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.

Constantly increasing data volumes, ever more complex calculation and modeling—working with large amounts of data is crucial in many fields of research. The new high-performance computer "Marvin" now makes it easier for University of Bonn researchers to leverage artificial intelligence and machine learning. Featuring a scalable GPU partition, Marvin is among the world’s top 500 most powerful computers. Funded in part under the Excellence program, the acquisition of Marvin comes as part of the University of Bonn digital strategy. 

Which sustainability goals do people in Germany find more important: Animal welfare? Or environmental protection? Human health is another one of these competing sustainability goals. A team of researchers from the Department of Agricultural and Food Market Research at the University of Bonn have now found that consumers surveyed in their study would rather pay more for salami with an “antibiotic-free” label than for salami with an “open barn” label that indicates that the product promotes animal welfare. The results have now been published in the journal “Q Open.”

Projects that reduce deforestation often sell carbon credits - for instance, to consumers purchasing airline tickets. However, over 90 percent of these project credits do not actually offset greenhouse gas emissions. This is the conclusion of a study conducted by the Vrije Universiteit Amsterdam (Netherlands), the University of Bonn, the University of Cambridge (United Kingdom) and the European Forest Institute in Barcelona (Spain). It was carried out on an exemplary basis for 26 projects in six countries. The results have now been published in the renowned journal Science.

A novel catalysis scheme enables chemical reactions that were previously virtually impossible. The method developed at the University of Bonn is also environmentally friendly and does not require rare and precious metals. The researchers recorded the exact course of the catalysis in a kind of high-speed film. They did this using special lasers that can make processes visible that last only fractions of a billionth of a second. The results allow them to further optimize the catalyst. They have been published in the international edition of the renowned journal “Angewandte Chemie.”

Innovative production methods are needed in order to tackle global challenges such as climate change, population growth and ecosystem loss. This has put strategies for a sustainable bioeconomy that place greater emphasis on using renewable raw materials firmly on the political agenda, both in Europe and around the world. When pursuing strategies of this kind, however, it is important to get the people who will be affected on board first. This is the finding from a study that three researchers from the Institute for Food and Resource Economics at the University of Bonn have recently published in the journal “Technology in Science.”

Gases that are harmful to health and the climate are produced wherever livestock are kept. Although there are various ways of supposedly reducing these emissions, it is often impossible to say with any certainty how effective they are. This is because recording precise levels of harmful gases has so far been a laborious, costly and time-consuming process. A Germany-wide joint project is now setting out to change that with the help of more than €10,5 million in funding from the Federal Ministry of Food and Agriculture. The official funding certificate has been presented yesterday by Agriculture Minister Cem Özdemir at a ceremony in Potsdam. Among other things, the methods being developed are intended to identify particularly efficient ways of reducing emissions.

The Belgian research vessel RV Belgica is currently underway in the waters of Iceland. Two researchers from the University of Bonn are also on board. The goal of the mission is to better understand a natural thermostat of the Earth: the weathering of rocks at the bottom of the sea. This process binds carbon dioxide from the atmosphere. It may also be possible to use it in the fight against climate change.

What legal levers can cities pull in order to reinvent themselves as green, equitable, productive and healthy places to live in the spirit of the New Leipzig Charter of 2021? What legal constraints are they subject to? And what answers do constitutions provide to the question of an environmentally sustainable transformation and the social sustainability challenges that it brings? These and other questions are being tackled by the legal expert Jun.-Prof. Dr. Jacqueline Lorenzen, a new Argelander Professor at the University of Bonn. Within the Individuals, Institutions and Societies Transdisciplinary Research Area (TRA), she is working at the interface between law, economics and the social sciences.

What impact does artificial intelligence (AI) have on the environment? And what might the ramifications of AI be for society? These are some of the questions being tackled by the research group led by Prof. Dr. Aimee van Wynsberghe, a Humboldt Professor at the University of Bonn. Last week, she brought together international experts in the research field.

How can people work together to forge new, environmentally sustainable paths in a complex system? This is the question being tackled by Jun.-Prof. Dr. Wolfram Barfuss, the new Argelander professor in the Innovation and Technology for Sustainable Futures Transdisciplinary Research Area (TRA Sustainable Futures) at the University of Bonn. He is developing mathematical models for collective learning and linking different research areas, including complex systems, artificial intelligence and social ecology, in order to identify key levers for easing the transition to sustainability. Barfuss and his team are based at the Center for Development Research (ZEF).

