Calcium sensor helps us to see the stars
New insight into how the protein calmodulin interacts with an ion channel in the eye could explain how our eyes achieve remarkable sensitivity to dim light.
How vision begins
PSI scientists have discovered the very first step occurring in the eye when light hits the retina.
Using light to switch drugs on and off
PSI researchers record a molecular film of a cancer drug fitted with a photoswitch. This opens new insights for drug developers.
A new spin on sample delivery for membrane proteins
Proteins hover in front of the X-ray beam at a Swiss Light Source beamline. Now, spinning thin films bring on board these trickiest of proteins.
How to get chloride ions into the cell
A molecular movie shot at PSI reveals the mechanism of a light-driven chloride pump
New, better coronavirus rapid test
The test identifies different virus variants and improves disease prognosis.
Cell cytoskeleton as target for new active agents
Using a combination of computer simulations and laboratory experiments, PSI researchers have identified new binding sites for active agents on the vital protein tubulin.
PSI Thesis Medal 2021 for pioneering Structural Biology at SwissFEL
Dr. Petr Skopintsev received PSI Thesis Medal 2021 for his work on the sodium pump KR2.
Elucidating the mechanism of a light-driven sodium pump
Researchers at the Paul Scherrer Institute PSI have succeeded for the first time in recording a light-driven sodium pump from bacterial cells in action. The findings promise progress in developing new methods in neurobiology. The researchers used the new X-ray free-electron laser SwissFEL for their investigations.
