Researchers at the PSI, the EPFL and the Chinese Academy of Science, have proven that the material SmB6 shows all the properties of a so called topological insulator – a material with electric currents flowing along its surface with all of them being polarized. Here, the property is very robust, i.e. the only current that can flow is spin polarized and is not easily destroyed by small irregularities in the structure or composition of the material. Spin polarized currents are necessary for spintronics, electronics using the electrons’ spin.

To make the magnetic interactions between the atoms visible, scientists at the Paul Scherrer Institute PSI have developed a special model system. It is so big that it can be easily observed under an X-ray microscope, and mimics the tiniest movements in Nature.

At room temperature, the magnetisation direction of each of these tiny rods varies spontaneously. Scientists were able to observe the magnetic interactions between these active rods in real time. These research results were published on May 5 in the journal “Nature Physics”.

Like a shredder, the immunoproteasome cuts down proteins into peptides that are subsequently presented on the cellular surface. The immune system can distinguish between self and non-self peptides and selectively kills cells that present non-self peptides at their surface. In autoimmune diseases, this mechanism is deregulated. However, inhibition of the immunoproteasome may alleviate disease symptoms and progression. With the help of measurements taken at the Paul Scherer Institute, scientists have now succeeded in determining the first structure of an immunoproteasome.

The synchrotron light in the SLS is emitted from electrons, which move at a velocity of almost the speed of light along a circular path with an overall circumference of 288 metres. The synchrotron light is emitted tangentially to the trajectory of the electrons, i.e. in the same direction as sparks would fly from a grindstone, or a hammer from the hands of a hammer thrower.
The production of synchrotron radiation makes use of the fact that electrically charged particles emit light as they move along a curved path. Bending magnets keep the electrons on their curved track, as a magnetic field deflects fast-moving electrically-charged particles.
