A University of Washington computer scientist has led a statistical study of the Indus script, comparing the pattern of symbols to various linguistic scripts and nonlinguistic systems, including DNA and a computer programming language. The results, published online April 23 by the journal Science, found the Indus script's pattern is closer to that of spoken words, supporting the hypothesis that it codes for an as-yet-unknown language... In 2004 a provocative paper titled The Collapse of the Indus-Script Thesis claimed that the short inscriptions have no linguistic content and are merely brief pictograms depicting religious or political symbols.

Four-thousand years ago, an urban civilization lived and traded on what is now the border between Pakistan and India. During the past century, thousands of artifacts bearing hieroglyphics left by this prehistoric people have been discovered. Today, a team of Indian and American researchers are using mathematics and computer science to try to piece together information about the still-unknown script. The team led by a University of Washington researcher has used computers to extract patterns in ancient Indus symbols. The study, published this week in the Proceedings of the National Academy of Sciences, shows distinct patterns in the symbols'...
