From Ralph M. Science News, Vol 152., Nov. 29, '97, page 342: [first two paragraphs, the entire article is about two columns] "The low-level electromagnetic fields present in some North American homes today can diminish or wipe out a widely prescribed drug's action, at least in test tubes. Researchers have found that when exposed to such fields, the drug tamoxifen lost its ability to halt the proliferation of cancer cells grown in the laboratory. Tamoxifen is a synthetic hormone used to prevent the recurrence of breast cancer. "These findings, reported last week at a Washington, D.C., meeting sponsored by the U.S. Public Health Service, also heightened concern that these electromagnetic fields may be triggering hitherto unrecognized biological changes in people." r
