Report: Prehistoric silk found in Henan

Scientists have found evidence of silk dating back 8,500 years after testing soil samples from a Neolithic site in Henan province.

The discovery greatly advances the study of the material's history and Neolithic cultures, according to a report released on Monday by the University of Science and Technology of China.

Gong Decai, a professor with the college's scientific archaeology department, spent almost six years completing the research, which he also included in a recent article for Plos One, an international academic journal.
