Immune cells in the starting blocks: 'Always ready' is hard work
Immune cells in the starting blocks: ’Always ready’ is hard work
When pathogens invade the body, the immune system must react immediately and prevent or contain an infection. But how do our immune cells stay ready when there is no attacker in sight? Scientists from Vienna and Salzburg have come up with an intriguing explanation: They are stimulated by healthy tissue.

Nanofibers rid water of hazardous dyes
Nanofibers rid water of hazardous dyes
Dyes, such as those used in the textile industry, are a major environmental problem. At TU Wien, efficient filters have now been developed - based on cellulose waste. Using waste to purify water may sound counterintuitive. But at TU Wien, this is exactly what has now been achieved: a special nanostructure has been developed to filter a widespread class of harmful dyes from water.

Ready and Vigilant: Immune Cells on Standby
Ready and Vigilant: Immune Cells on Standby
When pathogens invade the body, the immune system must react immediately to prevent or contain an infection. But how do our defence cells stay ready when no attacker is in sight? Scientists from Vienna have found a surprising explanation: They are constantly stimulated by healthy tissue. This keeps them active and ready to respond to pathogens.

Liver cancer: Molecular signalling pathway of tumour development decoded
Liver cancer: Molecular signalling pathway of tumour development decoded
As a malignant disease of the liver cells, hepatocellular carcinoma (HCC) is one of the main causes of cancer-related deaths. While the treatment options for this aggressive type of cancer remain limited, the incidence is increasing. A research team led by Latifa Bakiri and Erwin Wagner from MedUni Vienna's Clinical Institute for Laboratory Medicine has now described a molecular signalling pathway that plays a key role in the development of liver cancer, thereby identifying a potential new starting point for the development of therapeutic treatments.

COSINUS searches for dark matter
COSINUS searches for dark matter
In the COSINUS research project, an international team involving TU Wien and the Austrian Academy of Sciences (ÖAW) is searching for evidence of dark matter. The large-scale experiment is now starting in Italy . How can we understand dark matter? It probably makes up around 85% of the mass in the universe, but what it is and what it consists of is still one of the biggest and most difficult questions in modern physics.

How soil microbes survive in harsh desert environments
How soil microbes survive in harsh desert environments
As desertification spreads worldwide, scientists discover how desert microbes endure harsh drought periods Prolonged droughts followed by sudden bursts of rainfall - how do desert soil bacteria manage to survive such harsh conditions? This long-debated question has now been answered by an ERC project led by microbiologist Dagmar Woebken from the Centre for Microbiology and Environmental Systems Science (CeMESS) at the University of Vienna.

New disease gene for epilepsy and developmental disorder discovered
New disease gene for epilepsy and developmental disorder discovered
GABA A receptors play a central role in the development of epilepsy and developmental disorders, with nine out of 19 GABA A receptor genes already associated with genetic diseases. Now, as part of an international study led by Martin Krenn from MedUni Vienna's Department of Neurology, GABRA4 has been identified as a new disease gene in four cases.

Seed ferns: plants experimented with complex leaf vein networks 201 million years ago
Flowering plant-type leaf veins died out and re-evolved several times in the course of the Earth's history According to a research team led by palaeontologists from the University of Vienna, the net-like leaf veining typical for today's flowering plants developed much earlier than previously thought, but died out again several times.

Security Vulnerability in Browser Interface Allows Computer Access via Graphics Card
Security Vulnerability in Browser Interface Allows Computer Access via Graphics Card
Researchers at TU Graz were successful with three different side-channel attacks on graphics cards via the WebGPU browser interface. The attacks were fast enough to succeed during normal surfing behaviour. Modern websites place ever greater demands on the computing power of computers. For this reason, web browsers have also had access to the computing capacities of the graphics card (Graphics Processing Unit or GPU) in addition to the CPU of a computer for a number of years.

Stellar winds of three sun-like stars detected for the first time
Astrophysicists were able to quantify the mass loss of stars via their stellar winds An international research team led by a researcher from the University of Vienna has for the first time directly detected stellar winds from three Sun-like stars by recording the X-ray emission from their astrospheres, and placed constraints on the mass loss rate of the stars via their stellar winds.

Novel UV Broadband Spectrometer Revolutionises Air Pollutant Analysis
Novel UV Broadband Spectrometer Revolutionises Air Pollutant Analysis
The laser-based technology developed at TU Graz enables the continual real-time analysis of air pollutants and their interaction with other gases and sunlight. Sunlight has a major influence on chemical processes. Its high-energy UV radiation in particular is strongly absorbed by all materials and triggers photochemical reactions of the substances present in the air.

Key interaction of molecules discovered to influence hormone release
In a study recently published in the scientific journal PNAS, a research team led by MedUni Vienna has presented results that show a new way for drug development for post-traumatic stress disorder, alongside other indications. Although around four per cent of the population suffer from this mental illness, only symptomatic therapies are currently available.
