A Sharon Begley byline, almost 5 years after her death. Upon hearing the news James Watson had died, a STAT reporter said in our Slack, "I wish I could read what Sharon would have written." Incredible news: Sharon in fact did pre-write a Watson obit. And it is masterful and excoriating. 🧪🧬🧫

James Watson, dead at 97, was a scientific legend and a pariah among his peers
James Watson, the co-discoverer of the structure of DNA who died Thursday at 97, was a scientific legend and a pariah among his peers.

Some interesting work on vitamin B1 production in marine OMZ led by Kristin Bergauer at @geomarkiel.bsky.social just came out! I got to contribute some bioinformatics analysis to round it out. I think the final result is quite an interesting paper: academic.oup.com/ismecommun/a...

Dark ocean archaeal and bacterial chemoautotrophs drive vitamin B1 production in oxygen minimum zones
Abstract. Vitamin B1 (thiamine) is essential for all cells, yet many marine microbes cannot synthesize B1 de novo. Dissolved thiamine and its related chemi

Happy to see a large chunk of my PhD work published today in Cell Host&Microbe: www.cell.com/cell-host-mi... We conducted fluorescence-activated single-cell sorting of active predatory protists in the ocean and recovered symbionts with cool evolutionary positions close to animal pathogens.

the third chapter of my PhD is now published! 🚨 We describe the protist symbiont diversity of the termite species Reticulitermes tibialis. This project was performed in a course-based undergraduate research experience (CURE) which was super fun 😊 #protistsonsky authors.elsevier.com/a/1kaMa56A9x...

@stevestuwill.bsky.social you posted on 𝕏 on Dec 5, 2020 this stunning video - why not repeat on 🔵bsky ? (sorry, I did)... "Time-lapse footage of a vampire amoeba: a microscopic organism that feeds on algal cells by breaking through their cell walls and sucking out their insides." #ProtistsOnSky

I am looking for an ERC-funded postdoc to work on spatial proteomics of microalgae (red algae and glaucophytes). The ideal candidate will have experience with mass spec and data analysis (R), but above all a keen interest in broad eukaryote evolution and protists #protistsonsky (1/2)