What impact does artificial intelligence (AI) have on the environment? And what might the ramifications of AI be for society? These are some of the questions being tackled by the research group led by Prof. Dr. Aimee van Wynsberghe, a Humboldt Professor at the University of Bonn. She will now bring international experts in the field together between May 30 and June 1. At the Universitätsclub Bonn, the researchers will discuss cross-cultural perspectives of sustainable AI on a global level.

German consumers consider paper-based packaging to be particularly environmentally friendly. Nevertheless, they tend to be skeptical about innovative products such as paper-based bottles. This is shown by a recent study by the University of Bonn and Forschungszentrum Jülich. Almost 3,000 women and men from all over Germany were surveyed for the study. The results have now been published in the journal “Food Quality and Preference.”

At the career fair organized by the Cluster of Excellence PhenoRob together with the Faculty of Agriculture and the Theodor Brinkmann Foundation students, PhD students and graduates of the University of Bonn were able to expand their professional network and make new contacts.

Roads, bridges and dams age. How long can such structures still bear the weight? The new research group “Deformation Analysis with Terrestrial Laser Scanner Measurements (TLS-Defo)” at the University of Bonn wants to make a step forward in answering these questions. The German Research Foundation (DFG) will fund the group with around 2.4 million euros over the next four years.

Large quantities of excrements are produced in livestock farming. When it is stored in the barn and spread on the fields as fertilizer, ammonia is produced. The gas is harmful to health and also significantly pollutes the environment. A retrofit solution for existing barn systems promises a remedy: A study by the University of Bonn shows that this can reduce ammonia emissions by around 40 percent just inside the barn. It reduces the production of methane, a powerful greenhouse gas, even more significantly. The method could therefore also make an important contribution to the fight against climate change. The results will be published in the Journal of Environmental Management, but are already available online.

Nitrogen as a fertilizer can increase yields. However, too much nitrogen can also have negative effects, such as groundwater pollution, high energy consumption in fertilizer production and the generation of climate-relevant gases. Science is therefore looking for ways to help crops thrive with less nitrogen. Researchers at the University of Bonn have discovered gene variants of the nitrate sensor NPF2.12 that trigger a signal cascade chain at low soil nitrogen levels. This induces stronger root growth, resulting in improved nitrogen utilization. The study had already been published online in advance in "New Phytologist." The final version has now been published.

Some plants can survive months without water, only to turn green again after a brief downpour. A recent study by the Universities of Bonn and Michigan shows that this is not due to a “miracle gene.” Rather, this ability is a consequence of a whole network of genes, almost all of which are also present in more vulnerable varieties. The results have already appeared online in advance in the journal "The Plant Journal". The print edition will be published soon.

Students and graduates of the University of Bonn are welcome to participate in the first PhenoRob Career Fair to expand their professional network.

Livestock farming produces large quantities of greenhouse gases, especially methane, which is particularly harmful to the climate. Among other things, it escapes during the storage of animal excrement, the slurry. A study by the University of Bonn now shows that methane emissions can be reduced by 99 percent through simple and inexpensive means. The method could make an important contribution to the fight against climate change. The results have now been published in the journal Waste Management.

The EU regularly exports large quantities of poultry meat to West African countries. These exports have been criticized for harming importing countries in West Africa and exacerbating poverty there. The reason: Cheap imports depress the local price of chicken, making life difficult for local smallholders. Researchers at the Universities of Bonn and Göttingen have now used the example of Ghana to calculate the effects that would result if the country were to significantly increase its import tariffs for poultry meat or even stop imports completely. The result: Prices would indeed rise domestically, but most local households would not benefit. The study has been published in the journal Food Security.

Young people would accept a lower salary for a job in a sustainable or socially oriented company. This is what a team led by Thomas Dohmen, professor at the Cluster of Excellence ECONtribute at the University of Bonn, has discovered.

For outstanding achievements in the fight against hunger and rural poverty, the Foundation fiat panis has awarded the Justus von Liebig-Award for World Nutrition for the seventh time. This year it goes to the Dutch agricultural and nutrition expert Prof. Dr. Louise O. Fresco. The award ceremony took place at the Center for Development Research (ZEF) at the University of Bonn. Fresco gave a lecture on "Where Are We in Understanding World Hunger" as part of the Distinguished Lectures Series of the Transdisciplinary Research Area "Sustainable Futures" at the University of Bonn.

