That's fascinating. Presumably the other problems with wood outweigh the heat transfer problem (rot? what else?).
Not in my opinion. While the above poster is correct about wood being a better insulator, there is not enough wood in the frame to make enough difference to outweigh the downsides (weight, wood is held together with staples and weakens in the joints over time, rot, mold retention, 1x1's are not as strong, etc) so you can always add heat, insulation, ect you can't fix the main structure.
I've had both and really if a person is saying they can measure the difference heat retention between 1x1 aluminum framing and wood, I'd be very leery....
