Explore how a basic LED can be used as a tiny solar cell, generating measurable voltage under sunlight. This hands-on electronics project demonstrates the photoelectric effect using a multimeter to ...

At-home LED face masks look like they came straight out of a “Star Wars” movie, but these devices are less sci-fi and more straight-up science-based. But they do have origins in real-life space travel ...

By directly communicating with the brain, a new wireless device could someday help restore lost senses or manage pain without ...

TL;DR: This experiment may not revolutionize telecommunications, but it highlights how accessible these concepts have become outside traditional research labs. Using nothing more than an iPad, a solar ...

Light-emitting diode (LED) light therapy is a cosmetic and medical treatment that uses LED wavelengths to treat various skin conditions, such as acne and psoriasis. You can get this therapy at a ...

Imperial physicists have recreated the famous double-slit experiment, which showed light behaving as particles and a wave, in time rather than space. The experiment relies on materials that can change ...
