All-Analog DIY Segway Project 141

Posted by Soulskill on Saturday December 11, 2010 @07:54PM from the take-out-some-cliff-insurance-buddy dept.

An anonymous reader writes "One of the zany hacker-makers here at MIT just finished this DIY Segway project (video). Difference from the others: it's all analog. The controller is built without a microprocessor or even digital logic. It does use a gyroscope like the real Segway. The functionality looks fairly basic, but the fact that the controller works at all is amazing. The guy has a ton of other projects on his site too. Definitely worth a read for people who enjoy building things."

MIT Unveils Portable, Solar-Powered Water Desalination System 117

Posted by Soulskill on Tuesday October 19, 2010 @01:07AM from the water-the-chances dept.

An anonymous reader writes "A team from the Massachusetts Institute of Technology's Field and Space Robotic Laboratory has designed a new solar-powered water desalination system to provide drinking water to disaster zones and disadvantaged parts of the planet. Desalination systems often require a lot of energy and a large infrastructure to support them, but MIT's compact system is able to cope due to its ingenious design. The system's photovoltaic panel is able to generate power for the pump, which in turn pushes undrinkable seawater through a permeable membrane. MIT's prototype can reportedly produce 80 gallons of drinking water per day, depending on weather conditions."

Self-Assembling Photovoltaic Tech From MIT 128

Posted by Soulskill on Tuesday September 07, 2010 @05:17AM from the bright-ideas dept.

telomerewhythere writes "Michael Strano and his team at MIT have made a self-assembling and indefinitely repairable photovoltaic cell based on the principle found in chloroplasts inside plant cells. 'The system Strano's team produced is made up of seven different compounds, including the carbon nanotubes, the phospholipids, and the proteins that make up the reaction centers, which under the right conditions spontaneously assemble themselves into a light-harvesting structure that produces an electric current. Strano says he believes this sets a record for the complexity of a self-assembling system. When a surfactant is added to the mix, the seven components all come apart and form a soupy solution. Then, when the researchers removed the surfactant, the compounds spontaneously assembled once again into a perfectly formed, rejuvenated photocell.'"

NAMCO Takes Down Student Pac-man Project 218

Posted by Soulskill on Monday August 02, 2010 @06:30PM from the chasing-ghosts dept.

An anonymous reader writes "The core of how people first learn to do stuff — programming, music, writing, etc. — is to imitate others. It's one of the best ways to learn. Apparently a bunch of students using MIT's educational Scratch programming language understand this. But not everyone else does. NAMCO Bandai sent a takedown notice to MIT because some kids had recreated Pac-man with Scratch. The NAMCO letter is pretty condescending as well, noting that it understands the educational purpose of Scratch, but 'part of their education should include concern for the intellectual property of others.'"

The Mouse Vanishes 292

Posted by kdawson on Tuesday July 13, 2010 @01:12PM from the yesterday-upon-the-stair dept.

countertrolling sends in a clip from Wired that begins "...researchers at MIT have found a method to let users click and scroll exactly the same way they would with a computer mouse, without the device actually being there. Cup your palm, move it around on a table and a cursor on the screen hovers. Tap on the table like you would click a real mouse, and the computer responds. It's one step beyond cordless. It's an invisible mouse. The project, called 'Mouseless,' uses an infrared laser beam and camera to track the movements of the palm and fingers and translate them into computer commands... A working prototype of the Mouseless system costs approximately $20 to build, says Pranav Mistry, who is leading the project."

Neutrino Data Could Spell Trouble For Relativity 279

Posted by kdawson on Sunday June 27, 2010 @09:33PM from the stay-put-will-you dept.

Science News has an exploration of the deeper implications of neutrino oscillation, one experimental confirmation of which we discussed last month. "The new findings could even signal a tiny breakdown of Einstein's theory of special relativity. ... MINOS [for Main Injector Neutrino Oscillation Search] found that during a 735-kilometer journey from Fermilab to the Soudan Underground Laboratory in Minnesota, about 37 percent of muon antineutrinos disappeared — presumably morphing into one of the other neutrino types — compared with just 19 percent of muon neutrinos. ... That difference in transformation rates suggests a difference in mass between antineutrinos and neutrinos. ... With the amount of data collected so far, there's just a 5% probability that the two types of particles weigh the same."

MIT Says Natural Gas Best To Lower Carbon Emissions 284

Posted by Soulskill on Sunday June 27, 2010 @10:47AM from the pelican-friendly-solution dept.

eldavojohn writes "This week MIT released a comprehensive, hundred-page report entitled 'The Future of Natural Gas' that outlined the many scenarios the United States faces when aiming to reduce carbon emissions. From the New York Times recap: 'The scenario goes like this, according to MIT: Nuclear power, renewable energy, and carbon capture and sequestration are relatively expensive next to gas. Conventional coal is no longer a major source of power generation in the United States. "Natural gas is the substantial winner in the electric sector: The substitution effect, mainly gas generation for coal generation, outweighs the demand reduction effect."' Will this urging help to produce a policy shift from renewable energy (like wind) to natural gas for the United States?"

Visa Launches PayPal Alternative 141

Posted by samzenpus on Thursday June 24, 2010 @07:57AM from the lesser-of-two-evils dept.

