Scientists just spotted a mysterious quantum “dance” that could rewrite superconductivity—and reshape future tech. For the first time, researchers have directly visualized the quantum behavior that drives superconductivity, a state in which paired electrons allow electricity to flow with zero resistance at very low temperatures.

But what they observed came as a surprise.

In a study published April 15 in Physical Review Letters, the team captured images of individual atoms forming pairs inside a specially prepared gas cooled to nearly absolute zero — the unreachable limit to how cold anything can get...

Astronomers have spotted something surprising in the far outer Solar System—a faint, short-lived atmosphere clinging to a tiny icy world that shouldn’t be able to hold one at all. The object, called 2002XV93, is far smaller than Pluto, yet observations during a rare stellar alignment revealed its presence through a subtle dimming of starlight. Even more puzzling, calculations suggest this atmosphere should vanish within about 1,000 years unless it’s constantly being replenished.

A group of professional and amateur astronomers in Japan has uncovered evidence that a small, distant object in the outer Solar System is surrounded by a thin atmosp...

Scientists may have found the brain’s “pain switch”—and how to turn it off. New research from the University of Colorado Boulder points to a little-known brain circuit that may determine whether short-term pain fades away or becomes a long-lasting problem. The findings suggest that this pathway plays a key role in turning temporary pain into chronic pain that can persist for months or even years.

The study, conducted in animals and published in the Journal of Neuroscience, focused on a region called the caudal granular insular cortex (CGIC). Researchers found that shutting down this circuit can both prevent chronic pain from developing and stop it after it has already begun.

“Our paper used a variety of state-of-the art methods to define the specific brain circuit crucia...

Many plastic products are designed to be used only once, yet the material itself lasts for years. But a new strategy is addressing this problem by creating products that self-destruct on command, known as living plastics. These materials incorporate activatable, plastic-degrading microbes alongside the polymers. One team reporting in ACS Applied Polymer Materials used two bacterial strains that worked together and completely broke down the material within just six days, without making microplastics.
