Probing what sets the heart racing
New insights into the workings of important drug receptorsMany medical drugs operate on specific receptors located in the outer walls of our body’s cells. One of these is called the beta-1 adrenergic receptor. Among other things, it is responsible for palpitation, the racing pulse that we feel with stage fright or infatuation. How it transmits signals to the cellular interior can now be revealed in detail. These findings could help scientists better understand many drugs' mode of action.
Slowed down current could point the way to energy-saving computers
Computers and other electronic devices account for a substantial portion of worldwide energy use. With today’s technologies, it is not possible to reduce this energy consumption significantly any further; chips in the energy-saving electronics of the future will hence have to be made from novel materials. Researchers at the Paul Scherrer Institute PSI have now found important clues in the search for such materials.
Reappointment of the Directors of PSI and WSL
On application of the ETH Board, the Federal Council reappointed the Director of the Paul Scherrer Institute PSI, Joël Mesot, and the Director of the Swiss Federal Institute for Forest, Snow and Landscape Research WSL, Konrad Steffen, for another four years on 20 January 2016. Joël Mesot’s third term of office will start on 1 August 2016, Konrad Steffen’s second term of office on 1 July 2016.
Neutrons reveal distribution of flux-tube islands
Usually, superconductors expel magnetic fields. In type II superconductors, however, thin channels – so-called flux tubes – are formed. The magnetic field is guided through these tubes while the rest of the material remains field-free and superconducting. In the metal niobium, the flux tubes bunch together into small islands that create complex patterns similar to those found in other fields of nature. A team of researchers from PSI and TU München were the first to conduct neutron experiments to study these patterns in niobium and determine the distribution of the islands in detail.
