Science has taken Melanie Mayes from Tennessee to the tropics, studying some of the most important ecosystems in the world.
![ORNL scientists identified four amino acids key to signaling pathways in the PAN protein domain. Mutating any of those four resulted in disruption of the signal that tells cancer cells to multiply and spread in humans.
