Spintronics: significant progress
An international research team has achieved a breakthrough in atomically thin antiferromagnetic tunnel junctions. This shows the great potential of antiferromagnetic materials for storage technology. Spintronics (spin electronics) deals with the use of electron spin in electronic devices. In contrast to conventional electronics, which only uses the charge of the electrons, spintronics also uses the spin of the electrons, i.e. a "direction of rotation" at the atomic level, to store and process information.

Hardware architecture for post-quantum cryptography
Integrating post-quantum security algorithms into hardware was previously considered a challenge. A research team at Graz University of Technology has developed standardized hardware with additional security measures. They are not yet a reality, but in the not too distant future, sophisticated, powerful quantum computers will be available.

TU Graz Develops Hardware Architecture for Post-Quantum Cryptography
Integrating post-quantum security algorithms into hardware has long been considered a challenge. But a research team at TU Graz has now developed hardware for NIST post-quantum cryptography standards with additional security measures for this purpose. They are not yet a reality, but in the not-too-distant future, sophisticated, high-performance quantum computers will be available.

Depth perception for drone shots
Help in the search for missing persons: New JKU method enables three-dimensional perception of drone images in real time. This works even with strong occlusion and at long distances. Human visual depth perception, i.e. the ability to perceive objects at different distances, is essentially based on the fact that our eyes see slightly different images in terms of perspective.

A Viral Close-Up
Almost everyone knows about HIV. Fewer people know about its relative, HTLV-1. However, HTLV-1 can cause serious illnesses, including cancer. To develop ways to combat this virus, understanding its structure is essential. Martin Obr and Florian Schur from the Institute of Science and Technology Austria (ISTA) and US colleagues now show the virus in close-up in a new paper, published in Nature Structural & Molecular Biology .

Better MRI Videos Thanks to New Machine Learning Method
Using smartly trained neural networks, researchers at TU Graz have succeeded in generating precise real-time images of the beating heart from just a few MRI measurement data. Other MRI applications can also be accelerated using this procedure. Medical imaging using magnetic resonance imaging (MRI) is very time-consuming since an image has to be compiled from data from many individual measurements.

Northern Adriatic: collapse of predator-prey relationships from the 1950s onwards
Palaeontologists trace the influence of humans using predatory snail boreholes Predatory snails drill holes in the shells of their prey. Using these boreholes, a research team led by palaeontologist Martin Zuschin from the University of Vienna was able to create a time series of predator-prey relationships in the northern Adriatic over the past millennia.

Researchers at TU Graz Improve Small Electric Drives
Thanks to innovations in design, control and production technology, brushless drives for pumps and fan systems work more efficiently and quietly. Users of electrical appliances and the automotive industry do benefit. Small electric motors can be found in many household appliances, tools and computers as well as in modern cars, where they drive auxiliary units such as pumps and fans.

20 years of microplastics research: time to act
Science has provided more than enough evidence to develop a collective and global approach to tackle the proliferation of plastic pollution. This is the conclusion of an international research team including environmental psychologist Sabine Pahl from the University of Vienna. The current Science publication particularly emphasises the urgency of a global agreement to curb plastic pollution.

Bleeding risk underestimated in patients with cancer
In a recent study published in the scientific journal "Blood", researchers from MedUni Vienna show that haemorrhages are more common in cancer patients than previously thought and are associated with a poor prognosis and an increased risk of death. The results emphasise the need to devote more attention to this serious complication in clinical practice and research in the future.

An Unexpected Result: The Mammalian Inner Ear is a Striking Example of Convergent evolution
Mammals with distant evolutionary ties but similar ecological roles evolved comparable inner ear shapes A new study reveals the surprisingly convergent evolution in the inner ear of mammals. An international research team led by Nicole Grunstra from the University of Vienna and Anne Le Maître from the Konrad Lorenz Institute (KLI) for Evolution and Cognition Research (Klosterneuburg) showed that a group of highly divergent mammals known as Afrotheria and distantly related, but ecologically very similar mammals independently evolved similar inner ear shapes.

Sustainable Grain Cultivation with Perennial Wheat
In contrast to annual plants, perennial wheat offers a more diverse microbiome and has a significantly lower impact on soil and environment - as has just been proven by researchers at TU Graz's Institute of Environmental Biotechnology. From an ecological point of view, the cultivation of annual cereal crops is a burden on nature.

The fascinating nanostructures of butterflies
A team of interdisciplinary scientists from Australia and Austria has developed a method to understand how butterflies form their fascinating colors. The research study, which was led by Bodo Wilts, Professor of Materials Physics at the Paris Lodron University of Salzburg, sheds new light on a previously little-understood phenomenon in nature.

Big Algebras: Dictionary of Abstract Math
Abstract algebra and algebraic geometry to connect quantum physics with number theory Several fields of mathematics have developed in total isolation, using their own 'undecipherable' coded languages. In a new study published in PNAS , Tamás Hausel, professor of mathematics at the Institute of Science and Technology Austria (ISTA), presents "big algebras," a two-way mathematical 'dictionary' between symmetry, algebra, and geometry, that could strengthen the connection between the distant worlds of quantum physics and number theory.

The insulator unraveled
Scientists at the TU Wien and the University of Vienna have uncovered the detailed structure of the aluminum oxide surface, a challenge that has baffled researchers for decades. Aluminum oxide (Al2O3), also known as alumina, corundum, sapphire, or ruby, is one of the best insulators used in a wide range of applications: in electronic components, as a support material for catalysts, or as a chemically resistant ceramic, to name a few.

Prostate cancer: New AI model can prevent unnecessary prostate removals
Surgical removal of the prostate to treat prostate cancer is currently determined on the basis of tissue sample analysis (Gleason grading). As this method is invasive and often unreliable, scientists around the world are looking for alternatives. A research team at MedUni Vienna has now developed a new method that can be used to identify those patients for whom surgical treatment is the best option.

Multiple sclerosis: Clear decision criteria for therapy adaptation for the first time
The results of a multicentre study on multiple sclerosis recently published in the journal "Neurology" could significantly improve the treatment of this chronic inflammatory disease. Researchers from the Medical Universities of Innsbruck and Vienna and the Inselspital, University Hospital Bern have shown that two or more lesions in the brain visible on magnetic resonance imaging (MRI) within one year are an indication in favour of intensifying treatment.

Learning to coping with adversity through literature
A study currently published in the top journal The Lancet Public Health looks at suicide prevention from the point of view of transmission, the transferability of suicidal thoughts and actions, but also of hope and coping strategies. Schools are an important setting for this transmission in children and young people.
