Senescent cells stop producing nucleotides: new research
Now granted I only have a undergraduate degree in Chemistry, but to me, the statement "the lack of nucleotides causes cells to age" is akin to saying "the lack of steel causes a car factory to stop".  Of course if a cell lacks the basic components to divide its DNA it... won't divide?  The more interesting question is _why_ are there no nucleotides in cells that are aging.<p>My sense is that this summary of the underlying article is missing something (not uncommon in scientific journalism), or this really isn't all that revolutionary.<p>I'd love for a better explanation of why this matters, or a better link?
