We present multi-immersion Oblique Plane microscope (miOPM), a light-sheet platform that can be adapted to a wide range of applications, from sensitive live cell imaging to imaging organs and cleared tissues.

Wrong place, right time: Eda drives ectopic teeth formation in fish
This Research Highlight showcases the work from Tyler Square and colleagues: journals.biologists.com/dev/article/...
Eda overexpression causes precocious tooth differentiation in sticklebacks. (A,B) at 9 dpf, Eda OE fish (n=9) demonstrated precocious oral tooth germs relative to control fish (n=10). Images show eGFP from the dlx2b tooth reporter and mCherry from the OE transgene. A’ and B’ show the fish indicated in A and B in greater detail. Black arrowheads indicate pioneer tooth germs. (C) at 12 dpf in WT, pairs of germs are observed on the premaxilla and dentary (black arrowheads), similar to the condition seen in the 9 dpf Eda OE fish, suggesting these represent accelerated endogenous teeth. Sale bars=100 μm.

Our latest preprint! Into morphogenesis, Yap, ECM, signaling, vertex models, feedbacks/robustness? There is something here for everyone. We discovered a positive feedback loop that extends inner ear canals, and a built-in mechanism that shuts it down when morphogenesis is done. tinyurl.com/464wsjhd

Cancer cells are notoriously plastic, but what triggers the changes in cell state? In our new Nature (@nature.com)‬ paper, Miranda Hunter (@mrndhntr.bsky.social‬) found that mechanical pressure is a key to this switch. Check it out here: go.nature.com/47iwDm2

Check this neuron infected with #SARSCoV2 being attacked by a microglia. Is this process beneficial or detrimental? Do we want therapies to inhibit microglia activation/neuroinflammation, but what if it means more neurons infecting other neurons? Neurovirology is fascinating! #FluorescenceFriday

mRNA tech is some of the coolest, most powerful, most promising scifi shit humans are currently doing. They are being investigated to help with cancers, autoimmune diseases, M.S., stroke recovery, heart disease, diabetes, arthritis, and high cholesterol.

New short story from my postdoc in the Bassler lab is up on bioRxiv!

Turns out our favorite quorum sensing responsive phage VP882 is a member of a larger family of phages that is distributed across multiple bacterial species and can eavesdrop on a universally conserved autoinducer.

Hey friends - Daniocell is experiencing a temporary outage right now. The NICHD server it is hosted on got dropped from the NIH’s firewall list & so currently can’t be accessed outside the NIH. The relevant IT teams are working to resolve it. Sorry for any inconvenience. It’ll be back soon!!

I doubt that there is a single family in America that hasn’t benefitted directly from the NIH.

Our latest issue is now live! On the cover is a species of Asian noodlefish characterized by their transparency due to the absence of red blood cells, slender bodies and scaleless skins, and a poorly ossified skeleton. www.cell.com/current-biol...

I might be a bit obsessed with blood vessels in the brain 🤓! Aren't they pretty? And check the red blood cells inside the small ones!
Is it okay if I keep advertising our call for papers using more images of blood vessels in the brain? 😜🔬
