A 14-year-old student from Georgia has won a national science competition for creating a handheld device that could help consumers detect pesticide residues on fruits and vegetables. Sirish Subash, a ninth grader from Snellville, developed PestiSCAND, an AI-powered device that was tested on spinach and tomatoes and achieved more than 85% accuracy, according to 3M. His project won the title of America’s Top Young Scientist in October 2024 and came with a $25,000 prize.
