Using glowing fish to detect harmful pesticides

Birth defects related to chromosomal abnormalities often stem from exposure to chemicals early in the mother's life. But determining which chemicals are at fault poses a serious challenge—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.
