Identifying compound classes through machine learning
Identifying compound classes through machine learning
Bioinformaticians at the University of Jena develop new method for analysing metabolites Everything that lives has metabolites, produces metabolites and consumes metabolites. These molecules arise as intermediate and end products from chemical processes in an organism's metabolism. Therefore, they not only have huge significance for our lives, but they also provide valuable information about the condition of a living being or an environment.

Stammbaum der Milchstraße
Galaxies like the Milky Way formed by the merging of smaller progenitor galaxies. An international team of astrophysicists led by Dr Diederik Kruijssen from the Centre for Astronomy at Heidelberg University has succeeded in reconstructing the merger history of our home galaxy, creating a complete family tree.

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
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.

Novel glass materials made from organic and inorganic components
Research team from Jena and Cambridge develops glass materials with novel combinations of properties Linkages between organic and inorganic materials are a common phenomenon in nature, e.g., in the construction of bones and skeletal structures. They often enable combinations of properties that could not be achieved with just one type of material.

Duration of solar system formation identified
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).

Infection by parasites disturbs flight behaviour in shoals of fish
Infection by parasites disturbs flight behaviour in shoals of fish
In order to escape predators, many fish - including insects, fish and birds - have developed strategies for rapidly transmitting information on threats to others of their species. This information is transmitted within a group of hundreds, or even thousands, of individuals in (escape) waves. This collective response is also, in the case of fish, known as shoal behaviour.

More plant diversity, less pesticides
More plant diversity, less pesticides
Species-rich plant communities help to naturally reduce herbivore impacts Increasing plant diversity enhances the natural control of insect herbivory in grasslands. Species-rich plant communities support natural predators and simultaneously provide less valuable food for herbivores. This was found by a team of researchers led by the German Centre for Integrative Biodiversity Research Halle-Jena-Leipzig (iDiv), who conducted two analogous experiments in Germany and the USA.

Towards Ultra-High-Resolution Displays
Future display technologies such as virtual and augmented reality require higher pixel resolutions and optical contrast. However, the potential of state-of-the-art displays is limited by the individual pixel size to achieve necessary resolution. Researchers at the University of Stuttgart have now succeeded to observe switching processes at previously unattained nanometer resolution.
