Twenty-one years after genome 1.0, the Telomere-to-Telomere Consortium gives us a new assembly (T2T-CHM13) generated by long-read sequencing. It adds approximately 200 megabases of accurate genetic information, roughly equivalent to a whole chromosome. As Deanna Church writes in a perspective it is “an important step to assembly models that represent all humans, which will better support personalized medicine, population genome analysis, and genome editing”. Dont’s miss this Science issue!
“Science in times of war: oppose Russian aggression but support Russian scientists” is the heartfelt article recently published by Eugene Koonin in EMBO Reports. Koonin is a leading evolutionary molecular biologist and a CRISPR pioneer. Born and raised in Moscow, he left the USSR a few weeks before it dissolved in 1991 and moved to the US where he works at the National Center for Biotechnology Information (NCBI-NIH).
He was elected Member of the National Academy of Sciences of the USA in 2016 and Foreign Member of the Russian Academy of Sciences (RAS) in 2019 but resigned from the second one at the end of February this year. You can read why in the excerpt below, and learn more about his outstanding contribution to science and the CRISPR field in this PNAS profile.

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.
Nature was right in choosing CRISPR diagnostic as one of the seven technologies to watch in 2022. The latest news is a test called mCARMEN, described in Nature Medicine. Pardis Sabeti (Broad Institute/Harvard), Cameron Myhrvold (Princeton University) and colleagues adapted a massively multiplexed technology presented in 2020 to be “faster, more sensitive and more easily implemented in clinical and surveillance labs”.

Engineering lymphocytes to recognize cancer cells is a strategy that has already produced convincing clinical results thanks to CAR-T therapy. But this is not the only approach on the horizon. An emerging alternative is TCR-engineered lymphocytes, where TCR stands for T-cell receptors.

Two papers and a news item not to be missed. The first one is “Genome-edited powdery mildew resistance in wheat without growth penalties” published in Nature by a Chinese team led by Caixia Gao.

Doug Olson was treated with engineered T cells (CAR-T) for incurable leukemia in 2010, well before CRISPR was born. Over a decade later, he still is cancer-free (see the paper in Nature), and the pioneer of the approach, Carl June, is reported to have said the C-word: cured. As immunotherapy and genome editing are crossing paths, hopefully, we expect further good news from the CAR-T frontier in the future.
The first paper on a CRISPR xenotransplant is out in the American Journal of Transplantation. It’s about two swine kidneys with 10 modified genes transplanted into a dead brain man as a proof of concept. The surgery was performed on September 30 by Jayme Locke and colleagues from the University of Alabama at Birmingham.

If you like healthy food and biotechnology, you’ll love the news. Japan has given the go-ahead to market two CRISPR-edited fishes: a tiger puffer and a red sea bream, both developed by Regional Fish Co. together with Kyoto University and Kindai University.

As you probably know, on January 7 at the University of Maryland Medical Center in Baltimore a 57 years old man named David Bennett became the first human to have his heart replaced with that of a CRISPRed pig. But what does make a xenoheart suitable for transplantation?
