NewImage The biology behind the green glow of Japanese freshwater eels could lead to new tests for jaundice and liver problems. RIKEN research institute scientists determined that a substance found in bile, bilirubin, is what triggers a protein in the eel, called UnaG (after unagi), to glow. Turns out, the amount of bilirubin in humans is a good indicator of liver health. Using a synthetic version of UnaG, the scientists could measure the bilirubin in a blood sample based on its glow. A similar technique may also aid in the study of tumors. "An eel's glow could illuminate liver disease" (Science News)
