Segway-Based Robot Opens Doors
Roland Piquepaille writes "In this short article, Technology Review tells us that Massachusetts Institute of Technology (MIT) researchers have built a new robot, named Cardea, which is able to push open doors and has the bottom half of a Segway scooter. Cardea will be five feet tall with a torso, three arms, a variety of sensors, and a human-like head with expressive features and vision, and mounted on a Segway base. More details and references are contained in this review which also includes several pictures. For even more details, go to the Cardea Project homepage." -

Sega Profits Surge On Arcade Titles, Despite EA Sports Domination
Thanks to Reuters for their story revealing Sega's profits jumped 485 percent for the first half of the fiscal year, to 5.93 billion yen ($54.53 million), largely due "to strong sales of its [Japanese] arcade game machines such as [popular crane game] 'UFO Catcher 7' and [intriguing arcade-based CCG] 'The Key of Avalon'." Elsewhere, Sega's consumer division "...posted an operating loss of 1.8 billion yen, but it was less than it expected because of solid sales of its soccer simulation and car racing games." However, the company "...trimmed its projection of key U.S. sports games to 1.73 million from 2.6 million units", still dogged by Electronic Arts' domination of the genre, as the president said: "We need to carefully plan how to compete with EA in terms of marketing, but we believe our games can win more market share because of their high quality." -
Why Blacklisting Spammers Is A Bad Idea
Roland Piquepaille writes "For the last two months, an eternity in Internet time, I was unable to reach -- and to contribute to -- Smart Mobs, the collective blogging effort around the next social revolution initiated by Howard Rheingold. Why that? Because an unknown customer of Verio decided it was a spamming site and asked the company to blacklist the site. Verio complied -- probably without even checking it -- and my problems started. It took me dozens of e-mails and phone calls and two visits to the headquarters of my french ISP, Noos, to fix the situation. More about this horror story is available here." -

Better Displays With New Nanowire Film
Roland Piquepaille writes "A Harvard University team has successfully applied a film of nanowires on glass and plastic. This might lead to better and flexible displays or wearable computers, says the American Chemical Society, in "Nanowire film brings cheaper, faster electronics a step closer." "By using a 'bottom-up' approach pioneered by our group, which involves assembly of pre-formed nanoscale building blocks into functional devices, we can apply a film of nanowires to glass or plastics long after growth, and do so at room temperature," says Charles M. Lieber, professor of chemistry at Harvard. The researchers think that the first applications will be improved smart cards or LCD displays. But they also have a vision for the next decade. "One could imagine, for instance, contact lenses with displays and miniature computers on them, so that you can experience a virtual tour of a new city as you walk around." This overview contains more details and references. It also includes a picture of a high-density crossbar nanostructure, whose geometry can serve as the basis for many applications, like bio-sensor arrays or high-density data storage." -

Metal Nanobumps For Better Artificial Body Parts
Roland Piquepaille writes "Everybody seems concerned these days by the risks associated with the use of nanotechnologies. So I'm pleased to report that Purdue engineers have proven that metal nano-bumps could improve artificial body parts, such as hips or knees. They based their theory on a simple fact. Surface bumps on conventional alloys used in prostheses are in the micron range, while they are ten times smaller in natural bones, around 100 nanometers. They thought a reduction of the size of these bumps in the prostheses would also reduce the risk of rejection by the body. They limited their experiments to petri dishes, but showed that adherence of new body cells to their new metal alloys was dramatically better than with existing alloys. Ssveral years will pass before improved artificial hips come to market. But the needs are growing. This overview contains more details and references." -

Turn Your Head Into Speakers
Roland Piquepaille writes "A small company based in Iowa has developed products made with a "smart" metal that can turn your walls or your head into speakers. "Last August, Etrema -- an innovative technology firm nestled in the cornfields of Ames, Iowa -- started selling those chrome discs for $1,500 a pair. Called Whispering Windows, they can turn any wall, window, or drab conference table into a speaker." The author tried the technology, and even if she needed a full bottle of Tylenol after usage, said "it's not every day that your head serves as a piece of stereo equipment." This overview tells you more about this "magic" metal, the Terfenol, which is a combination of terbium and dysprosium. The article also says that we can soon expect pirated versions of Terfenol coming from China." -

