Nature article by Roberta Kwok discusses the American Society for Microbiology’s Biodefense and Emerging Diseases Research Meeting in Baltimore, Maryland on February 24, 2009. Excerpt:
Joseph Michael, a materials scientist at Sandia National Laboratories in Albuquerque, New Mexico, presented analyses of three letters sent to the New York Post and to the offices of Senators Tom Daschle and Patrick Leahy. Spores from two of those show a distinct chemical signature that includes silicon, oxygen, iron, and tin; the third letter had silicon, oxygen, iron and possibly also tin, says Michael. Bacteria from Ivins’ RMR-1029 flask did not contain any of those four elements. . .
