveal new strategies for treating age-related diseases.
