New RNA molecules may play a role in aging

The genome is the master plan for all body parts, from toe nails to eyebrows. But it's not just the blueprint that determines what's built. All of the cellular players that draw instructions from the blueprint add their own interpretation to the design, and researchers are still discovering new players. Using new tools they developed, Thomas Jefferson University researchers have found a sea of a new subtype of RNA molecules in the cell, and evidence suggesting they may play a role in aging processes.
