In research that could have come from the plot of a high-tech Indiana Jones reboot, airborne laser scanners have been used to reveal several undiscovered cities hidden in the jungles of Cambodia. Not only does it show how powerful this technology has become, but the findings could change our thinking on the history of south-east Asia. The newly found settlements are located close to the ancient temple city of Angkor Wat in the north-west of the country, and are estimated to be between 900 and 1,400 years old. Some of the cities look to be as large as the Cambodian capital, Phnom Penh.
