'Quiet' light

Spectrally pure lasers lie at the heart of precision high-end scientific and commercial applications, thanks to their ability to produce near-perfect single-color light. A laser's capacity to do so is measured in terms of ...

Virtual lens improves X-ray microscopy

With X-ray microscopes, researchers at PSI look inside computer chips, catalysts, small pieces of bone, or brain tissue. The short wavelength of the X-rays makes details visible that are a million times smaller than a grain ...

Microbes help make the coffee
