A lost medieval city that thrived on a mist-shrouded Cambodian mountain 1,200 years ago has been discovered by archaeologists using revolutionary airborne laser technology, a report said Saturday.

The Dalai Lama waded into Australia's bitter gender war Thursday, saying his successor as the spiritual leader of the Tibetans could be a woman.
