Retinal damage due to diabetes is now considered the most common cause of blindness in working-age adults. In low- and middle-income countries, an eye examination via smartphone could help to detect changes at an early stage. This is shown by a new study carried out by scientists from the University of Bonn together with colleagues from Sankara Eye Hospital Bangalore (India). The results are published in the journal "Ophthalmology".

Due to the coronavirus pandemic, researchers are currently facing strong restrictions with regard to scientific exchange and mobility. For many, travel restrictions and curfews mean that long-planned trips cannot be undertaken and new positions cannot be started in person. At the University of Bonn, the Welcome Center offers support for those who are “stranded”. Campus reporter Alexander Mertes on the role of “Signs of Life”.

Platelets not only play a key role in blood clotting, but can also significantly intensify inflammatory processes. This is shown by a new study carried out by scientists from the University of Bonn together with colleagues from Sao Paulo (Brazil). In the medium term, the results could open up new ways to treat autoimmune diseases. They have now been published in the renowned journal Cell Reports.

A protein shredder that occurs in cell membranes of brain cells apparently also indirectly regulates the fat metabolism. This is shown by a recent study by the University of Bonn. The shredder, known as gamma-secretase, is considered a possible target for drugs against cancer and Alzheimer's disease. However, the results suggest that such agents may have long-range effects that need to be watched closely. The study has now been published in the journal "Life Science Alliance".

The extent to which Brazilian soy production and trade contribute to climate change depends largely on the location where soybeans are grown. This is shown by a recent study conducted by the University of Bonn together with partners from Spain, Belgium and Sweden. In some municipalities, CO2 emissions resulting from the export of soybean and derivatives are more than 200 times higher than in others. Between 2010 and 2015, the EU imported soy primarily from locations where large forest and savannah areas had previously been converted into agricultural land. The analysis is published in the journal Global Environmental Change.

The district of Heinsberg in the German state of North Rhine-Westphalia is considered a hot spot for the novel Coronavirus SARS-CoV-2. Following a carnival celebration, the district became one of the first areas in Germany where the pathogen spread and infected large quantities of people. As part of the study, a research team led by Prof. Dr. Hendrik Streeck and Prof. Dr. Gunther Hartmann from the University of Bonn carried out a large study to precisely determine the infection fatality rate for the first time among other findings. The results of the study have been pre-published and are now presented to scientists and the public. Publication in a peer-reviewed journal is to follow.

The novel coronavirus Sars-CoV-2 has taken the world by surprise, with devastating consequences for national health systems and the global economy. For years, health experts have been warning of the pandemic risk posed by zoonotic diseases, i.e. infections transmitted from animals to humans. They are demanding the development of monitoring systems that enable quicker responses. Dr. Timo Falkenberg from the Center of Development Research (ZEF) at the University of Bonn is calling for a “One Health” approach that focuses on human, animal and environmental health.

Just a few weeks ago, everyone was talking about plummeting insect numbers. Academic discourse focused on three main causes: the destruction of habitats, pesticides in agriculture and the decline of food plants for insects. A team of researchers from the Universities of Bonn and Zurich and the Swiss Federal Institute for Forest, Snow and Landscape Research WSL have now demonstrated for the first time that the diversity of food plants for insects in the canton of Zurich has dramatically decreased over the past 100 years or so. This means that bees, flies and butterflies are increasingly deprived of their food base. The study, which is representative for all of Central Europe, has now been published in the journal "Ecological Applications".
