The MicroMundo Project in Spain and Portugal is taking an innovative approach to addressing the global antimicrobial resistance (AMR) crisis through education and hands-on discovery. Adapted from Tiny Earth, the global antibiotic discovery initiative launched at the Wisconsin Institute for Discovery (WID), MicroMundo has become one of the most extensive international branches of the network. What makes this program unique is its community-centered model. University students partner with local secondary schools, serving as peer mentors who guide younger students through real scientific inquiry: collecting soil samples, culturing bacteria, and testing for antibiotic activity. Along the way, participants gain confidence in research while contributing to the worldwide fight against AMR. As Jo Handelsman’s vision for Tiny Earth continues to grow across hundreds of institutions worldwide, MicroMundo stands out as a vibrant example of how science education and discovery can work hand in hand to inspire the next generation.
