May be something to it, however I have to consider the source. UCSF has never been known for it's unbiased research and opinions in the past. And this technology has only been in place for a very short time and yet they have had time to do a through study of it's effects? Sorry, I don't buy it. They have a track record of findings that support their opinions not actual results.
