Our latest paper is out: rdcu.be/ev6Ym β€” one of my favorite projects. It began about 8 years ago when Nobel laureate Torsten Wiesel asked me: what transcription factors regulate new genes? I had no idea then. Now we have some answers.

It is heartening to see the success of brilliant young scientists who see, study, and share the beauty and wonder of the microbial world. Congratulations @couchmicroscopy.bsky.social! I look forward to learning new biology from the path you forge.

No, AlphaFold has not completely solved protein folding Biology is hard. Yes, even for AI.

AlphaFold is great, but contrary to public opinion it has not completely solved the protein folding problem. Much work remains to be done.

We usually use in situ imaging to obtain #plankton or particle abundance data, but sometimes we get a glimpse of how they interact with each other, like this huge group of Phaeodaria (Rhizaria) surrounding this crustacean (are they eating it?), 🌊

Somewhere in Atlantic - and sea is like glass for last few days. We are out here measuring carbon flux & how ocean removes all of that carbon. Microbes don’t work for us; so unless we understand the processes - we don’t know where tipping points are. Thankful to @NSF for supporting basic science.

BEHOLD! One of Earth's greatest lineages of life: the lil wiggle arm guys, Meteora.

These single-celled critters, originally found in deep-sea sediments, are SO DIFFERENT from other lifeforms on Earth that they're likely in their own kingdom (as in, the Animal Kingdom, the Plant Kingdom etc). πŸ§ͺ🌿

Slime molds eat the microbes on decaying plants but not the microbes on decaying animals. Badhamia (Physarum) polycephala is an unusually adventurous eater who also enjoys mushrooms, oats, and probably a number of other things!

This year's #ICOP2025 in Seoul was a big success! Many of us remember when the Seoul meeting was excitedly announced in Prague 2017, set for 2021. Wonderful to see it come through finally. The protistologists are my favorite community by far and it is amazing to see the field advance #protistsonsky
