Lovely little pre-Christmas present to see this out @natcellbio.nature.com! Some 🔥 new results in here since the biorvix incl (1) a new RARE-GFP reporter ✳️🙌, (2) additional NMP quantification 🔢, (3) no neural tube patterning on RA inhibition 🙅 etc. Enjoy! 😍 www.nature.com/articles/s41...

A parts list of promoters and gRNA scaffolds for mammalian genome engineering and molecular recording - @jshendure.bsky.social @troymcdiarmid.bsky.social @uwgenome.bsky.social go.nature.com/49eTPCu

Stoked to share our latest work entitled: “Large-scale discovery of neural enhancers for cis-regulation therapies” shorturl.at/H3Qww This is an enormous team effort that I had the honour of spearheading with Nick Page and Florence Chardon. Bluetorial below.

Thrilled to share I’ve started my lab at Dartmouth’s Geisel School of Medicine! We focus on mapping cellular trajectories & TF networks in development and Mendelian disorders, exploring new therapies. Join us—postdocs, grads, and scientists welcome! sites.dartmouth.edu/qiulab/

Super excited about first Shendure/Baker Lab collaboration & preprint on a multiplex sequencing-based strategy for screening de novo proteome editors in mammalian cells. Kudos to the brilliant Chase Suiter (not here) & @greenahn.bsky.social on the work! Preprint here: www.biorxiv.org/content/10.1...

💥🥳 At long last, our latest paper is out! Gag proteins of endogenous retroviruses are required for zebrafish development www.pnas.org/doi/10.1073/... Led heroically by Sylvia Chang & @jonowells.bsky.social A study which has changed the way I think of #transposons! No less! 🧵 1/n

1/n Wondering how transposable elements shape the evolution of cell lineage specification in embryogenesis? Please check this out! We found that human specific LTR2B can be bound by HAND1, transcribed and spliced into neighboring genes, most of which are human specific ExMC marker genes.

Great work from @zukailiu.bsky.social defining the first mesenchymal cells in human development as trophoblast-derived, and adding to the examples of evolutionary co-option of viral sequences contributing to our uniquely ape/human features. #hiPSC #MorPhiC #EvoDevo doi.org/10.1016/j.ce...

Our genome encodes > 7000 microproteins that have been previously ignored in genome annotations. How do these microproteins impact tissue function? Here, we use an in vivo single-cell CRISPR screen to systematically explore microprotein function in the mouse epidermis. 1/9

I can highly recommend the YEN 2025 meeting for students and postdocs working on 'anything embryo' - a fantastic meeting organized by students and postdocs for you!

Brief PSA for the functional genomics community: if you are profiling complex libraries with >1 internal components (e.g., enhancer+barcodes in MPRAs) delivered via AAVs, be aware that there might be substantial unlinking within your libraries if you packaged as a pool! doi.org/10.1101/2025...

Wonderful work! Congrats, Ryan!
