| Brain Scans Reveal a Surprising Dopamine Difference in Autism |
|
|
2026-09-01 11:12:48 +00:00
 By analyzing three different types of brain scans, researchers uncovered new clues about the biological processes linked to autism. The results point to the dopamine system as a potentially important part of autism biology. Autism is associated with differences across several systems in the brain, but understanding how those differences connect has been difficult. Researchers [...]

| The Brain Makes New Neurons Even in Adulthood. Depression May Stop It |
|
|
2026-09-01 10:37:54 +00:00
 Depression was linked to stalled adult neurogenesis and widespread molecular changes in hippocampal memory circuits. A small stream of new neurons continues to appear in the adult hippocampus even though most of the brain’s roughly 100 billion neurons are formed before birth. Research from Columbia University Vagelos College of Physicians and Surgeons suggests that this [...]

| Scientists Discover a Hidden “Immune Organ” Inside the Skull |
|
|
2026-09-01 10:02:57 +00:00
 Researchers discovered lymph node-like immune hubs inside skull bone marrow that appear to act as rapid-response centers for the brain. For decades, the brain was thought to operate largely apart from the immune system. Researchers at Washington University School of Medicine in St. Louis have now identified lymph node-like structures inside the skull bone marrow [...]

| This Metallic Green Beetle Is Quietly Killing Ash Trees Across Texas |
|
|
2026-08-31 23:43:46 +00:00
 The emerald ash borer is an invasive wood-boring beetle that has killed hundreds of millions of ash trees across North America. Emerald ash borer has reached five more Texas counties, extending the range of an invasive beetle that has already killed hundreds of millions of ash trees across North America. Adults are small, metallic green [...]

| A 15-Day Window Could Decide the Fate of California’s Most Endangered Salmon |
|
|
2026-08-31 23:08:42 +00:00
 Chinook salmon need cold water during the first weeks of development for their eggs to survive. California’s most endangered salmon now survive as a single population in the Sacramento River, far from much of the cold mountain habitat where they once spawned. Sacramento River winter-run Chinook salmon have averaged only a few thousand returning adults [...]

| Red Meat Helped Build Humanity, Now It May Be Harming Us |
|
|
2026-08-31 22:33:03 +00:00
 Red meat may have helped shape the human species, but today’s appetite for it is taking a growing toll on human health and the planet. An interdisciplinary review published in The Quarterly Review of Biology examines how red meat changed from a valuable source of concentrated nutrition into a contributor to chronic disease and ecological [...]

| Scientists Discover a Brain Signal Linked to Severe Suicidal Thoughts |
|
|
2026-08-31 19:27:47 +00:00
 P2RX7 may be linked to severe suicidal thoughts and recovery, but researchers still need to confirm the pattern in living people. Severe suicidal thoughts may leave a detectable biological signal in the brain, and that signal could also change when people recover. Researchers at the Netherlands Institute for Neuroscience have identified a receptor that may [...]

| A Tiny Wireless Device Could Transform How Chronic Pain Is Treated |
|
|
2026-08-31 18:52:07 +00:00
 A seed-sized injectable device could make nerve stimulation therapies simpler, safer, and more accessible. Researchers at NYU Abu Dhabi, working with Cleveland Clinic Abu Dhabi, have created a tiny injectable device that could offer a less invasive way to treat chronic pain and movement disorders. The device is designed to control nerve activity without surgery, [...]

| Sugary Drinks Linked to 145% Higher Risk of Gastric Cancer |
|
|
2026-08-31 18:17:02 +00:00
 Adults who drank sugar-sweetened beverages every day had a higher observed risk of gastric cancer, while artificially sweetened drinks showed no such association. Sugary drinks are part of the daily routine for many Americans, with approximately 65% of U.S. adults reporting that they consume at least one sugar-sweetened beverage each day. Researchers at the Mass [...]

| How Insects Conquered Land Was Stranger Than Scientists Thought |
|
|
2026-08-31 15:04:43 +00:00
 Before insects ruled the skies and reshaped life on land, some of their ancestors may have paddled through shallow coastal water on rows of abdominal limbs. Today, insects occupy nearly every terrestrial environment and account for more described species than any other animal group. Their rise helped transform early land ecosystems by moving nutrients, breaking [...]

| A 250-Year-Old Heat Mystery Leads to a Surprising Discovery About Human Sweat |
|
|
2026-08-31 14:29:29 +00:00
 In extreme heat, sweat can lose much of its cooling power for a reason scientists have largely overlooked: the air directly above the skin can become almost perfectly still. Arizona State University researchers have identified a physical effect that can reduce sweat evaporation by more than half in hot, dry, windless conditions. The finding could [...]

| Thousands of Giant Whales Are Suddenly Flooding Into an Arctic “Feeding Frenzy” |
|

2026-08-31 13:54:53 +00:00
 Thousands of enormous whales are turning the waters off East Greenland into an immense feeding ground that barely existed a generation ago. Fin whales, humpback whales, and common minke whales now gather along a coastline where all three were once rarely seen. Researchers say warmer water, retreating sea ice, and a major relocation of their [...]

2026-08-31 10:53:32 +00:00
 Researchers built a dataset of 1,202 records from 448 papers and screened about 150 million virtual compositions to identify potential materials for future MLCCs and electric vehicle electronics. Finding a new electronic material can mean searching through an almost limitless number of possible chemical combinations. Researchers at Seoul National University have used artificial intelligence to [...]

| A Major Quantum Computing Problem May Finally Have an Answer: Can We Trust the Results? |
|
|
2026-08-31 10:18:24 +00:00
 Researchers can now put numerical error limits on quantum simulations, showing how much confidence to place in their results. As quantum simulators become powerful enough to tackle problems beyond the reach of conventional computers, a difficult question follows: how can researchers know whether their answers are accurate? When classical calculations are still possible, the two [...]

| Researchers Have Discovered a New Way To Reduce Chronic Nerve Pain |
|
|
2026-08-31 00:33:57 +00:00
 A cancer-linked protein called BRAF may help drive chronic nerve pain, and existing cancer drugs targeting it reduced pain sensitivity in preclinical models. Chronic nerve pain can persist long after an injury and often responds poorly to standard pain medications. Researchers at The University of Texas MD Anderson Cancer Center now report evidence that BRAF, [...]
