Simulating Supernovae with Graphics Cards
astroboy writes "As graphics cards get more powerful, Los Alamos and Utah scientists have developed a package, Scout, to use those usually-languishing FLOPs to do simulations, and to visualize of them on the on the run. As an example, they have released movie of part of the evolution of a core-collapse supernovae" -
SETI Disrupted By Cell Phones in Airplanes?
Iphtashu Fitz writes "If, as recently mentioned, the FCC does allow wireless access on airplanes, could it effectively mean the end of the search for ET? NewScientist has a new article that explains how radio interference from airborne cellphones could drown out faint radio signals from space. Among other concerns astronomers have is that the second harmonic of many cell phones falls in a frequency band that reveals the molecular signature of newborn and dying stars, which is among the 2% of frequencies in this part of the electromagnetic spectrum reserved for use by radio astronomers. Michael Davis, director of projects at California's SETI Institute, stated that a single cellphone on an airplane 100 miles from a radiotelescope could exceed recommended radio noise levels by 10 times. A potential solution that astronomers have suggested is to install a miniture cell transceiver on each airplane, called a picocell, that would act as a relay using a frequency that wouldn't interfere with their work." -
Effort to Create Virtual Brain Begins
bryan8m writes "An IBM supercomputer running on 22.8 teraflops of processing power will be involved in an effort to create the first computer simulation of the entire human brain. From the article: 'The hope is that the virtual brain will help shed light on some aspects of human cognition, such as perception, memory and perhaps even consciousness.' It should also help us understand brain malfunctions and 'observe the electrical code our brains use to represent the world.'" -
Perspecta Walk Around 3D Display
Spinneyhead writes "New Scientist reports on the Perspecta display, a goldfish bowl like device that displays moving images in such a way that they seem to "float" within the display. "To display the image, software inside the Perspecta chops a 3D model generated by the computer into 198 separate pieces, like slices of cake, which are then projected onto the screen in quick succession by a graphics accelerator that feeds image slices to an optical system mounted below the screen. The result looks to the viewer like a 3D image composed of 100 million "volume pixels" or "voxels"."" -
Earth Microbes May Survive On Mars
Vicissidude writes "New Scientist is reporting that terrestrial microbes who hitch a ride to Mars on spacecraft may be able to survive under special circumstances." From the article: "...Mars's thin atmosphere allows such intense ultraviolet radiation to reach the planet's surface - triple that found on Earth - that any life inadvertently carried on the spacecraft is thought to be wiped out quickly...However, the bacteria were able to stay alive if they were shielded by just 1 millimeter of soil during the tests, which ran for up to 24 hours. Under such a protective coating, the bacteria could survive - and potentially grow - under the high Martian UV flux if water and nutrient requirements for growth were met." -
New Way To Crack Secure Bluetooth Devices
moon_monkey writes "Cryptographers have discovered a way to hack Bluetooth-enabled devices even when security features are switched on, according to a report from New Scientist.com. The discovery may make it even easier for hackers to eavesdrop on conversations and charge their own calls to someone else's cellphone. From the article: 'Our attack makes it possible to crack every communication between two Bluetooth devices, and not only if it is the first communication between those devices,'" -
Bacterial Printing Press
juushin writes "New Scientist has reported that scientists at Harvard University have created a bacterial printing press that can be reconfigured to print complex patterns of bacteria. The technology is reported to have applications in studying biofilms, communication between bacteria (and colonies of bacteria), and the interaction of bacteria and surfaces. Of medical interest, these applications may lead to a better understanding of how to prevent bacterial infections." -
Self-wiring Supercomputer
redcone writes "New Scientist is reporting on an experimental supercomputer made from Field Programmable Gate Arrays (FPGA) that can reconfigure itself to tackle different software problems. It is being built by researchers in Scotland. The Edinburgh system will be up to 100 times more energy efficient than a conventional supercomputer of equivalent computing power. The 64-node FPGA machine will also need only as much space as four conventional PCs, while a normal 1 teraflop supercomputer would fill a room. Disclaimer: At this point in time, the software needed to run it, which is the key to the project, is vaporware. " -
Keep Fit Program For The Brain
merryprankster writes "New Scientist is running a feature on 11 steps to a better brain. While becoming a nun might be an extreme way to avoid senility, there are lots of other tricks, techniques and habits, as well as changes to your lifestyle, diet and behaviour that can help you flex your grey matter and get the best out of your brain cells." From the article: "First, go to the top of the class by eating breakfast. The brain is best fuelled by a steady supply of glucose, and many studies have shown that skipping breakfast reduces people's performance at school and at work. But it isn't simply a matter of getting some calories down. According to research published in 2003, kids breakfasting on fizzy drinks and sugary snacks performed at the level of an average 70-year-old in tests of memory and attention." -
Using Email Networks as P2P Spam Filters
