...passed down to at least one successive generation. These patterns of gene expression are governed by the cellular material - the epigenome - that sits on top of the genome, just outside it (hence the prefix epi-, which means above). It is these epigenetic "marks" that tell your genes to switch on or off, to speak loudly or whisper. It is through epigenetic marks that environmental factors like diet, stress and prenatal nutrition can make an imprint on genes that is passed from one generation to the next...
Since 2004, the FDA has approved three other epigenetic drugs that are thought to work at least in part by stimulating tumor-suppressor genes that disease has silenced. The great hope for ongoing epigenetic research is that with the flick of a biochemical switch, we could tell genes that play a role in many diseases - including cancer, schizophrenia, autism, Alzheimer's, diabetes and many others - to lie dormant. We could, at long last, have a trump card to play against Darwin...
Democrats will hold 257 House seats to the GOP's 178 after Griffith's switch...

Certainly not a deal breaker in our book, but if you're a compulsive channel surfer, there's a chance it could become a nuisance...
