Mutable: Graz Researchers Decode Genome of Two Cichlid Species
Nature and man must constantly adapt to new living conditions. A research team from Graz has investigated how this is done and which genes play an important role in this process using the model system of the Great Lakes of East Africa. Global warming, environmental change, dried up food sources: nature and man must constantly adapt to new living conditions.

Quantum experiments that could previously only be performed with photons are now also possible with atoms: Beams of entangled atoms have been produced at TU Wien (Vienna). Heads or tails? If we toss two coins into the air, the result of one coin toss has nothing to do with the result of the other. Coins are independent objects.
Research association led by TU Graz wants to use the heat contained in the discharged tunnel water to supply energy to entire city districts. As part of the FFG programme "City of the Future", a sustainable concept for the city of Innsbruck is being developed.

Surprise in solid-state physics: The Hall effect, which normally requires magnetic fields, can also be generated in a completely different way - with extreme strength. Electric current is deflected by a magnetic field - in conducting materials this leads to the so-called Hall effect. This effect is often used to measure magnetic fields.
Experimental microbially assisted chemolithotrophy provides an opportunity to trace the putative bioalteration processes of the Martian crust. A study on the Noachian Martian breccia Northwest Africa (NWA) 7034 composed of ancient (ca. 4.5 Gyr old) crustal materials from Mars, led by ERC grantee Tetyana Milojevic from the Faculty of Chemistry of the University of Vienna, now delivered a unique prototype of microbial life experimentally designed on a real Martian material.
Quantum technologies for computers open up new concepts of preserving the privacy of input and output data of a computation. Scientists from the University of Vienna, the Singapore University of Technology and Design and the Polytechnic University of Milan have shown that optical quantum systems are not only particularly suitable for some quantum computations, but can also effectively encrypt the associated input and output data.
Noise limits the performance of modern quantum technologies. However, particles traveling in a superposition of paths can bypass noise in communication. A collaboration between the Universities of Hong-Kong, Grenoble and Vienna, as well as the Austrian Academy of Sciences, under the lead of Philip Walther, reveals novel techniques to reduce noise in quantum communication.
Currently there are more than 80 peptide drugs on the global market and about twice as many in clinical development. Due to their beneficial properties, these biomolecules play already an important role in the treatment of diseases such as diabetes, cancer, hormone disorders, HIV infection, and multiple sclerosis.
Microstructure and macroscopic electro-mechanical properties are closely coupled in so-called ferroelectric polymers. An explanation for the high temperature dependence of this coupling has now been found at TU Wien. In certain materials, electrical and mechanical effects are closely linked: for example, the material may change its shape when an electrical field is applied or, conversely, an electrical field may be created when the material is deformed.
In humans, differences in personalities have been evident since the ancient times. Personality in animals has long been ignored, but recently this question has received increasing research interest as it has been realized that personality has evolutionary and ecological significance. An international team of behavioral biologists from Austria, Brazil and the Netherlands, with Vedrana ¦lipogor from the University of Vienna as leading author of the study, designed a set of tasks to assess personality of common marmosets.
A team at TU Wien was able to answer important questions about the immune system - with a trick reminiscent of paper folding. T-cells are an important component of our immune system: with the receptors they carry on their surface, they can recognise highly specific antigens. Upon detection of an intruder, an immune response is triggered.
How do you measure objects that you can't see under normal circumstances? Utrecht University and TU Wien (Vienna) open up new possibilities with special light waves. Laser beams can be used to precisely measure an object's position or velocity. Normally, however, a clear, unobstructed view of this object is required - and this prerequisite is not always satisfied.
For years, the metal nanoparticles used in catalysts have been getting smaller and smaller. Now, a research team at TU Wien in Vienna, Austria have shown that everything is suddenly different when you arrive at the smallest possible size: a single atom. Metals such as gold or platinum are often used as catalysts.
Using mathematical image processing, scientists at the BioTechMed-Graz research cooperation have found a way to create digital twins from human hearts. The method opens up completely new possibilities in clinical diagnostics.

Agriculture and climate experts have warned for some years that extreme climate events including severe droughts with frequent heatwaves drop the production of major staple food crops like wheat causing a severe threat to food security.
In a new study, an international research team led by Sebastian Stumpf from the University of Vienna describes an exceptionally well-preserved skeleton of the ancient shark Asteracanthus. This extremely rare fossil find comes from the famous Solnhofen limestones in Bavaria, which was formed in a tropical-subtropical lagoon landscape during the Late Jurassic, about 150 million years ago.
With their expertise in microbiome research, the researchers at the Institute of Environmental Biotechnology were able to demonstrate how a specific bacterium inside the seeds of rice plants effectively and in an eco-friendly way inhibits destructive plant pathogens. Rice is the staple food of about half the world's population.
Why do metal oxide surfaces behave differently? At TU Wien, a new research method was found to answer important questions. Metal surfaces play a role as catalysts for many important applications - from fuel cells to the purification of car exhaust gases. However, their behaviour is decisively affected by oxygen atoms incorporated into the surface.
Changes in daylength are a well-established annual timing cue for animal behavior and physiology. An international collaboration of scientists led by Kristin Tessmar-Raible at the Max Perutz Labs, a joint venture of the University of Vienna and the Medical University of Vienna, now shows that, in addition to daylength, marine bristle worms sense seasonal intensity changes of UVA/deep violet light to adjust the levels of important neurohormones and their behavior.
