Yeah, sometimes when I'm stressed out, it makes me wish I were a kid again, too.

A team of scientists has discovered a way to transform adult cells into pluripotent stem cells—the type of stem cells that is akin to embryonic stem cells, that scientists are so interested in because they are able to develop into any type of cell that appears in the body. To trigger the change, the team, including researchers from the RIKEN Center for Developmental Biology in Japan and Harvard Medical School, stressed adult cells. Three types of stresses worked, Nature News reports: a toxin that punches holes in the cells' membranes, a dip in an acid bath, and being squeezed.
