An old Moon rose this morning, its waning sunlit crescent shining just above the eastern horizon before sunrise.

Researchers have developed a tiny nanolaser that can function inside of living tissues without harming them. 

Hidden deep in a basement at Stanford stands a 10-meter-tall tube, wrapped in a metal cage and draped in wires.

Ammonia, the primary ingredient in nitrogen-based fertilizers, has helped feed the world since World War I.

Antibiotics save countless lives each year from harmful bacterial infections — but the community of beneficial bacteria that live in human intestines, known as the microbiome, frequently suffers collateral damage.

Whatever our hands do—reaching, grabbing or manipulating objects—it always appears simple. 

Gallium nitride, a semiconductor that revolutionized energy-efficient LED lighting, could also transform electronics and wireless communication, thanks to a discovery made by Cornell researchers.

For the first time, NASA’s planet-hunting Transiting Exoplanet Survey Satellite (TESS) watched a black hole tear apart a star in a cataclysmic phenomenon called a tidal disruption event. 

Rapid intensification is a serious challenge for the prediction of hurricane intensity. 

Researchers at Stanford University and the Department of Energy’s SLAC National Accelerator Laboratory say they have found the first, long-sought proof that a decades-old scientific model of material behavior can be used to simulate and understand high-temperature superconductivity ­– an important step toward producing and controlling this puzzling phenomenon at will.
