Molecular pendulum shuttles protons to enable rapid hydrogen production in enzymes

Nearly all metabolic processes require protons—positively charged hydrogen atoms. Although these are abundant in the cellular fluid, the biocatalysts involved depend on mechanisms for efficiently capturing protons and transporting them to the site where catalysis occurs. Enzymes
Nearly all metabolic processes require protons—positively charged hydrogen atoms. Although these are abundant in the cellular fluid, the biocatalysts involved depend on mechanisms for efficiently capturing protons and transporting them to the site where catalysis occurs. Enzymes from microorganisms can produce hydrogen (H₂) by combining electrons with protons.
These so-called hydrogenases are so efficient that one biocatalyst can capture nearly 10,000 protons per second.

Earth's core may have been leaking hydrogen for billions of years
When Earth formed billions of years ago, its metallic core was wrapped in a global ocean of molten rock, which eventually cooled and crystallized to form the mantle. Today, when deep-rooted mantle plumes rise toward the surface and produce volcanic eruptions, the resulting lava c

Fully implementing methane plans could reverse emissions growth but miss 2030 target
A new study, led by IIASA researchers and coauthored by UNEP colleagues, finds that if governments fully implement their methane reduction plans, they could reduce global emissions by 11% between 2020 and 2030. This would reverse the current trend of increasing methane emissions,
