@a-weberling.bsky.social & I characterize oogenesis from initiation in the germinal bed to ovulatory follicles for the first time in the brown anole, a powerful reptile model for evo-devo & functional genetics!

i was told a US donor site to support FlyBase will be live shortly, which we should all broadcast to everyone we can. however, there is a delay (red tape) to be able to provide invoices to bill grants, but its in process. 🪰

@a-weberling.bsky.social , @shylonatasha.bsky.social et al. continue to provided stunning images and insight into early reptilian development with this new paper on chameleon embryogenesis 🦎🥚. Check it out!
1/6
Preprint Alert
Ever thought that humans & chameleons look alike?
We follow chameleon development from fertilisation to oviposition & uncover the process through which they form an epiblast lumen that exhibits striking similarity to human embryos

Very cool work on embryo-yolk signaling in zebrafish!!
The preprint of my dear friend Svetlana Jovanic showing that
"cell behaviour during gastrulation is robust to the deficiency of yolk topology & signalling originating from the yolk syncytial layer."
is now online!
Super interesting read! #zebrafish #embroids #DevBio

Yet another heartbreaking and short sighted decision. The folks at NSF are so supportive of the scientific community. Their funding is what has allowed my lab to grow and succeed. These cuts are so destructive.
NEW: NSF confirmed that they fired 168 employees today, out of their staff of ~1,500 feds.

This includes some people who'd finished their 1-year probationary periods, which were extended to 2-years last month without explanation. More to come.

This is a fantastic program! You can apply as a mentor to work with a student who will travel to your lab, or you can apply as a mentor to work with one of your current students. I highly recommend it! I have done both and it’s been so rewarding. ❤️
We are extending the #ChooseDevelopment application deadline to Wednesday, February 5, 11:59 PM ET. Undergrads from underrepresented racial or ethnic groups, first-generation college students, veterans & students with a disability are eligible. bit.ly/3FwHqYp #devbio

NSF froze payments to researchers.

State AGs said it was unconstitutional for exec branch to pause congressionally mandated funds.

Judge issued restraining order.

Payments resumed.

But some inconsistencies in what the NSF has said (thread):
www.statnews.com/2025/02/02/n...
National Science Foundation restores payments after five-day pause, but worries over science funding persist
The NSF said on Sunday that its payment system was back on line, after it froze out researchers and sparked financial worries.

Hi, I'm Earyn, and I'm a lizard scientist! I created a game to teach people about lizards and increase the representation of Black women as herpetologists. #findthatlizard is a Where's Waldo-esque game where there is a lizard camouflaged in its environment. Your challenge is to find it. Will you? 🦎

The dismantling of American Science continues. The Organismal Response to Climate Change grant call has been cancelled. The NSF Director is a disgrace

Still frozen out. We’re getting word that people getting Universities to reach out to NSF over this & broader freeze may put pressure on them & help resolve this. If folks could start contacting their uni admin with complaints to forward to NSF (hopefully you know who to contact) it’d help a lot
To expand on this, right now ~200 postdoc fellows directly funded by NSF are locked out of their salary &research funds right before the first of the month. No doubt other NSF funded grads &postdocs are affected as well. All requests for funds put in before the freeze are slowly being cancelled
As of now, NSF does not appear to be changing course at all given the temporary restraining order or the rescission of the memo. I can't help but feel that the NSF director is failing us and his handling of this is indefensible. new.nsf.gov/executive-or...

As a NSF PRFB postdoc it would be nice to know if I can pay rent next month (crazy, right). In the meantime, for no reason whatsoever, here are a few ‘wasteful’ things I’ve done as a postdoc: been a science pen pal, helped run a booth at a science center, mentored a high school lab intern.

…the sentence at the end, “to the extent permissible by law, cancel awards already awarded that are in conflict with Administration priorities”.
Yesterday President Trump announced a pause on all federal grant disbursals. While it is a bit vague on details, it appears to include research grants. This would be devastating to American science. If you have not had a chance, call your Senators & Reps 🧪

Hyoids in action!
Woodpeckers are amazing creatures, with tongues up to a third of their body length, wrapped around their skulls in a way that looks... *anatomically wrong*

But I want to highlight some recent findings on how they avoid concussions.

Checkout this awesome preprint from @a-weberling.bsky.social et al. with the first description of early embryogenesis in the brown anole! This dataset was no small feat to collect as much of early development takes place before the egg is laid!! Thrilled to have been a part of this project! 🦎
