A Disturbing New Kind of Coral Pollution Is Forming on Japan’s Beaches   2026-09-30 11:11:45 +00:00 ‘Plasticorals,’ pieces of coral rubble fused with plastic, are lasting signs of human activity and may pose a threat to marine ecosystems. While widely manufactured materials like cement and steel degrade over millennia, plastic remains intact long enough that future geologists will likely identify the period from the 1950s onward as a distinct synthetic layer [...] Read more...   The Eruption That Froze Pompeii Is Helping Scientists Measure Time Itself   2026-09-30 10:36:37 +00:00 A nearly 2,000-year-old volcanic disaster is helping scientists refine the clocks used to reconstruct Earth’s history. Nearly 2,000 years after Mount Vesuvius buried Pompeii, the eruption is serving as a calibration point for one of geology’s most widely used dating methods. The key is that the disaster occurred within recorded history. Pliny the Younger described [...] Read more...   Arctic Landslide Triggers 1,580-Foot Tsunami in Alaska   2026-09-30 10:01:57 +00:00 As glaciers retreat, steep Arctic fjords may face rising landslide-tsunami risks that could be reduced through better monitoring and faster warnings. On the evening of August 9, 2025, passengers aboard the Hanse Explorer had just finished photographing and filming South Sawyer Glacier before the vessel began its trip back through the fjord. About 12 hours [...] Read more...   A Simple Pill Could Treat Diabetic Eye Damage Before Vision Is Lost   2026-09-30 00:48:00 +00:00 By targeting the retina’s protective barrier, oral Danegaptide could help treat diabetic eye damage earlier, though its lasting benefits remain to be tested. For millions of people with diabetes, treating vision-threatening eye damage means waiting until vision loss has already begun, at which point doctors must deliver regular anti-VEGF injections directly into the eye. These [...] Read more...   Scientists Identify 485 Pesticide Chemicals With Potential Breast Cancer Links   2026-09-30 00:13:27 +00:00 Researchers found that potential breast cancer-related chemical exposures may come from far more sources than previously recognized. A new study from the Silent Spring Institute has identified hundreds of chemicals in pesticide formulations that could potentially increase breast cancer risk. The list includes both active pesticide ingredients and many so-called “inert” ingredients, which generally receive [...] Read more...   A Drug Made People Burn More Calories – Scientists Aren’t Sure How   2026-09-29 23:38:12 +00:00 In a small study, a drug increased calorie burning without clearly switching on brown fat, the heat-producing tissue scientists hope to harness to help people lose weight. Brown fat burns energy to keep us warm, and researchers hope a drug could put that ability to work against obesity. In a small human study, the drug [...] Read more...   Scientists Discover Striking Orange Killifish in the Amazon’s Threatened Forest Pools   2026-09-29 20:24:55 +00:00 A newly identified Amazonian killifish is known from just three disturbed forest pools, prompting researchers to call for habitat protection. In the Brazilian Amazon, researchers have discovered a brightly colored freshwater killifish named Laimosemion laranja. It belongs to a group in which some species survive seasonal drying as embryos, pausing development entirely and lying dormant [...] Read more...   A Fossil Misidentified for Decades Turns Out To Be a 309-Million-Year-Old Species   2026-09-29 19:49:14 +00:00 A misidentified museum fossil has revealed Jeanerpeton mazonensis, a distinct amphibian ancestor that lived near present-day Chicago 309 million years ago. Jeanerpeton mazonensis, an early ancestor of modern amphibians, looked like a salamander with the squat, chubby build of a frog. Its fossil had been sitting in the Field Museum’s collection under another animal’s name [...] Read more...   “Crawzilla” – Scientists Just Found North America’s Biggest Known Crayfish   2026-09-29 19:14:00 +00:00 The search for North America’s biggest crayfish has turned a friendly rivalry into a scientific question about what limits their growth. A Tennessee bottlebrush crayfish in a West Virginia university collection has taken the top spot in a new ranking of North America’s largest known crayfish. Its carapace, the hard shell covering its head and [...] Read more...   Scientists Identify a Potential New Alzheimer’s Disease Marker   2026-09-29 16:01:55 +00:00 The fluid surrounding the brain may hold another clue to Alzheimer’s, with elevated levels of an enzyme called meprin-β raising the possibility of a new disease indicator. One of the defining features of Alzheimer’s disease is the buildup of beta-amyloid, a protein fragment produced when enzymes cut a larger protein called amyloid precursor protein into [...] Read more...   A Simple Saliva Test Could Offer Clues About Brain Aging   2026-09-29 15:26:53 +00:00 Consistently high and irregular levels of the stress hormone cortisol are linked to faster cognitive decline in older adults. Releasing the hormone cortisol is the human body’s natural way of responding to stress. Because cortisol can cross the blood-brain barrier and bind to receptors in regions responsible for cognition, researchers have long suspected that chronic [...] Read more...   Scientist Reveals 7 of the Strangest Things Coffee Does to Your Body   2026-09-29 14:51:51 +00:00 Some of coffee’s most unusual effects have little to do with caffeine. Its other bioactive compounds can interact with the gut, medications, and nutrients in ways researchers are still trying to understand. Coffee is best known, and perhaps most valued, for its caffeine and its ability to make us feel more awake and alert. But [...] Read more...   Dark Matter May Behave Like Waves and a Distant Quasar Could Prove It   2026-09-29 11:45:38 +00:00 A distant quasar’s distorted images could hold clues to what dark matter is made of. Simulations of dark matter behaving like waves now offer a closer match to where those images appear. When the gravity of a massive object bends light from a more distant source, it creates distorted, multiple images of galaxies in a [...] Read more...   A Hidden Structure on the Moon’s Far Side Could Rewrite Its Magnetic History   2026-09-29 11:10:55 +00:00 New orbital evidence suggests the young Moon may once have generated its own magnetic field from deep within its interior. A buried volcanic structure on the Moon’s far side may provide some of the strongest evidence yet that the young Moon once generated its own magnetic field. Researchers combined gravity data from NASA’s GRAIL mission [...] Read more...   Great News From Enceladus: Saturn’s Icy Moon Just Became Even More Promising for Life   2026-09-29 10:35:42 +00:00 Two new studies suggest that Saturn’s moon Enceladus may be an even more compelling target in the search for extraterrestrial life. If scientists want to search an alien ocean for life, Enceladus offers a rare advantage: the ocean sends samples into space. Saturn’s icy moon hides a global ocean beneath its frozen surface, but researchers [...] Read more...
