Just a tiny alteration in its core and matter metamorphoses.
Think about it, Seeker: would you believe that particles in nature can transform?
The force that drives this transformation is the weak interaction, mediated by the W-Boson. Deep inside the atom, a quark can interact with a neutrino that travels close enough to feel the weak force. When it does, some of its properties can flip, and with them the whole atom. Incredible as it may seem, this is how we infer the age of ancient organisms: by just looking at how much carbon transformed into nitrogen.
