New Scientist reporter Alex Wilkins writes that MIT researchers have developed a robotic pill that can propel itself through mucus in the intestines and could enable some injection-only medications to be taken orally. “The pill is 2.5-centimeters long and 1-centimeter wide – about the size of a large multivitamin ­– and encased in a gelatin capsule that dissolves in stomach acid,” writes Wilkins. “The pH in the lower intestine activates the motor, which is powered by a small battery.”
