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, and affected air…
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 mysteries about how…
A kimchi-derived bacterium can bind to nanoplastics under gut-like conditions and may help carry them out of the body. In mice, the probiotic more than doubled the amount of nanoplastics detected in feces, pointing to a…
Scientists discovered a new frog species in the flooded forests of the western Amazon, distinguishing it from nearly identical relatives through DNA and its unique call. Adenomera varcena highlights how much Amazonian…
A pocket-sized, roughly $100 detector can reveal the invisible stream of cosmic particles constantly passing through Earth and even through our bodies. What began as a student physics project is now being used in major…
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 surprisingly rapid…
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 seeds, while dense…
A natural compound produced by gut bacteria after digesting foods such as pomegranates, walnuts, and berries may help repair and protect the intestinal lining. The discovery reveals a surprising beneficial side of an…
Scientists discovered that brain-cell axons may not be smooth tubes as textbooks have shown for more than a century, but instead naturally resemble strings of tiny pearls. Those pearl-like structures can change with…
Scientists are testing a counterintuitive way to fight mesothelioma, an aggressive asbestos-linked cancer with few effective treatments. A new experimental mesothelioma drug kills cancer cells by disabling PRX3, an…
Scientists have found the first evidence that liquid may have flowed across Pluto’s surface in the recent past. Dark features on the enormous Sputnik Planitia glacier appear consistent with liquid nitrogen rising…
Scientists found that black and green Japanese rice contain unusual, potentially beneficial fats and may be digested more slowly than ordinary white rice. The combination could make these colorful varieties promising…
Scientists discovered a hidden “immune organ” inside the skull that acts as a rapid first responder against brain cancer in mice. Strengthening this local immune defense improved tumor rejection and survival, raising…
Scientists have developed a solar-powered desalination system that turns seawater into fresh water while removing nearly all of the leftover salt as a solid instead of producing harmful brine. The self-cleaning…
Scientists have discovered that some severe genetic disorders linked to rapid aging may be driven not just by damaged DNA, but by the body’s overreaction to that damage. When broken DNA fragments leak into the wrong…
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 South America,…
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, waist size, blood…
Scientists reconstructed videos from the brain activity of mice, producing 10-second clips based only on signals from neurons in the visual cortex. The breakthrough could help reveal how the brain reshapes what we see…
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 Earth’s moon, a Venusian…
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 yields could require…
