Despite thousands of years of coexistence, exploitation and cheese, humanity seems to have missed an intriguing fact about cows: they like to point north. Or possibly south. After some exploration, it was found that other animals, such as deer, do this too.
Researchers have explored the matter and found that the ruminants are aligning themselves to magnetic north, not true north. In other words, this is about the magnetic field, not maximizing heat from the sun or getting out of the wind.

Bowing to pressure from consumer advocates, Pennsylvania officials have dropped plans to bar farmers from revealing whether or not milk hails from hormone-enhanced cows. The state's agriculture department on Thursday issued new guidelines that allow dairies to label milk so that customers know if it was produced from cows pumped with recombinant bovine growth hormone (rBGH) also known as recombinant bovine somatotropin (rBST)
