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.”

The human brain must be able to link memory content to the circumstances in which it occurs. Researchers in Bonn have now discovered how the human brain uses two different groups of neurons to store content and context separately. These nerve cell groups work together in a coordinated manner to form memories, rather than mixing signals in the activity of individual cells. The study results have now been published in the renowned journal Nature.

A new Heisenberg Professor has begun her work at the University of Bonn. Professor Laury Sarti, a medieval historian, is investigating the everyday mobility of people in the Middle Ages, considering not only the nobility but also ordinary individuals. Through its Heisenberg Programme, the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG) enables researchers to pursue high-level projects and thus burnish their academic reputation even further. Sarti is receiving funding worth around €650,000.

When a maize plant is attacked by the fungus Ustilago maydis, tumor-like tissue growths occur at the site of infection. How the pathogen causes this response in its host has long been unknown. But a University of Bonn study has now shown how the fungus takes over the plant’s function for forming lateral roots. The findings have been published in the journal New Phytologist.