An anonymous reader writes "Visa has entered the micropayment processing space with payclick, a pre-paid hosted service that will compete with the likes of PayPal. Payclick is aimed at teenagers purchasing online content like music and games where the value of the transaction is likely to be less than $20. Like PayPal, payclick is an online money repository that people can pay into with a bank account or credit card (Visa or MasterCard) and then use the funds to purchase products online. The service was developed and launched in Australia with a view for global markets. PayPal integration is not there yet, but parents can monitor the amount of funds their under-18 children have to spend online. For e-commerce sites, an SDK is available for payclick integration."

Seeing the Forest For the Trees 64

Posted by kdawson on Tuesday May 11, 2010 @05:18AM from the i-can-see-clearly-now dept.

swframe writes "A new object recognition system developed at MIT and UCLA looks for rudimentary visual features shared by multiple examples of the same object. Then it looks for combinations of those features shared by multiple examples, and combinations of those combinations, and so on, until it has assembled a model of the object that resembles a line drawing. Popular Science has a summary of the research. I've been working on something similar and I think this accomplishment looks very promising."

How To Exploit NULL Pointers 139

An anonymous reader writes "Ever wondered what was so bad about NULL pointer exceptions? An MIT Linux kernel programmer explains how to turn any NULL pointer into a root exploit on Linux. (There was also a previous installment about virtual memory and how to make NULL pointers benign.)"

Rupert Murdoch Hates Google, Loves the iPad 412

Posted by timothy on Wednesday April 07, 2010 @11:25PM from the consume-consume-consume dept.

Hugh Pickens writes "The Register reports that News Corp boss Rupert Murdoch, speaking at the National Press Club in Washington, reiterated his disgust at how search engines handle news and called on old media to rethink how their stories are distributed on the web. 'It's produced a river of gold, but those words are being taken mostly from the newspapers,' said Rupert. 'I think they ought to stop it, that the newspapers ought to stand up and let them do their own reporting.' Murdoch added that the iPad was a 'wonderful tool' for listening to music, watching videos and reading newspapers. 'It may well be the saving of the newspaper industry,' by making it cheaper to distribute content to a broader audience, Murdoch said. 'I'm old, I like the tactile experience of the newspaper,' Murdoch said. '(But) if you have less newspapers and more of these, that's OK. It doesn't destroy the traditional newspaper, it just comes in a different form.'"

Magnetism Can Sway Man's Moral Compass 586

Posted by CmdrTaco on Tuesday March 30, 2010 @03:00PM from the so-can-hot-chicks dept.

Hugh Pickens writes "Discovery News reports that scientists have identified a region of the brain which appears to control morality and discovered that a powerful magnetic field can scramble the moral center of the brain, impairing volunteers' notion of right and wrong. 'You think of morality as being a really high-level behavior,' says Liane Young, a scientist at MIT and co-author of the article. 'To be able to apply (a magnetic field) to a specific brain region and change people's moral judgments is really astonishing.' Young and her colleagues used functional magnetic resonance imaging to locate an area of the brain just above and behind the right ear known as the right temporo-parietal junction (RTPJ), which other studies had previously related to moral judgments. Volunteers were exposed to transcranial magnetic stimulation (TMS) for 25 minutes before reading stories involving morally questionable characters, and being asked to judge their actions. The researchers found that when the RTPJ was disrupted volunteers were more likely to judge actions solely on the basis of whether they caused harm — not whether they were morally wrong in themselves. The scientists didn't permanently remove the subjects' moral sensibilities and on the scientists' seven point scale, the difference was about one point, averaging out to about a 15 percent change, 'but it's still striking to see such a change in such high level behavior as moral decision-making.' Young points out that the study was correlation; their work only links the RTJP, morality, and magnetic fields, but doesn't definitively prove that one causes another."

If ET Calls, Who Speaks For Humanity? 371

Posted by timothy on Sunday March 21, 2010 @05:36PM from the your-call-is-very-important-to-us dept.

EagleHasLanded writes "Who speaks for humankind if ET calls on us? Paul Davies, chairman of the SETI Post-Detection Taskgroup, is a likely ambassador. But Allen Tough founded the Invitation to ETI Web site, which encourages ET to make contact via email (and also strongly discourages humans from impersonating ET). But an individual in the UK got over some of the hurdles designed to weed out hoaxers, before finally throwing in the towel."

MIT Developing Self-Assembling Computer Chips 65

An anonymous reader writes "Researchers at the Massachusetts Institute of Technology on have released research detailing how molecules in chips can self-assemble, potentially reducing manufacturing costs. The researchers have developed a technique in which polymers automatically fall into place to create an integrated circuit."

"Mythical Man-Month" Supposedly Busted By MIT Startup 231

Posted by samzenpus on Wednesday March 10, 2010 @09:15PM from the many-eyes-and-fingers dept.

An anonymous reader writes "We all know about the Mythical Man-Month, the argument that adding more programmers to a software project just makes it later and later. A Linux startup out of MIT claims to have busted the myth, using an MIT holiday month to hire 20 college student interns to get all their work done and quadrupling its productivity."
