People who suffer from a rare genetic disorder called Williams Syndrome have a complete lack of social fear. They experience no anxiety or concerns about meeting new people or being put into any social situation, and a new study by Andreia Santos suggests that they also don't have any racial bias. From the article: "Typically, children start overtly gravitating towards their own ethnic groups from the tender age of three. Groups of people from all over the globe and all sorts of cultures show these biases. Even autistic children, who can have severe difficulties with social relationships, show signs of racial stereotypes. But Santos says that the Williams syndrome kids are the first group of humans devoid of such racial bias, although, as we’ll see, not everyone agrees. |

As reported on news.com.au, scientists from the International Cancer Genome Consortium of 12 institutes around the world will today release the first DNA profiles of some of the most prevalent types of tumors. While the story asserts that 'A new era of cancer treatment has dawned,' I'm a bit more skeptical, given that gene therapy and immunotherapy are still very much in their infancy at the current time. |

A dozen years ago, Microsoft convinced major manufacturers to put Windows CE inside devices that looked like undersized touchscreen personal computers. The platform was code-named 'Jupiter' and shipped as Handheld PC Pro, and it flopped — it turned out that people wanted full-strength notebooks. But in retrospect, it was a clear antecedent of what Apple is doing — much more successfully — with the iPad. |

Predictions are critical to modern life. Police predict where and when crimes are most likely to take place, banks predict which loan applicants are most likely to default, and hotels forecast seasonal demand to set room rates. A new project called Kaggle facilitates better predictions by providing a platform for forecasting competitions. The platform allows organizations to post their data and have it scrutinized by the world's best statisticians. It will offer a robust rating system, so it's easy to identify those with a proven track record. Organizations can choose either to follow the experts, or to follow the consensus of the crowd — which, according to New Yorker columnist James Surowiecki, is likely to be more accurate than the vast majority of individual predictions. The power of a pool of predictions was demonstrated by the Netflix Prize, a $1m data-prediction competition, which was won by a team of teams that combined 700 models. Kaggle's first competition is underway, and it is accessing the 'wisdom of crowds' to predict the winner of this May's Eurovision Song Contest. |
