How soil microbes survive in harsh desert environments
How soil microbes survive in harsh desert environments
As desertification spreads worldwide, scientists discover how desert microbes endure harsh drought periods Prolonged droughts followed by sudden bursts of rainfall - how do desert soil bacteria manage to survive such harsh conditions? This long-debated question has now been answered by an ERC project led by microbiologist Dagmar Woebken from the Centre for Microbiology and Environmental Systems Science (CeMESS) at the University of Vienna.

Novel UV Broadband Spectrometer Revolutionises Air Pollutant Analysis
Novel UV Broadband Spectrometer Revolutionises Air Pollutant Analysis
The laser-based technology developed at TU Graz enables the continual real-time analysis of air pollutants and their interaction with other gases and sunlight. Sunlight has a major influence on chemical processes. Its high-energy UV radiation in particular is strongly absorbed by all materials and triggers photochemical reactions of the substances present in the air.

How Plants Heal Wounds
How Plants Heal Wounds
April 4, 2024 Pressure changes and mechanical forces trigger wound healing in plants Plants are very robust and survive harsh environments, owing in part to their remarkably efficient wound-healing capacity. For over a century, scientists aimed to understand it in more detail. A new collaborative study at the Institute of Science and Technology Austria (ISTA) now shows that the process is quite straightforward, revolving around pressure and forces.

Rays were more diverse 150 million years ago than previously thought
New fossil ray species discovered in Bavarica, Germany: Aellopobatis bavarica from the Late Jurassic In a new study recently published in the journal Papers in Palaeontology , an international team of scientists led by palaeobiologist Julia Türtscher from the University of Vienna has explored the puzzling world of rays that lived 150 million years ago and discovered a previously hidden diversity - including a new ray species.

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".

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.

Global warming increases the diversity of active soil bacteria
Global warming increases the diversity of active soil bacteria
New findings enable more accurate prediction of the carbon cycle Warmer soils harbour a greater diversity of active microbes, according to a new study from researchers at the Centre for Microbiology and Environmental Systems Science (CeMESS) at the University of Vienna. The study, published in Science Advances , represents a significant shift in our understanding of how microbial activity in the soil influences the global carbon cycle and possible feedback mechanisms on the climate.

Cloud Clustering Causes More Extreme Rain
Cloud Clustering Causes More Extreme Rain
New climate model shows more extreme rainfall in the tropics with increased temperatures Understanding cloud patterns in our changing climate is essential to making accurate predictions about their impact on society and nature. Scientists at the Institute of Science and Technology Austria (ISTA) and the Max Planck Institute for Meteorology published a new study in the journal Science Advances that uses a high-resolution global climate model to understand how the clustering of clouds and storms impacts rainfall extremes in the tropics.

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.

Shape matters: How microplastic travels that far
Shape matters: How microplastic travels that far
New study: Microplastic fibers are settling substantially slower than spherical particles in the atmosphere and might even reach stratosphere How far microplastics travel in the atmosphere depends crucially on particle shape, according to a recent study by scientists at the University of Vienna and the Max Planck Institute for Dynamics and Self-Organisation in Göttingen: While spherical particles settle quickly, microplastic fibers might travel as far as the stratosphere.

Prin­ting inks made from plants
On the path to a circular economy, Judith Deriu is developing natural color pigments from plants and uses them to make sustainable printing inks for industry in the laboratory at the Research Institute of Textile Chemistry and Textile Physics in Dornbirn. Natural dyes have been used by humans for centuries.

2023: A Year of Research Successes at TU Graz
At Graz University of Technology (TU Graz) in 2023, important discoveries were made, new insights gained and exciting information gleaned. An end-of-year review. TU Graz in Space In 2013, the small satellite TUGSAT-1 was Austria's first satellite in space. It was built at TU Graz and has been observing the earth from low earth orbit ever since.

Revolutionary advances in CO2 utilization technology
Revolutionary advances in CO2 utilization technology
Converting the climate-damaging CO2 into usable substances could offer an important approach to tackling the climate crisis. Promising methods have already been developed at the Johannes Kepler University Linz. A new discovery now brings industrial use within reach. Using special catalysts, Assoc. Prof. Wolfgang Schöfberger (JKU Institute of Organic Chemistry) developed a method years ago on a laboratory scale to convert CO2 into industrial alcohol.

Less waste thanks to mechanochemistry
"Chemistry is when it smokes and stinks" is an old saying. But green chemistry shows that things can be done differently . Green chemistry has been firmly established in research at TU Wien for more than a decade. With the inter-university Master's in Green Chemistry, it is now also gaining visibility in teaching.

Elastane recycling: Stretching the lifespan of textiles
Elastane recycling: Stretching the lifespan of textiles
Pleasant to wear, extremely unpleasant to recycle: elastane makes it difficult to reuse textiles. A solution has been found at TU Wien. Clothing is far too valuable to simply dispose of and burn. Starting in 2025, used textiles are to be collected and recycled throughout the EU. Improved recycling processes are urgently needed to deal with the huge amount of textiles that will then be produced in an efficient and environmentally friendly way.

Perception of sustainability and food health are closely linked
Perception of sustainability and food health are closely linked
Many people want to eat healthily, but also value the sustainability of their food . Intuitively, healthy is often equated with sustainable. A study by scientists from the Johannes Kepler University Linz, the University of Constance and the Hamburg University of Applied Sciences has investigated whether this perception corresponds to reality.
