Elevator helps bacteria to build an invisibility cloak

The transport of substances across the membrane into the cell is linked to specific membrane transport proteins. Researchers at the University Hospital Bonn (UKB) and the University of Bonn, in collaboration with an international team, have now succeeded in elucidating the molecular structure of a completely new class of such membrane transporters. In addition to the Bonn scientists, researchers from the University of York were also involved. The study has now been published in the journal Nature Communications.

Comparison of two nano rulers

In the Middle Ages, every city had its own system of measurement. Even today, you can sometimes find iron rods in marketplaces that determined the length measurement valid for the city at that time. In science, however, there is no room for such uncertainties, and no matter what method you use to measure the length of a molecule, for example, the answer should always be the same. Researchers at the University Hospital Bonn (UKB), the University of Bonn and Ludwig-Maximilians-Universität (LMU) Munich have now investigated whether this is true for two methods that are very often used to measure distances in protein molecules - for example, to find out how such molecules move. The study has now appeared in the journal Nature Communications.

Exciting science in the city center of Bonn

Not in a lecture hall, but in the middle of Bonn's city center, twelve young researchers from the universities of Bonn, Cologne and Düsseldorf will give insights into their daily research work and answer questions on August 6 from 1 to 4 p.m. on Bottlerplatz. Inspired by the "Speakers Corner" in London's Hyde Park, where debates and discussions were held in public and with the participation of the audience, the scientists will stand on wooden boxes (soapboxes) and present their research in an understandable and descriptive way - partly in German, partly in English.

Covid-19: New energy for flagging immune cells

In severe Covid-19 patients, the metabolism produces insufficient amounts of certain energy-rich compounds called ketone bodies. However, these energy carriers are needed by two important cell types in the immune system in order to fight the virus effectively. Perhaps this finding explains why some people fall ill so much more severely than others. A study led by the University of Bonn and the University Hospital Bonn at least points in this direction. The results have now been published in the journal Nature. They also give hope for new therapies.

Ten million euros for archaeologists at the University of Bonn

The four Roman legionary fortresses in Bonn, Neuss, Xanten and Nijmegen still hold unexplored treasures of knowledge about the multifaceted life of the Romans on the Lower Rhine. The goal of a team led by archaeologist Prof. Dr. Jan Bemmann from the University of Bonn is to decipher these and preserve them for future generations of researchers. The project is now receiving major support from the Academies Programme, which is jointly funded by the federal and state governments: As one of five newly funded long-term projects, it will receive around ten million euros for the next 18 years.

Four ERC Grants for the University of Bonn

Good news for the University of Bonn: Four scientists receive a coveted grant from the European Research Council (ERC) and thus funding in the millions for the next five years. Prof. Dr. Valentin Blomer from the Institute of Mathematics receives a so-called Advanced Grant, Prof. Dr. Claude Duhr from the Institute of Physics a Consolidator Grant, Dr. Julian Schmitt from the Institute of Applied Physics and Prof. Dr. Georg Oberdieck from the Institute of Mathematics each a Starting Grant.
