Recent efforts to map every cell in the human body have researchers floored by unfathomable diversity, with many thousands of subtly different types of cells in the human brain alone.

Astronomers thought they had solved the mystery of gamma-ray bursts. A few recent events suggest otherwise.

For 50 years, physicists have understood current as a flow of charged particles. But a new experiment has found that in at least one strange material, this understanding falls apart.

Sitting alongside the neurons in your enteric nervous system are underappreciated glial cells, which play key roles in digestion and disease that scientists are only just starting to understand.

Scientists have recently discovered scores of free-floating worlds that defy classification. The new observations have forced them to rethink their theories of star and planet formation.

The discovery that the brain has different systems for representing small and large numbers provokes new questions about memory, attention and mathematics.

A new magnum opus posits the existence of a hidden mathematical link akin to the connection between electricity and magnetism.

To better understand how neural networks learn to simulate writing, researchers trained simpler versions on synthetic children’s stories.
