Scientists thought that the brain’s hearing centers might just process speech along with other sounds. But new work suggests that speech gets some special treatment very early on.

A new model of learning centers on bursts of neural activity that act as teaching signals — approximating backpropagation, the algorithm behind learning in AI.

When animals move through 3D spaces, the neat system of grid cell activity they use for navigating on flat surfaces gets more disorderly. That has implications for some ideas about memory and other processes.

Benjamin List and David MacMillan received the 2021 Nobel Prize in Chemistry for their development of asymmetrical organocatalysis.

David Julius and Ardem Patapoutian were awarded the 2021 Nobel Prize in Physiology or Medicine for their discoveries of how we detect heat and touch.

How does consciousness arise in mere flesh and blood? To the neuroscientist Anil Seth, our organic bodies are the key to the experience.

Researchers have discovered that environments favoring clumpy growth are all that’s needed to quickly transform single-celled yeast into complex multicellular organisms.

A painstaking study of wing morphology shows both the striking uniformity of individuals in a species and a subtle pattern of linked variations that evolution can exploit.

The molecular signaling systems of complex cells are nothing like simple electronic circuits. The logic governing their operation is riotously complex — but it has advantages.
