The group has been working five years in their own time in this small laboratory with shoestring budget. White has a day job in NASA and he and others are working with this project in their free time. To best of my knowledge - and correct me if I'm wrong - NASA only gave them $50,000 and a room in Johnson Space Center 2011. They don't seem to be involved in any other way but "NASA Eagleworks Laboratories" makes it sound like official NASA organization.
Their results are consistently close to the detection threshold of their sensors. They are always flirting with the measurement error.
