Older adults with mild cognitive impairment and sleep problems who took at least 5,000 IU of vitamin D daily scored more than 13% higher on a cognitive test than those taking none.

A colossal cliff system created as the supercontinent Rodinia broke apart may have exposed the heart of the Grand Canyon nearly a billion years before the Colorado River carved it. The ancient landscape could also help explain why enormous sections of North America’s geological record appear to be missing.