Oscar Boykin writes "New Scientist is running a story on using the social network in email as a P2P network. The idea is that email networks have structure that is conducive to a type of search called percolation search . This means email clients could query the social network of email users to filter spam. This story is based on a preprint available." -

Fast Generation of 3D City Models
FleaPlus writes "New Scientist and UC Berkeley News report on research by Avideh Zakhor and Christian Früh on rapidly and automatically generating photo-realistic 3D models (coral cache) of city environments. This is reminiscent of research mentioned here in March, although the approach is rather different. Applications for areas like urban planning, entertainment, emergency response, and the military are discussed. Zakhor's group is also working on 4D systems, to allow for recording of events over time as moving 3D models." -
Vacuum-Controlled Elevator Developed
Aenox writes "Vacuum Elevators of Florida have released a one-man elevator system that easily slots into buildings. It has gone on sale in the U.S. for around $20,000 and uses only electricity to power vaccum-inducing suction turbines that can lift 204Kg several floors up. They claim it provides a smooth ride but from the video it looks like it could use some oil." -
Google to use TrustRank for News, Possibly More
mike slaven writes "In a follow-up to Tuesday's post about Google registering a trademark on the term TrustRank, an article on NewScientist explains how Google plans to track the credibility of news sources. The article also mentions that the patent on TrustRank is not limited to ranking just news stories: 'The patent also reveals that the same system could be roped in to rank other search results, not simply news. So sales and services could in the future be listed on the basis of price and the reputation of the company involved.'" -
Black Boxes for Spacecrafts
karvind writes "NewScientist is running story about NASA's plan to put small, heat-resistant black boxes that will transmit data back to Earth when future space probes break up during re-entry to the Earth's atmosphere. NASA will work with Aerospace Corporation to develop black boxes called Reentry Breakup Recorders (REBRs) weighing just 1 kilogram and spanning less than 30 centimetres." -
Minority Report UI For The Military
merryprankster writes "New Scientist is reporting that a 'Minority Report' style interface is being developed by defense company Raytheon. Users don a pair of reflective gloves and manipulate images projected on a panoramic screen. A mounted camera keeps track of hand movements and a computer interprets gestures. Raytheon has even employed John Underkoffler, the researcher who proposed the interface to the makers of the film. Now just wait till Billboards start scanning your iris." -
Commercial Exoskeletons
FalconZero writes "For those of you with superhuman aspirations, your dream may be a step closer; New Scientist (recently) and the Japan Times (last year) covered Yoshiyuki Sankai's work at the University of Tsukuba in Japan developing powered exoskeletons with commercial versions expected soon costing between $14,000 and $19,000 (£7,500-£10,000). Other work with exoskeletons previously covered here(1), here(2) and here(3)." -
Detecting Speech Without Microphones
kyle90 writes "New Scientist is reporting on a new way of detecting speech without using microphones, using electrodes places on the neck that measure muscle activity and nerve impulses. Apparently the user doesn't even need to speak the words out loud in order for them to be detected. This looks like pretty neat technology; if used with cell phones it could give the user a little more privacy, and the rest of us a little more peace and quiet." -
Precision Gene Editing
mpthompson writes "NewScientist.com is reporting that scientists at Sangamo Biosciences have developed a method of editing DNA mutations with unprecedented precision without weaving in potentially harmful foreign genetic material. Different combinations of amino acids are designed to latch on and cut the DNA at exactly the place where the mutated gene lies. This triggers the body's natural repair process which corrects the gene where the DNA was cut. The technique will be used to target diseases caused by single-gene mutations such as combined immune deficiency (X-SCID) - or bubble boy disease - and sickle cell anaemia." -
Top 10 Evolutionary Adaptations
oneill40 writes "The New Scientist has an interesting article up listing the Top 10 most amazing things to have evolved, including sex, death, the eye, language and parasites!" From the article:"Sponges are a key example of multicellular life, an innovation that transformed living things from solitary cells into fantastically complex bodies. It was such a great move, it evolved at least 16 different times. Animals, land plants, fungi and algae all joined in." J adds: Number four, Language, got a careful look from Carl Zimmer a while back. It's Pinker vs. Chomsky, winner take all, pass the popcorn! -
Sony Patents Matrix-Like Game Technology
howman writes "Reuters is reporting that Sony has been granted 2 patents, both describing 'Method and system for generating sensory data onto the human neural cortex'. These are patents 6,729,337 and 6,536,440. The patents go on to 'describe a technique for aiming ultrasonic pulses at specific areas of the brain to induce sensory experiences such as smells, sounds and images'. The story was first broken by New Scientist magazine." Commentary also available via Ars Technica. -
Patent Databases Complicate Life For Inventors
karvind writes "New Scientists is running a story about how the move to electronic record-keeping is making it harder to check if a device has already been invented. From the article: '.. even though most online patent archives are incomplete, parts of the paper-based collections that preceded them are being destroyed.' We ran a story earlier on how to fix U.S. patents. Maybe I can patent the wheel again." -
3 Electronic Maestros Interviewed
