Inflammatory reactions in the skin can reduce damage from UV radiation or infections, but can also result in painful symptoms such as sunburn. A recent study at the University of Bonn and the University Hospital Bonn has now identified a molecular control which integrates these stress signals. The results have been published in the Journal of Experimental Medicine.

The prestigious US News & World Report rankings which assesses a range of subject areas, reached a favorable verdict on the University of Bonn. The University’s performance in six of the subjects considered was assessed as ranking amongst the top five universities in Germany, whilst it made the top ten in 14 other areas. The subjects mathematics, economics and nutrition and food sciences were especially successful.

UV light makes it possible to see intricate structures of fossils that are barely visible in normal daylight. This method has often been used on the fossilised seashells from the Earth’s current geological era to reveal patterns of colour that had long since faded away. Now, research by a scientist from the University of Göttingen shows that fluorescent colour patterns can even be found in shells that are around 240 million years old, from the Earth's Mesozoic Era. This makes them the oldest fluorescent colour patterns found so far. The results have been published in the journal Palaeontology. 

Several days ago, a member of our University and of the Faculty of Law and Economics has been accused of severe misconduct in social media. Currently, we have no hard evidence concerning the accusations. The facts are currently being examined.

An international team of astrophysicists has made a puzzling discovery while analyzing certain star clusters. The University of Bonn played a major role in the study. The finding challenges Newton's laws of gravity, the researchers write in their publication. Instead, the observations are consistent with the predictions of an alternative theory of gravity. However, this is controversial among experts. The results have now been published in the Monthly Notices of the Royal Astronomical Society.

Hemophilia A is the most common severe form of hemophilia. It affects almost exclusively males. The disease can usually be treated well, but not for all sufferers. A study at the University of Bonn has now elucidated an important mechanism that is crucial for making the therapy effective. The results could help better tailor treatment to patients. They have already been published online in a preliminary version; the final version will soon be published in the "Journal of Clinical Investigation."

The University of Bonn started the academic year 2022/2023 with a ceremony in the packed main auditorium of the University Main Building.

Distinguished early-career researchers have received state awards as part of the International Days events at the University of Bonn. Sponsored by the governments of Spain, France and the UK, the awards include the Queen’s Prize, created by Queen Elizabeth II (recently deceased) on the occasion of her 1965 visit to the University of Bonn, which recognizes outstanding achievement in English studies. The state awards have traditionally been presented simultaneously with the DAAD Prize of the German Academic Exchange Service for noteworthy accomplishments benefiting society and/or university life.
