Medical Hypotheses editor Bruce Charlton was given an ultimatum , ScienceInsider reports. The journal's publisher, Elsevier, told Charlton that it will not renew his contract unless significant editorial changes are made ― namely, that the journal implement a peer-review system, among other things. Last week, we at the Daily Scan blogged about researchers' rally for support for the radical journal. ScienceInsider reports that "Elsevier's move is the latest in an eight-month battle over the journal," and that Charlton says he will not revamp the journal's editorial policies, nor will he resign.
