(Oct. 6, 2007) Despite great concerns that small amounts of ingested perchlorate—a chemical which is ever-present in the environment—decreases thyroid function among individuals, it has no effect on the thyroid function of women in early pregnancy, including those with a low-iodine diet, according to a new study being presented on Saturday, Oct. 6, at the 78th Annual Meeting of the American Thyroid Association (ATA) in New York. Thyroid hormone is critical for the neurodevelopment of a fetus—particularly in the first trimester of pregnancy—and requires the mother to receive an adequate intake of iodine.
These findings are in contrast to last year's report from the Center For Disease Control and Prevention (CDC).

Scientists reported new evidence that infection with a common virus may be a contributing factor to the obesity epidemic sweeping through the United States and other countries. In laboratory experiments they showed that infection with human adenovirus-36 (Ad-36), long recognized as a cause of respiratory and eye infections in humans, transforms adult stem cells obtained from fat tissue into fat cells. Stem cells not exposed to the virus, in contrast, were unchanged.
