Under a microscope, cells in a worm embryo deliberately eliminated one-third of their genome — an uncompromising tactic that may combat harmful genetic parasites.

Genetic elements called Mavericks that have some viral features could be responsible for the large-scale smuggling of DNA between species.

For over a century, biologists have had to contend with a complicated picture of genetics, which they’ve only recently begun to understand.

Changes in the 3D structure of their genome gave skates and rays their distinctive winglike fins and pancake flatness.

On Mount Everest and in the Peruvian Andes, Tracie Seimon uses DNA to study how species and ecosystems respond to climate change, pathogens and other influences.

The first large-scale comparison of mutation rates gives insights into how quickly species can evolve.

The neocortex of our brain is the seat of our intellect. New data suggests that mammals created it with new types of cells that they developed only after their evolutionary split from reptiles.

Depression has often been blamed on low levels of serotonin in the brain. That answer is insufficient, but alternatives are coming into view and changing our understanding of the disease.

The discovery of a hot spot for horizontal gene transfer draws attention to the possible roles of parasites and ecology in such changes.
