Medicine & TechnologyArchaeologists have unearthed the skeletons of two men who were buried apparently holding hands in the tunnels of London's new Crossrail
Finding of ancient tunnels is a fascinating discovery. While the subway looks like a new concept, there are many 'secret' tunnels built in the bygone era.
In a sky-high archaeological dig, based near the peaks of the Peruvian Andes mountains, an international team of researchers unearthed the oldest-known evidence of human settlement high above sea level. In fact, the rock shelters and tool fragments found, date back roughly 12,000 years and lie 14,700 feet above coastal sea level at the base of the mountain range.
