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.

To demonstrate the Magnus effect, YouTuber PeterSripol grabbed a couple of KFC buckets and tricked out an RC plane. The resulting trial and error is mostly the latter.
One of the weirdest places in Antarctica is Blood Falls, a five-story cascade of blood-red liquid pouring from Taylor Glacier. Researchers finally traced its source: a saltwater lake millions of years old trapped under the glacier.
Fetal lambs survived for weeks in an experimental artificial womb, and scientists hope that the breakthrough could lead to new treatments for premature babies and perhaps the dreamed-of machine utopia where humans are kept mindlessly writhing in translucent plastic sheaths filled with psuedoamniotic liquid. Physicians at the Children’s Hospital of Philadelphia placed fetal lambs into […]
Bamboo has lots of uses beyond just being panda food. Things like bikes, roads, scaffolding, and musical instruments are made from the fast-growing grass. But unless you are participating in a tropical-themed LARP, you probably wouldn’t want a shirt made from bamboo stalks. So why do bamboo bed sheets make any sense? Because yarn extracted from […]
If you want to work in tech, but don’t have any desire to code web apps to help businesses sell things to other business, you might want to consider a career in cybersecurity. Judging from the apparent complete infiltration of Russian hackers in American cyberspace, it seems fair to speculate that there’s a major shortage of […]
All moms are different. But all moms like getting flowers on Mother’s Day, and that’s a fact (not, however a fact we can document in any fashion.) Instead of getting chewed out for forgetting to call her on the second Sunday of May, you can take care of it ahead of time with Teleflora’s flower […]
