Urbanization increases seasonal differences in plant-pollinator networks
Urbanization increases seasonal differences in plant-pollinator networks
Research team led by Göttingen University investigates importance of season and environment in tropical megacity Increasing urbanization worldwide is a growing threat to biodiversity. At the same time, flowering plants are often more diverse in cities than in the countryside. This is due to flowering plants and agricultural crops, which are increasingly being grown in cities.

Companies are missing their climate goals with misaligned behaviour
The emissions pathways of most companies in high-emitting sectors are not aligned with the climate targets of the Paris Agreement. To better contribute to national and global sustainability efforts, corporate behaviour must change. This is the main message of a new study by Imperial College Business School published in Nature Communications.

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.

The ocean may be storing more carbon than estimated in earlier studies
The ocean may be storing more carbon than estimated in earlier studies
The ocean's capacity to store atmospheric carbon dioxide is some 20% greater than the estimates contained in the latest IPCC report 1 . These are the findings of a study to be published in the journal Nature on December 6, 2023, led by an international team including a biologist from the CNRS 2 . The scientists looked at the role played by plankton in the natural transport of carbon from surface waters down to the seabed.

Seabird droppings help tropical coral reefs facing climate change threat
Seabird droppings help tropical coral reefs facing climate change threat
A new study, by an international team of scientists, has found the presence of seabirds on islands near to tropical reefs helps corals to 'bounce back' much quicker from bleaching events. Bleaching can cause mass die off of corals when seas are too hot. The research, led by Lancaster University, with support from the University of Southampton, shows that this accelerated recovery is a result of faster coral growth near seabird colonies.

Using AI to find microplastics
Using AI to find microplastics
Researchers use AI to identify toxic substances in wastewater with greater accuracy and speed An interdisciplinary research team from the University of Waterloo is using artificial intelligence (AI) to identify microplastics faster and more accurately than ever before. Microplastics are commonly found in food and are dangerous pollutants that cause severe environmental damage - finding them is the key to getting rid of them.

An Unexpected Discovery at the Air-Water Interface
Ocean acidification, mammal respiration, and aerosol formation all depend on chemistry that occurs at air-water interfaces. In new research, scientists from the Department of Energy's Lawrence Berkeley National Laboratory ÜBerkeley Lab) have discovered which pathway carbon dioxide (CO2) molecules follow on their way from the atmosphere into water - and it's not the one that they expected.

Recycling packaging materials: Chemist wants to use plastics sustainably
Recycling packaging materials: Chemist wants to use plastics sustainably
Simple plastics made from polyolefins such as films or carrier bags have become an integral part of our everyday lives, but are rarely recycled. Junior Professor Robert Geitner wants to give these food packaging materials a new lease of life. At his Physical Chemistry/Catalysis Group, he is researching new potential applications for the materials.

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.

Transforming CO2 into valuable products
Waterloo research team partners with BMO to turn pollution into renewable energy  By Nicola Kelly Faculty of Engineering An interdisciplinary research team from the University of Waterloo aims to tackle CO2 emissions in the value chain by transforming CO2 into valuable chemicals needed by industry. Supported by BMO, the research focuses on the use of green hydrogen to capture CO2 from power plants as well as the iron, steel, and cement industries, and convert it into useful gases via reverse water gas shift reaction.

Unlocking the secrets of natural materials
Professor Benedetto Marelli develops silk-based technologies with uses "from lab to fork," including helping crops grow and preserving perishable foods. Growing up in Milan, Benedetto Marelli liked figuring out how things worked. He repaired broken devices simply to have the opportunity to take them apart and put them together again.

Uncovering the genetic history of British otters
Uncovering the genetic history of British otters
New genetic research has revealed how British otters were able to recover from species loss in the 1950s with the help of their counterparts from Asia. Using genome sequencing data, a team from Cardiff University's Otter Project showed that much of the genetic diversity of British otters was lost when chemical pollution led to severe population declines in the 1950-1970s.

An international collaboration identifies new genes influencing beef production
Beef currently accounts for 21% of the world's meat consumption, placing it third after poultry and pork. It therefore plays a crucial role in the global food system, with great economic and cultural importance in many countries. However, its production has a high environmental impact, mainly due to greenhouse gas emissions that contribute to climate change.

Researchers sound out Canadian military's plan to combat ocean noise pollution
Researchers sound out Canadian military’s plan to combat ocean noise pollution
A new study from Simon Fraser researchers examines the Canadian military's efforts to reduce the impacts of underwater noise pollution on species during training exercises in the Pacific Ocean but caveat that more can still be done. The paper, published today in Marine Policy , takes aim at a report commissioned by the Canadian Department of National Defence (DND) to reduce the effects of noise pollution from military small-arms munitions training within "Whiskey Hotel", a 330-square-kilometre area in the Strait of Juan de Fuca off the British Columbia coast.
