This map is disturbing, once you understand it. It's a new attempt to visualize an old problem — the shrinking of underground water reserves, in most cases because farmers are pumping out water to irrigate their crops.
When it's hot and humid, you probably don't want to move much and aren't very hungry. The same goes for cows; but when they don't eat, farmers lose money.
Researchers at the University of Missouri think they can help avoid those losses. They've produced a new mobile app that can detect the threat of heat stress in cows using nothing more than a smartphone.
