eldavojohn writes "The electronic voting machine has soured another election. Some French voters have reportedly turned away in disgust after facing up to two hours in lines to use the machines. Further, the article reports, 'Researchers at Paul Verlaine University in Metz said that trials on two of the three machines used in France showed that four people out of every seven aged over 65 could not get their votes recorded.' This article concentrates primarily on usability and efficiency, but surprisingly mentions little (aside from user trust issues) about the security embodied in the machines or whether it was satisfactory. I think all three aspects are important to anyone aiming to produce voting machines. The manufacturer of these particular machines is France Élection."

eldavojohn writes "The shots you take in CONE Sutro Forest don't come from shotguns or sniper rifles. In the game, players manipulate remote control cameras, taking pictures of birds and classifying them. It starts next week with the premise being that the more birds you take pictures of and classify correctly, the more points you get. It's more of an experiment in collaborative technology than a game ... but if you can get your users to do work for you and have fun at the same time, you might have something big."

eldavojohn writes "PhysOrg is covering an interesting year-old paper that proposes an alternative six-dimensional theory of space and time. George Sparling's proposition, based on Einstein's general relativity and Elie Cartan's triality, is a twistor space (which I've only read of in Roger Penrose's latest work). The gist is that space-time is modeled not by four dimensions but by six, and that the extra two dimensions are time-like. Sparling is hoping that tests from the Large Hadron Collider will help prove his theory. The paper is heavy but the PhysOrg article summarizes it nicely."

eldavojohn writes "In my browser, I regularly go to the tools menu and clear my private data. This includes my cookies. As a result, people like me who destroy cookies by the thousands may be inflating estimates of Web traffic by up to 150 percent. People have good reasons for clearing out cookies — we've heard about bad cookies before (and I think the FCC is still investigating the issue). But every time you delete cookies, many of the sites you've visited count you as a new visitor next time."

eldavojohn writes "Researchers at UCLA Henry Samueli School of Engineering and Applied Science managed to push our control of frequencies to another level when they hit a submillimeter 324 gigahertz frequency. As any signal geek out there might tell you, this is a non-trivial task. 'With traditional 90-nanometer CMOS circuit approaches, it is virtually impossible to generate usable submillimeter signals with a frequency higher than about 190 GHz. That's because conventional oscillator circuits are nonlinear systems in which increases in frequency are accompanied by a corresponding loss in gain or efficiency and an increase in noise, making them unsuitable for practical applications.' The article also talks about the surprising applications this new technology may evolve into."

forgethistory sends us to PhysOrg for a summary of new research suggesting that the near instantaneous energy transfer achieved by photosynthesis may rely on quantum effects. From the article: "Through photosynthesis, green plants and cyanobacteria are able to transfer sunlight energy to molecular reaction centers for conversion into chemical energy with nearly 100-percent efficiency. Speed is the key — the transfer of the solar energy takes place almost instantaneously so little energy is wasted as heat. How photosynthesis achieves this near instantaneous energy transfer is a long-standing mystery that may have finally been solved."

David Kesmodel from WSJ writes to let us know about an IBM breakthrough: a practical three-dimensional semiconductor chip that can be stacked on top of another electronic device in a vertical configuration. Chip makers have worked for years to develop ways to connect one type of chip to another vertically to reduce size and power use. The IBM technique of "through-silicon vias" offers a thousand-fold reduction in connector length and a hundred-fold increase in connector density. The new chips may appear in cellphones and other communication devices as soon as next year. PhysOrg has more details.

Andreaskem writes "A Carnegie Mellon University computer scientist says transferring large data files, such as movies and music, over the Internet could be sped up significantly if peer-to-peer (P2P) file-sharing services were configured to share not only identical files, but also similar files. "SET speeds up data transfers by simultaneously downloading different chunks of a desired data file from multiple sources, rather than downloading an entire file from one slow source. Even then, downloads can be slow because these networks can't find enough sources to use all of a receiver's download bandwidth. That's why SET takes the additional step of identifying files that are similar to the desired file... No one knows the degree of similarity between data files stored in computers around the world, but analyses suggest the types of files most commonly shared are likely to contain a number of similar elements. Many music files, for instance, may differ only in the artist-and-title headers, but are otherwise 99 percent similar.""

