there was correlated stuff presented on the PBS _Scientific American..._
show tonight (last night; 25Jan2000). i didn't record the segment, so i
can't provide details, but it had to do with limitations with respect to
the number of times a cell can divide.
the segment talked of extending life by defeating this mechanism.
be careful, here, because one obvious reason for having a limit on the
number of times a cell can divide is the propensity for 'weary' cells to
become increasingly susceptible to mutation.
other correlated thing: it was in the news, recently, that 'patents' have
been recently applied for with respect to the "Dolly stuff".
