Engineers at MIT say they developed a new technology that can control neural circuits connecting the gut and the brain. Using fibers embedded with sensors, plus light sources for optogenetic stimulation, the researchers demonstrated this control in mice. The study showed that they could induce feelings of fullness or reward-seeking behavior by manipulating cells of…

Engineers at MIT and Caltech have developed an ingestible sensor that could more easily diagnose gastrointestinal motility disorders. This advance could help with the diagnosis of constipation, gastroesophageal reflux disease and gastroparesis. The engineers designed their tiny sensor to detect a magnetic field produced by an electromagnetic coil located outside of the patient’s body. The…
