A lot of people don't give a crap. But OpenBiome, a company based in Cambridge, Mass., does, quite literally. The group has opened a facility that collects stool samples from healthy, pre-screened individuals. It then processes those "donations" and readies them for shipment to hospitals, where they are put into the colons of people with the deadly gut infection Clostridium difficile. Since September, OpenBiome has sent more than 135 frozen, ready-to-use preparations to 13 hospitals. It is, as Science News put it, a kind of Brown Cross.
