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.

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

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 to be inherently unstable.

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

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

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

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.

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 of thinking, has made important progress.

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