eldavojohn writes "Recently, the city government of Tokyo has requested that political speeches to be pulled from YouTube, claiming that it gave certain hopefuls an advantage over others for Sunday's election. You may recall YouTube being in trouble with more than a few countries in the past. 'Japanese election law limits the broadcasting of speeches, which are aired only on public broadcaster NHK. Soon after the race kicked off last month, the speech by one fringe candidate, street musician Koichi Toyama, 36, has become a popular attraction on YouTube due to his eccentric, confrontational approach.' Is it fair that some government officials are being viewed more on YouTube than others or is it simply leveling the playing field for anyone with a message since it costs very little to put a video on YouTube?"

eldavojohn writes "I've heard a lot of talk about software being used to detect pirated media anywhere on the web, but haven't seen a lot of details. PhysOrg has a good article on one of the tools out there. Automatic Copyright Infringement Detection (ACID) boasts a patented technology dubbed 'meaning-based computing' that is reportedly capable of finding relationships among 1,000 different types of files. The important thing is that this is not tagging-based searching. 'Autonomy's search technology uses automatic hyperlinking and link clustering that the company claims isn't built into keyword search engines. According to the company, this technology allows computers to perform searches with greater context, so it finds a wider range of related documents or research citations than is possible from keyword searches.' For more details on how this magic works, check out Autonomy's patent and the many patents by its subdivision, Virage."

eldavojohn writes "A non-profit alumni group from the University of Wisconsin (WARF) has suffered a preliminary ruling against three of their recent patents regarding stem cells. Given that these patents have been upheld in prior rulings, there is a lot of speculation that they will be upheld in a future court case. From the PhysOrg article: 'The patents, which cover virtually all stem cell research in the country, have brought in at least $3.2 million and could net much more money before they expire in 2015, the newspaper said. Companies wanting to study the cells must buy licenses costing $75,000 to $400,000. The newspaper said WARF recently started waiving the fees if the research is conducted at universities or by non-profit groups.' Should universities (or groups within universities) be allowed to hold patents and intellectual property while at the same time gaining donations and grants as an educational institution — or for that matter government funds?"

eldavojohn writes "Dust off your fundamental physics books, an aspiring astrophysicist by the name of Alex Ignatiev has published a paper that proposes testing special cases of Newton's Second Law on earth's surface. His goal is sort of ambitious. The time he has to test his theory is only 1/1000th of a second, twice each year, in either Greenland or Antarctica. What would he look for? Spontaneous motion. From his interview with PhysOrg: 'If these experiments were to take place, Ignatiev says that scientists would look for what he calls the SHLEM effect. This acronym stands for static high latitude equinox modified inertia and would be noticed in a condition where the forces of the earth's rotation on its axis, and of the orbital force of the earth as it moves around the sun, would be canceled out ... In the end, if Newton's Second Law could be violated, he would be forcing physicists to reevaluate much of what we understand derived from that law — which is quite a bit.'"

eldavojohn writes "After yet another contentious vote on the .xxx concept, ICANN has finally rejected the pornography TLD. The debate has gone on for quite some time, and the 9-5 decision was the third time a decision was reached on the subject. This is the second time the body has ruled against the idea, and is likely the last time we'll see it come up for vote any time soon. One member abstained from voting. From the article: 'Many of the board members said they were concerned about the possibility that ICANN could find itself in the content regulation business if the domain name was approved. Others criticized that, saying ICANN should not block new domains over fears like that, noting that local, state and national laws could be used to decide what is pornographic and what is not. Other board members said they believed that opposition to the domain by the adult industry, including Web masters, content providers and others, was proof that the issue was divisive and that .xxx was not a welcome domain.'"

sporkme writes "A new nanocoating material developed by a team of researchers from Rensselaer Polytechnic Institute has the lowest level of reflectivity ever seen ... or not seen in this case. The amount of light reflected by the composite of silica nanorods and aluminum nitride is almost the same amount reflected by air. From the article: 'Schubert and his coworkers have created a material with a refractive index of 1.05, which is extremely close to the refractive index of air and the lowest ever reported. Window glass, for comparison, has a refractive index of about 1.45. Using a technique called oblique angle deposition, the researchers deposited silica nanorods at an angle of precisely 45 degrees on top of a thin film of aluminum nitride, which is a semiconducting material used in advanced light-emitting diodes (LEDs). From the side, the films look much like the cross section of a piece of lawn turf with the blades slightly flattened.' Suggested applications include increased efficiency in solar cells, more energy-efficient lighting and advances in quantum mechanics."

