Scientists discover why damaged nerves struggle to heal
Scientists have identified a protein that acts like a brake on the nervous system’s ability to repair damaged connections. Blocking AHR helped injured nerve fibers regrow and improved movement and sensation in mice with nerve or spinal cord injuries. The discovery could eventually point toward new treatments designed to shift neurons from simply surviving an injury to actively rebuilding themselves.
Your sleep may be hiding an early clue to Alzheimer’s
Frequent micro-awakenings during sleep were linked to higher genetic risk for Alzheimer’s in healthy middle-aged adults who had no symptoms. The discovery raises the possibility that subtle changes during sleep could offer an early warning signal years before memory problems appear.
NASA’s Roman telescope will see 100 times more sky than Hubble
NASA’s Roman Space Telescope will combine Hubble-like detail with a field of view 100 times larger, giving astronomers a sweeping new way to explore the cosmos. Its observations could uncover hidden planets, map billions of cosmic objects, and help scientists unravel the mysteries of dark matter and dark energy.
Experimental eye drops help blind mice see again
Scientists have created light-activated drugs that helped blind mice perceive light again and restored visually guided behavior without gene therapy, implants, or specialized lighting. Even more intriguingly, two of the most promising compounds worked when administered as eye drops, pointing toward a potentially simple new approach to restoring vision.
A common vape flavoring may disrupt early embryo development
A popular vanilla flavoring in e-cigarettes may interfere with some of the earliest steps of human development. In lab experiments, vanillin caused embryonic stem cells to lose their ability to develop normally and pushed them toward forming only certain types of tissue.
Researchers followed 400,000 kids for 20 years and found a lasting pre-K advantage
A 20-year study of 400,000 students found that children who attended public school pre-K earned better grades and test scores through high school than those in other childcare settings. Better-trained teachers and earlier exposure to structured classrooms may help explain why the advantage lasted so long.
Chimpanzees have been hurling rocks at the same trees for more than a decade
Some chimpanzees in West Africa repeatedly throw rocks at particular trees, creating piles of stones that can remain in use for more than a decade. Researchers think this unusual behavior may be cultural and could serve as a form of communication, territorial signaling, or something more symbolic. Camera traps and audio recordings are now being used to reveal who throws the stones and how nearby chimpanzees respond.
Scientists tested 212 plant-based meat alternatives. Every one contained fungal toxins
Every one of 212 plant-based meat alternatives and drinks tested in the UK contained at least one naturally occurring fungal toxin, though concentrations remained below recommended EU guideline levels. Researchers say the bigger question is whether regularly eating large amounts of these foods could lead to potentially concerning cumulative exposure over time.
Scientists tracked 4,500 animals and found a surprising human effect
Scientists tracking thousands of animals found that our physical presence can reshape where wildlife moves and lives, sometimes as strongly as roads, cities, and other human development. Because different species reacted in very different ways, conservation efforts may need to become much more targeted.
Why scientists asked 1,000 people to bury their underwear
More than 1,000 volunteers buried cotton underwear across Switzerland to help scientists measure how active different soils are. The faster the fabric disappeared, the more biological activity was taking place underground. Gardens showed the fastest decomposition, while lawns had the least, revealing how strongly land management can shape soil life.
Scientists find a huge hidden ice reservoir beneath Utah’s mountains
Beneath the rocky slopes of Mount Timpanogos lies far more ice than anyone walking across the surface might suspect. Researchers used gravity measurements to map the buried glacier in 3D and found it is about 83% ice, with enough frozen water to fill 600 Olympic swimming pools. Their findings suggest rock glaciers form as falling debris buries persistent snow and preserves it for thousands of years. Similar formations around the world may collectively store tens of gigatons of hidden water.
AI searched 100 million possibilities and found a cheaper way to 3D-print a NASA rocket alloy
Researchers used AI to search through more than 100 million possible settings for 3D-printing a high-performance NASA alloy. After only 40 experiments, the system identified six successful configurations, including one that worked at a record-low 500 watts. That could allow GRCop-42, currently difficult and expensive to print, to be made with much more widely available equipment.
Your dislike of eating bugs may be 9,000 years old
Ancient teeth and human DNA are revealing a surprising history of insect eating. Modern humans in northern Eurasia appear to have eaten insects only occasionally, while Neanderthals may have consumed them much more regularly. Populations near the tropics also retained genes that make insect exoskeletons easier to digest.
“I jumped from my chair” – Astronomers spot Betelgeuse’s hidden companion
Astronomers have captured their clearest image yet of Betelgeuse’s long-suspected companion, potentially ending a search that lasted about 100 years. The surprisingly massive hidden star could help explain Betelgeuse’s changing brightness and may influence its future supernova.
