iONiUM writes "From the article: 'Many are only just getting their heads around the idea of 3D printing but scientists at MIT are already working on an upgrade: 4D printing. At the TED conference in Los Angeles, architect and computer scientist Skylar Tibbits showed how the process allows objects to self-assemble.' There could be many applications for this. Definitely a cool step forward." Pictures and video of the process.

The US Department of Homeland Security is studying lies, damned lies, and smells. They hope to prove that human body odor could be used to tell when people are lying. The department says they are already "conducting experiments in deceptive behavior and collecting human odor samples" and that the research it hopes to fund "will consist primarily of the analysis and study of the human odor samples collected to determine if a deception indicator can be found."

Singularity Hub writes "For decades our options for interacting with the digital world have been limited to keyboards, mice, and joysticks. Now with a new generation of exciting new interfaces in the pipeline our interaction with the digital world will be forever changed. Singularity Hub looks at some amazing demonstrations, mostly videos, that showcase new ways of interacting with the digital world." Along similar lines, reader shakuni points out a facial expression-driven user interface reported on News.com for operating, say, an iPhone, explaining "This device is tiny and fits into the ear and measures movements inside the ear due to changes in facial expression and then uses that as input triggers. So [tongue out] starts or stops your iPod Touch; [Wink] rewinds to the last song; and [smile] replays the same song."

sparky1240 writes "While Americans are currently fighting the net-neutrality wars, spare a thought for the poor Australians — The Australian government wants to implement a nation-wide 'filtering' scheme to keep everyone safe from the nasties on the internet, with no way of opting out: 'Under the government's $125.8 million Plan for Cyber-Safety, users can switch between two blacklists which block content inappropriate for children, and a separate list which blocks illegal material. ... According to preliminary trials, the best Internet content filters would incorrectly block about 10,000 Web pages from one million."

Roland Piquepaille notes the hype surrounding what the University of Texas at Austin is calling the world's most powerful laser. During a tenth of a femtosecond this laser is 2,000 times more powerful than all the power plants in the US, and is brighter than sunlight on the surface of the Sun. On his own blog Roland points out that UT's is not the first petawatt laser; that distinction belongs to a system installed at Lawrence Livermore National Laboratory in 1996.

jason writes "YouTube has never really been known for streaming videos at a high resolution, but it appears that they are taking early steps at providing higher quality videos. The project was announced last year by the site's co-founder Steve Chen, and now appears to be in the earliest stages of deployment. By adding a parameter onto the end of a video's URL you're able to watch it in a higher quality (in terms of audio and video) that is actually quite noticeable. Not all videos have been converted at this point, but they do have millions upon millions of videos that they need to do."

Nick Kilkenny sends us an AP article on the imminent shutdown of the US analog cellular network, now 24 years old. The network is scheduled to go dark on Feb. 18, 2008; some users, such as OnStar, are stopping analog service at the end of this year. Here's a list of devices and industries that will be affected by the shutdown. (Cellular telephony won't be affected much.) "The shutdown date has been known years in advance, but some industries appear to have a had a problem updating their technologies and informing their customers in advance... General Motors Corp., which owns OnStar, started modifying its cars after the 2002 decision by the Federal Communications Commission to let the network die, but some cars made as late as 2005 can't use digital networks for OnStar, nor can they be upgraded. For some cars made in the intervening years, GM provides digital upgrades for $15." Update: 12/22 22:25 GMT by KD : Replaced two registration-required links.

lottameez recommends an article in the Washington Post about recent research into the persistence of myths. In short: once a myth has been put out there (e.g., "Saddam Hussein plotted the 9/11 attacks"), denying it can paradoxically reinforce its staying power. Ignoring it doesn't work either — a claim that is unchallenged gains the ring of truth. Over time, "negation tags" fall out of memory: "Saddam didn't plan 9/11" becomes "Saddam planned 9/11." From the article: "The conventional response to myths and urban legends is to counter bad information with accurate information. But the new psychological studies show that denials and clarifications, for all their intuitive appeal, can paradoxically contribute to the resiliency of popular myths... The research is painting a broad new understanding of how the mind works. Contrary to the conventional notion that people absorb information in a deliberate manner, the studies show that the brain uses subconscious 'rules of thumb' that can bias it into thinking that false information is true. Clever manipulators can take advantage of this tendency."

An anonymous reader clues us to research at Japan's National Institute of Advanced Industrial Science and Technology that has produced the ability to make animations by creating small plasma balls in mid-air. The technology doesn't use vapor or strange gases, just lasers to heat up oxygen and nitrogen molecules above the device: up to 1,000 brilliant dots per second, which makes smooth motion possible. When the tech improves it could be used for street signs or advertising.
