Researchers at the Paul Scherrer Institute PSI have succeeded for the first time in recording a light-driven sodium pump from bacterial cells in action. The findings promise progress in developing new methods in neurobiology. The researchers used the new X-ray free-electron laser SwissFEL for their investigations.

Decision support for car buyers: Researchers at the Paul Scherrer Institute have developed a web tool called the Carculator that can be used to compare the environmental performance of passenger cars in detail.

Exotic atoms, in which electrons are replaced by other particles, allow deep insights into the quantum world. After eight years, an international group of scientists have succeeded in a challenging experiment conducted at PSI’s pion source: they created an artificial atom called “pionic helium”.

Researchers from the Paul Scherrer Institute PSI, on behalf of a research project funded by the Swiss Federal Office of Energy (SFOE), have studied how energy consumption by Swiss industry develops depending on energy prices. One result: Price increases for energy usually affect energy consumption only over the long term.

At the Paul Scherrer Institute PSI, researchers have gained insights into a promising material for organic light-emitting diodes (OLEDs). This new understanding at the atomic level will help to develop new lighting materials that have higher light output and also are cost-efficient to manufacture.

With a mobile measurement portal, PSI regularly carries out radioactivity checks on heavy goods vehicles. The purpose of this work, on behalf of the Swiss Federal Office of Public Health, is to discover stray radiation sources.

The new director of the Paul Scherrer Institute has taken up office today. Christian Rüegg aims to further reinforce the leading role of PSI's large research facilities, and thus promote Switzerland as a location for research.

The new beamline at PSI's X-ray free-electron laser SwissFEL will soon be ready for action. In December, Athos delivered laser light for the first time − even sooner than expected, to the delight of the researchers responsible for its construction.

Researchers at the Paul Scherrer Institute PSI have developed a new method to analyse particulate matter more precisely than ever before. With its help, they disproved an established doctrine: that molecules in aerosols undergo no further chemical transformations because they are enclosed in other particulate matter.

Tomographic images from the interior of fossils, brain cells, or computer chips are yielding new insights into the finest of structures. These 3-D images are made possible by the X-ray beams of the Swiss Light Source SLS, together with detectors and sophisticated computer algorithms developed at PSI.

An interview on automotive power systems with Christian Bauer, a scientist at PSI's Laboratory for Energy Systems Analysis who specialises in life cycle and sustainability analyses.

At the ultracold neutron source at PSI, researchers have measured a property of the neutron more precisely than ever before: its electric dipole moment. That's because the search is still on for an explanation of why, after the Big Bang, there was more matter than antimatter.

Using a newly developed imaging method, researchers were able to visualise the magnetic structure inside a material with nanoscale resolution. They succeeded in creating a short "film" consisting of seven movie frames that shows, for the first time in 3D, how tiny vortices of the magnetisation deep within a material change over time.

Petrol, diesel, fuel cell or electric – which is the automobile of the future? A PSI study has examined the overall climate impact of various vehicle engines in use today and also projected it to the year 2040.

Making Switzerland's road traffic fit for the future calls for research, first and foremost. In the large-scale research facilities of PSI, chemists and engineers are investigating how to improve the efficiency of motors and reduce their emissions.

On 10 February, the ESA mission Solar Orbiter is scheduled to start. The Swiss X-ray telescope STIX will be launching too – with detectors developed at PSI.

PSI researchers simulate and model large-scale research facilities as well as experiments, for example, in the materials and biological sciences. Andreas Adelmann, head of PSI's Laboratory for Scientific Computing and Modelling, explains how they do it.

Traditionally, violins are varnished to protect them from humidity and other environmental influences. At PSI, a scientific team has investigated how different coatings affect the instrument. Under no circumstances, they found, should anyone try to do without varnish completely.

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.
