Riding with Robots writes "The robotic geologist Opportunity has nearly reached the rim of Victoria Crater, which it is leaving after a year of exploration inside. Rover handlers decided to abandon attempts to approach the crater's cliff walls when they saw a power spike similar to the one that preceded a broken wheel on its twin, Spirit. Opportunity is already making do with a stuck robotic arm. The mission's manager said, 'Both rovers show signs of aging, but they are both still capable of exciting exploration and scientific discovery.' Opportunity is set to continue trekking across the Meridiani Plains of Mars, even though its wheels have already seen 10 times the use they were designed for. Meanwhile, Spirit has survived yet another harsh Martian winter to produce another striking panorama." Adam Korbitz notes other Mars-related news that funding has been approved for the Search for Extra-Terrestrial Genomes (SETG) Project. The project was one of 15 selected to receive funds through a NASA research opportunity program. The stated goal of the proposal is to "develop a PCR detector for in situ analysis on other planets, most immediately, Mars. This instrument is so sensitive it should allow the detection very low levels of microbial life on Mars, and will determine its phylogenetic position by analysis of the DNA sequence of the genes detected in situ."

snydeq sends along InfoWorld coverage of the EFF's plans to appeal a US District Court order that kept three MIT students from presenting detailed flaws in the Massachusetts Bay Transportation Authority e-ticketing system at Defcon. And an anonymous reader points out that the MBTA, in addition to triggering the Streisand Effect, released in open court more information on vulnerabilities (PDF) than the students had any intention of presenting. See Exhibit 1 to this court filing.

Adrian writes "Zack Anderson, an MIT student, created a solution to wardriving on a budget: warcarting. The Warcart is a shopping cart retrofitted with just about every sort of wireless sniffing device available. It has pivoting antennas and a smoke grenade launcher. It can even dispense infected USB flash drives. It's part of a talk about subway fare-collection-system vulnerabilities that will be given at Defcon 16 in a few days." "Mostly as a joke," says the site — but only mostly.

lindik writes "As part of their research efforts aimed at building real-time human-level artificial vision systems inspired by the brain, MIT graduate student Nicolas Pinto and principal investigators David Cox (Rowland Institute at Harvard) and James DiCarlo (McGovern Institute for Brain Research at MIT) recently assembled an impressive 16-GPU 'monster' composed of 8x9800gx2s donated by NVIDIA. The high-throughput method they promote can also use other ubiquitous technologies like IBM's Cell Broadband Engine processor (included in Sony's Playstation 3) or Amazon's Elastic Cloud Computing services. Interestingly, the team is also involved in the PetaVision project on the Roadrunner, the world's fastest supercomputer."

In 2004 we discussed the Piraha, a tribe in the Amazon, when a study appeared characterizing their language as a "one, two, many" language. Now reader mu22le informs us of a new study of the Piraha pointing to the possibility that they use no number words at all. Instead they seem to use the word formerly thought to mean "two" to represent a quantity of 5 or 6, and the "one" word for anything from 1 to 4. The language has about 300 native speakers. "The study... offers evidence that number words are a concept invented by human cultures as they are needed, and not an inherent part of language, Gibson said."

Hugh Pickens writes "About 60 people from 20 nations will descend on the MIT campus July 14th for the second annual International Development Design Summit to begin an intensive month-long process of creating technological solutions for the needs of people in the world's developing nations. The goal of the program is to develop simple, inexpensive devices that in some cases can be produced locally and make a real difference for people and communities. The event is the brainchild of MIT Senior Lecturer Amy Smith, a returned Peace Corps volunteer and a past winner of the MacArthur 'genius' grant. Previous products of Smith's design class include a bike-powered corn sheller, a metal press that can make clean-burning fuel out of agricultural waste, and an electricity-free incubator. The workshop promotes a shift in focus among companies, universities, investors and scientists toward attacking problems that hamper development in the world's poorest places. 'Nearly 90 percent of research and development dollars are spent on creating technologies that serve the wealthiest 10 percent of the world's population,' Ms. Smith said. 'The point of the design revolution is to switch that.'"

Vegematic writes "Researchers at MIT have improved solar collectors using dyes. They just increased their performance results by a factor of 4. These paint-on materials can increase the power obtained from existing solar cells by a factor of over 40 without needing to track the sun. 'By collecting light over their full surface and concentrating it at their edges, these devices reduce the required area of solar cells and consequently, the cost of solar power. Stacking multiple concentrators allows the optimization of solar cells at each wavelength, increasing the overall power output.' There is also a shorter FAQ available."

