Since more than a decade it has been possible for physicists to accurately measure the location of individual atoms to a precision of smaller than one thousandth of a millimeter using a special type of microscope. However, this method has so far only provided the x and y coordinates. Information on the vertical position of the atom – i.e., the distance between the atom and the microscope objective – is lacking. A new method has now been developed that can determine all three spatial coordinates of an atom with one single image. This method – developed by the University of Bonn and University of Bristol – is based on an ingenious physical principle. The study was recently published in the specialist journal Physical Review A.

T follicular helper cells (Tfh) are essential for strong antibody-mediated reactions of our immune system during infections and vaccinations. However, if they get out of control, this can cause diseases such as autoimmunity, allergies or cancer. Researchers from the University Hospital Bonn (UKB) and the Cluster of Excellence ImmunoSensation2 at the University of Bonn investigated the underlying mechanisms of Tfh cell development in a mouse model and thus decoded their internal networking. They hope that this will lead to new strategies for the development of highly effective vaccines and new therapies to combat various diseases. The results have now been published in the renowned journal "Science Immunology".

Evidence-based policy advice at its best: the Bioeconomy Advisory Board NRW, with two members from the University of Bonn, began its work yesterday.

When people lack visual imagination, this is known as aphantasia. Researchers from the University Hospital Bonn (UKB), the University of Bonn and the German Center for Neurodegenerative Diseases (DZNE) investigated how the lack of mental imagery affects long-term memory. They were able to show that changes in two important brain regions, the hippocampus and the occipital lobe, as well as their interaction, have an influence on the impaired recall of personal memories in aphantasia. The study results, which advance the understanding of autobiographical memory, have now been published online by the journal "eLife".

The state premier of North Rhine-Westphalia, Hendrik Wüst, visited the Humanoid Robots Lab at the University of Bonn on Thursday afternoon. Talks centered on current research projects in the field of robotics and the challenges associated with the use of robots in human environments. The state premier was able to enter virtual reality with a robot and watch a three-armed robot harvesting peppers.

Researchers at the University Hospitals of Dresden and Bonn of the DFG Transregio 237 and from the Cluster of Excellence ImmunoSensation2 at the University of Bonn have made progress clarifying why patients with myotonic dystrophy 2 have a higher tendency to develop autoimmune diseases. Their goal is to understand the development of the disease, and their research has provided new, potential therapeutic targets. The results of the study have now been published in the renowned journal "Nature Communications".

Researchers from Carnegie Mellon University, the University Hospital Bonn and the University of Bonn have created an open-source platform known as A-SOiD that can learn and predict user-defined behaviors, just from video. The results of the study have now been published in the journal "Nature Methods".

To synthesize potential drugs or natural products, you need natural substances in specific mirror-image variants and with a high degree of purity. For the first time, chemists at the University of Bonn have succeeded in producing all eight possible variants of polypropionate building blocks from a single starting material in a relatively straightforward process. Their work has now been published in the prestigious journal “Angewandte Chemie.”
