    Dear esteemed TWIM hosts, many thanks for another interesting episode. I would also appreciate your thoughts on recent references to bacteria surviving for millions of years in deep ocean cores (See Morono, Y., Ito, M., Hoshino, T. et al. “Aerobic microbial life persists in oxic marine sediment as old as 101.5 million years”. Nat Commun 11, 3626 (2020)). I have been trying to understand the implications – such as pathogenic bacteria potentially surviving longer than anticipated (global warming leading to ice melting has been proposed to lead to a release of historic pathogenic bacteria and viruses…) – and also any chance of this being due to contamination? Many thanks, Rich
