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.
Crystal structure of SARS-CoV-2 Orf9b in complex with human TOM70 suggests unusual virus-host interactions
In a study published in Nature Communications, researchers at the NHC Key Laboratory of Systems Biology of Pathogens in Beijing, China, in collaboration with the Paul Scherrer Institut characterize the interactions of SARS-CoV-2 orf9b and human TOM70 biochemically, and they determine the 2.2 Å crystal structure of the TOM70 cytosolic domain with a bound SARS-CoV-2 orf9b peptide.
Myelin 'insulates' our neurons enabling fast signal transduction in our brain. Myelin levels, integrity, and neuron orientations are important determinants of brain development and disease. Small-angle X-ray scattering tensor tomography (SAXS-TT) is a promising technique for non-destructive, stain-free imaging of brain samples, enabling quantitative studies of myelination and neuron orientations, i.e. of nano-scale properties imaged over centimeter-sized samples.
Forschende der Goethe-Universität Frankfurt haben in Kooperation mit dem PSI vermutlich einen weiteren, bislang unbekannten Wirkmechanismus des Virostatikums Remdesivir entdeckt.
In a study addressing the global health threat of drug resistance, researchers at the Biozentrum, University of Basel, have revealed how a new antibiotic, Darobactin, binds to the external membrane of gram-negative bacteria.
Detailed characterization of the tooth and jaw structure and development among shark ancestors by synchrotron based X-ray tomographic microscopy at TOMCAT led an international team of researchers from the Naturalis Biodiversity Center in Leiden and the University of Bristol to the discovery that while teeth evolved once, complex dentitions have been gained and lost many times in evolutionary history.
The paper "High aspect ratio grating microfabrication by Pt assisted chemical etching and Au electroplating” by Dr. Lucia Romano & coauthors has been highlighted in the "Women in Engineering Materials" Virtual Issue published on Advanced Engineering Materials. This Virtual Issue draws attention to outstanding works within Materials Science created under the lead of women as principal investigators.
Congratulations to Lucia and the x-ray optics design and fabrication team!
During the week of March 15 – 19, we had the pleasure to welcome 20 international PhD students, PostDocs and assistant professors at PSI, taking part in the first virtual HERCULES SCHOOL on Neutrons & Synchrotron Radiation.
