What does it mean 'for the first time'? My GF in grad school ran an atomic physics experiment where they cooled helium down to a Bose-Einstein Condensate at a few billionths of a degree above absolute zero using a laser cooling system (kick out the hot ions with a laser until only ridiculously cold ones are left). Doesn't get much colder than that...
