Scientists Don't Fear a New Crispr Snag

It can feel shocking when someone disparages a golden person, thing or technology -- and in recent years, no emerging technology has glittered as brightly as the gene-altering technique known as Crispr. So some investors were apparently jolted earlier this month when MIT Technology Review ran a news item headlined “Uh-Oh -- Crispr Might Not Work in People.”

Any technology that’s never been tested in clinical trials runs that risk. With Crispr, there has yet to be a single human experiment in the U.S. or Europe. Human experiments are just beginning in China, but American researchers say they don’t have complete information on how those are turning out.
