Clues to Anthrax Attacks Found
Gotta thank Mr. Shane for bursting the balloon about that recent claim of "two types" or such being new news. It's over two years old.
As far as I can tell, this article does not say that differences were found among the attack anthrax samples. It just says that there are differences among the various reference samples of Ames. This is why the attack samples can be compared to the reference samples to tell which reference sample is the closest genetically.
The new statement is that there were two slightly-different genetic types mixed in the samples of the attack anthrax. This is a very different statement.
Now, according to Shane's recent article, this was discovered quite some time ago, but I do not believe there was any public announcement of this until the recent article.
