New observations reveal that the relationship between ultraviolet and X-ray light in quasars has changed over billions of years. This unexpected shift suggests the structure around supermassive black holes may evolve with time, challenging a decades-old assumption.

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
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.
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.
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.
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
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.
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 .
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
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.
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 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
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
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
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
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.
Advances delivered what may feel like medical miracles, including the first bladder transplant, a lifesaving personalized gene therapy and more.
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
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
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 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
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
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

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
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
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
