theodp writes "The NY Times takes a look at how MIT ensnared Aaron Swartz, but doesn't shed much light on how the incident became a Federal case with Secret Service involvement. Still, the article is interesting with its report that 'E-mails among M.I.T. officials that Tuesday in January 2011 highlight the pressures university officials felt' from JSTOR, which is generally viewed as a good guy in the incident. From the story: 'Ann J. Wolpert, the director of libraries, wrote to Ellen Finnie Duranceau, the official who was receiving JSTOR's complaints: "Has there ever been a situation similar to this when we brought in campus police? The magnitude, systematic and careful nature of the abuses could be construed as approaching criminal action. Certainly, that's how JSTOR views it."' Less than a week later, a Google search reveals, Duranceau notified the MIT community that immediate changes to JSTOR access had to be made lest the University be subjected to a JSTOR 'death sentence.' 'Because JSTOR has recently reported excessive, systematic downloading of articles at MIT,' the post warned, 'we need to add a new layer of access control. This is the only way to prevent recurrence of the abuse and therefore the only way to ensure ongoing access to this valuable resource for the MIT Community.' The post concludes, 'The incidents that prompted this change involved the use of a robot, which is prohibited by JSTOR's Terms and Conditions of Use. ...Continued access to JSTOR and other resources is dependent on the MIT Community complying with these policies.'

MassDosage writes "I first heard about the Scratch programming language a few years ago and the idea of a simple language designed to teach kids to program in a fun, new way has always appealed to me. For those of you who don't know, Scratch was developed by the wonderfully named "Lifelong Kindergarten Group" at the MIT Media Lab. It's a programming language that allows programs to be built by dragging, dropping, configuring and combining various blocks that represent common coding concepts such as if/else statements and while loops. Scratch also provides tools for doing simple animation, playing audio and controlling sprites. The idea behind it is to make programming simple, fun and accessible to first time programmers so they can understand the key concepts without first needing to learn complex syntax which can come later when they move on from Scratch to other languages. It has been very successful and there are literally millions of Scratch programs freely available from the Scratch website and many others." Read below for the rest of Mass Dosage's review. Super Scratch Programming Adventure!: Learn to Program By Making Cool Games author The LEAD Project pages 160 publisher The LEAD Project rating 7/10 reviewer Mass Dosage ISBN 978-1-59327-409-2 summary Learn to Program By Making Cool Games The Super Scratch Programming Adventure book has recently been translated from the Chinese original and is in keeping with the Scratch ethos of bringing programming to a new generation of programmers. It is hard to tell what the age group for this book is as children have such varied technical skills but I would say it's best for relatively computer savvy youngsters who know the basics of computing and are comfortable with a mouse and keyboard and know how to drag, drop, open, save, cut, paste etc. It should be suitable for ages from 8 up to young teenagers but even those a bit older looking to learn programming could find it useful while younger children might also be able to get something out of it if guided by someone older.

The book starts of with a bit of background and points the reader to where they can freely download and install the Scratch application which is used to create Scratch programs. This is available for Windows, Mac and Linux and was a breeze to install on Ubuntu Linux. All programming is done via a GUI to avoid having to deal with typos and syntax errors. The Scratch environment is fairly simple and intuitive and easy to get started with. A downloadable zip file accompanies the book and contains skeleton programs with sound and images that are used for creating applications as well as fully complete programs which can be used for reference if you get stuck creating your own versions. The zip file also contains a "Getting started with Scratch" guide that is a very useful prelude to the book if you've never used Scratch before and covers the main concepts and tools that are used in the book itself. It is important to note that this book is not a manual for Scratch and doesn't provide exhaustive coverage of what Scratch can do or how to use all of its features. Super Scratch Programming Adventure takes a "learn by doing" approach by guiding you through the creation of a few programs and leaves you to figure the rest out yourself. Given the target audience this makes a lot of sense — most youngsters would much rather build some cool applications right away than wade through lots of dry documentation first.

Super Scratch Programming Adventure is divided into various "stages" (computer game speak for "chapters") that are linked by a colorful cartoon adventure story. Each stage guides the reader through creating a computer game from... err... scratch and teaches them some fundamental concepts along the way. Later stages build on lessons learnt earlier so they should be read in order and the book steers one towards this with the cartoon linking what you do in the various stages together as you build games which in turn become part of the story. The early stages start off showing how to use sprites and move them around and how to use the palette to build up programs and attach behaviors to things. Later stages cover user input, broadcasting and reacting to events, flow control, collision detection, variables, animation and audio with each stage harder than the previous one right up until the final stage which involves creating a fighting game with numerous sprites and interactions between them and the user. I found all the games fun to build and use and could definitely see the distinct lessons each one was designed to teach.

