A new article in BBC Magazine tells the story of some children in the Dominican Republic with this condition, who are known in the country as Guevedoces, which roughly translates to "penis at 12." One child named Johnny was raised as a girl, but when he matured and neared puberty, he grew a penis and his testicles descended, according to the BBC. Because DHT is responsible for the development of male sex organs, the lack of DHT means the male organs don't develop properly, according to the National Institutes of Health.

These researchers contend that the general public may not understand the FDA's usage of these words. "Unless patients understand the FDA's usage of 'breakthrough,' they may have unwarranted confidence in the evidence supporting drug claims," researchers wrote in the Sept. 21 issue of the journal JAMA Internal Medicine.

Venter's company, Human Longevity Inc, will provide the tests at a cost of $250 each through a special incentive program offered by Discovery Ltd, an insurer with clients in South Africa and the United Kingdom. Venter, the U.S. scientist who raced the U.S. government to map the human genome 15 years ago for a cost of $100,000, said the $250 price point per whole exome marks a new low in the price of gene sequencing.

"One of the first things to appreciate is that the anti-immigrant reactions are really natural, and in some ways fundamental to who we are," said Steven Neuberg, a psychologist at Arizona State University who researches prejudice and in-group/out-group relations. Evolutionarily, the brain is primed for specific threats that would have loomed over our earliest relatives, such as dangers to physical safety, infectious disease and threats to resources, Neuberg told Live Science.

Junípero Serra, a Franciscan priest who founded the first missions in the state of California, on Sept. 23. Several American Indian tribes oppose the canonization, saying that Serra was responsible for the enslavement and death of tens of thousands of indigenous tribespeople and the destruction of their culture. Some tribes are circulating petitions to protest the canonization. Read More »Shades of 'Star Trek'?

Researchers found that the women in the study who had high levels of sugar in the urine during pregnancy were about four times more likely to die from heart disease over the 50-year study, compared with the women who did not have high levels of sugar in their urine when they were pregnant. The investigators also found that the women who experienced a decline in their levels of hemoglobin during pregnancy were about twice as likely to die from heart disease later in life, compared with the pregnant women who did not experience the decline.

The finding may provide comfort for countless heart attack survivors. Many are unsure whether the vigorous activity of sex can trigger another heart attack, and there is limited and some contradictory data on the issue, the researchers said.
