The classic CRISPR system cuts DNA. Other variants cleave RNA. But now in the toolbox of new biotechnologies may come a tool that targets proteins: a CRISPR-driven caspase, already dubbed Craspase. What remains constant is that all these tools are programmable, thanks to the guide molecule that recognizes the desired target and directs the scissors there for editing. They are not paper shredders, rather they act like scalpels.

Gender equity meets CRISPR

The Women in Enterprising Science Program (WIES) is located on the UC Berkeley campus and is supported by the foundation of Solina Chau Hoi Shuen (co-founder of Horizons Ventures in Hong Kong). The initiative, aiming to enhance gender equity in bio-entrepreneurship, was presented last March by IGI, the institute founded by Jennifer Doudna. In the pictures above you can see the inaugural cohort of fellows, announced this month.

Happy 10th Birthday CRISPR!

The seminal paper by Doudna & Charpentier was published online at the end of June 2012. The printed issue came out a few weeks later, on August 17 (don’t try to buy it, Science VOLUME 337|ISSUE 6096 is out of stock). No wonder the gene-editing community is in the mood for celebration these days. If you are too, don’t miss the chance to read these articles on CRISPR’s ten-year anniversary!

Have you heard of GEN Biotechnology? Issue 3 is already out, but I’ve just got my free copy of the inaugural issue (thanks!). Same publisher (Mary Ann Liebert), same executive editor (Kevin Davies), and the same passion for biotech frontiers as The CRISPR Journal. See below some crispy starters from issue number 1:

From the base-editing idea first sketched out via email in 2013, to the invention of prime-editing in 2019. From the progeria mutation fixed in mice in 2021 to the upcoming clinical trial for coronary heart disease. The updated story of the most advanced CRISPR tools told by Harvard’s David Liu is not to be missed (here’s the link to the Life Itself conference organized by CNN).
CRISPR WOMEN – faces and feats
They may have lost the latest round in the patent dispute, but Jennifer Doudna and Emmanuelle Charpentier will be forever celebrated as the inventors of CRISPR.
In “The Code Breaker” by Walter Isaacson, Doudna tells how a school’s guidance counselor tried to discourage her from studying chemistry at college: “Girls don’t do science.”
The Nobel prize came a few decades and many brilliant experiments later, it’s the first shared by two women. The institute founded by Doudna (IGI) is now launching an ad hoc incubator specifically to enhance gender equity in bio-entrepreneurship. Jennifer and Emmanuelle are unquestionably great role models for girls interested in science and started a wave of discoveries and inventions by female scientists.
In the slideshow below, you can meet some of the brightest women in CRISPR.
Be happy and CRISPmas on!

CRISPR rap: cut out misogyny and elevate the sisters!
Feng Zhang on how transposons hijacked CRISPR

CRISPR pioneer Feng Zhang walked through his current research projects at the national meeting of the Italian Genetics Association (AGI) on September 24. CRISPR associated transposases, retrovirus-like particles repurposed as delivery vehicles, the ancestry of CRISPR systems, and more. The first issue is probably the most fascinating. It’s actually amazing to see a new activity performed by some CRISPR systems: not to protect bacteria from viruses, but to help transposons jump into specific genome sites.
