Cardiac amyloidosis: New AI system developed for early diagnosis
Cardiac amyloidosis is a serious disease in which abnormal proteins (amyloids) accumulate in the heart muscle and impair heart function. As the disease leads to serious complications such as heart insufficiency and, in many cases, death if left untreated, early diagnosis is essential in order to start treatment in good time.

Frequency of heat days systematically underestimated in many studies
Frequency of heat days systematically underestimated in many studies
Many studies on the climate crisis focus on researching temperature extremes on a global scale. Scientists at the University of Vienna have now uncovered an error in an established calculation method, leading to a systematic underestimation in the frequency of heat days. The error is based in the previously unnoticed impact of the seasonal cycle on the extreme threshold due to the incorrect application of so called "moving time windows".

Genetic basis for the evolution of hair discovered in the clawed frog
The development of hair was of central importance for the evolution of mammals and thus also of humans. However, the evolutionary origin of the genetic programme of hair was previously unknown. An international research team led by Leopold Eckhart from MedUni Vienna has now been able to show that important hair components and their genetic control have already evolved in amphibians.

Holographic message encoded in simple plastic
Holographic message encoded in simple plastic
Important data, such as a Bitcoin wallet address, can be stored and concealed quite easily in ordinary plastic using 3D printers and terahertz radiation, scientists at TU Wien show. There are many ways to store data - digitally, on a hard disk, or using analogue storage technology, for example as a hologram.

New paths to energy security: demand-oriented solutions
New paths to energy security: demand-oriented solutions
Energy systems that are essential to our daily lives are increasingly threatened by wars, pandemics, climate change and other unexpected events. An international team of researchers has found that demand-side approaches have far greater potential to reduce our vulnerability to energy crises than supply-side measures.

New insights could improve treatment of liver fibrosis
Repeated or chronic liver injury, for example by viral hepatitis or alcohol consumption, triggers a complicated molecular process of scaring called liver fibrosis. Researchers at CeMM and MedUni Vienna have now succeeded in better understanding this process in a new study by examining gene activities at various stages of the liver disease.

New findings on the prevention of heart attacks and strokes
New findings on the prevention of heart attacks and strokes
Blockage of arterial blood vessels caused by atherosclerosis is largely responsible for heart attacks and strokes, which are the most common causes of death worldwide. The complex mechanisms that lead to pathological changes in the arteries are not yet fully understood. An international research team led by the Medical University of Vienna and the University Hospital of Würzburg has now made important progress in understanding this disease and identified potential new approaches for early detection and therapy.

Ultra-short light pulses enable high-precision 'artificial nose'
Ultra-short light pulses enable high-precision ’artificial nose’
A new spectroscopy method has been developed at TU Wien: Using a series of laser pusles, chemical analyses can be carried out much faster and more precisely than before. Whether you want to analyze environmental samples in nature or monitor a chemical experiment, you often need highly sensitive sensors that can "sniff out" even tiny traces of a certain gas with extreme accuracy.

Can quantum computers help in the development of new drugs?
Can quantum computers help in the development of new drugs?
Scientists predict that quantum computers will be able to discover drugs faster than conventional computers in the future Quantum computers have promising potential applications. One potential area of application is computer-aided research and development of new drugs. A team from the University of Vienna, together with researchers from Boehringer Ingelheim, BASF, Google, QC Ware and the University of Toronto, have investigated the possibilities of this technology in a review article published in the journal Nature Physics .

Female doctors give high marks for working conditions in primary care centers
Female doctors generally rate the working conditions in primary care units (PCUs) highly. This is the result of a recent survey conducted by MedUni Vienna on work-life balance and satisfaction among female doctors working in primary care units. According to the study, there is a need to catch up in the areas of distribution of working hours and time for additional activities such as external teaching or further training.

New model for the early detection of diseases
In a recent study, researchers from the Complexity Science Hub and MedUni Vienna are analysing the entire health trajectory of almost nine million people in Austria for the first time. They identify critical points at which disease progression drifts apart significantly - with serious consequences for the lives of patients and for the healthcare system.

Mystery of Curling Paper Solved
Mystery of Curling Paper Solved
Paper printed on one side starts to curl with a delay of up to a few days. Researchers at TU Graz have discovered that this is due to solvents in the ink that over time migrate towards the unprinted side of the paper. Although mankind has been using paper for at least 2000 years, it still presents us with one or two mysteries.

Micro- and nanoplastics in the body are passed on during cell division
The gastrointestinal tract is already known to researchers as a major storage site for microand nanoplastic particles (MNPs) in the human body. A research consortium consisting of the University of Vienna, the Medical University of Vienna and other partners under the leadership of CBmed GmbH in Graz has now investigated the effects of the tiny plastic particles on cancer cells in the human gastrointestinal tract.
