Our work on the evolution of the regulatory genome of echinoderms is now out in @natecoevo.nature.com. Led by my former PhD Marta Magri, Danila Voronov & Saoirse Foley. Great collaboration of Arnone, Hinman & Maeso labs, started long time ago with our missed José Luis Gomez-Skarmeta: rdcu.be/eXX8l
Deep conservation of cis-regulatory elements and chromatin organization in echinoderms uncover ancestral regulatory features of animal genomes

As it goes with some experiments where we don't know the answer, my PI and me likes to do a little bet on if we will see a phenotype or not after I am done staining this... My PI is definitely more willing to gamble than I am 😀

My PI did his magic and helped me get the ndr2.2 fish to breed (they are old and I havent been able to get them to lay since November). Well now there are 12 embryos and we are praying that at least 1 will be a mutant 🐟 May the zebrafish Gods bless us tomorrow, we shall see

Our research on reptile pigmentation is featured on the cover of Genetics 🧬🦎
We uncover how mutations in TYR, SLC24A5, and OCA2 shape hypomelanism in snakes & geckos, revealing modular and flexible melanogenesis.

Today i discovered my height of 5'2 was actually perfect to do bench work without straining my back. My lab mates proportions and height means they have to bend down at an angle and crane their necks 😭 I guess I can't stay mad when the scope chairs keep on changing in setting....

Visited St Louis zoo again yesterday and got to see the amur leopard and cheetah cubs :) They are so cute! Sadly the big ungulates and the asian elephants were all not in their enclosures. I imagine it was cold. I wish I got to see the baby asian elephant again but next time

American Robin in his full-on winter plumage in St Louis! He was big backing the berries and a female robin who I suspect was his girlfriend was also hanging out nearby.

Thinking if I should take the L and just buy an Adobe Illustrator subscription for myself to make figures or try to bug WashU to give me a free one (idk if they do that)

So our fish facility mixed up and lost our mutant fish line that we imported 🥲 My PI broke the news to me by saying "there is a little bit of a curveball to our schedule....."

I'm trying to breed Chocolate/Cinnamon back into my lines for this silly cat breeding game but its so hell 😭 I can't remember who might be carrying the recessive

I love seeing some awesome work done on Ciona this year in dev bio 🥺 I can't wait to see more. Here at St Louis we have two Ciona labs so far, and they're doing some cool stuff
Very happy to see this piece on the Tunicate Ciona published. Grateful to @alexandrejan.bsky.social and @chiaracastelletti.bsky.social for the Illustrations, and to @natmethods.nature.com for the opportunity to showcase our ever emerging model organism www.nature.com/articles/s41...

So I found some dry fish at the bottom of my lab's cabinet outside and started munching on them, only to discover that they've been expired a year ago, but it's okay because it's dried fish. Kept on munching on some more.

Chimps maybe being more rational than some people I know.
The ability to change your mind in response to better evidence is a hallmark of human cognition. Experiments now show that chimps are capable of rational thought too

I'm actually very curious about science illustrators--especially those who makes reconstructions based on fossils. Like what do you guys do? How did you get there?

New T-rex with short king energy just dropped 🦖👑
A newly described fossil strengthens the case that more than 66 million years ago, western North America was home to two genera of tyrannosaurs at the same time: the larger apex predator Tyrannosaurus rex and a smaller predator known as Nanotyrannus. https://scim.ag/3XrHvrf
Mini-tyrannosaur lived alongside T. rex, extraordinary fossil confirms
Study finds fresh evidence for Nanotyrannus, a dinosaur whose existence has long been debated
