The Repacholi study from Australia indicates an increased cancer risk in mice exposed to mobile phone radiation. It was suppressed by major science journals (Science and Nature) because they feared it would cause panic among users.
"Mobile Phones and Cancer: Is the Popular Media Doing Its Job?" Misleading reporting about a study claiming to refute the results of Repacholi. In reality it was not a replication. The result actually indicated a trend in the same direction as Repacholi. The question is further if the "refuting" data are fully correct, as manipulation of data under the pressure of powerful industrial science sponsors is a real problem.
