Intriguing find. Off the top of my head I will suggest Graham Hancock, british researcher.
Not a mainstreem scientist due to his disproving some status quo theories and presenting an alternative view based, on evidence gathered by himself and others.
You can find him on you tube and at twitter: @Graham__Hancock. Hold your cards close (tablets). If these are a threat to mainstreem they may disappear. Not trying to frighten, but to allow you to make a choice. Due diligence is the key.
Graham may know proper alternative procedure as he's been picked on for over 20 years by not being in the club. Best wishes :)
I came here interested in Arduino, but totally intrigued by your story. following
