Scientists Find a Hidden Biological Link Across Different Forms of Autism   2026-08-21 11:54:12 +00:00 Researchers have identified shared biological changes across different genetic forms of autism, despite the disorder’s extensive genetic diversity. Hundreds of genes have been associated with autism, but scientists still do not fully understand the molecular and cellular processes that drive the condition. A new study published in Nature, led by Gaia Novarino at the Institute [...] Read more...   Scientists Discover a 3.7-Billion-Year-Old Secret of Early Life   2026-08-21 11:19:01 +00:00 Ancient microbes appear to have used molybdenum as far back as 3.7 billion years ago, despite the metal being scarce in Earth’s early oceans. Scientists funded by NASA have found that organisms living on Earth more than 3 billion years ago were already using molybdenum, even though the metal was extremely rare in the environment [...] Read more...   Scientists Revisited a Forest Experiment That Was Forgotten for 30 Years. What They Found Was Astounding   2026-08-21 10:44:13 +00:00 A decades-old experiment in Victoria’s mountain ash forests is challenging assumptions about the trade-offs between timber production and conservation. Should a forest remain untouched, or should some trees be harvested to sustain nearby communities and economies? Australians have debated these competing approaches for decades, often treating conservation and timber production as mutually exclusive choices. Research [...] Read more...   Astronomers Discover a Ghostly River of Stars That Could Reveal Dark Matter   2026-08-21 00:56:41 +00:00 A ghostly ribbon of stars winding around a faint galaxy 115 million light-years away is giving astronomers a rare new way to trace one of the universe’s most elusive ingredients: dark matter. The thin structure surrounds UGC 9050-Dw1, an ultra-diffuse galaxy about 115 million light-years from Earth. Researchers say it is the first known globular [...] Read more...   NASA Is Building a Moon Base – and the First Pieces Are Already Coming Together   2026-08-21 00:21:35 +00:00 More than 20 robotic landings and a new fleet of commercial spacecraft are helping NASA turn its permanent Moon Base plans into reality. NASA is moving forward with plans for a durable Moon Base near the lunar South Pole, where future missions could support scientific research, technology development, and eventually sustained human activity. A major [...] Read more...   Something Mysterious Just Passed Between Earth and a Distant Star   2026-08-20 23:46:31 +00:00 A mysterious object dubbed Phoebe may be a primordial black hole from the early universe, detected only because it briefly magnified the light of a distant star. On the night of 18 December 2019, a star in our satellite galaxy, the Large Magellanic Cloud, briefly got brighter. Not dramatically nor explosively, just a smooth, symmetrical [...] Read more...   This Natural Gut Compound Could Point to Better Treatments for IBD   2026-08-20 19:30:58 +00:00 What if your next meal could help your gut defend itself? Your gut bacteria may be doing more than digesting dinner. They may also be making compounds that help repair the intestine when it is under attack. Researchers at the University of Louisville have uncovered how urolithin A (UroA), a compound produced when certain gut [...] Read more...   Your Liver Runs on a Clock – and It Could Change How We Treat Metabolic Disease   2026-08-20 18:55:51 +00:00 The liver appears to run metabolism on a surprisingly precise timetable, releasing signaling proteins at specific points in the day. Every day, the liver sends signals that help coordinate metabolism throughout the body, but those signals do not appear at random. Researchers at UT Health San Antonio, the academic health center of The University of [...] Read more...   Why Is Colorectal Cancer Rising in People Under 50? New Clues Point to the Environment   2026-08-20 18:20:47 +00:00 Epigenetic fingerprints may help explain how environmental exposures contribute to colorectal cancer in people under 50. Why is colorectal cancer becoming more common in people under 50 when their tumors often lack obvious genetic differences from those diagnosed later in life? A new study suggests part of the answer may be written not in the [...] Read more...   Quantum Fluctuations Break a Crystal’s Symmetry Rules   2026-08-20 15:12:23 +00:00 Electronic fluctuations can act as a resonant bridge between normally separate crystal vibrations, offering a new route to study and control ferroaxial quantum states. Symmetry is a basic rule of the natural world. It explains why some objects appear the same after they are rotated, reflected, or changed in other ways. In materials, symmetry helps [...] Read more...   Researchers Discover a Mysterious New Frog Species in the Amazon   2026-08-20 14:37:26 +00:00 A small frog living in a flooded corner of the Amazon has turned out to be something scientists had never formally recognized before. Some species hide in remote places. Others hide in plain sight. In the western Brazilian Amazon, scientists have identified a new frog species, Adenomera varcena, living in forests that are seasonally submerged [...] Read more...   Scientists Spotted This Mysterious Congo Monkey 18 Years Ago – Now They Finally Know What It Is   2026-08-20 14:02:32 +00:00 A newly identified Congo monkey represents an ancient evolutionary lineage that may already be endangered. A partly hidden monkey appeared in a photograph taken deep in the Democratic Republic of Congo (DRC) in 2008. Researchers saw the animal again a decade later, this time clearly enough to begin investigating whether it represented something science had [...] Read more...   Why Does an Irregular Heartbeat Strike 40 Years Early in Some People?   2026-08-20 11:44:07 +00:00 A hidden genetic threat may trigger atrial fibrillation decades early, raising the risk of stroke before symptoms appear. Atrial fibrillation (AFib) occurs when chaotic electrical signals cause the heart’s upper chambers to beat irregularly and out of sync with the lower chambers. Blood can then collect inside the heart, creating clots that may travel to [...] Read more...   Scientists Reveal How ADHD Could Fuel Creative Thinking   2026-08-20 11:09:58 +00:00 ADHD-related attention patterns may become a source of creativity and focus when supported through structured creative expression. How can ADHD create serious everyday challenges for millions of people while also appearing among highly successful creative figures such as Justin Timberlake and Simone Biles? New research from Constructor University neuroscientist Dr. Radwa Khalil, published in iScience, [...] Read more...   Scientists Find a Surprising Diabetes-Fighting Compound in Turmeric   2026-08-20 10:34:19 +00:00 Curcumin improved blood vessel health in diabetic rats, but human benefits still need to be tested. For people with Type 1 diabetes, controlling blood sugar is only part of the challenge. Over time, persistently elevated glucose can damage blood vessels, helping drive a higher risk of cardiovascular disease even when insulin therapy is carefully managed. [...] Read more...   Archaeologists Discover a 10,000-Year Human History Hidden in the Pyrenees   2026-08-20 01:26:36 +00:00 Carbon-14 dates show that people repeatedly occupied high Pyrenean landscapes throughout the Holocene. The high Pyrenees may look like one of Europe’s last untouched wildernesses, but archaeologists are finding a very different story. For thousands of years, people repeatedly climbed into these rugged landscapes, leaving behind shelters, structures, and traces of activity that stretch across [...] Read more...   Scientists Discover a Surprising Link Between Human Genes and Language   2026-08-20 00:51:40 +00:00 Human migration and isolation appear to shape genetic and language diversity in opposite ways. The finding may seem counterintuitive at first. Regions shaped by migration and population mixing often have higher genetic diversity, so it might seem logical that their languages would be more varied too. Instead, the study finds the reverse pattern. “We were [...] Read more...   Archaeologists Discover a Forgotten 3,000-Year-Old Egyptian Tomb – Now They’re Racing To Save It   2026-08-20 00:16:46 +00:00 A newly discovered Ramesside tomb near Luxor is revealing details about ancient Egyptian burial practices while facing growing danger from flash flooding. Standing at the entrance to a newly uncovered ancient tomb, there is no way to know what waits inside. I recently experienced that mixture of excitement and apprehension while directing an international research [...] Read more...
