All right, people—I just ran into Stranger web guru Anthony Hecht (outside the bathrooms, coincidentally), and he and I agree, based on a gut feeling (har!) and on the refrigerator in the video labeled "SHIT BURGER," that this whole Japanese-scientist-synthesizes-meat-from-human-feces thing is a hoax.
My reportorial skills falter in the face of trying to confirm a story out of Japan, but when you google "Okayama Laboratory"—where researcher Mitsuyuki Ikeda has supposedly synthesized the poop-meat—you get a website for a company that makes stents and other medical devices. And here's the only hit for Mitsuyuki Ikeda besides all the recent turd-meat "news"—for a Mitsuyuki Ikeda who's the director of the Okayama UNESCO Association, not a research scientist at all.
I'm going to go out on a limb and be the first one on the internet to call it: HOAX.
UPDATE! It's funny to see various outlets rewrite the "story." Here's the International Business Times, a.k.a. "the leading source of analysis on international business and world affairs":
Mitsuyuki Ikeda, a researcher from the Environmental Assessment Center in Okayama has developed a new a artificial meat burger but before you go drooling over it, be warned—it's made of human poop.
Somehow this feels like a Vonnegut plotline: population boom equals food shortage. Solution? Synthesize food from human waste matter. Absurd yes, but Japanese scientists have actually discovered a way to create edible steaks from human feces.