ZonkerWilliam writes "Plasma wake particle accelerators are making surprisingly quick advances. It was a just a little while ago we had GeV acceleration in 3cm. Now they are capable of doubling the energy of electrons. 'Imagine a car that accelerates from zero to sixty in 250 feet, and then rockets to 120 miles per hour in just one more inch. That's essentially what a collaboration of accelerator physicists has accomplished, using electrons for their race cars and plasma for the afterburners. Because electrons already travel at near light's speed in an accelerator, the physicists actually doubled the energy of the electrons, not their speed.'"

chris-chittleborough writes "The Wall Street Journal reports that 'a Marine officer in Iraq, a small network-design company in California, a nonprofit troop-support group, a blogger and other undeterrable folk designed a handheld insurgent-identification device, built it, shipped it and deployed it in [Iraq] in 30 days.' Compare this to the Automated Biometric Identification System, a multi-megabuck Pentagon project now 2 years old. With bureaucracy increasingly strangling innovation, will agile smaller businesses be able to accomplish what once required a sprawling government project?"

ZonkerWilliam writes "It seems, at least theoretically, that there may be 'ocean planets' out there in the galaxy. If there are, we are closer than ever to detecting them. The formation of such planets is fairly likely, reports the PhysOrg article, despite the lack of an obvious example in our own solar system. We may have a former ocean planetoid in the neighborhood, orbiting the planet Jupiter: the moon Europa. These water worlds are the result of system formation castoffs, gas giant wannabes that never grew large enough. If any of these intriguing object exist nearby, the recently launched CoRoT satellite will be the device we use to see it. The article explains some of the science behind 'ocean worlds', as well as the new technology we'll use to find them."

deadmantyping writes "A Japanese research group published a paper describing a method to detect explosives in luggage using radio waves. The method relies upon nitrogen nuclear quadrapole resonance (NQR) and is able to distinguish between different white powders, whereas currently used x-ray technology is not."

Andreaskem submitted this story about researchers being able to encode an image into a photon and to later retrieve it intact. From the article: "It's analogous to the difference between snapping a picture with a single pixel and doing it with a camera — this is like a 6-megapixel camera... You can have a tremendous amount of information in a pulse of light, but normally if you try to buffer it, you can lose much of that information... We're showing it's possible to pull out an enormous amount of information with an extremely high signal-to-noise ratio even with very low light levels."

Mr. McGibby writes "Astronomers have come up with an improved method of looking for extraterrestrial life with an Earth-like civilization. Theorist Avi Loeb proposes to use instruments like the Low Frequency Demonstrator (LFD) of the Mileura Wide-Field Array (MWA), an Australian facility for radio astronomy currently under construction. The array could (theoretically) detect civilizations broadcasting in the same frequencies as our own society. From the article: 'Loeb and Zaldarriaga calculate that by staring at the sky for a month, the MWA-LFD could detect Earth-like radio signals from a distance of up to 30 light-years, which would encompass approximately 1,000 stars. More powerful broadcasts could be detected to even greater distances. Future observatories like the Square Kilometer Array could detect Earth-like broadcasts from 10 times farther away, which would encompass 100 million stars. ' The original paper describes the details."

eldavojohn writes "It may be no surprise but Wikipedia is now being used in the field of artificial intelligence. The applications for this may be endless. For instance, the front of spam fighting is a tough one and it looks as though researchers are now turning towards an ontology or taxonomy based solution to fight spammers. The concept is also on the forefront of artificial intelligence and progress towards an application passing the Turing Test and creating semantically aware applications. The article comments on uses of Wikipedia in this manner: '"... spam filters block all messages containing the word 'vitamin,' but fail to block messages containing the word B12. If the program never saw B12 before, it's just a word without any meaning. But you would know it's a vitamin," Markovitch said. "With our methodology, however, the computer will use its Wikipedia-based knowledge base to infer that 'B12' is strongly associated with the concept of vitamins, and will correctly identify the message as spam," he added.'"

srizah writes "Toyota is developing an Alcohol Detection System that can detect drunken drivers and would immobilize the car when it detects excessive alcohol consumption. From the article: 'Cars fitted with the detection system will not start if sweat sensors in the driving wheel detect high levels of alcohol in the driver's bloodstream, according to a report carried by the mass-circulation daily, Asahi Shimbun. The system could also kick in if the sensors detect abnormal steering, or if a special camera shows that the driver's pupils are not in focus. The car is then slowed to a halt, the report said.'"

