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 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.

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.

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 yea…

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.

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.

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.

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.

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.

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.

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.

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 f…

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 …

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.

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.
