...Franklin's sacred cocktail hour with a sheaf of policy papers. When, in the last months of her husband's life, Eleanor still pursued her own agenda for good government--berating F.D.R. for the appointment of two Assistant Secretaries of State whom she considered reactionaries--his aides tried to limit contact between the sick, weary President and his wife. Of course she had her reasons for disengaging emotionally from the marriage--primarily the discovery in 1918 of Franklin's affair with her social secretary. Today we would call the Roosevelts a dysfunctional couple. Yet they constructed rich and varied lives...

Eight years ago, scientists discovered that the tips of chromosomes in tissue cells shorten each time the cells replicate--until a point is reached where the cells stop dividing altogether. That point, called the Hayflick limit, comes after about 50 replications, and may be at the heart of the process we call aging...
...enzyme that lengthens the tips, known as telomeres. Last January they succeeded: Andrea Bodnar and colleagues from the Geron Corp. in Menlo Park, Calif., activated the enzyme telomerase, extended the telomeres and lengthened the life-span of cells in culture by at least 20 divisions past the Hayflick limit. In November, Geron scored another first by reconstituting the telomeres of embryonic stem cells, which are renowned for their ability to turn into any type of cell, making it theoretically possible to rejuvenate parts of any organ with a simple injection...
