Phys.org / A new kind of CRISPR could treat viral infection and cancer by shredding sick cells' DNA

A new kind of CRISPR that destroys cells rather than gene editing them has shown potential for killing sick cells while leaving healthy cells untouched. The technology has largely been tested in cells in a dish, but if it ...
