A beetle in one of Earth's driest deserts drinks by catching fog on its own back

The Namib desert gets under 2cm of rain a year, but fog rolls in off the cold Atlantic most mornings. Certain darkling beetles tilt their bumpy shells into the wind, let fog droplets condense and merge on water-attracting bumps, then let them roll down water-repelling channels straight into their mouths — a design engineers have since copied for fog-harvesting nets in arid regions.
