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 – 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.

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.

11. August 2013Media Releases Matter and Material Materials Research SwissFEL
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 catalystMedia Releases Energy and Environment
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 – 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.
12. July 2013Media Releases Matter and Material Materials Research
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.

Scientists use nano-rods to investigate how matter assembles
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. The model: rings made from six nanoscale magnetic rods, whose north and south poles attract each other. 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”.

Lithium-ion batteries are high performance energy storage devices used in many commercial electronic appliances. Certainly, they can store a large amount of energy in a relatively small volume. They have also previously been widely believed to exhibit no memory effect. That’s how experts call a deviation in the working voltage of the battery, caused by incomplete charging or discharging, that can lead to only part of the stored energy being available and an inability to determine the charge level of the battery reliably. Scientists at the Paul Scherrer Institute PSI, together with colleagues from the Toyota Research Laboratories in Japan have now however discovered that a widely-used type of lithium-ion battery has a memory effect. This discovery is of particularly high relevance for advances towards using lithium-ion batteries in the electric vehicle market. The work was published today in the scientific journal Nature Materials.
8. April 2013Media Releases SwissFEL Matter and Material
Prominent among the planned applications of X-ray free electron laser facilities, such as the future SwissFEL at the Paul Scherrer Institute, PSI, are structural studies of complex nano-particles, down to the scale of individual bio-molecules. A major challenge for such investigations is the mathematical reconstruction of the particle form from the measured scattering data. Researchers at PSI have now demonstrated an optimized mathematical procedure for treating such data, which yields a dramatically improved single-particle structural resolution. The procedure was successfully tested at the Swiss Light Source synchrotron at PSI.
3. April 2013Media Releases Matter and Material Research Using Neutrons
Developmental Engineers from the firm LuK (D) wanted to see right through the metal housing of a clutch. They wanted to observe how the oil that lubricates and cools a clutch is distributed. A transparent disc becomes dirty very quickly, and X-rays merely reveal the metal. These engineers therefore turned to scientists at the Paul Scherrer Institute, who illuminated the metal with neutrons and thus made the lubricating oil visible. The results surprised everyone: only three of the eight lamellae were sufficiently lubricated.

14. February 2013Media Releases Biology Human Health
Numerous processes taking place within our body, such as sight, smell or taste, are accomplished by an important family of sensors on cell surfaces, which are known as G protein-coupled receptors (GPCR). Researchers have now compared the hitherto known structures of GPCRs and discovered a stabilising framework of fine struts that is characteristic for the architecture of the entire GPCR family. Knowledge about this constructional feature, which has been conserved over the course of evolution, can be of significant assistance in the development of new pharmaceuticals.

X-rays are used to investigate nanoscale structures of objects as varied as single cells or magnetic storage media. Yet, high-resolution images impose extreme constraints on both the X ray microscope and the samples under investigation. Researchers at the Technische Universität München the PSI now showed how to relax these conditions without loss of image quality. They further showed how to image objects featuring fast fluctuations, such as the rapid switching events that determine the life time of data storage in magnetic materials.
