Essentially all cells in an organism's body have the same genetic blueprint, or genome, but the set of genes that are actively expressed at any given time in a cell determines what type of cell it ...

Gene expression is inherently variable, driven by random events at molecular scales that lead to fluctuations in RNA and protein abundances among genetically identical cells. Stochastic modelling ...

What do your genes have to do with growing old? Quite a lot. But is it due to the actual DNA, or the way those genes are expressed? KPBS sci-tech reporter Thomas Fudge has more on new research that ...
