Creating order by mechanical deformation in dense active matter
Creating order by mechanical deformation in dense active matter
Researchers at Göttingen University use computer simulation to investigate models of living systems Living or biological systems cannot be easily understood using the standard laws of physics, such as thermodynamics, as scientists would for gases, liquids or solids. Living systems are active, demonstrating fascinating properties such as adapting to their environment or repairing themselves.

Diversity matters
Diversity matters
09/23/2021 The higher the biological diversity in an ecosystem, the better the important processes there function. A heterogeneous environment promotes this effect, while intensive land use weakens it, as a new study shows. Microorganisms, plants, and animals accomplish great feats every day. For example, by decomposing material, producing plant biomass, or pollinating flowers, they keep nature 'up and running,' thereby securing the livelihood of humans.

How Poxviruses Multiply
How Poxviruses Multiply
09/23/2021 Poxviruses have found a unique way of translating their genes into proteins in the infected organism. A team of researchers from Würzburg shows for the first time how the molecular machinery involved works at an atomic level. The last case of smallpox worldwide occurred in Somalia in October 1977.

How robust are ecosystems? Three key indicators hold the clues
How robust are ecosystems? Three key indicators hold the clues
Göttingen University research team involved in global study on conditions and capacity to adapt Ecosystems provide a wide range of services to people. These services depend on basic ecosystem functions, which are shaped by natural conditions like climate, the mix of species and by human intervention.

Insect species survives without sexual reproduction
Insect species survives without sexual reproduction
International researchers including the University of Göttingen demonstrate for the first time that animals can survive very long periods of time without sex It was thought that the survival of animal species over a geologically long period of time without sexual reproduction would be very unlikely, if not impossible.

News on fine cocoa flavor
News on fine cocoa flavor
Quickly and precisely determining the flavor profile of cocoa samples Because a plethora of flavor compounds contribute to the distinctive taste of cocoa, its composition is difficult to analyze. Now, scientists at the Technical University of Munich (TUM) and the Leibniz Institute of Food Systems Biology (LSB) have developed a new methodology that quickly, easily, and precisely quantifies the flavor profile of cocoa samples.

B cells of the immune system discovered in the meninges
A comprehensive analysis of white blood cells in the tissue surrounding the brain / Study published in the journal "Nature Neuroscience" The brain holds numerous unsolved medical mysteries. Only a few years ago it was discovered that the outer layer of the meninges is interlaced with lymphatic vessels.

Local wood with fire protection properties
Local wood with fire protection properties
University of Göttingen and Archroma develop new method for treating wood Forest scientists at the University of Göttingen, together with the Swiss company Archroma, a global specialty chemicals company, have developed a new method for turning affordable and ecologically friendly wood from European forests into high-quality, fire-resistant construction timber.

Molecular Achilles heel of cancer cells discovered
Molecular Achilles heel of cancer cells discovered
Changes in fat metabolism of colorectal cancer cells demonstrated for the first time Where does a malignant tumor obtain the energy to keep growing? That is a key question in cancer research. If the energy source were known, the tumor could be "starved". Researchers have now laid the foundation for this approach: For the first time, they have demonstrated a fundamental difference in the fat metabolism of healthy cells in the inner lining of the intestinal tract and colorectal cancer cells.

Insights into the cellular and molecular changes in male infertility
Insights into the cellular and molecular changes in male infertility
"You can't see the wood for the trees" is a phrase which we certainly don't associate immediately with the medical examination and analysis of testicles. But in a certain way it applies here, too: testicles consist of many different types of cells, and up to now this complex quality prevented these types from being isolated and then analysed.

Hand pollination of crops is of major importance
Hand pollination of crops is of major importance
Research team at the Universities of Göttingen and Hohenheim analyses use in worldwide commercial cultivation Pollinators - such as bees, butterflies and birds - are essential for agricultural production. However, natural pollination can also fail or be insufficient, which can lead to lower yields and poorer quality.

Willingness to take part in demonstrations depends on group size
The size of one's own group motivates protestors more than the number of counter-demonstrators / interdisciplinary study of the Cluster of Excellence ECONtribute: Markets & Public Policy at the Universities of Bonn and Cologne The expected number of participants at a rally is decisive for people's willingness to participate in left-wing or right-wing political protest.

Messengers from gut to brain
Messengers from gut to brain
Seen for the first time: T cells traveling from the gut and skin to the central nervous system Scientists have long been aware of a link between the gut microbiome and the central nervous system (CNS). Until now, however, the immune cells that move from the gut into the CNS and thus the brain had not been identified.

Bypassing side effects: Nanocontainers transport active ingredients directly to their target
Using nanoparticles, a Jena research team implemented the targeted transport of an active ingredient into liver tissue. Using nanoparticles, a Jena research team implemented the targeted transport of an active ingredient into liver tissue. The particles were functionalized with a dye that is specifically absorbed by liver cells, and they carried an inhibitor of the signal protein PI3Kinase ? , which contributes to the development of liver failure in sepsis.

Photosynthesis even at high temperatures: helper protein ensures the formation of chlorophyll
New study reveals the protective function of the chaperone cpSRP43 against heat shock Plants make use of complex metabolic processes to produce chlorophyll - the pigment that gives them their green colour and enables photosynthesis. The fact that so-called chlorophyll biosynthesis works smoothly even in the presence of heat is due to a certain helper protein: the chaperone cpSRP43.

Deadwood in the global carbon cycle
The importance of insects in the decomposition of wood The speed at which deadwood decomposes in forests depends on the climate as well as on fungi and insects. An international research team has now determined the annual contribution made by deadwood to the global carbon cycle and quantified the importance of insects in the decomposition of wood for the first time.

Which potatoes thrive despite insufficient phosphorus?
Göttingen University research team analyses different cultivars of tuber Phosphorus is an essential plant nutrient that is becoming increasingly scarce around the world. This means the fertiliser has to be used as efficiently as possible and any loss of nutrients due to leaching and erosion must be minimised.

Using machine learning to understand complex auctions
New AI algorithm as a tool for economists Using a new machine learning algorithm, a team at the Technical University of Munich (TUM) has succeeded in analyzing complex markets and their equilibrium strategies. Until now, such analyses were limited to very simple auction markets. The new numerical method opens up new possibilities for economic theory and new applications as in wireless spectrum auctions, among others.
