New possibilities for controlling signal routing in quantum information processing Routing signals and isolating them against noise and back-reflections are essential in many practical situations in classical communication as well as in quantum processing. In a theory-experimental collaboration, a team led by Andreas Nunnenkamp from the University of Vienna and Ewold Verhagen based at the research institute AMOLF in Amsterdam has achieved unidirectional transport of signals in pairs of "one-way streets".

By Falko Schoklitsch By changes in the wavelength of light pulses in fibre optic cables, researchers at TU Graz can measure where rockfalls, landslides, fires and earthquakes are taking place. Landslides and rockfalls are increasingly becoming a real threat to people and infrastructure in light of the changing climate and the associated changes in soil and rock structure.

Climate change is accompanied by increasing temperatures, which are leading to ever greater challenges in urban areas, both at work and in the home office.

Japanese IT company NEC has built the first quantum processor based on the ParityQC architecture. The Parity technology was invented at the University of Innsbruck and is being further developed and marketed by the spin-off ParityQC. NEC is now making the quantum computer, which specializes in optimization problems, available to the scientific community via the cloud.

A study conducted by researchers from the Department of Neurology at MedUni Vienna and University Hospital Vienna has demonstrated for the first time that diagnosis of multiple sclerosis (MS) can be significantly improved by additionally measuring the thickness of retinal layers in the eye. Use of the procedure, which is already available at the Departments of MedUni Vienna and University Hospital Vienna, helps to detect the condition at an earlier stage and predict its progression more accurately.

Inflammations of the peritoneum (peritonitis) are as frequent as they are feared complications in peritoneal dialysis, a form of kidney replacement therapy for independent use at home. The bacteria responsible for the life-threatening infections are becoming increasingly resistant to many antibiotics.

A study with BOKU participation shows that biodiversity in intensive agriculture is not economically profitable for farmers. Measures for more sustainable agriculture can increase the number and diversity of wild bee species in grassland and thus increase pollination and crop yields in neighboring fields.

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.

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.

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 .

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 .
