Tiny CRISPR Protein from Tiny Archaea May Have Big Diagnostic Impact

If you could listen closely enough to Archaea, you might hear them busily shredding single-stranded DNA, most likely infectious material from a virus. And if you could look closely enough, you might see that the shredding tool used by the tiny organisms was a tiny Cas protein, not the big, bulky Cas9 protein so famous for its part in the CRISPR/Cas9 gene editing system, but another Cas9, a protein called Cas14.Although researchers have been on the lookout for additional Cas proteins that could b
