Nudging in a virtual supermarket for more animal welfare

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.”

Borders Are Arbitrary, but Inviolable

Everyone has the right to visit and reside in a foreign country: thus a central aspect of Immanuel Kant’s doctrine of global citizenship. In this interview, Professor Christoph Horn (University of Bonn) from the Digital Kant Center NRW explains Kant’s view of migration, why he considered the drawing of borders to be arbitrary, and the contemporary relevance of this doctrine.


Research Studying Research

In what ways do evaluation and reward systems influence the conduct and results of research studies? This is the question addressed by Dr. Oliver Braganza of the University of Bonn and University Hospital Bonn, in collaboration with researchers from the University of Utrecht, the University of Duisburg-Essen and colleagues from the University of Bonn. Titled “The cultural evolution of scientific practice—from simulation to experimentation,” the project is to receive around 1.8 million euros in funding from the Volkswagen Foundation over the next four years.

Fossils Permit Glimpse into the Future

In what is an intriguing mix of past and future, an international team of researchers, including some from the University of Bonn, has stumbled upon a surprising window to the past in Kourou in French Guiana. In the clay underneath the new launch pad for the forthcoming Ariane 6 launch vehicle, the interdisciplinary team has uncovered a remarkable collection of fossils stretching back 130,000 years. Covering over 270 species in total, including bony fish, sharks and numerous plants, they reflect the kind of climatic conditions that calculations suggest are set to reoccur in the year 2100. The team’s findings have now been published in the “Proceedings of the National Academy of Sciences of the USA.”

Don Zagier Awarded Germany’s Biggest Mathematics Prize

The Carl Friedrich von Siemens Stiftung is to present the Heinz Gumin Prize for Mathematics to Don Zagier, who was a director of the Bonn-based Max Planck Institute for Mathematics until 2019 and has strong ties to the University of Bonn. The foundation is thus honoring his pioneering research into number theory and the theory of modular forms. The Gumin Prize is worth €50,000, making it the most generous award for mathematics in Germany. 

All Countries’ Agri-Environmental Policies at a Glance

There can be no analysis without data. In this spirit, researchers from the University of Bonn and the Swiss Federal Institution of Technology (ETH) Zurich have published a database containing over 6,000 agri-environmental policies, thus enabling their peers as well as policymakers and businesses to seek answers to all manner of different questions. The researchers have used two examples to demonstrate how this can be done: how a country’s economic development is linked to its adoption of agri-environmental policies and how such policies impact soil erosion. Their study has now been published in “Nature Food.”

Maize genes control little helpers in the soil

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.

Phosphorus Absorption Improved and Zinc Content Increased

A new variety of rice that is adapted to life in low-phosphorus soils, that contains an exceptionally large amount of zinc and that was developed specifically for the conditions in Madagascar where it is grown, has recently been certified in the country. The variety was created under the leadership of plant scientist Professor Matthias Wissuwa from the Japan International Research Center for Agricultural Sciences (JIRCAS) and the PhenoRob Cluster of Excellence at the University of Bonn which he joined as a visiting professor in spring 2023,  together with the Africa Rice Center and the National Centre of Applied Research for Rural Development in Madagascar (FOFIFA)
