Using 3D printing technology and ultrasonic joining technique, researchers at TU Graz succeeded in attaining an extremely strong joining of the renewable raw material wood with metal and polymer composite. The renewable raw material wood is climate-neutral and at the same time light and strong, making it fundamentally attractive for use in vehicle manufacturing.

In an analysis of smartphones of ten manufacturers, researchers at TU Graz have found that the Android kernels used are vulnerable to known attacks - so-called one-day exploits - despite existing protection mechanisms. Smartphones are a constant companion and important work tool for many people. In addition to contacts, appointments and emails, the devices are increasingly being used for sensitive tasks such as online banking or official matters.

Many decisions are being made by neural networks. But are they rational and fair? Methods to ensure this are being developed at TU Wien. Many decisions that were previously made by humans will be left to machines in the future. But can we really rely on the decisions made by artificial intelligence? In sensitive areas, people would like a guarantee that the decision is actually sensible, or at least that certain serious errors have been ruled out.

TU Wien (Vienna) has patented a completely new method of dampening vibrations. This is an important step for precision devices such as high-performance astronomical telescopes. When everything shakes, precision is usually impossible - everybody who has ever tried to take a photo with shaky hands or make handwritten notes on a bumpy bus journey knows that.

Better understanding of this natural formation process offers potential for technical developments A new interdisciplinary study led by molecular biologist Florian Raible from the Max Perutz Labs at the University of Vienna provides exciting insights into the bristles of the marine annelid worm Platynereis dumerilii.

In a joint project between MedUni Vienna and TU Wien, the world's first 3D-printed "brain phantom" has been developed, which is modelled on the structure of brain fibres and can be imaged using a special variant of magnetic resonance imaging (dMRI). As a scientific team led by MedUni Vienna and TU Wien has now shown in a study, these brain models can be used to advance research into neurodegenerative diseases such as Alzheimer's, Parkinson's and multiple sclerosis.

ISTA researchers welcome AI use in science, but remain cautious From identifying complex morphologies in the brain to analyzing the properties of storm clouds, artificial intelligence (AI) algorithms are aiding several research projects employing deep learning and machine learning at the Institute of Science and Technology Austria (ISTA).

A new approach to producing artificial tissue has been developed at TU Wien: Cells are grown in microstructures created in a 3D printer. Is it possible to grow tissue in the laboratory, for example to replace injured cartilage? At TU Wien (Vienna), an important step has now been taken towards creating replacement tissue in the lab - using a technique that differs significantly from other methods used around the world.

In the Christian Doppler Laboratory under his leadership, Franz Wotawa has developed test and monitoring procedures with company partner AVL that make common driver assistance systems safer. Intelligent Speed Assist, Emergency Brake Assist, Emergency Lane Keeping Assist, Driver Drowsiness Assist, Reversing Assist, Low Concentration Warning System or Emergency Brake Lights - from July 2024, a whole range of safety and driver assistance systems will be mandatory for all new cars in the European Union.

Positive experiences mitigate aversion to artificial intelligence as advice Generative artificial intelligence (AI) generates data that is similar to the human way of thinking. If a generative artificial intelligence such as ChatGPT functions as "practice advice" for overcoming personal or social challenges, it is considered by people to be less competent than human experts.

By Falko Schoklitsch Based on the vanillin made usable for electricity storage in 2020, an AI-optimised prototype of an environmentally friendly electricity storage system is now being developed in an international project. In 2020, Stefan Spirk from the Institute of Bioproducts and Paper Technology at Graz University of Technology (TU Graz) described the research achievement with which he and his team had succeeded as a "ground-breaking success in the field of sustainable energy storage technologies" to make redox flow batteries more environmentally friendly.

Researchers at TU Graz and the Helmholtz Center for Information Security have discovered a novel security gap in all common CPUs that can hardly be mitigated. Main processors (CPUs) of computers are designed to run multiple applications simultaneously. This is beneficial for efficiency, but poses a security risk.

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.

By Falko Schoklitsch Using a newly developed method for the efficient and cost-effective production of biocompatible microfibres, the production of autologous skin and organs can be significantly accelerated. In biomedical technology, tissue engineering for the ex-vivo production of skin or organs is becoming increasingly important.

Tiny tips on cantilevers are used to scan a surface in an atomic force microscope. A new invention from TU Wien now provides a simpler way to measure the result. The basic principle of the atomic force microscope is very simple: an extremely thin, movable tip on a cantilever is moved over a surface that is being examined.

By Chinese Academy of Sciences A study by a multinational research team with the participation of Graz University of Technology shows that the actual mass loss of numerous glaciers in the Himalayas has been significantly underestimated so far. A new insightful study reveals that the mass loss of lake-terminating glaciers in the greater Himalaya has been significantly underestimated, due to the inability of satellites to see glacier changes occurring underwater, leading to critical implications for the region's future projection of glacier disappearance and water resources.

Medicine & Science A study by the Medical University of Vienna has investigated the potential of artificial intelligence (AI) to address societal megatrends and analyzed its proposed solutions in dealing with these global challenges. Artificial intelligence can offer understandable insights into the complex and cross-cutting issues of megatrends, and how they could change and benefit in different areas if AI systems are deployed.

By Susanne Filzwieser Rail infrastructure is currently largely built and maintained using diesel-powered track-work machinery. Together with partners, TU Graz is investigating alternative drives for special machinery. For safe railway operation, tracks must be regularly maintained and renewed. This requires special construction machinery, most of which is nowadays powered by diesel engines.

By Birgit Baustädter Peter Brunnhofer works at the Institute of Structural Durability and Railway Technology to make trains lighter, more robust and more efficient. An interview with the researcher talking about lightweight construction. News+Stories: Why is the idea of lightweight construction for railed vehicles so important? Peter Brunnhofer : The interplay between the vehicle and the rails in railway transport is much more important than with cars on a road.

Researchers discover key to predicting the future of ecosystems Whether in the gut, in the lake, in the forest or in the meadow: All over nature, a wide variety of living organisms form ecosystems. How these develop is a question that is extremely relevant in both medicine and environmental protection.
