The whiskered brome (Bromus grossus) is an ancient cereal species that is known to have been cultivated and used as a food resource as early as the Bronze Age. Today, however, it is threatened with extinction. In joint research work, the University of Bayreuth, the Bezirkslehrgut Bayreuth and the company IREKS in Kulmbach have investigated whether the grain from this species is suitable for brewing beer. The result is two tasty beers: a Pilsner and a Hefe-Weizen.
Rising incomes in the world's poorer countries weaken terrorism: many political decision-makers have been convinced of this since the attacks of September 11, 2001. However, a study by Bayreuth economist Prof. Dr. David Stadelmann published in the "Journal of Conflict Resolution" puts this view into perspective. Together with research partners in Abu Dhabi/UAE and Perth/Australia, he demonstrates that an increase in income in poorer countries is initially accompanied by an increase in terrorist activity. Only when average incomes reach a level of around $12,800 do further increases in income go hand in hand with a sustained weakening of terrorism.
A transformation of the energy supply that replaces fossil fuels with renewable energy sources requires new powerful technologies for storing electricity generated by the sun and wind. One promising technology is Carnot batteries, which temporarily store electricity in the form of heat. A new project of the Chair of Technical Thermodynamics and Transport Processes (LTTT) in the Center of Energy Technology (ZET) at the University of Bayreuth is investigating optimal working fluids for these energy systems. As part of the DFG Priority Programme 2403 "Carnot batteries: Inverse design from markets to molecules", it will initially be funded for three years with a total of around 298,000 euros.
The responsible institutions are the University of Bayreuth and the Technical University of Applied Sciences Augsburg: close cooperation in the future fields of digitization.
An international research team led by Prof. Dr. Tomoo Katsura at the Bavarian Research Institute of Experimental Geochemistry and Geophysics, University of Bayreuth, has discovered why rocks in the Earth's interior suddenly become more viscous at depths of 800 to 1,200 km. The cause of this change is the bridgmanite-enriched rocks that make up most of the Earth's lower mantle below about 1,000 km. These rocks have a much larger grain size than the rocks above them, resulting in high viscosity. The new findings have been published in the journal "Nature".
A team at the Department of Plant Systematics at the University of Bayreuth has recently identified a new plant species of the genus Leichhardtia on New Caledonia and presented it in the journal "Phytotaxa". This discovery was triggered by a television report from a local TV station on New Caledonia about a research trip to the hard-to-access island of Yandé northwest of the main island of New Caledonia.
Prof. Dr. Christoph Helbig, Chair of Ecological Resource Technology at the University of Bayreuth, is investigating framework conditions and measures for the circular economy on an international level in his latest project, using the example of electronics and electric vehicle batteries. The goal is to come up with concrete proposals for a more efficient and environmentally friendly circular economy.
In the northwest of the Republic of Chad, in a remote desert region of the Tibesti Mountains, there are irrigated gardens divided into floors for the cultivation of fruits, vegetables, herbs and dates. Dr. habil. Tilman Musch, a social anthropologist at the University of Bayreuth, established these Sahara gardens in close cooperation with local residents. He reports on the goals, challenges and successes of the project, which has been funded by the Gerda Henkel Foundation since 2021 and follows on from earlier traditions of oasis horticulture in the Sahara, in the journal "Berichte über Landwirtschaft" published by the German Federal Ministry of Food and Agriculture (BMEL).
Most plants worldwide live in symbiosis with fungi. Often there is an exchange of nutrients from which both partners benefit. In numerous other cases, however, the plants feed unilaterally at the expense of the fungi. International research groups led by Prof. Dr. Gerhard Gebauer at the University of Bayreuth have now presented a groundbreaking method in the journal "New Phytologist" that makes it possible for the first time to apply isotope analyses to all forms of symbiosis between plants and fungi without restrictions. In principle, it will be possible in the future to determine for each plant which and how many nutrients it obtains from fungal partners.
A new study by Bayreuth scientists Dr. Franz-Sebastian Krah and Prof. Dr. Claus Bässler has shown that temperature has a significant influence on the timing and duration of fungal fruiting in key areas of the world. The research results were published in the journal "Ecology Letters" and shed new light on the global impact of climate change on occurrences of fungi in nature.
