Immaculate Conception In a Boa Constrictor 478

crudmonkey writes "Researchers have discovered a biological shocker: female boa constrictors are capable of giving birth asexually. But the surprise doesn't end there. The study in Biology Letters found that boa babies produced through this asexual reproduction — also known as parthenogenesis — sport a chromosomal oddity that researchers thought was impossible in reptiles. While researchers admit that the female in the study may have been a genetic freak, they say the findings should press researchers to re-think reptile reproduction. Virgin birth among reptiles, especially primitive ones like boas, they argue may be far commoner than ever expected."

The Rise of Small Nuclear Plants 490

ColdWetDog writes "The Oil Drum (one of the best sites to discuss the technical details of the Macondo Blowout) is typically focused on ramifications of petroleum use, and in particular the Peak Oil theory. They run short guest articles from time to time on various aspects of energy use and policies. Today they have an interesting article on small nuclear reactors with a refreshing amount of technical detail concerning their construction, use, and fueling. The author's major thesis: 'Pick up almost any book about nuclear energy and you will find that the prevailing wisdom is that nuclear plants must be very large in order to be competitive. This assumption is widely accepted, but, if its roots are understood, it can be effectively challenged. Recently, however, a growing body of plant designers, utility companies, government agencies, and financial players are recognizing that smaller plants can take advantage of greater opportunities to apply lessons learned, take advantage of the engineering and tooling savings possible with higher numbers of units, and better meet customer needs in terms of capacity additions and financing. The resulting systems are a welcome addition to the nuclear power plant menu, which has previously been limited to one size — extra large.'"

databuff writes "Google has released a data prediction API. The service helps users leverage historical data to make predictions that can guide real-time decisions. According to Google, the API can be used for prediction tasks ranging from product recommendations to churn analysis (predicting which customers are likely to switch to another provider). The API involves three simple steps: upload the data, train the model, then generate predictions. The API is currently available on an invitation-only basis." Google also recently announced several other API additions, including Buzz, Fonts, and Storage.
