The apparent paradox of the chicken and the egg smells like “turtles all the way down.” This puzzle shows how biology and physics can overcome infinite regress.

James P. Allison believed that unleashing the immune system was a way to beat cancer when almost no one else did. A Nobel Prize and a growing list of cancer survivors vindicate him.

The glial cells of the nervous system have been eclipsed in importance by neurons for decades. But glia are turning out to be central to many neurological functions, including pain perception.

Collaborations in progress between ethicists and biologists seek to head off challenges raised by lab-grown “organoids” as they become increasingly similar to human brain tissue.

The noted mathematician and author Steven Strogatz explains why he wanted to share intimate conversations with leading researchers from diverse fields in his new podcast.

The dendritic arms of some human neurons can perform logic operations that once seemed to require whole neural networks.

In evolution, context is everything: Bacteria with neighbors evolve to rebuff viruses in a different way.

To scientists’ surprise, blended mixtures of cytoplasm can reorganize themselves into cell-like compartments with working structural components.
