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.
