Submission + - US asks scientists to censor reports to prevent te (nytimes.com) 1

Meshach writes: The United States is asking scientific journals publishing details about biomedical research to censor articles out of feat that terrorists could acquire the information. The panel cannot force the journals to censor their articles, but the editor of Science, Bruce Alberts, said the journal was taking the recommendations seriously and would most likely withhold some information. Are we heading for another rorschach-style cheat sheet being developed?
Education

Goodbye Textbooks, Hello iPad 396

PolygamousRanchKid writes "Students and teachers in grade school through higher education are using the iPad to augment their lessons or to replace textbooks. Jennifer Kohn's third grade class at Millstone Elementary School in Millstone, New Jersey, mastered the iPad with minimal training. For the most part, the students didn't need to be taught how to use their apps, Kohn says. College students are also turning to the iPad to do what they do instinctively well: saving themselves money. Marianne Petit, a New York University staff member, recently began taking credits in pursuit of another certification, and uses her iPad in place of textbooks. 'The price of the iPad pays for itself after a single semester,' Petit said. 'iPad books cost so much less it's a legal alternative for students who are using BitTorent [to pirate books].' Like the PC before it, Kohn noted that the iPad isn't a panacea for educators: It has its appropriate time and place. 'I don't use them with every lesson or even day. It's not always appropriate to lesson or objective of what I'm trying to teach,' Kohn noted."

Submission + - Software to Rate How Drastically Photos Are Retouc (nytimes.com) 1

OnionFighter writes: From the Article:
"Dr. Farid and Eric Kee, a Ph.D. student in computer science at Dartmouth, are proposing a software tool for measuring how much fashion and beauty photos have been altered, a 1-to-5 scale that distinguishes the infinitesimal from the fantastic. Their research is being published this week in a scholarly journal, The Proceedings of the National Academy of Sciences."

Deep cycle batteries are a type of lead-acid battery. The Leaf uses lithium-ion batteries, which behave very differently. Still, lithium-ion batteries should never be fully discharged, which may be a risk with his modifications.

Any program that measures charge is making a educated guess based on the past behavior of the battery. One of the people interviewed for the article states: “Until you can find out how much is really left in the batteries toward the end of its range, it’s just a guess-o-meter.” Any indicator of charge is making a guess. Perhaps his program is better at guessing, or maybe he just leaves less room for battery health, but any program that works to tell lithium-ion battery charge will have to take into account the discharge profile of that battery (which is non-linear when measured by voltage).

Submission + - Self-publishing a contraversial e-book (amazon.com)

Evildonald writes: My father is publishing a book that is too hot to publish in his home country. He will be exempt from prosecution as long as the book is not published or is directly for sale in the state that it is discussing.

We will be initially publishing on Amazon and Barnes and Noble e-book, but I am concerned that they might bow to legal pressure (whether it has jurisdiction or not) and stop sale of his book.

To protect ourselves, and to have a fallback, what other services are there out there for selling your own e-book? Are there e-publishers that are militantly resistant to legal takedowns? Is there an open-source project that has been made to self-publish reliably?

Please help my dad.

Submission + - Portable Microscope Uses Holograms Instead of Lens (gizmag.com)

Zothecula writes: While financial contributions are certainly a great help to health care practitioners in developing nations, one of the things that they really need is rugged, portable, low-cost medical equipment that is compatible with an often-limited local infrastructure. Several such devices are currently under development, such as a battery-powered surgical lamp, a salad-spinner-based centrifuge, and a baby-warmer that utilizes wax. UCLA is now working on another appropriate technology in the form of a small, inexpensive microscope that uses holograms instead of lenses to image what can't be seen by the human eye.

Comment think zombies, not ideas (Score 3, Informative) 283

The problem is that this article badly summarizes the results of computer modeling that is supposed to represent human interactions. Apparently the tipping point for their simulation is 10%. Without seeing the actual original research findings, it is difficult to see if this actually matters, but the available article seems to say that the 10% is irrespective of network structure.

The computer simulation seems more analogous to a disease outbreak than to an idea. Imagine a percentage of people are zombies. They can only attack their friends, who can fight them so long as they have more living than dead friends nearby (I am assuming here that it is 51% that is needed to change status, but who knows what the actual research used). If they don't, then they switch sides and spread the outbreak. So the simulation might be saying that if 10% of people are initially zombies, then mankind is generally doomed. If it is less, then the outbreak will be contained.

I also find it interesting that the study was funded by the military.
