Crazy 4 Prime Editing

Great piece of science by the Liu Lab in Nature, describing the brand new “Search-and-replace genome editing without double-strand breaks or donor DNA”. How is the CRISPR community reacting?

Best quote: “One of those ‘Yay, science!!!’ kind of moments” (Fyodor Urnov quoted in Science)

Most ironic: “Congratulations @davidrliu. We’d probably have published this paper as well (The CRISPR Journal tweet)

Best title: Genome Editing Heads to Primetime (Genetic Engineering and Biotechnology News)

Most understated: A New Gene Editing Tool Could Make CRISPR More Precise (Smithsonian Mag)

Most hyped: A New CRISPR Technique Could Fix Almost All Genetic Diseases (Wired)

CRISPR evolved in bacteria as a defense mechanism against viral infections. But now researchers are turning the same weapon against bacteria themselves, hoping to defuse antibiotic resistance, which according to WHO is one of the biggest threats to global health.

Here is a semi-serious selection of the things that I liked the most in the documentary by Adam Bolt (please see the gallery’s caption to know why)

The CRISPRmobile driven by Rodolphe Barrangou (the CRISPR journal’s editor-in-chief); Fyodor Urnov’s communication skills (and t-shirt); Francisco Mojica replaying his seminal experiment in Spain; Alta Charo’s Star Trek-inspired bio-optimism; Vladimir Putin representing the voice of bio-pessimism (“it may be more terrifying than a nuclear bomb” he said at the World Youth Festival in Sochi, 21 October 2017); Ruthie and David playing basketball while their relatives worry about their health problems; last but not least the movie’s real star, the gorgeous Cas9!

The ethics of using CRISPR to improve the odds of savior siblings. This is when a couple tries to have another baby who is both healthy and a suitable donor “match” for their older kid (“Could editing the DNA of embryos with CRISPR help save people who are already alive?“, STAT News, Sept. 16).

Carl Zimmer explaining a CRISPR experiment carried out to understand why many cancer drugs fail (“Why Aren’t Cancer Drugs Better? The Targets Might Be Wrong”, New York Times, Sept. 11; see also the paper in Science Translational Medicine)