The learning curve is a bit higher than I expected and there is little hand holding, at some points you just have to look at the included code blocks and figure out yourself how to build them up. It's not always easy and readers will need to be fairly computer literate and able and willing to figure a fair amount out on their own but ultimately this is probably a good thing as explaining everything in minute detail would take a lot longer, be quite boring and would lead some to just blindly copying things instead of being forced to understand what they are doing. I could imagine that some young readers might find this a bit challenging so it's probably a good idea to have a computer literate adult around to help out if they get stuck. The included complete source for each game also helps although looking at this does feel a bit like cheating. Each stage ends with suggestions for further programming on ones own and I felt that these are really the key for this book to succeed as a learning tool as these make one think about and apply what was just read. Again I think this would be a good point for a parent or someone older to step in and encourage a younger reader to build on what they've learnt and suggest creating something new for themselves. The book contains plenty of pointers to online resources where readers can learn more, ask questions and share their creations with others.

I would definitely recommend Super Scratch Programming Adventure for those eager to learn programming but be aware that to really get the most out of it it's probably best if someone who already knows how to program is around to read along, help out and encourage further creation outside of what the book shows. There is a wealth of Scratch related information on the internet but this book provides a good way to get started by demonstrating how to build fun applications and hopefully this in turn will encourage readers to move on to creating more on their own.

Full disclosure: I was given a copy of this book free of charge by the publisher for review purposes. They placed no restrictions on what I could say and left me to be as critical as I wanted so the above review is my own honest opinion.

theodp writes "The e-mail that Defendant Swartz's supplemental memorandum (pdf) cites as paramount to his fifth motion to suppress [evidence against him] is relevant, but not nearly as important as he tries to make it out to be,' quipped United States Attorney Carmen M. Ortiz (pdf) in a court filing made on the same day Aaron Swartz committed suicide. In the 1-7-2011 e-mail Ortiz refers to, which was not produced for Swartz until Dec. 14th — almost two years after his 1-6-2011 arrest — a Secret Service agent reported to the Assistant U.S. Attorney that he was 'prepared to take custody anytime' of Swartz's laptop, although no one had yet sought a warrant to search the computer. In Prosecutor as Bully, Larry Lessig laments, 'They [JSTOR] declined to pursue their own action against Aaron, and they asked the government to drop its. MIT, to its great shame, was not as clear, and so the prosecutor had the excuse he needed to continue his war against the "criminal" who we who loved him knew as Aaron.' Swartz's family also had harsh words for MIT and prosecutors: 'Decisions made by officials in the Massachusetts U.S. Attorney's office and at MIT contributed to his death. The US Attorney's office pursued an exceptionally harsh array of charges, carrying potentially over 30 years in prison, to punish an alleged crime that had no victims. Meanwhile, unlike JSTOR, MIT refused to stand up for Aaron.' With MIT President Emeritus Charles M. Vest currently serving as a Trustee of JSTOR parent Ithaka as well as a Trustee of The MIT Corporation, one might have expected MIT to issue a statement similar to the let's-put-this-behind-us one JSTOR made on the Swartz case back in 2011."

maijc writes "Computer activist Aaron Swartz committed suicide yesterday in New York City. He was 26 years old. Swartz was 'indicted in July 2011 by a federal grand jury for allegedly mass downloading documents from the JSTOR online journal archive with the intent to distribute them.' He is best known for co-authoring the widely-used RSS 1.0 specification when he was 14, and as one of the early co-owners of Reddit."

An anonymous reader writes "A new technique allows allows 'thermocrystals' to be created that can manipulate heat (a vibration of the atomic lattice of a material). Predicted manipulations include the ability to selectively transmit, reflect or concentrate heat much like light waves can be manipulated by lenses and mirrors. 'Heat differs from sound, he explains, in the frequency of its vibrations: Sound waves consist of lower frequencies (up to the kilohertz range, or thousands of vibrations per second), while heat arises from higher frequencies (in the terahertz range, or trillions of vibrations per second).' Applications range from better thermoelectric devices to switchable heat insulating/transmitting materials (abstract). Perhaps this will result in better cooling/heating mechanisms or more efficient engines."

