Researchers Have Uncovered a Missing Piece in Life’s Origin Story Deep beneath the ocean’s surface, mineral-rich hydrothermal vents may have hosted a critical chemical reaction that helped spark life on Earth.

Researchers at the University of Alberta report that they may have identified a missing piece in one of science’s biggest questions: how life first began on Earth. scitechdaily.com/researchers-... #astrobiology #geochemistry #AbSci #science #SciChat

New insights on ​the Cambrian ROECE event🦀

​By combining new CAS sulfur isotope data with COPSE modeling, we’ve identified a link between anoxic water shoaling and the C-S isotope excursions during this trilobite turnover.

A Double-Edged Sword: The Global Oxychlorine Cycle on Mars - Eos Global detections of oxychlorine salts reveal a complex, 4-billion-year chemical cycle on Mars. They can act as de-icing agents, oxidants, a hazard and a vital resource for future human exploration.

A new #AGUPubs study investigates the state of the knowledge and discusses potential areas of future exploration of oxychlorine species, an important component of the Martian surface.🚀
