News
Early galaxies contribute to the “afterglow” of the universe
The “afterglow” of the universe is an important piece of evidence for the Big Bang. This background radiation also provides important answers to the question of how the first galaxies were able to form. Researchers at the Universities of Bonn, Prague and Nanjing calculate that the strength of this radiation has probably been overestimated up to now. If the results prove to be accurate, it would call into question the theoretical foundation of the standard model of cosmology. The results have now been published in the journal “Nuclear Physics B.”
Bacterium Produces “Organic Dishwashing Liquid” to Degrade Oil
The marine bacterium Alcanivorax borkumensis feeds on oil, multiplying rapidly in the wake of oil spills, and thereby accelerating the elimination of the pollution, in many cases. It does this by producing an “organic dishwashing liquid” which it uses to attach itself to oil droplets. Researchers from the University of Bonn, RWTH Aachen University, Heinrich Heine University Düsseldorf and research center Forschungszentrum Jülich have now discovered the mechanism by which this “organic dishwashing liquid” is synthesized. Published in the prominent international journal Nature Chemical Biology, the research findings could allow the breeding of more efficient strains of oil-degrading bacteria.
An inexhaustible source of profound questions
Finding the best possible solution to complex problems with the help of mathematics, computer science and economics - that is the goal of Professor László Végh, who has been the University of Bonn's new Hertz Chair for Algorithms and Optimization since August 2024. Together with his transdisciplinary team, he develops efficient algorithms and expands our understanding of the limits of computability. The inaugural symposium on 25 April 2025 provided a broad insight into the various research areas - from game theory to the latest developments in the theory of optimization.
Innovative New Detector to Hunt for Neutrinos
Technology is being pushed to its very limits. The upgrades to the Large Hadron Collider (LHC) at CERN slated for the next few years will increase data transfer rates beyond what the current neutrino detector for the FASER experiment can cope with, requiring it to be replaced by a new kind of more powerful detector. This is a task that physicist Professor Matthias Schott from the University of Bonn will be tackling with the help of €1 million in Reinhart Koselleck funding from the German Research Foundation (DFG).
A new approach to extreme events such as epileptic seizures and climate change
The global climate is in an imbalance. Potential "tipping elements " include the Greenland ice sheet, coral reefs, and the Amazon rainforest. Together they form a network that can collapse if just one individual component tips. Researchers from Bonn University Hospital (UKB) and the University of Bonn have now shed light on seemingly sudden and rare, often irreversible changes within a system, such as those that can be observed in the climate, the economy, social networks or even the human brain. They took a closer look at extreme events such as epileptic seizures. Their aim was to better understand the mechanisms underlying such changes in order to ultimately make predictions. The results of their work have now been published in the journal "Physical Review Research".
Immune Cells Drive Congenital Paralysis Disease
Patients with spastic paraplegia type 15 develop movement disorders during adolescence that may ultimately require the use of a wheelchair. In the early stages of this rare hereditary disease the brain appears to play a major role by over-activating the immune system, as shown by a recent study published in the Journal of Experimental Medicine. The study was led by researchers at the University of Bonn and the German Center for Neurodegenerative Diseases (DZNE). These findings could also be relevant for Alzheimer's disease and other neurodegenerative conditions.
New way to prevent duodenal cancer
People with the hereditary disease familial adenomatous polyposis (FAP) have a greatly increased risk of developing a malignant tumor of the duodenum. Researchers at the University Hospital Bonn (UKB) and the Cluster of Excellence ImmunoSensation2 at the University of Bonn have now discovered a mechanism in the local immune system that can drive the development of cancer. They see this as a promising new approach to preventing duodenal carcinoma in people with FAP. The results have now been published in the journal "Nature Communications".
