Many biologically important molecules change shape when stimulated by UV radiation. Although this property can also be found ...

Located in Hamburg, Germany, this cutting-edge facility is home to the world’s largest and most powerful X-ray laser. Axions are hypothetical, tiny, and light particles. XFEL facility has a 3.4 ...

While [Micah] want’s to use these Blu-ray drives for laser graffiti, there are a number of other slightly more useful reasons for the build. With a DVD drive, you can hold a red blood cell in ...

The hard X-ray FEL has come of age. A free-electron laser is not like other lasers. It works by forcing a beam of electrons, travelling at nearly the speed of light, to oscillate in a long ...
