For all intents and purposes, Brendon Rockey farms in a desert where native soils have almost zero organic matter and precipitation is infrequent. But as bleak as that may sound, Rockey’s farm is actually thriving and biologically active.
In many nitrogen-fixing bacteria, a protein called RirA plays a key role in regulating iron by sensing high levels of the metal and shutting down the production of proteins that bring in more iron.

But until now, exactly how this cluster structure detects iron levels in a cell was unclear, says the University of East Anglia.
