I had 3-4 posts regarding that Nature article not show up, with the excuse that they were off topic. The anonymous post above was just as off topic as mine, but obviously less important to cover up. By now, I really donīt expect an answer to the Nature article at all (although I cannot believe the level of cowardice of these people in ignoring it), but I will continue to question them on it. The TSA does many ridiculous things, but completely ignoring criticism from the major scientific publication in the World is of a magnitude that cannot left to be.
