Magnetic apprehensions: radiologists call for more testing of MRI's effects

Article Abstract:

Some radiologists believe that the newer magnetic resonance imaging (MRI) machines, which operate at four teslas rather than 1.5 teslas, may not be safe. Radio-frequency energy can increase the temperature of body tissues, and rapid gradient field switching can stimulate nerves in unusual ways.

100 years of magnetic memories

Article Abstract:

The development of magnetic recording technology started in the late 18th century, when the correlation between electricity and magnetism was established, leading to the invention of the telegraphone. Eventually, the technology was used in the storing large-volume of information.
