Genes that turn off after death, and debunking the sugar conspiracy

Genes that turn off after death, and debunking the sugar conspiracy

Some of our genes come alive after we die. David Grimm—online news editor for Science—talks with Sarah Crespi about which genes are active after death and what we can learn about time of death by looking at patterns of postmortem gene expression. Sarah also interviews David Merritt Johns of Columbia University about the so-called sugar conspiracy. Historical evidence suggests, despite recent media reports, it is unlikely that “big sugar” influenced U.S. nutrition policy and led to the low-fat diet fad of the ’80s and ’90s.
