A self-cleaning wall paint
A self-cleaning wall paint
A breakthrough in catalysis research leads to a new wall paint that cleans itself when exposed to sunlight and chemically breaks down air pollutants. Typically, beautiful white wall paint does not stay beautiful and white forever. Often, various substances from the air accumulate on its surface. This can be a desired effect because it makes the air cleaner for a while - but over time, the colour changes and needs to be renewed.

Cervical cancer: immunotherapy proven to improve prognosis
Cervical cancer: immunotherapy proven to improve prognosis
Since 1999, the standard treatment for locally advanced cervical cancer has consisted of external radiotherapy followed by chemotherapy and brachytherapy. As the prognosis for patients is still poor in many cases despite these measures, intensive research is being conducted into new options. In a large-scale clinical trial, an international team involving MedUni Vienna has shown that the immunotherapeutic agent pembrolizumab in combination with chemoradiotherapy leads to a statistically significant improvement compared to chemoradiotherapy alone.

New Method for Analysing Nanoporous Materials
New Method for Analysing Nanoporous Materials
Using only a single electron microscope image, researchers at TU Graz can determine the type and exact position of so-called guest atoms in high-tech materials. They also come closer to solving the mystery of the blue colour of aquamarine. In addition to their main components, the properties of crystalline and nanoporous materials often depend crucially on guest atoms or ions that are embedded in the tiny pores of their lattice structure.

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".
