Paper in Nature about differences in gene expression correlated with chronological age.
tl;dr -- "We identified 1,497 genes that are differentially expressed with chronological age."
Quickdraw conclusion: this will require A LOT of silver bullets.
I don't think we learn a lot through the number. It might be that multiple genes are regulated by the same mechanism and turning that mechanism down brings us forward.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
