The first animal genus defined purely by genetic characters represents a new era for the sorting and naming of animals.

How much stock should we put in mathematical models of evolution that have not been validated by rigorous empirical data?

Gene-sequence data is changing the way that botanists think about their classification schemes. A recent name-change for a common houseplant resulted from the discovery that it belonged in an overlooked genus.

Once again, body cells reveal unexpected plasticity: In a newly discovered type of wound healing, which some researchers call “paligenosis,” adult cells revert to a more fetal state.

Quanta’s In Theory video series returns with an exploration of a mysterious mathematical pattern found throughout nature.

The identification of SNIPPs, a set of proteins found primarily at the brain’s synapses, brings science closer to understanding why we need to sleep.

A unique neurological “functional fingerprint” allows scientists to explore the influence of genetics, environment and aging on brain connectivity.

Evolutionary stories like the grandmother hypothesis are easy to construct from mathematical models, but how well do they reflect reality?

Evolution may have coopted an ancient metabolic mechanism to set social insects on the path toward one of the most puzzling behaviors found in nature.
