Wir schaffen Wissen – heute für morgen
The Paul Scherrer Institute, PSI, is the largest research institute for natural and engineering sciences within Switzerland. We perform world-class research in three main subject areas: Matter and Material; Energy and the Environment; and Human Health. By conducting fundamental and applied research, we work on long-term solutions for major challenges facing society, industry and science.

Movie directors with extra roles
SwissFEL Storage Large Research FacilitiesData storage devices based on novel materials are expected to make it possible to record information in a smaller space, at higher speed, and with greater energy efficiency than ever before. Movies shot with the X-ray laser show what happens inside potential new storage media, as well as how the processes by which the material switches between two states can be optimised.
Biological light sensor filmed in action
Media Releases Biology SwissFELUsing X-ray laser technology, a team led by researchers of the Paul Scherrer Institute PSI has recorded one of the fastest processes in biology. In doing so, they produced a molecular movie that reveals how the light sensor retinal is activated in a protein molecule. Such reactions occur in numerous organisms. The movie shows for the first time how a protein efficiently controls the reaction of the embedded light sensor.
Hollywood in the Würenlingen woods
SwissFEL Biology Large Research FacilitiesWith the X-ray laser SwissFEL, researchers at PSI want to produce movies of biomolecules in action. This can reveal how our eyes function or how new drugs work.
