Scientists from the University of Vienna have now designed an unconditionally secure system for shopping in digital settings Have you ever been compelled to enter sensitive payment data on the website of an unknown merchant? Would you be willing to consign your credit card data or passwords to untrustworthy hands? Scientists from the University of Vienna have now designed an unconditionally secure system for shopping in such settings, combining modern cryptographic techniques with the fundamental properties of quantum light.
The research group led by chemist Thomas Magauer has accomplsihed a divergent strategy to synthesize nine complex natural compounds. The developed method requires significantly less time and results in a variety of compounds with different structures and biological properties. Chemical synthesis enables the construction of complex molecules and active drug substances.
When people talk about a stroke, they are usually referring to ischemic stroke, in which an artery in the brain becomes blocked and affected areas of the brain are subsequently no longer supplied with nutrients and oxygen. Cerebral hemorrhage is another form of this medical emergency, in which a blood vessel bursts.
Dogs and humans process body postures similarly in their brains A study by researchers at the University of Vienna and the University of Veterinary Medicine Vienna shows that information from body postures plays a similarly important role for dogs as it does for humans. The results offer new insights into how dogs and humans perceive each other and their environment.
Pediatric cancer: weak points in the immune response against metastases discovered
PLUS: Pediatric Cancer: Vulnerabilities in the Immune Response against Metastases Discovered Scientists led by Nikolaus Fortelny, Paris Lodron University Salzburg, and Sabine Taschner-Mandl, St. Anna Children's Cancer Research, have gained new insights into the cell architecture and cell-cell communication of neuroblastoma metastases in a groundbreaking study.

Researchers at the University of Innsbruck are working intensively on preparations for the Euclid mission of the European Space Agency ESA. The space telescope will be launched on July 1 and is expected to produce the largest 3D map of the universe to date. Scientists hope to learn more about the hitherto unexplored dark matter and dark energy of the universe.
For a long time, osteoarthritis was considered to be the result of wear and tear in advanced age. In the meantime, more and more studies are linking the degradation of articular cartilage to inflammatory and metabolic processes in the joint. In researching these processes, a scientific team led by MedUni Vienna has made significant progress in understanding the disease, which could provide a new starting point for diagnosis and therapy.
The heating and cooling requirements of residential buildings account for around a quarter of total energy consumption worldwide. This is where the BIO-NRG-STORE research project at the Kuchl Campus of the Salzburg University of Applied Sciences comes in. An international team is researching how the use of biogenic materials can achieve a reduction in energy consumption.
Significant progress in small-cell lung cancer research
Small-cell lung cancer is a particularly aggressive type of tumor with a consistently high mortality rate. In recent years, the research of scientists at MedUni Vienna's Department of Thoracic Surgery has significantly contributed to a better understanding and new therapeutic approaches in this malignant disease.

A new speciation atlas helps researchers to get more accurate results and new discoveries. To unveil the previously elusive behavior and stability of complex metal compounds found in aqueous solutions called 'POMs', researchers at the University of Vienna have created a speciation atlas now published in Science Advances .
Newly discovered genetic defect disrupts blood formation and immune system
In the quest to find the origin of the puzzling symptoms in four children, researchers from St. Anna Children's Cancer Research Institute, the CeMM Research Center for Molecular Medicine of the Austrian Academy of Sciences (ÖAW), and the Medical University of Vienna have discovered a completely new disease, linking disorders of blood formation, the immune system, and inflammation.

Socioeconomic background affects people's self-perceptions and associated chances of success People from lower socioeconomic backgrounds consider themselves to be less talented - even when they show the same performance as people from higher socioeconomic backgrounds. This misperception subsequently contributes to their further disadvantage.
In the high altitudes of the European Eastern Alps, the number of detected lightning strikes has doubled in the course of the last 40 years. The reasons for this lie in the consequences of the climate crisis. This has now been shown for the first time by a team of Innsbruck researchers from the Institutes of Earth and Atmospheric Sciences and Statistics in the scientific journal Climate Dynamics .
Since its introduction in 2015, a prediction tool developed by the European Society of Medical Oncology (ESMO) has been providing support worldwide in the assessment of the clinical benefits of new cancer therapies. However, previously available versions proved unsuitable for use with malignant diseases of the blood, such as different types of leukaemias or lymphomas.
The amount of electric lighting at night has been increasing at a rate of almost ten percent annually over the past ten years. And this primarily has an impact on the 4.4 billion people across the world who live in cities. Excessive exposure to light at night not only has the potential to trigger sleep disorders, but has also been found to increase the risk of disease such as obesity, depression, diabetes and cancer.
Scientists from the Universities of Salzburg, Torun (Poland) and Potsdam and the Senckenberg Society for Nature Research demonstrate in their recent study that butterflies in the province of Salzburg are sensitive to climate change and intensified agriculture. The studies appeared in the journal Science of the Total Environment.
High-tech lubricant forms by itself when needed
Lubricants that reduce friction are created precisely where friction is high: At TU Wien, this was achieved with special 2D materials. This is important for space technology . Our bodies have a few things in common with machines: we have moving joints, friction and wear occur, so you need suitable lubricants.

Single-atom vacancies in atomically thin insulators created in ultra-high vacuum Single photons have applications in quantum computation, information networks, and sensors, and these can be emitted by defects in the atomically thin insulator hexagonal boron nitride (hBN). Missing nitrogen atoms have been suggested to be the atomic structure responsible for this activity, but it is difficult to controllably remove them.
Distribution in the Mesozoic from present-day Antarctica to Greenland Paleobotanist Mario Coiro of the Institute of Paleontology at the University of Vienna and colleagues at the University of Montpellier (France) have made an important breakthrough in understanding the origin and geographic distribution of cycads.
A new international study involving the Kepler University Hospital for Neurology in Linz has provided important insights into the optimal timing for starting blood-thinning therapy after stroke in patients* with atrial fibrillation. The results of this ELAN study (Early versus late initiation of direct oral anticoagulants in post-ischemic stroke patients with atrial fibrillation) were published in the renowned journal "New England Journal of Medicine".
