European scientists must wait for the EC to carry out targeted consultations with Member States and EU-level stakeholders. Then the Commission study on new genomic techniques will be delivered by 30 April 2021. In the meantime, the United States has decided to relax the rules for biotech crops.Continue reading
The idea is bold and seems to have worked fine. By using a DNA cutting enzyme to disrupt the X chromosome, researchers succeeded in distorting the sex ratio of offsprings, eventually leading to the all-male populations collapse. Andrea’s Crisanti and colleagues at the Imperial College London did it to caged Anopheles gambiae mosquitoes in their quest for a genetic strategy to beat malaria. Please see their paper in Nature Biotechnology and the Imperial College press release.Continue reading
May 7th 2020 will be remembered as a good day for CRISPR. Yesterday the first CRISPR/Cas-based test received Emergency Use Authorization from the U.S. Food and Drug Administration. The Sherlock SARS-CoV2 kit works by programming a CRISPR enzyme to detect the coronavirus genetic signature, providing results in about one hour. Quickly and cheaply indeed, as the materials for one test cost about $6.Continue reading
Say hello to CARMEN: a massively multiplexed, Cas13-based technology for nucleic acid detection, out yesterday in Nature. Its name stands for Combinatorial Arrayed Reactions for Multiplexed Evaluation of Nucleic acids, and it allows us to test many amplified samples for the presence of many viral sequences by using miniaturized detection reactions that self-organize in a microwell array. Sars-Cov2 included.Continue reading
Researchers from all the life sciences are turning their attention to the pandemic, and the CRISPR community is no exception. The latest CRISPR Journal‘s editorial presents a few of the projects that are showing promise, and others are probably going on. Kevin Davies and Rodolphe Barrangou also comment on the cancellation or postponement of several key conferences in the next few months due to Covid-19, especially the CRISPR 2020 meeting in Paris. They applaud all the scientists who are battling this disease in myriad ways and promise: we’ll meet again.
