Thrilled to see #choanoflagellates on the cover of Science Advances🤩. Our latest work "Electrical signaling and coordinated behavior in the closest relative of animals" out now. Link: www.science.org/doi/10.1126/... 👏 @jeffcolgren.bsky.social @msarscentre.bsky.social

Happy Ctenophore Day!
These glowing ocean drifters look like jellyfish but aren’t! They’re comb jellies, shimmering creatures that light up the sea with rows of beating cilia 💙🌈
Which species can you identify? 👀 Most are raised in @pawelburkhardt.bsky.social lab

Exciting news for #drosophila #connectomics and #neuroscience enthusiasts: the Drosophila male central nervous system connectome is now live for exploration. Find out more at the landing page hosted by our Janelia FlyEM collaborators www.janelia.org/project-team....
Male CNS Connectome
A team of researchers has unveiled the complete connectome of a male fruit fly central nervous system —a seamless map of all the neurons in the brain and nerve cord of a single male fruit fly and the ...

Amazing work by @thibautbrunet.bsky.social and his lab! I can’t stress enough how significant a development this is for Choanoflagellate research and it has been revolutionary for our work!

This is two stories in one: a case study/cautionary tale on developing genetic tools in new organisms, and the first hint at a gene regulatory network for choanoflagellate multicellular development (which turn out to involve a Hippo/YAP/ECM loop!) A 🧵

Happy Ctenophore day! Its a perfect day to celebrate such a small yet beautifully diverse phyla that comes in a wide array of shapes and colors. #Ctenophoreday

For CTENOPHORE DAY, a little survey:
Which end of this fishing Pleurobrachia is the mouth on? Please just "vote" in the comments — no definitive answers. 🦑🧪🌊

P.S. this is one of my earliest #ctenophore photos, shot on film in a home-built kreisel.

P.P.S. Legit data-gathering for a future paper.
A spherical comb jelly floating against a dark background, with its tentacles deployed, tentilla (side branches) fanned out. There is a number 1 above the body and number 2 below the body. Photo by S. Haddock taken around 1990.

HAPPY CTENOPHORE DAY (part II).

A full bucket of ctenophores for Ctenophore day - time to shimmer🌈🌊✨

Please watch till end: Mnemiopsis & Pleurobrachia included.

Alexandre @alexandrejan.bsky.social filmed and caught this ctenophore at the same time @msarscentre.bsky.social #ctenophores #GoPro

The fjords around Bergen are full with Mnemiopsis right now. Movie by the amazing @alexandrejan.bsky.social @msarscentre.bsky.social #ctenophores #GoPro

If you’re applying to your dream lab for an internship/PhD/postdoc, always send a second email 1-2 weeks after the first one if you don’t hear back.

I promise we will be grateful rather than annoyed. My email inbox is a disaster and I’m quite junior - and very few of us have secretarial support

Here it is! Postdoctoral position to identify the progenitors sensory organs in the regenerating legs of Parhyale

We've just been awarded a grant to study the cellular basis of regeneration – to track the progenitors of sensory organs in the context of leg regeneration, in our favourite crustacean tinyurl.com/parhyale, based on live imaging and cell tracking. The project involves some cool collaborations... 1/3

Nanotubes everywhere between neurons! A bit skeptical about these "dendrite-dendrite nanotubes" from a phalloidin staining in culture, but let's read on… www.science.org/doi/10.1126/...

Breaking News: Jane Goodall, one of the world’s most revered conservationists, died at 91. Her discoveries in the 1960s about how chimpanzees behaved in the wild broke new ground and represented what was called “one of the Western world’s great scientific achievements.” nyti.ms/42kpGxt

Comb jelly season has started in Bergen, Norway! 🌈🍂🧪
pawelburkhardt.bsky.social
Another season has started as well. We now find many different ctenophores in Byfjorden, a fjord that runs into the city center of Bergen.

Here the ctenophore Mnemiopsis leidyi: it uses a row of cilia called comb plates to swim. When hit by light, they create shimmering rainbows along their bodies.

Day 30 - Dream. The final day of #sciartseptember. My long-term dream has always been to create a series of illustrated guides that would help identify the various jellies and jellyfish of the would. Creating illustrations like the ones below to accurately ID species.

🌟 Thrilled to share that my lab’s first publication is now out in @natmetabolism.nature.com. Congrats to the team 🎉

🧠 We discovered that neurons use endogenous fatty acids as an energy fuel, challenging long-standing models of sugars being the exclusive energy source for neurons. 1/3
