Fight Aging!

Do you want to live a longer life in good health? Simple practices can make some difference, such as exercise or calorie restriction. But over the long haul all that really matters is progress in medicine: building new classes of therapy to repair and reverse the known root causes of aging.

(From Medical News Today). You may recall that scientists demonstrated impressive muscle growth in genetically engineered mice that lacked the growth regulator myostatin. The same team has now shown that "it's possible to get the same effect by blocking the gene for myostatin, rather than entirely knocking it out. ... Until now, it's been purely theoretical that we could block the gene and obtain the same muscle-building effect as deleting the gene." This makes therapies for age-related muscle loss and wasting diseases much more plausible in the years ahead, although "for human applications, this research is just the beginning."
