Just drop them a line and ask whether they plan to publish their research in a more formal way.

In my experience scientists respond pretty well.

Yea this is pretty annoying how hard it is to discover the sample size and methodology.

Is this even published/peer reviewed or did it just go to TV?

I'm extremely skeptical of accepting results/conclusions at face is this whole thing is around a show?
