Internet Security: the Danger of Nameless Cookies
Important security holes in modern Internet technology have been discovered by TU Wien (Vienna). Now the international IT community is working to close them. The Internet has undergone major technical changes in recent years, which has also led to new security problems. The IT security team at TU Wien (Vienna) analyzed security vulnerabilities that arise from the interaction of cookies and web frameworks - software packages that are often used today by web programmers to create websites.

New CPU security loophole: Analysis of energy consumption allows data theft
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.

Boost for the quantum internet
A quarter of a century ago, theoretical physicists at the University of Innsbruck made the first proposal on how to transmit quantum information via quantum repeaters over long distances which would open the door to the construction of a worldwide quantum information network. Now, a new generation of Innsbruck researchers has built a quantum repeater node for the standard wavelength of telecommunication networks and transmitted quantum information over tens of kilometers.

Better than Humans: Artificial Intelligence in Intensive Care Units
An artificial intelligence developed at TU Wien (Vienna) can suggest appropriate treatment steps in cases of blood poisoning. The computer has already surpassed humans in this respect. In the future, artificial intelligence will play an important role in medicine. In diagnostics, successful tests have already been performed: for example, the computer can learn to categorise images with great accuracy according to whether they show pathological changes or not.

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.

TU Graz and Intel Demonstrate Significant Energy Savings Using Neuromorphic Hardware
By Christoph Pelzl Research published in Nature Machine Intelligence illustrates neuromorphic technology is up to sixteen times more energy-efficient for large deep learning networks than other AI systems. For the first time TU Graz's Institute of Theoretical Computer Science and Intel Labs demonstrated experimentally that a large neural network can process sequences such as sentences while consuming four to sixteen times less energy while running on neuromorphic hardware than non-neuromorphic hardware.

Artificial neurons go quantum with photonic circuits
Quantum memristor as missing link between artificial intelligence and quantum computing In recent years, artificial intelligence has become ubiquitous, with applications such as speech interpretation, image recognition, medical diagnosis, and many more. At the same time, quantum technology has been proven capable of computational power well beyond the reach of even the world's largest supercomputer.

Foundations for Modern Distributed Computing
By Yannic Maus Many of today's and tomorrow's computer systems distribute data to several machines, or the systems are built on top of large-scale networks, such as the internet or sensor networks. Our research builds the theoretical foundations for these settings. We analyse and develop distributed algorithms that are fast and communication efficient.

Way to check that quantum computers return accurate answers
Quantum computers become ever more powerful, but how can we be sure that the answers they return are accurate? A team of physicists from Vienna, Innsbruck, Oxford, and Singapore solves this problem by letting quantum computers check each other. Quantum computers are advancing at a rapid pace and are already starting to push the limits of the world's largest supercomputers.

New insights into aortic dissection
By Birgit Baustädter Aortic dissection is a life-threatening tear in the aortic wall. At present, little is known about the causes. Researchers at TU Graz have now developed algorithms and models designed to support early-stage diagnosis and treatment. at the end of the message. In most cases, aortic dissection is the result of a tear in the inner layer of the aortic wall, the intima.

Reaching your life goals as a single-celled organism
How do simple creatures manage to move to a specific place? Artificial intelligence and a physical model from TU Wien can now explain this. How is it possible to move in the desired direction without a brain or nervous system? Single-celled organisms apparently manage this feat without any problems: for example, they can swim towards food with the help of small flagellar tails.

Understanding Human Behaviour with AI
By Birgit Baustädter Elisabeth Lex's research combines computer science methods with social science approaches, searching for clues to understand framing, polarisation and opinion clusters. More and more often, people are getting the feeling that society is increasingly polarised - regarding measures introduced during the Covid-19 pandemic, the question of vaccinations, elections, or environmental protection.

The Mathematics of Separate Things
By Birgit Baustädter Discrete mathematics is so much more than just "the language of computer science", as it is often referred to. But it is not "discrete" in the usual sense. Points are particularly discrete. Discrete mathematics derives from the Latin discernere, which means "to separate". "Discrete mathematics is about delimited or clearly separated objects - such as points, lines or sequences of integers," explains Oswin Aichholzer, a computer scientist at Graz University of Technology (TU Graz).
