100 people commit their bodies to science in new study

One hundred people are about to donate their live bodies to science as part of an unprecedented new study that will examine how to improve personal health, researchers said Friday. Then, for the next 25 years, they will take regular measurements of sleep patterns, heart rate, gut bacteria, proteins that track organ health, blood samples, immune cell activity and more. "What is unique about humans is their individuality," said Leroy Hood at the American Association for the Advancement of Science annual meeting. Hood said scientists will be on the hunt for "actionable opportunities for each individual," such as how they could change their nutrition to improve their health or avoid certain drugs that might be dangerous given their genetic makeup.
