Molecular mechanism controlling the development of neurons in the hypothalamus is discovered
Molecular mechanism controlling the development of neurons in the hypothalamus is discovered
An international study led by MedUni Vienna has identified the transcription factor ONECUT3 as a regulator of the development of neurons in the hypothalamus. Transcription factors such as ONECUT3 are proteins that control the activity of genes. The hypothalamus is a region of the brain that acts as an interface between the brain and body through hormone production, to control metabolism, growth, parenting and others.

Dandelion-Shaped Supernova
Dandelion-Shaped Supernova
A historical supernova documented by Chinese and Japanese astronomers in 1181 has been lost for centuries, until very recently. Yet, the newly found remnant shows some stunning characteristics that are puzzling astronomers. Now, it surrenders its secrets. A team led by Tim Cunningham from the Center for Astrophysics, Harvard & Smithsonian, and Ilaria Caiazzo, Assistant Professor at the Institute of Science and Technology Austria (ISTA), provides the first detailed study of the supernova's structure and speed of expansion in 3D.

Complex Sound Patterns are recognized by newborn brains
Complex Sound Patterns are recognized by newborn brains
Nonlinguistic Sounds Activate Language-Related Networks in the Brain A team of researchers, including psycholinguist Jutta Mueller from the University of Vienna, has discovered that newborns are capable of learning complex sound sequences that follow language-like rules. This groundbreaking study provides long-sought evidence that the ability to perceive dependencies between non-adjacent acoustic signals is innate.

Understanding Impacts of Mutations
The human genetic code is fully mapped out, providing scientists with a blueprint of the DNA to identify genomic regions and their variations responsible for diseases. Traditional statistical tools effectively pinpoint these genetic "needles in the haystack," yet they face challenges in understanding how many genes contribute to diseases, as seen in diabetes or schizophrenia.

Superconductivity: the mystery of Fermi arcs solved
Superconductivity: the mystery of Fermi arcs solved
In certain materials, electrical charge can only move in very specific directions. Researchers at TU Wien (Vienna) have now shown that this can be explained by magnetic effects. High-temperature superconductivity is one of the great mysteries of modern physics: some materials conduct electrical current without any resistance - but only at very low temperatures.

Lyme borreliosis: New approach for developing targeted therapy
Lyme borreliosis is the most common tick-borne infectious disease in Europe. Up to 70,000 new cases are estimated each year in Austria alone. The bacterial infection can cause lasting health problems for patients. A MedUni Vienna research team has made significant progress in understanding the mechanism of infection and identified a potential way forward for the development of targeted therapies that do not rely on antibiotics.

Common Food Supplement could unlock cancer secret
A study on an essential mineral abundant in brazil nuts could unlock the key to preventing the spread of triple negative breast cancer, according to new research funded by Cancer Research UK. Limiting the antioxidant effects of selenium, a popular ingredient of multivitamin supplements found in everyday foods such as meat, mushrooms and cereals, could be the secret to controlling this form of the disease.

How fast is quantum entanglement?
How fast is quantum entanglement?
The emergence of quantum entanglement is one of the fastest processes in nature. Scientists at TU Wien (Vienna) show that using special tricks, this can be investigated on an attosecond scale. Quantum theory describes events that take place on extremely short time scales. In the past, such events were regarded as 'momentary' or 'instantaneous': An electron orbits the nucleus of an atom - in the next moment it is suddenly ripped out by a flash of light.

Innovative new surgical method for treating obstructive defecation disorder successfully performed for the first time
A new surgical method for treating obstructive defecation disorder has been introduced at the Department of General Surgery at MedUni Vienna and University Hospital Vienna. The procedure does not require the insertion of a foreign body and, for the first time, is minimally invasive. The new method was used for the first time worldwide at University Hospital Vienna and MedUni Vienna and offers those affected by this defecation disorder an advantageous alternative to existing therapies.

Recognizing the strengths of socio-economically disadvantaged students leads to better grades
Long-term experiment shows that social narratives have an influence on performance In their new study, psychologist Christina Bauer from the University of Vienna and her international team show the influence societal narratives can have on students' self-image and their performance. The researchers presented reverse narratives to socio-economically disadvantaged students: instead of portraying them as weak, they emphasized their strengths.

Catching prey with grappling hooks and cannons
Catching prey with grappling hooks and cannons
Predatory marine bacterium could be used in medicine Researchers at ETH Zurich, in collaboration with microbiologists from the University of Vienna, have studied the unusual arsenal of weapons of a predatory marine bacterium called Aureispira down to the smallest detail. Among other things, it is a kind of "molecular grappling hook" that catches prey.

Chickpeas - sustainable and climate-friendly foods of the future
Study shows: Chickpeas are a drought-resistant legume plant with a high protein content Climate change has a negative impact on food security. An international research team led by Wolfram Weckwerth from the University of Vienna has now conducted a study to investigate the natural variation of different chickpea genotypes and their resistance to drought stress.

The Neutron Lifetime Problem - and its Possible Solution
The Neutron Lifetime Problem - and its Possible Solution
How long do neutrons live? Different measurement results contradict each other. A possible explanation has now been proposed at TU Wien (Vienna). Neutrons are among the basic building blocks of matter. As long as they are part of a stable atomic nucleus, they can stay there for arbitrary periods of time.

Study by TU Graz Shows what Kind of Work is Facilitated by Exoskeletons
Can exoskeletons make strenuous activities easier and allow people to do hard work for longer and in a healthier way? A study by TU Graz says yes, but not always. Hard physical work is not healthy for anyone in the long term. Sooner or later, many people suffer from back, joint or muscular complaints.

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.
