15-year-old US student invents low-cost device to collect airborne bacteria; wins $25,000 at science competition

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 (eDNA) sampler using a small fan and filter paper to collect airborne bacteria, which she says could help rural communities monitor health threats, according to Society for Science.
