Inspired by the shape-shifting skin of octopuses, Penn State researchers developed a smart hydrogel that can change appearance, texture, and shape on command. The material is programmed using a special printing technique that embeds digital ...

Quantum computers struggle because their qubits are incredibly easy to disrupt, especially during calculations. A new experiment shows how to perform quantum operations while continuously fixing errors, rather than pausing protection to compute. The ...

Scientists have found that ancient Martian lakes could have survived for decades despite freezing air temperatures. Using a newly adapted climate model, researchers showed that thin, seasonal ice could trap heat and protect liquid water beneath. ...

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 .. ...

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 ...

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. ...

A new optical device allows researchers to generate and switch between two stable, donut-shaped light patterns called skyrmions. These light vortices hold their shape even when disturbed, making them promising for wireless data transmission. Using a ...

Researchers have found that manganese, an abundant and inexpensive metal, can be used to efficiently convert carbon dioxide into formate, a potential hydrogen source for fuel cells. The key was a clever redesign that made the catalyst last far longer ...

Astronomers have produced the most detailed map yet of dark matter, revealing the invisible framework that shaped the Universe long before stars and galaxies formed. Using powerful new observations from NASA's James Webb Space Telescope, the research ...
