NOVA aired a program on Sunday 08/06/06 that was way over the line in favor of embrionic stem cells. They took a few of the main concerns voiced by conservatives, and shot them down one by one, then made outlandish claims that have so far gone unrealized.
The way they did it was to play a one sentence sound clip from the right, then present scientific evidence that refuted the offending premise. If you weren't a thinking person, this would be quite effective, but if you were thinking you'd realize they were simply setting up a one sided arguement without a scientificly based rebuttal.
As was mentioned here, there was no mention in the presentation that adult stem cells were the only stem cells that have gone beyond the promise to actually contribute to therapies to this point.
NOVA can put out some nice programming, but at times they act as disinformation specialists of the worst sort.
Here's a great forum website about stem cells

A media source using a straw man?
Say it ain't so!
