biotech One Species' Genome Discovered Inside Another's. slyyy writes "The Universtiy of Rochester has discovered the complete genome of a bacterial parasite inside the genome of the host species. This opens the possibility of exchanging DNA between unrelated species and changing our understanding of the evolutionary process. From the article: 'Before this study, geneticists knew of examples where genes from a parasite had crossed into the host, but such an event was considered a rare anomaly except in very simple organisms. Bacterial DNA is very conspicuous in its structure, so if scientists sequencing a nematode genome, for example, come across bacterial DNA, they would likely discard it, reasonably assuming that it was merely contamination--perhaps a bit of bacteria in the gut of the animal, or on its skin. But those genes may not be contamination. They may very well be in the host's own genome. This is exactly what happened with the original sequencing of the genome of the anannassae fruitfly--the huge Wolbachia insert was discarded from the final assembly, despite the fact that it is part of the fly's genome.'"[Slashdot] 10:55:32 AM    comment [] web services Survey Shows More Women Blogging Than Men. thefickler writes "The blogosphere has hit the mainstream, according to a new survey, which reveals that 80% of Americans know what a blog is, 50% regularly visit blogs, and 8% publish their own blog. The survey also reveals that more women than men are bloggers, with 20% of American women who have visited blogs having their own versus 14% of men."[Slashdot] 10:54:12 AM    comment [] econtent A Model for Open Source Science. Thanks to Peter Suber's Open Access News for this reference to a model for open source science based on open source software development. The model was developed by Karim Lakhani at the Harvard Business School. ____JH _________ Karim R. Lakhani: "Open source collaboration is a very different model for innovation and product development than most firms are used to. I began to wonder where we might see similar patterns occur outside the software domain. In open source communities we see a vast degree of openness in which everybody can participate, but also the practice of broadcasting your work to everybody else. People continually broadcast their problems, others broadcast solutions, and the person with the problem is not always the one with the solution. Oftentimes, somebody else can make sense of both what the problem has been and what people are proposing as solutions, and can come " _____ Martha Lagace, Open Source Science: A New Model for Innovation, Working Knowledge, November 20, 2006. An interview with Karim Lakhani, an assistant professor at the Harvard Business School. (Thanks to John Russell.) Excerpt: In a perfect world, scientists share problems and work together on solutions for the good of society. In the real world, however, that's usually not the case. The main obstacles: competition for publication and intellectual property protection. Is there a model for encouraging large-scale scientific problem solving? Yes, and it comes from an unexpected and unrelated corner of the universe: open source software development. That's the view of Karim R. Lakhani, an assistant professor at Harvard Business School with an extensive research background in open source software communities and their innovation and product development strategies. His latest research analyzes how open source norms of transparency, permeable access, and collaboration might work with scientists. By noemail@noemail.org (Peter Suber).

The Annenberg Foundation has provided instructional media to schools, colleges, and to public television for many years. Some of the Annenberg Media productions are now freely available online. Registration is required. The Teacher Resources are organized by discipline and age group and are searchable with key words. Some examples include "A World of Art," "The Constitution," "Human Geography," "In Search of the Novel," and "Seasons of Life." Although the materials are directed at teachers for use as supplements to classes, they will also be useful for students and adult learners.____JH _____ "Annenberg Media is a unit of The Annenberg Foundation. Our mission is to advance excellent teaching in all disciplines throughout American K-12 schools. Former names of Annenberg Media are: Annenberg/CPB, The Annenberg/CPB Project, and The Annenberg/CPB Math and Science Project. We pursue this mission by funding and broadly distributing multimedia resources for teachers to help them improve their own teaching practice and understanding of their subject. Annenberg Media makes use of telecommunications technologies—the Internet, including broadband video streaming, and satellite television broadcast—as well as hard copy media to disseminate these multimedia resources, ensuring that they reach as many teachers as possible."

Though simple in comparison to full-blown simulators, Google Earth's is fun and addictive. To get started, press Ctrl+Alt+A for the initial dialog (on OS X, Command+Option+A). Then choose your plane (F16 or SR22) and initial airport. Joysticks are supported; it has even been reported that force feedback works. The game's controls are sensitive so it takes some getting used to. Here are all the available controls. For a quick overview, check out this YouTube video."
