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 quality as far away as Jakarta. NASA ...

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 quickly the ice moves and ...

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 surprising potential use for . ...

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 biodiversity remains hidden even ...

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 experiments, balloon missions, ...

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 formation challenges leading theories ...

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 surrounding gas allowed them to .. ...

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 inflammatory pathway and could .. ...

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 neural activity and may help ...
