Prin­ting inks made from plants
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.

’Maintain Asian forest diversity to avoid climate change impact’
Research suggests that conservation of Asian forests now can help resist impacts from climate change. A team of international scientists led by Dr Rebecca Hamilton at the University of Sydney has found that rather than dry savannah in South East Asia dominating during the Last Glacial Maximum more than 19,000 years ago, there was a mosaic of diverse closed and open forest types, upending previous scientific consensus.

Novel Catalyst System for CO2 Conversion
Novel Catalyst System for CO2 Conversion
Novel Catalyst System for CO2 Conversion Researchers are constantly pushing the limits of technology by breaking new ground in CO2 conversion. Their goal is to turn the harmful greenhouse gas into a valuable resource. Research groups around the world are developing technologies to convert carbon dioxide (CO2) into raw materials for industrial applications.

A long-known deposit yields new secrets
A long-known deposit yields new secrets
Paleontologists lack the fossils they need to trace the evolutionary history of the Amazon region, a region characterized by unparalleled biodiversity. By exploiting data from a site known for over a century, Juan Carrillo, a researcher at the University of Fribourg, and his colleagues from other institutions, have made exceptional discoveries that shed new light on this little-known past .

Wolves of Northern Quebec: from sedentary to migratory
The Northern Québec caribou is the longest migrating land mammal in North America. The wolf is literally right behind it. If Santa's reindeer share the misfortune of migrating caribou in northern Quebec, there's a good chance they'll have a pack of wolves on their heels during their December 25 jaunt.

Common insect species are suffering the biggest losses
Common insect species are suffering the biggest losses
Small Tortoiseshell butterflies (Aglais urticae) are an example of a species with formerly high local abundances that has declined in number. Insect decline is being driven by losses among the locally more common species, according to a new study published in "Nature".

Permafrost: a ticking time bomb beneath our feet
Permafrost: a ticking time bomb beneath our feet
Nearly a quarter of the Earth's land surface is permanently frozen. These areas, known as permafrost, are found in northern polar regions and at high altitudes.

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.

Satellite analysis of rivers could provide improved flood warnings
A new way to monitor the flow of rivers from satellites could provide a valuable early warning system for flood risk. A new way to monitor the flow of rivers from satellites could provide a valuable early warning system for flood risk, scientists say. University of Glasgow researchers have developed the first method of measuring the speed of river flows by analysing video footage captured from orbit.

The Colour of Dragonflies Changes throughout the Year
The Colour of Dragonflies Changes throughout the Year
The colour of dragonfly communities reacts to seasonal variation in solar radiation. Over the last 30 years, however, this colour pattern has changed - probably as a result of climate change. In a new study, researchers at Julius-Maximilians-Universität Würzburg (JMU) in Bavaria, Germany, have discovered that the colour of dragonfly communities reacts to seasonal fluctuations in solar radiation.

Toxic chemicals found in oil spills and wildfire smoke detected in killer whales
Toxic chemicals found in oil spills and wildfire smoke detected in killer whales
Toxic chemicals produced from oil emissions and wildfire smoke have been found in muscle and liver samples from Southern Resident killer whales and Bigg's killer whales. A study published today in Scientific Reports is the first to find polycyclic aromatic hydrocarbons (PAHs) in orcas off the coast of B.C., as well as in utero transfer of the chemicals from mother to fetus.

Human activity responsible for mass bird extinctions
Humans have wiped out around 1,400 bird species - twice as many as previously thought - with major implications for the ongoing biodiversity crisis, a new study involving UCL researchers has found. Many of the world's islands were previously untouched paradises, but the arrival of people to places like Hawaii, Tonga and the Azores led to far-reaching impacts including deforestation, overhunting and the introduction of invasive species.

How will climate change affect how predators hunt prey? Two UW professors teamed up to find out
How will climate change affect how predators hunt prey? Two UW professors teamed up to find out
As climate change warms the planet, weather patterns are likely to shift. Even the consistency of snow - how fluffy it is, for example - could change. Laura Prugh , a wildlife ecologist and University of Washington associate professor in the School of Environmental & Forest Sciences, wants to know how these changing conditions will affect how predators hunt prey.

Utrecht University's Earth Sciences for the First Time Ever in the Guinness Book of World Records
Utrecht University’s Earth Sciences for the First Time Ever in the Guinness Book of World Records
For the first time ever, research led by one of Utrecht University's earth scientists - Dr  Dan Palcu - has earned a place in the Guinness Book of World Records. His fascinating research shows the immense proportions of the largest lake the Earth has ever seen: the Paratethys. Guinness World Records published a whole page about the 'Largest lake ever' on their website, as well as a highlight in the print edition.

Artificial Intelligence shows that socioeconomic level conditions migrations due to environmental catastrophes
An article from the Image and Signal Processing (ISP) research group of the University of Valencia (UV), led by Gustau Camps-Valls and which has used Artificial Intelligence (AI) as a tool, concludes that the socioeconomic level explains the population movements that occur after catastrophes generated by extreme natural phenomena such as floods, windstorms and landslides.

Biofuels and Carbon Crops Take Flight
Every year, airplanes crisscrossing U.S. skies burn 23 billion gallons of fuel, leaving contrails and 8% of the nation's transportation-related greenhouse gas (GHG) emissions in their wake. A recent study by researchers from the U.S. Department of Energy's (Doe) Lawrence Berkeley National Laboratory ÜBerkeley Lab) and Sandia National Laboratories reveals which crop-based feedstocks offer the greatest potential for a plentiful, cost-competitive, renewable alternative to petroleum-based jet fuel, while also maximizing atmospheric carbon removal.

Breakthrough reveals poaching hotspots, trade routes of most trafficked endangered mammal
Key takeaways: Pangolins, endangered animals resembling a cross between an aardvark and armadillo, are illegally hunted for their scales, which are sold on the international market. UCLA researchers and partners used their knowledge of the white-bellied pangolin's genome to trace internationally traded scales back specific sites where the animals were poached.

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.

New Insights into Ecosystem Functions
New Insights into Ecosystem Functions
A DFG research group led by the University of Würzburg has developed a method that makes it possible to analyse the relationship between biodiversity within and between ecosystems and the multifunctionality of entire landscapes. Ecosystems fulfil a number of vital tasks: They store carbon, clean polluted water, pollinate plants and so on.
