...StarTAC cell phone...
...good enough for globetrotting execs like Sun Microsystems' Scott McNealy, it should be good enough for you. Weighing slightly more than 3 oz., this sleek Motorola cell phone is the year's crown prince of miniaturization, using a flip-open cover to approximate the Star Trek "communicators" that are the industry's role model. New extra: long-life batteries. It's a phone Captain Kirk would be proud of. ($1,000 to $1,500; Motorola...
...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 genes that direct...
...gerontologists, this was monumental stuff. If human tissue behaved in the body the same way it did in the dish, they felt, it meant that somewhere in the nanoviscera of each cell there was an actuarial hourglass that gave it only so much time to live and no more. If the clock could be found--and, more important, reset--both the cells and the larger corpus that gave rise to them might be made immortal. Of course, hypothesizing the existence of such a cellular timekeeper was one thing; finding it and manipulating it were something else again. In the years...
Cold and hungry, of course, is no way to go through life, but the condition has its rewards. When metabolism slows down, all its attendant processes do too, including cell division. Since, as Hayflick discovered, the number of divisions is limited, animals that go through them slowly may be able to salt a few away for later in life...
