Malnutrition causes nearly half of the deaths in children under five, a global burden of disease shouldered predominately in Africa and Southeast Asia. It can be severely disabling, and the condition is difficult to alleviate. A new study in Kenya led by Dr. Peter Rabinowitz, associate professor of environmental and occupational health sciences at the University of Washington School of Public Health, has just received a $100,000 grant to investigate whether intestine-cohabitating microorganisms, that are shared between livestock and children, might be a key to this problem. On November 20, the study received a Grand Challenge Explorations Round 11 grant from the Bill and Melinda Gates Foundation. Successful projects have the opportunity to receive future support up to $1 million.