An anonymous reader pointed us at a post on the Physorg blog, which discusses the possibility of an upcoming period of intense solar weather. We've discussed this before, but increasingly the evidence looks like 'Solar Cycle 24' (due to start in 2010 or so) is going to make life interesting here on earth. From the post: "Hathaway explains: 'When a gust of solar wind hits Earth's magnetic field, the impact causes the magnetic field to shake. If it shakes hard enough, we call it a geomagnetic storm.' In the extreme, these storms cause power outages and make compass needles swing in the wrong direction. Auroras are a beautiful side-effect. Hathaway and Wilson looked at records of geomagnetic activity stretching back almost 150 years and noticed something useful:. 'The amount of geomagnetic activity now tells us what the solar cycle is going to be like 6 to 8 years in the future,' says Hathaway."

anaesthetica writes "Physorg.com is featuring a story asserting that hydrogen is economically infeasible as a replacement for our current energy sources. The premise is that isolating and converting hydrogen into a usable energy source takes up a great deal of energy to begin with, and that subsequently converting that hydrogen fuel into usable energy results in an overall efficiency of only about 25%. Apparently, the increasing scarcity of water is going to make hydrogen too costly and just as politicized as oil." From the article: "[Fuel cell expert Ulf Bossel's] overall energy analysis of a hydrogen economy demonstrates that high energy losses inevitably resulting from the laws of physics mean that a hydrogen economy will never make sense. The advantages of hydrogen praised by journalists (non-toxic, burns to water, abundance of hydrogen in the Universe, etc.) are misleading, because the production of hydrogen depends on the availability of energy and water, both of which are increasingly rare and may become political issues, as much as oil and natural gas are today."

ZonkerWilliam writes to mention PhysOrg is reporting that a tiny particle with no charge, called an 'axion' has been discovered. From the article: "The finding caps nearly three decades of research both by Piyare Jain, Ph.D., UB professor emeritus in the Department of Physics and lead investigator on the research, who works independently -- an anomaly in the field -- and by large groups of well-funded physicists who have, for three decades, unsuccessfully sought the recreation and detection of axions in the laboratory, using high-energy particle accelerators."

eldavojohn writes "Physorg is running an interesting article on the most recent of Hubble's accomplishments. It has provided us evidence supporting that which Emmanuel Kant proposed over 200 years ago — that planets do indeed form from disks of gas and dust that surround stars. The trick, apparently, was observing many cases where a star's planet forms on the exact same circumstellar disk as the dust and gas. Hubble also aided the researchers in determining the weight of many extrasolar planets. Some had contended that these were not planets but rather brown dwarf stars — which is determined by measuring their weight." Update: 10/12 23:08 GMT by T : That's not the only theory Hubble's recent observation's have supported: read on below for a bit more. somegeekynick writes "Hubble has spotted a bunch of little galaxies, nicknamed Spiderweb, over 10 billion light-years away in the process of merging. This observation supports the so-called 'bottom-up' theory of galaxy formation, according to which smaller clumps of matter collided and merged with each other to form larger galaxies during early stages of the universe's evolution."

Paul Cobbaut writes "From Physorg: Philips Research intends to impress the visitors at this year's IFA (Internationale Funkausstellung) with a world-first demonstration of promotional jackets and furniture featuring its innovative Lumalive technology. Lumalive textiles make it possible to create fabrics that carry dynamic advertisements, graphics and constantly changing color surfaces. Here is the Philips Press Release." Obviously, all Devo videos will need to be reshot using this valuabe new technology advance.

luckyguesser writes to tell us that Physicists at the University of Bonn are claiming to have knocked down one more quantum computing hurdle. Utilizing what they term "laser tweezers" they were able to sort and align seven atoms while capturing it on film. The plan is to construct a quantum gate using atoms imprinted with data.

