Sleep and the Brain: An analysis of 57 brain-imaging studies links several sleep disorders to structural changes in areas involved in attention, motivation and decision-making, potentially guiding earlier diagnosis and tailored treatment. Sharper X-rays: Researchers produced record-intensity hard X-ray flashes lasting 300 attoseconds, offering a new way to probe electron motion in atoms and molecules. AI Chip Cooling: Entegris is expanding into diamond materials and partnering with Element Six to develop cooling technologies for increasingly heat-intensive AI chips. Pollution Pathways: Tijuana River contaminants can travel through coastal waters before affecting San Diego’s air, reaching areas more than 20 miles from the river mouth, a study finds. Crop Resilience: Scientists have engineered rice that resists a devastating crop disease, a potential tool for protecting harvests. Space Discoveries: Researchers identified an unusual rock in a Martian meteorite and reported the first garnet found on Mars, though its planetary origin remains uncertain. New Frontiers: Separate studies suggest Mars may host habitable volcanic vents, while research into Earth’s early history raises the possibility that the planet made some of its own water. Fighting Superbugs: Scientists are exploring how viruses can be used against dangerous bacterial infections.
