Stem cells are responsible for our bodies developing into all of the different tissues we have today. Typically, they move in one direction - towards differentiation. However, recent research has uncovered that not only can differentiated cells revert back to stem cells in order to perform repairs, but they are found in an unlikely place: nerve cells of teeth. This could provide a source of stem cells to be used for research or the development of therapies without the need for embryonic sources.

Researchers studying 100 pairs of twins have identified a gene mutation that may confer a unique advantage for the carrier: the coveted ability to function normally on less than six hours of sleep a night. The genetic variant also appears to provide resistance to the neurobehavioral effects of sleep deprivation, according to new findings published in the journal Sleep this week.
