A new Stanford-designed optical amplifier uses energy recycling in a resonator to deliver strong, low-noise amplification with far less power.

Not all PFAS are created equal. New research suggests that some newer “forever chemicals” may accelerate biological aging in vulnerable groups.

The faint scent lingering around ancient Egyptian mummies may hold far more information than previously imagined. By analyzing airborne chemical compounds released from embalmed remains, researchers ...

By freezing a crucial phosphoric acid complex to near absolute zero, scientists uncovered a single, unexpectedly stable structure at the heart of proton transport.

Most of us hear the same advice: move more, eat less fat. Exercise can trim body fat, build muscle, and strengthen the heart. It also raises cardiorespiratory fitness, which is often tracked by how ...
