This slim book is a mix of science, history & natural history, beautifully written, as to be expected from the author of "The Shipping News," one of my favorites. simonandschuster.com/books/Fen-Bog-…

I discovered Marcia Bjornerud from a great review of this book in the New Yorker (8/26/24) . Wish she were teaching when I was at Lawrence where she's on the faculty. Lawrence University us.macmillan.com/books/97812508…

Rather than Bjornerud's latest, I picked up an earlier book, Timefulness. Although a geologist she says the biosphere is a "microcracy" & microbes will take over when "larger, arriviste lifeforms falter." Of course they already rule. press.princeton.edu/books/hardcove…

Even if you don't want to read the entire review (but you should), at least check out the list of related books at the end. The Story of Earth's Climate in 25 Discoveries: How Scientists Found the Connections Between Climate and Life inquisitivebiologist.com/2024/11/08/boo… via @inqbiol

Submit your abstract for the ASM Microbe annual meeting in Los Angeles I'm organizing a symposium on Microbial Dormancy and I hope to see your abstract and discuss with you there. Early abstracts close Dec 3, don't delay! abstractsonline.com/pp8/#!/20974/s…

I am proud to have represented EcoMicroLyon and our research #MicroRescue and THE MICROBES at the recent colloquium by the Fondation Pierre Verots My talk (in English!) is an accessible overview as to why microbes are important for climate change youtube.com/watch?v=QDmSTV…
