A research team has proposed new understandings of the poisoning effect of carbon deposition during carbon dioxide reduction reaction (CO2RR) on the active sites of Cu electrode. The study was published in Precision Chemistry.

Despite the pervasive public interest in animal welfare, the framing of animal rights activism in the media has largely contributed to its depoliticization, argues a paper in Polity. "Vegans and "Green-Collared Criminals,'" by Serrin Rutledge-Prior, presents the reaction to a day of animal rights protests in cities and towns around Australia in 2019, and ultimately concludes that the public narratives about the activists delegitimized their endeavors.

In a development that could advance the 3D printing industry, researchers at the University of Louisville have discovered a way to transform a significant waste output from soy biodiesel plants into a valuable resource.

Within the Biodiversity Community Integrated Knowledge Library (BiCIKL) project, 14 European institutions from ten countries, spent the last three years elaborating on services and high-tech digital tools, in order to improve the findability, accessibility, interoperability and reusability (FAIR-ness) of various types of data about the world's biodiversity. These types of data include peer-reviewed scientific literature, occurrence records, natural history collections, DNA data and more.

Although plastic allows food to be packaged safely and hygienically, its extensive use constitutes a significant environmental challenge due to its limited recyclability and short shelf life. Thus, industry and the scientific community have been looking for more sustainable alternatives for decades.

Precipitation deeply couples with nutrient cycling through its interactions with atmospheric deposition and canopy interception, which alters its own chemical properties. Throughfall and stemflow carry numerous elements into the soil, not only affecting the structure of soil microbial communities, individual plant survival, and plant community succession, but also regulating ecosystem structure and function. This constitutes a key ecological process that connects the atmosphere, phyllosphere, and rhizosphere.

Alloying is a key process in creating new materials. By combining metals with desirable traits, scientists can produce alloys with suitable properties. For example, stainless steel, formed by combining iron with chromium, nickel, and other elements in smaller quantities is highly resistant to corrosion.

Less than a hundred kilos of human weight, more than two metric tons of steel: individual road transport is a huge climate killer, and switching to electric vehicles is only part of the solution because manufacturing the vehicles also causes emissions.

Despite its promising characteristics in condensed matter physics, the triply-degenerate semimetal PtBi2 has been largely unexplored in practical applications, particularly in semiconductor technology. The main difficulties include a lack of empirical data on the integration of PtBi2 with existing semiconductor components and the need for innovative approaches to leverage its unique properties, such as high stability and mobility, within the constraints of current electronic manufacturing processes.

In a significant stride towards understanding climate change, a recent study published in the International Journal of Climatology has successfully homogenized and analyzed over a century's worth of daily temperature data from the Beijing Observatory (BO), spanning from 1915 to 2021.

Rapid growth in global energy demand has caused massive depletion of traditional fossil fuels and serious environmental problems, and there is no doubt that the development of efficient energy storage and conversion technologies is an essential field of research. Rechargeable Zn-air batteries have attracted great research interest due to their high energy density, low cost, environmental friendliness, and safety.

The latest edition of Florida Atlantic University's "Florida Climate Resilience Survey," found that 90% of Floridians believe that climate change is happening. In comparison, a recent Yale University survey showed 72% of all Americans believe climate change is happening. The FAU survey includes questions on beliefs about climate change, experience with extreme weather events and support for climate-related policies.

A research team led by Prof. Zeng Jie and Prof Geng Zhigang from University of Science and Technology of China (USTC) has proposed a new model for sustainable hydroxylamine (NH2OH) synthesis via a plasma-electrochemical cascade pathway (PECP). They achieved the green and sustainable synthesis of NH2OH from ambient air and water at mild conditions. Their study is published in Nature Sustainability.

Robots revolutionized the manufacturing industry by automating assembly lines. Now, more and more, they are being used to expedite the pace of scientific discovery.

Raquel Hernando, a Juan de la Cierva researcher associated with the European project TIED2TEETH, at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH), is the lead author of a paper published in the American Journal of Biological Anthropology, in which the teeth of 84 adult individuals found at eight sites in the northeast Iberian Peninsula were analyzed to offer new perspectives on the diet of these populations in recent prehistory.

When an East Texas cattle operation contacted Texas A&M AgriLife Extension Service cattle specialists in the Texas A&M College of Agriculture and Life Sciences Department of Animal Science after experiencing a rash of neurological, unknown issues with their calves, it started a seven-year search for answers.

A new study from the University of Hawaiʻi at Mānoa shows that chlorine mixed with petroleum in water can potentially produce inadvertent byproducts harmful to human health. The research is published in the journal Chemosphere.

The first crewed launch of Boeing's Starliner spaceship to the International Space Station has been postponed again due to a technical snafu, the company said Tuesday.

Pathogens are nothing if not adaptable, and their ability to protect themselves against antibiotics increasingly poses a public health concern. A research team led by Los Alamos National Laboratory has used machine learning, an application of artificial intelligence, to identify molecular properties that could guide the discovery of new types of antibiotics, especially among pathogens deemed critical by the World Health Organization due to their high bacterial resistance.

An unusual boost in plant productivity can foreshadow severe soil water loss, and NASA satellites are following the clues.

Researchers at Macquarie University have found a significant portion of shark meat sold in Australian fish markets and takeaway shops is mislabeled, including several samples from threatened species.

Climate researchers often emphasize the fact that reducing carbon emissions is in everyone's best interest, and should involve all of us. But how good are they at minimizing their own carbon footprint?

When the ice sheet in Greenland melts, as it has done increasingly in recent years, the bedrock beneath moves slightly.

Bacteria and fungi live together on the surface of plant roots, which can promote symbiotic interactions with the plant. Plant roots that are especially fine can support various niches for their microbial proliferations, but traditionally, microbiome studies have not examined fine root systems separately from the rhizosphere.

University of Cincinnati ornithologist Ron Canterbury displayed dozens of birds that died from striking glass windows in the city.
