...Guyuron team's most interesting findings had to do with weight. Many of the twin pairs were of similar weight, but differences in how old they looked began to appear when one had a body mass index (BMI) at least four points higher than the twin sibling.

...Katherine Stothard at Newcastle University in Great Britain, the researchers reviewed 18 earlier studies of maternal weight and congenital abnormalities. Compared with women who maintained the recommended body mass index (BMI) of between 18.5 and 26, women who were obese - defined as having a BMI of 29 or greater - before pregnancy were more than twice as likely to have an infant with spina bifida, nearly twice as likely to have a baby with other neural-tube defects, and more vulnerable to giving birth to babies with heart problems, cleft palate or cleft lip, abnormal rectum or anus development, and hydrocephaly...
...have created an oversupply of chips, while the global economic slowdown is drastically weakening demand for the slivers of silicon that go into computers, mobile phones, portable music players and a host of other consumer electronics products. The result has been plummeting prices. According to a price index compiled by research firm iSuppli, DRAM prices have plunged 48% in the past six months. That is good news for consumers - cheaper DRAMs mean electronics makers can pack more memory into their gadgets - but it is a disaster for manufacturers. At current price levels, chipmakers have a hard time making money...
...Markopolos said Madoff was earning 82% of the S&P 500's return with less than 22% of the risk, but his returns only had a 6% correlation when Markopolos expected "something like a 50%" correlation. "If your returns are coming from the S&P 100 stock index, you better at least resemble that stock's performance," he said. He also compiled statistics from S&P 100 index options and from the Chicago Board Options Exchange as reported in financial media. "There were not enough index options in existence for Madoff to be managing the split strike conversion strategy...
...there is plenty of further room to fall, say economists who forecast where the housing market is headed. The median sales price of existing homes fell to $175,400 in December, down 15.3% from a year earlier, according to the National Association of Realtors (NAR). And the S&P/Case-Shiller index shows that home prices in 20 cities fell 18.2% in November compared with the year before. Both measures make houses about as expensive as they were...
