Software Agents Can Help Time-Stressed Teams
Roland Piquepaille writes "Penn State researchers have developed software agents which can help human teams to react more accurately and quickly in time-stressed situations than human teams acting alone. According to this news release, the software was tested in a military command-and-control simulation. "When time pressures were normal, the human teams functioned well, sharing information and making correct decisions about the potential threat." But when the pressure increased, the human teams made errors who would have cost lives in real situations. The decisions taken by agent-supported human teams were much better. Now, it remains to be seen if this software can be used in other stressful situations, such as for emergency management operations. Read more for other details, references and illustrations about this project." -

Can Cell Phones Damage Our Eyes?
Roland Piquepaille writes "I'm sure you've read dozens of stories about how our cell phones could be dangerous to our health, causing brain tumors for example. But so far, there is not a definitive answer. But now, according to IsraCast, a team of Israeli researchers has discovered that the microwave radiation used by our cell phones could destroy our eyes by causing two kinds of damages to our visual system, including an irreversible one. If the researchers are right, and even if you only occasionally use your cell phone, the lenses in your eyes can suffer from microscopic damages that won't heal themselves over time. As this study has not been not done -- yet -- on humans, I guess the controversy can begin and that another scientific team will soon tell us that this study is not correct. In the mean time, read more for other details and references. And whether you think that cell phones can damage our eyes or not, feel free to post your comments below." -

The Hawaiian Autonomous Undersea Robot
Roland Piquepaille writes "After several years of research, engineers from the University of Hawaii are now testing the first autonomous robotic vehicle for deep-ocean work in the U.S. This robot is called SAUVIM, short for Semi-Autonomous Underwater Vehicle for Intervention Missions. It's roughly the size of an SUV and it is designed to operate to a depth of about 4 miles. With its computers, its sensors, and a 5-foot, 150-pound autonomous manipulator, or robotic arm, it will be able to move towards a specific target, such as a wrecked pipe laying on the ocean floor -- and maybe fix it. Right now, this robot has an autonomy of about eight hours, but this range should soon be extended when the researchers move from batteries to fuel cells to power the undersea vehicle. This overview contains other details, references and several pictures of this autonomous submarine engine." -

Alex, The Brainy Parrot Who Knows About Zero
Roland Piquepaille writes "Alex is a 28-year-old grey parrot who lives in a lab at Brandeis University in Waltham, Mass., and can count, identify objects, shapes, colors and materials. And now, Alex has grasped the concept of zero, according to World Science. In fact, Alex can describe the absence of a numerical quantity on a tray containing colored cubes. When a color is missing, Alex consistently identified this 'zero quantity' by saying the label 'none.' You might think that this is just a parrot trick, but this research about 'bird intelligence' might also help autistic and other learning-disabled children 'who have trouble learning language and counting skills.' This overview contains other details, references and a picture of Alex counting his colored cubes." -

Eastern Ink Painting on a Computer
Roland Piquepaille writes "Traditional Oriental ink painting is more easily done with real brushes than with a computer program because you need to model how the ink is flowing into an absorbent surface such as paper. In this brief article, Technology Research News writes that "researchers from the Hong Kong University of Science and Technology have developed a brush-and-ink-style paint program, dubbed MoXi, that uses a model of pigment particles in water flowing into paper." These virtual Chinese brushes simulate in real time the ink dispersion and could be available on your PC within two years. This longer overview contains more details and references. It also includes pictures generated with MoXi. Finally, it looks at a potential trademark problem over the name MoXi." -

Our Brains Don't Work Like Computers
Roland Piquepaille writes "We're using computers for so long now that I guess that many of you think that our brains are working like clusters of computers. Like them, we can do several things 'simultaneously' with our 'processors.' But each of these processors, in our brain or in a cluster of computers, is supposed to act sequentially. Not so fast! According to a new study from Cornell University, this is not true, and our mental processing is continuous. By tracking mouse movements of students working with their computers, the researchers found that our learning process was similar to other biological organisms: we're not learning through a series of 0's and 1's. Instead, our brain is cascading through shades of grey." -
The Virtual Planet Explorer
Roland Piquepaille writes "A European Union program has helped several European partners to develop the Virtual Planet (or V-Planet) software, which will enable its users to browse and interact in three dimensions with any part of our planet, according to IST Results. "Using Vplanet Explorer, anyone can set off on a journey to discover new regions in 3D, rather than staring at a flat map and trying to picture its scenery," says Eric Martin, coordinator of the IST project. The software can also be used for technical simulations and has already been used by both Airbus and Boeing. It should be available this summer for about 10,000 euros (about $12K). Besides other details and references, this overview contains several pictures of simulations using V-Planet." -

