’ChatGPT’ for biomedical simulations
The artificial intelligence (AI) model GPT-4, known from its application in ChatGPT, shows impressive capabilities in biomedical research and can be used in many ways for simulations. A simulator developed at MedUni Vienna and based on GPT-4 shows increased accuracy in classifying the importance of genes in cancer cells, as well as in the prognosis of cancer patients.

Postbuses collect insects for biodiversity throughout Austria
From the bus window to the DNA laboratory: Postbuses make the diversity of flying insects in Austria visible. The University of Innsbruck is launching an innovative project to record insect biodiversity. Wipe and know which insects fly in Austria: In the new biodiversity project of the Institute of Zoology at the University of Innsbruck, public transport in Tyrol, Carinthia, Lower Austria and Upper Austria is helping to study the diversity of microorganisms.

Breakthrough in bionic prostheses: Restoration of feeling possible with artificial limbs
Despite enormous progress over the past two decades, patients have not yet been able to feel a bionic prosthesis in a natural, intuitive way. Now a research team led by Oskar Aszmann from MedUni Vienna has made significant progress in sensitising the artificial extremities: By developing a new type of interface between man and machine, the feeling of the lost limb has been restored for the first time.

Long-standing marine mystery solved: How algae get nitrogen to grow
Long-standing marine mystery solved: How algae get nitrogen to grow
Newly discovered symbiosis between Rhizobia and diatoms could also open new avenues for agriculture In a new study, scientists from the Max Planck Institute for Marine Microbiology, the Alfred Wegener Institute and the University of Vienna shed light on an unexpected partnership: A marine diatom and a bacterium that can account for a large share of nitrogen fixation in vast regions of the ocean.

Progress in understanding metastatic melanoma
In a study recently published in the "British Journal of Cancer", a research team led by Mario Mikula from MedUni Vienna has shown that human skin organoids can be used to study the growth of malignant melanoma. The investigations using this instrument, which is extremely valuable for basic research, revealed that the loss of the neuronal protein NLGN4X in melanoma is associated with the progression of the disease, and that the loss of the neuronal protein NLGN4X is associated with the progression of the disease.

A Railroad of Cells
A Railroad of Cells
Looking under the microscope, a group of cells slowly moves forward in a line, like a train on the tracks. The cells navigate through complex environments. A new approach by researchers involving the Institute of Science and Technology Austria (ISTA) now shows how they do this and how they interact with each other.

Enzymes Instead of Cyanide: Researchers Develop Biocatalytic Process for Nitrile Production
Enzymes Instead of Cyanide: Researchers Develop Biocatalytic Process for Nitrile Production
A research team from TU Graz and the Czech Academy of Sciences has used two enzymes to eliminate the need for highly toxic cyanide in the production of nitriles. If the household cleaner emits a lemon-like odour, this may be due to a nitrile called citronellyl nitrile. These versatile chemical nitrile groups are also used in the manufacture of active pharmaceutical ingredients, superglue and chemical-resistant gloves.

New insights on polymicrobial infections in chronic lung diseases
Chronic lung diseases are often accelerated and exacerbated by polymicrobial infections. An international study team led by MedUni Vienna has identified two types of these so-called dysbioses in cystic fibrosis. They display distinct ecology and are also likely to respond differently to treatment. The study was published in the renowned journal Nature Communications.

Inhibition of epigenetic control enzymes in immune cells as a potential new starting point in cancer immunotherapy
Immunotherapy is one of the pillars in the fight against cancer and aims to enable the body's own immune system to fight a tumor. A recent study now shows that removing certain enzymes that regulate epigenetic processes from the so-called dentritic cells of the immune system influences their development and thus improves anti-tumor immunity.

Prostate cancer: Protein identified to reduce tumour growth
As prostate cancer progresses, it becomes increasingly aggressive and can metastasise. In this form, the tumour is difficult to treat, which is reflected in high mortality rates: Worldwide, the malignant disease of the prostate is the second most common cause of cancer death in men. An international study led by Lukas Kenner (MedUni Vienna) and Sabine Lagger (Vetmeduni Vienna) has now identified a protein that could slow tumour growth.

The Embryo Assembles Itself
The Embryo Assembles Itself
New mathematical framework sheds light on how cells communicate to form embryo Biological processes depend on puzzle pieces coming together and interacting. Under specific conditions, these interactions can create something new without external input. This is called self-organization, as seen in a school of fish or a flock of birds.

To grow their roots, plants feel gravity - ISTA scientists take a close look Using the force of gravity, roots weave their way through the soil to provide a plant with both structural support and essential nutrients. Anastasia Teplova from the Friml group at the Institute of Science and Technology Austria (ISTA) investigates the mechanism behind this process.

Brain organoid developed for research
The human brain is not only larger and contains more nerve cells than the control center of other species, it is also networked in a very special way: Thick bundles of nerves connect brain regions like highways over long distances, such as the left and right hemispheres of the brain. A team of researchers at IMBA, in cooperation with MedUni Vienna, has now presented the first organoid model in which these information "highways" can be studied.

New insights into the evolution of a water-saving trait in the pineapple family
Adaptation of the photosynthetic mechanism in air plants (Tillandsia) occurs through gene duplication Researchers at the University of Vienna, along with collaborators from France, Germany, Switzerland and the USA, have achieved a major breakthrough in understanding how genetic drivers influence the evolution of a specific photosynthesis mechanism in Tillandsia (air plants).

Genetic test for early detection of high cardiovascular risk
Genetic test for early detection of high cardiovascular risk
Clonal haematopoiesis is a phenomenon caused by mutations in haematopoietic stem cells and can lead to blood cancer. We now know that it occurs also in people with normal blood counts, where it is associated with an increased risk of life-threatening atherosclerotic cardiovascular disease. A research team at the Medical University of Vienna has now developed a genetic testing procedure to detect clonal haematopoiesis, which, when used in combination with an ultrasound examination of the carotid artery, allows to identify patients at high cardiovascular risk.

Biodiversity: climate becomes the main player
Biodiversity: climate becomes the main player
A recent study in the journal Science takes the most comprehensive look yet at the past and future of global biodiversity: intensive land use reduced biodiversity by up to around 10 percent over the course of the 20th century. By 2050, the climate crisis could become the main factor, alongside land use, for further losses in biodiversity.

Immune cells in the starting blocks: 'Always ready' is hard work
Immune cells in the starting blocks: ’Always ready’ is hard work
When pathogens invade the body, the immune system must react immediately and prevent or contain an infection. But how do our immune cells stay ready when there is no attacker in sight? Scientists from Vienna and Salzburg have come up with an intriguing explanation: They are stimulated by healthy tissue.
