‼️I'm looking for a postdoc‼️ Come join effort in using metagenomes to quantify microbial catabolic potential and carbon substrate availability at the ecosystem level. We seek to understand evolutionary forces shaping the carbon cycle. Part of ccomp-stc.org careers.peopleclick.com/careerscp/cl...

New preprint is out where we report a new obligate (?) methylotrophic bacteria with diel cycle of methanol dehydrogenase transcription in surface seawater, with implications for marine lanthanide and carbon cycling. Where the methanol comes from is a mystery! www.biorxiv.org/content/10.1...

Our latest, led by @jameswclark.bsky.social of @milnerevolution.bsky.social shows that the notorious mismatch between molecular and palaeontological estimates for the timing of origin of angiosperms is a consequence of equivocal interpretation of their fossil record @bristolpalaeo.bsky.social

@seandstacey.bsky.social #AddMicrobiology Thank you!

Fascinating! I have always wondered about how to think about the impact of gradual vs punctuated evolutionary dynamics on (my interest is particularly microbial) phylogenetic clock models. This paper seems to offer a general framework for doing so
