New stability rules distinguish quantum phases of matter that an older method wrongly groups together
Most of us recognize basic phases of matter and their properties: solids maintain their shape, liquids flow freely with constant volume, and gases expand to fill their container. Quantum phases, on the other hand, are much harder to categorize, overturning traditional notions of what a phase even is and forcing physicists to rethink their definitions.

Why some young ants start hunting and caring for others early
Some insects, including honeybees and ants, live in highly organized colonies where individuals take on specific roles. In many ant societies, young adult workers typically care for developing young inside the nest before beginning to forage, or search for food, outside it. Some ant species, however, start hunting for food as soon as they reach adulthood, without undergoing a transition period.

New catalyst enables lower-temperature methane conversion with sustained performance
Oxidative coupling of methane (OCM) is a chemical reaction that directly converts methane and oxygen, the main components of natural gas, into higher-value hydrocarbons such as ethane and ethylene. However, the reaction presents a fundamental selectivity challenge.
