Ein Himmel voller Rätsel

JungforscherInnen der Uni Graz nutzen Nobelpreis-Methode zur Erforschung des Universums und vernetzen sich mit internationalen Größen

Mit der Beobachtung von Gravitationswellen sorgten WissenschafterInnen vor wenigen Wochen für Furore. Nachdem zwei Neutronensterne – quasi Sternenleichen – aufeinandergeprallt waren, konnte nicht nur die durch die Explosion freigesetzte Strahlung gemessen, sondern erstmals auch durch Teleskope verfolgt werden. Dabei konnte man auch nachweisen, dass viele schwere Elemente bei solchen Ereignissen entstehen. Die aufgezeichneten Daten nutzen JungforscherInnen an der Uni Graz: Im Rahmen des Doktoratskollegs „Hadronen im Vakuum, in Kernen und Sternen“ gehen sie einigen grundlegenden Fragen über den Aufbau von solchen Neutronensternen und damit den Voraussetzungen für die Entstehung von Gold, Blei oder Uran nach. „Derzeit sind noch sehr viele Dinge ungeklärt“, weiß Teilchenphysiker Axel Maas, der an der Uni Graz in dem Bereich forscht. Eigenschaften von Neutronensternen sowie die heuer mit dem Physik-Nobelpreis gekrönte Methode zur Messung von Gravitationswellen stehen auch im Zentrum einer Fachtagung von 23. bis 24. November, zu der Koryphäen aus Italien, Spanien und den USA an die Uni Graz kommen.

Jurassic Sounds: Biologist reconstructs insect songs from 165 million years ago

It was apparently not just the roars of the dinosaurs that made up the soundscape of the animal world during the Jurassic period. Crickets and grasshoppers communicated through a variety of songs and high-pitched sounds, as Thorin Jonsson from the Institute of Biology at the University of Graz discovered together with colleagues from the universities of Lincoln, Bristol (UK), Beijing (China) and Tempe (USA). The findings on what are so far the oldest traces of sound on Earth have just been published in the journal PNAS.

EU funding boosts international exchange between universities

The University of Graz is further expanding its international study opportunities through the European university alliance Arqus and is taking the lead in two key projects. In future, students will benefit from even more joint degree programmes and from simplified recognition of academic achievements through the Joint European Degree Label.

Rescue and risks: Researchers have surveyed public perceptions of AI

The use of artificial intelligence has had to be made transparent since 2 August 2026. The EU’s AI Act, which has been in force since then, also sets out how risky an application is and which security measures apply as a result. However, the assessment of risks by the legislation differs in some cases significantly from the perceptions of the Austrian public. This is the finding of a representative study carried out by data scientist Stefan Thalmann from the University of Graz and his team.

The Healing Sea: Researchers discover new approaches to treating chronic inflammation in sponges

Chronic inflammation plays a key role in many diseases, ranging from metabolic disorders and cardiovascular diseases to tissue damage following injuries or infections. “Normally, the body is able to resolve inflammation on its own. If this process becomes unbalanced, immune cells remain permanently active and continue to drive negative changes in the tissue,” explains Andreas Koeberle, a pharmacist at the University of Graz.