Tropical deforestation causes widespread degradation of biodiversity and carbon stocks. Researchers from the German Center of Integrative Biodiversity Research (iDiv) and Leipzig University were now able to test the relationship between land tenure and deforestation rates in Brazil. Their research, which was published in Nature Communications, shows that poorly defined land rights go hand in hand with increased deforestation rates. Privatising these lands, as is often promoted in the tropics, can only mitigate this effect if combined with strict environmental policies.

The University of Bonn, the University of Cologne and Forschungszentrum Jülich are placing their joint Center for Earth System Observation and Computational Analysis (CESOC) on a new contractual footing. As a joint scientific facility of the three partner institutions, an internationally visible focal point has been created to globally observe and comprehensively understand the Earth system and to predict changes. The center is additionally strengthened by a memorandum of understanding now signed with the European Centre for Medium-Range Weather Forecasts (ECMWF), which has moved to Bonn in 2021.

A new study led by the University of Tasmania – with the participation of the University of Bonn – discovered the oldest marine DNA in deep-sea sediments of the Scotia Sea north of the Antarctic continent. The material could be dated to one million years. Such old material demonstrates that sedimentary DNA can open the pathway to study long-term responses of ocean ecosystems to climate change. This recognition will also help assessing current and future change of marine life around the frozen continent. The study appeared in the journal Nature Communications.

How do pollution and climate change affect health and the associated costs? How do people adapt to their environmental conditions, and what factors are crucial for such adaptability? Julia Mink, new Argelander Professor at the University of Bonn, addresses these and other questions. In the Transdisciplinary Research Area "Individuals, Institutions and Societies", she will work at the interface of environmental and health economics.

The Academy of Sciences and Literature has admitted six new members. Among them is Humboldt Professor Aimee van Wynsberghe. The AI ethicist from the University of Bonn has become a full member of the Humanities and Social Sciences Class.

How effective is biodiversity conservation of European and African national parks? This seems to be strongly associated with societal and economic conditions. But even under the most favourable conditions, conservation efforts cannot completely halt emerging threats to biodiversity if conditions outside of the parks do not improve. This is the conclusion of a new study led by the German Centre for Integrative Biodiversity Research (iDiv), the Max Planck Institute for Evolutionary Anthropology (MPI EVA), and the University of Bonn, in collaboration with the Helmholtz Centre for Environmental Research (UFZ), Leipzig University, the Friedrich Schiller University Jena and many other institutions. The study published in the journal Nature Sustainability highlights the urgent need for a better design of national park networks.

Not only in the sea, but also in our soils there is "invisible" plastic - nanoplastics to be precise. This is a problem because it can be absorbed by plants and thus enter the food chain. But how much of such plastic is actually hiding in the soil? To find out, Dr. Melanie Braun from the University of Bonn wants to develop a new method. For her innovative project, the junior scientist has now received the Klaus Töpfer Research Prize worth 50,000 euros, which is awarded internally by the Transdisciplinary Research Area "Innovation and Technology for Sustainable Futures" (TRA Sustainable Futures) at the University of Bonn. The prize was named after Prof. Dr. Klaus Töpfer, former Federal Minister for the Environment and pioneer of climate policy, who was a guest at the award ceremony.

How can new and environmentally friendly materials be developed, tested and optimized? And how can primary raw materials be reused in the best possible way? To support industrial and university research groups in these issues, more than 50 research infrastructures in Europe have now joined forces. Among them are researchers from the Center for Advanced Security, Strategic and Integration Studies (CASSIS) at the University of Bonn. They bring a social science perspective to strategic sustainability research and will receive 317,000 euros. The European Commission is providing a total of 13.6 million euros for the project.

The University of Bonn has once again received excellent reinforcement. The internationally renowned anthropologist, curator and critical heritage specialist Paul Basu now occupies a so-called Hertz Professorship in the Transdisciplinary Research Area "Present Pasts". The starting point for his work is a critical engagement with the heritage of Western knowledge production, especially as it is reflected in scientific archives and collections. In doing so, he brings together different disciplines, but also the non-university public.

