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!!!

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!!

📢 Extra, extra: our collaborative study on trace gas oxidizers in a warmer soil is out as a preprint

In our latest collection of free education resources, we explore bioconversion with Professor Esteban Marcellin, Professor @greening.bsky.social and Dr Leonie Van 't Hag from the RECARB hub. They are using bioconversion to convert greenhouse gases into proteins.

Why can our farts ignite? Time to find out (and quite a bit more) in our new paper in Nature Microbiology led by the amazing Dr Cait Welsh. Integrating atomic-to-ecosystem level insights. www.nature.com/articles/s41...
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.
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

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.
3/3 Very grateful to collaborate with chemical engineers Dr Kaiqiang He and Distinguished Professor Huanting Wang to make this dream a reality. Check out the paper here: www.sciencedirect.com/science/arti...
2/3 Huc has several exceptional properties for a hydrogen catalyst. It has a high affinity for hydrogen, is insensitive to oxygen and carbon monoxide poisoning, and is also thermally stable. This enables it to use feedstocks like air and waste gases no chemical fuel cell can.
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.
Does the atmosphere harbour a resident, growing microbial ecosystem? ⛅
Here in @jgrbiogeo.bsky.social we outline how theoretical tools 📝 & modelling 💻 can bring us closer to the answer

Our article showing energy production from air alone is in PNAS today. This paper provides an ultimate biochemical proof that microbes can survive simply by 'making' energy from air (making two ATP per molecule atmospheric H2 consumed) and has biotech applications. www.pnas.org/doi/10.1073/...

Thank you!!!
Thanks so much!!!
Extraordinary keynote lecture by Prof. Chris Greening @greening.bsky.social about Microbial oxidation of atmospheric trace gases: from enzymes to ecosystems.
#FEMS2025 @femsmicro.org
Getting inspired @femsmicro.org ! Thanks @greening.bsky.social for the very interesting talk !
Haha! Saw you briefly yesterday but so sorry I missed your presentation!
Day 3 at #fems2025 started with an exciting and inspiring keynote by Chris @greening.bsky.social on microbes living out of thin air

A must read. Our lab learned the hard way just how problematic contamination can be! We hope this article will be a wake-up call for many. Many thanks to chief editor Dr Emily White (@emily-white.bsky.social) and co-lead Prof Noah Fierer (@noahfierer.bsky.social) for driving this article.
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.
A screenshot of the Nature Microbiology website showing the journal cover - me in a cleansuit, gloves, and dark snow goggles attaching a filter to an air sampling unit. Text reads: Guidelines for low-biomass microbiomes. Pictured here, Sophie Holland attaches a filter to an air sampler to study the atmospheric microbiome of Somoveken Glacier in Dronning Maud Land, Antarctica. The pristine environment and incredibly low atmospheric biomass require multiple precautions to avoid sample contamination, including wearing full personal protective equipment over warm weather gear. In this issue, Fierer, Greening and colleagues working on host-associated and environmental microbiomes present guidelines and best practices for studying low-biomass microbiomes in a Consensus Statement.

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. [1/2]
Our paper demonstrating that within-species warfare interactions are ecologically important on human skin is now published in Nature Micro! www.nature.com/articles/s41...
Hope this is useful - consensus statement "Guidelines for preventing and reporting contamination in low-biomass microbiome studies" rdcu.be/er3Io
An editorial in @natmicrobiol.nature.com highlighted issues with reports dealing with low-biomass microbiome.
A new consensus statement provides guidelines to prevent and report contamination in low-biomass studies.
A step towards ensuring rigour!
