Ice XXI: Scientists use X-ray laser to identify new room-temperature phase Ice cream comes in many different flavors. But even pure ice, which consists only of water molecules, has been discovered to exist in more than 20 different solid forms or phases that differ in the arrangement of the molecules. The phases are named with Roman numerals, like ice I, ice II or ice III. Now, researchers led by scientists from the Korea Research Institute of Standards and Science (KRISS) have identified and described a new phase called ice XXI. The results are published in the journal Nature Materials. /news/2025-10-ice-xxi-scientists-ray-laser.html Condensed Matter Soft Matter Fri, 10 Oct 2025 11:44:04 EDT news679315441 Biohybrids: Pioneering sustainable chemical synthesis at the energy-environment frontier With global energy demand climbing and climate challenges intensifying, researchers are exploring transformative new ways to make chemical manufacturing sustainable. /news/2025-09-biohybrids-sustainable-chemical-synthesis-energy.html Biochemistry Materials Science Wed, 24 Sep 2025 09:01:03 EDT news677923261 Researchers are first to image directional atomic vibrations Researchers at the University of California, Irvine, together with international collaborators, have developed a new electron microscopy method that has enabled the first-ever imaging of vibrations, or phonons, in specific directions at the atomic scale. /news/2025-09-image-atomic-vibrations.html Condensed Matter Fri, 19 Sep 2025 12:11:57 EDT news677502711 Geologists discover where energy goes during an earthquake The ground-shaking that an earthquake generates is only a fraction of the total energy that a quake releases.
