waterpro42 I got your message but can't reply. I know only as much on this stock as I've seen on the boards and from their PR's. Been here at SCIE for just about a year and waiting out the long term patents, distribution, and sales. Duke happened and they do have machines being used currently. Just for a quick history I believe there was a $3 buyout offer prior to my investment here. Others can provide more info, much better than I. LONG SCIE!