I Don't Believe in Imaginary Property writes "The folks at Kaspersky labs are turning to distributed computing to factor the RSA key used by the GPcode virus to encrypt people's files and hold them for ransom. There are two 1024-bit RSA keys to break, which should require a network of about 15 million modern computers to spend a year per key factoring them. Unfortunately, there appear to be no vulnerabilities in the virus' use of RSA, unlike some previous cases. Perhaps more interestingly, there's some debate over whether people should bother cracking it. After all, what if they were trying to trick us into factoring the key for a root signing authority? Besides, there's a more direct method of breaking the encryption: track down the people who wrote the virus and force them to talk."

TheUnknownCoder writes "MIT scientists have created a Nanowire mesh that can selectively absorb hydrophobic (oil-like) liquids from water up to 20 times its weight. The membrane can be recycled many times for future use, and the oil itself can also be recovered. There's even a video of it in action, removing gasoline from water."

Roland Piquepaille alerts us to work by US and Israeli researchers who have developed software that can identify the subject of an image characterized using only 256 to 1024 bits of data. The researchers said this "could lead to great advances in the automated identification of online images and, ultimately, provide a basis for computers to see like humans do." As an example, they've picked up about 13 million images from the Web and stored them in a searchable database of just 600 MB, making it possible to search for similar pictures through millions of images in less than a second on a typical PC. The lead researcher, MIT's Antonio Torralba, will be presenting the research next month at a conference on Computer Vision and Pattern Recognition.

sas-dot writes "The most sought-after Indian institutions like IIT and IISc have put their course lectures on YouTube. The site is up from last December and is slowly gaining momentum in terms of lectures available online. This is India's own program similar to MIT's OpenCourseWare. Good to see the competition, and that students have many sources of knowledge for free."

jcatcw writes "Steven J. Vaughan-Nichols considers the dissimilarities between malware of yore and current infiltrations as we approach the 20th anniversary of the Robert Morris worm. Modern malware apps curl up and make themselves at home in your system, where they wait for a chance to snatch an important password or a credit card number. Welcome to the era of capitalist hacking. Any self-respecting malware program today is polymorphic, making signature-based antivirus approaches difficult. Heuristics and virtual sandboxes offer alternatives, but all such methods are reactive. Unfortunately, monitoring lists and networks is about the only current alternative."

An anonymous reader writes "Professor Edward N. Lorenz, who discovered in 1961 that subtle changes in the initial conditions of a weather simulation program could cause very large differences in its results, died of cancer Wednesday at the age of 90. The contributions of the father of chaos theory, who coined the term 'the butterfly effect' and also discovered the Lorenz Attractor, are best summarized by the wording of the Kyoto Prize in 1991 which noted that his discovery of chaos theory 'profoundly influenced a wide range of basic sciences and brought about one of the most dramatic changes in mankind's view of nature since Sir Isaac Newton.'"

NoMoreCoal writes "Salon has up a story by Joe Romm, former undersecretary of energy during the Clinton administration, discussing a lesser-known alternative energy solution. It's a technology that (he claims) is ready to provide zero-carbon electric power big, fast, cheap and (most importantly) right now: solar thermal power. 'Improvements in manufacturing and design, along with the possibility of higher temperature operation, could easily bring the price down to 6 to 8 cents per kilowatt hour. CSP makes use of the most abundant and free fuel there is, sunlight, and key countries have a vast resource. Solar thermal plants covering the equivalent of a 92-by-92-mile square grid in the Southwest could generate electricity for the entire United States. Mexico has an equally enormous solar resource. China, India, southern Europe, North Africa, the Middle East and Australia also have huge resources.'" Interesting stuff, even if he does mention the Archimedes Death Ray.

An anonymous reader writes "MIT and Texas Instruments researchers have designed a chip that they say could be up to 10 times more energy efficient than current technology. The chip's power consumption is so low that devices with the chip may even be able to be recharged using the owner's body heat." The intent is to use these in medical applications like pacemakers where one would expect to have the free power source.

Gibbs-Duhem writes "An MIT graduate student has up a page showcasing a standout art project. He's designed custom LED light fixtures which are seven times brighter than the closest similar commercial models, and include colors which can't be reproduced by a normal RGB cluster (including two ridiculously bright UV LEDs). The result: some beautiful mixed media artwork. The author's goal is to eventually publish a guide to make getting into creating such artwork more accessible to the general public. The site includes lots of great photos and a movie of the art in action. It also has in depth descriptions of the theory involved in this relatively new form of art, an explanation of how the paints were chosen, and an in depth technical discussion of how such lights are designed with schematics and board layouts for those who might wish to build their own lights."

