Couple work to unearth secrets of lost Mayan civilization
CBSN
An American couple is using advanced technology to unearth an ancient civilization that might hold the key to building the cities of the future.
Diane and Arlen Chase share a lifetime commitment to exploring. In 1985, the pair came to the ruins of Caracol, an ancient Mayan city in Belize that was first discovered in 1937, and that includes the country's highest structure.
Diane Chase said when they first arrived, there was "no architecture visible," and it all looked like simple hillside. Since then, they have excavated over 400 buildings and uncovered hundreds of thousands of artifacts. At first, they relied on traditional archeological methods, but that all changed in 2009, when they were able to try a revolutionary technology called LiDAR, an airborne laser mapping system that can see through trees and reveal hidden spots that might otherwise have taken decades to discover.

Iwao Hakamada, world's longest-serving death row inmate and former boxer, to get new trial at age 87
Tokyo's high court on Monday ordered a retrial for an 87-year-old former professional boxer who has been on death row for more than five decades after a murder conviction that his lawyers said was based on a forced confession and fabricated evidence.

Seoul, South Korea — The South Korean and U.S. militaries launched their biggest joint military exercises in years Monday, as North Korea said it tested submarine-launched cruise missiles in an apparent protest of the drills it views as an invasion rehearsal. North Korea's launches Sunday signal the country likely will conduct provocative weapons testing activities during the U.S.-South Korean drills that are to run for 11 days. Last week, North Korean leader Kim Jong Un ordered his troops to be ready to repel its rivals' "frantic war preparation moves."

In what is now southern Italy, Pompeii was a bustling metropolis, until an eruption from the mighty volcano Vesuvius engulfed it in ash nearly 2,000 years ago. The stone skeleton of this ancient city has emerged through centuries of excavations – an intriguing glimpse of another time. Yet, at least one-third of the Roman city remains buried, and that means the tantalizing discoveries continue.
