Got to know George briefly since I came west, and what a magnificent, gentle, genuine and humble soul he was. I'll never forget geeking out in the mineral gallery one evening, and thinking how his excited curiosity was sincerely youthful and infectious.

WOW!
An incredible discovery. The first ever image of a baby exoplanet embedded in the dust rings from which planets are forming around a star. Confirms the developing view of planet formation that weβve never before seen in action.

Just gave this a spin on a paper I've been working on for too long and WOW. Even though it was outside its topic domains, the feedback it highlighted was oh so constructive and insightful. Highly recommended and congrats @odedrechavi.bsky.social and team on an awesome tool!

I still contend that >90% of the benefit of writing a review isn't the audience. It's for the author going through the literature, finding gaps in knowledge, learning how experiments are done, etc. It really isn't about writing a review. It's about doing the review yourself. AI can't do that for you

As night falls on Pasadena today after goodbyes to many colleagues and friends, it's important to remember that while places and their history are important, ideas and inspiration live within people. As a community we shouldn't forget holding strong those ties that nurture optimism and innovation

GenomeFISH: genome-based fluorescence in situ hybridisation for strain-level visualisation of microbial communities
Abstract. Fluorescence in situ hybridisation (FISH) is a powerful tool for visualising the spatial organisation of microbial communities. However, traditio
Very excited to share the first paper out of my Postdoc @CMR:
GenomeFISH: genome-based fluorescence in situ hybridisation for strain-level visualisation of microbial communities.

Functional biogeography of marine microbial heterotrophs
Heterotrophic bacteria and archaea (βheteroprokaryotesβ) drive global carbon cycling, but how to quantitatively organize their functional complexity remains unclear. We generated a global-scale unders...
Out in Science! Zakem et al. mechanistically modeled global marine prokaryotic functional diversity, grounded with field data. Shifts in community composition drive respiration and thus biological C storage. This facilitates C cycle projections in a warming ocean

Diving robot enables complex measurements and analyses
Exciting! We have successfully deployed our in situ mass spectrometer, developed together with @marumunibremen.bsky.social, on their brand new #ROV #MARUM-QUEST 5000. It provides real-time inΒformΒaΒtion on gas conΒcenΒtraΒtions in waΒter 400Β°C hot and 4000m deep.

New paper out!
We discovered a tiny archaeon with the smallest known archaeal genome β only 238 kbp!
Candidatus Sukunaarchaeum mirabile has almost no recognizable metabolic pathways and may rely heavily on a host to survive.
It also represents a novel, deep-branching lineage in the archaeal tree.

The crown of a crinoid sits just within smooth grey rock, its arms gently folded over one another as it lays on its side. A partial stalk extends from the bottom of the crinoid's crown (the calyx), appearing as if it's just been separated from the rest of its body.
A cropped image with a closer view of the crinoid's long, tendril-like arms and rounded calyx. Small, feather-like extensions (pinnules) hang from the arms and gently drape over one another.
Happy #FossilFriday, check out this beautifully preserved crinoid! These animals have inhabited the oceans for 480 million years, and they're relatives of sea urchins and sea stars. This specimen is long fossilized, but looks like it just died and fell into the seabed's embrace. (1/3)

π§ͺπ¦ π Nitrogenases are one of the most ecologically important enzymes on Earth. They're ancient too.
In this PREPRINT, Cuevas-ZuvirΓa & Co. analyze how their structures tell the story of planetary-wide ecological changes

Now that we've had a migration of twitter people here, I figured it's a good time to re-share our most recent work, measuring the growth rates of individual microbial cells with Raman. Super cool technique if you're curious about quantifying microbial activity in/on minerals, plants, etc!
