Scientists from Heidelberg University investigate which factors determine the stability of ice masses in East Antarctica. As temperatures rise due to climate change, the melting of polar ice sheets is accelerating. An international team of researchers led by geoscientist Dr Kim Jakob from Heidelberg University has now examined the dynamics of the East Antarctic Ice Sheet more closely.

Near the centre of the Milky Way there exists a heretofore unknown population of stars that exhibits characteristic properties. It was discovered by an international research team under the direction of Dr Manuel Arca Sedda of Collaborative Research Centre "The Milky Way System" (CRC 881) of Heidelberg University. The scientists identified as the origin of these stars a globular cluster that made its way into the centre of our home Galaxy a long time ago.

How epithelial cells ward off viruses
The cytosolic sensor NLRP1 identifies viruses as non-self and triggers inflammatory responses The ability to differentiate between self and potentially harmful non-self is vital for the integrity and survival of organisms. In most organisms, the so-called innate immune system is responsible for the recognition of such intruders.

Borexino detector succeeds in measuring the sun's CNO fusion cycle The Borexino Experiment research team has succeeded in detecting neutrinos from the sun's second fusion process, the Carbon Nitrogen Oxygen cycle (CNO cycle) for the first time. This means that all of the theoretical predictions on how energy is generated within the sun have now also been experimentally verified.

Detecting bacteria with fluorescent nanosensors
Luminous carbon nanotubes detect pathogens - and are quick and easy to use. Researchers from Bochum, Göttingen, Duisburg and Cologne have developed a new method for detecting bacteria and infections. They use fluorescent nanosensors to track down pathogens faster and more easily than with established methods.

Analysing Plant Cells With 3D Images
A new image processing programme makes it possible to view and analyse plant cells in detail in 3D. Bioscientists and computer scientists at Heidelberg University helped to develop the open-source software called PlantSeg. It is based on methods of machine learning and can be used to study the process of morphogenesis - how the shape of plants develops - at the cellular level.

The smell of cooperation
Research team with the University of Göttingen finds effect of odour on helpfulness in rats Despite their reputation, rats are surprisingly sociable and actually regularly help each other out with tasks. Researchers at the Universities of Göttingen, Bern and St Andrews have now shown that a rat just has to smell the scent of another rat that is engaged in helpful behaviour to increase his or her own helpfulness.

Controlling fully integrated nanodiamonds
Using modern nanotechnology, it is possible nowadays to produce structures which have a feature sizes of just a few nanometres. This world of the most minute particles - also known as quantum systems - makes possible a wide range of technological applications, in fields which include magnetic field sensing, information processing, secure communication or ultra-precise time keeping.

Ultrathin nanomesh sensor to measure sense of touch
World's first fingertip-mounted sensor that maintains user's sensitivity Scientists from the Technical University of Munich (TUM) and the University of Tokyo have developed an ultrathin pressure sensor that can be attached directly to the skin. It can measure how fingers interact with objects to produce valuable data for technological or medical applications.

Early Christian fish: excavations provide insights into church construction
Early Christian fish: excavations provide insights into church construction
Archaeologists of the University of Münster have uncovered an early Christian basilica in south-eastern Turkey. The team of researchers led by Prof. Engelbert Winter spent eight weeks exposing richly ornamented mosaics with images of fish as well as painted marble reliefs. "These finds cast a new light on the development of church building in the Near East between the 4th and 7th centuries AD," explains Engelbert Winter, professor at the Minor Research Centre in the Department of Ancient History at the University of Münster.

Surprises in 'active' aging
Surprises in ’active’ aging
Physicists from the University of Göttingen use computer simulation to investigate aging in living glassy systems Aging is a process that affects not only living beings. Many materials, like plastics and glasses, also age - ie they change slowly over time as their particles try to pack better - and there are already computer models to describe this.

Novel deep learning method enables clinic-ready automated screening for diabetes-related eye disease Researchers created a novel deep learning method that makes automated screenings for eye diseases such as diabetic retinopathy more efficient. Reducing the amount of expensive annotated image data that is required for the training of the algorithm, the method is attractive for clinics.

An epigenetic ageing clock in trees
An epigenetic ageing clock in trees
Research on environmental history: 330-year-old poplar tree tells of its life Similar to genetic mutations, epigenetic changes, i.e. gene modifications that do not occur on the primary DNA sequence, sometimes arise accidentally in plants and can be transmitted across generations. Using trees as a model, researchers have now shown for the first time that these so-called epimutations accumulate continuously throughout plant development, and that they can be employed as a molecular clock to estimate the age of a tree.

Metal-organic frameworks become flexible
Combined efforts of experiment and simulation pave the way to new applications Materials consisting of inorganic and organic components can combine the best of two worlds: under certain circumstances, the so-called MOFs - short for metal-organic frameworks - are structured in the same order as crystals and are at the same time porous and deformable.

Duration of solar system formation identified
This is an artist's impression of a young star surrounded by a protoplanetary disc in which planets are forming. Using ALMA's 15-kilometre baseline astronomers were able to make the first detailed image of a protoplanetary disc, which revealed the complex structure of the disc. Concentric rings of gas, with gaps indicating planet formation, are visible in this artist's impression and were predicted by computer simulations.

How nitrogen is transferred by a catalyst
Chemists at the University of Göttingen and Goethe University Frankfurt characterise key compound for catalytic nitrogen atom transfer Catalysts with a metal-nitrogen bond can transfer nitrogen to organic molecules. In this process short-lived molecular species are formed, whose properties critically determine the course of the reaction and product formation.

PM 98/2020 201111 How Molecular Chaperones Dissolve Protein Aggregates Linked To Parkinson’s Disease
In many neurodegenerative diseases like Parkinson's, protein aggregates form in the brain and are assumed to contribute to neuronal cell death. Yet there exists a cellular defence mechanism that counteracts these aggregates, known as amyloid fibrils, and can even dissolve fibrils already formed. This defence mechanism is based on the activity of molecular chaperones, i.e. protein folding helpers, of the heat shock protein 70 family (Hsp70).
