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.
The comb jelly, a primitive marine creature, is forcing scientists to rethink how animals got their start.
An infection sweeping through Australia’s struggling koala population provides an unprecedented opportunity to explore how retroviruses insert themselves into the genome.
Inside the cell’s nucleus, the double helix folds up in myriad loops and twists. The quest to unravel this structure is revealing the subtle genetic orchestration of all life on Earth.
A new solution to the prisoner’s dilemma, a classic game theory scenario, has created new puzzles in evolutionary biology.
Interest in a powerful DNA editing tool called CRISPR has revealed that bacteria are far more sophisticated than anyone imagined.
