Better air due to slurry acidification
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.
Cells refine palm fat into olive oil
For more than 50 years, it has been suspected that fat cells constantly remodel the lipids they store. Researchers at the University of Bonn have now demonstrated this process directly for the first time using culture cells. Among other things, the study shows that the cells quickly eliminate harmful fatty acids. They refine others into molecules that can be used more effectively. In the long term, this turns the components of palm fat into the building blocks of high-quality olive oil, for example. The results have now been published in the journal Nature Metabolism.
A new look at the power houses of cells
The German Research Foundation (DFG) is establishing a new priority program coordinated by the University of Bonn. Prof. Dr. Thomas Becker from the Institute of Biochemistry and Molecular Biology and his colleagues are focusing their attention on how the power houses of the cell (mitochondria) are integrated into the cellular proteostasis network. Proteostasis stands for the basic cell biological processes such as the folding, transport and degradation of proteins. A deeper insight into the interplay of mitochondria and proteostasis network may contribute to better understanding of neurodegenerative diseases and aging processes. The DFG is funding the supraregional network with around 7.8 million euros for an initial period of three years.
New research group on the deformation of structures and infrastructure
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.
How plants adapt to nitrogen deficiency
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.
All Key Players at One Table
The UN Water Conference, held at the United Nations headquarters in New York March 22-24, was attended by Prof. Dr. Mariele Evers, who is the UNESCO Chair for Human-Water Systems at the University of Bonn Department of Geography. Dr. Evers was there as a member of the German government delegation, joined by members and partners of the BonnWaterNetwork.
Statement
As communicated by the University of Bonn on Oct. 26, 2022, allegations of serious misconduct were made against a member of the University's Faculty of Law and Economics in social media.
The current employer of the person accused at the time announced today that an independent investigation had found no conduct corresponding to the allegations.
On the trail of the big questions of particle physics
In seeking an explanation to what holds the world together at its core, particle physicists face many unresolved mysteries. The matter and energy we know make up only five percent of the cosmos; but what is the remaining “dark matter” and “dark energy” made of? Why is there so much matter but so little antimatter in the universe? And why do the second most common known particles in the universe, called neutrinos, have such tiny masses? To answer these fundamental questions, the new Clausius Professor Jun.-Prof. Dr. Lena Funcke and her team are developing models beyond the Standard Model of particle physics and applying novel computational methods for calculating model predictions for future experiments. This will be a new research focus at the University of Bonn in the Transdisciplinary Research Area “Building Blocks of Matter and Fundamental Interactions” (TRA “Matter”).
