But determining which chemicals are at fault poses a serious challenge 鈥� akin to solving a hit-and-run case, decades after the fact. Two researchers in the UC Davis College of Biological Sciences are developing a method that could identify harmful chemicals far more quickly, with the help of red- and green-glowing zebrafish.</span></span></span></span></span></span></span></span></span></p> August 15, 2023 - 10:00am Andy Fell /health/news/using-glowing-fish-detect-harmful-pesticides
