How much of the human genome is essential? Two pieces out today from our lab: 1) a method to map essential genomic intervals at gigabase scale, and 2) an argument that it's time to consider synthesizing a minimal human genome. biorxiv.org/content/10.6... nature.com/articles/d41...

We wrote a perspective "How to build the regulatory genome: a constructionist guide to the cis-regulatory code", out in Development yesterday. Title says it all. Find it here: journals.biologists.com/dev/article/...

We are hiring a staff member to support various projects in our lab. Please reach out with questions! wd5.myworkdaysite.com/recruiting/u...

Happy to share that our review on mammalian genome writing with Jack Atwater, Ran Brosh, Jef Boeke, @jshendure.bsky.social and Matt Maurano is now out in @cellpress.bsky.social! www.sciencedirect.com/science/arti...

Please 🔁! #MASSIV will be held in Vancouver from January 19-22, 2026. 4-day meeting on #synbio x #tissueengineering. Some trainee-focused events. >50 talks (10 from abstracts), posters, panel & publishing insights sessions. www.massivconference.com Abstract deadline: Nov 14

Please RP! A 4-day synbio and tissue engineering conference #MASSIV to transform biology and medicine together. Couldn't list all amazing speakers, so please check out this 👉https://www.massivconference.com/ Poster due is Nov 7, but will be extended. With @stemcellnetwork.ca and JST.

New paper from my lab and @jshendure.bsky.social lab! Led by the brilliant @zukailiu.bsky.social and @cxqiu.bsky.social. We tackled how anterior and posterior progenitor cells cooperate to self-organize into an embryonic structure (termed AP-gastruloid). (1/n) www.biorxiv.org/content/10.1...

We are hiring a scientist to lead our 'Build' team at the Seattle Hub for Synthetic Biology. @alleninstitute.org Job posting below: alleninstitute.org/careers/jobs... Please reach out if you have any questions!

The nuclear lamina strengthens the nucleus and organizes the genome. So what happens when you acutely degrade it in living cells? Not what we thought! (1/n) www.molbiolcell.org/doi/10.1091/...

Excited to share our work with @julietrolle.bsky.social & Jef Boeke. We developed a 'shotgun' method to screen millions of synthetic metabolic pathways to enable mammalian cells to grow without two essential nutrients for the first time in >500 million years! doi.org/10.1101/2025... Thread...

Our paper describing the Range Extender element which is required and sufficient for long-range enhancer activation at the Shh locus is now available at @nature.com. Congrats to @gracebower.bsky.social who led the study. Below is a brief summary of the main findings www.nature.com/articles/s41... 1/

CAGT was fun! Thanks @carldeboer.bsky.social @sudpinglay.bsky.social and the de Boer lab for organizing! Folks from Seattle, Oregon, and other places. Great community. Arman gave a usual super talk, and Sanchit and Dayag won poster prizes☺️

CloneSelect published in Nature Biotechnology @natbiotech.nature.com. This retrospective clone isolation method using CRISPR base editors is a powerful tool in broad biology. A history of Soh in the Yachie lab. www.nature.com/articles/s41...

Need a site-specific, dox-inducible system for human cells? Low leakage, silencing-resistant, and modular? It’s here in the first paper from my lab, led by Tomoki Yanagi MD, PhD. Bonus: forward programming of TEC-like cells from hiPSCs. tinyurl.com/trunod01

We are hiring a person to join our team at the Seattle Hub for Synthetic Biology. Please share the word! Link to apply: alleninstitute.org/careers/jobs...

Check out this video explainer of our recent paper on shuffling mammalian genomes. Thanks to Jeremy @genometdcc.bsky.social for putting this together!

@science.org Genome recombination on demand | Science www.science.org/doi/10.1126/... a Perspective by @seczmarta.bsky.social Lars Steinmetz @stanford.edu on two studies bit.ly/4hzFRMg + bit.ly/4jyT4Hf that generate large genome rearrangements in mammalian cells @ unprecedented scale #synbio #genome

Read thread below, if you want more details on the personal side of this wonderful collaboration.

Now out in @science.org w/ @jshendure.bsky.social we present 'Genome-shuffle-seq': a method to shuffle mammalian genomes and characterize the impact of structural variants (SVs) with single-cell resolution in one experiment. www.science.org/doi/10.1126/...

The Chan Zuckerberg Initiative is awarding BBI researchers $1.5 million over two years to “democratize” access to synthetic DNA. We are envisoning complementary technologies that address shortcomings of current systems for manufacturing DNA. brotmanbaty.org/news/chan-zu... @sudpinglay.bsky.social

By definition, enhancers can activate from a distance. But with increased distance between enhancer and promoter, the activation drops. To study this systematically, we build a synthetic locus: www.cell.com/molecular-ce... 1/12

Gene regulation involves thousands of proteins that bind DNA, yet comprehensively mapping these is challenging. Our paper in Nature Genetics describes ChIP-DIP, a method for genome-wide mapping of hundreds of DNA-protein interactions in a single experiment. www.nature.com/articles/s41...
