For #FluorescenceFriday, an E10 embryo showing Pax2 localization. #DevelopmentalBiology

Our first cancer biology preprint is up! TRIM9 switches melanoma cell phenotypes. First author @klukasik.bsky.social has taken the lab into new directions for sure in a fun collaboration with @coronin.bsky.social. We can't wait to hear what you think. www.biorxiv.org/content/10.6...

Happy to share scHiCAR, an ultra-high throughout (millions of cells), low cost (5 cents/cell including NGS), and trimodal platform for integrated single-cell level analysis of mRNA, open chromatin, and 5-kb resolution looping with ground-truth data the same individual cell.

A blue Tulip (Sustentacular cell) behind some red (OMP) OSN cell bodies, and some green horizontal basal cells in the olfactory epithelium. Stylized for a science art presentation (easier to find than original).

An old favorite for this #FluorescenceFriday. This "rose" is actually a kidney glomerulus (red, podocytes) and an axon reaching towards it (green).

When your cat is obsessed with #PuppyBowl. As a special needs adoptee herself, she’s a huge advocate.

I am very excited to visit NC State this weekend and give a seminar on Monday! I'll be in Raleigh from Saturday to Tuesday so I'm joyfully accepting all running trail suggestions, dining ideas, cool places to sit and write 6 R01s, and any friends who want to say Hi! gga.ncsu.edu/event/tim-mo...

Great things still happen all around us. Each your UNC Biology's Bob Goldstein and Art's Beth Grabowski co-teach ARTS/BIOL 409, that brings together artists and scientists to explore an intersection of two disciplines. It culminated this year with a remarkable show Friday 1/n

Pro tip: NEVER log into My NCBI with more than one 3rd party option. It creates a whole new account that can’t be deleted. I apparently did this once with the ORCiD login (as opposed to normal eRA login) and now I can’t link my ORCiD ID to my SciENcv. I have to ask the Help Desk to merge accounts. 🫠

Introducing Cyclically Multiplexed Expansion Microscopy (Cy-ExM): a workflow for 3D nanoscale, high-plex imaging in whole cells. Cryo-preserved ultrastructure + iterative labeling + expansion microscopy → 20 targets in one dataset with ~70 nm lateral resolution. www.biorxiv.org/content/10.6...

It’s certainly been a year, but I’m incredibly grateful that earlier in 2025 I was promoted to Associate Professor with tenure! Huge thanks to you all for promoting our work here and on the other site, for talk invites, for writing letters of support, and to the lab for all their contributions. 🥂

Unfortunately the drop in ESI funding rates is not paired with changes in funding required to get tenure. It’s not just the next three years of our labs at risk, but the rest of our careers. We are also the cohort that started in the COVID pandemic- it’s been nothing but “unprecedented times”…

Most transcriptomics studies sample ~0.001% of a mouse. Which region do we choose? Often: we guess. Meet DISCO-seq 🤗 flipping the order: RNA-preserving clearing → whole-organ/whole-body 3D imaging → pick ROIs in 3D → unbiased scRNA-seq. Preprint: www.biorxiv.org/content/10.6...

In a paper out this month in @jcb.org we present evidence implicating intrinsically disordered regions (IDRs) as key to junctional assembly and function 2/n 🧪 pubmed.ncbi.nlm.nih.gov/41099653/

Our new work Cilia.io is out on the Rxiv. Ece Atayeter and Jason Ho trained an ML computer vision transformer for detection and quantification of cilia morphology and dynamics. We will provide a GUI soon. Another great collaboration w/ @jbwallingford.bsky.social

🚨 Preprint Friday! 🚨 Thrilled to highlight this collab with David Brown at Duke @cutitoutdave.bsky.social and Ken Poss at UW Madison/Morgridge @kenposs.bsky.social. By comparing 3(!!) regenerating models we identify a conserved role for Sp-family TFs in appendage regeneration (and more).....🧵

UNC's Center for Molecular Medicine has up to three open-rank positions for faculty conducting research with relevance to gene therapy, including: novel iPSC and animal models of disease and basic cell biology. Join us in beautiful Chapel Hill! Deadline 1/31/26: unc.peopleadmin.com/postings/309...

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)

Sensory neurons drive pancreatic cancer progression through glutamatergic neuron-cancer pseudo-synapses @cp-cancercell.bsky.social www.cell.com/cancer-cell/...

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...

WATCH: Elephants at the San Diego Zoo Safari Park react to Monday's 5.2 magnitude earthquake that shook San Diego County. The elephants formed an "alert circle" meant to protect the young and the entire herd from any threats, according to the San Diego Zoo Wildlife Alliance.

Finally out! Brittney Voigt et al show the shared role of Inppl1a expansion of notochord vacuolated cells and also for hypertrophy of chondorcytes and bone lengthening. @currentbiology.bsky.social www.cell.com/current-biol...

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.
