On 4 April 2014 SBB is to launch a new minibar model in its Intercity trains. A fuel cell system including know-how of the Paul Scherrer Institute will also be on board. It will ensure that despite the limited space the minibar will have enough power to brew capuccinos and latte macchiatos, too.
Scientists have used a particle accelerator to obtain high-speed 3D X-ray visualizations of the flight muscles of flies. The team from Oxford University, Imperial College, and the Paul Scherrer Institute (PSI) developed a groundbreaking new CT scanning technique at the PSI’s Swiss Light Source to allow them to film inside live flying insects. The movies offer a glimpse into the inner workings of one of nature’s most complex mechanisms, showing that structural deformations are the key to understanding how a fly controls its wingbeat.
Researchers from ETH Zurich and the Paul Scherrer Institute PSI demonstrate how the magnetic structure can be altered quickly in novel materials. The effect could be used in efficient hard drives of the future.
Materials research, particle physics, molecular biology, archaeology à for the last forty years, the Paul Scherrer Institute’s large-scale proton accelerator has made top-flight research possible in a number of different fields.
Superconductivity and magnetic fields are normally seen as rivals à very strong magnetic fields normally destroy the superconducting state. Physicists at the Paul Scherrer Institute have now demonstrated that a novel superconducting state is only created in the material CeCoIn5 when there are strong external magnetic fields. This state can then be manipulated by modifying the field direction. The material is already superconducting in weaker fields, too. In strong fields, however, an additional second superconducting state is created which means that there are two different superconducting states at the same time in the same material.
PSI-researcher Martin Gysel receives prestigious European funding (ERC Consolidator Grant) for his studies on the role of soot in cloud formation and global warming.
As part of the Energy Strategy 2050 the Swiss government and parliament have decided to increase support for energy research in Switzerland. This includes the setting up of seven interuniversity networked Swiss Competence Centres in Energy Research (SCCERs). In the SCCERs ETH Domain institutions, the universities and the universities of the applied sciences are to join forces with industrial partners to develop new competencies and solutions in the decisive action areas of the shift in energy policy. The Paul Scherrer Institute PSI will act as the leading house in two of the SCCERs à storage and biomass à that have already been given the green light. They will begin their work in 2014.
Botox is a highly dangerous toxin that causes paralysis. In cosmetic applications it is used to temporarily eliminate wrinkles and in medicine as a treatment for migraine or to correct strabismus. An international research team has now established how the toxin molecule binds to the neuron whose activity is then blocked by the poison. The findings may be useful for the development of improved drugs with a lower risk of overdosage.
Above the transition temperature, some electrons in the superconducting material La1.77Sr0.23CuO4 behave as if they were in a conventional metal, others as in an unconventional one à depending on the direction of their motion. This is the result of experiments performed at the SLS. The discovery of this anisotropy makes an important contribution towards understanding high-temperature superconductors. The effect will also have to be taken into account in future experiments and theories of high-temperature superconductors.
A new mammography procedure that could generate substantial added value for the diagnosis of breast cancer in medical practice has just been published in the scientific journal Investigative Radiology. The method was developed at PSI in cooperation with the Certified Breast Centre at the Kantonsspital (cantonal hospital in) Baden and Philips as an industrial partner and is making the tiniest tissue changes visible. This has the potential to improve the early detection of breast cancer. Further studies in women suffering from breast cancer are to prove in a definitive manner the added value of the method.
Helena Van Swygenhoven, materials researcher at the Paul Scherrer Institute and professor at the Swiss Federal Institute of Technology in Lausanne (EPFL), has been awarded an ERC Advanced Grant. This prestigious EUR 2.5 million grant from the European Research Council will enable Van Swygenhoven to launch the new research project MULTIAX. Under this project, she will investigate what happens in metallic materials during deformation - a question important for the production processes for car parts. Furthermore, the project will also develop new methods that can be used to study materials at large research facilities. These methods will be accessible to experts from research and industry.
Mit Hilfe von Röntgenlicht aus der Synchrotron Lichtquelle Schweiz des PSI ist es Paläontologen der Universität Bristol gelungen, ein Rätsel um den Ursprung der ersten Wirbeltiere mit harten Körperteilen zu lösen. Sie haben gezeigt, dass die Zähne altertümlicher Fische (der sogenannten Conodonten) unabhängig von den Zähnen und Kiefern heutiger Wirbeltiere entstanden sind. Die Zähne dieser Wirbeltiere haben sich vielmehr aus einem Panzer entwickelt, der dem Schutz vor den Conodonten, den ersten Raubtieren, diente.
How will the world secure its energy supply in 2050 and what are the possible economic, ecological and social implications of different pathways and choices? These questions are answered by researchers at the Paul Scherrer Institute PSI in cooperation with the World Energy Council WEC in a study examining two scenarios covering different dimensions of economic, social, policy and technology development. The results of the study, which has now been concluded, will be presented from 13 to 17 October at the WEC’s World Energy Congress in the South Korean town of Daegu
Clouds consist of cloud droplets that are formed from tiny particles floating in the atmosphere. How these particles develop, however, largely remains a mystery. The formation of particles from amines and sulphuric acid has now been described for the first time à a milestone in atmospheric research.

A terahertz laser developed at the Paul Scherrer Institute makes it possible to control a material’s magnetisation precisely at a timescale of picoseconds. In their experiment, the researchers shone extremely short light pulses from the laser onto a magnetic material. The light pulse’s magnetic field was able to deflect the magnetic moments from their idle state in such a way that they exactly followed the change of the laser’s magnetic field with only a minor delay. The terahertz laser used in the experiment is one of the strongest of its kind in the world.
Five times less platinum: fuel cells could become economically more attractive thanks to novel aerogel catalyst.
Fuel cells that convert hydrogen into power and only produce pure water as a by-product have the potential to lead individual mobility into an environmentally friendly future. The Paul Scherrer Institute (PSI) has been researching and developing such low-temperature polymer electrolyte fuel cells for more than 10 years and initial field tests have already demonstrated the successful use of these fuel cells in cars and buses. However, further research is still required to improve the durability and economic viability of the technology. An international team of researchers involving the PSI has now manufactured and characterised a novel nanomaterial that could vastly increase the efficiency and shelf-life of these fuel cells à as well as reduce material costs.
Better than CT and MRI: researchers at the Inselspital Berne, the University Hospital Basel and the Paul Scherrer Institute have devised a new method to detect small tumours in the pancreas.
Researchers from the Paul Scherrer Institute (PSI) have made thin, crystalline layers of the material LuMnO3 that are both ferromagnetic and antiferromagnetic at the same time. The LuMnO3 layer is ferromagnetic close to the interface with the carrier crystal. As the distance increases, however, it assumes the material’s normal antiferromagnetic order while the ferromagnetism steadily becomes weaker. The possibility of producing two different magnetic orders within a material could be of major technical importance.
