The regulation and evolution of proportion is a classic challenge in biology. This is exciting work into the genetic and developmental basis of proportionality using a very cool model. Congrats Ceri! 👏🧪🧬🐭

Vertebral skeletal diversity in mammals is remarkable. How do the differences between vertebral size and shape develop and evolve? See how we tackled this question in our paper published in @natcomms.nature.com today!

Hey maybe jerboas are also big and dangerous sons of bitches!

Thank you to all the authors and network of colleagues and mentors who have helped make this work happen. I can't wait to keep digging into vertebra development, axial skeletal diversity, and tail biology!!

Here, we use the jerboa and mouse to understand the temporal growth dynamics that establish adult vertebral proportion, the cellular drivers of differential growth, and candidate genetic mechanisms that determine and diversify vertebral proportion.

Cellular and genetic mechanisms that shape the development and evolution of tail vertebral proportion in mice and jerboas - Nature Communications

Vertebra lengths differ from the neck to the tail tip and differ between species, evidenced by extreme differences in mouse and jerboa tails. Here, Weber and colleagues identify cellular mechanisms and candidate genes that shape vertebral proportion.

We find that their long tails are acquired by far greater elongation of individual vertebral elements in the mid-tail region. This pattern, called a 'crescendo-decrescendo' of tail vertebral lengths, likely enhances their ability to inertially maneuver. See: pmc.ncbi.nlm.nih.gov/articles/PMC...

This project started during my postdoc interview when I asked @ucsdcooperlab.bsky.social "jerboa tails seem longer. Have you looked into that?". It turns out the jerboa tail is approximately 1.5x longer than the mouse, normalized to body length, but with 3-4 *fewer* vertebrae than in mice.

I love degus!! They have sweet little medium tails, and a few features that I'd love to study. That 90 day gestation is LONG but it looks like they're born precocial so I may not always need to wait 3 whole months...

I'd love to study tree squirrel tails but that particular side quest has been benched for the time being.

By short(er) I mean anywhere from shorter than the length of the body (nose-anus) to a stubby little guinea pig tail. I'm already looking at mouse tails (1x its body length) and jerboa tails (1.5x body length).

Bsky brainstorm! I'm looking for a short(er)-tailed rodent amenable to embryological research (timed pregnancies, decent litter size, easy to get/breed enough to sacrifice dams, etc).

This is SO cool and was such a fun read this morning. Congrats to the whole team!!!

Are digits modified fins, or evolutionary innovations? Read how we tackled this old question from a new angle🧪

Side hustle level-up! My book, IN THE BEGINNING, will be published by @harperonebooks.bsky.social in 2027! It's about the human embryo, how it gets built, and what it means for where we come from and where we're going.

It's chilling to hear my Dad's voice in Eric Dane's, knowing that ALS has reached his respiratory muscles and how heartbreaking it must be for his loved ones to watch the disease progress. I admire how @iamals.bsky.social approaches ALS research, treatment access, and outreach, so please amplify:

iamals.bsky.social @iamals.bsky.social · 29d

We're launching our Push for Progress campaign to accelerate ALS research, expand treatment access, & secure $1BN in federal funding over 3 years. ALS is at a tipping point CLOSE to new treatments, but thousands will lose access unless we TAKE ACTION @ iamals.org/progress

We take for granted that our hands have two sides and can articulate in an endless number of ways. But what about a fish’s fin? Can a fish know something “like the back of its fin,” or have its future told with a fin palm reading? Check out this bluetorial to find out 👇🧪🧬🐟 doi.org/10.1101/2025...

This is insane and so wrong. This cohort of 2020 postdocs, who are now largely also job search ready in this market(?), keep getting screwed.

NIAMS just announced K99/R00 extensions, which is fantastic for trainees impacted right now, BUT I’d like to point out that the *only* postdocs who did not benefit from COVID extensions and are ineligible for the new extensions are those who started in 2020 lockdowns.
