A new study, out today, by a team headed by Hugh Taylor at Yale University has found that mice exposed to cell phone signals in the womb run the risk of altered neurological development and subsequent behavioral disorders. The paper is open access. For more on the new paper, see the write-ups from the Yale press office and IEEE Spectrum.
The Yale study lends support to the surprising finding, reported a couple of years ago that young children born to mothers who had used cell phones during pregnancy were more likely to have behavioral disorders, such as hyperactivity and emotional problems. That 2008 study was repeated by the same group in 2010 with similar results.
