Scientists have new insight into how pollution affects marine life thanks to the new florescent green zebrafish they created.
Chemicals in the ocean have long been wreaking havoc on the zebrafish's reproductive system.
So a team at the University of Exeter in England decided to test the fish's sensitivity to different chemicals that affect the estrogen hormone — stuff like ethinyloestradiol, used in the birth control pills and hormone replacement therapy treatments; nonylphenol, used in paints and industrial detergents; and Bisphenol A, which is found in many plastics.
They gave the fish a genetic system that amplifies the response to those chemicals, producing a fluorescent green light. Now, the researchers can see just what parts of the fish are responding to the pollutants.
