News from the smog chamber: mechanisms of particle formation in the atmosphere unveiled
Up to the present time, the nucleation or new formation of particles in the atmosphere has been a great enigma. Until recently, research was based on the assumption that sulphuric acid played the central role in particle formation. However, laboratory experiments and field tests have consistently provided conflicting results. In the lab, considerably higher concentrations of sulphuric acid are required for nucleation to take place than in the atmosphere itself. Now scientists from the Paul Scherrer Institute (PSI) have found out the cause for these conflicting results from their smog chamber. These findings will advance climate research to a significant degree.
Attacking the lifeline of tumour cells
Researchers at Biomedicum Helsinki, Finland, and the Paul Scherrer Institute (PSI) in Villigen, Switzerland, have determined the crystal structure of the ligand-binding domain of a vascular endothelial growth factor (VEGF) receptor in complex with one of its ligands (VEGF-C).
Das PSI füllt ein Vakuum mit einem Vakuum
Einweihung Vakuumlabor im Schülerlabor iLab am Paul Scherrer InstitutIm Beisein der Erziehungsdirektoren der Nordwestschweiz hat das Paul Scherrer Institut heute ein zweites Experimentierthema in seinem Schülerlabor iLab eingeweiht. Das neue Vakuumlabor bietet den Schülerinnen und Schülern weitere spannende Versuche und ergänzt das im April 2008 eröffnete Schalllabor in idealer Weise.This news release is only available in German.
