This is, actually, a fascinating example of the way that "science" edits it's own narrative. Reading this you'd be forgiven for forgetting that Ennis's work was investigating a certain little paper published in 1988:

Davenas, E., Beauvais, F., Amara, J., Oberbaum, M., Robinzon, B., Miadona, A., Tedeschi, A. , Pomeranz, B., Fortner, P., Belon, P., Sainte-Laudy, J., Poitevin, B. and Benveniste, J. (1988). Human basophil degranulation triggered by very dilute antiserum against IgE. Nature 333, 816-817

Benveniste's work was investigated by an ex-physicist, a psychologist and a conjurer and, on the basis of their expert opinion, consigned to the realms of pseudoscience by "Nature".

Strange how it's dropped out of the New Scientist version of events isn't it?

God is our guide! from field, from wave, From plough, from anvil, and from loom; We come, our country's rights to save, And speak a tyrant faction's doom: We raise the watch-word liberty; We will, we will,we will be free!
