  4. A Misonne’s spider geckos standing on sandy ground

    Here’s how spider geckos survive on Earth’s hottest landscape

    An analysis of the stomach contents of Misonne’s spider geckos shows there are more critters in the heart of Iran’s Lut Desert than meets the eye.

  5. image of the remains of a church on a hillside in Greenland

    Vikings may have fled Greenland to escape rising seas
