Emerging use of Global Navigation Satellite System (GNSS) makes it possible to continuously measure shallow changes in elevation of Earth surface. A study by the University of Bonn now shows that the quality of these measurements may have improved significantly during the pandemic, at least at some stations. The results show which factors should be considered in the future when installing GPS antennas. More precise geodetic data are important for assessing flood risks and for improving earthquake early warning systems. The journal "Geophysical Research Letters" now reports on this.
How do asymmetrical dependencies and slavery manifest in language, narratives and lexical fields? Scholars of the Cluster of Excellence "Beyond Slavery and Freedom", located at the Bonn Center for Dependency and Slavery Studies at the University of Bonn, worked intensively on this question in their first thematic year, which will culminate with a discussion of their research on October 1 and 2, 2020 at the annual international conference of the Cluster of Excellence. Due to the corona pandemic, the papers will be delivered digitally.
The University of Bonn offers University members with childcare responsibilities financial aid and relief during the coronavirus pandemic through means such as employing assistant personnel.
The University of Bonn will host a high-profile conference with international participation at the beginning of October that will reflect on the motivation behind efforts to internationalize universities. Experts from all over the world will discuss the opportunities and challenges of global networking.
For the brain to work efficiently, nerve impulses must reach their destination as quickly and precisely as possible. The nerve fibres, also known as axons, pass on the impulses, and an insulating sheath around the axons increases their speed of conduction in vertebrates. This insulating sheath, called myelin, is formed by a major component of the brain – the glial cells. Researchers at the University of Münster, in collaboration with colleagues at the University of Bonn, have now discovered that glial cells not only influence the speed of nerve conduction, but also the precision of signal transduction. In the absence of these insulating sheaths, short-circuit-like processes occur. The study has been published in the journal “Nature Communications”.
In the Collaborative Research Centre (CRC) 1211 "Earth - Evolution at the Dry Limit", the mutual relationships between landscape development and the evolution of life are being investigated. The German Research Foundation has extended the CRC and will fund it with approximately eleven million euros over the next four years.
Panthasaurus maleriensis lived about 225 million years ago in what is now India. It is an ancestor of today's amphibians and has been considered the most puzzling representative of the Metoposauridae. Paleontologists from the universities of Bonn and Opole (Poland) examined the fossil's bone tissue and compared it with other representatives of the family also dating from the Triassic. They discovered phases of slower and faster growth in the bone, which apparently depended on the climate. The results have now been published in the journal "PeerJ".
The hemoglobin in the red blood cells ensures that our body cells receive sufficient oxygen. When the blood pigment is broken down, "heme" is produced, which in turn can influence the protein cocktail in the blood. Researchers at the University of Bonn have now discovered in complex detective work that the "activated protein C" (APC) can be commandeered by heme. At the same time, APC can also reduce the toxic effect of heme. Perspectively, the findings may provide the basis for better diagnostic and therapeutic approaches to blood diseases. The study has been published online in advance in the journal "Antioxidants & Redox Signaling". The print version will be published soon.
