Since the discovery of CRISPR-Cas systems, people have wondered if a similar type of system exists in eukaryotes. Today, we report in @Nature the characterization of Fanzor, a eukaryotic RNA-guided system that can be reprogrammed for human genome editing.
Fanzor is a eukaryotic programmable RNA-guided endonuclease

We are excited to share STOPCovid, an inexpensive, one-step, & sensitive #COVID-19 detection protocol developed with @omarabudayyeh & @jgooten. This revamped assay was streamlined with the future goal of developing an in-home test for COVID-19. zlab.bio/s/COVID-19-det… 1/X

CRISPR technologies are powerful gene editing tools because they are programmable. We are excited to describe 3 new programmable systems, IscB, IsrB, and TnpB, some of the most abundant genes on the planet, with potential for gene editing. @ScienceMagazine science.org/doi/10.1126/sc…

Our genomes are littered with *junk* DNA known as LINE retrotransposons, which are powerful enzymes that can insert DNA into the genome. We are excited to report the structure of the LINE family member R2 and ways to engineer it for programmable gene insertion. Congratulations to

How do LINE family retrotransposons jump around? Can we reprogram retrotransposons? What does this have to do with Rum and Raisin? Answers here and below!

We are excited to report the discovery of TIGRs, a widely-occurring RNA-guided system found in bacteria and their viruses. TIGRs consist of a peculiar repeat region which is transcribed into RNA and processed into multiple guide RNAs to direct TIGR-associated proteins to their

Today we are sharing a research protocol for SHERLOCK-based COVID-19 #coronavirus detection, and hope it will help others who are working to combat the outbreak. We will continue to update this as we make further progress: static1.squarespace.com/static/5b7c640…

Thrilled to announce our latest exploration of CRISPR! By developing an advanced algorithm, we’ve analyzed 8 terabases of microbial data, leading to the discovery of over 200 novel CRISPR systems. Kudos to @altaetran and @soumya_kannan12 for their exceptional work! Details in the

Our latest work exploring ultra rare CRISPR systems with new big data algorithms has been published by @ScienceMagazine! @zhangf @soumya_kannan12. This thread will unwrap how we found needles in a haystack of metagenomes. Let's dive in! (1/8) doi.org/10.1126/scienc…

CRISPR systems are quite diverse, including some, like CRISPR-Cas13, which target RNA. @soumya_kannan12 & @altaetran found tiny versions of Cas13b (Cas13bt) that can be used to create RNA editors small enough to fit into a single AAV for in vivo delivery. nature.com/articles/s4158…

Did you know there are lots of similarities between the innate immune systems of animals/plants and the phage defense systems in bacteria? Check out our new study by the amazing trio Alex (Linyi) Gao, @maxewilkinson, and @thestrecker. Congratulations! science.org/doi/abs/10.112….

My favourite discovery ever has just come online. Can I please tell you about some seriously wacky molecular biology? The story starts with a reverse transcriptase that SOMEHOW defends bacteria from viruses. (👇 I recommend sound ON for the video 🎹) 1/
