For the first time, scientists have captured how complex molecules change shape when exposed to UV light—an ultra-fast ...

Tiny molecules that can change their shape ... that bend in response to visible wavelengths of light and revert back in the presence of UV light. “We were inspired by the way bacteria propel ...

Many biologically important molecules change shape when stimulated by UV radiation ... with the help of X-ray light. The method opens up exciting new ways of analyzing many other molecules.

Here's how these UV light sanitizers actually work. UV light is highly effective at killing germs The three main types of UV rays are UVA, UVB, and UVC. Because UVC rays have the shortest ...
