At low temperatures, hydrogen atoms move less like particles and more like waves. This characteristic enables quantum ...

Physicists have created a visible, self-sustaining “time crystal” using swirling liquid crystals that move in endlessly repeating patterns when illuminated. Imagine a clock that runs forever without ...

Scientists have directly measured the minuscule electron sharing that makes precious-metal catalysts so effective. Their new technique, IET, reveals how molecules bind and react on metal surfaces with ...
