First high-resolution record of fossil corals shows climate change
First high-resolution record of fossil corals shows climate change
Hawaii: Environmental data from shallow-water corals provide a glimpse 500,000 years into the past During the IODP Expedition 389 "Hawaiian Drowned Reefs" off the coast of Hawaii, scientists recovered a total of 426 meters of cores from the seafloor in water depths ranging from 130 to 1240 meters.

Baleen whales evolved a unique larynx to communicate
Baleen whales evolved a unique larynx to communicate
The new results also make it clear that human noise in the oceans severely restricts the animals The iconic baleen whales, such as the blue, gray and humpback whale, depend on sound for communication in the vast marine environment where they live. However, ever since whale song were first discovered more than 50 years ago, it remained unknown how baleen whales produce their complex vocalizations - until now.

Key cells in chronic sarcoidosis uncovered
The latest research findings from MedUni Vienna provide insights into the molecular mechanisms underlying chronic sarcoidosis, a complex granulomatous disease with limited treatment options. The scientific team, led by Thomas Weichhart and Georg Stary, presents new findings that challenge the conventional understanding of the disease and proposes a new therapeutic approach.

Quantum entanglement defies weightlessness
Quantum entanglement defies weightlessness
The ÖAW and TU Vienna were able to show during a parabolic flight: A change in gravity has no influence on quantum experiments . A team from the Austrian Academy of Sciences and the Vienna University of Technology was able to prove this during a flight with the European Space Agency: Quantum entanglement also works when the strength of gravity changes.

Spintronics: the electronics of the future could be antiferromagnetic
Spintronics: the electronics of the future could be antiferromagnetic
It is an important step forward in spintronics: the magnetic state of certain materials can be switched using surface induced strain. All our electronics are based on electrical charges being transported from one place to another. Electrons move, current flows, signals are transmitted by applying an electrical voltage.

Chronic fatigue syndrome: number of patients is expected to double due to long-term effects of the COVID-19 pandemic
Up to 80,000 people in Austria are estimated to suffer from chronic fatigue syndrome, also known as ME/CFS or myalgic encephalomyelitis/chronic fatigue syndrome. The number of ME/CFS patients is expected to rise drastically due to long-term effects of the COVID-19 pandemic. However, research in the field has neither identified mechanisms of disease onset nor causal treatment approaches.

Neuronal Insights: Flash and Freeze-Fracture
Neuronal Insights: Flash and Freeze-Fracture
ISTA researchers analyze brain region using light flashes, high-pressure freezing and fracturing Fear and addiction exert significant influence within society. Managing them is often challenging, as they are driven by intricate neuronal circuits in our brains. Understanding the underlying molecular mechanisms is crucial to intervene when these processes malfunction.

New treatment option for heart valve insufficiency
Severe heart disease or pulmonary hypertension often lead to a leak in the tricuspid valve, the valve between the right atrium and the right ventricle. However, tricuspid regurgitation can also occur without a clearly identifiable cause. In the past, this leakage was mainly treated with medication using diuretics and, for some years now, with clips inserted into the heart valve.

Artificial Intelligence as a Tool in Science
ISTA researchers welcome AI use in science, but remain cautious From identifying complex morphologies in the brain to analyzing the properties of storm clouds, artificial intelligence (AI) algorithms are aiding several research projects employing deep learning and machine learning at the Institute of Science and Technology Austria (ISTA).

Artificial cartilage with the help of 3D printing
Artificial cartilage with the help of 3D printing
A new approach to producing artificial tissue has been developed at TU Wien: Cells are grown in microstructures created in a 3D printer. Is it possible to grow tissue in the laboratory, for example to replace injured cartilage? At TU Wien (Vienna), an important step has now been taken towards creating replacement tissue in the lab - using a technique that differs significantly from other methods used around the world.

Nature is particularly beneficial for people on lower income
Nature is particularly beneficial for people on lower income
Regular time spent in nature is more beneficial to the well-being of poorer than richer people Data from a representative sample of the Austrian population suggests that the relationship between nature contact and well-being is consistently stronger for people on lower than higher incomes. However, this pattern was only found when people actively visited nature and not when they merely lived near greenspaces.

New findings shed light on the role of platelets in patients with cirrhosis
Next to other complications, cirrhosis is also linked to abnormalities in haemostasis. However, the role of alterations in platelet function had previously been insufficiently investigated. Now, researchers at the Medical University of Vienna have shed light on the connection between platelet function and the risk of bleeding, thrombosis or the occurrence of complications of cirrhosis.

How do I make my research performance visible?
The visibility of your research is in your own hands. Michaela Zottler from the TU Graz library provides valuable tips. Why is the visibility of research performances important? The impact of research performance is primarily determined by the quality of the research, but also by whether and how research achievements and the researcher are perceived.

Exact mechanism of serotonin transport in nerve cells researched
Drugs known as antidepressants target the serotonin transporter in nerve cells and are among the most commonly prescribed medicines worldwide, but are sometimes associated with significant side effects. As part of a study, a research group led by Thomas Stockner from MedUni Vienna identified the basic principles of serotonin transport and thus created a possible basis for the development of novel drugs with improved selectivity and with fewer undesirable effects.

Down to the Core of Poxviruses
ISTA researchers uncover the architecture of poxvirus cores A recent re-emergence and outbreak of Mpox brought poxviruses back as a public health threat, underlining an important knowledge gap at their core. Now, a team of researchers from the Institute of Science and Technology Austria (ISTA) lifted the mysteries of poxviral core architecture by combining various cryo-electron microscopy techniques with molecular modeling.

Improving cancer prevention among people experiencing homelessness
While people experiencing homelessness are more exposed to cancer-associated risk factors, there is a lack of awareness and structures for targeted cancer prevention. Yet people experiencing homelessness are twice as likely to be affected by cancer as people who are resident. Against this backdrop, an international team led by Igor Grabovac and Maren Jeleff from MedUni Vienna's Center for Public Health has systematically assessed the health challenges of this population group for the first time in order to create a scientifically sound basis for the development of preventive measures.

Coronary Stents: Acute inflammation triples the risk of thrombosis
Coronary Stents: Acute inflammation triples the risk of thrombosis
Coronary stents are implanted in more than 26,000 patients in Austria every year to treat angina pectoris or heart attacks. These are vascular stents made of metal that help to keep narrowed vessels open for many years. Acute clot formation (thrombosis) is the most feared complication of these procedures.
