The nervous systems of foraging and predatory animals may prompt them to move along a special kind of random path called a Lévy walk to find food efficiently when no clues are available.

Recent findings add weight to the evidence that the intransitive competitions between species enrich the diversity of nature.

Mathematicians and neuroscientists have created the first anatomically accurate model that explains how vision is possible.

During development, cells seem to decode their fate through optimal information processing, which could hint at a more general principle of life.

A primordial developmental toolkit shared by all vertebrates, and described by a theory of the mathematician Alan Turing, sets the growth pattern for all types of skin structures.

Some researchers are using a complexity framework thought to be purely theoretical to understand evolutionary dynamics in biological and computational systems.

New results emerging from graph theory prove that the way a population is organized can guarantee the eventual triumph of natural selection — or permanently thwart it.

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

The long, variable times that some diseases incubate after infection defies simple explanation. An idealized model of tumor growth offers a statistical solution.
