Freeman Dyson — physicist, mathematician, writer and idea factory — died on February 28, but his vitality lives on.

To stay healthy, humans and some other animals rely on a complex community of bacteria in their guts. But research is starting to show that those partnerships might be more the exception than the rule.

The first official evidence of a key imbalance between neutrinos and antineutrinos provides one of the best clues for why the universe contains something rather

For pioneering computer scientist Donald Knuth, good coding is synonymous with beautiful expression.

The legendary mathematician, who died on April 11, was curious, colorful and one of the greatest problem-solvers of his generation.

The inside of a slipping fault line may look something like an avalanche.

And why is the black hole at the center of our own galaxy so dim?

Why did sex evolve? Theories usually focus on the diversity of future generations, but some researchers find compelling explanations in the immediate benefits to individuals.

Physicists have proposed extra cosmic ingredients that could explain the faster-than-expected expansion of space.

Modern mathematics relies on collaboration and travel. COVID-19 is making it increasingly difficult.

As COVID-19 cases continue to increase, our extensive knowledge of other coronaviruses informs our understanding.

The problem of common-sense reasoning has plagued the field of artificial intelligence for over 50 years. Now a new approach, borrowing from two disparate lines

The human mind has long grappled with the elusive nature of time: what it is, how to record it, how it regulates life, and whether it exists as a fundamental building block of the universe.

In the fight against viruses and other pathogens, scientists are looking beyond genes and proteins to the complex sugars, or glycans, on cell surfaces.

Two ways of approximating the ultra-complicated math that governs quark particles have recently come into conflict, leaving physicists unsure what their decades

Sizing up patternless sets is hard, so mathematicians rely on simple bounds to help answer their questions.

Einstein’s equations describe three canonical configurations of space-time. Now one of these three — important in the study of quantum gravity — has been shown

Anyons don’t fit into either of the two known particle kingdoms. To find them, physicists had to erase the third dimension.

Newly discovered worlds of microbes far beneath the ocean floor, inside old basaltic rocks, could point to a greater likelihood of life elsewhere in the universe.

Vesselin Dimitrov’s proof of the Schinzel-Zassenhaus conjecture quantifies the way special values of polynomials push each other apart.

A lizard that both lays eggs and gives birth to live young is helping scientists understand how and why these forms of reproduction evolved.
