THis is a story about the supposed anthrax scare over the last two days. Turns out it's a false alarm. I can imagine how this happened. They had a positive control, they mixed it up with the sample. For something that critical, inexcusable; especially since they made the big scare without confirming the result (OTOH confirming the result might have lead to a bigger contamination problem). It's important to get this stuff right the first time.
