“#Could recently spotted dim point sources explain the galactic center excess (GCE)?” Map of S½D. Peaks with S½D ≥ 4 in the region 2° ≤ jbj ≤ 20°; jlj ≤ 20° shown as crosses. 4FGL sources shown in red circles of size 0.3°ð1°Þ for 9 ≤ TS ≤ 49ð49 ≤ TSÞ. We find 8 sources…
“#Road traffic microplastics flooding world’s oceans: study” As global plastic production continues to surge, the study is the first attempt at quantifying how much plastic from road vehicle tyres and brake pads is dispersed and deposited by air currents Airborne microplastics from traffic pollution may be entering the world’s oceans at a similar rate to…
“#Review of progress towards advanced Lithium-sulfur batteries” Lithium-sulfur (Li-S) batteries have attracted much attention for its high energy density, low cost and environmental friendliness. However, they suffer from short life cycle, low columbic efficiency, and safety issues. Through summarizing and outlining the effective strategies to solve the above challenges, in this review, the recent progresses…
“#About 94% of wild bee and native plant species networks lost, study finds” Credit: Lilla Frerichs/public domain Climate change and an increase in disturbed bee habitats from expanding agriculture and development in northeastern North America over the last 30 years are likely responsible for a 94 per cent loss of plant-pollinator networks, York University researchers…
“#Scientists develop new method to improve police lineups” Credit: CC0 Public Domain In a discovery with important implications for criminal justice, a team of scientists from USC and other Southern California research institutions has developed a unique way to measure the reliability of an eyewitness trying to pick a culprit from a police lineup. It’s…
“#Scientists solve a durability issue in fuel cells for hydrogen cars” Credit: Pohang University of Science & Technology (POSTECH) When a bicycle gets wet in the rain, the frame and chain become corroded or rusty, which shortens the life of the bike. Oil needs to be regularly applied to prevent this from happening. Battery cells…
“#Back to the future: new study could lead to bumper crops” Using a chloroplast SynBio approach the researchers deciphered how the small subunit influences potato Rubisco catalysis. Credit: Elena Martin-Avila, et al. (2020). Research led by scientists at The Australian National University (ANU) could lead to major improvements in crop production. The study shows a…

Fong (Northwestern University)/Image processing: Travis Rector (University of Alaska Anchorage), Mahdi Zamani & Davide de Martin Rapid follow-up of the optical afterglow from one of…
“#Scientists investigate radiolabeling of calcium carbonate particles in vivo” Credit: Pixabay/CC0 Public Domain Сalcium carbonate particles are among the most promising bioactive compounds. However, before their use for drug delivery, their toxicity should be established, as well as their distribution inside laboratory animals. A team of investigators from ITMO University’s Department of Physics and Engineering…
“#Cloud computing could be producing hidden greenhouse gas emissions” Credit: Victorgrigas/Wikideia/ CC BY-SA 3.0 The amount of energy used for cloud computing, which contributes to climate change, needs to be more transparent says an Imperial researcher. Information technology (IT) services are increasingly outsourced to huge data centres, but it is not clear how much energy…
