Study finds 60 new genes controlled by DNA snippet

...ssels, suggesting they may be involved in diseases affecting those tissues as well. In the larger picture, regulatory sequences may help to explain why humans have just 25,000 genes when, given the degree of human complexity, researchers had expected to find more than 100,000. Regulatory sequences may be pa...

For the first time: Longevity modulated without disrupting life-sustaining function
