Scientists at the Paul Scherrer Institute PSI have, for the first time, demonstrated a technique that synchronizes ultrashort ...

Dermatologists explain the science behind wildly popular treatments like red light therapy, which is now available at home—for a steep price. Full-face LED masks like this one can cost up to several ...

Researchers have built a new platform that produces ultrashort UV-C laser pulses and detects them at room temperature using ...

It turns out the "10-year lifespan" printed on your LED box is often a total fantasy. I spent years falling for the marketing, only to end up standing on a ladder every six months replacing bulbs that ...

Exclusive Delayed communications from a hospital trust to GP practices have led to cancer diagnoses not being recorded and to other serious patient safety issues, GPs have warned. GPs in Sheffield ...

A pulse oximeter measures blood oxygen levels at home and in healthcare settings. Abnormally low readings on a pulse oximeter might require medical care, especially if they are below 92%. Skin color ...

A reboot of the classic disaster film has caused a surge in amateur storm chasing. So what is it really like to chase tornadoes? Professional storm chasers monitor a tornado in Kansas, where tornadoes ...
