In the thirteenth round of Grand Challenges Explorations, proposals were solicited that targeted the following topics: inciting healthy behaviors, developing research tools and models for enteric dysfunction, innovations for more effective agriculture development systems, integrating community-based interventions, and new approaches for assessing early brain development.
The new topic "New Ways of Working Together: Integrating Community-Based Interventions" seeks to leverage existing mass drug administration programs as platforms for additional health interventions. The new topic "Explore New Ways to Measure Fetal and Infant Brain Development" seeks new assessment tools for early brain development and gestational age, focusing on tests that are simple, reliable, non-invasive, objective, and universally applicable.
