Beyond thrilled to share that our study has been published! This project encompasses years of work, including my thesis research on Asgard archaea in the @archaeal.bsky.social lab at @utmsi.bsky.social and @texasscience.bsky.social!!! #MicroSky #ArchaeaSky 1/12

Finally out in @nature.com: a new piece of the puzzle of how complex life evolved. Lead by @archaeal.bsky.social & @katyappler.bsky.social. Great collab with @greening.bsky.social and @kassipan.bsky.social. More pieces to follow soon! www.nature.com/articles/s41...

Fortunate my DECRA fellowship 'Uncovering divergent hydrogen-dependent methane metabolism in novel Archaea' was successful! Immensely grateful to @greening.bsky.social for the continued support and all present/past collaborators, mentors, and colleagues that made this possible!! tinyurl.com/45cc9ner

A widespread hydrogenase supports fermentative growth of gut bacteria in healthy people - Nature Microbiology

A previously uncharacterized microbial enzyme is responsible for the production of molecular hydrogen in the gut, which drives the growth of other bacteria and has implications for human health.

Cool study on aerotolerant methanogens! Options they might protect themselves from O2 include biofilm formation in response to O2 exposure and antioxidants (F420-H2-oxidases, rubredoxins, thioredoxins, and peroxiredoxins). This opens up a vareity of new possible habitats for methanogens.

Check this nice first first-author paper by Ning Hall—now out in Nature Geoscience! Our team had a blast supporting Ning on the isolation workflow, and a few of the standout Methanococcoides strains even trace back to our Danish waters. 🌊 www.nature.com/articles/s41...

New preprint up now! Interested in the evolution of halophily within DPANN archaea we decided to investigate the sister phylum to the Nanohaloarchaeota, GTDB phylum EX4484-52, for which we propose the name Caliditerrarchaeota www.biorxiv.org/content/10.1...

Caliditerrarchaeota, a new sister to Nanohaloarchaeota, provides insights into the evolution of DPANN halophily

The Nanohaloarchaeota are a clade of halophilic symbionts with small cells and genomes. Originally placed within the Euryarchaeota, they are now widely thought to belong to the DPANN archaea. However,...

Masterpiece paper from Ning, Perran, Amelia and co! Great mix of field-based geochemistry, laboratory manipulations, methanogen cultivation, and isolate / environmental genomics. An unexpected feedback between eutrophication and climate change that could shake up how we think about methane budgets.

1/3 Electricity from air! In the top journal Nano Energy today, we report the first fuel cell that makes power from air alone. We achieved this by using the enzyme Huc to oxidize ambient hydrogen. This results in a continuous low-level power from air and higher outputs with industrial waste gases.

Our new consensus statement on reducing and reporting contamination in microbiome studies is the cover image of this month's Nature Microbiology: www.nature.com/articles/s41... In the cover photo, you can see our postdoc Sophie Holland in fully PPE sampling the atmosphere of terrestrial Antarctica.

Guess who's the coverboi for @natmicrobiol.nature.com this month? 💁 A huge shout-out to Dr Rachael Lappan for entrusting me to carry out the sampling for this incredibly cool atmosphere microbiome project on her behalf, & to Braydon Moloney for capturing this moment in Antarctica last summer.

I'm absolutely taken by your work – and your team's work – on how microbes get by living from "thin air". it's only a "paradigm shift' for microbiologists brought up with the idea that bugs live by "feast or famine", what they do not only in the lab. but the famine part is way more interesting...

Energy from air? No problem! In our new preprint, we reconstitute the machinery that allows microbes to endure starvation. By using the trace amounts of hydrogen in air alone, they produce plenty of chemical energy (2 ATP) to get by. The only byproduct? Water. www.biorxiv.org/content/10.1...
