Astronomers thought they had solved the mystery of gamma-ray bursts. A few recent events suggest otherwise.

Erin Calipari works to understand how drugs like opioids and cocaine alter learning circuits and neurochemistry in one of the country's epicenters of substance use disorder and addiction.

A team of four prominent mathematicians, including two Fields medalists, proved a conjecture described as a “holy grail of additive combinatorics.”

A century ago, the Stern-Gerlach experiment established the truth of quantum mechanics. Now it’s being used to probe the clash of quantum theory and gravity.

Researchers prove that navigating certain systems of vectors is among the most complex computational problems.

Mathematicians prove a theorem that illuminates the geometry of universes with tiny amounts of mass.

Modern scientists aren’t content with predicting how life evolves. They want to shape it.

Paradoxically, natural selection can sometimes seem to block organisms from evolving useful adaptations. But a new study of “fitness landscapes” and antibiotic resistance in bacteria shows that life still finds a way.

For 50 years, physicists have understood current as a flow of charged particles. But a new experiment has found that in at least one strange material, this understanding falls apart.