How does international trade in agricultural and forest products affect biodiversity? A research project led by the University of Bonn will investigate this question, particularly for animal feed, energy crops, tropical timber and aquacultures. In collaboration with stakeholders from politics, the private sector and civil society, the researchers will develop innovative solutions for more sustainable production and consumption. The European Union is funding the project with around 2.6 million euros over the next three years, of which around 850,000 euros will go to the University of Bonn. Funding has been granted for other projects.

Artificial intelligence (AI) is getting a boost: the German Research Foundation (DFG) is funding a total of eight new AI research units with a total of 31.4 million euros. Two projects from the University of Bonn in the fields of geodesy and precision agriculture are among them. The millions in funding will flow over the next four years. An extension is possible.

The Green Learning Workshop opened its doors in the University of Bonn’s Botanic Gardens. It is set to run age-appropriate programs that will enable children to discover the diversity of plant life in a fun way and embark on their own research projects. The learning workshop will be open all year round, come rain or shine, and will complement the activities of the Green School. Its premises were renovated and fitted out thanks to funding from the University of Bonn Foundation, the University of Bonn and numerous other supporters.

Southern Africa has a rich bounty of crop varieties, crop wild relatives, orphan crops and underutilised plant species, collectively known as plant genetic resources for food and agriculture (PGRFA), which have sustained generations of local farmers and rural communities and enabled them to cope with changing environmental conditions. The project "Farmer Resilience and Melon Crop Diversity in southern Africa" (FRAMe) aims at a future-oriented agriculture of crop diversity using melons as an example. The German Federal Ministry of Education and Research (BMBF) is funding the project with more than 300,000 euros over the next three years.

"An apple a day keeps the doctor away" is an old English saying that means apples are healthy, so you should eat one every day. A very special specimen is the type "Adams Parmäne", which is currently on the red list of endangered native crops in Germany. The Wiesengut Teaching and Research Station at the University of Bonn is working with pomologist Barbara Bouillon from the "Biologische Station im Rhein-Sieg-Kreis" to preserve this special apple variety. She shows how this can work and why it is so important right now.

People who have a critical attitude toward factory farming or who pay attention to their health in everyday life are more likely to turn to meat substitutes. Concern for the environment, on the other hand, plays no role in this decision. This is the conclusion of a study conducted by the University of Bonn in which more than 400 people between the ages of 17 and 86 took part. The results appear in the journal Food Quality and Preference.

If our planet Earth is to continue feeding us in the future, rich countries must significantly reduce their meat consumption - ideally by at least 75 percent. This is the conclusion of a new study by the University of Bonn. The study reviews the current state of research on various aspects of meat consumption. In addition to the effects on the environment and climate, these include health and economic effects. A conclusion of the researchers: Eating meat in small amounts can be quite sustainable. The results are published in the journal Annual Review of Resource Economics.

How can digital technologies be used for more sustainable crop production? Researchers from a wide range of disciplines are working on these questions at the Cluster of Excellence PhenoRob at the University of Bonn. At the Cluster's flagship conference, DIGICROP from March 28–30, experts pool their knowledge, bringing together distinguished speakers from around the world. The Cluster of Excellence is receiving support from the AI Institute for Next Generation Food Systems (USA). Registrations for the digital, English-language conference are open until March 24.

The Center for Development Research (ZEF) at the University of Bonn will receive around eight million Euros in funding over the next eight years from the International Climate Initiative of the German Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection. The new CABES (Capacities on Biodiversity and Ecosystem Services) project aims to strengthen the interfaces between science, policy and practice in Africa and support networking with the international activities of the World Biodiversity Council (IPBES). Another goal of the project is to train early career scientists as intermediaries. To this end, new Master degree programs are being established in Côte d'Ivoire, Ethiopia and the Democratic Republic of Congo (DRC).

Artificial intelligence (AI) is transforming society as algorithms increasingly impact access to jobs and insurance, justice, medical treatments, as well as our daily interactions with friends and family. As these technologies race ahead, we are starting to see unintended social consequences: algorithms that promote everything from racial bias in healthcare to the misinformation eroding faith in democracies. To ensure AI supports core human values, the German philanthropic foundation Stiftung Mercator has awarded a €3.8 million grant to a collaboration between the Universities of Bonn and Cambridge.

