Ice cubes float in water because they’re less dense than the liquid. But a newfound type of ice has a density nearly equal to what’s in your water glass, researchers report in the Feb. 3 Science. If ...

Physics is supposed to be predictable. Drop a ball, and gravity pulls it down. Heat water, and it boils. Light travels in straight lines. Yet throughout history, scientists have encountered ...

Researchers have detailed the physics behind a phenomenon that allows them to create spin in liquid droplets using ultrasound waves, which concentrates solid particles suspended in the liquid. The ...

An elusive form of matter called a quantum spin liquid isn’t a liquid, and it doesn’t spin — but it sure is quantum. Predicted nearly 50 years ago, quantum spin liquids have long evaded definitive ...

“Quantum spin liquids are the exception,” says Gang Chen, Professor of Physics at Fudan University in China. He is describing the theory Soviet theoretical physicist Lev Landau developed to ...
