Noted geneticist Snoop Dogg once said--and I'm paraphrasing here--that no matter where one goes in life, one's surroundings during one's formative years stay with one for life. No matter where you go, you can't change where you're from (I think Prof. Dogg was actually calling back to an old Comrads lyric from the song Homeboyz--I'm sure you all will correct me in the comments). Findings published today in the International Journal of Epidemiology suggest that he may have been correct--socio-economic status and living standards early in life may actually cause changes to your DNA that you carry with you for life, regardless of how your living conditions change along the way.
Thinking of pulling off the perfect crime? Here’s one more thing you now need to take into account (thanks for nothing, science): your saliva. Yes, it’s no longer enough to keep track of every single hair, every last skin cell, and and absolutely everything you touch at the scene of your nefarious scheme. Researchers at UCLA have figured out how to determine age to within five years from nothing more than a saliva sample.