'Haute Cuisine' on Mars
Roland Piquepaille writes "If you're lucky enough to be a crew member of one of the next European Space Agency (ESA) long-term missions, you will have the choice between eleven new delicious recipes, such as 'martian bread and green tomato jam' or 'potato and tomato mille-feuilles' when it's time for dinner. In 'Ready for dinner on Mars?,' ESA says that these recipes will use fresh ingredients grown in greenhouses built on Mars colonies or other planets. The future astronauts -- should I write 'farmonauts'? -- will grow potatoes, onions, rice, soya or lettuce. And it's interesting to note that the new menus were elaborated with the help of Alain Ducasse, the French chef who has almost as many stars in the 'Guide Michelin' as there are planets in our Solar system. This overview contains more details and references about eating in space." -

Decoding the Genome: Serious Infrastructure
Roland Piquepaille writes "The Wellcome Trust Sanger Institute is one of the largest genomics data centers in the world. In "The Hum and the Genome," the Scientist writes about the IT infrastructure needed to handle the avalanche of data that researchers have to analyze. With its 2,000 processors and its 300 terabytes of storage, the data center uses today about 0.75 megawatts (MW) of power at a cost of 140,000 per year (about $170K). But the data center will need more than a petabyte of storage within three years, and its yearly electricity bill will reach 500,000 (more than $600K) for about 1.4 MW, enough to power more than a thousand homes. The original article gets all the facts, but this summary contains all the essential numbers." -

The Diagnostic 'Bugbot'
Roland Piquepaille writes "The Pittsburgh Post-Gazette reports that a robot combined with a swallowable camera could give doctors a better look inside the small intestine. This medical robot, dubbed 'bugbot,' is being developed at Carnegie Mellon University (CMU) in its NanoRobotics Laboratory. It will measure less than 800 nanometers in diameter and will transmit thousands of images during its trip inside yourself with its embedded camera. With the six legs attached to the microrobot, CMU researchers want to give more control to camera operators, such as coming back to a suspected lesion. This robot should be ready for human inspection within 2 to 3 years and opens the way for future nanorobots. This overview contains more details about this project." -

Cellphedia, a SMS Social Network Service
Roland Piquepaille writes "Based on ideas taken from Wikipedia and dodgeball, Cellphedia allows its members to broadcast questions to its community and receive answers, using SMS text messaging on cell phones. Here is how it works, according to "Cellphedia Melds Facts with Mobile Smart Mobs" from E-Commerce Times. First, you register for free on the site and you indicate your subjects of interest. If you want to ask a question, it is sent to all the members who expressed interest in this particular subject. Finally, the first answer received by Cellphedia is sent back to you. This means that later answers, which could have been more accurate, are discarded. But this service is still very young and its creator is working hard to improve it. Read more for some examples of questions and answers stored on the Cellphedia central server." -

RFID Bracelets to Track Inmates in L.A. County
Roland Piquepaille writes "According to RFID Journal, the Los Angeles County Sheriff's Department is about to launch a pilot program to track 1,800 inmates using RFID devices. If the test is successful, the technology will be deployed for the 18,000 inmates of the L.A. county jails. With this system, inmates carry a wrist bracelet which issues a signal every two seconds and is caught by RFID readers installed everywhere in the prison. Officers and staff also carry a RFID device attached to their belts. And a central server keeps track in real time of the position of all prisoners and guardians. Besides tracking locations, the system also intends to reduce violence within the jail and to avoid escapes. If this system works as its promoters think, the potential market to equip all federal, state and county jails in the U.S. exceeds $1 billion. This overview contains other details and references, including a picture of a wristwatch transmitter worn by inmates." -

Rejected Scientific Paper Recycled as an Ad
Roland Piquepaille writes "In this article, The Scientist reveals a curious and probably unique story. Two years ago, a researcher at Brown University submitted a paper to a scientific medicine journal. Then he received a note from the editor saying that his paper would not interest the journal readers. Thinking that his article was unfairly rejected before peer review, he decided to publish a two-page ad with the contents of his paper in the same journal. He even asked readers if they thought the contents interesting and received 33 positive replies. Read this summary before telling me what you think and if you've heard about a similar story." -

