Researchers tested multiple commercial TENS (Transcutaneous Electrical Nerve Stimulation) devices to measure their actual electrical output characteristics. They found significant variations in pulse waveforms and discovered that device control settings often don't match the actual electrical output delivered. This technical analysis helps clinicians and users understand what these medical devices actually produce versus what their dials indicate.

Researchers exposed pregnant rats to low-level microwave radiation and found changes in their blood's iron-binding capacity, specifically affecting transferrin protein levels. This study confirmed earlier Soviet research showing that microwave exposure can alter protein composition in blood and organs at power densities that don't cause heating. The findings suggest microwave radiation may affect how the body transports essential nutrients during pregnancy.
