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
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
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
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.

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
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
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.

New gut microbe produces smelly toxic gas but protects against pathogens
Taurine-degrading bacteria influence intestinal microbiome An international team of scientists led by microbiologist Alexander Loy from the University of Vienna has discovered a new intestinal microbe that feeds exclusively on taurine and produces the foul-smelling gas hydrogen sulfide. The researchers have thus provided another building block in the understanding of those microbial processes that have fascinating effects on health.

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.

Decoding Blood Platelet Production: The Intricate Role of Lipids
Disruptions in lipid metabolism might affect platelet production. Scientists unveiled a deeper understanding of megakaryocyte differentiation and blood platelet production, a process crucial for maintaining healthy blood clotting and preventing excessive bleeding. The study featured in "Nature Cardiovascular Research," led by chemist Robert Ahrends from the University of Vienna and cardiologist Oliver Borst from the University of Tübingen, sheds light on the intricate role of lipids - the building blocks of cell membranes - in the formation of these vital blood components.

Targeting age-related diseases with biomarkers
Innsbruck researchers are making a major contribution to a new international concept for aging research. A new framework for so-called biomarkers makes it easier to define the biological process of aging. In this way, the researchers are also opening up new avenues for the prevention of age-related diseases.

Hallstatt: 3,000-year-old intestinal parasites of miners analysed
Researchers in Vienna have obtained the world's first gene sequences of the human roundworm from the Bronze Age, as well as the first gene sequences from prehistoric parasites in Austria. The analysis was conducted on human faeces from prehistoric miners in Hallstatt. The findings were published by a team from the Medical University Vienna, the Austrian Academy of Sciences (OeAW) and the Natural History Museum Vienna in the journal Nature Scientific Reports.

Lipid Chemistry Empowers Nuclear Shape
The cell nucleus is surrounded by a spherical double membrane called the nuclear envelope. Scientists have long been intrigued by how this envelope can be elastic enough to accommodate shape changes that cells experience as they move through tissues, but also rigid enough to maintain nuclear integrity.

On-off switch for enzymes
Researchers at TU Graz have gained new insights into the functioning of a protein found in bacteria, whose enzymatic activity is activated by blue light. Light affects living organisms in many different ways: for example, plants orient their growth direction towards the sun, while circadian rhythms in humans are controlled by daylight.

Multiple sclerosis: new biomarker confirmed for early diagnosis
A study conducted by researchers from the Department of Neurology at MedUni Vienna and University Hospital Vienna has demonstrated for the first time that diagnosis of multiple sclerosis (MS) can be significantly improved by additionally measuring the thickness of retinal layers in the eye. Use of the procedure, which is already available at the Departments of MedUni Vienna and University Hospital Vienna, helps to detect the condition at an earlier stage and predict its progression more accurately.

Brain: MRI scans may reveal risk of brain hemorrhage
When people talk about a stroke, they are usually referring to ischemic stroke, in which an artery in the brain becomes blocked and affected areas of the brain are subsequently no longer supplied with nutrients and oxygen. Cerebral hemorrhage is another form of this medical emergency, in which a blood vessel bursts.
