Two international research teams, including scientists from Freie Universität, have independently shown that the Earth partly consists of material that cannot be explained by known meteorite compositions. The studies appeared in Nature and Science. The most common type of meteorites that fall onto Earth are called chondrites, which represent little modified aggregates of dust from the early solar nebula.

Study by the University of Bonn identifies new signaling pathway to combat UV damage and infections Inflammatory reactions in the skin can reduce damage from UV radiation or infections, but can also result in painful symptoms such as sunburn. A recent study at the University of Bonn and the University Hospital Bonn has now identified a molecular control which integrates these stress signals.

Göttingen University geobiologist discovers diversity of patterns in 240 million-year-old seashells UV light makes it possible to see intricate structures of fossils that are barely visible in normal daylight. This method has often been used on the fossilised seashells from the Earth's current geological era to reveal patterns of colour that had long since faded away.

Nanoparticles of cerium dioxide intervene like natural enzymes in biological processes and alter signal molecules / Formation of biofilms is prevented Bacteria love moist surfaces. Once they have settled there, they do not live as solitary organisms but form larger communities that are surrounded by a protective film.

The behavioral strategy allows for mistakes and thus promotes cooperation Understanding mutual cooperation is a key element in understanding how people work together. Whether it is friends doing favors for each other, animals exchanging food or aid, or nations coordinating policies, these are all essentially cooperative interactions.

International research collaboration shows influence of iodine chemistry on formation of new particles in marine atmosphere and recycling of iodine during particle growth The natural cycling of materials between the biosphere and the atmosphere is of great importance to the Earth's climate system. The best known example is the cycling of carbon between the atmosphere, the land biosphere and the ocean.

Drug prevents entry of HD viruses into liver cell Status: October 27, 2022 Infection with hepatits D virus (HDV) causes the most severe form of chronic, viral hepatitis disease. Around ten to 20 million people worldwide are affected. There is no cure for the disease, and in the end the only treatment option is often a liver transplant.

Research team from Freie Universität Berlin demonstrates that spray paints are responsible for high levels of microplastic pollution in soil Public awareness is growing around the subject of microplastics as harmful pollutants. To date, this problematic source of pollution has primarily been investigated in bodies of water.

Cerium dioxide nanoparticles work in biological processes like natural enzymes and change signaling molecules, thereby preventing the formation of biofilms 27 October 2022 Bacteria love moist surfaces. Once they have settled there, they do not live as solitary organisms but form larger communities that are embedded in a protective film.

Study by the University of Bonn elucidates an important immune mechanism Hemophilia A is the most common severe form of hemophilia. It affects almost exclusively males. The disease can usually be treated well, but not for all sufferers. A study at the University of Bonn has now elucidated an important mechanism that is crucial for making the therapy effective.

The lightest neutron star so far found is located at the center of the supernova remnant HESS J1731'347 . Dr. Victor Doroshenko, Dr. Valery Suleimanov, Dr. Gerd Pühlhofer and Professor Andrea Santangelo from the High Energy Astrophysics section of the University of Tübingen's Institute of Astronomy and Astrophysics discovered the unusual object with the help of X-ray telescopes in space.

Mainz University succeeds in the first round of the new Carl Zeiss Foundation Wildcard program / Researchers present an innovative approach for enhancing electronic devices 26 October 2022 Researcher

Finding cannot be explained by classical assumptions. Study under the leadership of the University of Bonn An international team of astrophysicists has made a puzzling discovery while analyzing certain star clusters. The University of Bonn played a major role in the study. The finding challenges Newton's laws of gravity, the researchers write in their publication.

MHH research team finds two promising AAV capsid variants for gene therapy in the liver There are numerous severe, hardly treatable monogenetic diseases that are caused by a defect in a single gene - also in the liver. These include the blood coagulation disorders haemophilia A or B or the metabolic disease phenylketonuria.

Berlin scientists decipher facial motor control in elephants Elephants have an amazing arsenal of face, ear and trunk movements. The trunk consists of far more muscles than the entire human body and can perform both powerful and very delicate movements. A team of scientists from the Humboldt University of Berlin and the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) now examined the facial motor nucleus of African and Asian elephants, the brain structure that controls the facial muscles of these animals.

European Research Council grants international research team almost nine million euros / Experimental physicist at Freie Universität Berlin receives a share of over two million euros Professor Robert Bittl, an experimental physicist at Freie Universität Berlin, is to receive over two million euros through an ERC Synergy Grant from the European Research Council (ERC) as part of a joint international research project.

Scientists at TU Ilmenau have succeeded in improving the accuracy of data evaluations for forecasting weather events, among other things, by up to 80 percent. In the scientific publication ,,Flipped Classroom - Effective Teaching for Time Series Forecasting", which was published in October, Prof. Patrick Mäder, head of the department Data-intensive Systems and Visualization, and Philipp Teutsch, research associate at the same department, present their research results on the training of recurrent neural networks.

New calculations based on fundamental theories deviate from the currently accepted theoretical value The anomalous magnetic moment of the muon is a crucial parameter in particle physics as it allows for precision tests of the established Standard Model. A new measurement of this quantity in 2021 caused a furore as it reaffirmed a significant deviation from the theoretical prediction - in other words, the anomalous magnetic moment is greater than anticipated.

The asteroid Ryugu probably formed at the outer edge of the solar system beyond the gas giants Jupiter and Saturn. This conclusion is suggested by high-precision measurements that determine the ratio of different iron isotopes in rock samples from Ryugu. An international research group with participation of the Göttingen MPI for Solar System Research (MPS) and the University of Göttingen reports these results in the journal Science Advances .

Research team uses CRISPR/Cas technology to repair C282Y mutation in primary haemochromatosis Hereditary primary haemochromatosis is one of the most common inborn errors of metabolism in Europe. In this disorder, also known as iron storage disease, the body is overloaded with iron. The excess iron accumulates in organs and tissues and leads to slowly progressive damage to the liver, heart, pancreas, pituitary gland and joints.
