Princeton researchers have tested an AI system that can monitor and control fusion plasma in milliseconds, reacting far faster than a human operator. In one experiment, it predicted a damaging instability about 200 milliseconds before it appeared and ...

Researchers may have found a new way to weaken glioblastoma's defenses against treatment. Blocking a protein called SET prevented tumors from forming in preclinical models, while targeting related proteins made cancer cells more vulnerable to ...

Scientists used Earth's magnetic field and atmosphere as a planet-sized detector to search for some of the lightest proposed forms of dark matter. The approach dramatically improved limits on ultralight axions and uncovered several intriguing dark .. ...

Archaeologists have identified tiny 80,000-year-old projectile points in Uzbekistan that may have been used like arrowheads. Their size, design, and impact damage closely resemble weapons found much later at a Homo sapiens site in France. The ...

A common frog found across Ecuador and Colombia has finally been recognized as its own species after more than a century of mistaken identity. Museum specimens from the 1800s helped scientists reveal that Pristimantis milpe had been hiding in plain . ...

Researchers at UC San Diego have demonstrated that a key cellular enzyme can accurately read an eight-letter genetic alphabet, doubling the four letters used by all known life on Earth. Detailed imaging revealed that RNA polymerase handles synthetic ...

Scientists have uncovered an unusual form of electron behavior in zirconium pentatelluride, a quantum material that can act as both an insulator and a conductor. Under temperatures near absolute zero and magnetic fields reaching 60 tesla, electrons . ...

Scientists have overturned a leading explanation for why male and female bonnethead sharks have differently shaped heads. Instead of males developing a pointed snout at maturity, both sexes actually begin with more pointed heads that become rounder . ...

A substance found in edible sea squirts appeared to reverse several signs of aging in older mice. Plasmalogen supplements improved memory and learning, strengthened connections between brain cells, reduced inflammation, and even helped the mice grow ...

Puerto Rico's normally rainy season has instead brought a severe and fast-growing drought. By August 25, three-quarters of the territory was in at least moderate drought, with extreme drought covering 44 percent and some areas receiving less than 20 ...
