A group of mathematicians has shown that at critical moments, a symmetry called rotational invariance is a universal property across many physical systems.

A temporal pattern of activity observed in human brains may explain how we can learn so quickly.

Mitochondria appear to communicate and cooperate with one another, both within and between cells. Biologists are only just beginning to understand how and why.

Other diseases with long-term symptoms can help us understand how COVID can affect us long after the virus itself is gone.
