Real-time behavioral analysis using artificial intelligence¹

Every behavior of an animal is based on the interaction of many nerve cells in the brain, which form a close-meshed web called a neuronal network. However, what happens in the neuronal networks during particular behaviors is not easy for researchers to study - they have to describe the sequences of recurring postures and link them directly to the neuronal processes. Researchers at the University of Bonn have now presented a new method that is expected to improve this. DeepLabStream is the name of the system that uses artificial intelligence to estimate the posture and behavioral expressions of mice in real time and can respond to them immediately. Light beams are used to label and even influence specific neuronal populations in the brain in order to determine the causality between the neuronal networks and the observed behavior. The study has been published in the journal "Communications Biology".

Study in Tanzania: a traditional diet causes less inflammation³

Urban Tanzanians have a more activated immune system compared to their rural counterparts. The difference in diet appears to explain this difference: in the cities, people eat a more western style diet, while in rural areas a traditional diet is more common. A team of researchers from Radboud university medical center (Netherlands), the LIMES Institute at the University of Bonn, the German Center for Neurodegenerative Diseases (DZNE) and the Kilimanjaro Clinic Research Center in Tanzania presents in a recent study that this increased activity of the immune system could contribute to the rapid increase in non-communicable diseases in urban areas in Africa. The study has been published in the scientific journal Nature Immunology.

Neurons: "String of lights" indicates excitation propagation⁶

A type of novel molecular voltage sensor makes it possible to watch nerve cells at work. The principle of the method has been known for some time. However, researchers at the University of Bonn and the University of California in Los Angeles have now succeeded in significantly improving it. It allows the propagation of electrical signals in living nerve cells to be observed with high temporal and spatial resolution. This enables investigations into completely new questions that were previously closed to research. The study has now been published in the journal PNAS.

Exceptions for On-Site Examinations and Courses⁷

The first examination period of the winter semester traditionally starts in early February. This year, however, the pandemic is turning the usual routines upside down. While on-site examinations are the standard for times when there is no coronavirus, almost everything is taking place digitally this semester. Exceptions may apply, however, under certain circumstances.

Prestigious award for developmental biologist Elvira Mass⁸

The course for organ health is set in the early embryo. For this finding, Prof. Elvira Mass, a scientist at the University of Bonn, receives the Paul Ehrlich and Ludwig Darmstaedter Prize for Young Researchers, which is endowed with 60,000 euros. In her research, she showed that specialized immune cells from the yolk sac accompany organ development and contribute to maintaining their health throughout life. For Elvira Mass, impaired function of these immune cells might cause many diseases.
