AI research uncovers 300 ancient etchings in Peru's Nazca desert

Japanese scientists have used artificial intelligence to uncover 303 new etchings in Peru's Nazca desert -- doubling the amount of known geoglyphs made some 2,000 years ago by a pre-Inca civilization. The fabled Nazca lines, a series of massive incisions on the desert floor depicting animals, plants, imaginary beings and geometric figures, have fascinated scientists ever since they were first discovered around a century ago. Best viewed from the air, the lines situated some 350 kilometers south of Lima are one of Peru's top tourist attractions.
