This UK startup is turning urine into fertilizer using 'pee-cycle' tech - Reuters

A UK startup is converting human urine into fertilizer.

How to photograph the invisible

The cosmic web connects all galaxies, but it's made of dark matter and gas we can't see. Astronomers just imaged it directly by reading light's fingerprints—a lesson in how science sees what cameras can't capture.
