The mystery of intermediate-mass black holes
Galaxies contain black holes weighing between approximately five and 100 solar masses. There are also some with more than 100,000 solar masses. But do medium-mass black holes also develop in galaxies? A study by the Astronomical Institute of Charles University in Czechia, with significant participation from the University of Bonn, shows how medium-mass black holes can frequently form naturally. However, this currently only occurs in the innermost regions of star-forming galaxies similar to our Milky Way. The results have now been published in a “Letter to the Editor” in the journal “Astronomy & Astrophysics.” 
When Membranes Become Complex: New Mathematical Insights
Cell membranes, such as those found in red blood cells, naturally adopt optimal geometric shapes that maintain low bending energy. In his newly established Emmy Noether Group, Dr. Christian Scharrer at the Institute of Applied Mathematics at the University of Bonn is exploring the geometric phenomena that arise as membrane shapes become increasingly complex. The German Research Foundation (DFG) has approved €850,000 in funding for the group over a period of up to six years.
Advances in Technology Unlocking More Sustainable Agricultural Systems
The agriculture industry may be producing more food than ever before, but it is also damaging the climate, harming the soil and eroding biodiversity. A team of researchers from the PhenoRob Cluster of Excellence at the University of Bonn has now published a paper in the journal “Agricultural Systems” that explains the key role technological innovations will need to play to make agriculture sustainable in the future and why these will have to be accompanied by shrewd policies and new business models.
Litter in the Rhine River: Some 53,000 Items of Litter Flow Past Cologne Daily
The amount of litter floating in the Rhine is many times larger than previously believed. Researchers from the University of Bonn, the University of Tübingen and the Federal Institute of Hydrology (BfG) partnered with the Cologne-based non-profit pollution-fighting organization K.R.A.K.E. to collect and classify macro litter in a floating litter trap—the only one of its kind in Germany—over a period of 16 months. Extrapolation models based on the observed volume indicate that roughly 53,000 items of macro waste debris float past Cologne on the Rhine river every day. Disposable plastic products make up a large proportion of the litter found in the Rhine. The findings have now been published in the scientific journal “Communications Sustainability.”
