An analysis of lunar craters has found that we’ve been living in a relatively violent period in cosmic history.

Astronomers couldn’t find enough satellite galaxies orbiting the Milky Way. Now they have the opposite problem, suggesting that our understanding of how galaxies get built is incomplete.

Dark matter may occasionally interact with minerals in the earth, leaving telltale tracks that physicists hope to decipher.

The same codes needed to thwart errors in quantum computers may also give the fabric of space-time its intrinsic robustness.

In a Paris lab, researchers have shown for the first time that quantum methods of transmitting information are superior to classical ones.

Equations, like numbers, cannot always be split into simpler elements. Researchers have now proved that such “prime” equations become ubiquitous as equations grow larger.

A thought experiment has shaken up the world of quantum foundations, forcing physicists to clarify how various quantum interpretations (such as many-worlds and the Copenhagen interpretation) abandon seemingly sensible assumptions about reality.

Simple physical principles can be used to describe how rivers grow everywhere from Florida to Mars.

With proteins that reversibly self-assemble into droplets, cells may control their metabolism — and harden themselves against harsh conditions.

Quasars powered by supermassive black holes have been unexpectedly vanishing. Scientists have started to figure out why.
