I just learned a lab appropriate alternative to rock, paper, scissors- Kelp, Urchin, Rock. Kelp covers the rock, urchin eats the kelp, rock squashes the urchin!

The evolution of shape diversity through the lens of physics—explored in our new paper! A fruitful collaboration between our lab @EMBL, Salbreux’s lab @unige & others, led by @BailleulRichar1—now independent at @ENS_ULM—& Nicolas Cuny. bit.ly/3WRqdEa

Fantastic!

Happy #FluorescenceFriday! Today we're celebrating a crowd-favorite - Lamin B1!

Is it just me or does everyone’s lab look at them like they sprouted a third eye every time they invoke Maniatis in the lab? I swear that we isolated good nucleic acids in the 90s and we didn’t have Reddit.

Scientists unveil new wiring diagram tracing millions of connections in a bit of brain tissue Researchers say they have mapped more than 200,000 cells in a cubic millimeter of brain tissue and have traced how they're all connected.

“If you have a broken radio and you have the circuit diagram, you’ll be in a better position to fix it.” - Nuno da Costa

Thank you @b0yle.bsky.social for sharing our publication of the most complete map yet of the brain's wiring and activity in @geekwire.com!

Wow, so that still exists?! Awesome! I remember our lab having a good run because one of the members was a former member of the Yugoslavian national basketball team.

Distinct requirements for PI3K isoforms p110α and p110δ for PIP3 synthesis in mouse oocytes and early embryos

Developmental timing across species: From mechanisms to evolutionary insights Like choreography, development consists of a highly ordered suite of steps and transitions. Modifying developmental tempo can affect final size and composition of tissues, as well as their plasticity…

Nice work! Can’t wait to hear about this next week at DBSUMI.

This paper is now published at @diffjournal.bsky.social! Congratulations to all the hardworking students who made it happen! Shout out to authors 1 & 2! MJ is our “axolotl whisperer” and Raneesh is our computational wizard- both DVM/PhD students @ucdavisvetmed.bsky.social! 💫 doi.org/10.1016/j.di...

NOW HIRING - @adc-neuroenv.bsky.social is seeking a postdoc researcher to develop and optimize genetically encoded fluorescent and bioluminescent sensors tailored for marine model organisms.

Oops! Thank you for catching that…

Using wild animals for lab research has never seemed like a good idea to me.

And... it's live! In situ hybridization has been foundational for sea urchin developmental biology. Here we report a fully automated method to probe more than a hundred genes using a general purpose liquid handler.https://www.biorxiv.org/content/10.1101/2025.03.23.644641v1

The "superpower" of sea urchins is the fact that a single female can produce millions of embryos. In the next day or so we will share a new method to analyze gene expression methods in these embryos using a fully automated, open platform.
