It does more than just ring a bell. In fact I've already pointed out the fallacy of a previous attempt to use it: Doctor Meles. Yet another researcher incorrectly cited in support of alternative AIDS theories... (Response posted 13th March 2003.)

In short, only 31 out of the 1437 tested were found to be indeterminate. Discussing the breakdown of the 31 whilst ignoring the other 1406 and ignoring the conclusions of the authors themselves is not really helping anyone.

This is the second time I have been incorrectly chastised for pointing to what has been posited (as well as posted).

To 'posit' is to put forward as fact or as a basis for argument. To posit something is to base something on the truth of (a particular assumption) - ORIGIN C17: from L. posit-, ponere 'place'.(2)

I don't think recycling misrepresentation of Meles' paper will lead anywhere. What the Perth Group need to do is explain how the Crawford(3) and Sinoussi(4) papers have failed to measure up to their claims. In attempting to validate their insistence that HIV must be separated by density gradient centrifugation, they have pointed to two experiments where the viruses involved are also not 100% purified(5).

If similar viruses fail this test, does that mean that they also cease to exist?
