The more we learn about them the more successful and productive they seem.

Thousand-year-old 'lost' pyramid city uncovered in the heart of Mexico using lasers had as many buildings as modern Manhattan

Remains of ancient 'pyramid city' as densely built up as Manhattan have been discovered in the heart of Mexico, thanks to pioneering imaging techniques.

Experts used lasers to send beams of light from an aircraft to the ground below, measuring the reflected pulses to build up a map of the region.

They discovered a lost pyramid city known as Angamuco built by the Purépecha, rivals to the Aztecs, around 1,000 years ago.
