The picture shows a moment in the sample-collecting effort leading to this Pnas paper about a novel heat-tolerant CRISPR enzyme called IgnaviCas9. Exploring nature’s molecular diversity in extreme environmental conditions such as Yellowstone hot springs can yield exciting discoveries and applications.

The analysis of tweets discussing CRISPR from 2013 to 2019 shows that public enthusiasm for genome editing has cooled a bit, and that’s physiological. As you can see below, a bioRxiv paper associates peaks of strong negative sentiments with specific events.

China is the “Innovation Nation” and “The next biotech superpower”, according to the November issue of Nature Biotechnology. Beijing is “set to challenge the pre-eminence of the US drug market. If it can address gaps in its R&D ecosystem and clinical infrastructure, it may even become a home for biotech innovators”, says the editorial.

I binge-watched Unnatural Selection, as many CRISPR enthusiasts have done. My review in a few words: the Netflix miniseries is a patchwork of bad and good. On the minus side, too many biohackers and too little real science. On the plus side, some interesting reporting on social issues, such as public engagement of local communities and the challenge of patient access to novel therapies. To sum up: episode 1 on biohacking is the worst, episode 3 on gene drives is the best. So my advice is: don’t give up at the first disappointing scenes. You might want to, but do not stop.
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?

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.
