Researchers at TU Graz Decipher Enzyme Scissors of Intestinal Microbes
Flavonoids & Co: Microorganisms in the human gut utilise so-called beta-elimination to break down plant natural products and thus make them available to humans. Fruit and vegetables contain a variety of plant natural products such as flavonoids, which give fruits their colour and are said to have health-promoting properties.

’Zoom Fatigue’: Exhaustion caused by video conferencing proven on a neurophysiological level for the first time
By Philipp Jarke Using EEG and ECG data, researchers at the University of Applied Sciences Upper Austria and Graz University of Technology were able to prove that video conferences and online education formats lead to greater fatigue than face-to-face alternatives. Following the COVID-19 pandemic, the increase in virtual interactions has created a new challenge: fatigue caused by video calls, also known as Zoom fatigue or videoconference fatigue.

Why parents should sing to their babies
Why parents should sing to their babies
Play songs shape the language skills of young children Parents often sing lullabies or happy play songs to their babies. But how do babies react to these everyday songs - and what role do they play in child development? A research team from the University of Vienna in collaboration with the University of East London investigated these questions in a recent study.

Microbiome of Fruit and Vegetables Positively Influences Diversity in the Gut
Microbiome of Fruit and Vegetables Positively Influences Diversity in the Gut
In a meta-study, a research team from the Institute of Environmental Biotechnology at TU Graz has provided evidence that the consumption of fruit and vegetables contributes positively to bacterial diversity in the human gut. Bacterial diversity in the gut plays an important role in human health. The crucial question, however, is where are the sources of this diversity? It is known that an important part of the maternal microbiome is transferred to the baby at birth, and the same happens during the breastfeeding period via breast milk.

Head or egg: an evolutionary trade-off
Head or egg: an evolutionary trade-off
Would you rather lay lots of eggs - or grow your own head back? In the evolutionary history of flatworms, some species apparently had to choose one of the two abilities. This is what a team of scientists found out when they investigated the regenerative ability of planarians. Bernhard Egger, who heads the Regeneration Group at the Institute of Zoology at the University of Innsbruck and was involved in the study, reports on the amazing properties of these animals .

New insights into the genetics of the common octopus: genome at the chromosome level decoded
New insights into the genetics of the common octopus: genome at the chromosome level decoded
Scientific milestone provides deeper insights into the evolution and biology of Octopus vulgaris Octopuses are fascinating animals - and serve as important model organisms in neuroscience, cognition research and developmental biology. To gain a deeper understanding of their biology and evolutionary history, validated data on the composition of their genome is needed, which has been lacking until now.

Art with DNA - Digitally creating 16 million colors by chemistry
Art with DNA - Digitally creating 16 million colors by chemistry
The DNA double helix is composed of two DNA molecules whose sequences are complementary to each other. The stability of the duplex can be fine-tuned in the lab by controlling the amount and location of imperfect complementary sequences. Fluorescent markers bound to one of the matching DNA strands make the duplex visible, and fluorescence intensity increases with increasing duplex stability.

New AI technique enables rapid digital tissue analysis for brain tumor surgery
New AI technique enables rapid digital tissue analysis for brain tumor surgery
The Department of Neurosurgery at MedUni Vienna and University Hospital Vienna has recently begun using a new laser-based imaging technique that enables much faster tissue diagnosis during tumor surgery. With "Stimulated Raman Histology", a digital tissue section can be created directly in the operating room, which can be accessed and diagnosed after just a few minutes.

Microbial Metabolites: A New Link to Parkinson's Disease?
Microbial Metabolites: A New Link to Parkinson’s Disease?
Researchers from the University of Vienna, University of Konstanz, and Albert Einstein College of Medicine uncover a potential environmental trigger for Parkinson's disease. Published in Environment International , a groundbreaking study from the Institute of Biological Chemistry and Centre for Microbiology and Environmental Systems Science (CeMESS) at the University of Vienna, in collaboration with the University of Konstanz and the Albert Einstein College of Medicine, reveals a microbial metabolite's role in inducing Parkinson's-like symptoms.

New insights into the development of sarcoidosis
New insights into the development of sarcoidosis
Sarcoidosis is an inflammatory disease in which immune cells form tissue nodules in various organs, which can drastically impair organ function. Now a MedUni Vienna research team led by Thomas Weichhart from the Center for Pathobiochemistry and Genetics has developed an animal model that replicates the development of the disease in the heart and can contribute to research into sarcoidosis.

Cats purr differently than previously thought
Cats purr differently than previously thought
The cat larynx can produce purring sounds without cyclical neural input A recent investigation led by voice scientist Christian T. Herbst from the University of Vienna, published in Current Biology, delivers novel insights into how cats produce their purring sounds. A special 'pad' embedded in the vocal folds might explain why the cats can produce these low-frequency sounds.

Soil bacteria prevail despite drought conditions
Soil bacteria prevail despite drought conditions
Real-world climate change experiment reveals surprising soil response Recent research uncovers the resilience of certain soil microorganisms in the face of increasing drought conditions. While many bacteria become inactive during dry spells, specific groups persist and even thrive. This study, conducted by the Centre for Microbiology and Environmental Systems Science (CeMESS) at the University of Vienna, offers ground-breaking insights into bacterial activity during drought periods, with implications for agriculture and our understanding of climate change impacts.

Autoimmune diseases: Protein discovered as potential new target for therapies
Autoimmune diseases are complex conditions whose causes are diverse and have not been fully elucidated to date. A research team at MedUni Vienna has now discovered an immunoregulatory protein that could be linked to the development of autoimmune diseases such as rheumatoid arthritis. -Rinl- is the name of the identified building block of the immune system, which may provide a new starting point for the development of immunomodulatory therapies.
