Electromagnetic Fields at Work Show No Brain Tumor Risk

A new study finds no significant correlation between workplace exposure to radio frequency (RF) or intermediate frequency (IF) electromagnetic waves and the most common brain tumors. This is more reassuring evidence that non-ionizing EMFs are probably safe.

Pulsed Electromagnetic Field Snake Oil

Noel Edmonds is a game show host, famous for Britain’s version of Deal or No Deal. As far as I can tell, he has no medical or scientific qualifications at all. This unfortunately has not stopped him from using his celebrity status to offer dubious medical advice via his Twitter feed. Such is the world in which we live. Edmonds tweeted, referring...

“Electromagnetic hypersensitivity” and “wifi allergies”: Bogus diagnoses with tragic real world consequences

"Electromagnetic hypersensitivity" and "wifi allergies" are two names given to a nonexistent medical condition in low energy electromagnetic fields like wifi are blamed for a variety of health conditions. This is a story in which the parents' insistence that their teenage daughter, who had posted threats to commit suicide on social media, had this condition appears to have interfered with seeking mental...

Lawsuit Alleges School Wi-Fi Harmed Child with Electromagnetic Hypersensitivity

My mother had a favorite saying that rhymed: “All you need from dawn to dawn is someone else to blame it on.” WiFi involves mysterious emissions that you can’t see and that sneakily permeate our environment, and they have become a popular target for blame. A lawsuit has been filed against the Fay School in Massachusetts on behalf of a 12-year-old boy...

Reassessing whether low energy electromagnetic fields can have clinically relevant biological effects

It is with some trepidation that I write this, given that I realize this post might lead to charges that I’ve allowed myself to become so open-minded that my brains fell out, but I think the issues raised by what I’m about to discuss will make our readers think a bit—and perhaps spark some conversation. Because I’m in a bit of a...

Magnets and Blood Flow

Over the last week I have received numerous questions about a recent study (yet to be published, but highly publicized in the press) in which it is claimed that the application of a magnetic field can improve blood flow. Physics World declared in the headline that, “Magnetic fields reduce blood viscosity.” This is not a bad summary of the study, but then...
