Readers poked holes in our paradoxical April Fools’ Day claims about perpetual energy and whether this puzzle solution would ever be published.

Collider physicists report that several measurements of particles called B mesons deviate from predictions. Alone, each oddity looks like a fluke, but their

Neuroscientists could use brain waves to spur immune cells into action against the disease — but the process is almost too fantastic to believe.

By chewing on the problems posed by “extremal” black holes, physicists have exposed a surprising and universal connection between energy and entropy.

Mathematicians try to figure out when problems can be solved using current knowledge — and when they have to chart a new path instead.

To distinguish between fundamentally different objects, mathematicians turn to invariants that encode the objects’ essential features.

Neural networks have been taught to quickly read the surfaces of proteins — molecules critical to many biological processes.

Going without sleep for too long will kill you but scientists haven’t known why. Newly published work suggests that the answer lies in an unexpected part of the

To explain why men are on average taller than women, scientists theorized about competition for mates. But the effects of estrogen on bone growth may be answer enough.

Representation theory was initially dismissed. Today, it’s central to much of mathematics.

After a burst lit up their telescope “like a Christmas tree,” astronomers were able to finally track down the source of these cosmic oddities.

The nervous systems of foraging and predatory animals may prompt them to move along a special kind of random path called a Lévy walk to find food efficiently

We asked four physicists why gravity stands out among the forces of nature. We got four different answers.

Mathematicians typically appreciate either generic or exceptional beauty in their work, but one type is more useful in describing the universe.

Researchers say there are three possible explanations for the anomalous data. One is mundane. Two would revolutionize physics.

Solve a puzzle about mixed dog breeds, sexual reproduction and the COVID-19 pandemic.

The astrophysicist and social media phenom Katie Mack is ready to tell you about the fate of the universe.

Many theories have been offered for why the official COVID-19 toll on the Indian subcontinent has been surprisingly low. The best explanation may be the

One hundred years after it was proposed, the Ising model is used to understand everything from magnets to brains.

While locked down due to COVID-19, Joshua Greene and Andrew Lobb figured out how to prove a version of the “rectangular peg problem.”

Cosmic rays may have given right-handed genetic helixes an evolutionary edge at the beginning of life’s history.
