15-year-old wins $25,000 for low-cost airborne bacteria sampler

Bailey Quinn Frank, 15, from Fort Lauderdale, Florida, won the $25,000 Thermo Fisher Scientific ASCEND Award, the top prize at the Thermo Fisher Junior Innovators Challenge. She built a low-cost environmental DNA sampler using a small fan and filter paper to collect bacteria from the air, which she says could help rural communities monitor health threats.
