Questions Surrounding Epigenetics Study Vexes Scientists, Regulators
Only more and better data will settle a dispute about the possibility that environmental pollution can cause inheritable disease.
Scientists Say They Can't Replicate Pioneering Epigenetic Results
The murky waters of the debate over chemical exposures and health just got murkier. And a bit nastier.
Environment Becomes Heredity
Advances in the field of epigenetics show that environmental contaminants can turn genes "on" and "off" triggering serious diseases that are handed down through generations. But there's also a more heartening prospect: The same diseases may be treated by relatively simple changes in nourishment and lifestyle.