The use of genetically modified (GM) crops in agriculture remains contentious, especially in Europe. According to surveys, many people fear that these could have negative effects for human health and the environment. However, a new study shows that genetically modified crops could actually be good for the environment, and for the climate in particular. Results suggest that the adoption of GM crops in the European Union (EU) could reduce greenhouse gas emissions considerably. The study by scientists from the Breakthrough Institute in the USA and the University of Bonn in Germany was recently published in “Trends in Plant Science”.

Prof. Dr. Anne-Katrin Mahlein, co-opted professor at the University of Bonn and Director of the Institute of Sugar Beet Research (Göttingen) is the most cited author in the research field sensing and imaging of plant disease. According to a publication by the journal “Tropical Plant Pathology”, Mahlein’s research has significantly pushed this area of research forward. Overall, the University Bonn has been determined to be the most productive and most collaborative institution in the field.

Now the Sustainable AI Lab at the University of Bonn is officially launched being a space for excellent researchers from different fields to work, collaborate, and brainstorm about the environmental, social, and economic costs of designing, developing, and using AI across society.

Which diet is better: moderately reduce meat consumption and eat more fruit, vegetables and wholegrain products, as recommended by the German Nutrition Society? Follow our southern neighbors' example and eat more fish and seafood? Or even switch completely to a vegan diet? A new study by the University of Bonn shows that the answer to these questions is not as clear-cut as one might think - depending on which impacts one closely looks. The results are published in the journal Science of The Total Environment.

Great success for two research collaborations at the University of Bonn: The Collaborative Research Centre Transregio (CRC-TRR) 224 "Economic Perspectives on Societal Challenges" and the CRC-TRR 228 "Future in Rural Africa" have convinced with their research work of the past four years. The German Research Foundation (DFG) is therefore funding both collaborations for a further funding period with several million euros each. In the CRC-TRR 224 project, scientists from the Universities of Bonn and Mannheim are jointly opening up economic perspectives on social challenges. The CRC-TRR 228 project brings together researchers from the Universities of Bonn and Cologne, the Bonn International Centre for Conflict Studies (BICC) and the German Development Institute (DIE) to work on shaping the future of rural Africa.

New boost for excellent research at the University of Bonn: The German Research Foundation (DFG) is establishing two new Collaborative Research Centres (CRC). In the CRC 1502 "Regional Climate Change: The Role of Land Use and Water Management", researchers are investigating the hypothesis that human-induced land use change and intensified water management influence the regional climate. The speaker of the consortium is Prof. Dr. Jürgen Kusche. In the Transregio-CRC 333 "Brown and Beige Fat Organ Crosstalk, Signaling and Energetics ( BATenergy)", the research teams are looking at different types of adipose tissue and their role in metabolic diseases. The network is a collaboration of the Universities of Bonn and the University Hospital Bonn, the University Medical Center Hamburg-Eppendorf (UKE), the Technical University of Munich (TUM) and the Helmholtz Zentrum München. The speaker is Prof. Dr. Alexander Pfeifer.

On November 25 the Bonn Sustainable AI Lab at the University of Bonn will have its official launch event. A wide range of highly regarded speakers like Katja Dörner, Mayor of Bonn, Patricia Espinosa, Executive Secretary of UN Climate Change, Dr. Enno Aufderheide, Secretary General of the Humboldt Foundation and Jan Kleijssen, Council of Europe, will address the impact of Artificial Intelligence (AI) on society and express the urgency to conduct more research and experiments on AI to get a grip on its rapid development. The Rector of the University of Bonn, Prof. Dr. Dr. h. c. Michael Hoch, and the co-director of the Institute of Science and Ethics (IWE) and head of the Sustainable AI Lab, Prof. Dr. Aimee van Wynsberghe, will perform the opening ceremony. Journalists can attend the event after registration. The start is at 16:00.

After the natural warming that followed the last Ice Age, there were repeated periods when masses of icebergs broke off from Antarctica into the Southern Ocean. A new data-model study led by the University of Bonn now shows that it took only a decade to initiate this tipping point in the climate system, and that ice mass loss then continued for many centuries. Accompanying modeling studies suggest that today's accelerating Antarctic ice mass loss also represents such a tipping point, which could lead to irreversible and long-lasting ice retreat and global sea level rise. The study has now been published in the journal Nature Communications.
