Slight changes in the number, shape, efficiency and interconnectedness of organelles in the cells of flight muscles provide extra energy for birds’ continent-spanning feats.

From living matter to molecules to elementary particles, the world is made of “chiral” objects that differ from their reflected forms.

How do memories last a lifetime when the molecules that form them turn over within days, weeks or months? An interaction between two proteins points to a molecular basis for memory.

The brain’s astounding cellular diversity and networked complexity could show how to make AI better.

Exploring the distant universe, the insides of cells, the abstractions of math, the complexity of information itself and much more, The Quanta Podcast will be a tour of the frontier between the known and the unknown.

Micro decisions can have macro consequences. A soft matter physicist reveals how interactions within simple cellular collectives can lead to emergent physical traits.

Every soft caress of wind, searing burn and seismic rumble is detected by our skin’s tangle of touch sensors. David Ginty has spent his career cataloging the neurons beneath everyday sensations.

Complex neural pathways likely arose independently in birds and mammals, suggesting that vertebrates evolved intelligence multiple times.

A popular hypothesis for how the brain clears molecular waste, which may help explain why sleep feels refreshing, is a subject of debate.
