Biologist at JAMSTEC exploring the evolution and frontiers of lifehttps://bsky.app/profile/masarunobu.bsky.socialhttps://bsky.app/profile/masarunobu.bsky.social/post/3myxowqan6c2lAn archaea strain from our closest relatives now in pure co-culture! Symbiosis, oxygen tolerance, and membrane protrusions found in Heimdallarchaeia of Promethearchaoeta (Asgard archaea) are our newest clues to the origin of complex life! @hiro-imachi.bsky.social https://www.nature.com/articles/s41586-026-11170-728 Oct 2026 21:27 +0000at://did:plc:xo7e3nqq3cgdulgsijvcsevp/app.bsky.feed.post/3myxowqan6c2lhttps://bsky.app/profile/masarunobu.bsky.social/post/3mwsor4b2w22gAmazing discovery led by Philip @radler92.bsky.social and Christa @archaea-vienna.bsky.social!!! Just being a (small) part of this massive effort was hugely inspiring. Can’t wait to see/explore more amazing biology of these archaea together!

Syntrophic microaerotolerant peptide-degrading anaerobic archaea w/ simple cell structure & protrusions. Features conserved across the phylum provide new insight into our ancestor’s biology! https://www.biorxiv.org/content/10.1101/2025.02.26.640444v127 Feb 2025 04:25 +0000at://did:plc:xo7e3nqq3cgdulgsijvcsevp/app.bsky.feed.post/3lj52euy3622khttps://bsky.app/profile/masarunobu.bsky.social/post/3lgvuypcrtc23Underground happy hour? Excited to share our discovery of a new symbiosis between subsurface bacteria and archaea bridged by syntrophic transfer of the smallest alcohol—methanol! @nature.com Work led by a former student Huang Yan, congratulations! rdcu.be/d7W2s https://rdcu.be/d7W2s29 Jan 2025 21:10 +0000at://did:plc:xo7e3nqq3cgdulgsijvcsevp/app.bsky.feed.post/3lgvuypcrtc23
