Excited to share our latest work using AI-designed proteins to block heme-piracy by E. coli. Published in @natcomms.nature.com. A team effort between my lab and the ‪‪@knottrna.bsky.social‬ ‬lab, with experimental work led by the talented @danielrfox.bsky.social www.nature.com/articles/s41...

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.

New #methanogen culture just dropped! Check out the 'Methanonezhaarchaeia'! Happy to see this one out. A new methylotrophic methanogen cultivated from a hot spring in Yellowstone National Park. Gives insights into the metabolic diversity and evolution of this group. #microsky 🦠🔥 tinyurl.com/yw8ku2bj

In an unprecedented move, the US National Institutes of Health has begun mass terminations of research grants that fund active scientific projects because they no longer meet “agency priorities”. https://go.nature.com/4bpG2It

Just got an email from the Fulbright Association. As of right now, funding has been cut off to 12,500 US citizens currently abroad and and more than 7,400 foreigner scholars and students in the United States

Isolated in just 3 years! (previously, 12 years). We obtained two strains from 'Hodarchaeales', proposed to be closest to our archaeal ancestor. Our analysis suggests the ancestor was an anaerobic, syntrophic, peptidotrophic, archaeon with a simple intracellular structure and possible aerotolerance.

Would you expect that Bacteria use an archaellum for swimming? We didn't, but we found that some Chloroflexota do! Find the story here: www.biorxiv.org/content/10.1... A little thread below 1/n

To update people on the NSF PRFB situation: despite the court challenge and rescinding the original memo, the NSF has continued to comply with the executive order. They have not communicated with us at all and our paychecks are still canceled indefinitely. I know people who cannot pay their rent.

In Nature Chemical Biology today, we reveal how microbes clean our atmospheres by consuming carbon monoxide (CO) gas. A methodological tour de force from Ashleigh Kropp, Rhys Grinter, and David Gillett with broad implications for the atmosphere and bioenergetics. www.nature.com/articles/s41...

American science and medicine has been thrown into chaos and uncertainty over the past week. Here are some stories to get up to speed. 1/12

I am very honored that our paper was selected by PLOS Biology as one of the editors top pics for 2024!

New paper out on which I am a co author on studies of metagenomes from Tramway Ridge in Antarctica phylogenomics.me/2024/12/19/n...

I apologise for HydDB being down. Aarhus University decided to stop hosting it at quite short notice. However, we plan to relaunch first thing next year and are in the midst of creating a much-needed HydDB 2.0. HydDB 1.0 is good for hydrogenase information, but our HMMs best for classification. 1/2

Our study on drug-gut microbiome interactions is out! 🦠💊 We show that the #Parkinson's drug entacapone induces iron deficiency in microbes, leading to selective inhibition of microbial activity. @cemess.bsky.social @sotonbiosciences.bsky.social #BostonUni Check the full story here: rdcu.be/d0ZAQ
