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.
A particular variety of particles, the so-called Weyl fermions, had previously only been detected in certain non-magnetic materials. But now researchers at PSI have experimentally proved their existence for the first time in a specific paramagnetic material.
Using the Swiss Light Source SLS, PSI researchers have recorded a molecular energy machine in action and thus revealed how energy production at cell membranes works. For this purpose, they developed a new investigative method that could make the analysis of cellular processes significantly more effective than before.
Researchers at the Paul Scherrer Institute PSI analyse the potential of Power-to-X for Switzerland's energy supply and present their conclusions in a white paper. One finding: The costs for energy from Power-to-X could fall by up to one-third.
Researchers at the Paul Scherrer Institute PSI have an important part of the regulatory cycle that is involved in the formation and degradation of the cytoskeleton. Among other things, they have watched molecular scissors at work.
PSI researchers are helping the European space program: Their neutron imaging serves to ensure the quality of critical components for rocket launches.
PSI researchers have developed a material whose shape memory is activated through magnetism. Application areas for this new kind of composite material include, for example, medicine, space flight, electronics, and robotics.
Researchers at PSI have investigated a novel crystalline material at the Swiss Light Source SLS that exhibits electronic properties never seen before. Among other things, they were able to detect a new type of quasiparticle: so-called Rarita-Schwinger fermions.
Researchers at the Paul Scherrer Institute PSI have elucidated an important part of a siganalling pathway that transmits information through the cell membrane into the interior of a cell. This exists in all mammals and plays an important role, among other things, in the regulation of the heartbeat. The new findings could lead to new therapies.
Researchers at PSI have discovered a new phenomenon of magnetism with the help of the Swiss Light Source SLS. Certain groups of atoms behave like a compass pointing West. This could make computers much more powerful.
At PSI, Beate Timmermann built up a programme providing proton therapy for children with cancer at the same time she was raising her own son. Today she is head of the Clinic for Particle Therapy at the West German Proton Therapy Centre in Essen (WPE) and is considered one of the most accomplished experts in this field.
A method developed by PSI researchers makes X-ray images of materials even better. The researchers took a number of individual images while moving an optical lens. From these, with the help of computer algorithms, they generated one overall image.
A PSI-developed detector called POLAR has collected data on so-called gamma-ray bursts from a space station. This is now helping to better understand these extremely high-energy flashes of light.
A team with three researchers from the ETH Domain has been awarded a prestigious EU grant. Today, they received the contract signed by the EU confirming the extraordinary 14 million euros funding. With it, they will investigate quantum effects which could become the backbone of future electronics.
Use of multiferroic materials promises more energy-efficient computers because in these, an electric field would suffice to achieve magnetic data storage. Researchers at PSI have now made such a material suitable for computer operating temperatures.
In the first half of the 19th century, a series of large volcanic eruptions in the tropics led to a temporary global cooling of Earth's climate. That Alpine glaciers grew and subsequently receded again during the final phase of the so-called Little Ice Age was due to a natural process. This has now been proven by PSI researchers on the basis of ice cores.
For the development of new medicinal agents, accurate knowledge of proteins is crucial. In a pilot experiment, researchers have now, for the first time, used the X-ray free-electron laser SwissFEL of PSI for the examination of protein crystals.
Shortly after the Big Bang, radioactive Beryllium-7 atoms were formed, which today, throughout the universe, they have long since decayed. A sample of beryllium-7 artificially produced at PSI has now helped researchers to better understand the first minutes of the universe.
The electronics industry expects a novel high-performance transistor made of gallium nitride to offer considerable advantages over present-day high-frequency transistors. Yet many fundamental properties of the material remain unknown. Now, for the first time, researchers at the Paul Scherrer Institute PSI have observed electrons while they were flowing in this promising transistor. For that they used one of the world's best sources of soft X-rays at PSI's Swiss Light Source SLS.