Velcroman1 writes "Teenagers raised on Call of Duty and Halo might relish flying a massive Predator drone — a surprisingly similar activity. Pilots of unmanned military aircraft use a joystick to swoop down into the battlefield, spot enemy troop movements, and snap photos of terror suspects, explained John Hamby, a former military commander who led surveillance missions during the Iraq War. 'You're always maneuvering the airplane to get a closer look,' Hamby said. 'You're constantly searching for the bad guys and targets of interest. When you do find something that is actionable, you're a hero.' Yet a new study at the Massachusetts Institute of Technology found real-life drone operators can become easily bored. Only one participant paid attention during an entire test session, while even top performers spent a third of the time checking a cellphone or catching up on the latest novel. The solution: making the actual drone mission even more like a video game."

Covalent writes "The Large Hadron Collider, the world's largest and most powerful particle accelerator and the 'Big Bang machine' that was used to discover what appears to be the long-sought Higgs boson particle (as announced July 4), may have another surprise up its sleeve this year: The LHC looks to have produced a new type of matter, according to a new analysis of particle collision data by scientists at MIT and Rice University. The new type of matter, which has yet to be verified, is theorized to be one of two possible forms: Either 'color-glass condensate' — a flattened nucleus transformed into a 'wall' of gluons, which are smaller binding subatomic particles, or it could be 'quark-gluon plasma,' a dense, soup or liquid-like collection of individual particles."

cervesaebraciator writes "A 'Coffee Branding Workshop,' sponsored by the World Intellectual Property Organization, was held recently in Arusha City, at which the Director General of the Tanzania Coffee Board presented a paper titled 'Supporting the Coffee Sector with added Value Products Through Intellectual Property and Branding.' The paper encouraged the use of intellectual property claims, including trademarks, copyrights, patents, and designs, as sources of income which can be used to support agriculture in Africa. The Director General claimed that '[Intellectual property rights] are the basis for today's knowledge based economy and international competitiveness.' This is no doubt related to a broader effort to advance western style intellectual property in Africa through claims of the benefits it offers agriculture. Promoting western style intellectual property law as a means of third world development is a popular strategy for WIPO, the only branch of the UN to have significant wealth deriving from contributions independent of Member States. On a related note of interest to Slashdotters, there is a history of tension between WIPO advocates and FOSS advocates." I hope they take advantage of the marketing possibilities offered by civet-processed coffee.

Nwe submitter arrow3D writes "A new startup in Norway is focused on design and fabrication at the level and quality of nature. Using pure mathematical volumes, rather than surfaces or voxels, they are developing a new generation of 3D modelling tools specifically aimed at high resolution 3D printing, to 'support the future of design and manufacturing.' Their software was recently used to create the multi-material Minotaur Helmet by Neri Oxman from MIT, as featured in Wired UK last month. An interesting thought (as recently illustrated in Dilbert) is the idea of a Physical Turing Test for synthetic objects and that both Turing Tests may require each other — i.e. only by designing and building at the resolution of nature can we achieve the intelligence of natural objects. Their software platform is still very much under development but they've started trying to 'save the world from polygons' with a KickStarter campaign that's live now."

cylonlover writes "Our ears work by converting the vibrations of the eardrum into electrochemical signals that can be interpreted by the brain. The current for those signals is supplied by an ion-filled chamber deep within the inner ear – it's essentially a natural battery. Scientists are now looking at using that battery to power devices that could be implanted in the ear, without affecting the recipient's hearing. The 'battery chamber' is located in the cochlea. It is internally divided by a membrane, some of the cells of which are designed to pump ions. The arrangement of those specialized cells, combined with an imbalance of potassium and sodium ions on opposite sides of the membrane, are what creates the electrical voltage. A team of scientists from MIT, the Massachusetts Eye and Ear Infirmary, and the Harvard-MIT Division of Health Sciences and Technology have recently succeeded in running an ultra-low-power radio-transmitting chip using power from these battery chambers – in guinea pigs' ears."

