Shrimp-Based Bandages Save Lives
Roland Piquepaille writes "Unstoppable bleeding is one of the leading causes of death on battlefields. But now, soldiers in Iraq and Afghanistan have a way to reduce bleeding when they're wounded. In "War Bandages," ScienCentral News writes that these new bandages contain chitosan molecules, extracted from shrimp shells. These positively charged chitosan molecules attract negatively charged red blood cells, stopping hemorrhage in one to five minutes. As said one of the co-founders of the Oregon-based company behind these bandages, "You can have a hole in your heart and 60 seconds later it's sealed." The Food and Drug Administration approved these bandages for human usage, but today they are exclusively sold to the Army. With a $90 price tag for a 4-inch-by-4-inch single bandage, would you buy them anyway? This overview contains more details and references. It also shows you how the red blood cells are attracted by the chitosan molecules." -

Connecting Devices With Wireless Grids
Roland Piquepaille writes "A new concept is emerging in networking: wireless grids. These grids connect all kinds of wireless devices, such as sensors or cell phones, with each other and with more traditional wired grids. IEEE Internet Computing has devoted a very long and thorough article about these wireless grids which can deliver new resources, locations of use, and institutional ownership and control patterns for grid computing via ad hoc distributed resource sharing." (Read more below.)"The article says that applications for wireless grids fall into three classes: the ones which aggregate information from the range of input/output interfaces found in nomadic devices, those which focus on the locations and contexts in which the devices exist, and those that leverage the mesh network capabilities of collections of nomadic devices. The authors add that these grids "emerged from a combination of the proliferation of new spectrum market business models, innovative technologies deployed in diverse wireless networks, and three related computing paradigms: grid computing, P2P computing, and Web services." If you're interested in the future of wireless networks, the original article is a must-read, but check this summary if your time is limited."

New Robots and the Ten Ethical Laws Of Robotics
Roland Piquepaille writes "The robotics actuality is pretty rich these days. Besides the fighting robots of Robo-One and the flying microrobots from Epson (the best picture is at Ananova), here are some the latest intriguing news in robotics. In Japan, Yoshiyuki Sankai has built a robot suit, called Hybrid Assistive Limb-3 (or HAL-3), designed to help disabled or elderly people. In the U.S., Ohio State University is developing a robotic tomato harvester for the J.F. Kennedy Space Center while Northrop Grumman received $1 billion from the Pentagon to build a new robotic fighter. I kept the best for the end. A Californian counselor has just patented the ten ethical laws of robotics. A good read for a Sunday, if you can understand what he means. This summary only focuses on HAL-3 and one of the most incredible patents I've ever seen, so please read the above articles for more information about the other subjects." -

NASA Helps Clearing The Fog
Roland Piquepaille writes "NASA's Aviation Safety and Security Program wants to cut fatal accident rates by 80 percent over the next ten years. To reach this goal, NASA researchers used "tunnel-in-the-sky" synthetic vision systems (SVS) in recent flights on a Gulfstream V over Reno, Nevada. A guest pilot for Aviation Week & Space Technology (AWST) went onboard and writes that 'NASA Team Brings Synthetic Vision to Maturity.' He was able to see that SVS concepts, such as voice-controlled synthetic vision displays, a runway incursion protection system, database integrity monitoring technology, and enhanced vision sensors meshed with SVS images, were really effective in eliminating low-visibility-induced accidents. However, NASA doesn't say anything about the availability of SVS for commercial airlines. This summary contains more details and illustrations about key SVS concepts." -

Virtual Reality Helps to Treat Babies' Hearts
Roland Piquepaille writes "In Denmark, about 350 babies need to be operated each year because of heart defect. And their hearts are very small, so it's hard to know the exact kind of defect before the operation. This is why the Aarhus University Hospital is using virtual reality software to model babies' hearts, according to BBC News. Now, surgeons and doctors can visualize a magnified heart in 3D before planning cardiac surgery. This also allows a better communication with parents which can understand what's wrong with their babies before the intervention. As the percentage of affected babies, about one per cent, is probably the same in many other countries, let's hope this software will be widely distributed. Congratulations to these Danish doctors and software writers for this brilliant usage of technology. This summary contains more details and pictures." -

