How can the use of plastics in agriculture become more sustainable?
How can the use of plastics in agriculture become more sustainable?
It is impossible to imagine modern agriculture without plastics. 12 million tonnes are used every year. But what about the consequences for the environment? An international team of authors led by Thilo Hofmann from the Division of Environmental Geosciences at the University of Vienna addresses this question in a recent study in Nature Communication Earth and Environment .

Sta­ti­stics of the invi­si­ble
In order to obtain information about dark matter and dark energy from the huge amounts of data to be generated by the new ESA probe Euclid, Innsbruck astrophysicist Laila Linke and her team are using novel statistical methods. As soon as Euclid sends its first data to Earth, the researchers intend to have a tool ready to gain new Astronomical measurements revealed that an unknown world lies hidden among all the pretty stars, nebulae and galaxies.

Small cell lung cancer: new approach to overcoming chemo-resistance
Small cell lung cancer: new approach to overcoming chemo-resistance
Small cell lung cancer accounts for about 15 percent of all diagnosed lung cancers and is still associated with a high mortality rate. SCLC tumours often develop resistance to chemotherapy and thus poor prognosis is due to tumour recurrence which occurs within only five to 14 months after initial diagnosis.

Glacier Loss Day as an indicator of glacier health
In the summer of 2022, one of Tyrol's largest glaciers recorded its largest mass loss ever. The Hintereisferner in the Ötztal valley reached its Glacier Loss Day (GLD) earlier than ever before. GLD serves as an indicator of a glacier's health over the course of the year, similar to how Earth Overshoot Day measures the Earth's resource consumption.

New gut microbe produces smelly toxic gas but protects against pathogens
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.

Autoimmune diseases: Protein discovered as potential new target for therapies
Autoimmune diseases are complex illnesses, the causes of which are diverse and have not yet been fully explained. 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. The identified component of the immune system is called "Rinl", which could provide a new target for the development of immunomodulatory therapies.

Golden future for thermoelectrics
Golden future for thermoelectrics
Researchers at TU Wien discover excellent thermoelectric properties of nickel-gold alloys. These can be used to efficiently convert heat into electrical energy. Thermoelectrics enable the direct conversion of heat into electrical energy - and vice versa. This makes them interesting for a range of technological applications.

Extremely high risk of further fractures in osteoporosis sufferers
Extremely high risk of further fractures in osteoporosis sufferers
Bone fractures due to osteoporosis are a major risk for the elderly. It is therefore all the more important to identify people at risk. An international team of authors with the participation of scientists from Med Uni Graz has analyzed how high the risk is of suffering a second bone fracture after the first: The risk is almost 90 percent higher.

Deep sea: Earthquake as engine for carbon cycle
Deep sea: Earthquake as engine for carbon cycle
As part of an international deep-sea expedition, a team of researchers under the co-leadership of Innsbruck geologist Michael Strasser took the deepest samples ever obtained from the seafloor at a depth of more than 8000 meters in the Japan Trench in 2021. Large amounts of dissolved carbon and enormous methane reservoirs were discovered in the seafloor, the formation of which is favored by the strong earthquake activity there.

Decoding Blood Platelet Production: The Intricate Role of Lipids
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.

Cause of rapid loss of vaccination protection in autoimmune diseases identified
People who are treated with TNF-α inhibitors for their autoimmune disease such as Crohn's disease or rheumatoid arthritis lose their vaccination protection significantly earlier than average. The mechanism underlying the early decrease in antibody levels has now been eludicated by a scientific team from MedUni Vienna.

Gene Mutation in the Immune System: Anti-Diabetes Drugs Make Immune Cells More Effective Again
Gene Mutation in the Immune System: Anti-Diabetes Drugs Make Immune Cells More Effective Again
T cells are an essential component of the immune system - they fight foreign structures such as bacteria and viruses or cancer-related changes in cells. This defense reaction requires energy. Scientists led by the St. Anna Children's Cancer Research Institute, MedUni Vienna and the Marmara University Istanbul have now shown for the first time that a defect in the gene for the transcription factor NFATC1 leads to an immune defect with a disruption of metabolism in T lymphocytes.

Targeting age-related diseases with biomarkers
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.

The Wild Boar Paradox - Finally Solved
The Wild Boar Paradox - Finally Solved
Decades after the Chernobyl nuclear accident, wild boar meat is still surprisingly radioactive. The solution to the riddle: an important other cause had been overlooked. The Chernobyl nuclear accident in 1986 had a major impact on the forest ecosystem in Central Europe. After the accident, the consumption of mushrooms was discouraged because of the high radioactive contamination, and the meat of wild animals was also severely affected for several years.

Surprising study results: Students are bored during exams
In the case of boredom, we think of many situations in life but intuitively not of exams. However, an international team of academics led by Thomas Götz from the University of Vienna has now studied exactly this phenomenon of test boredom for the first time and found remarkable results. According to the study, school students are actually very bored during exams.

Graphene: Perfection is futile
Graphene: Perfection is futile
The carbon material graphene has excellent electronic properties. But are they also stable enough to be useful in practice? Calculations from TU Wien say: Yes. Nothing in the world is perfect. This is also true in materials research. In computer simulations, one often represents a system in a highly idealized way; for example, one calculates the properties that an absolutely perfect crystal would have.
