...clues are tantalizing. In some research centers, investigators are studying an area at the tip of chromosomes that appears to shorten, fuselike, as we grow older. Extinguish the chemical fire that consumes the fuse, and you might be able to bring aging to a halt. Elsewhere, scientists are studying how the waste produced when a cell consumes food can contaminate its innards, a process that can lead to the body-wide breakdowns we associate with aging. Clean up the cells, and you should be able to buck up the entire organism. Still elsewhere, geneticists are beginning to map the very...
...telomeres weren't completely inert. One thing they almost always appeared to do was grow shorter. Each time a cell divided, the daughter cells it produced had a little less telomere to play with. Finally, when the cell reached its Hayflick limit of 100 or so replications, the telomere was reduced to a mere nub. At that point, the cell quit replicating. Once it did, researchers theorized, the genes previously covered by the telomere became exposed and active, producing proteins that triggered the tissue deterioration associated with aging...
Running parallel to Schellenberg's work is research being conducted at the New York State Institute for Basic Research into the more devastating Werner's-like disorder known as progeria. People suffering from progeria grow old precociously too, but at a much faster rate; they are claimed by the infirmities of age in their 20s or teens. W. Ted Brown, chairman of the Institute's Department of Human Genetics, believes that progeria, like Werner's, is triggered by a single mutated gene. That genetic miswiring, however, may stimulate activity in the countless other genes that play a role in aging...
...Unable to capture the real merit of the book--Capote's masterly accretion of detail in telling the true story of a prosperous Kansas farm family's gruesome murder--the film meanders about, touching on unoriginal themes: that men can kill with no good reason, that boys brutalized will grow up to brutalize, that the pure of heart often die in vain...
...Nickelodeon is gaining a big chunk. As the networks have watched their ratings dwindle, Nick has seen its Saturday-morning audience grow 23.5% during the past year. "The networks have gone to the same tired well too many times," argues Nickelodeon president Herb Scannell. "They don't care about kids, and kids are feeling that...