3D Holograms Detect Fake Signatures
Roland Piquepaille writes "Several sources reported last week that a new technique that produces 3D holograms of handwriting could be used to detect fake signatures on checks, credit card receipts or other important handwritten documents. Here are pointers to Nature, Scientific American or BBC News Online. Instead of using 2D techniques to look at the sequence of pen strokes in a signature, this new method is based on 3D micro-profilometry which permits to translate the writing into an image showing dips and furrows of the sample so that anomalies can be detected. If you plan to imitate your spouse's signature, beware! Forensics have a new and very efficient tool. As an example, for the use of ballpoint pens on normal paper, the success rate was 100%. You'll find more details, references and pictures in this overview." -

Moving Water Molecules By Light
Roland Piquepaille writes "An interdisciplinary team of researchers at Arizona State University (ASU) has discovered a new nanotechnology effect, the ability of moving water molecules by light. This is a far better way than current methods such as damaging electric fields and opens the way to a new class of microfluidic devices used in analytical chemistry and for pharmaceutical research. For example, this makes possible to design a device that can move drugs dissolved in water, or droplets of water and samples that need to be tested for environmental or biochemical analyses. Please read this overview for more details and references, plus an image of two water drops illuminated with a fluorescent dye and sitting respectively on a nanowire surface and on a flat surface." -

The World's Largest Environmental Experiment
Roland Piquepaille writes "The Amazon in South America is more than a forest or an habitat. It's a climate regulator which has to absorb between 200 and 300 million tons of carbon dioxide emissions produced by the 8,000 square miles of destroyed forests every year. In 1998, the Brazilian community, helped by many international institutions, launched the Large Scale Biosphere-Atmosphere Experiment (LBA). The LBA Experiment is made up of 120 projects, 61 of which are already complete. The status of these projects is currently being reviewed by 800 delegates from 170 Brazilian and foreign institutions at the III LBA Scientific Conference held in Brasilia between July 27 and 29. NASA says it plays a key role in the LBA experiment through the use of its satellites and its computer scientists. But Inter Press Service reports that the Mega-Amazon Research Project Holds Surprises -- Good and Bad: good because it provides opportunities for 400 researchers to work on postgraduate studies in the area, bad because it's still not known if the forests absorb enough carbon to compensate the emissions caused by deforestation, therefore contributing to global warming. Please read this overview for more details, references and a map of the LBA sites spanning the Amazon." -

On the Supercomputer Technology Crisis
scoobrs writes "Experts claim America has been eating our 'supercomputer feed corn' by developing clusters rather than new supercomputer processors and interconnects. Forbes says America is playing catch-up and that the new federal budget items are too little too late. Cray is laying people off due to decreased federal spending and claims lower margin products have forced them to create products based on commodity parts. Red Storm, one of their new Linux-based products, is being delayed to next year." -
U.S. Nuclear Cleanup Carries Major Risks
Roland Piquepaille writes "New Scientist reports in this pretty alarming article that there is a 50-50 chance of a major radiation or chemical accident during the cleanup of the dirtiest nuclear site in the U.S. There are indeed lots of things to clean at the Hanford complex in Washington state: 67 tons of plutonium and 190 million liters of liquid radioactive waste stored in underground tanks. A third of them, dating from the Cold War, have already leaked 4 million liters in the environment, contaminating the groundwater and a river. Meanwhile, officials at the DOE, who'll spend $50 billion between now and 2035 on this cleanup, seem less worried than the different specialists interviewed by New Scientist. Please read this overview for selected quotes from the article and from the Hanford site. You'll also find a slide from the DOE showing the timeframe for the cleanup." -

