An anonymous reader writes “My 7-year-old daughter is asking some interesting questions, such as, ‘How did everything get created?’ I’ve explained, in general terms, our family’s non-religious views on the subject of creation and the Big Bang. I’d like to find some documentary videos geared to this age level that may explain better these concepts and theories. I’ve found a few PBS specials online - Stephen Hawking stuff - but they seem to be geared for young adults and older. Does anyone have recommended titles that might be better geared to children of this age bracket?”

I Don’t Believe in Imaginary Property writes “Taser International recently started a legal campaign against medical examiners who claimed tasers contributed to the cause of death for several people. On Friday, an Ohio judge ruled in favor of the stun gun manufacturer (free registration may be required). While they do have a number of scientific studies on which they establish their claims, it’s interesting that the alternate cause of death they champion — excited delirium — appears only in police reports on the deaths of difficult or drug-addled inmates, not in medical textbooks. Of course, that may change soon — Taser is funding and promoting research on the subject. Coroner reports such as the ones in this case contributed to …

Roland Piquepaille writes “Networks are used to represent the structure of complex systems, including the Internet or social networks, but often these descriptions are biased or incomplete. Now, researchers at the Santa Fe Institute (SFI) have shown that it’s possible to extract automatically the hierarchical structure of networks. The researchers say their results ’suggest that hierarchy is a central organizing principle of complex networks, capable of offering insight into many network phenomena.’ They also think that their algorithms can be applied to almost every kind of networks, from biochemical networks (protein interaction networks, metabolic networks or genetic regulatory networks) to communities in social networks. But read more for additional references and some pictures about hierarchical networks and their applications.”…

NotBornYesterday writes “On April 8, Iranian President Mahmoud Ahmadinejad visited his country’s secretive nuclear enrichment plant at Natanz for a photo op. What came out of this visit is a series of photos which have caused a fair amount of interest among western scientists. Shown in the photos are not only some of the inner workings of the plant and current generation of enrichment centrifuges, but also key components to newer generations of more effective centrifuges. Analysts are ‘intrigued’ not only by the technical revelations in the pictures, but also because Iran’s Defense Minister Mostafa Mohammad Najjar accompanied Ahmadinejad through the facility.”
