PSI develops, builds and operates complex large research facilities. PSI has the world's most powerful muon source, a unique proton and neutron source, an synchrotron of international importance and one of only five X-ray free-electron lasers with hard X-rays in the world. Scientists from all over the world use PSI's large research facilities for their scientific investigations. They are also available to Swiss research and industry for their experiments.

Nano-insights into bone stability
PSI researchers have used a new imaging technique to more precisely assess the nanostructure of bone in the neck of the femur. This could help understand why they fracture relatively often.
Virtual tissue staining in 3-D
Researchers at the Paul Scherrer Institute PSI have developed an AI platform that stains grey micro-CT data like the results of classical histology. This could in the future enable analysis of tissues in three dimensions instead of just thin microscopic sections.