The Sharpest Ever Global Earth Map
Roland Piquepaille writes "The GLOBCOVER project, started by the European Space Agency (ESA), has a very simple goal. It will create the most detailed portrait of the Earth's land surface with a resolution three times sharper than any previous satellite map. The image acquisition will be done throughout 2005 and use the Medium Resolution Imaging Spectrometer (MERIS) instrument of the Envisat environmental satellite. To create this sharp map, the GLOBCOVER project will analyze about 20 terabytes of data gathered by the European satellite. When it's completed, the map will have numerous uses, 'including plotting worldwide land use trends, studying natural and managed ecosystems and modelling climate change extent and impacts.'" -
Secure Video Conferencing via Quantum Cryptography
Roland Piquepaille writes "If you use a webcam to talk with your mom, this tool is not for you. But if you're working for a company and that you have to routinely discuss about sensitive future projects or the possible acquisition of another company, you need more security, and this new video conferencing system based on quantum cryptography is a tool you need. According to this article from Nature, researchers from Toshiba have developed a system which can generate 100 quantum 'keys' every second, fast enough to protect every frame in a video exchange. This technology, which today is working over a distance of about 120 kilometers, could become commercially available within two years at an initial cost of $20,000. This overview contains more details and references." -

When Lofar Meets Stella
Roland Piquepaille writes "The LOFAR (Low Frequency Array) telescope is a new IT radio-telescope which will use about 20,000 simple radio antennae when it's completed in 2008. At this time, it will cover an area with a diameter of 360 kilometers centered over the Netherlands. Its small radio antennae will detect radio wavelengths up to 30 meters, and because the ionosphere can bend some of these radio waves, the Lofar images might be somewhat blurry. So all the information captured by these antennae will be digitized and sent to a computing facility at a rate of 22 terabits/second today, and almost 50 terabits/second in 2010. This is the reason why Lofar needs Stella, an IBM supercomputer installed recently in Groningen, also in the Netherlands, to process signals from up to 13 billion light years from Earth. Stella consists of 12,000 PowerPC microprocessors and has a computing power of 27.4 teraflops. This overview contains more details and a picture about the Lofar-Stella interaction." -

Writing with a Nanoscale Fountain Pen
Roland Piquepaille writes "I'm sure that almost all of you have used a fountain pen. But imagine a pen drawing lines only 40 nanometers in width. Now, it can be done with the Nanofountain Probe (NFP) developed by scientists at Northwestern University. This innovative fountain pen "employs a volcano-like dispensing tip and capillary fed solutions to enable sub-100 nanometer molecular writing." But it needs to be mounted on an atomic force microscope (AFM) to be useful, so it probably is something you'll not find at your local drugstore for a while. However, this nanofountain probe could have applications for nanosensors, biotechnology and pharmaceuticals. Read more for other details, pictures and references." -

A New Way to Grow Bones
Roland Piquepaille writes "As it is often the case, a recent discovery just came out from a simple idea. By studying diseases in which the human body generates too much bone, UCLA researchers have discovered a natural molecule that can be used to generate new bone growth in patients who lack it. This new molecule has aptly been named UCB, or University of California Bone. This new protein for growing bones is more precise and has fewer side effects than the ones currently used by orthopedic surgeons to aid in bone repair. But if you suffer from a bone deficit today, you'll have to wait almost ten years before an FDA approval and a commercial introduction of products based on this discovery. Read more for other details and references, plus a picture of a bone defect corrected by the UCB." -

A Plasmonic Revolution for Computer Chips?
Roland Piquepaille writes "Today, we're using basically two ways to move data in our computers: transistors carry small amounts of data and are extremely small, while fiber optic cables can carry huge amounts of data, but are much bigger in size. Now, imagine a single technology combining the advantages of photonics and electronics. This Stanford University report says a new technology can do it: plasmonics. (For more about plasmons, read this Wikipedia article.) Theoretically, it is possible to design plasmonic components with the same materials used today by chipmakers, but with frequencies 100,000 times greater than the ones of current microprocessors. There is still a challenge to solve before getting plasmonic chips. Today, plasmons can only travel a few millimeters before dying, while today's chips are typically about a centimeter across. Read this overview for more details and references about plasmonics, and to discover why it's one possible future for chips' circuitry." -

Burn Grass, Get Green Biofuel
Roland Piquepaille writes "Do you want to use an economical and environmentally friendly biofuel? Just grow grass. Burning grass pellets will produce an energy-efficient biofuel, according to Jerry Cherney, a professor of agriculture at Cornell University. In this news release, 'Grass as Fuel,' he says "Burning grass pellets makes sense; after all, it takes 70 days to grow a crop of grass for pellets, but it takes 70 million years to make fossil fuels." Unfortunately, there is nothing like a grass political lobby in Washington, so he might not be heard. But with current oil prices, more and more people will be tempted to use cheaper -- and cleaner -- sources of energy. This overview contains many more details and references about this environmentally friendly biofuel made from grass." -

