Circulating RNAs carry messages for plants and invertebrates. Do they do the same for us?

Neuroscientists have identified a network of highly linked brain regions that could prove essential in integrating information and facilitating higher-order cognitive tasks.

New technologies have launched the life sciences into the age of big data. Biologists must now make sense of their windfall.

As science dives headlong into an ocean of data, the demands of large-scale interdisciplinary collaborations are growing increasingly acute.

An interview with the developmental biologist Cassandra Extavour on the origins of multicellular organisms and the evolution of cooperation.

A computational study reveals surprising flexibility hidden within metabolic networks, providing new evidence for an evolutionary concept called exaptation.

Machine learning techniques are helping scientists pinpoint the mutations that allow bird and pig viruses to infect humans.

In the complex architecture that ferries fluids in plants and brains, scientists are finding a model of resilience.

Population expansion may be a major driver in the evolution of cooperation, with implications for new antibiotics, cancer treatments and perhaps even human behavior.
