Röntgenmikroskopie mit 1000 Tomogrammen pro Sekunde
An der Synchrotron Lichtquelle Schweiz SLS haben Forschende einen neuen Rekord in einer Bildgebungsmethode namens Tomoskopie aufgestellt.
Das Rätsel der biegsamen Schale
Weshalb die Hülle eines Meerestiers im Wasser weich, an der Luft aber hart ist.
Hierarchical imaging and computational analysis of three-dimensional vascular network architecture in mouse brain
An international team involving researchers from the University and University Hospital Zürich, the Krembil Research Institute and the University and University Hospital in Toronto (Canada), the Department of Physics of Jyväskylä (Finland), the University of Leuven (Belgium), the Johannes Kepler University in Linz (Austria), the Novartis Institutes for Biomedical Research in Emeryville (USA), the ETH Zürich and the Paul Scherrer Institute has developed a protocol that enables hierarchical imaging and computational analysis of vascular networks in entire postnatal- and adult mouse brains, enabling direct and quantitative comparisons of the morphological brain vascular network architecture between different postnatal and / or adult developmental stages. The results have been published on Nature Protocols on September 3rd, 2021.
Nanobodies against SARS-CoV-2
In a study published in EMBO Journal, researchers at the Max Planck Institute for Biophysical Chemistry, Göttingen, Germany, developed nanobodies that efficiently block the coronavirus SARS-CoV-2 and its variants. The high resolution structural characterization was performed at the X10SA crystallography beamline at the Swiss Light Source.
Imaging strain with high resolution
Imaging strain in crystalline materials with high resolution can be a challenging task. Researchers demonstrate an original use of X-ray ptychography for this purpose: ptychographic topography.
How ethane-consuming archaea pick up their favorite dish
Scientists decode the structure of the enzyme responsible for the ethane fixation by – beside others – using the SLS.
PSI: stetig voran im Kampf gegen Corona
Kristallstrukturanalyse, Computermodelle, Zellkulturen – um Sars-CoV-2 zu erforschen, beschreitet das PSI viele Wege. Ein Überblick.
Stoneflies: Youth influences adulthood
Evolutionary biologists at the University of Bonn scan 219 species in different particle accelerators, beside others the Swiss Light Source SLS.
Wie Katalysatoren altern
Katalysatoren, die in der Industrie eingesetzt werden, verändern über die Jahre ihre Materialstruktur. Mit einer neuen Methode haben PSI-Forschende dies nun auf der Nano-Skala untersucht.
