Cell Phone Use in Pregnancy May Cause Behavioral Disorders in Offspring

Pregnant MouseVia ScienceDaily:

Exposure to radiation from cell phones during pregnancy affects the brain development of offspring, potentially leading to hyperactivity, Yale School of Medicine researchers have determined. The results, based on studies in mice, are published in the March 15 issue of Scientific Reports, a Nature publication.

“This is the first experimental evidence that fetal exposure to radiofrequency radiation from cellular telephones does in fact affect adult behavior,” said senior author Dr. Hugh S. Taylor, professor and chief of the Division of Reproductive Endocrinology and Infertility in the Department of Obstetrics, Gynecology & Reproductive Sciences.

Taylor and co-authors exposed pregnant mice to radiation from a muted and silenced cell phone positioned above the cage and placed on an active phone call for the duration of the trial. A control group of mice was kept under the same conditions but with the phone deactivated. The team measured the brain electrical activity of adult mice that were exposed to radiation as fetuses, and conducted a battery of psychological and behavioral tests.

Scientists Create Mice From Two Genetic Fathers

Via The Wall Street Journal:

Scientists have created mice that are the genetic product of two fathers, the latest in a series of unusual experiments in mammalian reproduction.

Researchers at University of Texas MD. Anderson Cancer Center and elsewhere first engineered a female mouse whose eggs contained the DNA from a male. When the female was mated with another male, the offspring had genetic contributions entirely from two males. The study appears online in the peer-reviewed journal Biology of Reproduction.

While the achievement is technically intriguing, its practical benefits are far from clear. Any move to try the same experiment in people is certain to be more complicated and controversial.

The study describes the technique as “a new form of mammalian reproduction: that could potentially be used to improve livestock breeds or preserve endangered species. more provocatively, the authors argue that if certain technical hurdles can be overcome, “then some day two men could produce their own genetic sons and daughters.” But those technical hurdles are extremely high.
