Time lapse of an odd little monster. Presumably some kind of cercozoan from brackish water. #protistsonsky

Here is a myxomycete plasmodium that I isolated off a wet leaf onto the bottom of a vented flask. Realtime phase microscopy.

Yeah, they are delicious 🤤

no 'swimming' by 𝘝𝘢𝘮𝘱𝘺𝘳𝘦𝘭𝘭𝘢, definitively no 'staying still'. just a relaxed walk towards the lunch...

It's like me at Christmas Eve dinner eating pierogi 🥟 😅

Wow 😲 . That's impressive work!

Be aware of Tyrannomonas regina while having a swim this summer 🦖🦠🙀. Congratulations to @smallthingslab.bsky.social

Excited to be at #SMBE2026 in Copenhagen! Don’t miss Symposium #17: “Unicellular organisms in major evolutionary transitions.” Registration is now open!

I've been gone for awhile because bluesky was (is) banned in Mississippi :)

Now that I have a VPN, here is a timelapse of diatoms from @hhmijanelia.bsky.social pond!

So beautiful 😍

Is it a flagellate? A tiny ball with tentacles? Contamination in my ciliate culture? NEW SUPERGROUP OF EUKARYOTES? Yes to all 4! Meet Solarion - just out in #Nature doi.org/10.1038/s415... Huge congrats to Marek Valt, Cepicka Lab & the star team! Very happy to be part of this project. #ProtistsOnSky

This is a beautiful thread on mechanisms of a property of [some? only giant?] unicellular #protistsonsky that I wouldn't even believe is possible if it wasn't demonstrated so clearly: the ability of a single cell to heal cuts! 🤯🤯🤯

Fung-wong: Super typhoon hits Philippines as nearly a million evacuate Typhoon Fung-wong, with sustained winds of 185 km/h (115mph), made landfall on Sunday evening local time.

Typhoon #Fungwong has made landfall in the #Philippines, where more than 900,000 people have been evacuated and two people have died.

The #storm was upgraded to a #SuperTyphoon before landfall, with sustained winds of around 185 km/h and gusts of 230km/h

For decades, Palestinians have resisted occupation, violence, and oppression.

Now, those who tried to bring them aid say they faced the same brutality.

Ecological processes shaping marine microbial assemblages diverge between equatorial and temperate time-series Marine microbial communities are structured by a complex interplay of deterministic and stochastic processes, yet how these vary across latitudes remains poorly understood. Most long-term microbial ob...

Chapter 3 of my thesis is now available as a preprint in @biorxiv-ecology.bsky.social

We compared 3+ years of coastal microbial time-series from an equatorial site (EAMO, 6°S) and a temperate site (BBMO, 41°N).

Our work reinforces the need for observatories across latitudes to track ocean change.

It's heartbreaking it's over 😭 We're lucky we have #SAME19 to look forward to ❤️❤️❤️

Group pic SAME18!

@same18-bcn.bsky.social finally has started with a plenary by Stefan Bertilsson #SAME18

SAME18 is taking off!

Some scientific stories, like the one we just heard from @johncork.bsky.social at the #mbkceesme2025 on human harnessed and highly exploited #yeasts, could easily inspire a movie or a TV series!!!

Yes, there’s more to worry about how we do our science with microbes
