Does Prenatal Testosterone Make You Smart?

Prenatal exposure of higher levels of testosterone turns out to be a relatively easy thing to measure because it manifests in a person's second to fourth digit ratio on their hands. Previous studies of digit ratio have suggest that this exposure may increase one's likelihood of being homosexual. A new study suggests that it may increase one's odds of having an IQ over 130, adding to prior work showing connections to primate social behavior, math test scores of seven year olds, and sports performance in women, to name just a few.

Scientists have also discovered a type of cell in the intestines that produces opium-like substances called tuft cells.

Also, in proof that probably dubious seeming experiments can produce good results, Japanese scientists have discovered that soaking superconductor material in Sake dramatically increases the rate at which the superconductors are produced. Further experimentation determined that superconductor materials prefer red wine to whiskey, suggesting that the alcohol itself is probably not the critical factor.