New submitter schirra writes "Researchers at MIT Game Lab have created a free video game that accurately simulates the effects of Einstein's relativity. 'A Slower Speed of Light' challenges players to collect objects strewn throughout a level to artificially lower the speed of light. As light speed slows to walking pace, it makes visible the unusual effects one encounters when traveling close to the speed of light, such as the Doppler effect, searchlight effect and Lorentz transformation. The effects are, in a word, trippy. The team plans to release an open-source Unity3D toolkit called OpenRelativity to allow others to include the same relativistic effects in other games." They also plan to release the source code sometime next year (despite reports that it is open source already).

hypnosec writes "Two MIT electrical engineering professors, Joel Dawson and David Perreault, have claimed that they have cracked the age old efficiency problem related to the power amplifier in smartphones by designing a new amplifier that consumes just half the power as compared to their current counterparts. Current transistor-based power amplifiers consume power in two modes – standby and output signal mode. The only way to reduce power consumption and increase battery life is to use the least possible power when in standby mode. The problem here is that if the power is kept very low when in standby mode, because of sudden jumps from low-power standby mode to high-power output mode, signals get distorted. This is why current technologies waste a lot of electricity as standby power levels are kept at a relatively higher level to avoid distortion. The new technology, dubbed asymmetric multilevel outphasing, is basically a blazingly fast electronic gearbox that would select the best possible voltage to send across to the transistors that would minimize power consumption."

SternisheFan sends this quote from an article at MIT's Technology Review: "In the event that a giant asteroid is headed toward Earth, you’d better hope that it’s blindingly white. A pale asteroid would reflect sunlight — and over time, this bouncing of photons off its surface could create enough of a force to push the asteroid off its course. How might one encourage such a deflection? The answer, according to an MIT graduate student: with a volley or two of space-launched paintballs. Sung Wook Paek, a graduate student in MIT’s Department of Aeronautics and Astronautics, says if timed just right, pellets full of paint powder, launched in two rounds from a spacecraft at relatively close distance, would cover the front and back of an asteroid, more than doubling its reflectivity, or albedo. The initial force from the pellets would bump an asteroid off course; over time, the sun’s photons would deflect the asteroid even more."

MrSeb writes "A team of researchers from MIT, Caltech, Harvard, and other universities in Europe, have devised a way of boosting the performance of wireless networks by up to 10 times — without increasing transmission power, adding more base stations, or using more wireless spectrum. The researchers' creation, coded TCP, is a novel way of transmitting data so that lost packets don't result in higher latency or re-sent data. With coded TCP, blocks of packets are clumped together and then transformed into algebraic equations (PDF) that describe the packets. If part of the message is lost, the receiver can solve the equation to derive the missing data. The process of solving the equations is simple and linear, meaning it doesn't require much processing on behalf of the router/smartphone/laptop. In testing, the coded TCP resulted in some dramatic improvements. MIT found that campus WiFi (2% packet loss) jumped from 1Mbps to 16Mbps. On a fast-moving train (5% packet loss), the connection speed jumped from 0.5Mbps to 13.5Mbps. Moving forward, coded TCP is expected to have huge repercussions on the performance of LTE and WiFi networks — and the technology has already been commercially licensed to several hardware makers."

Hugh Pickens writes "Karen Kaplan reports in the LA Times that Craig Venter is making plans to send a DNA sequencer to Mars. Assuming there is DNA to be found on the Red Planet – a big assumption, to be sure – the sequencer will decode its DNA, beam it back to Earth, put those genetic instructions into a cell and then boot up a Martian life form in a biosecure lab. Venter's 'biological teleporter' (as he dubbed it) would dig under the surface for samples to sequence. If they find anything, 'it would take only 4.3 minutes to get the Martians back to Earth,' says Venter, founder of Celera Genomics and the Institute for Genomic Research (TIGR). 'Now we can rebuild the Martians in a P4 spacesuit lab.' It may sound far-fetched, but the notion of equipping a future Mars rover to sequence the DNA isn't so crazy, and Venter isn't the only one looking for Martian DNA. MIT research scientist Christopher Carr is part of a group that's 'building a a miniature RNA/DNA sequencer to search for life beyond Earth,' according to the MIT website 'The Search for Extra-Terrestrial Genomes.' SETG will test the hypothesis that life on Mars, if it exists, shares a common ancestor with life on Earth. Carr told Tech Review that one of the biggest challenges is shrinking Ion Torrent's 30-kilogram machine down to a mere 3 kg – light enough to fit on a Mars rover."

