New Paper 👇 Evolutionary trajectory of microbial sulfur oxidation pathways recapitulates Earth’s oxygenation history #microsky 🧫🦠 #microbiomesky www.nature.com/articles/s41...

James Maxwell, one of the scientists who helped create the discipline of organic geochemistry, recently passed away. He was an inspiration before I came to the @ogu-bristol.bsky.social @bristoluni.bsky.social; and afterwards, he was a friend and mentor.

@weareagc.bsky.social's Volume 2 issue 1 is complete! Read all 10 articles for free here: journals.uu.se/AGC/issue/vi... Thanks Jeanne Caumartin, Karim Benzerara and Christophe Tomazo for providing the cover photo!

Did you catch the JOIDES Resolution in last week’s XKCD comic? Check it out! https://xkcd.com/3266/ In addition to IODP Expeditions 307 and 329, try to find DSDP’s Hole 504B, drilled by the Glomar Challenger, and the originating Project Mohole.
