"The total amount of intracellular phosphate stored in the benthic foraminifer Ammonia confertitesta in the Wadden Sea during a bloom is as high as around 5% of the annual consumption of phosphorus (P) fertilizer in Germany."

Very excited to see this! "Thus, we can deduce that [the first eukaryote common ancestor] was an anaerobic, syntrophic, peptide-degrading, mesophilic archaeon that had simple cell structure with branching protrusions and no endomembrane system."

#OverheardAtCarnegie: “Those who look through microscopes too rarely talk to people who look through telescopes.”

Adding planktonic algae to anoxic marine sediments promotes the anaerobic growth of phagotrophic #eukaryotes. The #Neoproterozoic Rise of Algae may have similarly promoted benthic phagotrophs, directing carbon, energy, and nutrients to early animals. #ProtistsOnSky www.science.org/doi/10.1126/...

Our latest: a Richard Boyle (Exeter) production, using simulations to show how differential selection of biogeochemical cycles can lead to planetary homeostasis, with some empirical data from @emoody.bsky.social and @sabifo4.bsky.social @bristolpalaeo.bsky.social

Had fun writing this with @jmacalad.bsky.social and @astrowright.bsky.social!

The "hard-steps" model argues that human-like life was unlikely to evolve on Earth and is vanishingly rare in the Universe. Here, in our new Science Advances article, we challenge its foundational logic: www.science.org/doi/10.1126/...
