View into plant cells: A membrane protein is targeted to two locations
View into plant cells: A membrane protein is targeted to two locations
Metabolic processes are especially complex in plants due to their obligate sessile life style - which is why scientists discover more and more new and surprising connections that occur within their cells. An important metabolic route that has occupied plant scientists for decades is the so-called oxidative pentose-phosphate pathway by which carbohydrates are converted to reduction power.

Protecting the Neuronal Architecture
Protecting nerve cells from losing their characteristic extensions, the dendrites, can reduce brain damage after a stroke. Neurobiologists from Heidelberg University have demonstrated this by means of research on a mouse model. The team, led by Hilmar Bading in cooperation with Junior Professor Dr Daniela Mauceri, is investigating the protection of neuronal architecture to develop new approaches to treating neurodegenerative diseases.

Selectively Reactivating Nerve Cells to Retrieve a Memory
Selectively increasing the levels of a certain protein in nerve cells that play a key role in memory storage boosts memory performance, as demonstrated in experiments on mice by a group of scientists at Heidelberg University led by Dr Ana Oliveira. The responsible protein is Dnmt3a2 - a so-called epigenetic factor that chemically modifies the genome and thus influences memory processes.

Why developing nerve cells can take a wrong turn
Loss of ubiquitin-conjugating enzyme leads to impediment in growth of nerve cells / found between cellular machineries of protein degradation and regulation of the epigenetic landscape in human embryonic stem cells A group of scientists from CECAD, the Cluster of Excellence 'Cellular Stress Responses in Aging-Associated Diseases,' have found a mechanism by which neurodevelopmental diseases concerning neurons can be explained: The loss of a certai

Triggered by light, a novel way to switch on an enzyme: Biotechnology
Triggered by light, a novel way to switch on an enzyme: Biotechnology
Enzymes: they are the central drivers for biochemical metabolic processes in every living cell, enabling reactions to take place efficiently. It is this very ability which allows them to be used as catalysts in biotechnology, for example to create chemical products such as pharmaceutics. A topic that is currently being widely discussed is photoinduced catalysis, in which researchers harness the ability of nature to start biochemical reactions with the aid of light.

High-resolution 3D view inside tumors
High-resolution 3D view inside tumors
Breast cancer is the most common cancer in women. But individual tumors can vary significantly, presenting different spatial patterns within their mass. Researchers at the Technical University of Munich (TUM) and Helmholtz Zentrum München have now succeeded in visualizing spatial changes within tumors by means of optoacoustics.

Should tomatoes go in the fridge?
Should tomatoes go in the fridge?
Research team from the University of Göttingen investigates the influence of storage on the flavour of ripe tomatoes There is much debate about the correct storage of tomatoes. There are two main options available to consumers: storage in the refrigerator or at room temperature. A research team from the University of Göttingen has now investigated whether there are differences in the flavour of ripe tomatoes depending on how they are stored and taking into account the chain of harvesting from farm to fork.

A disease trigger for pancreatitis has been identified
A disease trigger for pancreatitis has been identified
One factor contributing to the development of pancreatitis lies in mutations within a cell membrane ion channel that is characterized by its specific permeability for calcium ions. This groundbreaking discovery was made by a research team at Technical University of Munich (TUM), in cooperation with other groups from Germany, Japan and France.

An Alternative for Antibiotics
International Team of Researchers Investigates Antibacterial Effects of Antimicrobial Peptides No 073/2020 from May 01, 2020 Scientists at Cornell University, Georgetown University, and Freie Universität Berlin have analyzed and summarized to what extent antimicrobial peptides, such as those found in plants and animals, can be used as an alternative to conventional antibiotics.

Preserving inflammation-free phases
Preserving inflammation-free phases
Crohn's disease is a chronic inflammatory disorder of the intestine that, in most cases, relapses episodically. As of now, there is no cure for this disease. A research group led by the Technical University of Munich (TUM) has discovered a marker at a microscopic level, which can be used to identify patients that show a high probability of suffering from an inflammation recurrence in the immediate future.

A new mechanism triggering cell death and inflammation: a left turn that kills
Z-form nucleic acids are double-stranded DNA and RNA molecules with an unusual left-handed double helix structure, as opposed to the classical right-handed Watson-Crick double helix. Z-nucleic acids were discovered more than 40 years ago, but their biological function has remained poorly understood.

Blocking sugar structures on viruses and tumor cells
Blocking sugar structures on viruses and tumor cells
Coronavirus: University operations limited +++ make use of online services +++ many staff working from home +++ www.tum.de/corona Artificial sugar-binding protein may inhibit cell growth During a viral infection, viruses enter the body and multiply in its cells. Viruses often specifically attach themselves to the sugar structures of the host cells, or present characteristic sugar structures on their surface themselves.

Coronavirus: University operations limited +++ make use of online services +++ many staff working from home Biochemical methods and AI show even the finest capillaries Diseases of the brain are often associated with typical vascular changes. Now, scientists at LMU University Hospital Munich, Helmholtz Zentrum München and at the Technical University of Munich (TUM) have come up with a technique for visualising the structures of all the brain's blood vessels - right down to the finest capillaries - including any pathological changes.

First comprehensive map of the proteome of the model plant Arabidopsis thaliana Plants are essential for life on earth. They provide food for essentially all organisms, oxygen for breathing, and they regulate the climate of the planet. Proteins play a key role in controlling all aspects of life including plants.

Why Individuals Are Not Alike
Neurobiologists studied how brain development influences behavioral differences No 051/2020 from Mar 06, 2020 Neurobiologists at Freie Universität Berlin led by Bassem Hassan, Einstein BIH Visiting Fellow, in collaboration with the group led by Robin Hiesinger at the Department of Biology, Chemistry, and Pharmacy at Freie Universität Berlin, described in a study published in Science why fruit flies display individual behavioral differences despite having the same genotype and being reared in identical environmental conditions.

Eat or be eaten
Eat or be eaten
Biodiversity increases the efficiency of energy use in grasslands Plants obtain their energy from the sun. Other beings rely on eating to survive. Yet how does the energy flow inside ecosystems function and are there differences between ecosystems with many species in comparison to those with few species' Researchers have now examined these questions using a holistic approach by evaluating data gathered through a large-scale biodiversity experiment.

Trusting Our Own Knowledge
What do we know about the topic of climate change and how great is our trust in our own knowledge? An interdisciplinary team of researchers from Heidelberg University has explored this question in a representative study involving around 500 participants. It turned out that those interviewed mainly were uncertain of their own level of knowledge when confronted with false statements.

Molecular Motor
How do cells disentangle clumped, and hence non-functional, proteins? A Dutch-German team including researchers from Heidelberg University explored this question. The researchers describe a molecular machine which pulls on exposed loops of the protein chains and extracts them from the protein aggregate.

"A rethinking in the minds of researchers is necessary": Guest comments
The reproducibility of research results is one of the fundamental quality criteria in science. The demand for transparency of the scientific knowledge process aims to ensure the repeatability of scientific studies or experiments. The project "Opening Reproducible Research" (o2r) of the Institute for Geoinformatics of the University of Münster and the University and State Library of Münster deals with this topic.
