On today's show, we're going to go to both places: outer space and the stuff collecting on your bureau. And, again, you may find some surprising intersections, Some of the dust on your bureau came here from outer space.
Lastly—actually firstly—we'll be talking about dust mites, the living, breathing, pooping engines of the dust ecology.
