Sharing this excellent review now out from postdoc Sarah McLarnon! Lots of useful info on 3D imaging, quantification of imaging data, and how this has been applied to the kidney. And since it's #FluorescenceFriday, sharing a figure with our own imaging data! www.sciencedirect.com/science/arti...

Rescued these two beauties today, one stuck in the parking garage stairwell and one from inside the house (and rescued from 3 very interested cats)

This is me, one of those 211. My A1 R01 renewal would have been funded otherwise, and I was even initially told they planned to fund it. Now very unlikely. No more chances with this one. We had so many good things going-how do we keep moving forward? A question many of us will be asking.

How can cells self-organize rapidly into complex patterns during development? Let’s explore a powerful and underappreciated mechanism: Directed Cell Migration (DCM). Preprint @biorxivpreprint.bsky.social : doi.org/10.1101/2025... 👇Thread 🧵(1/11)

Intermediate mesoderm isn't the sole contributor to nephrons in zebrafish-new manuscript out showing somites are a source of nephron progenitors! Very cool, dogma challenging study led by Alan Davidson's group. Many fun discussions were had-grateful for the inclusion! www.nature.com/articles/s41...

New, from an anonymous NIH insider: Trump is being pushed to spend more NIH money. The White House is ordering NIH to do multi-year budgets for awards. This budget trick means fewer awards, fewer labs funded, and lower paylines for researchers. 🧵 donmoynihan.substack.com/p/alert-the-...

The NIH was healthiest when pay lines were in the 20th percentile range. We are headed into an environment where pay lines are in the 5% range. In my entire career, I’ve only had 3 grants that scored better than 5%. And my lab is considered a successful one. This is going to destroy science.

A beautiful tour through an AAV-PHP.B-GFP-transduced intact cochlea as visualized via lightsheet microscopy after tissue clearing. Magenta is a hair cell marker, yellow is a neuron marker, and green is AAV-GFP (relatively low hair cell transduction rate in this specific sample).

#FluorescenceFriday! Thanks BPoD!

Surprise catch while surf fishing! No baby sharks harmed, was safely released back into the ocean. 🦈

For #FluorescenceFriday I'm sharing the fantastic work of postdoc Sarah McLarnon! A follow up to our '23 Development paper where we asked: Does precise vascular patterning matter for function and what happens after ischemic injury? The results were surprising! journals.physiology.org/doi/full/10....

Evening visitor to the feeder showing off the ruby throat 😍

Check out the latest from Alan Davidson’s lab (of zf kidney regeneration fame) showing somites contribute to making nephrons in zebrafish. GESTALT, Cre lineage tracing, and zf somite transplants 😱. Love a good story that challenges dogma. Great discussions were had! www.biorxiv.org/content/10.1...

20 minutes ago here in Venetie, Alaska, the skies erupted in a beautiful auroral substorm. Here is just one of many real-time videos I recorded during the show to give you a sense of how fast and dynamic the aurora can move.

A friend drove two hours today for her breast cancer chemotherapy only to learn it was canceled due to NIH cuts. Clinical trial ended midstream. No treatment, no restart, no plan, no information. Her bro-in-law's chemo was also canceled.

Exciting work from the UNC Kidney Center this week: pubmed.ncbi.nlm.nih.gov/40020049/. Posting because we don't have an official account here (yet), but some excellent folks in our lab discovered important steps in the mechanism by which hydrANCAzine causes...well.. ANCA! #NephSky #MedSky 🧵

Congrats to @llobrienlab.bsky.social on winning an Innovative Science Accelerator Award from @isackuh.bsky.social! She pioneered whole tissue 3D imaging of #kidney nerves. Now she will map changes in these nerves from acute injury to chronic disease for the first time! med.unc.edu/cellbiophysi...

🔬🎤 As pre-announced a few days ago... please let us proudly present to you: 𝑴𝒊𝒄𝒓𝒐𝕊𝒑𝒍𝒊𝒕 - your ticket to imaging more, imaging more gentle, and/or imaging more efficient. 🔬 doi.org/10.1101/2025... Like ❤️, repost 🔂, and most importantly... please send feedback ✉️ our way! 🙏

I am actively looking for a research scientist position or research administration role within the Raleigh-Durham (RDU) area! Please reach out if my background and skillset might fit your labs needs :-) Lots of experience with preclinical models, translational neuroscience, and behavioral analyses!

🎉 Happy Valentine's Day, we love you science! ❤️ #FluorescenceFriday #sciart #neuroart

Congratulations to my PhD student Ike Emerson for showing sex differences in the heart are regulated through X-linked miRNAs and a big thank you to Bill Marzluff! www.ahajournals.org/doi/full/10....

A huge effort and amazing advance by this team! Check out the preprint link below. We were amazed with what we could get out of our samples (those are our kidneys below!). Major thanks to @kevin-dean.bsky.social for including us.
