Can surgeons quantify the risk of aphasia when removing a brain tumor? To find out, researchers at Klinikum rechts der Isar of the Technical University of Munich (TUM) are analyzing the brain as a network. In a current study with 60 patients, they already achieved an accuracy rate with three quarters of their predictions.
Female putty-nosed monkeys deliberately use alarm calls to recruit males to defend the group. This is the conclusion reached by Claudia Stephan, an evolutionary biologist at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), together with colleagues from the Wildlife Conservation Society after conducting observations in the Republic of the Congo. The females kept up their chirping calls until the male took action to defend the group against the predator. This is the first time that intentional vocalization such as this has been observed in the animal kingdom. The researcher has now published her findings in the scientific journal “Animal Behavior and Cognition".
Increased cell proliferation is a key feature of diseases such as cancer. A research team from the University of Würzburg and two Leibniz Institutes has now succeeded in indirectly influencing this process.
The better we understand cellular processes such as RNA regulation, the better molecular therapies can be developed. Until now, it has been especially difficult to track the regulation of non-coding RNA, which is RNA that is not further converted into proteins. A research team from the Technical University of Munich (TUM) and Helmholtz Munich has now developed a minimally invasive reporter system that enables highly sensitive monitoring of RNA production of both coding and non-coding RNA.
A German-Czech research team presents a new binational data infrastructure. The project "Flora of the Bohemian Forest" has made scientific data available from historical species monitoring projects in both countries as well as new data on the current plant diversity of the Bohemian Forest. The data is publicly online available in German and Czech language. The scientists, on the Bavarian side led by the Bavarian Natural History Collections (SNSB), recently published their results in the Biodiversity Data Journal. The established services will be further developed in the coming years within the framework of the NFDI4Biodiversity Consortium and the SNSB data project on the flora of Bavaria.
The origin of SARS-CoV-2 remains unresolved. In a non-peer-reviewed preprint published on BioRxiv on Oct. 20, 2022 three authors present analyses that, according to their interpretation, suggest a "synthetic emergence" of SARS-CoV-2 and its release in the context of a "laboratory accident". Experts from the University of Wuerzburg and the University Hospital have reviewed the preprint on the origin of SARS-CoV-2. In summary, the analyses presented in the study do not provide sufficient evidence for the authors’ conclusion that SARS-CoV-2 is of synthetic origin.
Water-soluble synthetic polymers (WSSPs) are found in many everyday products. What the consequences are when these plastics enter rivers, lakes and oceans is still largely unexplored. A team from the University of Bayreuth has now systematically investigated the effects on water fleas of the species Daphnia magna for the first time. The polymers selected for testing significantly alter the body size and reproduction of the animals in some cases. The research, published in Science of The Total Environment, shows that water-soluble polymers could have consequences for biodiversity and food chains in aquatic ecosystems that should not be underestimated.
At the beginning of the corona pandemic, the R0 value was an essential criterion for estimating the further development. A study by the University of Würzburg now shows that it was often not really accurately determined.
Myanmar, a country in Southeast Asia, is plagued by political and economic crises. The fall of a president, a military putsch and the crackdown on religious minorities have had an impact not only on life but also on research in the country. One area of research that has been particularly affected is research into fossils preserved in amber. Researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have conducted a case study proving the negative impact political conflicts have on research. They examined scientific publications from the last three decades describing fossils in amber from Myanmar.
When searching for the causes of illnesses and developing new treatments, it is absolutely vital to have a precise understanding of the genetic fundamentals. Würzburg researchers have devised a new technique for this purpose.