thesixthreplicant writes "New Scientist interviews 3 pioneers of electronic music: Bob Moog, the inventor of the first commercial synthesiser, the Moog; Australian Peter Vogel, creator of the first electronic sampler, the Fairlight (16 bit sampling in 1979!); and Dave Smith, the father of MIDI." -
Toshiba's One-Minute-Recharge Li-ion Batteries
TheGuano writes "No idea if this is related to Altair's six-minute-charge Li-ions,, but Toshiba has just announced a similar Li-ion that recharges to 80% capacity in one minute, while losing only 1% total capacity after 1000 cycles. It's set to debut in 2006 for use in hybrid cars (my current Toshiba Satellite doesn't get very far on battery power, but it's a beautiful shade of blue), but 'should' make its way to other, hopefully smaller devices eventually." -
Wily Octopi Walk on Two Arms
lousyd writes "Offering hope for new forms of ambulatory robots, biologist Christine L. Huffard, at UC Berkeley, has caught individual octopi sneaking away from predators by using two of their arms as legs. They use the other six arms to make themselves look like coconuts or algae. The research is being done as part of a project on robotics. This reminds me of the Far Side cartoon where the cows drop to all fours when humans come around, but resume standing on two legs otherwise." And I for one welcome our new mollusk overlords. -
Classic Math Puzzle Cracked
An anonymous reader writes "This is cool - if mind-bending. A century ago, a self-taught math genius from India noticed some patterns in how numbers can be created by adding other numbers. Now a grad student has finished the job showing that the patterns apply to all prime numbers, not just some. There's more on the Indian math guy here." -
13 Things That Do Not Make Sense
thpr writes "New Scientist is reporting on 13 things which do not make sense. It's an interesting article about 13 areas in which observations do not line up with current theory. From the placebo effect to dark matter, it's a list of areas in need of additional research. Explanations could lead to significant breakthroughs... or at least new and different errors in scientific observations. Now there are 20 interesting problems for Slashdotters to work on, once you combine these with the seven Millennium Problems!" -
Lab-Made Fireball May Be a Black Hole
MoogMan writes "BBC News reports that a lab fireball may be a black hole. From the article: "A fireball created in a US particle accelerator has the characteristics of a black hole, a physicist has said. The Brown researcher thinks the particles are disappearing into the fireball's core and reappearing as thermal radiation, just as matter falls into a black hole and comes out as "Hawking" radiation." More information available from the NewScientist article (subscription required)." -
Online Purchases Can Give You Away
Abhishek writes "New Scientist reports that Retailers could guess your age, sex, birthday and wedding anniversary simply from the types of gifts purchased for you online and their timing, according to a patent granted to online retail giant, Amazon. The information could be used to remind your loved ones of an impending special occasion and offer gift suggestions. Currently Amazon makes personalised suggestions to customers based on previous purchases by that customer, previous web pages browsed and comparisons between customers who have bought similar products. But the company may vastly increase its predictive capability in the future." -
Automatic 3D Reconstruction of Scenes
Neil Halelamien writes "New Scientist reports on a piece of software by MDRobotics called instant Scene modeler (iSM), which automatically generates 3D reconstructions of scenes, using a few hundred frames from a pair of ordinary video cameras. The software uses David Lowe's SIFT vision algorithm to quickly locate common features between sequential images, for use in the reconstruction; SIFT has also been useful for generating panoramas and object recognition. MDRobotics has a demo page showing the software being used for crime scene reconstruction, along with animated GIFs of input video and the resulting 3D model." -
Arm Wrestling Robots Beaten By A Teenage Girl
fembots writes "Despite her lack of strength, training and technique, a 17-year-old girl has bested three robot arm wrestlers in a contest attempted to encourage the development of polymer-based artificial muscles, which can change shape when activated either electrically or with chemicals." -
Mars Rovers Have Incorrect Instruments Installed
Christopher Reimer writes "The New Scientist is reporting that the twin Mars rovers, Opportunity and Spirit, has instruments installed in the wrong rovers. From the article: 'While the bungle does not undermine the main scientific conclusions drawn from the data collected by the rovers, it is an embarrassing slip-up for a space agency that once lost a Mars spacecraft because engineers mixed up metric and imperial units.'" -
Translation Software That Learns by Reading
redcone writes "New Scientist is reporting that translation software that develops an understanding of languages by scanning through thousands of previously translated documents has been released by U.S. researchers. According to the article "The translated documents used to teach the translation algorithms can be electronic, on paper, or even audio files. The system is not only faster than other methods, but also better suited to tackling less common languages and the unusual vocabulary found in specialised or technical texts."" -
Martian Sea Discovered
mpesce writes "New Scientist is reporting that a large sea of frozen ice (between 800 and 900 km in size and 45 m deep) has been discovered by the ESA's Mars Express Probe. Here's the kicker: the sea of block ice is only five degrees away from the Martian equator. New Scientist also links to a PDF of a paper to be presented next month about the finding." Update: 02/21 15:30 GMT by T : Note: that's 45 meters deep, not 45 kilometers deep. -
Can India Become A Knowledge Superpower?
