    Ethyl acrylate: A substance used in making latex paints and textiles. The US government removed ethyl acrylate from its list of potential cancer-causing agents in 2000. Although ethyl acrylate induces tumors in animals, it only does so when the chemical is given by mouth at such high concentrations ...
  5. Ethylene glycol poisoning Ethylene glycol poisoning
    Ethylene glycol poisoning: Poisoning from ethylene glycol (a clear, colorless, odorless liquid with a sweet taste) that can produce dramatic and dangerous toxicity.

  15. Euphenics Euphenics
    Euphenics: Literally meaning "normal appearing," euphenics aims to improve the outcome of a genetic disease by altering the environment. An illustration: children born with the genetic disease phenylketonuria (PKU) can avoid the expression of their disease by staying on a low-phenylalanine die...
