Identification of specific immune cells using fluorescence and digital histology in brain tumour operations
An international team of researchers with significant involvement from the Department of Neurosurgery at Vienna General Hospital and MedUni Vienna has made significant progress in the visualisation of difficult-to-detect brain tumours during surgery. The recently published study is the first to investigate the combined use of 5-aminolevulinic acid (5-ALA) and digital stimulated Raman histology (SRH), a new type of microscopic fluorescence analysis tool. It has been shown for the first time that 5-ALA fluorescence can be used to identify not only tumour cells but also certain immune cells, which are an important part of the tumour microenvironment, in glioblastoma, the most common malignant primary brain tumour in adults.

ISTA scientists predict-and witness-evolution in a 30-year marine snail experiment Snails on a tiny rocky islet evolved before scientists' eyes. The marine snails were reintroduced after a toxic algal bloom wiped them out from the skerry. While the researchers intentionally brought in a distinct population of the same snail species, these evolved to strikingly resemble the population lost over 30 years prior.

Ring trial enables establishment of ceramide reference values Results of the first phase of a Ceramide Ring Trial have just been published in the renowned journal Nature Communications , representing a significant landmark in the field of lipidomics. This achievement, involving researchers at the University of Vienna and scientific teams in Singapore, Julich and Espoo, represents a groundbreaking advance in the establishment of ceramide reference values, plasma lipids involved in such as cardiovascular diseases.

How a bunch of seemingly disorganized cells go on to form a robust embryo Embryo development starts when a single egg cell is fertilized and starts dividing continuously. Initially a chaotic cluster, it gradually evolves into a highly organized structure. An international team of researchers including scientists from the Institute of Science and Technology Austria (ISTA) has provided new insights into the process, emphasizing the critical role of both chaos and order.

Improved Glacier Monitoring Using Satellite Radar
International researchers involving Graz University of Technology have used radar data to determine which glaciers in High Mountain Asia are growing or shrinking in which season. For parts of Central Asia and the Himalayas, the findings contradict previous assumptions. Glaciers are dynamic entities: over the course of the year, phases of mass growth, particularly due to snowfall, alternate with periods in which glaciers lose mass.

Despite the same pelvis-to-head ratio, Japanese macaques do not suffer the same birth complications as humans An international research team led by the University of Vienna and the Medical University of Vienna has used long-term demographic data from Japanese macaques - a monkey species within the family of Old World monkeys - to show that, unlike humans, there is no maternal mortality in these primates linked to childbirth.

Spintronics: significant progress
An international research team has achieved a breakthrough in atomically thin antiferromagnetic tunnel junctions. This shows the great potential of antiferromagnetic materials for storage technology. Spintronics (spin electronics) deals with the use of electron spin in electronic devices. In contrast to conventional electronics, which only uses the charge of the electrons, spintronics also uses the spin of the electrons, i.e. a "direction of rotation" at the atomic level, to store and process information.

Integrating post-quantum security algorithms into hardware was previously considered a challenge. A research team at Graz University of Technology has developed standardized hardware with additional security measures. They are not yet a reality, but in the not too distant future, sophisticated, powerful quantum computers will be available.

Help in the search for missing persons: New JKU method enables three-dimensional perception of drone images in real time. This works even with strong occlusion and at long distances. Human visual depth perception, i.e. the ability to perceive objects at different distances, is essentially based on the fact that our eyes see slightly different images in terms of perspective.

A Viral Close-Up
Almost everyone knows about HIV. Fewer people know about its relative, HTLV-1. However, HTLV-1 can cause serious illnesses, including cancer. To develop ways to combat this virus, understanding its structure is essential. Martin Obr and Florian Schur from the Institute of Science and Technology Austria (ISTA) and US colleagues now show the virus in close-up in a new paper, published in Nature Structural & Molecular Biology .

Using smartly trained neural networks, researchers at TU Graz have succeeded in generating precise real-time images of the beating heart from just a few MRI measurement data. Other MRI applications can also be accelerated using this procedure. Medical imaging using magnetic resonance imaging (MRI) is very time-consuming since an image has to be compiled from data from many individual measurements.

Palaeontologists trace the influence of humans using predatory snail boreholes Predatory snails drill holes in the shells of their prey. Using these boreholes, a research team led by palaeontologist Martin Zuschin from the University of Vienna was able to create a time series of predator-prey relationships in the northern Adriatic over the past millennia.

20 years of microplastics research: time to act
Science has provided more than enough evidence to develop a collective and global approach to tackle the proliferation of plastic pollution. This is the conclusion of an international research team including environmental psychologist Sabine Pahl from the University of Vienna. The current Science publication particularly emphasises the urgency of a global agreement to curb plastic pollution.

Bleeding risk underestimated in patients with cancer
In a recent study published in the scientific journal "Blood", researchers from MedUni Vienna show that haemorrhages are more common in cancer patients than previously thought and are associated with a poor prognosis and an increased risk of death. The results emphasise the need to devote more attention to this serious complication in clinical practice and research in the future.

Mammals with distant evolutionary ties but similar ecological roles evolved comparable inner ear shapes A new study reveals the surprisingly convergent evolution in the inner ear of mammals. An international research team led by Nicole Grunstra from the University of Vienna and Anne Le Maître from the Konrad Lorenz Institute (KLI) for Evolution and Cognition Research (Klosterneuburg) showed that a group of highly divergent mammals known as Afrotheria and distantly related, but ecologically very similar mammals independently evolved similar inner ear shapes.

In contrast to annual plants, perennial wheat offers a more diverse microbiome and has a significantly lower impact on soil and environment - as has just been proven by researchers at TU Graz's Institute of Environmental Biotechnology. From an ecological point of view, the cultivation of annual cereal crops is a burden on nature.