The New Revelation writes "Physorg reports that engineers at UBC have developed a single occupancy vehicle that achieves a ridiculous 3145 MPG! From the article: 'The Society of Automotive Engineers (SAE) Supermileage Competition took place June 9 in Marshall, Michigan. Forty teams from Canada, the U.S. and India competed in designing and building the most fuel-efficient vehicle... The UBC design, which required the driver to lie down while navigating it, achieved 3,145 miles per US gallon (0.074 liters/100 km) -- equivalent of Vancouver to Halifax on a gallon (3.79 liters) of gas -- costing less than $5 at the pump.'"

An anonymous reader writes "Scientists are claiming to have a new type of optical security that doesn't require embedment. Optical security includes many different options but up until now they have all required that the secret image be embedded in a host image which left it vulnerable. From the article: 'To address this problem of finding the secret image in the watermark, scientists have developed a new optical security method that doesn't require embedment. Instead, the technique uses a phase retrieval algorithm to generate specific optical and phase keys that extract the secret information when applied. The optical keys contain information and are distributed to an individual through a personal identification number (PIN). The information contained in the phase keys (the main source for determining extraction) is distributed to the individual separately.'"

patiwat writes "Recalling Ghost in the Shell, scientists at the Max Planck Institute for Biochemistry in Martinsried have coupled living brain tissue to a semiconductor chip. This technique involves culturing razor-thin slices of the hippocampus region on the chip, enabling them to record neural communication between thousands of nerve cells in the brain tissue slice. The hippocampus is associated with temporary storage of memory. Employing the new technique, the scientists working under the direction of Peter Fromherz were able to visualize the influence of pharmaceutical compounds on the neural network, making the 'brainchip' an exciting test bed for neuropharmaceutical research, with potential for further development in neurochip prosthetics and neurocomputation. The researchers reported this news in the online edition of the Journal of Neurophysiology (May 10, 2006)."

Krishna Dagli writes "China has launched a case against American chipmaker Intel's near-monopoly on encryption standards for wireless local area network (WLAN) equipment, state press reported Monday."

Mikki writes "Using methods employed in criminal investigations, the Japan Acoustic Lab has analyzed the skeletal structures of Leonardo Da Vinci and Mona Lisa's faces to replicate how their voices would have sounded." While Da Vinci is cool, I can think of a slew of other deceased notables worth talking with as well.

Santosh Maharshi wrote to mention a Physorg story about a new way to model social networks. From the article: "Applying a mathematical model to the social dynamics of people presents difficulties not involved with more physical - and perhaps more rational - applications. The many factors that influence an individual's fate to meet an acquaintance and decide to become a friend are impossible to capture, but physicists have used techniques from physical systems to model social networks with near precision. By modeling people's interactions based on how particles bounce off each other in an enclosed area, physicists Marta Gonzalez, Pedro Lind and Hans Herrmann found that the characteristics of social networks emerge 'in a very natural way.'"

inexion wrote to mention a story on PhysOrg stating that we're all doomed. "A space rock capable of sub-continent scale devastation has about a one in 1,000 risk of colliding with Earth early next century, the highest of any known asteroid, watchers said on Thursday. The rock, 2004 VD17, is about 500 metres (yards) long and has a mass of nearly a billion tonnes, which -- if it were to impact -- would deliver 10,000 megatonnes of energy, equivalent to all the world's nuclear weapons. Spotted on November 27 2004, VD 17 was swiftly identified as rock that potentially crossed Earth's orbit, with a 1 in 3,000 risk of collision on May 4 2102."

An anonymous reader writes "According to Physorg eavesdropping on a quantum encrypted link can now be done without detection. From the article: 'The scientists have succeeded in making the first remote copies of beams of laser light, by combining quantum cloning with quantum teleportation into a single experimental step. Telecloning is more efficient than any combination of teleportation and local cloning because it relies on a new form of quantum entanglement - multipartite entanglement.' There is also a PDF of a related paper available here for background material."

