A new superconductor breaks rules physicists thought were fixed

17:26
A shiny gray crystal called platinum-bismuth-two hides an electronic world unlike anything scientists have seen before. Researchers discovered that only the crystal’s outer surfaces become superconducting—allowing electrons to flow with zero resistance—while the interior remains ordinary metal. Even stranger, the electrons on the surface pair up in a highly unusual pattern that breaks all known r…

Eating more vitamin C can physically change your skin

17:26
Vitamin C doesn’t just belong in skincare products—it works even better when you eat it. Scientists discovered that vitamin C from food travels through the bloodstream into every layer of the skin, boosting collagen and skin renewal. People who ate two vitamin C–packed kiwifruit daily showed thicker, healthier skin. The findings suggest glowing skin really does start from within.

This tiny chip could change the future of quantum computing

17:26
A new microchip-sized device could dramatically accelerate the future of quantum computing. It controls laser frequencies with extreme precision while using far less power than today’s bulky systems. Crucially, it’s made with standard chip manufacturing, meaning it can be mass-produced instead of custom-built. This opens the door to quantum machines far larger and more powerful than anything poss…

This strange magnetism could power tomorrow’s AI

16:53
Scientists in Japan have confirmed that ultra-thin films of ruthenium dioxide belong to a newly recognized and powerful class of magnetic materials called altermagnets. These materials combine the best of two magnetic worlds: they’re stable against interference yet still allow fast, electrical readout—an ideal mix for future memory technology.

Why some people keep making the same bad decisions

16:53
Everyday sights and sounds quietly shape the choices people make, often without them realizing it. New research suggests that some individuals become especially influenced by these environmental cues, relying on them heavily when deciding what to do. The problem arises when those cues start leading to worse outcomes. For certain people, the brain struggles to update these learned signals, causing…

This common food ingredient may shape a child’s health for life

10:38
Scientists discovered that common food emulsifiers consumed by mother mice altered their offspring’s gut microbiome from the very first weeks of life. These changes interfered with normal immune system training, leading to long-term inflammation. As adults, the offspring were more vulnerable to gut disorders and obesity. The findings suggest that food additives may have hidden, lasting effects be…

A strange star near a black hole is defying expectations

10:38
Astronomers have decoded the hidden past of a distant red giant star by listening to tiny vibrations in its light, revealing clues of a dramatic cosmic history. The star, which quietly orbits a dormant black hole, appears to be spinning far faster than it should—and its internal “starquakes” suggest it may have once collided and merged with another star. Even more puzzling, its chemical makeup ma…

How Earth endured a planet-wide inferno: The secret water vault under our feet

7:21
When Earth was a molten inferno, water may have been locked safely underground rather than lost to space. Researchers discovered that bridgmanite deep in the mantle can store far more water at high temperatures than previously believed. During Earth’s cooling, this hidden reservoir could have held water volumes comparable to today’s oceans. Over time, that buried water helped drive geology and re…

Back from the dead: “Extinct” fish rediscovered in a remote Bolivian pond after 20 years

7:21
A tiny fish long feared lost has resurfaced in Bolivia, offering a rare conservation success story amid widespread habitat destruction. Moema claudiae, a seasonal killifish unseen for more than 20 years, was rediscovered in a small temporary pond hidden within a fragment of forest surrounded by farmland. The find allowed scientists to photograph the species alive for the first time and uncover ne…

A surprising brain cleanup reduced epileptic seizures and restored memory

7:21
A new study suggests temporal lobe epilepsy may be linked to early aging of certain brain cells. When researchers removed these aging cells in mice, seizures dropped, memory improved, and some animals avoided epilepsy altogether. The treatment used drugs already known to science, raising the possibility of quicker translation to people. The results offer new hope for patients who do not respond t…

Astronomers discover one of the Universe’s largest spinning structures

25.prosince
Scientists have discovered a giant cosmic filament where galaxies spin in sync with the structure that holds them together. The razor-thin chain of galaxies sits inside a much larger filament that appears to be slowly rotating as a whole. This coordinated motion is far stronger than expected by chance and hints that galaxy spin may be inherited from the cosmic web itself. The finding opens a new …

Oceans are supercharging hurricanes past Category 5

25.prosince
Deep ocean hot spots packed with heat are making the strongest hurricanes and typhoons more likely—and more dangerous. These regions, especially near the Philippines and the Caribbean, are expanding as climate change warms ocean waters far below the surface. As a result, storms powerful enough to exceed Category 5 are appearing more often, with over half occurring in just the past decade. Researc…

This popular painkiller may do more harm than good

25.prosince
Tramadol, a popular opioid often seen as a “safer” painkiller, may not live up to its reputation. A large analysis of clinical trials found that while it does reduce chronic pain, the relief is modest—so small that many patients likely wouldn’t notice much real-world benefit. At the same time, tramadol was linked to a significantly higher risk of serious side effects, especially heart-related pro…

A Christmas tree 80 light-years wide appears in space

25.prosince
This Christmas, astronomers are highlighting a spectacular region of space that looks remarkably like a glowing holiday tree. Known as NGC 2264, this distant star-forming region sits about 2,700 light-years away and is filled with newborn stars lighting up clouds of gas and dust. The stars form a triangular shape called the Christmas Tree cluster, crowned by the dramatic Cone Nebula and wrapped i…

Scientists found a way to restore brain blood flow in dementia

25.prosince
A new study suggests that dementia may be driven in part by faulty blood flow in the brain. Researchers found that losing a key lipid causes blood vessels to become overactive, disrupting circulation and starving brain tissue. When the missing molecule was restored, normal blood flow returned. This discovery opens the door to new treatments aimed at fixing vascular problems in dementia.
