Ursa Major III, the faintest object in our galaxy, orbits the Milky Way at a distance of more than 30,000 light years. Until now, it was considered a dwarf galaxy, thought to consist mainly of dark matter due to its large mass. However, an international team of astrophysicists from the University of Bonn and the Institute for Advanced Studies in Basic Sciences in Iran has found evidence suggesting that it is actually a compact star cluster containing a black hole core. The study has been published in the Astrophysical Journal Letters.

The recently published Shanghai Academic Ranking of World Universities (ARWU) still puts the University of Bonn among the four best universities in Germany. It has been placed 11th in the list of top universities in the EU and 68th in the world.

A research team from the University Hospital Bonn (UKB), the University of Bonn, and the Medical Center – University of Freiburg has gained new insights into the brain processes involved in encoding and retrieving new memory content. The study is based on measurements of individual nerve cells in people with epilepsy and shows how they follow an internal rhythm. The work has now been published in the journal Nature Communications.

A series of workshops were held at the University of Bonn on developing ideas and proposals promoting sustainability in higher education. At the sessions, teaching staff, students and outside experts discussed potential new ways to empower students to make society more sustainable, thereby driving forward transformation at the University of Bonn.

To positively influence purchase decisions, sustainability labels must convey a clear signal rather than remain abstract. Using the EU’s “Green Leaf” organic logo as an example, researchers from the universities of Bonn, Newcastle (UK) and Corvinus (Hungary) demonstrate that simple design tweaks reduce consumers’ uncertainty, bolster their trust in the products, and thus increase their willingness to buy. The two‑study-paper appears in the journal "Agribusiness" and is already available online.

With the support of the Ministry of Economic Affairs of the state of North Rhine-Westphalia, a joint consortium of scientific teams and space industry has now launched the “DIEGOSat” satellite feasibility project. Under the leadership of Dr. Johannes Schultz from Ruhr University Bochum, a thermal infrared sensor, originally developed for the International Space Station (ISS), is foreseen to be operated on its own satellite. The satellite sensor will provide thermal imaging data with high temporal resolution, enabling a variety of applications in environmental monitoring, agriculture and disaster control. Researchers from the University of Bonn are involved in the project. 

Artificial intelligence (AI) is designed to make our health system even more efficient. Yet cyberattacks are capable not only of jeopardizing patient safety but also impairing medical devices and hindering the work of emergency responders. With the “SecureNeuroAI” project, researchers from the University of Bonn, University Hospital Bonn and FIZ Karlsruhe – the Leibniz Institute for Information Infrastructure are aiming to develop secure, AI-powered methods for detecting medical emergencies in real time using the example of epileptic seizures, although their findings should be applicable to many other areas. The Federal Ministry of Research, Technology and Space (BMFTR) is providing almost €2.5 million in funding over a three-year period.

A current study by the German Familial Colorectal Cancer Consortium is looking at the question of which people with Lynch syndrome are at an increased risk of developing a second colorectal cancer. Researchers from the University Hospital Bonn (UKB), the University of Bonn and the University of Leipzig have now published their findings in the journal "Clinical Gastroenterology and Hepatology".
