CRISPR

An international study led by Spanish researchers has succeeded in reconstructing the ancestors of the CRISPR-Cas system present in extinct bacteria from up to 2.6 billion years ago. The reconstructed systems work and are more flexible than the current ones. According to the authors, this could open up new avenues for gene editing. The results are published in the journal Nature Microbiology.

The Spanish Confederation of Scientific Societies (COSCE) has just published a report, submitted to the EU, which proposes and compares different possibilities for reform of the regulatory framework for genome editing techniques.
