Loneliness is not a disease. And yet it is a significant health problem. Depression, heart disease or dementia - people who are permanently lonely have a higher risk of becoming ill. The team led by Dr. Jana Lieberz from the University Hospital Bonn (UKB), who also conducts research at the University of Bonn, and Prof. Dr. Dirk Scheele (Ruhr University Bochum) have investigated how loneliness can be specifically combated. In a controlled study, in which the universities of Oldenburg, Bochum, Freiburg and Haifa (Israel) were also involved, 78 women and men who felt lonely were given the so-called "cuddle hormone" oxytocin as a nasal spray. The effects that the researchers observed could help to alleviate loneliness and its potentially serious consequences in the future. 

Accessibility is clearly an issue of increasing importance. Lowered curbs, for example, will make it easier for moms and dads out with a stroller to get around in the city. That also applies to individuals who depend on a wheelchair for mobility. Voice command is another useful technology, which helps blind people, for example, use a smartphone. I can also use speech-to-text technology to dictate a text message, while driving a car, for example.

Plants have special corrective molecules at their disposal that can make retrospective modifications to copies of genes. However, it would appear that these “Tipp-Ex proteins” do not have permission to work in all areas of the cell, only being used in chloroplasts and mitochondria. A study by the University of Bonn has now explained why this is the case. It suggests that the correction mechanism would otherwise modify copies that have nothing wrong with them, with fatal consequences for the cell. The findings have now been published in “The Plant Journal.”

Less waste generated by the trauma surgery team at the University Hospital, more vegetarian and vegan food in the canteens, research into ultra-resource-efficient products—the Sustainability Day 2024 showcased everything that the University of Bonn is doing to aid the environmental transformation. Students and staff had taken up Team N’s invitation in their droves and came to find out more about sustainability-related initiatives. Besides a wealth of information on the topic, the over 20 stalls set out on the Poppelsdorf Campus also provided a range of hands-on activities that made one thing clear above all else: sustainability is fun!

Our diet puts a strain on planetary resources. Shifting to a sustainable diet that benefits both our health and that of the planet is therefore assuming increasing importance. Researchers at the University of Bonn have analyzed the diets of children and adolescents in terms of their contribution to the ecological sustainability indicators of greenhouse gas emissions, land use and water use. The study shows that there is both the potential and a need to make the diet of younger generations more sustainable. The study will be published in the American Journal of Clinical Nutrition; it is already available online.

Strongly interacting systems play an important role in quantum physics and quantum chemistry. Stochastic methods such as Monte Carlo simulations are a proven method for investigating such systems. However, these methods reach their limits when so-called sign oscillations occur. This problem has now been solved by an international team of researchers from Germany, Turkey, the USA, China, South Korea and France using the new method of wavefunction matching. As an example, the masses and radii of all nuclei up to mass number 50 were calculated using this method. The results agree with the measurements, the researchers now report in the journal “Nature”.

The North Rhine-Westphalian Academy of Sciences, Humanities and the Arts welcomed 10 new members at its annual ceremony. The new recruits include two from the University of Bonn: the soil scientist Professor Wulf Amelung and the computer scientist Professor Stefan Wrobel, who is also Director of the Fraunhofer Institute for Intelligent Analysis and Information Systems (IAIS). The four women and six men are united by exceptional research work and creative excellence in their area of expertise. 

Plants adapt genetically over time to the special conditions of organic farming. This has been demonstrated in a long-term study conducted at the University of Bonn. The researchers planted barley plants on two neighboring fields and used conventional farming methods on one and organic methods on the other. Over the course of more than 20 years, the organic barley was enriched with specific genetic material that differed from the comparative culture. Among other things, the results demonstrate how important it is to cultivate varieties especially for organic farming. The results have now been published in the journal “Agronomy for Sustainable Development.”
