Solved cryptogram
Two nitrogen atoms hold each other with a triple bond, one of the strongest links in chemistry.
Chemistry Facts, sourced to Royal Society of Chemistry.
What it means
Breaking that bond is the hard part of making fertilizer, and it consumes a serious fraction of the world's industrial energy. The Haber process forces nitrogen and hydrogen together at high pressure and temperature over an iron catalyst. Roughly half the nitrogen atoms in a typical human body passed through that reaction, which is a strange thing to be true of a person.
The claim comes from Royal Society of Chemistry, and the page it comes from was read on 2026-08-27 to confirm it still says this.
This is not the kind of claim that goes out of date, which is why it was set as a puzzle rather than a fact with a shelf life.
