Transformation in the particle zoo

An international study led by the University of Bonn has found evidence of a long-sought effect in accelerator data. The so-called "triangle singularity" describes how particles can change their identities by exchanging quarks, thereby mimicking a new particle. The mechanism also provides new insights into a mystery that has long puzzled particle physicists: Protons, neutrons and many other particles are much heavier than one would expect. This is due to peculiarities of the strong interaction that holds the quarks together. The triangle singularity could help to better understand these properties. The publication is now available in Physical Review Letters.

Should cancer patients participate in tumour conferences?

The goal of tumour conferences is to determine the best treatment for patients with complex cancers. In these interdisciplinary meetings, doctors from various branches of medicine convene to talk about a patient's case - however, the patient is rarely present. In the PINTU study a team of researchers from the University of Oldenburg and the University Hospitals of Bonn and Cologne has now investigated whether cancer patients can benefit from participating in these meetings. The study, which was funded by Deutsche Krebshilfe e.V., has now been published in the journal "Cancer Medicine".

What factors impact the spread of viruses?

Many different factors are responsible for the spread of infectious diseases. What is known is that the spread process depends essentially on the infectiousness of the pathogen and the immune response of the host, but also on human behavior. This relates, for example, to the extent to which distance regulations are observed. Less often considered, however, is the fact that the factors and their influence can vary greatly between groups of people - both at the biomedical and socioeconomic levels. Mathematicians, physicians and economists now want to take a closer look at this so-called inter-individual variability in a joint collaboration project of the University of Bonn and the University Hospital Munich. The goal is to determine new factors that are relevant for the transmission or containment of SARS-CoV-2 viruses. The German Research Foundation (DFG) is funding the project with several hundred thousand euros, of which 270,000 euros will go to Bonn.

University of Bonn improves in Shanghai ranking

According to the recently published university ranking of the Chinese Jiaotong University in Shanghai, the University of Bonn is among the four best universities in Germany, the best 20 universities in the European Union and among the 100 top universities in the world. Compared to the previous year, Bonn was able to improve by three places to 84th place worldwide.

Genetic program protects neurons from degeneration

Researchers at the University of Bonn have identified a previously unknown genetic program in the fruit fly. The genetic material involved controls the development of the neurons while also protecting them from degeneration. They have hardly changed in the course of evolution over hundreds of millions of years and also exist in a comparable form in humans. Initial data show that they presumably perform similar tasks there. The results may therefore also provide a starting point for new active ingredients for neurodegenerative diseases. They are published in the journal Neuron.

Exciting science in the center of Cologne

Think "outside the box" is often the phrase used to describe leaving your old thinking habits behind and getting creative. This is exactly what scientists from the universities of Cologne, Bonn and Düsseldorf will be doing on August 21, starting at 2 p.m. on Cologne's Rudolfplatz: Standing on a "soap box," they want to inspire the general public with their research topics. They have previously learned in a workshop how to do this without technical aids, PowerPoint presentations or lecture halls. All citizens are invited to learn about exciting science from the world of immunology, aging and plant research in a relaxed atmosphere. The lectures will be held mostly in German and partly in English. Participation is free of charge.

500 million measurements on the impact of climate change

It is the most comprehensive study of its kind to date: Researchers at the University of Bonn and the University of South-Eastern Norway have studied how two characteristic arctic-alpine plant species respond to global warming. They did this by analyzing almost 500 million of their own readings from the mountainous region of Norway. The analyses show that potential consequences of climate change are extremely dependent on the specific location of the plants and that deciduous species in particular will benefit from warming. The result would be a further increase in the trend toward greening of the arctic-alpine regions. The study is published in the journal Ecosphere.

Artificial intelligence to detect brain hemorrhages

Research across disciplinary boundaries: the Institute for Applied Mathematics at the University of Bonn and the Clinic for Neuroradiology at the University Hospital Bonn (UKB) have received funding of around 160,000 euros for a joint project on the automated detection of brain hemorrhages using artificial intelligence. The project is supported by the Hausdorff Center for Mathematics (HCM) Cluster of Excellence at the University of Bonn.
