penguinrecorder writes "The Thunder Generator uses a mixture of liquefied petroleum, cooking gas, and air to create explosions, which in turn generate shock waves capable of stunning people from 30 to 100 meters away. At that range, the weapon is relatively harmless, making people run in panic when they feel the sonic blast hitting their bodies. However, at less than ten meters, the Thunder Generator is capable of causing permanent damage or killing people."

eldavojohn writes "Metrics can get really strange — especially on the scale of national consumption. Information consumption is one such area that has a lot of strange metrics to offer. A new report from the University of California, San Diego entitled 'How Much Information?' reveals that in 2008 your average American consumed 34 gigabytes per day. These values are entirely estimates of the flows of data delivered to consumers as bytes, words and hours of consumer information. From the executive summary: 'In 2008, Americans consumed information for about 1.3 trillion hours, an average of almost 12 hours per day. Consumption totaled 3.6 zettabytes and 10,845 trillion words, corresponding to 100,500 words and 34 gigabytes for an average person on an average day. A zettabyte is 10 to the 21st power bytes, a million million gigabytes. These estimates are from an analysis of more than 20 different sources of information, from very old (newspapers and books) to very new (portable computer games, satellite radio, and Internet video). Information at work is not included.' Has the flow and importance of information really become this prolific in our daily lives?"

vintagepc writes "TorrentFreak reports that a redesign of the popular BitTorrent client uTorrent allows clients to detect network congestion and automatically adjust the transfer rates, eliminating the interference with other Internet-enabled applications' traffic. In theory, the protocol senses congestion based on the time it takes for a packet to reach its destination, and by intelligent adjustments, should reduce network traffic without causing a major impact on download speeds and times. As said by Simon Morris (from TFA), 'The throttling that matters most is actually not so much the download but rather the upload – as bandwidth is normally much lower UP than DOWN, the up-link will almost always get congested before the down-link does.' Furthermore, the revision is designed to eliminate the need for ISPs to deal with problems caused by excessive BitTorrent traffic on their networks, thereby saving them money and support costs. Apparently, the v2.0b client using this protocol is already being used widely, and no major problems have been reported."

An article at Gamasutra explores the decisions by Microsoft and Sony to launch significant hardware additions — their respective, upcoming motion-control schemes — in the middle of a console cycle, rather than waiting until the next generations of their systems are ready. It's indicative of a change to the established pattern of console wars; nowadays, it's more about adding features and gadgets to improve existing products than developing entirely new ones. Quoting: "... for Sony and Microsoft, motion controllers are their next-gen consoles. And it's a damn sight easier than launching Xbox 720 or PS4. They can debut these peripherals without needing to engineer completely new boxes for consumers, potentially bundle them over time, and they have a much better chance at getting exclusive games, thanks to the specificity of the hardware (something that's happened a lot for the Wii). Thus, both hardware manufacturers and publishers like EA see these controllers sparking new interest in Xbox 360 and PS3, which will delay the next dreaded console transition for another few years."

mariushm writes "Peter Cooper, the author of Beginning Ruby, breaks down how he gets paid for the book, including the advance and royalties, giving a nice clean explanation of how authors get paid for their books. He also describes the negotiations over the second edition of the book, in which he begged his publisher, Apress, to offer the ebook version for free, believing (strongly) that it would promote sales of the paper book. He even notes that the original version's ebook barely had noteworthy sales, so it seemed reasonable to offer up the ebook for free to drive more attention. No dice. Even though Apress has done that with other similar titles, it wouldn't agree. As he retains the copyright for the actual text, he encourages people to buy the book and create an online version of it without covers, contents table and indexes, promising not to enforce his copyright over the new work."

chrb writes "The NY Times Magazine has an interesting article about research, based on the long-running Framingham Heart Study, modeling real world social networks. It seems that tendencies to be happy, not to smoke, and not to become obese are passed between nodes in a directed graph in a way that suggests such concepts are 'contagious.' Well-connected nodes in the graph (i.e., people with more friends) are more likely to be happier than less-connected nodes, even when the edges represent more distant friendships. Individuals quitting smoking, or becoming obese, influence not only their immediately connected friends but also friends of friends, with the effect sometimes skipping the intermediary node. The contagion effect is most noticeable when a tendency is passed from one person to another of the same sex — friends of the opposite sex, including spouses, are not as influential."

