Cats may identify one another through a surprisingly durable chemical “calling card” made from 13 unusual fatty acids in their urine. The compounds appear linked to mysterious fat droplets in the kidneys and may represent a scent-recognition ...
Researchers may have solved a long-running mystery surrounding the Dead Sea Scrolls by proposing that the Qumran sect really did use its distinctive 364-day calendar. Its perfectly ordered 52-week system kept holidays on the same weekdays, but it ...
Scientists have developed ultra-bright nanoparticles that can detect tiny amounts of chemicals and distinguish between molecules that look almost identical. The technology could one day provide a cheaper way to catch dangerous drug impurities or ...
A decade-long NIST experiment has produced a new measurement of the universal gravitational constant that differs unexpectedly from another leading result, deepening a 225-year-old physics puzzle. ...
Ancient DNA reveals that plague repeatedly returned to Europe for more than 400 years after the Black Death, evolving into new lineages and spreading through trade, migration, and war. Researchers ...
Chemical clues preserved inside fossilized T. rex teeth reveal that the dinosaur maintained a body temperature of about 97 degrees Fahrenheit, almost identical to humans. The finding provides direct evidence that the giant predator was warm-blooded, ...
Physicists have detected strong evidence that heavy, fleeting Z bosons can become quantum entangled during Higgs boson decays at CERN’s Large Hadron Collider. The result shows that Einstein’s ...
Nearly three decades of Hurricane Hunter data reveal four features that can help a tilted tropical cyclone straighten its circulation and become capable of intensifying. The findings could give ...
A chemical that stops drywood termites from building new exoskeletons killed about 95% of colonies in testing, offering a potentially safer alternative to traditional fumigation. Because termites eventually have no choice but to molt, the treatment ...
A massive crater on Mars’ moon Phobos may hide a dense region of compressed material that could reveal whether the moon is a captured asteroid or debris from an ancient impact on Mars. Japan’s upcoming MMX sample return mission could provide the ...
A deep-sea microbe uses an exceptionally heat-resistant enzyme to turn atmospheric nitrogen into ammonia at temperatures that would destroy most proteins. Its unusual structure and a newly observed reaction state may reveal an ancient, shared ...
A single-celled organism can shrink to one-quarter of its length in milliseconds using a remarkable calcium-powered protein “fishnet.” Scientists hope its unusual machinery could inspire artificial muscles capable of moving far faster than ...

Astronomers have confirmed a Jupiter-size planet less than a million years old, making Elias 2-24 b the youngest known planet and giving scientists a rare look at a world still being born. Its ...

New supercomputer simulations suggest JWST’s puzzling Little Red Dots are rapidly growing black holes from the early Universe. Extreme radiation may have helped create unusually massive black hole ...

Arctic sea ice may move in unexpected ways because individual ice floes are constantly colliding and transferring energy. Researchers found that this simple process can explain several long-standing ...

A newly identified 240-million-year-old animal from Tanzania is forcing scientists to rethink the early dinosaur timeline. Dinodontosaurus isiyavamanda belongs to a group previously known only from ...

Eating four to six servings of whole grains a day may deliver meaningful benefits for heart health, according to a large review of 87 clinical trials. Researchers found improvements in body weight, ...

Venus may have once had a moon, but new research suggests the planet’s incredibly slow rotation could have doomed it. Computer simulations showed that instead of gradually drifting away like ...

U.S. irrigation produces some greenhouse gas emissions, but new research suggests it prevents vastly more by allowing farmers to grow more food on less land. Without irrigation, replacing lost crop ...

A feather discovered inside 66-million-year-old fossilized dinosaur poop may help explain why modern birds survived the asteroid catastrophe. The extinct bird it came from had more primitive ...

Researchers have found a way to perform certain quantum operations more than 1,000 times faster, cutting thousands of repeated control cycles down to just one. The advance could reduce errors and ...

A major Ontario study found 24 common medication chains in which one drug’s side effects can be mistaken for a new medical problem, leading to another prescription. Researchers say closer ...

Researchers analyzing data from more than 1.9 million people found that ADHD is associated with substantially higher rates of digestive problems. People with ADHD had nearly double the odds of ...

Anak Krakatau erupted for more than 24 hours in early September, sending volcanic ash up to 50,000 feet into the atmosphere. The ash cloud shut down eight airports, disrupted nearly 3,000 flights, ...

The James Webb Space Telescope has revealed surprising changes in the rings around Chariklo, a small object orbiting between Saturn and Uranus. Over just a few years, its inner ring became more ...

Nighttime light exposure was linked to thicker, stiffer heart chambers and early signs of reduced heart function in a study of more than 11,000 people. The findings suggest that keeping bedrooms ...

Scientists have directly observed how two negatively charged DNA molecules can pair up despite normally repelling each other. Positively charged metal ions appear to bridge the gap, helping matching ...

Researchers have created a foam-based material that produces intense whiteness and water repellency without titanium dioxide pigments or PFAS chemicals. Inspired by natural structures in snow, ...

Ancient human remains from Sulawesi suggest people were habitually using the psychoactive betel nut as far back as 25,000 years ago. Researchers found both unusual tooth wear and traces of arecoline, ...

Scientists have discovered that the Moon-forming collision may have depended heavily on how hot and physically strong early Earth and Theia were. New simulations found that some impacts create the ...

UCLA researchers developed ready-made cancer-fighting T cells from cord blood stem cells that can attack solid tumors through two separate detection systems. In mice, a single dose controlled cancer ...

Britain’s towering Devil’s Arrows were built from 25-tonne stones hauled at least 18 kilometers from Brimham Rocks around 4,000 years ago. The discovery reveals an astonishing feat of prehistoric ...
