A property of positronium—an exotic atom consisting of an electron bound to its antimatter partner, a positron—differs significantly from theoretical predictions, a team of physicists reports.

A new experiment shows how facts may depend on the observer.

Network neuroscience could revolutionize how we understand the brain — and change our approach to neurological and psychiatric disorders.

New research investigates whether the “butterfly effect,” a feature of classical physics that describes the high sensitivity of many systems to tiny changes in their starting condition, also applies to quantum mechanics.

Scientists are beginning to discover that the microbes in a sourdough depend not just on the native microbial flora of the baker’s house and hands, but also on other factors like the choice of flour, the temperature of the kitchen, and when and how often the starter is fed.

Experiments at the Large Hadron Collider suggest that muons and other “second-generation particles” obtain their mass from interacting with the Higgs, further strengthening the Standard Model.

David Spergel, Director of the Flatiron Institute's Center for Computational Astrophysics, describes how the combined power of three next-generation facilities could lift the veil on dark matter, dark energy and other cosmic mysteries.

Quantum computers could make encryption a thing of the past, but 15 contenders are trying to prove they have what it takes to safeguard your data.

The third and final mission of the month to the red planet lifted off on Thursday.

Researchers have found that when everything from icebergs to rocks breaks apart, their pieces tend to resemble cubes. The finding suggests a universal rule of fragmentation at scales ranging from the microscopic to the planetary.
