Researchers in PSI's Laboratory for Scientific Computing and Modelling solve the most complex problems through a combination of theory, modelling, and high-performance computing. With powerful computers, they simulate the smallest molecules or large-scale research facilities.

During investigations of tiny structures with large-scale research facilities, huge amounts of data accumulate at the Paul Scherrer Institute PSI. This data is archived at the CSCS supercomputer centre in Lugano, and the researchers use the supercomputer there for their simulations and modelling.

The Swiss Light Source SLS is set to undergo an upgrade in the coming years: SLS 2.0. The renovation is made possible by the latest technologies and will create a large-scale research facility that will meet the needs of researchers for decades to come.

On 27 November 2019, at the recommendation of the ETH Board, the Federal Council has appointed Christian Rüegg as the new director of the Paul Scherrer Institute PSI. The 43-year-old will take over from Thierry Strässle, who has headed the institute on an interim basis since the beginning of the year. Mr Rüegg is currently head of the Neutrons and Muons Division at the PSI. He will take up his new position on 1 April 2020.

In the service of health, scientists at the Paul Scherrer Institute PSI work with radionuclides and develop agents to treat cancer and to detect tumours. Their research provides support to hospitals and is of great interest to Swiss industry.

Radionuclides open up new options for treating cancer. Christian Rüegg, head of the Research with Neutrons and Muons Division at PSI, explains the significance of the Swiss Spallation Neutron Source SINQ at PSI.

At the neutron source SINQ, PSI researchers are producing special radionuclides that aid in the development of new and more effectively targeted cancer therapies. In this they collaborate closely with the clinics in the surrounding area.

Researchers at the Paul Scherrer Institute PSI have developed a new process with which fibre-reinforced composite materials can be precisely X-rayed. This could help to develop better materials with novel properties.

It is reminiscent of a paper bird made with the help of the Japanese folding art origami: a microrobot that uses the force of magnetic fields to move. In the future, such small machines could be used, for example, in medical operations.

Three researchers share this year's Nobel Prize in Chemistry. They are being honoured for their respective contributions to the development of lithium-ion batteries. Petr Novák of PSI likewise works in this area of research and has known the three laureates personally for decades. In an interview, he tells about sitting directly across from one of them at the crucial moment.

Proton therapy is time-consuming and more costly than conventional radiation therapy, but its accuracy in targeting tumours is unsurpassed. An interview with Damien Weber, head of the Centre for Proton Therapy at PSI.

At PSI, cancer patients receive a therapy that is unique in Switzerland. Bombardment with protons wipes out cancer cells  –  and does so more precisely than with any other form of irradiation.

A PSI research project investigating atmospheric chemistry will be on board the icebreaker Polarstern on 20^th September 2019. Researcher Julia Schmale talks about the upcoming expedition and her role in it.

A 3,500-year-old bronze sculpture is being examined at PSI's SINQ neutron source. This will enable conservators to get a unique view into the interior of the sensational find – and gain insights into how it was made.

Every three years, the World Energy Council explores possible developments of the global energy system under different scenarios. Tom Kober, head of the Energy Economics Group in PSI’s Laboratory for Energy Systems Analysis and one of the lead authors of the study, explains what the individual scenarios mean and how global warming could be mitigated.

The newest large research facility at the Paul Scherrer Institute, SwissFEL, has been completed. In January 2019 it began regular operation. Henrik Lemke, head of the SwissFEL Bernina research group, gives an interim report.

Researchers at the Paul Scherrer Institute PSI, together with colleagues from the pharmaceutical company F. Hoffmann-La Roche AG, have taken an important step towards the development of an active substance against the metastasis of certain cancers. Using the Swiss Light Source SLS, they deciphered the structure of a receptor that plays a crucial role in the migration of cancer cells.

For the first time, PSI researchers have used neutrons to visualise very strong magnetic fields that are up to one million times stronger than Earth's magnetic field. This now makes it possible to study magnets that are already installed in devices such as magnetic resonance tomography systems or alternators.
