Some good news: @hannahhrncir.bsky.social ‘s primary PhD paper is finally online! This study lays the groundwork for a lot of technical and conceptual things the lab is currently working on, including light sheet microscopy for imaging entire biliary trees in mouse liver: rdcu.be/d90Br 1/4

This was a fun lesson in having your hypothesis proven wrong (we thought they would have worse outcomes after injury), and having that be even more exciting. We hope what we find may help inform tissue engineering and regenerative strategies, and lead to improved clinical interventions.

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....

It’s a quill? A sea pen? No—it’s a gill filament! 🪶🪸🐟

Under the microscope, this fish gill structure looks just like a sea pen.
Fascinating how nature keeps circling back to the same shapes.

Organ sculpting cells may hold clues to how cancer spreads

A new study from scientists at the University of North Carolina at Chapel Hill reveals that the cells shaping our organs may be far more mobile and coordinated than once believed.

My full story about the court's ruling today, which @scott-delaney.bsky.social called an “extraordinary repudiation” of the Trump administration.

The judge ruled the “whole enterprise was rotten to its core” by declaring the “ideas that animated the policies” illegal, he told me.

Judge rules against NIH grant cuts — and calls them discriminatory

The decision means that the US biomedical agency has to restore funding to hundreds of research projects, but the government will likely appeal.
