Exercise may sharpen the mind by repairing the brain’s protective shield. Researchers found that physical activity prompts the liver to release an enzyme that removes a harmful protein causing the blood-brain barrier to become leaky with age. In ...
Human language may seem messy and inefficient compared to the ultra-compact strings of ones and zeros used by computers—but our brains actually prefer it that way. New research reveals that while digital-style encoding could theoretically compress ...
Scientists at Stanford have unveiled the first-ever global map of rare earthquakes that rumble deep within Earth’s mantle rather than its crust. Long debated and notoriously difficult to confirm, these elusive quakes turn out to cluster in regions ...
A groundbreaking clinical trial is testing whether specially engineered stem cells can help the brain restore its own dopamine production in people with Parkinson’s disease. Because the condition is driven by the gradual loss of dopamine-producing ...
Breathing polluted air may do more than harm your lungs — it could also increase your risk of Alzheimer’s disease. In a sweeping study of nearly 28 million older Americans, researchers found that ...
For decades, scientists have believed that complex life began when two very different microbes joined forces, eventually giving rise to plants, animals, and fungi. But one major puzzle remained: how could these organisms have met if one depended on ...
A giant virus discovered in Japan is adding fuel to the provocative idea that viruses helped create complex life. Named ushikuvirus, it infects amoebae and shows unique traits that connect different families of giant DNA viruses. Its unusual way of ...
A new human study has uncovered how the body naturally turns off inflammation. Researchers found that fat-derived molecules called epoxy-oxylipins rein in immune cells that can otherwise drive chronic disease. Using a drug to boost these molecules ...
A major breakthrough could help save the world’s bananas from a devastating disease. Scientists have discovered the exact genetic region in a wild banana that provides resistance to Fusarium wilt Subtropical Race 4 — a destructive strain that ...
Scientists have taken a major step toward mimicking nature’s tiniest gateways by creating ultra-small pores that rival the dimensions of biological ion channels—just a few atoms wide. The breakthrough opens new possibilities for single-molecule ...
Myopia is skyrocketing around the world, often blamed on endless screen time — but new research suggests the real culprit may be something more subtle. Scientists at SUNY College of Optometry ...
That viral claim that your frontal lobe “isn’t fully developed until 25” turns out to be more myth than milestone. Early brain scans showed that gray matter changes dramatically through the teen years, and because studies stopped around age ...

A newly discovered bacterial duo may be the hidden cause of chronic constipation. The two microbes break down the colon’s protective mucus layer, leaving stool dry and hard — a problem ...

Qubits, the heart of quantum computers, can change performance in fractions of a second — but until now, scientists couldn’t see it happening. Researchers at NBI have built a real-time monitoring ...

Oxford researchers have found a way to visualize one of the most hidden — yet critical — components inside lithium-ion batteries. By tagging polymer binders with traceable markers, they revealed ...

Ocean waves are a vast and steady source of renewable energy, but capturing their power efficiently has long frustrated engineers. A researcher at The University of Osaka has now explored a bold new ...

Sugary drinks may be linked to more than just physical health problems in teens. A new review of multiple studies found a consistent association between high consumption of beverages like soda, ...

Psychedelics can quiet the brain’s visual input system, pushing it to replace missing details with vivid fragments from memory. Scientists found that slow, rhythmic brain waves help shift ...

Couples who intentionally slow down and soak in their happy moments together may be building a powerful shield for their relationship. Researchers at the University of Illinois found that partners ...

Scientists are launching an ambitious global effort to map the “human exposome” — the lifelong mix of environmental and chemical exposures that drive most diseases. Backed by new partnerships ...

Astronomers have uncovered a distant planetary system that flips a long-standing rule of planet formation on its head. Around the small red dwarf star LHS 1903, scientists expected to find rocky ...

A new light-based sensor can spot incredibly tiny amounts of cancer biomarkers in blood, raising the possibility of earlier and simpler cancer detection. The technology merges DNA nanotechnology, ...

A simple shift in your evening routine may give your heart a measurable boost. In a new study, adults who stopped eating and dimmed the lights three hours before bed and extended their overnight fast ...

Scientists have created the most detailed maps yet of how genes control one another inside the brains of people with Alzheimer’s disease. Using a powerful new AI-based system called SIGNET, the ...

A massive star 2.5 million light-years away simply vanished — and astronomers now know why. Instead of exploding in a supernova, it quietly collapsed into a black hole, shedding its outer layers in ...

Microplastics and nanoplastics are now found everywhere on Earth, from ocean depths to agricultural soils and even inside the human body. Yet scientists still struggle to understand what these ...

Scientists at HKUST have unveiled a major leap forward in calcium-ion battery technology, potentially opening the door to safer, more sustainable energy storage for everything from renewable power ...

A robotic arm that moves too quickly can feel creepy. One that moves too slowly feels awkward and unhelpful. In a VR study, researchers found that AI-powered prosthetic arms were best accepted when ...

A sweeping new study has uncovered a troubling mix of hazardous chemicals in popular hair extensions, including products made from human hair. Researchers detected dozens of substances linked to ...

Scientists have developed a new way to read the hidden states of Majorana qubits, which store information in paired quantum modes that resist noise. The results confirm their protected nature and ...

A decades-long study of nearly 200,000 adults challenges the low-carb versus low-fat debate. Both eating patterns were tied to lower heart disease risk when they emphasized whole grains, plant-based ...

Researchers have built a realistic human mini spinal cord in the lab and used it to simulate traumatic injury. The model reproduced key damage seen in real spinal cord injuries, including ...
