RNA interference (RNAi) has steadily advanced the promise of using gene silencing to block the spread of viruses or even cancer. Now the technique has proven effective in humans for the first time as a nasal spray which shuts down a common respiratory virus, New Scientist reports.
MIT scientists say they've found a new way to silence disease-causing genes in specific tissues using RNA interference

For years scientists have been touting a disease-fighting technique called RNA interference. The idea behind it is pretty simple: By piggybacking on the body's own system for silencing genes, researchers think they could stop troublesome proteins from being produced, and, as a result, halt the damage those proteins cause. The trick, though, is that scientists have had a hard time figuring out how to make RNAi, as it's known, work on specific tissues.