Sandia's Red Storm Detailed Architecture
Roland Piquepaille writes "Bill Camp & Jim Tomkins, from Sandia National Laboratories, have published a 77-page document about the architecture of the Red Storm supercluster being built by Cray Inc. The new nickname for the 40 teraflops system is "Thor's Hammer." Please read the full presentation if you have the time (PDF format, 3.54 MB). This technical analysis gives you the major characteristics of the system which will be operational by August 2004. With its 108 compute cabinets and its 10,368 compute node processors (AMD Opteron running at 2.0 GHz), it is expected to reach 20 teraflops on MP-Linpack. The report also looks at scalability and reliability, which are essential for a sytem which will be expanded to 30,000 processors in the future." -

4 Tons Of Plants per Mile to Ride In Your Car
Roland Piquepaille writes "As you might know, I enjoy big numbers. So it's just natural that I was attracted by this news release from the University of Utah, "Bad Mileage: 98 tons of plants per gallon." "A staggering 98 tons of prehistoric, buried plant material is required to produce each gallon of gasoline we burn in our cars, SUVs, trucks and other vehicles." For a reasonably efficient car, riding 25 miles per gallon, this translates to 4 tons of prehistoric plants per mile, or more than two tons per kilometer. The research paper also mentions that everyday, we are using the fossil fuel equivalent of all the plants growing during a whole year just for our cars. Even if these numbers are too large, this still makes you think about how inefficient our cars are. This analysis describes the calculations and contains other details about the research paper which will be published in November by Climate Change." -

NSA Turns To Commercial Software For Encryption
Roland Piquepaille writes "According to eWEEK, the National Security Agency (NSA) has picked a commercial solution for its encryption technology needs, instead on relying on its own proprietary code. "The National Security Agency has purchased a license for Certicom Corp.'s elliptic curve cryptography (ECC) system, and plans to make the technology a standard means of securing classified communications. In the case of the NSA deal, the agency wanted to use a 512-bit key for the ECC system. This is the equivalent of an RSA key of 15,360 bits." This summary includes the NIST guidelines for public key sizes and contains more details and links about the ECC technology. Since the announcement, Canadian Press reports that Certicom's shares more than doubled in Toronto." -

Writing in Space with a Cheap Ballpoint Pen
Roland Piquepaille writes "Some days bring big surprises. Like many people, I always believed that it was impossible to write in space with ordinary pens because ink would not flow. So imagine my astonishment when I read Pedro Duque's diary from space this morning. Pedro Duque is an astronaut since 1992. Now, he's on board of the International Space Station (ISS) since October 18, 2003. And he's writing -- from space -- with a cheap ballpoint pen, like Russians apparently always did: 'So I also took one of our ballpoint pens, courtesy of the European Space Agency (just in case Russian ballpoint pens are special), and here I am, it doesn't stop working and it doesn't "spit" or anything.' Isn't it amazing? This summary contains more details and a photograph of Pedro Duque on board ISS." Note that NASA didn't go crazy developing a pen for space. Surface tension is the important factor for all pens, not gravity. -

Integrating A GUI Into An Existing Medical Device
Roland Piquepaille writes "As I'm not quite familiar with medical devices, I was fascinated by this long article from Medical Electronics Manufacturing. It tells us that "new technology makes graphical user interfaces (GUIs) a fast and cost-effective way to add features and improve on existing designs" of these medical devices. And it really looks simple to use. You just need a standard PC and an HTML authoring tool to develop your GUI. It is then compiled in micro-HTML and embedded in silicon, leading to a graphical OS chip which doesn't need to be powerful or have tons of memory. "The GUI shipped with the Amulet Technologies starter kit, for example, contains almost half a megabit of information in HTML. When all of the gifs, widgets, and other files are imported and compiled into micro-HTML, the file size is reduced to a mere 66 Kb of memory." This overview contains more details and a photograph of such a GUI at work." -

