There was a diavlog (science saturday?) that contained a discussion regarding desert varnish and a NASA person who was researching/publishing on it. For the life of me, I cannot find this session. I cannot remember who the diavloggers were either, but I want to say Horgan and Johnson. Does anyone remember this and if so, can you direct me to that diavlog? Any help would be greatly appreciated!
