On the 180th anniversary of Ludwig Boltzmann's birth: Physics building receives award

The physics building at Universitätsplatz 5 received a special distinction: it was included as number 75 in the "Historic Sites" of the European Physical Society. And this just in the 180th year of the birth of the University of Graz researcher Ludwig Boltzmann

Spatenstich für das „Graz Center of Physics“: Spitzenforschung wird sichtbarer

Am 4. Juni 2024 erfolgte in Anwesenheit von Bundesminister Martin Polaschek der Spatenstich für das neue Graz Center of Physics (GCP). Nach dem Abbruch der ehemaligen Vorklinik beginnt nun mit dem Aushub der Baugrube die nächste wichtige Phase für eines der größten Universitätsbauprojekte Österreichs. Der nachhaltige Neubau wird die Physik-Institute von Universität Graz und TU Graz ab dem Jahr 2030 an einem gemeinsamen Standort vereinen.

Research for healthy aging: FWF funds Cluster of Excellence "MetAGE" with 18 million euros

Six researchers from the Field of Excellence "BioHealth" at the University of Graz, together with colleagues from the Medical Universities of Graz and Vienna, have acquired an FWF-funded "Cluster of Excellence". Now a newly formed center of excellence will be created under the leadership of the University of Graz. The aim is to gain a better understanding of healthy aging. The findings will flow directly into clinical research.

Rising cost of living for insects: Energy demand increases with climate change

It sounds paradoxical: when the climate gets warmer, insects need more energy. Biologists at the University of Graz have demonstrated this using the example of paper wasps of the genus Polistes. Their mated queens spend the cold season in hidden winter quarters and live on the reserves built up in autumn. "A special metabolic characteristic of insects is that their energy requirements increase exponentially at rest as the outside temperature rises," says Anton Stabentheiner, lead author of the study, which was recently published in the Journal of Comparative Physiology B.

Short but powerful: PhD students present their research in the 3 Minute Thesis Competition

Brevity is the soul of wit - a saying that was confirmed at the Three Minute Thesis Competition (3MT) on 15 March 2024. Eleven doctoral students from the University of Graz took part in the event organised by the Doctoral Academy as part of an international competition. The task: to present their own research in English in three minutes in an understandable and exciting way for an audience from outside the field. Allowed: a single PowerPoint slide and a lot of creativity. All participants demonstrated this on stage at the Literaturhaus Graz.

Amino acids stimulate protein partnership

It is one of the key enzymes for the lipid catabolism in the body: ATGL (adipose triglyceride lipase). It was discovered at the University of Graz in 2004. Stimulated by its partner protein CGI-58, it ensures the release of fatty acids into the bloodstream. This process is crucial for metabolic balance. Chronically elevated fatty acid levels are the cause of heart disease, fatty liver or diabetes, among other things. Inhibiting ATGL can alleviate these disorders. For new therapeutic approaches, it is therefore crucial to know the molecular mechanisms of action in detail. Scientists at the University of Graz have now discovered amino acids that are required in ATGL to be stimulated by CGI-58. The study was published in the Journal of Lipid Research.

New photonic chip can generate and measure customised light fields for the first time

They send light, like tiny cars, along sophisticated paths across a silicon surface. And they do this on a chip the size of the tip of a small finger. In these waveguides, they have the light firmly under control. Researchers at the University of Graz have succeeded for the first time in operating a system that simultaneously fulfills two different functions on an integrated photonic chip: Not only can the incident light be measured, but a light field with specific properties can now also be generated in a targeted manner. The work is a milestone for the interaction of light fields and integrated optical circuits and opens doors for many new applications in sensor technology, communication and imaging.

Plankton and ice: How global warming is changing the supply of nutrients in the oceans

Climate change not only affects weather phenomena such as El Niño or the monsoon, but also ocean currents and consequently the food chain. The associated disappearance of fishing grounds could have massive ecological and economic consequences. How ice melt, ocean circulation and nutrient content interact is not yet fully understood. Gerald Auer uses primeval soil samples to investigate the background.