Mapping The Tour de France Riders From Space
Roland Piquepaille writes "It was just a matter of time before someone gets the idea of using satellite localization to map the positions of the cyclists of the Tour de France. In a first test on July 21 during the ascension to l'Alpe d'Huez, ten riders were equipped with receivers and tracked by the EGNOS European satellite positioning system, a preparatory programme for the Galileo system. The European Space Agency (ESA) reports about this first test in "The best view of the Tour is from space." It's highly possible that all riders can get receivers as soon as next year. And this data will be available on the Web, so you will know in real time the exact location of your favorite champion. Read this summary for more details and a computer-generated image showing the respective positions of Lance Armstrong and Richard Virenque, the top-ranked climber, while climbing to the top of l'Alpe d'Huez." -

More on the Jackito Tactile PDA
Roland Piquepaille writes "A week ago, I wrote a column about a new Tactile Digital Assistant (TDA), the Jackito. Several Slashdot readers questioned the existence of the product and thought it might be an elaborate scam. I also had serious doubts. But as both the company behind this TDA, Novinit, and myself are French, I decided to investigate and contacted the company. And I spent several hours with the CEO and the CTO. I told them about the mistakes they made in their early announcement and asked what kind of corrective actions they were taking to fix the situation and build trust in their product. I also discussed their vision of this TDA, the history of the project and its possible future. But more importantly, I used an early prototype. I don't know if this TDA will be a success, but one thing is sure: it's real. Read this interview for more details." -

NASA Preps Mars Underground Mole
Roland Piquepaille writes "People at NASA never cease to surprise me. Searching for water or presence of past life of Mars obviously needs drilling beneath the surface. So NASA is developing the Mars Underground Mole (MUM), based on a previous device used for the European Beagle 2 mission. But here is the twist. MUM will include sensors which were previously used to collect spectral imagery of Earth from pilotless aircrafts, especially Hawaii, according to NASA. While the Mole will stay on the surface on Mars and drill up to 5 meters deep, it will transmit data via a fiber optic cable to a digital array scanning interferometer (DASI). And the spectral images produced by the DASI will enable researchers to identify possible water, ice, organics and minerals under the surface on Mars. And this MUM will be a small one, weighing less than a kilogram for a length of only 50 centimeters. For more details and pictures about MUM, please read this overview." -

Yahoo! Acquires Oddpost
weiyuent writes "We all know the arrival of Gmail has initiated a new round of competition amongst the major webmail providers. Well, Yahoo! has acquired Oddpost and will be integrating Oddpost's amazing interface to strengthen its offerings. One might wonder though how to reconcile Oddpost's MSIE requirement with Yahoo!'s (thus far) cross-platform approach. Oh well, at least it will likely put an end to Oddpost's exasperating attempt to be cute in their communication." -

Forget the PDA, Here Comes the TDA
Roland Piquepaille writes "A French company has just started to sell the Jackito, the first 'Tactile Digital Assistant' (TDA). This new kind of PDA has no stylus, doesn't offer handwriting recognition and has no keyboard. Instead, it is based on touchscreen technology and relies entirely on your thumbs for input -- which are harder to lose than a stylus. And as Jackito has two simultaneous touch points, you can operate it with your two thumbs at the same time, at least according to the company. For an entry price of $600, you'll get parallel-processing capabilities with 7 processors and plenty of brand new technology, including 3ActilOS, a multitasking OS, which is not even referenced by Google. So be warned before purchasing one! However, the approach is pretty unique and I wish them good luck. Before opening your wallet, you'll find some selected pictures in this summary." -

Data Mining Goes 3D
Roland Piquepaille writes "At Sandia National Laboratories (SNL), a data mining and visualization software suite developed in the last two years is now able to extract information from many sources of data and to return 3D images as results. In Sandia's intelligence lab converts business data into 3-D images, the New Mexico Business Weekly reports that Sandia's Information Visualization Lab is able to search structured documents, such as scientific journals, or unstructured ones, such as the Web or an intranet. Since the lab has been established five months ago, this software has already been used to determine the potential of several partnerships with SNL. Other firms, such as Lockheed Martin, also are starting to use the lab. Let's hope that SNL releases this software as open source. It should be fun to use it. For more details and pictures, please read this overview." -

