Black hole found hiding in star cluster outside our galaxy
Black hole found hiding in star cluster outside our galaxy
International research team of astronomers including Göttingen University use "dynamical method" to discover small black hole Using the European Southern Observatory's Very Large Telescope (ESO's VLT), astronomers including the University of Göttingen have discovered a small black hole outside the Milky Way by looking at how it influences the motion of a nearby star.

COVID-19 leads to a decrease in prosocial behaviour among disadvantaged adolescents
If a family member falls ill with COVID-19, this has a particularly negative effect on young people from an economically disadvantaged and less educated background. These adolescents not only fall behind in school, their non-cognitive abilities also suffer: they are less prosocial than before. This means that they behave less generously, altruistically, and cooperatively.

’Tug of war’ between cells - When crucial connections are missing
Research team led by University of Göttingen investigates the importance of "tight junctions" for cell movement The ability of cells to move together in harmony is crucial for numerous biological processes in our body, for example wound healing, or the healthy development of an organism. This movement is made possible by the connections between individual cells.

Pathomechanisms in heart disease discovered
Pathomechanisms in heart disease discovered
Titin is a "titanically large" protein - the largest in the human body - which enables elastic movements of our muscles, including the heart. Mutations in the titin gene ( TTN ) that impair this function are the most frequent cause of a heart muscle disease known as dilated cardiomyopathy (DCM), which is characterized by a weak pump function.

Researchers detect a diffusion barrier inside fly brain
Researchers detect a diffusion barrier inside fly brain
The neurons, located in the brain are interconnected in a complex pattern and establish special communication points, the synapses. All neurons require a constant environment in order to function reliably. To ensure this, the brain is surrounded by the so-called blood-brain barrier. It ensures, for example, that the nutrient balance always remains the same and that harmful influences do not reach the neurons.

Winter important for cereal yield
Winter important for cereal yield
Weather conditions outside growing season very important The weather conditions in the winter and during the transitional phases from fall to winter and winter to spring have a significant influence on the yield level of key cereal crops, such as winter barley and winter wheat. These were the findings of a research team of scientists at the Chair of Plant Nutrition at the Technical University of Munich (TUM).

Aquatic plant's genome reveals evolutionary surprises
Aquatic plant’s genome reveals evolutionary surprises
International research team including Göttingen University sequence whole genome of quillwort The quillwort is an aquatic plant belonging to an ancient lineage of vascular plants, meaning plants that have tissues to transport water, sap and nutrients. This lineage diverged from the other vascular plants more than 400 million years ago.

Where the wild bears are
New software predicts the movements of large land animals New software helps determine the movements of large wild animals thereby minimising conflicts with people. The software is simpler than measurements obtained using radio transmitters and can be used where conventional methods fail. An international team led by the German Centre for Integrative Biodiversity Research (iDiv), the Friedrich Schiller University Jena, Aarhus University and the University of Oxford has published a description of the new software in the journal Methods in Ecology and Evolution .

Not yet silent spring: shifting sounds of birdsong
Not yet silent spring: shifting sounds of birdsong
Researchers including Göttingen University use citizen science to study birdsong over last 25 years Natural sounds, and birdsong in particular, play a key role in building and maintaining our connection with nature. Birds have been declining due to changing land use and climate change. But how has this affected the dawn chorus around us?

Late bombardment of the Moon revealed
Late bombardment of the Moon revealed
Planetologists from Münster investigate origin of heavy bombardment of the Moon 3.9 billion years ago / Publication in "Science Advances" The lunar surface is covered by numerous craters that date back to the impacts of asteroids. Age determinations on lunar rocks formed during these impacts show a surprising clustering at ages of about 3.9 billion years before present, or about 500 million years after the Moon was formed.

Team of archaeologists finds monumental antique temple: Münster researchers investigate a previously unknown sanctuary from the Roman era
Team of archaeologists finds monumental antique temple: Münster researchers investigate a previously unknown sanctuary from the Roman era
Last summer, archaeologists from the University of Münster discovered a previously unknown sanctuary from the Roman era during excavation work in the ancient town of Doliche in south-eastern Turkey. Over a period of nine weeks, the team - headed by Prof. Engelbert Winter and Prof. Michael Blömer from the Asia Minor Research Centre -uncovered parts of a large temple notable not only for its size but also for its unusual form.

Can we cope without rare-earth elements?
Researchers look for materials for the future A mobile phone is full of raw materials: its electronic components contain valuable precious metals, such as gold, silver and platinum, rare metals, like cobalt, gallium or indium, and rare-earth elements, such as neodymium. Often, the old devices end up in the bin - and, with them, their precious cargo.

New X-ray technology first used with patients
Dark-field X-ray technology improves diagnosis of pulmonary ailments For the first time, researchers at the Technical University of Munich (TUM) have successfully used a new X-ray method for respiratory diagnostics with patients. Dark-field X-rays visualize early changes in the alveolar structure caused by the lung disease COPD and require only one fiftieth of the radiation dose typically applied in X-ray computed tomography.

Insect digestive enzyme activates sugar-containing plant defence substance: Removing the sugar component changes the food plant chosen by cockchafer larvae
Insect digestive enzyme activates sugar-containing plant defence substance: Removing the sugar component changes the food plant chosen by cockchafer larvae
Plants are not entirely at the mercy of their herbivore enemies. Often, chemical defences ensure that the plants are inedible, or even toxic, and as a result insects and other hungry animals steer clear of them. A new study has shown, for the first time, that the degradation of plants' defence substances by insects' digestive enzymes can influence the insects' preference for certain food plants.

’Feeling’ the living cell’s life cycle using optical tweezers
Göttingen researchers use laser to reveal that the inside of living cells softens and fluidifies when dividing Living cells are the basic building blocks of all organisms. We, as humans, are essentially a collection of trillions of living cells: and all these cells emerge from a single fertilized egg.

Help for the weakened heart
Help for the weakened heart
MHH research team demonstrates how inflammatory cells improve the function of diseased heart muscle cells Heart failure or cardiac insufficiency is one of the most common causes of death in Germany and is caused by heart attacks, high blood pressure or heart valve defects. The heart is then no longer able to pump a sufficient amount of blood through the body and supply organs, muscles or other tissues with enough oxygen and nutrients.
