Nancy Talbott is the President of the BLT Research Team, Inc., a non-profit organization that for 20 years has been on the leading edge of scientific research into the crop circle phenomenon. BLT has documented multiple abnormalities found in crop circle plants and soils, including massive alteration of germination and growth-habit in seedlings grown from crop circle seeds and significant alteration of the crystallization structure of specific clay minerals in crop circle soils. Three BLT papers have been published in peer-reviewed scientific journals.