Vitamin C won’t prevent most colds, but it may do one small thing
The belief that huge doses of vitamin C can ward off colds was popularized more than 50 years ago by Nobel Prize winner Linus Pauling. Since then, larger studies have found that vitamin C does not prevent most people from catching a cold, although regularly taking it may make severe symptoms slightly shorter or milder.
A mysterious cosmic hum may come from 13-billion-year-old dark stars
Today’s mysterious gravitational-wave background may preserve clues about how the Universe’s first supermassive black holes formed. Descendants of hypothetical Dark Stars could be responsible for a major portion of the signal, offering a surprising new way to investigate cosmic dawn and dark matter.
324-million-year-old fossil reveals how insects conquered land
Ancient fossils suggest insects conquered land through a long amphibious phase rather than making an abrupt jump from water to dry ground. A newly identified 324-million-year-old species still carried paddle-like abdominal limbs, revealing an evolutionary bridge between aquatic ancestors and modern six-legged insects.
Smart nanoparticles light up brain cancer and destroy what surgery misses
Scientists created smart nanoparticles that can both illuminate hidden glioblastoma cells during surgery and destroy microscopic cancer left behind afterward. In mice, the treatment prevented recurrence and led to 100% survival at 60 days, though it has not yet been tested in humans.
Eating more ultra-processed foods may raise prostate cancer risk by 30%
Ultra-processed foods make up a huge share of the American diet, and new research suggests they may carry another serious health risk for men. In a nationally representative study of more than 17,000 U.S. men, those who ate more ultra-processed foods, including soft drinks, packaged snacks, cereals, and processed meats, had roughly 24% to 31% higher risks of prostate cancer after accounting for factors such as age, smoking, race and ethnicity, and poverty status.
Scientists switch on a strange new form of magnetism in an ultrathin material
Scientists have found a surprising way to potentially switch on an unusual form of magnetism in ruthenium dioxide, a material that normally appears nonmagnetic. When the material was made into an ultrathin film only a few atomic layers thick and placed under strain, its electrons developed patterns consistent with altermagnetism, a recently proposed magnetic state with promising uses in advanced electronics.
NASA just used satellites and debris to navigate without GPS
NASA has successfully tested a system that allows satellites to navigate without GPS by using other spacecraft and debris as landmarks in orbit. In just three days, FALCON also improved the known orbits of more than 200 space objects completely autonomously.
Scientists may have finally caught “empty” space changing light
A magnetar with an astonishingly powerful magnetic field may have revealed a quantum effect predicted by Werner Heisenberg nearly 90 years ago. Its light shows signs that supposedly empty space is altering how the light travels, potentially providing the first evidence of vacuum birefringence.
Scientists discover a brain “brake” that can shut down chronic pain
Researchers discovered a brain-based “brake” that can shut down chronic nerve pain in mice by calming an overactive pain circuit. Targeting this system more precisely could one day lead to powerful pain relief without affecting opioid receptors throughout the entire body.
Scientists may have found a shortcut to calorie restriction’s anti-aging benefits
Moderate calorie restriction lowered an immune protein called C3 that appears to help drive chronic inflammation as the body ages. Blocking the same protein reduced age related inflammation in mice, raising the possibility that future treatments could mimic some benefits of calorie restriction without severe dieting.
Manhattan-sized ice island breaks off Greenland’s Petermann Glacier
A Manhattan-sized ice island has broken away from Greenland’s Petermann Glacier after years of growing fractures weakened its floating ice tongue. Scientists expect two more huge sections could soon detach, potentially removing about 22 percent of the remaining ice tongue.
190-year-old DNA reveals a hidden pangolin species
DNA from a nearly 190-year-old museum specimen has helped scientists confirm a distinct Himalayan pangolin species hiding in plain sight in Nepal and northern India. The discovery could give conservationists a powerful new way to trace illegally traded pangolin scales back to the species and regions being targeted by poachers.
NASA’s Roman Space Telescope is ready to hunt thousands of alien worlds
NASA’s Roman Space Telescope is now enclosed inside its Falcon Heavy fairing and nearly ready for launch. Its mission could uncover thousands of exoplanets while helping scientists investigate dark matter, dark energy, and the accelerating expansion of the universe.
Turmeric compound may protect blood vessels from diabetes damage
A compound found in turmeric may help protect blood vessels from some of the damage caused by Type 1 diabetes. In rats, curcumin reduced inflammation, improved cellular signaling, and restored vascular health to levels resembling those of nondiabetic animals. The results hint at a possible new way to reduce the long-term cardiovascular risks of diabetes, but human trials are still needed.
What you eat before age 2 may affect your health 70 years later
Britain’s postwar sugar rationing created a rare natural experiment that let researchers examine how early sugar exposure might affect health decades later. People who experienced more rationing during their first 1,000 days had lower rates of several cancers and showed signs of slower biological aging. They were also still eating less sugar and maintaining healthier diets around age 50.
