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

After an interstellar asteroid shot past the sun, scientists realized that there’s probably a lot of itinerant rocks out there.

Although Einstein’s theory of space-time seems more complicated than Newtonian physics, it greatly simplified the mathematical description of the universe.

Consciousness is a famously hard problem, so Hod Lipson is starting from the basics: with self-aware robots that can help us understand how we think.

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.

Randomness would seem to make a mathematical statement harder to prove. In fact, it often does the opposite.

The discovery that apparently dead cells can sometimes resurrect themselves has researchers exploring how far they can push the point of no return.

A recent test has confirmed the predictions of quantum trajectory theory.

Mathematicians have proved that a random process applied to a random surface will yield consistent patterns.
