Central metabolic pathway runs "backwards" at high carbon dioxide concentrations A research team from the University of Münster and the Technical University of Munich (TUM) has gained new insights into the citric acid cycle: At very high carbon dioxide concentrations, bacteria can also use this central metabolic pathway "backwards" to build useful compounds from carbon dioxide using the enzyme citrate synthase.
High carbon dioxide concentrations are required to allow the central metabolic pathway to run "backwards" / publication in "Nature" The citric acid cycle is an important metabolic pathway that enables living organisms to generate energy by degrading organic compounds into carbon dioxide (COâ‚‚). The first step in the cycle is usually performed by the enzyme citrate synthase, which builds citrate.
Insect decline is one of the greatest challenges facing our society. As a result of the destruction of many natural habitats, bees, bumblebees, butterflies, beetles and the like find less and less food. As a consequence, they are barely able to fulfil their role as pollinators of wild and cultivated plants.

Genome editing in farm animals Genetically engineered animals provide important insights into the molecular basis of health and disease. Research has focused mainly on genetically modified mice, although other species, such as pigs, are more similar to human physiology. Researchers at the Technical University of Munich (TUM) have now generated chickens and pigs in which target genes in desired organs can be efficiently altered.
Astronomers from the Netherlands, Belgium, Chile, the USA and Germany have imaged the newly discovered exoplanet "YSES 2b" right next to its host star An international research team with the participation of Dr Markus Mugrauer from the Astrophysical Institute of Friedrich Schiller University Jena has succeeded in the direct imaging of a young exoplanet.
A quantum spin liquid is a state of matter in which interacting quantum spins do not align even at lowest temperatures, but remain disordered. Research on this state has been going on for almost 50 years, but whether it really exists has never been proven beyond doubt. An international team led by physicist Prof. Martin Dressel at the University of Stuttgart has now put an end to the dream of a quantum spin liquid for the time being.
Not as dense - New 3D imaging technique allows deep insights into subcellular structures
Using a new microscope and methods from biophysics and biochemistry, scientists from the IRI Life Sciences at Humboldt-Universität and the Max Planck Institute for the Physics of Light succeeded in visualizing the density of the spindle and the surrounding cell interior Left: A new imaging setup allows for correlative fluorescence and quantitative phase imaging.

Research team led by University of Göttingen reconstructs late medieval trade routes digitally The Hanseatic League was a confederation of merchant guilds and market towns in Northwestern and Central Europe, which came to dominate trade in the region for three hundred years. A digital platform has now been built which reveals the long-distance trade routes in Northern Europe between 1350 and 1650.
Is it Possible to Slow Down Age-Related Memory Loss?
A team of researchers from Berlin, Dortmund, and Graz are investigating how the substance spermidine can protect aging brain cells. No 062/2021 from Apr 13, 2021 According to a recent study, age-related memory loss may be preventable. Researchers from Freie Universität Berlin, the NeuroCure Cluster of Excellence, the Leibniz-Institut für Analytische Wissenschaften (ISAS) in Dortmund, and the University of Graz found that the substance spermidine - something that is present in all human cells - can protect the mitochondria found in aging brain cells.

Covid-19: analysis of protein interactions as a route to new drugs a team from the Technical University of Munich (TUM) and the Max Planck Institute of Biochemistry paints a comprehensive picture of the viral infection process. For the first time, the interaction between the coronavirus and a cell is documented at five distinct proteomics levels.
The properties of carbon-based nanomaterials can be altered and engineered through the deliberate introduction of certain structural "imperfections" or defects. The challenge, however, is to control the number and type of these defects. In the case of carbon nanotubes - microscopically small tubular compounds that emit light in the near-infrared - chemists and materials scientists at Heidelberg University led by Jana Zaumseil have now demonstrated a new reaction pathway to enable such defect control.
Researchers at the University of Münster discover how cell contacts are dynamically remodelled during egg development in fruit flies / Study published in "Developmental Cell" Within multicellular organisms, cells build connections with each other forming cell layers that cover the surfaces of tissues and organs and separate structures in the body.
Why physical activity entices you to eat more - and how to fight it Around two thirds of men and half of women in Germany* are overweight, according to statistics collected by the German Obesity Society. Concurrently millions of people want to lose weight. One way to do this is exercising. But what influence does sport have on (direct) eating habits? Scientists at the Technical University of Munich (TUM) and the University of Nebraska (USA) have now investigated this question for the first time.
Research team led by the University of Göttingen discovers crater floor sagging from bowl-shaped volcanic ash layer The almost 15-million-year-old Nördlinger Ries is an asteroid impact crater filled with lake sediments. Its structure is comparable to the craters currently being explored on Mars. In addition to various other deposits on the rim of the basin, the crater fill is mainly formed by stratified clay deposits.
Using AI to Diagnose Neurological Diseases Based on Motor Impairment
New Heidelberg approach: analysing movement patterns through machine learning The way we move says a lot about the state of our brain. While normal motor behaviour points to a healthy brain function, deviations can indicate impairments owing to neurological diseases. The observation and evaluation of movement patterns is therefore part of basic research, and is likewise one of the most important instruments for non-invasive diagnostics in clinical applications.

Small cell lung cancer: scientists identify two new approaches for therapy

Neanderthal Ancestry Identifies Oldest Modern Human Genome
In an article published in Nature Ecology & Evolution , an international team of researchers sequence the genome of an almost complete skull first discovered in ZlatÃoe Kůň, Czechia in the early 1950s and now stored in the National Museum in Prague. The segments of Neanderthal DNA in its genome were longer than those of the Ust-Ishim individual from Siberia, the previous oldest modern human sequenced, suggesting modern humans lived in the heart of Europe more than 45,000 years ago.

Analysis of ancient bones reveals Stone Age diet details
Fish was not on the menu of the hunter-gatherers of southern Europe 27,000 years ago. Surprisingly, people on the Iberian Peninsula in the Late Gravettian period mostly ate plants and land animals such as rabbits, deer and horses. An international team of researchers has been able to determine this for the first time on the basis of an isotope study of human fossils from the Serinyà caves in Catalonia.
