Nordlichter entstehen, wenn geladene Teilchen des Sonnenwindes auf die Erdatmosphäre in den Polargebieten der Erde treffen. Diese Woche ist das Phänomen auch in Österreich zu sehen. Foto: Polarlicht auf Island by Theo Schacht CC-BY-SA 3.0 de (http://bit.ly/1eFBTml)

Aufgrund heftiger Sonnenstürme können Nordlichter bis zum Wochenende auch über Österreich gesehen werden

Derzeit befindet sich die Erde in einem Sonnensturm: „Er ist mit Sicherheit der zweitstärkste geomagnetische Sturm des jetzigen Sonnenzyklus und hat gute Chancen, zum heftigsten zu werden“, weiß Astrophysiker Dr. Christian Möstl von der Karl-Franzens-Universität. Einen weiteren Sturm erwarten die ExpertInnen der Uni Graz und des Instituts für Weltraumforschung für morgen.

„Leider haben wir gerade die Sommersonnenwende, dadurch ist es nicht wirklich lange dunkel, dazu kommt das für Beobachtungen ungünstige Regenwetter. Aber es besteht auch heute Nacht und bis zum Wochenende hin noch die Chance, Nordlichter zu sehen - auch über Österreich", erklärte Möstl. Seine Kollegin Priv.-Doz. Dr. Manuela Temmer und er sagten beide die Ankunft des Sonnensturms bis auf wenige Stunden genau voraus. Durch diese exakten Beobachtungen könnte man im Ernstfall auch reagieren: Zu großflächigen Stromausfällen dürfte es laut Möstl aber nicht 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.
