I've read the article, and you also have to realize that newspapers are notorious for misquoting scientists. I remember reading in the San Francisco Chronicle a number given in degrees fahrenheit for the temperature at "which all motion stops" was minus 260.7. First, that's closer to the Celcius temp for absolute zero. Second, it's still not correct (I think it's more like 273.15). Third, absolute zero is the temperature at which all translation motion stops (we still have zero-point vibrational motion in molecules at that temperature.)
Yes, -273.15 degrees C is the absolute point conversion for 0 K. For fahrenheit, it is -459.67 degrees F.
