Older patients with a diagnosis of chronic sinusitis -- a disease of the nasal cavity and paranasal sinuses that often persists over many years -- have a unique inflammatory signature that may render them less responsive to steroid treatment, according to a new study.

The finding comes from NASA’s Cassini Spacecraft, which collected the data in 22 separate dives close to Saturn’s rings, before using its remaining fuel to deliberately plunge into the planet. The discovery is the best answer to a longstanding question in solar system science.