colinneagle writes "Several autonomous cars have been developed elsewhere, most famously by Google, and they are generally capable of identifying objects in the road directly ahead of or behind them. The challenge undertaken by MIT researchers is making these cars aware of dangers lurking around corners and behind buildings. MIT PhD student Swarun Kumar showed a video of a test run by the MIT researchers in which an autonomous golf cart running the technology, called CarSpeak (PDF), encountered a pedestrian walking from the entrance of a building to a crosswalk. The golf cart stopped roughly five yards ahead of the crosswalk and waited long enough for the pedestrian to walk to the other side of the road. The vehicle then continued driving automatically. The solution Kumar presented is based on a method of communications that is intended to expand the vehicle's field of view. This can be accomplished by compressing and sharing the data that autonomous vehicles generate while they're in motion, which Kumar says can amount to gigabits per second. In a comparison test, a car using CarSpeak's MAC-based communications was able to stop with a maximum average delay of 0.45 seconds, compared to the minimum average delay time of 2.14 seconds for a car running 802.11, the report noted."

bdking writes "A typeface family commonly found on the devices installed in many modern cars is more likely to cause drivers to spend more time looking away from the road than an alternative typeface tested in two studies, according to new research from MIT's AgeLab." It seems that the closed letter forms of Grotesque type faces require slightly more time to read than open letter forms of Humanist type faces, just enough that it could be problematic at highway speeds.

First time accepted submitter moon_unit2 writes "Technology Review has the scoop on a new industrial robot created by famed robotics researcher Rodney Brooks. The robot, Baxter, is completely safe, extremely adaptable, and ridiculously easy to program. By providing a way to automate simple manufacturing work, it could help make U.S. manufacturers compete with Chinese companies that rely on low-cost human labor. You can see the new robot in action in a related video of the robot in action and Brooks discussing its potential." $22 thousand and shipping next month, goes the story.

vu1986 writes with this bit from GigaOm: "Google has made public the details of its Spanner database technology, which allows a database to store data across multiple data centers, millions of machines and trillions of rows. But it's not just larger than the average database, Spanner also allows applications that use the database to dictate where specific data is stored so as to reduce latency when retrieving it. Making this whole concept work is what Google calls its True Time API, which combines an atomic clock and a GPS clock to timestamp data so it can then be synched across as many data centers and machines as needed." Original paper. The article focuses a lot of the Time API, but external consistency on a global scale seems to be the big deal here. From the paper: "Even though many projects happily use Bigtable, we have also consistently received complaints from users that Bigtable can be difficult to use for some kinds of applications: those that have complex, evolving schemas, or those that want strong consistency in the presence of wide-area replication. ... Many applications at Google have chosen to use Megastore (PDF) because of its semi-relational data model and support for synchronous replication, despite its relatively poor write throughput. As a consequence, Spanner has evolved from a Bigtable-like versioned key-value store into a temporal multi-version database. Data is stored in schematized semi-relational tables; data is versioned, and each version is automatically timestamped with its commit time; old versions of data are subject to configurable garbage-collection policies; and applications can read data at old timestamps. Spanner supports general-purpose transactions, and provides a SQL-based query language." Update: 09/20 17:57 GMT by T : Also in a story at Slash BI.

An anonymous reader writes with news of research from MIT, where engineers have found a better way to use ultrasound waves to boost the permeability of skin for the delivery of drugs. "Ultrasound — sound waves with frequencies greater than the upper limit of human hearing — can increase skin permeability by lightly wearing away the top layer of the skin, an effect that is transient and pain-free. ... When ultrasound waves travel through a fluid, they create tiny bubbles that move chaotically. Once the bubbles reach a certain size, they become unstable and implode. Surrounding fluid rushes into the empty space, generating high-speed 'microjets' of fluid that create microscopic abrasions on the skin. In this case, the fluid could be water or a liquid containing the drug to be delivered. In recent years, researchers working to enhance transdermal drug delivery have focused on low-frequency ultrasound, because the high-frequency waves don’t have enough energy to make the bubbles pop. However, those systems usually produce abrasions in scattered, random spots across the treated area. In the new study (abstract), the MIT team found that combining high and low frequencies offers better results. The high-frequency ultrasound waves generate additional bubbles, which are popped by the low-frequency waves."

