University of Guelph researcher Emma Allen-Vercoe and her team have devised a method for creating artificial poop for use in fecal transplants, a promising therapy for people whose intestinal flora have been damaged by illness, antibiotics, or other therapies. The recipe involves a combination of indigestible cellulose and a starter culture of fecal bacteria. These are mixed in an airtight chamber and passed through a "robogut" -- a mechanical analog of the human digestive system that produces the finished turd.
Emma Allen-Vercoe: It contains things like the indigestible cellulose that’s left after a meal has passed through your digestive tract and down to your distal gut, the end of the line for digestion. It’s pretty nasty-looking. It’s a brown sludge, it’s got lumps of starch, and it’s kind of gloopy. It doesn’t look or smell very appetizing.
PS: How do you turn that sludge into a fecal transplant?
EAV: Robogut. Robogut is made of six big beakers full of that sludge that are warmed to body temperature. And we add the bacteria from a small amount of human feces. Since oxygen is poison to anaerobic gut bacteria, each vessel is sealed to make it airtight, while sensors monitor temperature and acidity.

Eliza writes, “A researcher from Lehigh University has invented a light-based pacemaker for fruit flies, and says a human version is ‘not impossible.’ The pacemaker relies on the new technique of ‘optogenetics,’ in which light-sensitive proteins are inserted into certain cells, allowing those cells to be activated by pulses of light. Here, the proteins were […]
