In a groundbreaking new study, conducted within the framework of the FWF-funded Cluster of Excellence "Microbiomes drive Planetary Health", scientists from the University of Vienna, in collaboration with the University of Southampton, Aalborg University and Boston University, have revealed that the widely prescribed Parkinson's disease drug entacapone significantly disrupts the human gut microbiome by inducing iron deficiency. The study, published in Nature Microbiology, provides new insights into the often-overlooked impact of human-targeted drugs on the microbial communities that play a critical role in human health.

Many living organisms are able to regenerate damaged or lost tissue, but why some are particularly good at this and others are not is not fully understood. Molecular biologists Alexander Stockinger, Leonie Adelmann and Florian Raible from the Max Perutz Labs at the University of Vienna have now made an important contribution to clarifying this question in a new study.

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.

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.

Predatory snails drill holes in the shells of their prey. Using these boreholes, a research team led by palaeontologist Martin Zuschin from the University of Vienna was able to create a time series of predator-prey relationships in the northern Adriatic over the past millennia. This showed that human influences led to a collapse in predator-prey relationships from the 1950s onwards.

A new study reveals the surprisingly convergent evolution in the inner ear of mammals. An international research team led by Nicole Grunstra from the University of Vienna and Anne Le Ma卯tre from the Konrad Lorenz Institute (KLI) for Evolution and Cognition Research (Klosterneuburg) showed that a group of highly divergent mammals known as Afrotheria and distantly related, but ecologically very similar mammals independently evolved similar inner ear shapes. The study has just been published in the prestigious journal Nature Communications.

Climate scientists have long agreed that humans are largely responsible for climate change. A new study, co-led by Bojana Ve膰kalov from the University of Amsterdam and Sandra Geiger from the University of Vienna, finds that communicating the scientific consensus about climate change can clear up misperceptions and strengthen beliefs about the existence and the causes of climate change. The team surveyed over 10,000 people from 27 countries on 6 continents. The study has just been published in the renowned journal Nature Human Behaviour.

In recent years, machine learning models have become increasingly popular for risk assessment of chemical compounds. However, they are often considered 'black boxes' due to their lack of transparency, leading to scepticism among toxicologists and regulatory authorities. To increase confidence in these models, researchers at the University of Vienna proposed to carefully identify the areas of chemical space where these models are weak. They developed an innovative software tool ('MolCompass') for this purpose and the results of this research approach have just been published in the prestigious Journal of Cheminformatics.

The sea anemone Nematostella vectensis is potentially immortal. Using molecular genetic methods, developmental biologists led by Ulrich Technau from the University of Vienna have now identified possible candidates for multipotent stem cells in the sea anemone for the first time. These stem cells are regulated by evolutionary highly conserved genes, which in humans are usually only active in the formation of egg and sperm cells, but give ancient animal phyla such as cnidarians a high degree of regenerative capacity to even escape ageing. The results are currently being published in Science Advances and could also provide insights into the human ageing process in the future.

An international research team led by the Centre for Microbiology and Environmental Systems Science (CeMESS) at the University of Vienna has discovered that comammox bacteria, first identified by them in 2015, can grow using guanidine, a nitrogen-rich organic compound, as their sole energy and nitrogen source.

A new study by an international team of collaborators led by researchers at the University of Vienna, and in collaboration with the Dom Museum Wien, aimed to address the questions of whether art exhibitions can make us more empathic or even change our attitudes and behaviors? The researchers were able to show that, indeed, looking through the exhibition reduced xenophobia and increased acceptance of immigration. Even more, by employing a new cellphone-based experience sampling method, they could track how long these changes last. The study was recently published in the American Psychological Association Journal Psychology of Aesthetics, Creativity, and the Arts.

"Holiday" or "vacation", "to start" or "to begin", "my friend鈥檚 cat" or "the cat of my friend" 鈥� in our language, there are different ways of expressing the same things and concepts. But can the choice of a particular variant determine whether we prefer to cooperate with certain people rather than with others?

Using two optically trapped glass nanoparticles, researchers observed a novel collective Non-Hermitian and nonlinear dynamic driven by nonreciprocal interactions. This contribution expands traditional optical levitation with tweezer arrays by incorporating the so called non-conservative interactions.

In a new study, scientists from the Max Planck Institute for Marine Microbiology, the Alfred Wegener Institute and the University of Vienna shed light on an unexpected partnership: A marine diatom and a bacterium that can account for a large share of nitrogen fixation in vast regions of the ocean. This symbiosis likely plays a key role for global marine nitrogen fixation and productivity, and thus uptake of carbon dioxide. The newly-discovered bacterial symbiont is closely related to the nitrogen-fixing Rhizobia which live in partnership with many crop plants and may also open up new avenues for engineering nitrogen-fixing plants. The results were published in the current print edition of the renowned journal Nature.

Opera singers have to use the extreme limits of their voice range. Many pedagogical and scientific sources suggest that the highest pitches reached in classical singing can only be produced with a so-called "whistle" voice register, in analogy to ultrasonic vocalizations of mice and rats.