Foot-in-Mouth writes "New Scientist reports that girls are more "primed" to fear spiders and snakes, compared to boys. Infant boys and girls were shown pairs of images, a fearful and a happy object (such as a spider and a flower), measuring the boys' and girls' dwell times on the images. And in another similar test, normally happy objects (such as a flower) were given a fearful face and fearful objects were given a happy face. The results of these two tests suggested to the researcher that girls are not wired to fear spiders, for example, but rather girls are wired to more quickly learn to fear dangerous animals. The researcher, David Rakison at CMU, 'attributes the difference to behavioural differences between men and women among our hunter-gatherer ancestors. An aversion to spiders may help women avoid dangerous animals, but in men evolution seems to have favoured more risk-taking behaviour for successful hunting.' This reminds one of men's obsession with video games. Will game designers use this information to tweak video games for gender, either to make the games more or less frightening?"

Hugh Pickens writes "Studies of reproduction in space have previously been carried out with sea urchins, fish, amphibians and birds, but Brandon Keim writes in Wired that Japanese biologists have discovered that although mammalian fertilization may take place normally in space, as mouse embryos develop in microgravity their cells have trouble dividing and maturing. The researchers artificially fertilized mouse eggs with sperm that had been stored inside a three-dimensional clinostat, a machine that mimics weightlessness by rotating objects in such a way that the effects of gravity are spread in every direction. Some embryos were ultimately implanted in female mice and survived to a healthy birth, but at lower numbers than a regular-gravity control group. Part of the difference could be the result of performing tricky procedures on sensitive cells, but the researchers suspect they also reflect the effect of a low-gravity environment on cellular processes that evolved for Earth-specific physics. '"These results suggest for the first time that fertilization can occur normally under G environment in a mammal, but normal preimplantation embryo development might require 1G," concludes the report. "Sustaining life beyond Earth either on space stations or on other planets will require a clear understanding of how the space environment affects key phases of mammalian reproduction."'"

puroresu writes "I currently reside in the UK. In recent years I've seen privacy, free expression and civil liberties steadily eroded, and I can't see anything changing for the better any time soon. With people being banned from the UK for expressing (admittedly reprehensible) opinions, the continuing efforts to implement mandatory ID cards and the prospect of a Conservative government in the near future, I'm seriously considering emigrating to a less restrictive country. Which countries would you recommend in terms of freedom and privacy? Distance is not an issue, though a reasonable level of stability and provision of public services would be a bonus."

Omomyid writes "In the seminal science fiction book 'Dune,' Frank Herbert envisioned the Fremen collecting water from the air via moisture traps and dew collectors. Science Daily reprints a press release from the Fraunhofer Institute in Stuttgart, where scientists working with colleagues from Logos Innovationen have developed a closed-loop and self-sustaining method, no external power required, for teasing the humidity out of desert air and into potable water."

A shoe-maker, Aetrex Worldwide, and GTX Corp, a company that makes miniaturized Global Positioning Satellite tracking and location-transmitting devices, are teaming up to make shoes for people suffering from Alzheimer's Disease. "The technology will provide the location of the individual wearing the shoes within 9m (30 feet), anywhere on the planet. Sixty per cent of individuals afflicted with Alzheimer's Disease will be involved in a 'critical wandering incident' at least once during the progression of the disease — many more than once," said Andrew Carle, an assistant professor at George Mason University who served as an advisor on the project. Not only will this technology allow a caretaker to find a loved one with a click of a mouse, but the shoes are more humanizing than a bell hung around the neck.

eldavojohn writes "What do you do when a foreign species has been introduced to your land from another continent? Bring over the natural predator from the other continent. Scientists in Texas have introduced four kinds of phorid flies from South America to fight fire ants. These USDA approved flies dive bomb ants and lay an egg inside the ant. The maggot hatches and eats away juicy tender delicious ant brain until the ant is nothing more than a zombie that wanders around for two weeks before the head falls off and the ant dies. A couple of these flies will cause the ants to modify their behavior and this will be a very slow acting solution to curb the $1 billion in damage these ants do to Texas cattle ranches and — oddly enough — electrical equipment like circuit breakers. You may remember zombifying parasites hitting insects like cockroaches."

KentuckyFC writes "Metamaterials are synthetic substances that can steer light in any way imaginable. Their most famous incarnation is in invisibility cloaks which work by steering light around a region of space making any object inside that region invisible. But invisibility is just the start. A team of physicists in Hong Kong (the same guys who recently worked out how to cloak objects at a distance) have worked out how to create a cloak that makes one object look like another. Instead of steering light to make a region of space look empty, the illusion cloak manipulates light in a way that makes a region of space look as if it contains a specific object. So any object within that region of space, a mouse say, takes on the appearance of an elephant."
