Thread 15: Neural Crest (focusing specifically on neural)

Again, I learned this information and compiled it from my notes on the Neural unit in my biology advisor's 2024 dev bio class.

This thread will largely focus on Path 1 Neural Crest Cells. (1/n)

Please check out our new preprint! Using single cell analysis paired with HCR to visualize transcript localization we have identified cell and tissue-specific expression of various genes encoding tubulins, kifs, and dyneins during neural crest development!

Stages of embryo development

How to draw an owl: Draw some circles. Draw the rest of the fucking owl.

It's slightly upsetting that many online diagrams of a blastocyst turning into an embryo are very 'how to draw an owl'

Sometimes, the only way to build back up is to let everything fall apart. This is certainly true at the cellular level. www.quantamagazine.org/break-it-to-...

Thank you @ehannezo.bsky.social for a great day of Science and friends at @istaresearch.bsky.social. Good to see the the fruitful interface of Physics and #DevBio at work,

Excited to have started my new lab in Human Genetics at Pitt Public Health!

We study wound healing in diabetes & aging using adult zebrafish. Check out this movie showing neutrophil dynamics after injury.

Now recruiting research staff, grad students, and postdocs. DM me if interested.

Let's get this hashtag started! The 2026 Santa Cruz Developmental Biology Meeting is happen this August! We will share updates using #SCDB26.

Can't wait!

Recent studies in living animals reveal that the cytoplasm is a thick, jam-like fluid. And yet, miraculously, hoards of molecules find their way to each other in every crowded cell. www.quantamagazine.org/the-biophysi...

We‘re looking for a motivated Master student to join our team!

The genome isn't a blueprint. But what is it?

I originally imagined this as a reported feature on metaphors of the genome, but it ended up being an essay.

And at the end I share the metaphor I personally ended up landing on. If you want to tell me why it is wrong, you'll need to read the story ;)🧪

Annnd we did Secret Santa gift exchange in February (again)😁! It seems like February Secret Santa has become our lab tradition now. Gastrulating into the holiday spirit in February ;).

New preprint! We show how mesoscopic nonequilibrium fluctuations in active gels emerge from the breaking of detailed balance at the molecular scale. Warning: Long technical paper ahead! Enjoy! @mpipks.bsky.social @ub.edu @ubics.bsky.social @icreacommunity.bsky.social

🔬 New paper in Developmental Biology 🐟
Our researchers have now tested a largely ignored hypothesis—that the geometry of an embryo drives its development. Read more in the 🧵below.

🚨 What if evolution is the ”law”… and networks are the machines that do the work?

In this paper (just published) I try to formalize how living systems are non-equilibrium, information-processing, adaptive matter. With a great biological flavor! 🧪🌐🌍🧬🦠

Unbelievable news.

Pancreatic is one of the deadliest cancers.

New paper shows personalized mRNA vaccines can induce durable T cells that attack pancreatic cancer, with 75% of patients cancer free at three years—far, far better than standard of care.