DrStrabismus writes "PhysOrg has a story about research that may indicate that close to light speed travel is possible. From the article: 'New antigravity solution will enable space travel near speed of light by the end of this century, he predicts. On Tuesday, Feb. 14, noted physicist Dr. Franklin Felber will present his new exact solution of Einstein's 90-year-old gravitational field equation to the Space Technology and Applications International Forum (STAIF) in Albuquerque. The solution is the first that accounts for masses moving near the speed of light.'"

inexion writes "PhyOrg is reporting that SLAC (Stanford Linear Accelerator Center) scientists have found a way to test the revolutionary theory, which posits that there are 10 or 11 dimensions in our universe. This past December, Joanne Hewett, Thomas Rizzo, and student Ben Lillie published an article in Physical Review Letters which shows theoretically how to measure the number of dimensions that comprise the universe. By determining how many dimensions exist, Hewett and Rizzo hope to either confirm or repudiate string theory under specific conditions which would consist of creating and examining 'micro-black holes', which could be formed by smashing two high energy protons together. Using the predicted decay properties of the emitted neutrinos, Hewett and Rizzo solved equations to find that our universe may have more than 10 or 11 dimensions -- too many dimensions to be explained by string theory."

Izeickl writes "PhysOrg.com is reporting that scientists working at a neutrino detector nicknamed AMANDA at the South Pole report that evidence for string theory may soon be coming. Extra dimensions predicted by string theory may affect observed numbers of certain neutrinos and this is what the scientists will be looking for. The article further states 'No more than a dozen high-energy neutrinos have been detected so far. However, the current detection rate and energy range indicate that AMANDA's larger successor, called IceCube, now under construction, could provide the first evidence for string theory and other theories that attempt to build upon our current understanding of the universe.'"

Dr Cool writes "A new design of spacecraft ion engine has been tested by the European Space Agency which dramatically improves performance over present thrusters and marks a major step forward in space propulsion capability. Ion engines are a form of electric propulsion and work by accelerating a beam of positively charged particles (or ions) away from the spacecraft using an electric field. ESA is currently using electric propulsion on its Moon mission, SMART-1. The new engine is over ten times more fuel efficient than the one used on SMART-1."

CelticCoder writes "With wide implications in the fight against global warming, Phyorg.com is reporting that plants naturally produce methane. Since methane is twenty times more potent than carbon dioxide in trapping heat, are efforts to fight global warming by planting forests actually harming the environment?"

Darkman, Walkin Dude wrote to mention a plucky little radiation-proof robot working to make life easier for folks in the military. From the article: "By this time an hour and a half had gone by, and the team was temporarily out of ideas. Phil had estimated that the robot could remain ambulatory in the radiation field for only 50 minutes, and in fact the robot's lower portion was no longer responding to commands. The RAP team, as a precaution against this very circumstance, working with White Sands personnel had tied a rope to M2 before sending it into the work area. The rope, attached to a RAP team winch 100 feet outside the structure, ensured the robot could be hauled out if radiation damaged its drive unit. But radiation shields now blocked a direct haul. M2 was hemmed in. Using a ten-foot-long pole and standing at the edge of the field (which fanned out like a flashlight beam, strongest at its center and weakest at its edges), team members hooked and then tugged at the rope hauling M2. The deflection of the rope's pull slid the robot around a moveable radiation shield without knocking it over. The RAP team's winch then pulled the robot directly out. "

linumax wrote to mention an article detailing an ambitious Japanese-led voyage towards the center of the earth. From the article: "The deep-sea drilling vessel Chikyu made a port call Thursday in Yokohama after ending its first training mission at sea since being built in July at a cost of 500 million dollars. The 57,500-ton Chikyu, which means the Earth in Japanese, is scheduled to embark in September 2007 on a voyage to collect the first samples of the Earth's mantle in human history. The project, led by Japan and the United States with the participation of China and the European Union, seeks clues on primitive organisms that were the forerunners of life and on the tectonic plates that shake the planet's foundations" They also hope to use the information to detect earthquakes more accurately. A 4 page PDF presentation about the Chikyu deep-sea drilling vessel is also available."

