We mapped gene interactions across different environmental conditions (GxGxE) at scale for the first time in human cells. These maps lead to the realization that many genes function in a context dependent manner which provides insight into how humans have relatively few genes but many cell types. Congratulations Ben!

Happy to share our new work describing DESynR genes!
The evolution of new human protein-coding genes relies on repurposing protein domains from ancestral genes, rather than de novo sequence creation. New genes evolved from old parts, and while we have methods that enable high-throughput generation and screening of base-pair level sequence evolution (mutagenesis, directed evolution, CRISPR, etc), we lack similar scalable technologies for domain-level evolution.
We developed a high-throughput combinatorial molecular assembly method to generate thousands of barcoded novel genes from the domain building blocks of natural genes, termed DESynR (Domain Engineered via Synthesis and Recombination) genes.
excited to share COMET! A scalable CRISPR approach we (@carwils) developed to identify multidomain proteins that modulate transcription at specific endogenous genomic loci. @arcinstitute@ucsf

Our preprint reporting a multiAsCas12a CRISPRi platform for >3plex combinatorial targeting of genes and/or enhancers (including 6plex in high-throughput pooled screens) is now a peer-reviewed publication! https://t.co/upQfZJfNCQ.
excited about multiAsCas12a which we (@hsiung_chris) show enables 6plex CRISPRi functional genomics experiments @arcinstitute@ucsf

An incredibly sad loss of such an extraordinary woman and advocate. Susan transformed stem cell research and her legacy will continue with those touched by her vision for NYSCF.
With a very heavy heart, we announce the passing of our CEO and co-founder, Susan Solomon, following a long battle with ovarian cancer. We owe all that NYSCF has accomplished to Susan, and no words can express our gratitude and awe for her catalytic impact on stem cell research.
sci twitter q: what is the best way to manage scientific papers? What are the pros and cons of your pick? I'm a Papers user, but trying to decide if I should make a switch before beginning my phd!
thinking about my transition to grad school and the first thing I thought about this morning was whether or not I’ll have my own premium snapgene subscription
We have discovered a potent drug that blocks SARS-CoV-2 by a distinct mode of action: 1) EC50 ~ 80 nM by plaque assay; 2) it inactivates viral particles; 3) drug-treated coronavirus no longer binds to host cells. The drug is ethacridine. 1/n https://t.co/zrBi6qp5eK
