Researchers have built a paper-thin chip that converts infrared light into visible light and directs it precisely, all without mechanical motion. The design overcomes a long-standing efficiency-versus-control problem in light-shaping materials. This ...

Physicists have watched a quantum fluid do something once thought almost impossible: stop moving. In experiments with ultra-thin graphene, researchers observed a superfluid--normally defined by its endless, frictionless flow--freeze into a strange .. ...

Researchers have figured out how psoriasis can quietly turn into joint disease for some patients. Immune cells formed in inflamed skin can travel through the blood and reach the joints, where they sometimes trigger inflammation. The key difference .. ...

People who switch to a fully unprocessed diet don't just eat differently--they eat smarter. Research from the University of Bristol shows that when people avoid ultra-processed foods, they naturally pile their plates with fruits and vegetables, ...

Kidney disease often creeps in silently, and many patients aren't diagnosed until major damage is already done. New research shows that even "normal" kidney test results can signal danger if they're unusually low for someone's age. By mapping kidney ...

Kemp's ridley sea turtles, one of the most endangered sea turtle species on Earth, live in some of the noisiest waters on the planet, right alongside major shipping routes. New research reveals that these turtles are especially sensitive to low ...

Researchers have created the first complete map showing how hundreds of mutations in a key cancer gene affect tumor growth. By testing every possible mutation in a critical hotspot, they found that some changes barely boost cancer signals, while ...

Deep inside Earth, two massive hot rock structures have been quietly shaping the planet's magnetic field for millions of years. Using ancient magnetic records and advanced simulations, scientists discovered that these formations influence the ...

Advanced care provided by air ambulance teams was linked to higher survival rates in major trauma patients. Researchers found that more people survived than predicted by standard models, including many with severe injuries and low chances of survival ...

A new metasurface design lets light of different spins bend, focus, and behave independently--while staying sharp across many colors. The trick combines two geometric phase effects so each spin channel can be tuned without interfering with the other. ...
