In brief, it's a 13-inch slate with a 1, 366 x 768 display and your choice of Core i3 or i5 processor (these are Intel's Y-series Ivy Bridge chips we're talking about).
The ceiling is lined with bamboo slats and supported on a series of enormous Y-shaped steel trusses running down the center which are painted in the colors of the spectrum.
The ongoing study is like the science-y version of the "7-Up" documentary series -- with researchers checking in on the lives of the subjects at several-year intervals.
