AUGUST, 2016: FACEBOOK REMOVES NANCY'S FB PAGE AFTER 2 IMPORTANT POSTS On August 13th Nancy posted details about Robbert v/d Broeke's Aug. 10th video showing a light-ball creating a new crop circle. Hours later she posted the info that Mr. Laurance Rockefeller had sent copies of both BLT's "XRD Study of Clay Minerals in a cc" AND a report he had asked her to write on the v/d Broeke case to Dr. John Gibbons (at the State Dept.). Within hours FB closed her FB pg, with no warning or explanation. Details>>>

In 2009 a UK production company was hired by National Geographic TV to produce yet another biased crop circle "documentary." Most serious crop circle researchers refused to take part. Read here why, and see Bert Janssen's photos -- which clearly document National Geographic TV deliberately misrepresenting the crop circle phenomenon. (Article)

"The Physics of Crop Formations," written by John Burke (MUFON Journal, October 1998, pp. 3-7), presents a detailed explanation of the rationale behind W. C. Levengood's hypothesis that crop circles may be the result of highly energetic, thermodynamically-unstable atmospheric plasma energy systems impacting the earth's surface. (Article)

John Burke (the "B" in BLT) and Kaj Halberg present scientific evidence that the engineers who built many of the massive monuments of the ancient world may have known a secret. The henges, pyramids, mounds & dolmen were overwhelmingly sited where local geology magnified naturally-occurring EM fluctuations - energies which were enhanced by the structures built there. Addtionally, they show that seeds placed at these sites subsequently demonstrate increased growth-rate and yield, a discovery that may explain why these mysterious stone structures appeared all over the world.

"Origin of Crop Circles Baffles Scientists," written by well- known investigative reporter Leslie Kean, was published on September 16, 2002 in Rhode Island's The Providence Journal , and was the first comprehensive article published in the U.S. covering the BLT Research Team's work. (Article)

In the fall of 2002 the Discovery Channel aired "Crop Circles: Mystery in the Fields," a show in which M.I.T. undergraduates are presented as having successfully replicated multiple plant & soil anomalies known to occur in genuine crop circles. Read what really happened…. (Article)

"Beyond the Mystery," a supposedly unbiased report on the crop circle phenomenon presented on National Geographic TV in 2005, is discussed by Nancy Talbott, who was interviewed for the show. Ms. Talbott questions National Geographic TV's motives and ethics in presenting the material included--and excluded--from this show. (Article)

Other articles written by Nancy Talbott or John Burke for farm journals and the "anomalous phenomena" audience have been published in specialty publications. Newspapers in the U.S., Canada and Europe have presented some of the laboratory results obtained by the BLT Research Team, but most frequently in inadequate detail. A major article did appear in The London Times Sunday Magazine several years ago, which featured the results presented in 2004 in BLT's x-ray diffraction study of clay minerals in crop circle soils.
