Spiegel Grove artificial reef thriving

Ten years ago on May 17, 2002, the USS Spiegel Grove landing ship was intentionally sunk in the waters off Key Largo, Florida, to serve as the foundation for the Spiegel Grove project which would create an artificial reef.

Ancient ice cave in Ningwu County

Tourists visiting a purported three million-year-old ice cave in Ningwu County, Shanxi Province, China, snap photos of the protrusions and mounds of ice that have formed in the underground sanctuary. The interior of the cave is lit by colorful LEDs to give the normally bland ice an infusion of color - LEDs are used because they run relatively 'cool' unlike incandescent or even fluorescent lights.Photo credit: Xinhua / Landov / Barcroft Media
