Scientists have struggled to formulate a universal definition of life. Is it possible they don’t need one?

Recent discoveries have led some researchers to argue that the modern evolutionary synthesis needs to be amended.

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.

Interest in a powerful DNA editing tool called CRISPR has revealed that bacteria are far more sophisticated than anyone imagined.

Newly discovered patterns in evolution may help scientists make accurate short-term predictions.

Scientists are exploring how organisms can evolve elaborate structures without Darwinian selection.
