PSI

Researchers at the Paul Scherrer Institute PSI and the Italian Institute of Technology IIT have developed a novel substance that disables a protein in the cell skeleton, leading to cell death. In this way, substances of this type can prevent, for example, the growth of tumours. To accomplish this, the researchers combined a structural biological method with the computational design of active agents.

Researchers at PSI have observed for the first time how tiny magnets in a special layout align themselves solely as a result of temperature changes. This view into processes that take place within so-called artificial spin ice could play an important role in the development of novel high-performance computers. The results were published in the journal Nature Physics.

Glacier ice holds valuable information about our planet’s past. But as the glaciers melt in the course of climate change, this archive is disappearing. An international research team with PSI participation is rushing to preserve this scientific treasure for posterity.

Cryo-electron microscopy is still a comparatively new method for elucidating the three-dimensional structure of biomolecules. It can help researchers resolve many open questions about light-sensitive proteins, rapidly and with high precision.

PSI scientists have developed a ground-breaking achromatic lens for X-rays. This allows the X-ray beams to be accurately focused on a single point even if they have different wavelengths. The new lens will make it much easier to study nanostructures using X-rays, according to a paper just published by the researchers in the scientific journal Nature Communications.
