Goblins lurk in a remote corner of Utah. They aren’t the Halloween type! Instead, they are unique, curiously shaped rocks, found by the thousands in Goblin Valley State Park.

Dogs have been human companions for thousands of years.

New data indicate that dogs most likely accompanied the first explorers as they traveled southward from Siberia and fanned out across the Americas.
Achieving water security has been a challenge throughout human history. Now, an astonishing two-thirds of the global population is projected to have difficulty accessing potable water by 2025. Energy and clean water production are correlated, and fortunately intelligent people are currently exploring options to harness the power of the sun to reduce water shortages.