Ant writes "MSN Encarta has Columnist Martha Brockenbrough's article on the myths of this American holiday. From the article: 'A lot of what we know to be true about Thanksgiving really isn't. Determining exactly what did happen is difficult. For starters, we don't even know for certain if the Pilgrims served turkey, although it's a strong possibility.'" Additionally, maotx writes "Contrary to popular belief, turkey does not make you sleepy. While purified tryptophan is a mild sleep-inducing agent, there is not enough in turkey to have a sedative affect. And on top of that, turkey isn't even unusually high in tryptophan compared to other foods, such as beef or soybeans. So for those of us enjoying turkey today, bring on the turkey and have a Happy Thanksgiving!"

tkjtkj writes "Physorg.com is reporting that a Rochester,NY, company, 'Thermal Gradients, Inc' has produced a new method of DNA analysis that can reduce the required time from hours to minutes that the usual 'Polymerase Chain Reacion' (PCR) takes to produce the large quantity of sample DNA needed to identify the donor. This could,conceivably, make "Instant DNA Identification" a reality! Will air travel now require one to arrive at the airport 5 minutes earlier than usual, to provide a skin-swab sample before boarding the plane?"

neutron_p writes "IBM has recently announced a new and affordable 3D video system that works with normal DLP (Digital Light Processing) televisions. IBM demonstrated the new system on a 50-inch, flat-screen Texas Instruments rear-projection digital television at the 22nd annual Flat Information Displays conference held in San Francisco this month. This "black box" device can be connected to any DLP projector or television via the common VESA 3 pin stereo connector. Exact details concerning the 3D technology - still unnamed - were not forthcoming, but the company spokesperson said it was compatible with OpenGL and Direct Draw, which is definitely aimed at software developers who make 3D games."

coolphysco1010 wrote to discuss the possible development of a direct neural interface, ala 'The Matrix', that could eventually allow for instant object recognition. From the article: "Now, neuroscientists in the McGovern Institute at MIT have been able to decipher a part of the code involved in recognizing visual objects. Practically speaking, computer algorithms used in artificial vision systems might benefit from mimicking these newly uncovered codes ... In a fraction of a second, visual input about an object runs from the retina through increasingly higher levels of the visual stream, continuously reformatting the information until it reaches the highest purely visual level, the inferotemporal (IT) cortex. The IT cortex identifies and categorizes the object and sends that information to other brain regions."

Spy der Mann wrote to mention a piece at Physorg.com about a major breakthrough in planet finding. From the article: "On a crystal clear, star-filled night at Hawaii's Keck Observatory in Mauna Kea, NASA engineers successfully suppressed the blinding light of three stars, including the well-known Vega, by 100 times. This breakthrough will enable scientists to detect the dim dust disks around stars, where planets might be forming. Normally the disks are obscured by the glare of the starlight. Engineers accomplished this challenging feat with the Keck Interferometer, which links the observatory's two 10-meter (33-feet) telescopes. By combining light from the telescopes, the Keck Interferometer has a resolving power equivalent to a football-field sized telescope. The 'technological touchdown' of blocking starlight was achieved by adding an instrument called a 'nuller.' "

MaceyHW writes "PhysOrg.com reports a big step forward in the development of magnetic microchips. Since their initial creation of a magnetic logic gate in 2002, an international team of researchers from Durham University, Imperial College, London and the University of Sheffield 'team has created a number of further "logic gates" and created interconnecting structures using magnetic "nanowires," which can now reproduce the logic functions of a conventional computer.'"

DumbSwede writes "PhysOrg.com reports that according to calculations by B.M. Kuzhevsky, the head of the neutron research lab at Moscow State University, neutron levels far above normal background levels exist during lightning strikes. While only a small percentage of rainwater contains atoms of deuterium, the lightning still provides enough energy to create fusion events. Frequent Slashdot readers no doubt remember recent articles on Fusion induced by sonic compression and more recently by pyroelectric effect. Perhaps more controversially, and yet to be discussed on Slashdot, the NIF has possible plans for a hybrid fusion approach that uses not only deuterium and tritium, but uranium and plutonium as well in what amounts to a miniaturized version of how thermonuclear weapons achieve fusion. Fears are that this could lead directly to micro-H-bombs. This year has also seen the final selection of France for the ITER experimental Fusion Reactor site. With all the recent discoveries and developments in fusion research, my question for Slashdotters - are we on the verge of something big that will make fusion a practical reality in a much shorter time frame than the often quoted '30 years away, and always will be'?"
