Pretty damned cool article. If you read it, note that there are a couple of typos that you can parse out. It's stated at the end of the article, but worth noting that this originally appeared in Wired: Japan and is a translation.
"Experimental results showed that the critical Reynolds number at which the turbulent transition begins increased from approximately 1.9 × 10⁶ to 2.2 × 10⁶ for the DMR-coated model, and drag was dramatically reduced by up to 43.6 percent in the transition zone. Furthermore, the DMR-applied surface consistently showed a drag coefficient lower than that of the smooth surface up to the highest measured Reynolds number (3.6 x 10⁶)."
I also think it's pretty bad-ass that they came up with a way to suspend a model in the wind tunnel through electromagnetism vs. a physical structure.
