Future CSIs might determine time of death from genes

Genes may contain a living record of your life — or, the end of your life. In a paper published Tuesday in Nature Communications, scientists describe a number of genes that change the way they're expressed after death.

Why it matters: In the future, it's possible the patterns these scientists found could be used to precisely determine someone's time of death.
