Two New Leads to Longevity

New Scientist had two bits of good news this month for people concerned with aging. First, it reported two groups of researchers showed that it might be possible to reverse cellular aging by preventing the loss of telomeres.  Next came news of a breakthrough in understanding what may be a "master control gene" that plays a pivotal role in aging too, by acting (or not) to suppress the expression of proteins in the wrong tissues. This latter finding in yeast might well lead to a "universal aging mechanism" said the scientists. Link to full article and the full image of the Sir1 protein.