hypnosec writes about a neat little hack using Lego, Raspberry Pis, and Scratch to construct a "supercomputer." From the article: "A team of computational engineers over at the University of Southampton led by Professor Simon Cox have built a supercomputer using Raspberry Pi and Lego. The supercomputer is comprised of 64 processors, 1TB of storage (16GB SD cards in each of the Raspberry Pis) and can be powered on using just a single 13-amp mains socket. MPI is used for communications between the nodes through the ethernet port. The team managed to build the core of the supercomputer for under £2500. Named 'Iridis-Pi' after University of Southampton's supercomputer Iridis, the supercomputer runs software that was built using Python and Scratch. Professor Cox used the free plug-in 'Python Tools for Visual Studio' to develop code for the Raspberry Pi." Lots of pictures of the thing, and a howto on making your own.

submeta writes "Researchers at MIT and the University of Pennsylvania have genetically engineered skeletal muscle cells to respond to light. The hope is that this 'bio-integrated' approach may lead to 'highly articulated, flexible robots.' The technique, known as optogenetics, has previously been used to stimulate neurons in worms to fire."

An anonymous reader writes "A research team led by Paulo Lozano at MIT's Space Propulsion Lab and Microsystems Technology Lab have shown off a microthruster array capable of powering small satellites. The tiny, flat design could obviate the need for bulky propellant tanks. 'To explain how the thruster works, Lozano invokes the analogy of a tree: Water from the ground is pulled up a tree through a succession of smaller and smaller pores, first in the roots, then up the trunk, and finally through the leaves, where sunshine evaporates the water as gas. Lozano's microthruster works by a similar capillary action: Each layer of metal contains smaller and smaller pores, which passively suck the ionic liquid up through the chip, to the tops of the metallic tips. The group engineered a gold-coated plate over the chip, then applied a voltage, generating an electric field between the plate and the thruster's tips. In response, beams of ions escaped the tips, creating a thrust. The researchers found that an array of 500 tips produces 50 micronewtons of force — an amount of thrust that, on Earth, could only support a small shred of paper. But in zero-gravity space, this tiny force would be enough to propel a two-pound satellite.'"

derekmead writes "Meshworm is a toughened, robotic earthworm that can crawl virtually silently at a speed of about 5 millimeters per second. DARPA wants to send it into battle. Believe it or not, the Pentagon's been working on building a robotic earthworm for a while. They tried putting one together with gears. They tried with air-powered and pneumatic pumps, but the results were bulky and untenable. Then, researchers at Harvard, MIT and Seoul National University in Korea put their heads together and designed an 'artificial muscle.' It's essentially a polymer mesh that's wrapped with nickel and titanium wire designed to stretch and contract with heat. When an electric current is applied, the mesh mimics the circular muscle system of an earthworm to scoot forward."

ananyo writes "With the Olympics due to kick off on 27 July in London, Nature has taken a look at how far science would be able to push human athletic abilities if all restrictions on doping were lifted. The article mentions anabolic steroids (up to 38% increase in strength), IGF-1 (4% increase in sprinting capacity), EPO/blood doping (34% increase in stamina), gene doping and various drugs and supplements, as well as more 'extreme' measures such as surgery and prosthesis. Hugh Herr, a biomechanical engineer at MIT, says performance-enhancing technologies will one day demand an Olympics all their own. But is that time already upon us?"

MrSeb writes "Engineers at the Massachusetts Institute of Technology (MIT) are busy working on a type of 3D display capable of presenting a 3D image without eye gear. What you've been presented with at your local cinema (with 3D glasses) or on your Nintendo 3DS console (with your naked eye) pales in comparison to what these guys and gals are trying to develop: a truly immersive 3D experience, not unlike a hologram, that changes perspective as you move around. The project is called High Rank 3D (HR3D). To begin with, HR3D involved a sandwich of two LCD displays, and advanced algorithms for generating top and bottom images that change with varying perspectives. With literally hundreds of perspectives needed to accommodate a moving viewer, maintaining a realistic 3D illusion would require a display with a 1,000Hz refresh rate. To get around this issue, the MIT team introduced a third LCD screen to the mix. This third layer brings the refresh rate requirement down to a much more manageable 360Hz — almost within range of commercially produced LCD panels."