What Is The Most Popular OS in the World?
Roland Piquepaille writes "If your answer is Windows, you're plain wrong. It's ITRON, a Japanese real-time OS kernel that can be customized for any small-scale embedded systems. According to LinuxInsider.com, it is used by more than 3 billion microprocessors found in mobile phones, digital cameras, CD players and many other electronic devices including even satellites. The article looks at the competition in this market, notably RTLinux, the real-time version of Linux, and T-Linux, an environment for running middleware. This last effort could lead to the eTRON chip, an encryption device that offers secure data transfer across wireless networks and the Internet. One thing is sure for this market: the future is definitively open-source. This overview contains more details and external references." -

ElectAura-Net, a 10-Mbit/second Body Network
Roland Piquepaille writes "In 'Human Body Network Gets Fast,' Technology Research News tells us that NTT Docomo researchers in Japan have created a 10-Mbit/second indoor network by using human bodies as Ethernet cables. 'The network, dubbed ElectAura-Net, is wireless, but instead of using radio waves, infrared light, or microwaves to transmit information it uses a combination of the electric field that emanates from humans and a similar field emanating from special floor tiles.' ElectAura-Net is faster than the Bluetooth radio wave system and provides a solution for indoor networks. The researchers think that this is a solution for "ubiquitous" communication, using GPS outdoor and our bodies indoor. This summary contains more details." -

Femtosecond Lasers for Nanosurgery
Roland Piquepaille writes "In "Lasers operate inside single cells," Nature writes that nanosurgery can be achieved by vaporizing some components of living cells without killing the cells themselves. "With pulses of intense laser light a millionth of a billionth of a second long, US researchers are vaporizing tiny structures inside living cells without killing them. The technique could help probe how cells work, and perform super-precise surgery." This was developed by Eric Mazur of Harvard University and his colleagues. This summary contains more details and references about the process and these microexplosions. Please note that it's a very different technique from the one described six months ago in a previous Slashdot reference, Surgery with Femtosecond Lasers." -

The Smart Sensor Web
Roland Piquepaille writes "As writes Vincent Tao for GEO World, integrating the billions of sensors already present in our environment with the power of the Web will represent 'a revolutionary leap in earth observation.' 'In short, the Sensor Web offers full-dimensional, full-scale and full-phase sensing and monitoring of Earth at all levels: global, regional and local.' The Sensor Web will need to have five characteristics to be successful. It must be interoperable, intelligent, dynamic, flexible and scalable. And the Sensor Web architecture will have four layers: a sensor layer, a communication layer, a location layer and an information layer. When it's here, it will have 'extraordinary significance for science, environmental monitoring, public safety and many other domains of activity.'

Smart People in the News: Rheingold, Gosling
Roland Piquepaille writes "In "How Will "Smart Mobs" Play Out?," BusinessWeek asked questions to Howard Rheingold, who published the "Smart Mobs" book at the end of 2002. Rheingold talks about the emergence of the picturephone, especially outside the U.S. He adds that future business applications for smart mobs might start anywhere in the world, like "finding out about the spot labor market in [an] African village." For his part, James Gosling, the leading guy behind the Java programming language, is interviewed by Red Herring, in Social smarts. He talks about the social implications of the Internet by looking at the Brazilian National Medical System. Gosling also talks about the entertainment industry which deeply hates Internet, and about the open source movement, of which he is a big fan. And of course, that leads him to talk about Microsoft. This summary contains some excerpts of both interviews." -