Nano-Probes Stay Inside a Cell's Nucleus for Days
Roland Piquepaille writes "Researchers from the Lawrence Berkeley National Laboratory (LBL) have developed fluorescent and stable nano-probes which can stay inside a cell's nucleus for hours or even days. According to this LBL news release, this will help biologists to better understand nuclear processes that evolve slowly, such as DNA replication, genomic alterations, and cell cycle control. This research was partially based on previous investigations about quantum dots. Now, the researchers want to tailor their quantum dots, which emit different colors depending on their sizes, to check specific chemical reactions inside nuclei, such as how proteins help repair DNA after irradiation. Read more for other details and references and to see how a nano-sized probe is entering a cell's nucleus." -

Robotic Nanotech Swarms on Mars... in 2034
Roland Piquepaille writes "NASA is testing a shape-shifting robot called 'TETwalker' for tetrahedral walker, because it looks like a flexible pyramid. It has been tested in the lab and at the McMurdo station in Antarctica to test it under conditions more like those on Mars. Now, it is on the way to be -- really -- miniaturized by using micro- and nano-electro-mechanical systems. These robots will eventually join together to form 'autonomous nanotechnology swarms' (ANTS). When it's done, in about thirty years, these nanotech swarms will 'alter their shape to flow over rocky terrain or to create useful structures like communications antennae and solar sails.' So in 2034, nanotechnology will land on Mars. Read more for other details and references about the TETwalker and the ANTS project." -

Computerworld writes that they're not enough standards in this industry and asks a fundamental question: who will administer these building networks, IT or facilities managers? Take for example Yale University which wants to connect 210 campus buildings, but also wishes "to integrate the BAS with the university's accounting system for billing and chargeback." Imagine the security risks involved with such an approach. This shorter summary contains selected excerpts of this must-read article." -

3D Virtualization Edges Toward the Mainstream
Roland Piquepaille writes "With recent improvements in graphic cards and in powerful Linux-based PC clusters, virtual 3D prototypes are rapidly replacing actual physical prototypes in a wide range of industries, including early adopters such as aerospace or car companies. But now, software designers are also incorporating sound and tactile feedbacks to their Virtual Reality (VR) systems for real product development. In this long article, Desktop Engineering gives several examples of these new VR developments. But even if PC clusters and off-the-shelf graphic cards are cheap, a state-of-the-art VR facility such as an immersive CAVE can still cost more than one million dollars, because you need to build the viewing facility and buy expensive projection systems. However, costs are still decreasing and virtual prototyping is reaching the mainstream stage. This overview contains selected excepts and comments." -

Taking Care of Mobile Patients
Roland Piquepaille writes "After a patient has been hospitalized for a surgical intervention, he usually wants to return to his normal life. But doctors would like to monitor him to be sure that the operation was successful. How can they manage this without being too intrusive? In "Health Care Monitoring of Mobile Patients," Italian researchers offer a three-layer networking solution. First, a body area sensor network would continuously record your cardiac activity or your body temperature. A second level would involve a home sensor network, including for example a PC wirelessly receiving this information. Finally, this home network would be able to alert an hospital network if needed. Right now, this whole idea is at the proof-of-concept level, but it really looks promising." -
Smart Holograms Used as Biosensors
Roland Piquepaille writes "In this short article, eWEEK writes that the next generation of biosensors will consist of small holograms costing only fractions of a cent. Prototypes developed by a U.K. company, aptly named Smart Holograms, include contact lenses that monitor glucose levels or thin badges that detect alcohol levels. Not only these holograms used as sensors will be cheap to produce, they'll also require less training for nurses or police officers. This is because these holograms can be designed to show results graphically, such as morphing into an image of a green car if someone subjected to breath analysis is sober and can drive. Read this overview for other details and an illustration showing how to create a sensor hologram." -

Wearable PC with an Artificial-Reality Helmet
Roland Piquepaille writes "In this short article, InformationWeek writes that 'two sexy technologies that flamed out five years ago -- wearable computers and artificial reality -- are combined in a new training-development system' for the military. This system, developed by Quantum3D, includes a binocular head-mounted OLED display and head-leg-weapon motion-tracking systems, integrated with a vest-worn tactical visual computer. It runs under Windows XP and is compatible with the 802.11 a/b/g wireless networking standards. It will be used by the infantry to train soldiers, but it looks so complex that I would need intensive training just for using it.