krsmathews writes " New Scientist, in its latest issue, has a special report on India. It provocatively calls India the next knowledge superpower, though in a introductory story the caveats are laid out. It's a reasonably comprehensive look at India's high-tech research, pharma, bio-tech, space, and nuclear industries. The U.S. R&D expenditure is bigger than the next five countries put together, and India is nowhere in the picture. " -

Personal Spaceflight Leaders Form New Federation
Neil Halelamien writes "A number of entrepreneurs in the nascent commercial space industry are establishing the Personal Spaceflight Federation, an industry group which will work with federal regulators to come up with standards to promote crew and passenger safety. The founders include both suborbital and orbital spaceflight entrepreneurs, such as Armadillo Aerospace's John Carmack, Scaled Composites's Burt Rutan, SpaceX's Elon Musk, and t/Space's Gary Hudson. Commentary available on MSNBC, Space.com, and Space Race News. In related news, NASA is looking at commercial options for resupply of the International Space Station." -
Coral Reefs Create Clouds to Control the Climate
Neil Halelamien writes "New Scientist reports on research showing that coral reefs might cool off by creating their own clouds. The scientists showed that coral reefs are packed with a chemical called DMS, which helps clouds to form when it is released into the atmosphere. In experiments, the researchers have shown that 'corals produce more DMS when the symbiotic algae inside their tissues become stressed by high temperatures or UV radiation,' suggesting that this may be a mechanism corals evolved to help regulate their environment." -
Competition to Build the Space Shuttle's Successor
Neil Halelamien writes "The competition for the prime contract to build the Crew Exploration Vehicle, the successor to the Space Shuttle, is ramping up. Currently, 11 different companies are creating preliminary designs for systems and vehicles which could be useful in implementing NASA's Vision for Space Exploration. By the end of the year, NASA will select two teams to independently develop and build a CEV design. The two teams will launch competing unmanned prototypes in 2008, at which point NASA will award a final winning contract. Aerospace giants Boeing and Northrop Grumman have formed one team. Another "all-star" team, announced a couple of days ago, is headed by Lockheed Martin. A third team in the running is underdog t/Space, a company with a free enterprise approach to space exploration, which includes notable figures from the commercial spaceflight arena, such as Burt Rutan and Gary Hudson. There is concern that a NASA budget boost to help pay for the exploration program could draw some opposition, as most other government programs are anticipating budget cuts." -
Solar Super-Sail Could Reach Mars in a Month

Deriving Semantic Meaning From Google Results
prostoalex writes "New Scientist talks about Paul Vitanyi and Rudi Cilibrasi of the National Institute for Mathematics and Computer Science in Amsterdam and their work to extract meaning of words from Google's index. The pair demonstrates an unsupervised clustering algorithm, which 'distinguish between colours, numbers, different religions and Dutch painters based on the number of hits they return', according to New Scientist." -
Disc Writers Now Print the Label Too

Sun Releases Largest Radiation Storm in 15 Years
what_the_frell writes "Newscientist is reporting that a large cluster of sunspots has just released huge amounts of radiation toward Earth. The crew of the ISS reportedly had to move into the bulkier Russian section of the station, while airlines rerouted planes away from the most affected regions. Look forward to varying degrees of radio & cell phone reception and some pretty cool aurora boreali until January 22, when the sunspot storm turns away from the earth, pointing its radiation elsewhere." -
World's Shortest P2P App: 15 Lines
soren.harward writes "The New Scientist has an article about TinyP2P, the world's smallest P2P app. It's 15 lines of Python code brought to us by Edward Felten, CS Professor at Princeton and outspoken supporter of the digital rights the Slashdot community holds so dear. He wrote the program as a proof-of-concept that P2P apps are really easy to write, don't have to be complicated, and thus banning them (a la the INDUCE Act) is pointless and silly."
