An enzyme could make a dream come true for the energy industry: It can efficiently produce hydrogen using electricity and can also generate electricity from hydrogen. The enzyme is protected by embedding it in a polymer. An international research team with significant participation of scientists from Technical University of Munich (TUM) has presented the system in the renowned science journal

Vaccination effective in spite of immune disease
Rheumatism, inflammatory bowel disease and psoriasis are examples of diseases which trigger a false, excessive immune reaction and which require treatment with anti-inflammatory drugs. Researchers from the German Centre for Immunotherapy (DZI; spokespersons: Prof. Dr. Markus F. Neurath and Prof. Dr. med.univ. Georg Schett) at Universitätsklinikum Erlangen, have investigated how well these patients respond to a coronavirus vaccine. Their study is one of the first in the world to explore this topic and provide results. The study has now been published in the journal ‘Annals of the Rheumatic Diseases’.

FRANKFURT. When the SARS-CoV-2 virus mutates, this initially only means that there is a change in its genetic blueprint. The mutation may lead, for example, to an amino acid being exchanged at a particular site in a viral protein. In order to quickly assess the effect of this change, a three-dimensional image of the viral protein is extremely helpful. This is because it shows whether the switch in amino acid has consequences for the function of the protein - or for the interaction with a potential drug or antibody.

BEER-SHEVA, Israel May 10, 2021 - Researchers from Ben-Gurion University (BGU), together with American and German colleagues, have developed new molecular tweezers to combat antibiotic-resistant bacteria. Their recently announced findings were published in
Cell Chemical Biology.
For years, medical professionals have struggled with bacterial infections becoming increasingly resistant to antibiotics. These molecular tweezers may be the key to battling one of greatest public health issues of the 21st century. Our discovery prevents infection without building up antibiotic resistance, and it might even be preferable to develop treatments based on molecular tweezers rather than antibiotics, said BGU Department of Chemistry Prof. Raz Jelinek.

New Research Training Group at Institute of Physics
The German Research Foundation (DFG) has approved new research training groups (GRK) with the goal of supporting young scientists. The funding will go specifically toward establishing the Research Training Group “Dynamics of Controlled Atomic and Molecular Systems (DynCAM)” at the Institute of Physics, University of Freiburg. The DFG will provide six million euros over four-and-one-half years toward the effort. Starting in January 2022, 14 doctoral researchers will be able to study matter at the quantum level in Freiburg and as part of an exchange program in Vancouver, Canada.
Precisely controlled atomic and molecular samples, isolated for example in molecular beams, cluster beams, or special traps, play a key role in this research area, which focuses on understanding the dynamics of underlying processes. The new GRK at the University of Freiburg, in collaboration with the University of British Columbia (UBC) in Va
