Physicists with the University of Illinois Urbana-Champaign's Grainger College of Engineering have identified a new form of superconducting behavior. Experiments on the metal uranium ditelluride reveal that Cooper pairs, the composite electron units responsible for superconductivity, can organize into nonuniform patterns that exist even when the main superconducting phase is absent. https://phys.org/news/2026-10-cooper-pairs-superconducting-critical-temperature.html Superconductivity Sat, 03 Oct 2026 07:00:01 EDT news710216698 The earliest animals may have evolved hundreds of millions of years before their first unmistakable fossils appear in the fossil record, according to a new study led by the University of Oxford.

These particles can have wide-ranging impacts, as seen during this summer's eruption of Mount Etna in Italy, when ash fell over the nearby city of Catania and closed its international airport for weeks. The size of erupted pyroclasts helps determine how far they travel and the hazards they pose. However, exactly how and where they form has remained poorly understood. https://phys.org/news/2026-09-magma-eruptions-microscopic-evidence.html Earth Sciences Mon, 14 Sep 2026 17:10:02 EDT news708622021 Researchers at the Department of Energy's Oak Ridge National Laboratory (ORNL) have developed an artificial intelligence framework that helps researchers use atomic force microscopes to identify important nanoscale features while autonomously targeting the most informative areas of a sample for closer study. https://phys.org/news/2026-09-ai-microscopes-nanoscale-features-sample.html Bio & Medicine Sun, 13 Sep 2026 16:00:01 EDT news708262090 Superconductors are materials that carry electricity with zero resistance below specific temperatures.

We encounter phase transitions throughout everyday life: water freezes into ice, wax melts in the warmth of a flame, and water vapor condenses into droplets on a cold window. In these familiar examples, the atoms themselves rearrange into a new structure, giving the material entirely different properties. https://phys.org/news/2026-08-faint-infrared-insulator-metal-transition.html Condensed Matter Mon, 31 Aug 2026 18:20:03 EDT news707384285 Researchers use tightly focused laser beams to image biological samples, shape materials with microscopic precision and generate displays.
