Obser­ving macros­co­pic quan­tum effects in the dark
Obser­ving macros­co­pic quan­tum effects in the dark
Be fast, avoid light, and roll through a curvy ramp: This is the recipe for a pioneering experiment proposed by theoretical physicists in a recent paper published in Physical Review Letters. An object evolving in a potential created through electrostatic or magnetic forces is expected to rapidly and reliably generate a macroscopic quantum superposition state.

Possible trigger of chronic inflammatory bowel disease identified
As the cause of chronic inflammatory bowel diseases (IBD) such as Crohn's disease or ulcerative colitis is not yet known, treatment for sufferers is currently aimed at alleviating the often agonising symptoms. The discovery by a MedUni Vienna research team that the trigger for IBD could be found on the surface of intestinal epithelial cells provides a new potential starting point for the development of therapeutic measures.

Stranger than Friction: A Force Initiating Life
Scientists examine how friction forces propel development in a marine organism As the potter works the spinning wheel, the friction between their hands and the soft clay helps them shape it into all kinds of forms and creations. In a fascinating parallel, sea squirt oocytes (immature egg cells) harness friction within various compartments in their interior to undergo developmental changes after conception.

Shape matters: How microplastic travels that far
Shape matters: How microplastic travels that far
New study: Microplastic fibers are settling substantially slower than spherical particles in the atmosphere and might even reach stratosphere How far microplastics travel in the atmosphere depends crucially on particle shape, according to a recent study by scientists at the University of Vienna and the Max Planck Institute for Dynamics and Self-Organisation in Göttingen: While spherical particles settle quickly, microplastic fibers might travel as far as the stratosphere.

Survey shows skepticism towards generics and biosimilars among healthcare professionals in Vienna
A recent study by the Medical University of Vienna sheds light on the perception and knowledge of healthcare professionals regarding generics and biosimilars. A survey showed that there is still widespread skepticism and large gaps in knowledge about these medicines. The results were published in the European Journal of Clinical Pharmacology.

The rock that creates clouds
The rock that creates clouds
Feldspar is very common in rocks. As atmospheric dust, this mineral contributes efficiently to cloud formation. Researchers at TU Wien have now discovered what happens during this process. Feldspar is a ubiquitous mineral and makes up about half of the Earth's crust. In the Earth's atmosphere, feldspars play a surprisingly important role.

The Snail or the Egg?
The Snail or the Egg?
How marine snails switched from laying eggs to giving birth Animals reproduce in one of two distinct ways: egg-laying or live birth. By studying an evolutionarily recent transition from egg-laying to live-bearing in a marine snail, collaborative research by the Institute of Science and Technology Austria (ISTA), the University of Sheffield, and the University of Gothenburg has shed new light on the genetic changes that allow organisms to make the switch.

Women from low socio-economic backgrounds see themselves as less talented
How distorted self-images carry a negative impact on chances of success Women from low socio-economic backgrounds consider themselves to be less talented than all other groups - even if they show the same performance levels. This is shown by a new study led by Christina Bauer at the University of Vienna.

Framework created for improved imaging diagnostics of brain tumors
Diffuse gliomas are malignant brain tumors and cannot be optimally examined by conventional imaging using MRI. Amino acid PET can better visualize the activity and spread of gliomas. An international research group (RANO Group) led by MedUni Vienna and LMU Munich has now established the first international criteria for standardized imaging of gliomas using amino acid PET.

Prin­ting inks made from plants
On the path to a circular economy, Judith Deriu is developing natural color pigments from plants and uses them to make sustainable printing inks for industry in the laboratory at the Research Institute of Textile Chemistry and Textile Physics in Dornbirn. Natural dyes have been used by humans for centuries.

Brisk walks sup­port smo­king ces­sa­tion
Good news for anyone who wants to quit smoking in the new year: In a recently published study, Innsbruck scientists show that ten-minute brisk walking sessions reduce the cravings of temporarily abstinent smokers and improve their overall well-being. The study is the first to compare the effect of indoor and outdoor activity on smoking cessation.

Research Team Monitors Critical Infrastructure Using Navigation Satellites
Researchers at TU Graz have developed a new measuring system that can statically and dynamically monitor the condition of buildings using just a few antennas. From the outside, the Kölnbrein water dam, operated by Verbund in Carinthia, which is Austria's highest dam, and the DC Tower in Vienna, Austria's tallest building, do not have much in common, but for a research group around Caroline Schönberger and Werner Lienhart from the Institute of Engineering Geodesy and Measurement Systems at Graz University of Technology (TU Graz), they are equally interesting from a scientific point of view.

Clarified at last: the physics of popping champagne
Clarified at last: the physics of popping champagne
When you uncork a bottle of champagne, complex supersonic phenomena occur. Scientists at TU Wien have now been able to calculate exactly what happens for the first time. It sounds like a simple, well-known everyday phenomenon: there is high pressure in a champagne bottle, the stopper is driven outwards by the compressed gas in the bottle and flies away with a powerful pop.

Unconventional magnets: stress reduces frustration
Unconventional magnets: stress reduces frustration
An international research team recently demonstrated how magnetism can be actively changed by pressure. Magnetism occurs depending on how electrons behave. For example, the elementary particles can generate an electric current with their charge and thereby induce a magnetic field. However, magnetism can also arise through the collective alignment of the magnetic moments (spins) in a material.

2023: A Year of Research Successes at TU Graz
At Graz University of Technology (TU Graz) in 2023, important discoveries were made, new insights gained and exciting information gleaned. An end-of-year review. TU Graz in Space In 2013, the small satellite TUGSAT-1 was Austria's first satellite in space. It was built at TU Graz and has been observing the earth from low earth orbit ever since.

FWF funding for research into new treatment options for prostate cancer
Many patients with prostate cancer develop androgen-independent tumor growth, which is referred to as castration-resistant prostate cancer (CRPC). In these patients, activation of the androgen receptor (AR) in the tumors no longer requires androgen stimulation, and therapy with androgen inhibitors becomes ineffective.

Child and adolescent psychiatry: fewer coercive measures thanks to architectural changes
Child and adolescent psychiatry: fewer coercive measures thanks to architectural changes
Coercive measures are used in psychiatric treatment to avert acute danger to a person's life and health. However, such measures can be associated with considerable risks for patients and treatment teams. It is known from studies in adult psychiatric inpatient wards that environmental factors such as staffing, availability of retreat options, privacy and access to natural light can influence the use of coercive measures.

Multiple sclerosis: Possible basis for vaccine researched
Multiple sclerosis (MS) is a chronic inflammatory autoimmune disease in which the Epstein-Barr virus (EBV) is thought to play a role that has not yet been fully clarified. In particular, it was previously unclear why almost all people are infected with EBV in the course of their lives, but the virus only triggers MS in a small number of people.