The Narrative Fallacy brings news that NASA has awarded a $500,000 grant to develop plans for an array of radio telescopes to be located on the moon. The telescopes would be used to gather data from the earliest stars and galaxies, observations of which are difficult from Earth due to the ionosphere and terrestrial broadcasts. The grant was part of NASA's sponsoring of 19 "Next Generation Astronomy Missions." Quoting: "The Lunar Array for Radio Cosmology (LARC) project ... is planned as a huge array of hundreds of telescope modules designed to pick up very-low-frequency radio emissions. The array will cover an area of up to two square kilometers; the modules would be moved into place on the lunar surface by automated vehicles. The new lunar telescopes would add greatly to the capabilities of a low-frequency radio telescope array now under construction in Western Australia, one of the most radio-quiet areas on Earth."

Roland Piquepaille writes "A major challenge in public health is that people do not take their medications, a phenomenon known as 'medication non-adherence.' In the US alone, it is estimated that this accounts for 10% of all hospital visits and costs the healthcare system $100 billion per year and $60 billion to the pharmaceutical industry. Now, an MIT research team thinks it has a solution to this problem that will save lives worldwide. They've developed the uBox, a convenient, palm-sized, intelligent pill dispenser, 'which reminds a patient when it is time to take his medication, records when a patient has taken a dose, and prevents a patient from double-dosing.' The first large-scale trial with 100 uBoxes is scheduled to begin in May in Bihar, India, in a 6-month long tuberculosis treatment program."

NewYorkCountryLawyer writes "MIT's online newspaper, The Tech, reports that a student named as a John Doe by the RIAA is planning to fight back against their questionable legal tactics. The anonymous student told The Tech that he is 'the victim of a fishing expedition by the RIAA,' and is 'disappointed that MIT isn't going to step up ... Other schools like Boston University and the University of Oregon have resisted RIAA subpoenas of student records more actively than MIT has, he said'. Maybe his attorneys will be able to get some assistance from some of the Harvard Law School students in Professor Nesson's 'Evidence' class, who have been assigned — as part of their coursework — the drafting of a motion to quash an RIAA subpoena."

An anonymous reader writes "The effects of mobile phone radiation on sleep were studied in Sweden in a laboratory experiment where subjects were exposed either to 884 MHz GSM radiation or placebo. The study finds that compared to placebo, in the radiation-exposed subjects there was a prolonged latency to reach the first cycle of deep sleep (stage 3). The amount of stage 4 sleep was also decreased. Moreover, participants that otherwise have no self-reported symptoms related to mobile phone use, appear to have more headaches during actual radiofrequency exposure as compared to sham exposure."

PCOL writes "When Conquistadors came to Peru from Spain in 1532, they were astonished to see Inca suspension bridges achieve clear spans of at least 150 feet at a time when the longest Roman bridge in Spain had a maximum span of 95 feet. The bridges swayed under the weight of traffic terrifying the Spanish and their horses, even though, as one Spaniard observed, they were almost as "sturdy as the street of Seville." To build the bridges, thick cables were pulled across a river with small ropes and attached to stone abutments on each side. Three of the big cables served as the floor of the bridge, two others served as handrails and pieces of wood were tied to the cable floor before the floor was strewn with branches to give firm footing for beasts of burden. Earlier this year students at MIT built a 70-foot fiber bridge in the style of the Incan Empire. The project used sisal twine from the Yucatan Peninsula and anchored it by wrapping it around massive concrete blocks. The weekend's burst of activity was preceded by 360 hours of rope-twisting as the 50 miles of sisal twine was turned into rope. Working together as a group was part of the exercise. "A third of the time was spent learning to work together," one of the students said. "But after a while, we were banging those cables out.""

mlauzon writes "Extraordinary news for computer scientists and the Open Source community was announced over the weekend, as the source code of the MULTICS operating system (Multiplexed Information and Computing Service), the father of UNIX and all modern OSes, has finally been opened. Multics was an extremely influential early time-sharing operating system and introduced a large number of new concepts, including dynamic linking and a hierarchical file system. It was extremely powerful, and UNIX can in fact be considered to be a 'simplified' successor to MULTICS. The last running Multics installation was shut down on October 31, 2000. From now on, MULTICS can be downloaded from an official MIT site (it's the complete MR12.5 source dumped at CGI in Calgary in 2000, including the PL/1 compiler). Unfortunately you can't install this on any PC, as MULTICS requires dedicated hardware, and there's no operational computer system today that could run this OS. Nevertheless the software should be considered to be an outstanding source for computer research and scientists. It is not yet known if it will be possible to emulate the required hardware to run the OS."

phooky writes "Although open teaching materials have been available at the university level for a while now, there have been very few materials for younger learners. That's beginning to change now with the advent of Free-Reading, a free, wiki-based resource for early literacy instruction. The availability of free materials could free up millions of dollars from school budgets for more teachers and training. From the USA Today article: 'Last fall, a Florida textbook adoption committee approved Free-Reading, a remediation program for primary-school children that's believed to be the first free, open-source reading program for K-12 public schools. It's awaiting approval by Eric Smith, the state's incoming education commissioner, who could approve it by mid-December. Florida is one of the top five textbook markets in the USA, so its move could lead to the development of other free materials that might someday challenge the dominance of a handful of big educational publishers.'"

