A speed limit also applies in the quantum world

Even in the world of the smallest particles with their own special rules, things cannot proceed infinitely fast. Physicists at the University of Bonn have now shown what the speed limit is for complex quantum operations. The study also involved scientists from MIT, the universities of Hamburg, Cologne and Padua, and the Jülich Research Center. The results are important for the realization of quantum computers, among other things. They are published in the prestigious journal Physical Review X, and covered by the Physics Magazine of the American Physical Society.

A WLAN Router May Become Your New Security Guard

Can standard wireless computer networks (WLAN) be used to track burglars more effectively? Researchers at the University of Bonn, together with colleagues at the Osnabrück Police Department and the Karlsruhe Institute of Technology (KIT), believe it is possible. Their plan is to use routers to identify unauthorized intruders and trigger an alarm. The project, dubbed “WACHMANN,” will bring roughly 560,000 euros in funding to the University of Bonn as part of the “Research for Civil Security” program by the Federal Ministry of Education and Research (BMBF).

Prolonged anesthesia alters how the brain is wired

Prolonged anesthesia, also known as medically induced coma, is a life-saving procedure carried out across the globe on millions of patients in intensive medical care units every year. But following prolonged anesthesia--which takes the brain to a state of deep unconsciousness beyond short-term anesthesia for surgical procedures--it is common for family members to report that after hospital discharge their loved ones were not quite the same. A study by researchers at Columbia University and the University of Bonn now supports reports of neuro-cognitive changes after medically induced comas, a procedure that has been relied upon in treating COVID-19 patients during the pandemic. The study has been published in the journal PNAS.

Real-time behavioral analysis using artificial intelligence

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 inflammation

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.
