Scientists hope that new genetic letters, created in the lab, will endow DNA with new powers.
The biologist Deborah Gordon has uncovered how ant colonies search efficiently without central organization, an insight that might improve computer networks.
By swapping ancient genes into modern E. coli, scientists hope to tease out the rules of evolution.
The soil teems with billions of hidden microbes. Researchers have begun to catalog how these organisms are changing the world.
Modern birds emerged in a snap of evolutionary time through a series of simple genetic changes.
In the few decades since viruses were first found in the oceans, scientists have only been able to identify a handful of species. A new survey has uncovered nearly all the rest.
Genetically identical animals raised under similar conditions can make very different choices. These distinctions are helping researchers map the biological basis of individuality.
The largest evolutionary tree ever compiled leads researchers to conclude that chance mutation — not natural selection — drives the development of new species.
Life’s first epoch saw incredible advances — cells, metabolism and DNA, to name a few. Researchers are resurrecting ancient proteins to illuminate the biological dark ages.
