Bats get back home to roost
Bats get back home to roost
Bats fly back to their roosts in a "leap frogging" motion ensuring they can stay out as long as possible foraging for food, researchers have found. The team from Cardiff University and the University of Sussex, developed a model from trajectory data on greater horseshoe bats - one of 18 species in the UK - to better understand how they move and engage with their environment.

Climate change threatens global forest carbon sequestration
Study: Climate change determines the sign of productivity trends in US forests (DOI: 10.1073/pnas. Climate change is reshaping forests differently across the United States, according to a new analysis of U.S. Forest Service data. With rising temperatures, escalating droughts, wildfires and disease outbreaks taking a toll on trees, researchers warn that forests across the American West are bearing the brunt of the consequences.

Capturing greenhouse gases with the help of light
Capturing greenhouse gases with the help of light
Researchers at ETH Zurich are developing a new method to remove CO2 from the atmosphere. It involves molecules that become acidic when exposed to light. Their new process requires much less energy than conventional technologies. If we want to slow down global warming, we need to drastically reduce greenhouse gas emissions.

A novel methodology used in deserts confirms that the beaches in the south of Valencia lost 70% of their surface in the last 30 years
A novel methodology used in deserts confirms that the beaches in the south of Valencia lost 70% of their surface in the last 30 years
Researchers from the Cavanilles Institute of the University of Valencia (UV) reveal in an article published in the journal Urban Science that the surface area of three beaches south of the port of València (Pinedo, El Saler and La Garrofera) has increased from 170 hectares of sand in the decade of the 90s to 43 in 2022.

Researchers’ tool to be part of European Space Agency’s Climate Change Initiative
New machine learning model predicts lake ice conditions with 94 per cent accuracy To advance climate change monitoring and public safety, researchers at the University of Waterloo have developed new tools that bring an unprecedented level of accuracy to identifying lake ice conditions. The researchers are the first to use machine learning models for processing satellite radar altimetry data that can identify between open water, thin ice, growing ice, or melting ice with 94 per cent accuracy.

Biomaterials contribute substantially to a reduction in greenhouse gas emissions but are not yet climate neutral
Biomaterials contribute substantially to a reduction in greenhouse gas emissions but are not yet climate neutral
On average, bio-based products emit 45% less greenhouse gas emissions than the fossil materials they replace, according to research conducted by Radboud University, published in Nature Communications. At the same time, there is a large variation between individual bio-based products and more efforts are required to achieve climate neutrality.

Red deer populations in Europe: more influenced by humans than by wolves and other predators
Red deer populations in Europe: more influenced by humans than by wolves and other predators
An international study shows that human hunting and land use have a decisive influence on red deer density in Europe. Red deer density is only reduced when wolves, lynx and bears co-occur at the same site. Research findings shed new light on the wolf's return to Central Europe. Alongside the occasional bison and elk, red deer are Europe's largest native wild animal.

Scientists name the commonest tropical tree species for the first time
Scientists name the commonest tropical tree species for the first time
A major international collaboration of 356 scientists led by UCL researchers has found almost identical patterns of tree diversity across the world's tropical forests. The study of over one million trees across 1,568 locations, published in Nature , found that just 2.2% of tree species make up 50% of the total number of trees in tropical forests across Africa, the Amazon, and Southeast Asia.

New dimension of the genome discovered
Distantly related organisms that live in extreme temperatures and pH conditions develop similar DNA It has long been thought that an organism's DNA provides clues only about its ancestry and how the various forms of life on Earth are related - the more similar their DNA, the more closely the species are related.

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.

Biodiversity-friendly livestock farms: a source of inspiration for the future
Biodiversity-friendly livestock farms could be a real source of inspiration! Some positive news for the planet drawn from the conclusions of a study revealing how farm design and management can provide a window of opportunity for nature. Results published in the January 2024 issue of Agricultural Systems.

Many devastating extremes in 2023 were amplified by global warming
2023 was an extraordinary year for climate: each month from June onward was warmer than the corresponding month in any previous year. In this last half year temperatures exceeded 1.5°C above pre-industrial levels (1850-1900), with some days even exceeding 2.0°C. Throughout the year, extreme weather hit nations around the world including heatwaves, droughts, floods and wildfires.

This is how Professor René Janssen paves the way to better solar cells
A professor at TU/e and colleagues have found a way to improve perovskite solar cells. An electric car, heat pump, or robotic lawn mower: the world is electrifying, and so more and more roofs are full of solar panels. The Netherlands is even among the European leaders when it comes to generating solar energy.

Communicating about climate change more effective when stories about those displaced hit ’close to home’
Study: Effects of communicating the rise of climate migration on public perceptions of climate change and migration Concern for climate change grows-along with support for policies to reduce emissions-when people read about Americans being forced to move within the U.S. because of it. That's in sharp contrast to learning about climate-induced moves to the U.S. by non-Americans, which doesn't move the dial on climate change beliefs or policy support.

When water becomes scarce, its quality often deteriorates
When water becomes scarce, its quality often deteriorates
Droughts and heat waves cause great economic damage. To reduce water scarcity, hydrologist Michelle van Vliet advocates a better understanding of the interaction between water quality and water use. Water scarcity is more than just a physical lack of water. Growing water scarcity has three causes: decreasing water availability, increasing water use and deteriorating water quality, making it unsuitable for certain uses or functions.

Building more to reduce emissions
The construction industry as a CO2 sink? Researchers at Empa's Concrete & Asphalt lab are working on this. By incorporating biochar into concrete, they are exploring the potential of CO2-neutral or even CO2-negative concrete. For optimal applicability, they process the biochar into pellets and use them to replace conventional aggregates.

How traditional cultures use their environment to navigate
How traditional cultures use their environment to navigate
Traditional navigation techniques from across the world, some of which have been in use for thousands of years, can inform western science, according to research from UCL and the University of York. The new review paper, published in Trends in Cognitive Sciences , sheds new light on remarkable feats of navigation from cultures ranging from sailors in the Marshall Islands using wave patterns to navigate the vast Pacific Ocean, to indigenous communities in Alaska using stars to find their way across the Yukon.
