Thank you for the references. In looking at the others who have reported this it is true they do not supply references. Just because everybody else is doing it though does that make it right? NO! Reports on "science" need to at least follow some of the premises of science and one of the lynchpins is accountability, where does the info come from specifically? Many times the willingness to do this is what distinguishes real science from pseudo or junk science and creditable reporting from sensationalistic. I must say thankyou again for supplying this information. Please consider providing this type of info as a matter of course instead of when a reader hold you to task.
