Small cell lung cancer (SCLC) is a particularly aggressive tumour, which has so far been treated with standardised measures. A study led by MedUni Vienna has shown for the first time that different SCLC subtypes have specific molecular characteristics, which is why those affected respond in different ways to cancer treatment.
More than 5% of all Austrians suffer from depression. However, little is known about the biological basis of this disease. In a new study, scientists led by Alexander Karabatsiakis from the Institute of Psychology at the University of Innsbruck have now observed a strong correlation between the severity of depression and the level of the stress hormone cortisol in hair.
New diagnostic procedure for fish allergy explored
As early as 2018, a research team of the MedUni Vienna showed that strict avoidance of all types of fish is in fact only necessary for few fish-allergy sufferers. However, reliable tests to determine which types could be tolerated and eaten have not been available until now. In their current study, the researchers demonstrate that a new and effective diagnostic procedure.

Researchers at TU Vienna and FHI Berlin succeeded in monitoring a catalytic reaction with three different microscopies under exactly the same conditions in real time. In this way, information is obtained that none of the methods alone could reveal. One has to look very closely to exactly understand what processes take place on the surfaces of catalysts.
For the first time that ticks weaken skin’s immune response
Hitherto, scientists have not fully understood why ticks are such dangerous disease vectors. A research team led by Johanna Strobl and Georg Stary from MedUni Vienna's Department of Dermatology shows that tick saliva inhibits the skin's defence function, thereby increasing the risk of diseases such as tick-borne encephalitis (TBE) or Lyme disease.

New findings on the effects of Covid-19 on the colon
Although SARS-CoV-2 infections mainly attack the lungs, in many cases they can also damage other organs, such as the colon: around 60% of patients experienced digestive tract impacts. Researchers at MedUni Vienna have analysed the manifestations of Covid-19 in the lungs and colon and pinpointed the differences at a molecular level.

Anaplastic large cell lymphoma (ALCL) is an aggressive blood cancer that mainly affects children and adolescents, but it can also affect adults. A recent international study led by scientists from the Medical University Vienna and the Veterinary Medicine Vienna has now identified a new biomarker and effective therapeutic approach with the protein PDGFRβ and its downstream signaling pathway STAT3/5.
A research team led by Matthias Preusser from MedUni Vienna's Division of Oncology had already demonstrated that cancer patients benefit from a third vaccination to protect them against COVID. A recent study now also supports fourth vaccination for this vulnerable group. However, passive immunisation by administering an antibody combination to cancer patients does not seem to provide adequate protection.
An international team of researchers with the participation of Innsbruck geologist Christoph Spötl was able to reconstruct the monsoon of the last millennium in northeastern India in detail for the first time using dripstones. The region with the highest precipitation on earth today once suffered several megadroughts with massive famines.
Designing New Quantum Materials on the Computer
A new design principle can now predict the properties of quantum materials that have hardly been explored so far. For the first time, a strongly correlated topological semimetal has been discovered using a computer. How do you find novel materials with very specific properties - for example, special electronic properties which are needed for quantum computers?

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.
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.
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.
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.
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.
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.
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".
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.
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.
