Graz researchers identify biomarker for cardiovascular diseases
The role of the enzyme dipeptidyl peptidase 3 in the blood pressure-regulating renin-angiotensin system was investigated in the inter-university cooperation project BioTechMed-Graz. The results could pave the way for new therapies for cardio-renal diseases. The renin-angiotensin system (RAS) becomes active at low blood pressure and forms angiotensin II, a hormone that causes blood vessels to constrict, causing blood pressure to rise again.

Microbial space travel on a molecular scale
How extremophilic bacteria survive in space for one year Galactic cosmic and solar UV radiation, extreme vacuum, temperature fluctuations: how can microbes exposed to these challenges in space survive? An international team around Space Biochemistry group at the University of Vienna investigated how the space-surviving microbes could physically survive the transfer from one celestial body to another.

New cancer diagnostics: A glimpse into the tumor in 3D
In order to analyze tumors, they have to be cut into thin slices. Now, a new technology has been developed that makes pieces of the tumor visible in 3D without cutting them. After cancer surgery, the crucial question is: Are there possibly cancer cells left behind that can continue to grow, or has the entire tumor actually been removed? To find out, the tumor is examined by pathologists.

Big-hearted corvids
Taking a look at generosity within the crow family reveals parallels with human evolution. Working together to raise offspring and increased tolerance towards group members contribute to the emergence of generous behavior among ravens, crows, magpies and company - similarly as it did for our human ancestors.

New Deep Learning Models: Fewer Neurons, More Intelligence
Artificial intelligence (AI) can become more efficient and reliable if it is made to mimic biological models. New approaches in AI research are hugely successful in experiments. Artificial intelligence has arrived in our everyday lives-from search engines to self-driving cars. This has to do with the enormous computing power that has become available in recent years.

Autophagy: the beginning of the end
Scientists reveal key steps in the formation of the recycling cen-ters of the cell Autophagy, from the Greek for 'self-eating', is an essential process that isolates and recycles cellular components under conditions of stress or when resources are limited. Cargoes such as misfolded proteins or damaged organelles are captured in a double membrane-bound com-partment called the autophagosome and targeted for degradation.

Between shark and ray: The evolutionary advantage of the sea angels
Threatened with extinction despite perfect adaptation Angel sharks are sharks, but with their peculiarly flat body they rather resemble rays. An international research team led by Faviel A. López-Romero and Jürgen Kriwet of the Institute of Palaeontology has now investigated the origin of this body shape.

Microbial interactions stabilize carbon in the soil
Soils play a major role when it comes to the long-term storage of CO2 and the resulting reduction of this gas in the atmosphere - therefore they can contribute to slowing down climate change. In order to gain a better understanding of these mechanisms, it can be helpful to look at the microscopic level of soil microorganisms.

Cellular stress causes cancer cell chemoresistance
Postgenomic technologies reveal new mechanism of stress-induced chemoresistance Resistance of cancer cells against therapeutic agents is a major cause of treatment failure, especially in recurrent diseases. An international team around the biochemists Robert Ahrends from the University of Vienna and Jan Medenbach from the University of Regensburg identified a novel mechanism of chemoresistance which has now been published in "Nature Communications".

Taking a deep look into animals
Advances in neuroscience research and microscopy: Researchers look deep into organs and nervous systems of animals, ranging from squids and worms to fish and salamanders. Analyses of individual cells in the context of whole organs or tissues is becoming increasingly important in biology. A standard approach so far was to cut larger tissues into thin layers, study each of these sections, and then piece the information again together into a 3D model.

The evolutionary puzzle of the mammalian ear
How could the tiny, tightly connected parts of the ear adapt independently to the amazingly diverse functional and environmental regimes encountered in mammals? A group of researchers from the University of Vienna and the Konrad Lorenz Institute for Evolution and Cognition Research proposed a new explanation for this evolutionary puzzle.

Novel Electric Impulses Relieve the Pain
Stimulating the vagus nerve in the ear can help relieving chronic pain. TU Wien and MedUni Vienna have developed novel, sophisticated methods for electric stimulation of the vagus nerve. The vagus nerve plays an important role in our body. It consists of various fibres, some of which connect to the internal organs, but the vagus nerve can also be found in the ear.

Breaking down stubborn cellulose in time lapse
Researchers at TU Graz in Austria have for the first time ever succeeded in visualizing at the single-molecule level the processes involved in a biological nanomachine, known as the cellulosome, as it degrades crystalline cellulose. The fundamental insights thus obtained could support sustainable concepts of cellulose utilization to make a breakthrough in industrial biotechnology.

How to Put Neurons into Cages
Using microscopically fine 3D printing technologies from TU Wien (Vienna) and sound waves used as tweezers at Stanford University (California), tiny networks of neurons have been created. Microscopically small cages can be produced at TU Wien (Vienna). Their grid openings are only a few micrometers in size, making them ideal for holding cells and allowing living tissue to grow in a very specific shape.
