Maize can grow successfully in very different local conditions. An international study headed by the University of Bonn has now demonstrated the important role of the plant root system. The researchers analyzed more than 9,000 varieties in the study and were able to show that their roots varied considerably – depending on how dry the location is where each variety was cultivated. They were also able to identify an important gene that plays a role in the plant’s ability to adapt. This gene could be the key to developing varieties of maize that cope better with climate change. The results were recently published in the prestigious journal Nature Genetics.
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.
The transformation of global agricultural and food systems due to climate change, loss of biodiversity, changes in land use and demographic changes poses new challenges for society and politics. The Permanent DFG Senate Commission “Transformation of Agricultural and Food Systems” has the task of researching this change and preparing scientifically sound information.
The state premier of North Rhine-Westphalia, Hendrik Wüst, visited the Humanoid Robots Lab at the University of Bonn on Thursday afternoon. Talks centered on current research projects in the field of robotics and the challenges associated with the use of robots in human environments. The state premier was able to enter virtual reality with a robot and watch a three-armed robot harvesting peppers.
Researchers at the University of Bonn have developed software that can simulate the growth of field crops. To do this, they fed thousands of photos from field experiments into a learning algorithm. This enabled the algorithm to learn how to visualize the future development of cultivated plants based on a single initial image. Using the images created during this process, parameters such as leaf area or yield can be estimated accurately. The results have been published in the journal Plant Methods.
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!
It may be possible to change the purchasing behavior of consumers noticeably using some simple strategies. At least this is what a study, carried out by the University of Bonn and the Technical University of Munich, indicates. The researchers investigated the effect of nudging on the sale of products produced with high animal welfare standards in a virtual supermarket. Nudges are gentle prods or pushes designed to promote certain behaviors – such as placing some products in more visible positions. In the experiment, the participants in the nudging group selected products produced with high animal welfare standards about twice as frequently as the control group. The extent to which these results can be transferred to real purchasing decisions is still unclear. The study has now been published in the journal “Appetite.”
Tiny organisms such as bacteria and fungi help to promote the health and function of plant roots. It is commonly assumed that the composition of these microbes is dependent on the properties of the soil. However, an international team of researchers led by the University of Bonn has now discovered when studying different local varieties of maize that the genetic makeup of the plants also helps to influence which microorganisms cluster around the roots. The results, which have now been published in the prestigious journal Nature Plants, could help to breed future varieties of maize that are better suited to drought and limited nutrients.
