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.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.I'd love for a better explanation of why this matters, or a better link?
