New insights into quantum phenomena at phase transitions - In the past, quantum phenomena could be investigated only in the realm of just a few atoms. A research team from the Technical University of Munich (TUM) and the Technical University of Dresden (TUD) has now discovered conditions for which quantum entanglement dominates on much larger scales.

University of Freiburg study on vocabulary acquisition uses novel game-based design. Freiburg, Sep 29, 2022 If elementary school children are accustomed to many regional and foreign accents because they hear them frequently in their linguistic environment, then it is easier for them to learn new words from other children who speak with unfamiliar accents.

New insights into tumour biology
New insights into tumour biology
The ancient Egyptians, as described in the Ebers Papyrus, already knew that palpation -feeling for hardened lumps - can help diagnose breast cancer. Palpation is still an important element in early screening for breast cancer. On the other hand, measurements on individual cancer cells show that they are softer than the healthy epithelial cells from which they stem, which probably makes them better able to metastasise in dense human tissue.

To be heavy or not - that is the question
To be heavy or not - that is the question
Researchers at the University of Bonn study the way of life of extinct amphibians If you need to lurk at the bottom of a water body waiting for prey, it is wise to stay motionless without resisting against the buoyant forces of water. To do so you need a kind of diving belt that helps to sink. One large amphibian species Metoposaurus krasiejowensis, that lived more than 200 million years ago, compensated for buoyancy with a heavy shoulder girdle.

How contrast agents disperse inside cells
Detailed images of cells with X-ray contrast agents Contrast agents are often used to improve the imaging of soft tissue in micro-computed tomography (microCT). Now a research team led by the Technical University of Munich (TUM) has investigated how these agents disperse inside cells. Their findings could improve the assessment and further development of contrast agents and might contribute to future medical diagnostics.

Wind music causes less transmission than singing
Playing wind instruments spreads more viruses than breathing, but less than speaking or singing A relatively large number of viruses can emerge from the clarinet. It releases considerably more aerosols, which can contain pathogens such as Sars-CoV-2, compared to other instruments such as the flute. However, the risk of transmission from an infected person playing a wind instrument is generally much lower than for people who sing or speak, provided that one spends the same amount of time in their vicinity.

Birth of a sibling triggers long-lasting stress in young bonobos
First-of-its-kind study identifies physiological changes in the transition to siblinghood In any family, the birth of a child is a transformative event, often greeted with positive feelings from parents-and mixed feelings from siblings. The arrival of a new brother or sister, and the loss of parental attention that comes with it, is stressful for any first-born child.

Germany’s oldest beer scientifically considered
Study reveals molecular profile of 19th century beer sample After almost 140 years, researchers at the Technical University of Munich (TUM) opened a lager beer that had been kept at room temperature throughout to analyze it. The beer, dating back to 1885, has now been characterized sensorially and analytically.

Early modern humans in Africa used high-tech adhesives extracted from a local conifer
The second option is more difficult and time consuming. In it, the leaves have to be heated in a kind of underground distillery for several hours, so that the tar drips into a container. It is not known which method was used. Either way, says Schmidt, it was astonishing that early modern humans at that time did not use any plants other than yellowwoods as sources of glue.

What the ’prey’ of a peregrine falcon tells us about the beginnings of our solar system
An international research team led by Tomoki Nakamura (Tohoku, Japan) has studied soil samples collected by the Japanese spacecraft Hayabusa-2 on the asteroid Ryugu. Falko Langenhorst of Friedrich Schiller University in Jena, Germany, was part of the group that gained insights into the formation of the asteroid and the unique processes that took place during the first five million years after the birth of our solar system from the analysis of the extraterrestrial material.

Show me your brain scan and I’ll tell you how old you really are
Electronic comparison of MRI images opens up new possibilities for early detection of diseases The biological age of a person can be accurately determined from brain images using the latest AI technology, so-called artificial neural networks. Until now, however, it was unclear which features these networks used to infer age.

Gas bubble swirls around the heart of the Milky Way
Gas bubble swirls around the heart of the Milky Way
Researchers discover a hot spot near the Sagittarius A* black hole with the Alma radio telescope. There is a black hole in the center of our Milky Way. In the immediate vicinity of this mass monster called Sagittarius A*, things are turbulent. Now, an international group led by Maciek Wielgus of the Max Planck Institute for Radio Astronomy in Bonn has discovered an object that orbits the black hole on a very narrow path in only about 70 minutes.

Zebrafish change their sex in warm water
Research team led by Göttingen University identify DNA -hotspots- that tell zebrafish to change sex in warmer waters. Environment leaves its mark on genome through DNA methylation. In many species, such as zebrafish, sex is partly or completely determined by the environment. Genes can predispose to a particular sex but may be -overruled- by the influence of the environment, for example temperature or population density.

Flow velocity in the gut regulates nutrient absorption and bacterial growth More than a gut feeling The flow velocity in our digestive system directly determines how well nutrients are absorbed by the intestine and how many bacteria live inside it. This is the result of a new study by researchers from the Technical University of Munich (TUM) and the Max Planck Institute for Dynamics and Self-Organization (MPI-DS).

3D printing drones work like bees to build and repair structures Additive manufacturing in-flight An international team of researchers have created a fleet of bee-inspired flying 3D printers for building and repairing structures in-flight. The technology could ultimately be used for manufacturing and building in difficult-to-access or dangerous locations such as tall buildings or help with post-disaster relief construction, say the researchers.

Study shows effect on amygdala in temporal lobe The bacterial toxin botulinum toxin (BTX) - colloquially known as Botox - is probably known to most people as a remedy for wrinkles. But botulinum toxin can do even more: if it is injected into the forehead, for example, it can alleviate depression.

Improved air quality accelerates global warming in recent decades
An international research team led by Leipzig University has used satellite data to demonstrate that concentrations of pollutant particles have decreased significantly since the year 2000. This is necessary due to their impact on health. But it is also of great significance for another reason, since it has reduced the particles- cooling effect on the climate.

Chiral oxide catalysts align electron spin
Controlling the spin of electrons opens up future scenarios for applications in spin-based electronics (spintronics), for example in data processing. It also presents new opportunities for controlling the selectivity and efficiency of chemical reactions. Researchers recently presented first successes with the example of water splitting for producing "green" hydrogen and oxygen.
