Molecular structure of one of the most important receptors in the immune system unraveled
Researchers from Freiburg and Harvard publish the three-dimensional structure of the B cell antigen receptor, shedding new light on its composition The surface of B cells is covered with antigen receptors with which they recognize invading pathogens such as bacteria and viruses. When a B cell receptor binds to an antigen, that is, to a foreign structure, the B cell is activated and triggers the production of antibodies.

Exposure to accents helps children learn words
University of Freiburg study on vocabulary acquisition uses novel game-based design Freiburg, Sep 29, 2022 If elementary school children are accustomed to many regional and foreign accents because they hear them frequently in their linguistic environment, then it is easier for them to learn new words from other children who speak with unfamiliar accents.

Mirror molecules reveal drought stress in forests
Mirror molecules reveal drought stress in forests
Changes in ecosystems can be predicted more accurately via emissions of chiral compounds Worldwide, plants release about 100 million tonnes of monoterpenes into the atmosphere. These volatile organic molecules include many fragrances such as the molecule pinene, known for its fresh pine scent. Since these molecules are very reactive and can form tiny aerosol particles that can grow into condensation nuclei for raindrops, natural emissions play an important role in our climate.

New Software Platform Advances Understanding of the Surface Finish of Manufactured Components
New Software Platform Advances Understanding of the Surface Finish of Manufactured Components
Scientists develop platform that combines measurements of surface topography in a digital twin Scientists from the University of Freiburg, Germany, and the University of Pittsburgh have developed a software platform that facilitates and standardizes the analysis of surfaces. The platform enables users to create a digital twin of a surface and thus to help predict, for example, how quickly it wears out, how well it conducts heat, or how well it adheres to other materials.

New Oxidation State of Rhodium
Previously unknown oxidation state of rhodium(VII) could play a role in chemical reactions Mayara da Silva Santos , doctoral candidate at the University of Freiburg's Institute of Physics, has discovered a new oxidation state of rhodium. This chemical element is one of the most catalytically important platinum-group metals and is used, for example, in catalytic converters for automobiles.

Using nanopores to detect epigenetic changes faster
Using nanopores to detect epigenetic changes faster
A step towards optimizing medical diagnostics Changes known as epigenetic modifications play an important role in cancer development, among other things. Being able to analyze them quickly and reliably could, for example, contribute significantly to the further development of personalized therapy. A research team from the Institute of Physiology at the University of Freiburg has now succeeded in characterizing the chemical changes in proteins that are typical for epigenetic modifications using nanopore analysis.

Connection between a ’calm mind’ and better capacity for self-control
People's self-control can be seen in the stability of their neuronal processes People who have a "calmer mind" - that is, their neuronal processes take longer on average and whirl around less than others - have greater self-control. This was the finding of Dr. Tobias Kleinert, Markus Heinrichs and Dr. Bastian Schiller from the Department of Psychology at the University of Freiburg, together with Kyle Nash and Dr. Josh Leota from the University of Alberta/Canada, and Thomas König from the University Hospital of Bern/Switzerland.

New study on expectations and reality of safe overtaking maneuvers in bicycle traffic
Subjective impressions of safety differs according to the type of road and speed limit Dangerous situations can develop when cyclists are overtaken by cars. How threatened or safe cyclists feel during an overtaking maneuver depends on the type of road. They expect to be safer on roads with a speed limit of 30 kilometers per hour (kph), as well as on living streets, bike streets, and roads with cycle lanes.

Molecular Feedback-Loop for Plant Growth
Molecular Feedback-Loop for Plant Growth
Scientists discover previously unknown mechanism that regulates the growth hormone auxin Plant growth is not a uniform process: Plants grow in length at the shoot and root tip in particular, while in other places they form new leaves or flowers. These different processes must be coordinated with each another and at the same time react to external influences such as temperature and light.
