Sabemos que diminutas formas de vida, como las bacterias, flotan en nuestra atmósfera. Pero ¿también proliferan y forman comunidades en ella? Una nueva investigación sugiere un enfoque de modelado que podría ayudar a responder esta pregunta. eos.org/research-spo...

Many years ago I wrote an unfunded😕 grant proposal to explore novel biogeochemical feedback loops in permafrost & marine cycles. www.theguardian.com/world/2025/a... Today, this remarkable reporting about a new type of microbial feedback loop operative in Svalbard, accelerating glacier decay. 🧪

We know tiny life-forms like bacteria float through our atmosphere. But do they also proliferate and form communities there? New research suggests a modeling approach that could help answer this question. eos.org/research-spo...

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 Congrats lead author @drmartinezrabert.bsky.social @mioceanologie.bsky.social 🧵 thread 👇 tinyurl.com/7pdfm7uw

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/...

How may theoretical ecology & evolutionary theory push microbiology forward? At Environmental Microbiology, I am commissioning a series of Perspectives exploring that question. Excited to share them in the 🧵 below The series is open, so do get in touch if you'd like to propose a new contribution!

Ammonia released from penguin guano may help to reduce the effects of climate change in the Antarctic by contributing to increased cloud formation, according to an analysis in Communications Earth & Environment. go.nature.com/4k8rAYU 🧪

Congrats to @drmartinezrabert.bsky.social @reymourot.bsky.social & Sibylle Lebert @mioceanologie.bsky.social for representing @erc.europa.eu #ERC_SIESTA & @hfspo.bsky.social Atmosphere projects at JSM3 conference in Marseille ☀️ while I’m in Antarctica 🌚 #SD049 @cnrs.fr @cnrs-insu.bsky.social

Come and join me in Marseille ☀️🌊🐟🔬🇫🇷🇪🇺

We currently have days of persistent positive degrees in the depths of winter in the high Arctic (79°N). Shocking temperature anomalies are becoming the norm. Already exceptionally high rainfall this winter, and thick ice covers the tundra instead of the usual snow. Unprecedented and terrifying 🌡️

Are they [atmospheric microorganisms] also awake contemplating this marvellous sunset?

New paper online! 'Competitive and substrate limited environments drive metabolic heterogeneity for comammox Nitrospira.' In this study we aim to connect the early discoveries of comammox Nitrospira (one in aerobic conditions and the other <3.1uM O₂) using Individual-based Model. rdcu.be/dkEa6

"Nothing is less real than realism. Details are confusing. It is only by selection, by elimination, by emphasis, that we get at the real meaning of things" - Georgia O'Keeffe. Art and science in a single quote. I love it.

Decided to post this here. It seems good that my first post is also the first preprint with an author from my lab! We used previously identified metabolic rules to predict microbial community assembly along a temperature gradient (1/12). www.biorxiv.org/content/10.1...

Hiya!! Here a theoretical ecologist and bike rider (for now on the road, but soon also in the mountains). In my first year of postdoc at University of Wisconsin-Madison. Nice to meet you!
