Alzheimer’s: up to 40% of cases are preventable
Early detection of Alzheimer's disease is critical if patients are to receive timely and appropriate care and potential treatments and preventive measures are to be used to the best possible effect. Scientists have so far identified several important risk factors that may trigger or accelerate dementia.

Researchers in Graz develop technology for precise assessment of the danger of virus variants One of the greatest difficulties in combating viral infectious diseases is the excellent adaptability of the viruses. In the case of SARS-CoV-2, we have seen how quickly new variants are constantly being formed that bring with them different properties.

More Dependability in the Internet of things
Tens of millions of mini-computers now populate our planet - built into everyday objects, among other things. Their reliability is still an issue - one to which TU Graz is dedicated to pursuing. "Smart applications are already an integral part of our everyday lives and are embedded in everyday objects such as mobile phones, smart watches and smart electricity meters.

Nature Inspired Peptide Shows Antitumoral Effect
Nature Inspired Peptide Shows Antitumoral Effect
Researchers at MedUni Vienna, Karl Landsteiner University of Health Sciences, University of Veterinary Medicine Vienna and Ludwig Boltzmann Institute for Cancer Research demonstrate an anti-tumor effect of certain nature-derived cyclic peptides. The study, which has now been published internationally, not only demonstrates the inhibition of cell division by these peptides, but even their ability to cause cell death of cancer cells.

Climate change threatens ice caves in Austria
Climate change threatens ice caves in Austria
Eight ice caves in four Austrian provinces: In a study, a team of geologists from the University of Innsbruck has for the first time comprehensively documented the ice losses and gains in alpine ice caves over the last 2000 years. Geologist Tanguy Racine from the University of Innsbruck warns: Especially the ice of smaller caves threatens to disappear in the near future and with it a valuable climate archive.

Faster friction - less wear
Faster friction - less wear
A seemingly paradoxical effect: friction normally causes more damage at higher speeds. But at extremely high speeds, it is the other way around. When two metal surfaces slide against each other, a variety of complicated phenomena occur that lead to friction and wear: Small crystalline regions, of which metals are typically composed, can be deformed, twisted or broken, or even fuse together.

Information is as valuable to us as objects.
Information is as valuable to us as objects.
Through technical progress, it is now possible to store an almost unlimited amount of information and data. We all make active use of this. In a study published in the journal PNAS, economists and psychologists from the University of Innsbruck and Carnegie Mellon University (USA) show that we are just as attached to information as we are to physical objects.

Tracking in dense forest with commercial drones
Tracking in dense forest with commercial drones
New method enables people and game tracking in dense forest cover with commercially available drones. Back in the spring, JKU reported on the world's first real-time tracking of people in dense forest cover. Now comes the next step . The system can now also be used for normal, commercially available drones.

Recycling Greenhouse Gases
Recycling Greenhouse Gases
CO2 and methane can be turned into valuable products. But until now the catalysts required for such reactions quickly lose their effectiveness. TU Wien has now developed more stable alternatives. Wherever the production of harmful greenhouse gases cannot be prevented, they should be converted into something useful: this approach is called "carbon capture and utilisation".

Miniaturized Lab-on-a-Chip for real-time Chemical Analysis of Liquids
Miniaturized Lab-on-a-Chip for real-time Chemical Analysis of Liquids
A fingertip-sized chip replaces bulky laboratory equipment. An infrared sensor has been developed at TU Wien (Vienna) that analyses the content of liquids within the fraction of a second. In analytical chemistry, it is often necessary to accurately monitor the concentration change of certain substances in liquids on a time scale of seconds.

Neuronal back-up system discovered
Neuronal back-up system discovered
Researchers at MedUni Vienna have discovered that neurons have an emergency back-up system to enable them to remain functional even when their energy supply is disrupted. As in many areas of technology, an emergency back-up serves to compensate for any energy supply failures experienced by neurons. The results of the study have now appeared in the Journal of Neuroscience.

A Perfect Trap for Light
At TU Wien (Vienna) and The Hebrew University of Jerusalem, a "light trap" was developed in which a beam of light prevents itself from escaping. This allows light to be absorbed perfectly. Whether in photosynthesis or in a photovoltaic system: if you want to use light efficiently, you have to absorb it as completely as possible.

New drug expands treatment opportunities for rheumatoid arthritis
In its final Phase III clinical trial, a new drug for treating rheumatoid arthritis has proved to be at least as effective as the current "gold standard" treatment for this autoimmune disease. This opens up new treatment options for affected patients. The results of the international multicentre study led by MedUni Vienna were recently published in the prestigious "New England Journal of Medicine".

New role of immune cells in liver regeneration identified
If liver tissue has to be removed due to cancer or another liver disease, the organ usually regenerates quickly, soon becoming fully functional once again. Medical science has not yet completely understood the complex processes that enable tissue recovery following resection. Now, for the first time, a MedUni Vienna research team has discovered the vital role of immune cells that boost the production of liver cells.

Asian elephants have nasal pronunciation
Asian elephants have nasal pronunciation
Mammalian sounds in general may be more flexible than previously thought Researchers at the University of Vienna used an acoustic camera that can visualize sound pressure to study the sounds made by Asian elephants. The animals utter their low-frequency sounds mostly from the trunk, or simultaneously from the mouth and trunk, and only rarely from the mouth alone.

Caterpillar-like bacteria crawl in our mouths
Evolution of longitudinal division and multicellularity in oral bacteria. To survive in the oral cavity, bacteria have evolved to divide along their longitudinal axis without separating from each other. This is what a research team led by cell biologist Silvia Bulgheresi of the University of Vienna and microbial geneticist Frédéric Veyrier of the Institut national de la recherche scientifique (INRS) recently discovered.

First treatment for liver damage in alpha-1-antitrypsin deficiency
Alpha-1-antitrypsin deficiency is a genetic disorder that often leads to serious damage to the lungs and liver. Although there are already therapeutic measures available for alleviating pulmonary emphysema caused by the missing enzyme, the precise background to the associated liver damage was hitherto unclear and there was no known treatment option.

The electron slow motion: Ion physics on the femtosecond scale
The electron slow motion: Ion physics on the femtosecond scale
When ions penetrate a material, highly complex processes take place - so fast that they could hardly be analyzed until now. But sophisticated measurements have now made it possible. How do different materials react to the impact of ions? This is a question that plays an important role in many areas of research - for example in nuclear fusion research, when the walls of the fusion reactor are bombarded by high-energy ions, but also in semiconductor technology, when semiconductors are bombarded with ion beams to produce tiny structures.

Fish deaths in the Oder: algae toxin detected in Oder water
Fish deaths in the Oder: algae toxin detected in Oder water
Scientists of the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) and the University of Vienna believe that natural causes for the mass development of algae are unlikely. Recent investigations substantiate the suspicion that mass development of a toxic brackish water alga has taken place in the Oder River.
