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

A statistical analysis of chemical tags on DNA may help unify disparate theories of aging.

The biochemist Nick Lane thinks life first evolved in hydrothermal vents where precursors of metabolism appeared before genetic information. His ideas could lead us to think differently about aging and cancer.

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.
