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.

To Learn More Quickly, Brain Cells Break Their DNA

August 30, 2021

New work shows that neurons and other brain cells use DNA double-strand breaks, often associated with cancer, neurodegeneration and aging, to quickly express genes related to learning and memory.

The Brain Doesn’t Think the Way You Think It Does

August 24, 2021

Familiar categories of mental functions such as perception, memory and attention reflect our experience of ourselves, but they are misleading about how the brain works. More revealing approaches are emerging.

Animals Count and Use Zero. How Far Does Their Number Sense Go?

August 9, 2021

Crows recently demonstrated an understanding of the concept of zero. It’s only the latest evidence of animals’ talents for numerical abstraction — which may still differ from our own grasp of numbers.

Plasmid, Virus or Other? DNA ‘Borgs’ Blur Boundaries.
