What is the deal with magnetic fields?

A recently published paper exploring the connection between occupational risk factors and MND has sparked lots of interest, especially by the media. The study in question, led by Dr Roel Vermeulen from Utrecht University, The Netherlands, reviewed and studied five occupational exposures that had previously been suggested to be associated with developing MND (specifically, amyotrophic lateral sclerosis; ALS). These factors included exposure to electromagnetic fields, electrical shocks, solvents, metals and pesticides. While a few studies investigating these factors were already conducted in the past, their results are not consistent.

Despite the vast coverage of this topic in tabloids, we wanted to describe the research paper itself – to explain what exactly the researchers did, what they found and what it all means. Continue reading
