Doctors have found a way to put healthy people's poop into pills that can cure serious gut infections - a less yucky way to do "fecal transplants". Canadian researchers tried this on 27 patients and cured them all after strong antibiotics failed to help.

It's a gross topic but a serious problem. The germ, Clostridium difficile, or C-diff, causes nausea, cramping and diarrhea so bad it is often disabling. A very potent and pricey antibiotic can kill C-diff but also destroys good bacteria that live in the gut, leaving it more susceptible to future infections.

Recently, studies have shown that fecal transplants - giving infected people stool from a healthy donor - can restore that balance. But they're given through expensive, invasive procedures like colonoscopies or throat tubes.
