The phosphor of life — the backbone of every DNA strand, the currency of every cell's energy (ATP). Without it, no memory, no movement, no metabolism.

Made primarily in supernovae and asymptotic giant branch stars. Rare on Earth — its scarcity may limit life itself.

Lab note · 1% of the body. ATP carries three phosphates; give one up, and the cell moves.
