Beetles offer people lessons in moisture control
Taking tricks from a beetle, researchers are designing surfaces that collect water from the air or resist frost buildup.
- Agriculture
The first farmers were two groups, not one
The humans that began farming 10,000 years ago in the Fertile Crescent may have been two cultures living side-by-side.
