Bioelectric signals can be used to detect early cancer
Somerville MA (SPX) Feb 05, 2013
Biologists at Tufts University School of Arts and Sciences have discovered a bioelectric signal that can identify cells that are likely to develop into tumors. The researchers also found that they could lower the incidence of cancerous cells by manipulating the electrical charge across cells' membranes. "The news here is that we've established a bioelectric basis for the early detection of cancer," says Brook Chernet, doctoral student and the first author of a newly published research paper co-aut ... read more
