’Jurassic Shark’ - shark from the Jurassic period already highly developed
Molecular biology phylogenetic tree provides new insights into cartilaginous fish evolution Cartilaginous fish have changed much more in the course of evolution than previously assumed. Evidence for this thesis was provided by molecular biological data on fossil remains of Protospinax annectans , an already highly evolved shark from the late Jurassic.

New CD Laboratory: Folding Proteins Correctly
When proteins are produced in the pharmaceutical industry, they are often initially misfolded and have to be rearranged. At TU Wien, this is being studied in detail in a new CD laboratory . Certain proteins are among the most important products of the pharmaceutical industry - such as insulin or interferons, which are used to treat diabetes, cancer or viral diseases.

Tyrol names newly discovered mushrooms
A new genus of fungi and a previously unknown species of fungi have been named by Innsbruck mycologists after their place of discovery, Tyrol. Ursula Peintner and Martin Kirchmair from the Institute of Microbiology at the University of Innsbruck have named their new discoveries "Tyroliella" and "Penicillium tirolense".

Stem cell transplantation: Processes for the restoration of the immune system discovered
Medicine & Science In stem cell transplants, which are used for the treatment of leukaemia, the patient's haematopoietic system is eliminated and replaced by haematopoietic cells from donors. Even though the amount of complications occurring in this process is steadily decreasing due to medical progress, the exact mechanisms for the restoration of the immune system in these patients have not yet been conclusively clarified.

How we make our way through crowds
A brain's own GPS helps us navigate by detecting the movements of fellow humans around us . Grid cells not only help us navigate our own paths in a complex environment, but also help us analyze the movements of other people, as scientists from the University of Vienna have now shown for the first time.

Evolution of epigenetics explored for the first time
Medicine & Science Christoph Bock's team at the CeMM Research Center for Molecular Medicine at the Austrian Academy of Sciences and the Institute of Artificial Intelligence of MedUni Vienna established a catalog of DNA methylation across 580 animal species. These data ena-bled a detailed dissection of the evolution of epigenetic regulation and the epigenome.

Tracking down the origin of complex living things
Researchers at the University of Vienna and ETH Zurich cultivate "missing link" microorganism How did the complex living things on earth come into being? This is one of the great unanswered questions in biology. A collaboration between the research groups of Christa Schleper at the University of Vienna and Martin Pilhofer at ETH Zurich has brought the answer one step closer.

What the inner ear of Europasaurus reveals about its life
A long-necked dinosaur from northern Germany was a so-called nest fledger Europasaurus was a long-necked, herbivorous dinosaur on four legs. The dinosaur lived in the late Jurassic period about 154 million years ago on a small island in what is now northern Germany. Researchers from the Universities of Vienna and Greifswald have now examined fossil skull remains of Europasaurus using computer tomography.

Austrian research team identifies new therapeutic target for leukemic cutaneous T-cell lymphoma
Leukemic cutaneous T-cell lymphoma (L-CTCL) is a rare type of skin cancer that presents varied clinical features and symptoms. In a recently published study by the University of Veterinary Medicine Vienna and the Medical Universities of Vienna and Graz, the researchers managed to integrate the genomic data from affected patients with pharmacologic studies.

Alpine bacterial strain adapts to the change of seasons
Scientists have discovered for the first time a bacterium in Lake Gossenköllesee in Tyrol that uses two different mechanisms to obtain energy from light. This could be an adaptation to the very pronounced change of seasons in the Alps. The change of seasons is clearly noticeable in the Alps. Moderate temperatures with a high exposure to light in summer give way to months with great cold and only little sunlight in winter.

Seeing the world through baby eyes
New study shows how babies order visual perceptual impressions While adults sort visual impressions at lightning speed, babies have to learn this first. This ability is important for finding their way in everyday life. Until now, it was unclear whether visual perception in the brains of babies is fundamentally different from that of adults before language acquisition.

Organic cation transporters: study provides insights for the first time
Monoamines are neurotransmitters in the central and peripheral nervous systems and they also transmit signals between cells and the brain. This transmission is followed by their reuptake into the cells by means of transporters. While the specific monoamine transporters have already been well studied, not enough is known about the organic cation transporters, which are high-capacity monoamine transporters.

Biologists rewrite "family history" of fungi You can't choose kinship. This also applies to a special group of fungi that could not be more different: Whether they grow in native forests, live in the guts of insects or are found in trees in the Amazon. Until now, they were not considered to be related to each other because of their different appearance and their dissimilar life strategies.

New approach for the development of cancer therapies
In a recent study, researchers from Joanna Loizou's group from CeMM, the Center for Molecular Medicine of the Austrian Academy of Sciences, and the Medical University of Vienna investigated the POL? enzyme and the role it plays in DNA repair. Inhibiting POL? represents a new approach for developing specific therapies, in particular for patients with BRCA1 mutations.

Previously unknown ability of the autonomic nervous system discovered
The autonomic nervous system is known as the control centre for involuntary bodily processes such as the beating of our hearts and our breathing. The fact that this part of the nervous system also has the ability to spontaneously restore muscle function following a nerve injury was discovered by a research group at MedUni Vienna's Department of Plastic, Reconstructive and Aesthetic Surgery as part of their study recently published in the Journal of Neuroscience.

Paralysis: neurons that restore walking have been identified
In an animal model, a study, led by EPFL Lausanne with the participation of MedUni Vienna's Center for Medical Physics and Biomedical Engineering, has identified a class of neurons that provides the crucial impetus for restoring walking ability after spinal cord injuries resulting in paralysis. This study was recently published in the leading journal "Nature".

Neuronal mechanism involved in the learning of maternal behaviour discovered
Various conditions such as postpartum depression or postpartum psychosis can lead to an alteration in maternal behaviour and disrupt the mother-child bonding process. A research team led by Daniela Pollak from MedUni Vienna's Center for Physiology and Pharmacology has conducted a study in which they were able to identify the neuronal circuits in the brain that are activated during the learning of maternal behaviour.

Profiling of sweet-fatty molecules on cell surfaces.
New method enables measurement of glycolipids; now, for example, the relevance in cancer will be investigated So-called glycolipids, or "sweet-fatty" molecules, are a relatively unknown group among the body's diverse lipids. A method developed by an Austrian team led by chemist Evelyn Rampler of the University of Vienna has now provided deeper insights into the functioning of certain glycolipids, which are located, among other things, on the surfaces of stem cells.

Head and neck cancer: Markers to facilitate better treatment in the future
Malignant tumours in the head and neck region are very heterogeneous and therefore difficult to treat. In addition, the lack of prognostic markers is a significant impediment to personalised treatment. A joint study by MedUni Vienna and the Christian Doppler Laboratory for Applied Metabolomics focused on the development and identification of specific markers to improve risk assessment for patients.

Simulated Brain Model Made to See for the First Time
By Birgit Baustädter Researchers at TU Graz have for the first time reproduced the function of vision on a detailed model of the mouse brain. Until now, brain structures could be modelled, but it was not possible to perform specific functions.