An anonymous reader writes "MIT researchers have invented an algorithm which is able to amplify motion in video that is invisible to the naked eye — such as the motion of blood pulsing through a person's face, or the breathing of an infant. The algorithm — which was invented almost by accident — could find applications in safety, medicine, surveillance, and other areas. 'The system is somewhat akin to the equalizer in a stereo sound system, which boosts some frequencies and cuts others, except that the pertinent frequency is the frequency of color changes in a sequence of video frames, not the frequency of an audio signal. The prototype of the software allows the user to specify the frequency range of interest and the degree of amplification. The software works in real time and displays both the original video and the altered version of the video, with changes magnified.'"

astroengine writes "After collecting the vast quantities of data gathered by orbiting Mars spacecraft, MIT scientists have uncovered some rather interesting facts about Martian snow. For starters, as the majority of the Mars atmosphere is composed of carbon dioxide, the snowflakes are made from CO2 ice — basically tiny particles of 'dry ice.' Also, the snowflakes are very small — approximately the size of a red blood cell. 'These are very fine particles, not big flakes,' said MIT assistant professor Kerri Cahoy in a press release. If you saw these 'snowflakes' fall, 'you would probably see it as a fog, because they're so small,' she added."

retroworks writes "Bloomberg News makes the case that when the federal government offers tuition assistance, students apply to more expensive colleges, giving the institutions an incentive to raise tuition and a disincentive to lower it. (The Wall Street Journal has a similar article, but it's paywalled.) This reminds me of the debate over President Reagan's cuts to the Pell Grant program in the 1980s. MIT's Campus Paper 'The Tech' quoted the MIT administration as saying it had 'no idea what really will occur' when Reagan's proposal to cut Pell came to Washington. So the question is, 25 years later, do we know now? Did cuts to federal tuition assistance hurt the education of the lower income students? Did increases to Pell grants create more opportunity? Or is federal money the milkshake, and students are just the straw?"

MrSeb writes "Neuroengineers at MIT have created an implantable fuel cell that generates electricity from the glucose present in the cerebrospinal fluid that flows around your brain and spinal cord. The glucose-powered fuel cell is crafted out of silicon and platinum, using standard semiconductor fabrication processes. The platinum acts as a catalyst, stripping electrons from glucose molecules, similar to how aerobic animal cells (such as our own) strip electrons from glucose with enzymes and oxygen. The glucose fuel cell produces hundreds of microwatts (i.e. tenths of a milliwatt), which is a surprisingly large amount — it comparable to the solar cell on a calculator, for example. This should be more than enough power to drive complex computers — or perhaps more interestingly, trigger clusters of neurons in the brain. In theory, this glucose fuel cell will actually deprive your brain of some energy, though in practice you probably won't notice (or you might find yourself growing hungry sooner)."

MrSeb writes "MIT has devised a way of creating complex, self-assembling 3D nanostructures of wires and junctions. While self-assembling structures have been made from polymers before, this is the first time that multi-layer, configurable layouts have been created, opening up the path to self-assembled computer chips. Basically, MIT uses diblock copolymers, which are large molecules formed from two distinct polymers (each with different chemical and physical properties). These copolymers naturally form long cylinders — wires. The key to MIT's discovery is that the scientists have worked out how to exactly control the arrangement of these block copolymers. By growing tiny, 10nm-wide silica 'posts' on a silicon substrate, the researchers can control the angles, bends, spacing, and junctions of the copolymer wires. Once the grid of posts has been built, the wafer is simply covered in the polymer material, and chip's wires and junctions self-assemble. The reason everyone is so excited, though, is that the silica posts can be built using equipment that is compatible with existing semiconductor fabs. Theoretically, chips built using this technique could have a much smaller feature size than the 28nm and 22nm chips produced by TSMC and Intel. According to Caroline Ross of MIT, it should be possible to build posts that are much smaller than 10nm."

First time accepted submitter sarfralogy writes with this news about a cooler redesigned by MIT that is saving lives. "It started with a basic soft drink cooler, a need for easier management of tuberculosis and $150,000 in innovation support. A big challenge in managing tuberculosis is keeping the medicine cool, in addition to tracking and monitoring dose administration. These challenges can be life-threatening, especially in less-developed countries, where refrigerators and fancy cooling devices are rare; ice must be trucked in on a daily basis to keep medicines at controlled temperatures. A redesigned cooler with the ability to keep the medicine cool and record when medicine is dispensed is aiming to solve both these problems. The design of the cooler is simple and practical — common characteristics of a scientifically sound experiment or innovation. It's nothing more than a standard soft drink cooler but the team from MIT's Little Devices Lab equipped the cooler with the ability to sound an alert when the temperature inside the cooler becomes too high and transmit data wirelessly using a cellphone transmitter whenever the cooler is opened."

