Keynote - Slow, energy-efficient, and mysterious life deep...
summary
Deep marine sediments contain huge, surprising biomass — roughly a third of the planet’s microbes, “about 10,000 times the number of stars,” yet most never grow in the lab. Claims: extremes of very slow growth (months to decades to 50+ years) and cells persisting potentially hundreds of thousands of years. Methods: Joides Resolution coring, droplet flow cytometry and single-cell genomics with whole‑genome amplification, metabolomics that finds ~20 compounds including allantoin metabolism, and culturing that shows zero overlap with cultures.
