The new science of “emergent misalignment” explores how PG-13 training data — insecure code, superstitious numbers or even ...

The effects of insufficient water are felt by every cell in the body, but it’s the brain that manifests our experience of ...

Strong new evidence suggests that primordial material from the planet’s center is somehow making its way out. Continent-size ...

A small but enthusiastic group of neuroscientists is exhuming overlooked experiments and performing new ones to explore whether cells record past experiences — fundamentally challenging what memory is ...

A canonical problem in computer science is to find the shortest route to every point in a network. A new approach beats the classic algorithm taught in textbooks.

Results from neural networks support the idea that brains are “prediction machines” — and that they work that way to conserve energy.

Hybrids, once treated as biological misfits, play a vital role in the evolution of many animal species. Now conservationists are trying to reconcile that truth with policies.

The puzzling behavior of black hole interiors has led researchers to propose a new physical law: the second law of quantum complexity.

Number theorist Andrew Granville on what mathematics really is — and why objectivity is never quite within reach.

John Clauser, Anton Zeilinger and Alain Aspect have won the 2022 Nobel Prize in Physics for groundbreaking experiments with entangled particles.

By treating Earth as a topological insulator — a state of quantum matter — physicists found a powerful explanation for the movements of the planet’s air and seas.
