How photons change chemistry

The quantum nature of light usually does not play an important role when considering the chemical properties of atoms or molecules. In an article published in the Proceedings of the National Academy of Sciences scientists ...

Capturing an elusive spectrum of light

Researchers led by EPFL have built ultra-high quality optical cavities for the elusive mid-infrared spectral region, paving the way for new chemical and biological sensors, as well as promising technologies.

Herbivorous mammals have bigger bellies

As an international study conducted by the University of Zurich based on 3-D reconstructions of animal skeletons reveals for the first time: Herbivorous mammals have bigger bellies than their usually slim carnivorous counterparts. ...
