Origin-of-life researchers have usually studied the potential of pure starting materials, but messy mixtures of chemicals may kick-start life more effectively.

Modern humans and more ancient hominins interbred many times throughout Eurasia and Africa, and the genetic flow went both ways.

Modeling suggests that many embryonic cells commit to a developmental fate when they become too small to divide unevenly anymore.

Researchers found that elongating certain brain signals in rats improved their memory. The work revealed a new property to look out for in the hunt for “biomarkers” of learning.

Theories about how animals became multicellular are shifting as researchers find greater complexity in our single-celled ancestors.

By studying a swarm of flying midges as though it were a fluid, physicists have learned how collective behaviors might stabilize a group against environmental disruptions.

To researchers’ surprise, deep learning vision algorithms often fail at classifying images because they mostly take cues from textures, not shapes.

Contrary to popular belief, bacteria have organelles too. Scientists are now studying them for insights into how complex cells evolved.

Immunologists confirm an old hunch: T-cells identify what belongs in the body by timing how long they can bind to it.
