Freiburg researchers develop new formal description of internal world models, thereby enabling interdisciplinary research A team of scientists led by Ilka Diester , Professor of Optophysiology and spokesperson of the BrainLinks-BrainTools research centre at the University of Freiburg, has developed a formal description of internal world models and published it in the journal Neuron .

International research team led by scientist from Freie Universität Berlin proposes that elevated levels of antibiotic resistance genes be considered a new factor of global change Human-caused global change is a complex phenomenon comprising many factors such as climate change, environmental contamination with chemicals, microplastics, light pollution, and invasive plants.

Bonn researchers solve the hidden mystery of the role of astrocytes for learning processes and memory in the brain Star-shaped glial cells, so-called astrocytes, are more than just a supporting cell of the brain. They are actively involved in learning processes and interact with the nerve cells. But what exactly is it that astrocytes do? Researchers at the University Hospital Bonn (UKB) and the University of Bonn are using a biophysical model to clarify how astrocytes interact with nerve cells to regulate rapid adaptation to new information.

A team at the Helmholtz Centre for Infection Research in Würzburg, Germany, led by RNA expert Chase Beisel, has developed a new technology for the precise detection of RNA using DNA-cutting Cas12 nucleases. CRISPR-Cas systems, defense systems in bacteria, have become a plentiful source of technologies for molecular diagnostics.

For the first time, the recovery of unique geological samples combined with sophisticated modelling provides surprising insights into when and where today's Antarctic ice sheet formed. In recent years global warming has left its mark on the Antarctic ice sheets. The "eternal" ice in Antarctica is melting faster than previously assumed, particularly in West Antarctica more than East Antarctica.

Researchers investigate the strong interaction of cholera toxin with a key ganglioside on the surface of intestinal cells Cholera infections caused by Vibrio cholerae bacteria can be life-threatening and the trigger is the cholera toxin produced by the bacteria. It binds to the surface of intestinal cells - more precisely, to certain "sugar lipids" (GM1 gangliosides, GM1) on the cell surfaces.

There are currently around 1.8 million people living with dementia in Germany. Due to increased life expectancy, the proportion will continue to grow: based on data from the Federal Statistical Office, experts expect up to two million cases in 2033. For the first time, an intervention study was carried out to prevent mental decline in older GP patients.

This new concept could allow the needs of previously separate industries to be combined. A research team from the University Alliance Ruhr, Germany, has found a catalyst that can be used to convert ammonia into the energy carrier hydrogen and the fertilizer precursor nitrite. The production of hydrogen and the production of fertilizer have so far been separate chemical processes.

Artificial intelligence can detect lies much better than humans. This also has an impact on social interaction, as a recently published study shows. Humans are bad at recognizing lies. As studies consistently demonstrate, their judgments are barely better than chance. This inability could be one of the reasons why most people refrain from accusing others of dishonesty.

International team of evolutionary biologists investigate genomic underpinnings for the adaptive potential of spoonworts Plant cold specialists like the spoonworts have adapted well to the cold climates of the Ice Ages. As cold and warm periods alternated, they developed a number of species that also resulted in a proliferation of the genome.

New study on user perception of data collection purposes highlights a lack of clarity in privacy notices The European Union and the United Kingdom mandate via the General Data Protection Regulation (GDPR) that users of web services must give their informed consent for their data to be collected and used.

With 8200 solar masses, the black hole fills the evolutionary gap between stellar and supermassive black holes Newly identified fast-moving stars in the star cluster Omega Centauri provide solid evidence for a central black hole in the cluster. With at least 8200 solar masses, it is the best candidate for a class of black holes astronomers have long believed to exist: intermediate-mass black holes, formed in the early stages of galaxy evolution.

Researchers have developed the first cell-free system in which genetic information and metabolism work together Metabolic processes outside living cells only continue as long as they are supplied with building blocks from the outside. A team of Max Planck researchers led by Tobias Erb has now developed the first in vitro system inspired by nature that couples genetics and metabolism and can drive itself.

The usual sites where vascular bulges form are predestined for this from the outset, even in healthy people. This is shown by a study conducted by the Bochum and Bonn medical departments. If a vascular aneurysm bursts in the aorta, it poses an acute danger to life. These so-called aortic aneurysms typically form in the same places on the large blood vessel: either on the upper arch or in the abdominal cavity.

New research by the University Hospital Bonn (UKB) in cooperation with the University of Bonn has shown for the first time that certain early changes in patients with age-related macular degeneration (AMD) can lead to a measurable local loss of vision. This discovery could help to improve the treatment and monitoring of this eye disease in older patients, which otherwise slowly leads to central blindness, and to test new therapies.

Innovative research approach enables the development of new materials and applications in technology and medicine. Researchers at Humboldt-Universität zu Berlin, led Nicola Pinna, have made a groundbreaking advancement in nanotechnology, successfully extending the well-known Stöber method to synthesize amorphous metal-organic frameworks (MOFs) and coordination polymers (CPs).

Investigations with participation by Heidelberg scientists show that later emerging small bodies brought water to the Earth Age data for certain classes of meteorite have made it possible to gain new findings on the origin of small water-rich astronomical bodies in the early solar system. These so-called planetesimals continually supplied building materials for planets - also for the Earth, whose original material contained little water.

Female mammals - including humans - are born with all'of their egg cells. Of a woman's one to two million egg cells, about 400 mature before menopause and can be fertilized. Some egg cells therefore survive for several decades - and need to remain functional over this long time. Extremely long-lived proteins in the ovary seem to play an important role in this, as teams of researchers from Göttingen have now discovered in experiments with mice.

Freiburg-Prague research collaboration achieves scientific breakthrough in understanding cell division.

An international team of researchers has investigated the mechanism that makes some types of bacteria reflect light without using pigments. The researchers were interested in the genes responsible and discovered important ecological connections. These findings were published in the current issue of the renowned journal Proceedings of the National Academy of Sciences (PNAS).
