Meat consumption must fall by at least 75 percent¹

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.

Enzyme prevents brain activity from getting out of control²

The brain has the ability to modify the contacts between neurons. Among other things, that is how it prevents brain activity from getting out of control. Researchers from the University Hospital Bonn, together with a team from Australia, have identified a mechanism that plays an important role in this. In cultured cells, this mechanism alters the synaptic coupling of neurons and thus stimulus transmission and processing. If it is disrupted, diseases such as epilepsy, schizophrenia or autism may be the result. The findings are published in the journal Cell Reports.

No glacial fertilization effect in the Antarctic Ocean³

Can iron-rich dust fertilize the ocean, stimulate algae growth there, and thereby capture carbon dioxide from the atmosphere? An international research team led by the University of Bonn used deep-sea sediment cores from the Scotia Sea to investigate whether this hypothetical greenhouse gas sink had an effect during ice ages. Although dust input was high during ice ages, no evidence of a fertilization effect could be found in the Antarctic Ocean. Rather, the production of algae, for example, and thus carbon dioxide sequestration, was high only during warm periods when dust input was low. The study has now been published in "Nature Communications."

New approach against chronic inflammation⁴

Researchers at the Universities of Bonn and Sao Paulo have succeeded in mitigating chronic inflammation in mice using customized "mini-antibodies." These nanobodies enabled them to dissolve molecular complexes in tissue that normally activate the immune system. The nanobodies produced may in future help to slow down unwanted inflammatory reactions that cause diseases such as arthritis or neurodegeneration. The study is published in the journal EMBO Molecular Medicine.

The cherry blossom squares⁵

Just on time for the start of the Bonn Cherry Blossom Festival, geodesists from the University of Bonn have taken advantage of social media to visualize where the blossoms are hiding in Bonn.

Control, coercion, and constraint in religion⁶

What role does religion play in both overcoming existing and creating new forms and types of dependencies? This question will be explored in the second part of the lecture series organized by the Centre for Religion and Society (ZERG) and the Cluster of Excellence Bonn Center for Dependency and Slavery Studies (BCDSS). The lecture series will now take place every Tuesday at 6:15 p.m. in the University's main building and will also be livestreamed.

Protein boosts height growth in girls⁷

Quite a few young men would like to increase their height. However, a study by nutritionists at the University of Bonn shows that they do not benefit from increased protein intake in terms of their adult height. In contrast, young women often see it as problematic when their height significantly exceeds 1.80 meters. Here, during growth, a protein intake adapted to the recommendations can even cause a reduction of a few centimeters. The results have been published online in advance in the Journal of Clinical Endocrinology and Metabolism. The final version will appear soon.

Film series and discussion: Who’s Got the Power?⁸

Who's Got the Power? This is the question addressed in a new film series by the Center for Dependency and Slavery Studies (BCDSS) at the University of Bonn and Förderverein Filmkultur, a film funding association in Bonn. The launch of the film series marks the start of a multi-year cooperation between these two institutions. The films will examine various scenarios of human oppression and strong asymmetrical dependency relationships, beginning with the award-winning film "La Pirogue" by Moussa Touré on April 28 at 8 p.m. at the Kino in der Brotfabrik, Bonn (Kreuzstraße 16). The format “screening plus talk” will offer a space for researchers, film makers, and the public to enter into a dialogue.
