Biohackers walk a blurry line between science and pseudoscience.

But, today, they fall square on the science side due to their recent decision to disinvite David Avocado Wolfe from the Biohacker Summit - the largest biohacking event in Europe. The meeting, held in Helsinki, Finland in mid-October, will have 1,000 attendees - all of whom will (thankfully) not be hearing what Wolfe has to say. This includes, among other things, that mushrooms have intelligence and consciousness, that chocolate is an octave of male sun energy and that the Earth is flat. 

In case you don't know, biohacking is the practice of people taking biology into their own hands. It's a cross between DIY Bio and citizen science. Whatever form it takes, it's driven by people taking an interest in science...
