CRISPR-Cas systems, defense systems in bacteria, have become a plentiful source of technologies for molecular diagnostics. Researchers at the Helmholtz Institute for RNA-based Infection Research (HIRI) in Würzburg have expanded this extensive toolbox. Their novel method, called PUMA, enables the detection of RNA with Cas12 nucleases, which naturally target DNA. PUMA promises a wide range of applications and high accuracy.
