Ultracold atoms have successfully mimicked a fundamental quantum effect normally found in electronic circuits.

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out that if you manipulate a laser just right, then hit it side-on with another ...

Engineers are turning what used to be a bulky optics bench into something that fits on the tip of a finger, and the latest photonic chips go a step further by splitting a single laser into a ...

Why fast-response, non-contact temperature sensing is needed in biomedical research. How thin, transparent film is used to create the Seebeck effect to measure temperature. The instrumentation ...

Brief blasts of light might make some materials into fleeting superconductors. A new study strengthens the case for this controversial claim, first made more than a decade ago. But while some ...

Low-level light therapy (LLLT) is a non-invasive technique that has been developed to promote tissue regeneration and repair. 1 Interestingly, this therapy has displayed prominent effectiveness in ...

It’s a rare person who can pick up a cheap laser pointer and not wield it like a lightsaber or a phaser, complete with sound effects. There’s just something about the “pew-pew” factor that makes ...

Diabetic retinopathy laser surgery is an in-office treatment that involves making tiny burns in the eye with a beam of light. While it does not correct vision loss that has already occurred, it can ...
