Demonstration plant for sustainable aviation fuel inaugurated
On August 20, the inauguration ceremony for a new plant on the PSI campus took place. Here the production of sustainable aviation fuel is being tested: synthetic kerosene produced in an exceptionally efficient way.
How the “unicorn of the seas” got its helix
Synchrotron light reveals for the first time how the spiral form of the narwhal tusk is created by the arrangement of nanometre-sized building blocks.
What a dry meteorite tells us about water on Mars
Neutron and X-ray tomography show where water is bound inside a Martian meteorite – offering new insights into the early history of Mars.

Scientific Highlights from our Centers
Supersampled Scanning Transmission X-ray Microscopy
Researchers from a Swiss-German collaboration have developed a new method for scanning transmission X-ray microscopy substantially reducing the impact of mechanical vibrations and imaging overheads, allowing for routine high-resolution imaging experiments
SDSC and PSI teams jointly explore the AI potential of large-scale infrastructures
Villigen, July 8th, 2026 – To help activate a strategic community around its evolution as a national research infrastructure in data science and AI, the Swiss Data Science Center (SDCS) held a bespoke workshop at the Paul Scherrer Institute (PSI). The event brought together over 30 researchers and data scientists to explore how machine learning (ML) and artificial intelligence (AI) can optimize and accelerate analysis on PSI's large-scale scientific infrastructures. The day featured substantive knowledge exchange and the development of flagship project concepts, aimed at ensuring that ML/AI can empower this vital Swiss facility to advance data-driven science and innovation for the benefit of society.
μSR study of time-reversal symmetry constraints and bulk superfluid response in Li0.95FeAs
We report zero-field (ZF) and transverse-field (TF) muon-spin rotation/relaxation (μSR) measurements on superconducting Li0.95FeAs (Tc ≃ 16.0 K) grown by a high-pressure self-flux method. The ZF-μSR data show ...
