Scientists at the University of East Anglia (U.K.) have uncovered a hidden link between gut health and the immune system—all thanks to a tiny island bird. Researchers studied the Seychelles warbler, a small songbird found on Cousin Island in the Seychelles. They collected the birds' poo to analyze their gut bacteria—and found that their immune genes influence which gut microbes thrive.
