Red deer in a forest. Credit: INRAE – Anders Mårell Temperature, rainfall, snow and extreme weather events are all factors linked to climate change that directly affect wildlife. Understanding the impact of these factors on the physiology, population dynamics and distribution of different deer species is important for monitoring and protecting them. The scientists involved … Read more
Researchers synthesize high-energy-density cubic gauche nitrogen at atmospheric pressure. Credit: Wang Xianlong A research group led by Prof. Wang Xianlong from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, has successfully synthesized high-energy-density materials cubic gauche nitrogen (cg-N) at atmospheric pressure by treating potassium azide (KN3) using the plasma-enhanced chemical vapor … Read more
About two million years after the formation of the Solar System, the first carbonaceous chondrites made of dust, chondrules, early condensates and iron-nickel grains agglomerated outside the orbit of the still young Jupiter. About two million years later, the CI chondrites were formed by photoevaporation. They incorporated a particularly large number of iron-nickel grains. Credit: … Read more
Intracellular H2 S accumulation regulates iron uptake activity via YgaV and is crucial for antibiotic resistance in E. coli. Credit: Tokyo Institute of Technology Antibiotic resistance and oxidative stress response are important biological mechanisms that help bacteria thrive, especially pathogenic bacteria like Escherichia coli. Hydrogen sulfide (H2S), a chemical messenger molecule, regulates several intracellular activities … Read more

Stepwise assembly of the 20S proteasome is mediated by multiple chaperone interactions. Credit: Nature Communications (2024). DOI: 10.1038/s41467-024-52513-0 Scientists at Sanford Burnham Prebys have developed a clearer picture of how crucial machinery in the human cell’s recycling process for obsolete and misshapen proteins—known as proteasomes—are formed. “Proteasomes are absolutely essential for health,” said Jianhua Zhao, … Read more
Credit: CC0 Public Domain Earth will capture a miniature, “second moon” this week, according to NASA scientists. The new moon is actually a tiny asteroid dubbed 2024 PT5. It will start orbiting the planet in a horseshoe path and stick around for a little less than two months before escaping Earth’s gravitational pull and going … Read more
The Amazon River in Leticia, Colombia. The Amazon River has seen its levels in Colombia reduced by as much as 90 percent, a government agency said Thursday, as South America faces a severe and widespread drought. The river—the world’s biggest by volume and which also flows through parts of Brazil, Peru, Bolivia, Ecuador, Venezuela, Guyana, … Read more
