Vedic Mathematics : Shulba Sutras
From research paper "Applied Geometry of the Sulba Sutras" by John F. Price The Sulba Sutras, part of the Vedic literature of India,describe many geometrical properties and constructions such as the classical relationship a 2 +b 2 =c 2 between the sides of a right-angle triangle and arithmetical formulas such as calculating the square root of two accurate to five decimal places. Although this article presents some of these constructions,its main purpose is to show how to consider each of the main Sulba SDtras as a finely crafted, integrated manual for the construction of citis or ceremonial platforms. Certain key words, however, suggest that the applications go far beyond this. Paper "Square Roots in the Sulbasutra" by David W. Henderson can be read here .

Deciphering Indus Script- Professor Rajesh Rao's journey
Professor Rajesh Rao have done extensive research to decipher Indus Script. His research paper was published in IEEE with subject "Probabilistic methods for analyzing sequences are providing new insights into the 4,000-year-old undeciphered script of the Indus civilization". He also rebutted claims of Steve Farmer, Richard Sproat, and Michael Witzel that "the Indus valley civilization was illiterate and that Indus writing was a collection of political or religious symbols". His paper to debunk above thesis from Witzel can be read here . Following is his excellent talk on the research at TED.
Sarasvati Valley Civilization
The Sarasvati River (Sanskrit: सरस्वती नदी sárasvatī nadī) is one of the chief Rigvedic rivers mentioned in ancient Hindu texts. The Nadistuti hymn in the Rigveda (10.75) mentions the Sarasvati between the Yamuna in the east and the Sutlej in the west, and later Vedic texts like Tandya and Jaiminiya Brahmanas as well as the Mahabharata mention that the Sarasvati dried up in a desert. Here you can find more information on it. Article : Recent Research on the Sarasvati River by Stephen Knapp 180 Page eBook : SARASVATI RIVER by Dr. S.
