Artificial Intelligence shows that socioeconomic level conditions migrations due to environmental catastrophes
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.

Climate change threatens a quarter of Australia's low-lying coral reef islands
Climate change threatens a quarter of Australia’s low-lying coral reef islands
University of Sydney researchers have found 25 percent of Australia's coral islands, land masses formed by reefs, currently face high to very high risk of being wiped out by climate change. The findings, published in the latest edition of the journal Science of the Total Environment , identified that all of the 56 investigated Australian coral islands are exposed to some degree of climate risk but that three small, unvegetated coral islands in Western Australia, on Scott, Clerke and Imperieuse reefs, are the most vulnerable.

Accurate snow measurement thanks to AI and satellites
Accurate snow measurement thanks to AI and satellites
Snow measurement has never been so fast and accurate: researchers have developed an artificial intelligence capable of determining snow depth across Switzerland using satellite images. How much snow is there up in the mountains, and where exactly is it? The answer is of just as much interest to the winter tourism industry and operators of hydropower plants as it is to winter sport enthusiasts looking to gauge the risk of avalanches.

Seattle metro residents near Amazon delivery stations face more pollution but order fewer packages
Seattle metro residents near Amazon delivery stations face more pollution but order fewer packages
While it is common to see Amazon Prime vans circling the city of Seattle year-round, there might be even more deliveries than usual right now, thanks to the Black Friday and Cyber Monday deals that rang in the holiday season. Researchers at the University of Washington were curious how the delivery of e-commerce products affects pollution levels across the Seattle metropolitan area, which includes Tacoma, Seattle, Bellevue and Everett.

How forests smell - a risk for the climate?
Plants emit odours for a variety of reasons, such as to communicate with each other, to deter herbivores or to respond to changing environmental conditions. An interdisciplinary team of researchers from Leipzig University, the Leibniz Institute for Tropospheric Research (TROPOS) and the German Centre for Integrative Biodiversity Research (iDiv) carried out a study to investigate how biodiversity influences the emission of these substances.

Satellite-based method measures carbon in peat bogs
The technique could enable restoration efforts and doesn't require labor-intensive onsite sampling. Peat bogs in the tropics store vast amounts of carbon, but logging, plantations, road building, and other activities have destroyed large swaths of these ecosystems in places like Indonesia and Malaysia.

Finding more sustainable ways to use plastics in agriculture
International scientists including UdeM professor Kevin Wilkinson address the worrisome problem of millions of tonnes of plastic being used on farms around the world. Every year, according to the United Nations Food and Agriculture Organization, some 12.5 million tonnes of plastic are used in agricultural production worldwide.

What’s for dinner? Paleontologist finds out through remarkable specimen
1st-ever prey found inside fossilized juvenile tyrannosaur leads to deeper understanding about feeding habits of these iconic predators The difference between a juvenile and adult tyrannosaur is massive - both figuratively and literally. While adults weighed around 3,000 kilograms, the weight of a pick-up truck, juveniles were much leaner.

Beluga whales’ calls may get drowned out by shipping noise in Alaska’s Cook Inlet
Beluga whales are highly social and vocal marine mammals. They use acoustics to navigate, find prey, avoid predators and maintain group cohesion. For Alaska's critically endangered Cook Inlet beluga population, these crucial communications may compete with a cacophony of noise from human activities. New research from the University of Washington, the National Oceanic and Atmospheric Administration's Alaska Fisheries Science Center and the Alaska Department of Fish and Game is the first to document the complex vocal repertoire of the Cook Inlet beluga whale population.

Battery recycling: China is in first place
China covers its demand for lithium, cobalt and nickel for batteries by recycling, ahead of Europe and the USA. With the increasing production of batteries for electric vehicles, the demand for the necessary raw materials is also rising. In view of the supply risks, environmental problems and precarious working conditions associated with the extraction and transportation of these raw materials, the recycling of battery materials has become an important topic in science, politics and industry.
