Scientists Map 5,000 New Ocean Viruses

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.

Animal Copies Reveal Roots of Individuality

Genetically identical animals raised under similar conditions can make very different choices. These distinctions are helping researchers map the biological basis of individuality.

A Surprise for Evolution in Giant Tree of Life

The largest evolutionary tree ever compiled leads researchers to conclude that chance mutation — not natural selection — drives the development of new species.

Genetic Geometry Takes Shape

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.

Machine Intelligence Cracks Genetic Controls

Scientists have begun to decipher the most difficult-to-read parts of the genome — the parts that don’t code for proteins. The new work reveals how errors in these genetic instructions can lead to disease.

Evolution’s Random Paths Lead to One Place

A massive statistical study suggests that even though genetic changes happen at random, the final evolutionary outcome — fitness — is predictable.

I Contain Multitudes

Our bodies are a genetic patchwork, possessing variation from cell to cell. Is that a good thing?