Satellite-Assisted European Road Tolls Next?
Roland Piquepaille writes "In 'Pay-as-you-go motoring just around the corner,' the European Space Agency (ESA) says that "road tolls could be made fairer if satellite-assisted distance pricing is implemented." Experiments are currently underway in Ireland, Portugal and Germany, before a possible extension to other countries. Potential benefits of such a road tolling system would be fairer implementation of charging on a 'pay for use' basis. All these experiments are using the US-operated Global Positioning System (GPS). But in 2010, when the system is fully implemented, it will use the Galileo satellite system." -
More Criticism of SCO's Claims To UNIX
inc_x writes "GROKLAW has a compelling analysis that shows that SCO's claims that it owns the UNIX operating system are not very truthful. The Open Group confirms this position: "Statements that SCO "owns the UNIX operating system" or has "licensed UNIX to XYZ", are clearly inaccurate and misleading." It seems that SCO finds it increasingly difficult to distinguish facts from fiction. Last week SCO claimed 'This IP battle is only one part of SCO's business and is an add-on component. The core of SCO's business is profitable,' not bothered by the fact that they had claimed the opposite in their SEC filing: 'If we do not receive SCOsource licensing revenue in future quarters and our revenue from the sale of our operating system platform products and services continues to decline, we will need to further reduce operating expenses in order to maintain profitability or generate positive cash flow.'" -

Cleaning the Environment with Iron Nanoparticles
Roland Piquepaille writes "In "Nanoscale Iron Could Help Cleanse the Environment," the National Science Foundation (NSF) reports that "nanoscale" powder made from iron could be used to clean contaminated soil and water. "Iron's cleansing power stems from the simple fact that it rusts. When metallic iron oxidizes in the presence of contaminants, these organic molecules get caught up in the reactions and broken down into simple carbon compounds that are far less toxic." Using this technology, cleaning landfills or industrial sites would cost about $5 per square meter. More details are available in this summary, including other links and a diagram showing how the method works." -

Nanoparticles Change Crystal Structure When Wet
Roland Piquepaille writes "This news release from the University of California at Berkeley is quite astonishing. 'A UC Berkeley team comprised of physicists, chemists and mineralogists reports on the unusual behavior of a semiconducting material, zinc sulphide (ZnS), when reduced to pieces only 3 nanometers across. They found that when the surface of a ZnS nanoparticle gets wet, its entire crystal structure rearranges to become more ordered, closer to the structure of a bulk piece of solid ZnS.' My summary includes two images of a 3 nanometer zinc sulphide (ZnS) nanoparticle with or without surface-bound water. How can this be used for? Surprisingly, they think that it 'could provide a way to tell whether pieces of rock from outer space came from planets with water.'" -

Sci-Fi Movies and 'Bad Science'
Roland Piquepaille writes "Science fiction movies can be fun, and sometimes boring, when Hollywood producers want to show us a 2 1/2 hour film when 90 minutes would be enough. But what about the 'science' behind them? BBC News says it's pretty bad in 'When sci-fi forgets the science.' For example, the metamorphosis of Bruce Banner into The Hulk, based on work of marine biologist Greg Szulgit from Hiram College, Ohio, about sea cucumbers, is qualified by himself as "really awful"." The Insultingly Stupid Movie Physics website, which we've previously mentioned, is referenced in this article, and is now freshly updated to deal with movies like The Hulk. -
Embarrassing Dispatches From The SCO Front
An anonymous reader writes "Dennis Ritchie has acknowledged he with Ken Thompson wrote the code cited as 'proof' by SCO. This seems to fit perfectly with Bruce Perens' Analysis of SCO's Las Vegas Slide Show, and undermine Blake Stowell's claim 'At this point it's going to be his word against ours." Andreas Spengler writes "In the ongoing battle between SCO and the Linux community, German publisher Heise has shown that not only was the Linux implementation of the Berkeley Packet filter written outside of Caldera (now SCO), but that it was common practice there and at other companies to remove the BSD copyright notices from the internally used source code. In effect, SCO has proven publicly that they violated the BSD license." (Warning, article is in German.) Finally, a semi-anonymous reader writes "Learn all about how IBM's stomach will be roasted on a pyre of CDs at WeLovetheSCOInformationMinister."