New submitter slashbill writes "MIT's working on a way to measure network capacity. Seems no one really knows how much data their network can handle. Makes you wonder about how then do you calculate expense when building out capacity? From the article: 'Recently, one of the most intriguing developments in information theory has been a different kind of coding, called network coding, in which the question is how to encode information in order to maximize the capacity of a network as a whole. For information theorists, it was natural to ask how these two types of coding might be combined: If you want to both minimize error and maximize capacity, which kind of coding do you apply where, and when do you do the decoding?'" This is a synopsis of the first of two papers on the topic.

JSBiff sends this quote from MITnews: "A new study from MIT scientists suggests that the guidelines governments use to determine when to evacuate people following a nuclear accident may be too conservative. The study (abstract), led by Bevin Engelward and Jacquelyn Yanch and published in the journal Environmental Health Perspectives, found that when mice were exposed to radiation doses about 400 times greater than background levels for five weeks, no DNA damage could be detected. Current U.S. regulations require that residents of any area that reaches radiation levels eight times higher than background should be evacuated. However, the financial and emotional cost of such relocation may not be worthwhile, the researchers say."

MrSeb writes "A group of American researchers from MIT, Indiana University, and Tufts University, led by Erin Treacy Solovey, have developed Brainput — a system that can detect when your brain is trying to multitask, and offload some of that workload to a computer. Using functional near-infrared spectroscopy (fNIRS), which is basically a portable, poor man's version of fMRI, Brainput measures the activity of your brain. This data is analyzed, and if Brainput detects that you're multitasking, the software kicks in and helps you out. In the case of the Brainput research paper (PDF), Solovey and her team set up a maze with two remotely controlled robots. The operator, equipped with fNIRS headgear, has to navigate both robots through the maze simultaneously, constantly switching back and forth between them. When Brainput detects that the driver is multitasking, it tells the robots to use their own sensors to help with navigation. Overall, with Brainput turned on, operator performance improved — and yet they didn't generally notice that the robots were partially autonomous. Moving forward, Solovey wants to investigate other cognitive states that can be reliably detected using fNIRS. Imagine a computer that increases the size of buttons and text when you're tired, or a video game that slows down when you're stressed. Your Xbox might detect that you're in the mood for fighting games, and change its splash screen accordingly. Eventually, computer interfaces might completely remold themselves to your mental state."

An anonymous reader writes "Launched in 1995, SSH quickly became the king of network login tools, supplanting the old insecure mainstays TELNET and RLOGIN. But 17 years later, a group of MIT hackers have come out with "mosh", which claims to modernize the most annoying parts of SSH. Mosh keeps its connection alive when clients roam among WiFi networks or switch to 3G, and gives instant feedback on typing (and deleting). No more annoying network lag on typing, the MIT boffins say, citing Bufferbloat, which has been increasing latencies." The folks involved have a pre-press research paper with the gritty details (to be presented at USENIX later this year). Mosh itself is not particularly exciting; the new State Synchronization Protocol it is based upon might be: "This is accomplished using a new protocol called the State Synchronization Protocol, for which Mosh is the first application. SSP runs over UDP, synchronizing the state of any object from one host to another. Datagrams are encrypted and authenticated using AES-128 in OCB mode. While SSP takes care of the networking protocol, it is the implementation of the object being synchronized that defines the ultimate semantics of the protocol."

An anonymous reader writes "Today, a typical chip might have six or eight cores, all communicating with each other over a single bundle of wires, called a bus. With a bus, only one pair of cores can talk at a time, which would be a serious limitation in chips with hundreds or even thousands of cores. Researchers at MIT say cores should instead communicate the same way computers hooked to the Internet do: by bundling the information they transmit into 'packets.' Each core would have its own router, which could send a packet down any of several paths, depending on the condition of the network as a whole."

In a posting to the Guile developers list today, it was announced that the Emacs-Lisp compiler for Guile has matured enough to run actual elisp programs. The author included a screencast demoing the new compiler running the Dunnet dungeon crawler. It is still a bit hackish: you need a load file that fakes a few Emacs side functions. In theory, most batch mode programs that don't do buffer manipulation should now work. After a few previous attempts, things could be on track for GNU Emacs 25 based on Guile.
