We are all ears kenneth ! and happy to help.

We had already tried some Chem fixed samples with Kenneth, a couple years back without much success. I think going cryo would be needed here ! And yes, happy to try again

Thank you @mollyherring.bsky.social for the stunning showcase 😍

Like what you see? Come ExM with us! Let’s flood the internet with microbial marvels 🦠

Thx for @mollyherring.bsky.social for featuring our recent work with @centriolelab.bsky.social and our quest with @gautamdey.bsky.social & the support of the @moorefound.bsky.social to look for the beauty in every #eukaryote out there using #Expansion #Microscopy #UExM

Priority effects inhibit the repeated evolution of phototrophy - npj Complexity npj Complexity - Priority effects inhibit the repeated evolution of phototrophy

New paper out! Here's a puzzle: phototrophy, the ability to use light for energy, is one of life's great innovations. It evolved early and transformed the biosphere. But it evolved 2x. Why not just once, why not more? Our work suggests the answer is priority effects.

Today is the last day of the Rigi Workshop 2026 organised by @dudinlab.bsky.social @michaelraissig.bsky.social and @scnat.ch.Thanks to the participants and the fantastic speakers: Gautam Dey, Edwige Moyroud, Annika Guse, Susana Coelho, Lauren Saunders and Jan deVries. #SwissSocietyofPlantBiology

Although weather was better yesterday, we are still having a blast today... and the discussions with this view are just top notch

Cant wait to read it guys !.
Enjoy the writing and company ;).

I like the jackson pollock vibe indeed.

This is Termite guts !!! PARABASILIDS

Not le tyle de la maison du tout :D
No animal cell lines in my culture room EVER :D

@fmikus.bsky.social just showed me this #UExM image ...
I mean ! What do you think its is 😍😍

It was a really fun couple of weeks in the lab !
I also very much enjoyed being in full handle of the #Zeiss 3Dsim scope provided generously for us to explore the various samples.

An axostyle :) a big fan of the axostyle

Maaaan.

You should try the PSII antibody and Rubisco !

Keep them flowing !!

Amazing Roberto ! What a way to come back !

In remembrance of Peer Bork  | EMBL EMBL and its community are deeply saddened by the death of Peer Bork, the organisation’s Interim Director General.

This one was quite the journey! The paper describing the #ChlamyDataset is finally out and on the cover of Mol Cell!

This beautiful rendering made by co-author @jessheebner.bsky.social and Holly Peterson shows an instance of mitochondrial fission found in the dataset 😍

[Maybe long thread ahead]

• evolution of cellular life & major transitions
• molecular paleobiology
• experimental evolution
• systems approaches to early life

Whether your work spans chemistry, biology, evolution, earth sciences, or interfaces between disciplines, we’d love to hear from you.

Come join us !

While the call may sound focused on prebiotic chemistry, the scope is much broader; we’re looking for candidates at any professor level working on questions around the origins and early evolution of life, including (but not limited to):

If you know of any exceptional PhD student, who is ready to become independent - you should defnietly consider this EPFL opportunity !!

This is the cover proposal I made for our recent paper!

It’s Pyramimonas diskoicola — a very beautiful green flagellate and one of those cells that makes you stop and stare for a while.

I tried to capture its shape, symmetry, and general vibe :)

I can't promise that one yet...fingers crossed we have you with us Monday

We can't see the mountains today, but the trains are still on time...

The images shows an array of 6 Expansion microscopy images of cell nuclei (three columns and 2 rows). each image was taken with a different SPY-DNA probe to stain the nuclear DNA and is pseudocolored to the fluorescence wavelength of the SPY-DNA probe. Trom top left to bottom right: SPY505-DNA (green); SPY555-DNA (magenta); SPY595-DNA (yellow); SPY620-DNA (orange); SPY650-DNA (red); SPY700-DNA (darker red). a white scale bar of 50 micrometers is given for each image to get an impression of the scale of each nuclei.

Are you staining DNA in your ExM samples?

We have awesome news for you! All our 6 SPY-DNA probes work beautifully well with the U-ExM protocol.

You can now tune the color of the DNA channel to your needs, according to the fluorophores on your preferred antibodies.

Whatever leftover gels (those you don't stain), can be kept at 4°C in PBS + Azide 0.01% + BSA 2% for months.
You could even put them in multiple 50% glycerol washed and leave them at -20°C.
Even stained gels, if left in PBS+Azide could keep their signal for weeks.
One of the big pluses of ExM

wow - if you have enough cells on the gels, and wanna send us a spare gel piece, we can defnietly try some more antibodiess !

Big Congrats to Pierre & the Gönczy team.

5y already...
It does somehow feel a blink of an eye. Not sure if this is a good or a bad sign. But hopefully to more eye blinking mate.
