Elsevier is pushing the only one of its journals that doesn't use peer review -- Medical Hypotheses  -- to start using peer review, Times Higher Education reported. The journal has to date published articles that its editor -- Bruce Charlton, professor of theoretical medicine at the University of Buckingham -- believes are "radical, interesting and well argued," Times Higher said. Elsevier started the push to change the publishing process after a controversy over the journal's publication of an article arguing that HIV does not cause AIDS. Charlton is opposing the proposed changes. "Medical Hypotheses has for 34 years been editorially reviewed and radical," he said. "Therefore [the proposals] cannot possibly be acceptable."
