Makrides asked 272 nursing moms who had given birth prematurely to take six omega-3 capsules a day, to mimic the 1% ratio that full-term babies receive in their final months in the womb. A control group of 273 similar moms took six capsules of soy, a placebo. Overall, the two groups showed no differences in cognitive tests 18 months later, but when Makrides looked at the data by gender, she found that girls getting the omega-3 supplemented breast milk did slightly better than girls receiving regular milk. The smallest premature babies also showed more benefit from...
...research, to be published Jan. 13 in Proceedings of the National Academy of Sciences, a U.S. journal, scientists measured 44 male traders' second-to-fourth-digit-length ratio, which is otherwise known as 2D:4D and is an indicator of the effects of prenatal testosterone. The longer a trader's fourth finger relative to his index finger, and therefore the lower the 2D:4D ratio, the greater his prenatal exposure to the hormone. All of those taking part in the study carried out the same type of trading over the 20-month period studied and had the same access...
...Clearly, that a lower ratio pointed to higher profits speaks to a little more than finger length. Earlier studies indicated that prenatal exposure to testosterone, which spikes between the 9th and 18th weeks of gestation, increases a person's sensitivity to the effects of the hormone much later in life. The greater the exposure as a fetus, in other words, the higher the levels of confidence, vigilance or risk appetite triggered by testosterone in an adult. That observation has already made digit ratio a useful indicator of ability in fields other than finance; 2D:4D has been found to predict...
...make better traders than women? Not exactly. Though it helped determine the male subjects' returns, the 2D:4D ratio accounts for only 20% of the difference in profit levels observed in the study, according to John Coates, a Wall Street trader turned Cambridge scientist and the study's lead author. "Which means there's 80% left unexplained. It's like height in tennis. It appears to give you some sort of advantage, but there's probably a dozen other things giving you an advantage, and if you were to focus just on [height], you'd be missing all sorts...
...that translates into actual home-price declines is a little tricky. After all, the price-rent ratio is based not just on home prices but on the cost of rentals too. So to figure out what will happen to home prices, you first have to make some assumptions about what will happen in the apartment market. Property & Portfolio Research does such a forecast, which is how Economy.com parlays price-rent ratios into projected house-price appreciation. Those figures tell us that the housing market remains a lumpy place - were price-rent ratios to return to normal, San Antonio would...
