• Limb loss triggers a body-wide activation response that kickstarts regeneration • This response requires sympathetic innervation and adrenergic signaling • Uninjured distant tissues keep a "memory" of the amputation so they can respond more quickly if they are later injured

There are several cool findings:

Axolotls use adrenaline signaling to regenerate legs! Today, we can finally share the official publication of a really exciting project we've pursued over the last several years. Thanks to the entire team for their creativity, expertise, and work.

Have you ever met a kid who doesn’t have a zillion questions about axolotls? I know I haven’t. That’s why I wrote this book! With super cute and accurate illustrations by @LordABethany @MacKidsBooks @neonsquidbooks https://t.co/FoMI67UXHW

Congratulations to Igor on leading this proposal! We are very excited to work with your lab and Max’s lab on this very cool project! @_ischneider_

Thank you to Alie Ward @Ologies for giving me the opportunity to talk about how we—and others—are using axolotls to understand how regeneration happens, and so much more! And thank you to her listeners for all the great questions 😊 https://t.co/SbdQG0yYHh

Thrilled to share our cross-species study of TG and DRG cell types in published form! This was a collaborative effort led by @shamsChronicles and @MengyiXu4 across many groups including @robgereau, @UTDPainLab, @rezasharif,@JessLaMae, and Clifford Woolf https://t.co/kPGJLtBZa7

Excited to share my first postdoc study, titled “Harmonized cross-species cell atlases of trigeminal and dorsal root ganglia”. https://t.co/p1JGo2mjZ5 1/n

Congratulations to @HSCRB @BBS_Harvard grad student @nojaalopez, who just got the NSF GRFP! We're all so happy for you, and I can't wait to see where your PhD research takes you!

I've gotten so many emails from kids lately that I'm hosting a live Q&A for grades 4-6 to answer all those burning axolotl questions! Teachers can contact me for a Zoom link (email below). Feb. 2, 9-10am Eastern.

Our department is hiring a new Assistant Professor to establish a research program and teach on the Harvard campus in Cambridge, MA! We encourage anyone interested to apply and to reach out if you have questions about the app. #embryology #stemcells #regeneration #development

Anyone in the Boston/Cambridge area have some Cas9 protein they can spare? We can bring you some replacement as soon as our order arrives or swap for something else. We usually use MacroLab/Berkeley’s Cas9-NLS, but we’d try another vendor.

Congratulations to Dr. Duygu Payzin-Dogru (pictured with stuffed axolotl) on the successful defense of her PhD thesis today! @duygupayzin @BBS_Harvard

We have a spectacular list of speakers lined up, including keynotes from Caroline Beck @Frog_squisher, Cliff Tabin, and Neil Shubin @NeilShubin!

Anyone thinking about joining us in Cambridge, MA, USA, for the (usually bi-annual) 16th Limb Conference—please check out the site here for details. Registration closes June 30.

Reminder: abstracts and travel award apps are due soon—May 31.

Hope to see some old friends and new colleagues here this summer
