Detecting the hidden magnetism of altermagnets
Altermagnets are a newly recognized class of antiferromagnets whose magnetic structure behaves very differently from what is found in conventional systems. In conventional antiferromagnets, the sublattices are linked by simple inversion or translation, resulting in
China's durian craze has turned this tropical fruit into a tool of diplomacy
Distinctive in taste and famously divisive, durian is not everyone's choice of fruit. This was certainly the case for some Chinese explorers when they first encountered it during the Ming Dynasty's early maritime voyages.
What 38 million obituaries reveal about how Americans define a 'life well lived'
Obituaries preserve what families most want remembered about the people they cherish most. Across time, they also reveal the values each era chose to honor.
Elusive wild cat feared extinct rediscovered in Thailand
An elusive wild cat long feared extinct in Thailand has been rediscovered three decades after the last recorded sighting, conservation authorities and an NGO said Friday.
Mathematicians spent 2025 exploring the edge of mathematics
Somewhere at the edge of mathematics lurks a number so large that it breaks the very foundations of our understanding - and in 2025 we came a step closer to finding it
16,000 fossil footprints in central Bolivia reveal dinosaur behavior
Legend once had it that the huge, three-toed footprints scattered across the central highlands of Bolivia came from supernaturally strong monsters—capable of sinking their claws even into solid stone.
One of World’s Rarest Cats Has Finally Resurfaced
Behold the first sightings of a flat-headed cat in Thailand in 30 Years The post One of World’s Rarest Cats Has Finally Resurfaced appeared first on Nautilus .
Chinchorro mummification may have originated as a form of art therapy, study suggests
In a recent study published in the Cambridge Archaeological Journal, Dr. Bernardo Arriaza argues that the practice of artificial mummification among the Chinchorro people may have evolved as a response to high infant mortality rates, with the artistic mummification of the dead
How did Bronze Age plague spread? A sheep might solve the mystery
In the Middle Ages, a plague killed a third of Europe's population. Fleas carried the plague bacterium, Yersinia pestis, transmitting the Black Death from infected rats to millions of people.
Eating more vitamin C can physically change your skin
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
A new superconductor breaks rules physicists thought were fixed
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
This tiny chip could change the future of quantum computing
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
Gemini and Blanco telescopes unlock clues to origin of longest gamma-ray burst ever observed
Gamma-ray bursts (GRBs) are among the most powerful explosions in the universe, second only to the Big Bang. The majority of these bursts are observed to flash and fade within a few seconds to minutes. But on 2 July 2025, astronomers were alerted to a GRB source that was
This strange magnetism could power tomorrow’s AI
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
Flaring black hole whips up ultra-fast winds
Leading X-ray space telescopes XMM-Newton and XRISM have spotted a never-seen-before blast from a supermassive black hole. In a matter of hours, the gravitational monster whipped up powerful winds, flinging material out into space at eye-watering speeds of 60,000 km per second.
These medical breakthroughs and advances gave patients new hope in 2025
Advances delivered what may feel like medical miracles, including the first bladder transplant, a lifesaving personalized gene therapy and more.
Astronomers explore the double nucleus of galaxy NGC 4486B
Using the James Webb Space Telescope (JWST), an international team of astronomers has observed an elliptical galaxy known as NGC 4486B. Results of the observational campaign, published Dec. 16 on the arXiv preprint server, deliver important insights into the properties of the
Why some people keep making the same bad decisions
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
2025's best photos of the natural world, from volcanoes to icebergs
A village buried by a landslide, the world’s largest tidal bore and the aftermath of ferocious storms and wildfires appear in our pick of images from environment stories this year
SpaceX Could Go Public in 2026. What Does That Mean for Space Exploration?
SpaceX is mulling an IPO in 2026. Here’s how that could affect its work with NASA and the push to put humans on Mars

Record-breaking objects can tell us about the most powerful events in the cosmos—sometimes
12 of the Best Interviews Scientific American Did In 2025
From an interview with author Mary Roach to a chat with cardiologist Eric Topol, here are 12 of the most eye-opening conversations we had this year
Was 2025 the year we found signs of past life on Mars?
Tantalising signs of past microbial life showed up on Mars this year, but to truly know whether they contain the answer to the biggest question in the universe, we will need to bring samples back to Earth

This common food ingredient may shape a child’s health for life
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
'Spectacular' progress has been made towards useful quantum computers
At the Q2B Silicon Valley conference, scientific and business leaders of the quantum computing industry hailed "spectacular" progress being made towards practical devices – but said that challenges remain
A strange star near a black hole is defying expectations
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
How Earth endured a planet-wide inferno: The secret water vault under our feet
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
A surprising brain cleanup reduced epileptic seizures and restored memory
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
Back from the dead: “Extinct” fish rediscovered in a remote Bolivian pond after 20 years