SoyChemist writes "Forty years ago, LOGO, a derivative of LISP, was born. Several years later, it became the cornerstone of educational software that simultaneously taught geometry and how to think like a coder. With a plethora of high-end educational software packages to choose from, each with flashy multimedia and trademarked characters, parents and teachers may find the humble turtle a bit outdated. Thankfully, several LOGO programs are available for free through a variety of websites, but perhaps 3D programming environments like Alice will be the wave of the future."

The Singularity refers to the creation of smarter-than-human intelligence beyond which the future becomes unpredictable. The concept of the Singularity sounds more daunting in the form described by statistician I.J Good in 1965: 'Let an ultra-intelligent machine be defined as a machine that can far surpass all the intellectual activities of any man however clever. Since the design of machines is one of these intellectual activities, an ultra-intelligent machine could design even better machines; there would then unquestionably be an 'intelligence explosion,' and the intelligence of man would be left far behind. Thus the first ultra-intelligent machine is the last invention that man need ever make.'"

MIT scientists and colleagues have found a way in the lab to create large amounts of cancer stem cells, the cells that can initiate tumors.

Cain writes to mention that a couple of MIT students would like to harness the mechanical power of large groups of people. "A Crowd Farm in Boston's South Station railway terminal would work like this: A responsive sub-flooring system made up of blocks that depress slightly under the force of human steps would be installed beneath the station's main lobby. The slippage of the blocks against one another as people walked would generate power through the principle of the dynamo, a device that converts the energy of motion into that of an electric current."

Details about WiTricity, or wireless electricity, are scheduled to be reported today in Science Express, the advance online publication of the journal Science, the Massachusetts Institute of Technology said. 'The team from MIT is not the first group to suggest wireless energy transfer. Nineteenth-century physicist and engineer Nikola Tesla experimented with long-range wireless energy transfer, but his most ambitious attempt - the 29m high aerial known as Wardenclyffe Tower, in New York - failed when he ran out of money. Others have worked on highly directional mechanisms of energy transfer such as lasers. However, unlike the MIT work, these require an uninterrupted line of sight, and are therefore not good for powering objects around the home.'"

Reader Hanji alerts us to a hack pulled off when Randall Munroe, author of the popular webcomic XKCD, spoke at MIT by invitation of the Lab for Computer Science. MIT hackers dropped hundreds of labelled playpen balls onto the audience from hatches in the ceiling. The labels bore XKCD's logo as well as the recently discovered 16-byte AACS processing key. At another point in Munroe's talk he was stalked by remote-controlled mechanical velociraptors; but fortunately he had been supplied with a squirt gun full of grape juice.

An anonymous reader passed us a link to an article on the Boston Globe's website, talking up efforts by MIT to make programming a non-threatening part of grade-school education. MIT has developed a new programming language designed to encourage experimentation and play. Called Scratch, the project eschews manuals and high-level concepts in favour of approachability. "Efforts to make computer programming accessible to young people began in the late 1970s with the advent of the personal PC, when another programming language with roots at MIT — Logo — allowed young people to draw shapes by steering a turtle around a screen by typing out commands. But the path to mastering most programming languages has been strewn with obstacles, since students needed to figure out not only the underlying logic but also master a brand new syntax, observe strict rules about semicolons and bracket use, and figure out what was causing error messages even as they learned the program."

An anonymous reader writes "The MIT home-page story today is about a way to use light to shut down brain activity. "Scientists at the MIT Media Lab have invented a way to reversibly silence brain cells using pulses of yellow light, offering the prospect of controlling the haywire neuron activity that occurs in diseases such as epilepsy and Parkinson's disease."

Gibbs-Duhem writes with news that MIT has dropped its subscription to the Society of Automotive Engineers' web-based database of technical papers over the issue of DRM. The SAE refuses to allow any online access except through an Adobe DRM plugin that limits use and does not run on Linux or Unix. Also, the SAE refuses to let its papers even be indexed on any site but their own. SAE's use of DRM is peculiar to say the least, as they get their content for free from the researchers who actually do the work. And those researchers have choices as to where they send their work, and some of the MIT faculty are pretty vocal about it. From the MIT Library News: "'It's a step backwards,' says Professor Wai Cheng, SAE fellow and Professor of Mechanical Engineering at MIT, who feels strongly enough about the implications of DRM that he has asked to be added to the agenda of the upcoming SAE Publication Board meeting in April, when he will address this topic."
