Pflanzenzombies?

"The Last of Us" in real life!? Wie realistisch ist die Hype-Serie von HBO? Wir haben unsere Forscher gefragt.

Wie realistisch ist The Last of Us?

„Tatsächlich können Ophiocordyceps Spezies Insekten befallen und sie „zombieartig“ steuern. Sie sind aber spezialisiert und ein entsprechender Befall im Menschen würde einen langen Evolutionsprozess der Parasiten voraussetzen. Der Sprung auf einen Warmblütler wie einen Säuger ist evolutionsbiologisch nicht einfach. Dazu kommt noch die viel größere Komplexität der menschlichen Organe. Also ich habe bezüglich einer durch Ophiocordyceps orchestrierten Zombie-Apokalypse keinerlei Befürchtungen. Vielmehr sind andere Pilzspezies wie Candida eine echte und akute Bedrohung für uns“, so Uni-Graz-Molekularbiologe Didac Carmona-Gutierrez.

Pilzerkrankungen sind laut WHO gefährlich und müssen stärker erforscht werden. Warum?

Uni-Graz-Biologe Martin Grube: "Pilzinfektionen können ein immer größeres Risiko für die Gesundheit des Menschen darstellen, z.B. durch Pilzgruppen, die bei 37°C wachsen können. Weltweit sterben inzwischen mehr Menschen an akuten und chronischen Pilzinfektionen als an Malaria. In den vergangenen Jahren sind dabei auch multiresistente, kaum zu behandelnde Pathogene bekannt geworden, insbesondere bei der Hefe Candida auris. Daneben gibt es eine Reihe weiterer humanpathogener Pilze, die von der WHO als fungal priority pathogens gelisted sind."

Was sind die Ursprünge des Zombie-Mythos?

„Ursprünglich geht der Zombie-Mythos auf afrikanische und haitianische Folklore-Traditionen zurück, in denen Zombies als Untote dargestellt werden, die von einem Magier wiederbelebt werden und ihm gehorchen müssen. In der amerikanischen Kultur wurde der Zombie-Mythos in den 1940er-Jahren durch den Film I Walked with a Zombie von Jacques Tourneur aufgegriffen. Der Durchbruch für den modernen Zombie-Mythos kam 1968 mit George A. Romeros Film Night of the Living Dead“, fasst Uni-Graz-Amerikanist Stefan Brandt die Anfänge zusammen.

Austria’s emissions rose in 2025: University of Graz researchers analyse the causes

The Environment Agency Austria has today published the figures for the country’s greenhouse gas emissions in 2025. While emissions fell sharply year on year from 2022 to 2024, they rose again by just under 0.7 per cent in 2025. Researchers at the University of Graz have analysed how much of this increase was due to structural changes in the economy and how much was attributable to external factors over which there is little control. “In 2025, the colder winter compared with 2024 increased emissions by 0.81 per cent, while the weak economy reduced them by 0.38 per cent. If we factor out these influences, we find an underlying increase of 0.26 per cent compared with the previous year,” reports economist Karl Steininger. “This clearly means that Austria is not on track to meet its climate targets, which require a substantial reduction in emissions by 2030.”

Electrifying: Researchers film the first moments on the way from light to electricity

Physicists at the University of Graz (Austria), in collaboration with colleagues from Marburg University and Forschungszentrum Jülich (Germany), have achieved a scientific breakthrough. For the first time, the generation of electrical energy from light has been filmed and described theoretically. This work is of far-reaching significance, not least for optimising sustainable energy production from photovoltaics. This is because it provides fundamental building blocks for understanding the physical processes that take place, for example, in organic solar cells. The paper was published in the journal Physical Review X, one of the world’s most prestigious physics journals.

How can we teach using YouTube and AI? The University of Graz is strengthening media education in schools

A journey through the blood vessels using VR headsets brings biology lessons to life. An interactive quiz brings physics to life. The YouTube video explains the First World War. Whilst mobile phones are increasingly being banned from the classroom, social media platforms, apps and AI are playing an ever-greater role in knowledge transfer at school. But how can teaching with media be made even more effective? What are the challenges in media-based teaching? At the University of Graz, researchers are discussing these issues at a conference being held in Austria for the first time.
