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

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.

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

A recent test has confirmed the predictions of quantum trajectory theory, which describes what happens during the long-mysterious “collapse” of a quantum system.

Lee Smolin has a radical idea for how to understand an object with no exterior: Imagine it built bit-by-bit from relationships between events.

Lurking behind Einstein’s theory of gravity and our modern understanding of particle physics is the deceptively simple idea of symmetry. But physicists are beginning to question whether focusing on symmetry is still as productive as it once was.

What do moiré patterns seen in optics, art, photography and color printing have to do with superconducting layers of graphene?

In just three pages, a Russian mathematician has presented a better way to color certain types of networks than many experts thought possible.

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

A recent challenge to Stephen Hawking’s biggest idea — about how the universe might have come from nothing — has cosmologists choosing sides.
