New Science Could Sharpen Crispr's Gene-Editing Scalpel
b'Stay on target. That\\u2019s the mantra you hear in labs and biotech companies around the world as they snip away at DNA. All the techniques for gene editing\\u2014from the famous Crispr-Cas9 to the older TALENs and zinc-finger nucleases\\u2014share a problem: Sometimes they don\\u2019t work.
