Mathematicians find core mechanism to calculate tipping points Climate change, a pandemic or the coordinated activity of neurons in the brain: In all of these examples, a transition takes place at a certain point from the base state to a new state. Researchers at the Technical University of Munich (TUM) have discovered a universal mathematical structure at these so-called tipping points.

Fundamental regulation mechanism of proteins discovered
Fundamental regulation mechanism of proteins discovered
A research team led by Göttingen University find novel switch in proteins with wide-ranging implications for medical treatments Proteins perform a vast array of functions in the cell of every living organism with critical roles in almost every biological process. Not only do they run our metabolism, manage cellular signaling and are in charge of energy production, as antibodies they are also the frontline workers of our immune system fighting human pathogens like the coronavirus.

'Pokemonas': bacteria closely related to lung parasites discovered and named after Pokémon
’Pokemonas’: bacteria closely related to lung parasites discovered and named after Pokémon
'Pokemonas' live in round amoebae, similar to Pokémon, which are caught inside balls in the popular video game A research team at the University of Cologne has discovered previously undescribed bacteria in amoebae that are related to Legionella and may even cause disease. The researchers from Professor Dr Michael Bonkowski's working group at the Institute of Zoology have named one of the newly discovered bacteria 'Pokemonas' because they live in spherical amoebae, comparable to Pokémon in the video game, which are caught in balls.

Corals That ’Spit’ Algae
Microalgae of the dinoflagellate group are known for their ability to survive in other animal cells. These tiny single-cell organisms have engaged in mutually beneficial relationships with corals since primeval times. By passing on critical nutrients to their hosts, dinoflagellates allow corals to thrive even in barren areas.

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.

Scientists provide new insights into the citric acid cycle
Scientists provide new insights into the citric acid cycle
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 (CO₂). The first step in the cycle is usually performed by the enzyme citrate synthase, which builds citrate.

Chickens and pigs with built-in genetic scissors
Chickens and pigs with built-in genetic scissors
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.

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.

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.

Plants regulate their nitrogen supply with the help of bacteria
Plants enrich soil with flavonoids to attract more nitrogen producing bacteria / Study could lead in the long term to new varieties that need less fertilizer The study was led by the Universities of Bonn and Southwest China. Cologne-based plant researcher Professor Marcel Bucher of CEPLAS, the Cluster of Excellence on Plant Sciences, took part in the study.

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.

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 ZlatĂoe 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 Serinyŕ caves in Catalonia.

A more effective production of therapeutic antibodies
A more effective production of therapeutic antibodies
Immunoglobulins are antibodies that are generated by the immune system in answer to the sudden emergence of macromolecules. For example, these might be on the cell surface of bacteria that have infiltrated the body, or they are found in abnormal somatic cells. These play an important role in the identification and suppression of infections, such as Hepatitis A/B or Rabies, and in controlling cancer cells.

Auto-aggressive immune cells cause fatty liver hepatitis Non-alcoholic steatohepatitis (NASH), often called 'fatty liver hepatitis', can lead to serious liver damage and liver cancer. A team of researchers at the Technical University of Munich (TUM) has discovered that this condition is caused by cells that attack healthy tissue - a phenomenon known as auto-aggression.

How Grasslands respond to climate change
How Grasslands respond to climate change
Effects of CO2 increase were already apparent in the past century The rise in atmospheric carbon dioxide concentration and concurrent climate change has led to yield reductions of grass-rich grassland vegetation in the past century. This observation was made by researchers at the Technical University of Munich (TUM) who, working jointly with colleagues from Rothamsted (U.K.), conducted a study on the world's oldest permanent ecological experiment there.