GPS on Mars?
Roland Piquepaille writes "SPACE.com published two days ago an article named "Red Planet Wayfinder: A GPS System for Mars." You'll read that NASA researchers are studying a 'global positioning satellite (GPS) system around Mars that could also function as a communications network.' This would imply 'a constellation of microsatellites, or Microsats, and one or more relatively large Mars Aerostationary Relay Satellites, or MARSats,' according to the Mars Network website at NASA's Jet Propulsion Laboratory (JPL). This sounds like a neat idea, but there are several issues here. First, the JPL site mentioned above has not been updated since 1999. Then, there is no mention of such a mission at NASA's Mars exploration program website. So, here is my question: is this a recycled 4-year old article? In this overview, you'll find some spectacular images and more indications leading to think that the article was written in 2000. And please note that a Slashdot reader asked last December 'Whatever Happened To The Mars Network?' without receiving an adequate answer." -

Jumping From Computer To Computer
Roland Piquepaille writes "Imagine a world where computers become so ubiquitous that the idea of carrying a laptop will almost be laughable, a world where any computer could be your computer! According to the Pittsburgh Post-Gazette, this is the goal of Intel Research Pittsburgh's Internet Suspend/Resume (ISR) project, a project that may one day let your work jump from computer to computer without interruption by using the Internet, distributed file systems, and virtual machines. When the non-proprietary technology becomes available, a user will suspend a task on the computer he's working on, and resume this work using another computer in another part of a city or several thousands of miles away. The second system will look identical to the first one, with the same files and applications opened. This technology would also ease OS upgrades or eliminate the pain coming from a hard disk failure. The project has even a feature named Rollback which would permit to go back in time, eliminating these pesky viruses. A pilot test will start this fall, so don't expect to be able to use ISR for a while. You'll find more details and references in this overview." -

A Video Projector That Fits In Your Pocket
Sven-Erik writes "Video projectors able to project high-quality images will be embedded in your cellphones and laptops within two years. This is the promise of a new technology developed at Cambridge University. These pocket projectors will have no lenses and no light bulbs. Instead, these future battery-powered tiny projectors will rely on holographic technology and special algorithms. In 'Holograms enable pocket projectors,' Technology Research News explains that a 2D hologram will be created on a microdisplay and projected by using a laser beam. This has been possible because the researchers have written special algorithms which generates the holograms a million times faster than standard ones."

Reducing Electricity Bills For Buildings With XML
Roland Piquepaille writes "Even if new buildings are connected to Internet, they usually don't communicate between themselves. And when it comes to electricity, these buildings are selfish and consume what they want without any coordination. Now, an XML-based system developed at Lawrence Berkeley National Laboratory is using Web services to collectively adjust power usage to variations in price. In 'Internet ups power grid IQ,' Technology Research News reports that the system was successfully tested for two weeks on five commercial buildings. 'Beyond price, systems could be programmed to respond to changes in air quality or to tap into sustainable energy sources.' You'll find more details, pictures and references in this overview. [Additional note: The system described here is completely different to the one mentioned in Slashdot last March in Building the Energy Internet.]" -

[Additional note: The system described here is completely different to the one mentioned in Slashdot last March in Building the Energy Internet.]" -
Smart Satellite Sets Its Own Priorities
Roland Piquepaille writes "Currently, satellites take pictures of whatever is in front of their cameras. But hydrologists from the University of Arizona (UA), working with the Jet Propulsion Laboratory (JPL) are creating spacecraft that think for themselves. Their smart software, which is tested on NASA's EO-1 satellite, can be used on all kinds of spacecraft. This software has three components: an image formation module, a science algorithm module, and a continuous planning module. This onboard planner reschedules what to film in conjunction with what the scientific algorithms have detected. This software has already detected floods in Australia and will be adapted to also detect volcano eruptions and changes in ice fields. More details and references are available in this overview, including images of the flood detected by this smart software." -

Cars To Be Assembled Atom By Atom
Roland Piquepaille writes "In a new article, the Detroit News says that the adoption of nanotechnology by car manufacturers will produce safer, lighter and cheaper vehicles. While GM is already using nanocomposite materials for several vans, Ford is developing new nanoengineered catalysts to replace platinum. The newspaper gives other examples, such as auto-adaptive suspension systems, scratch-resistant paints or nanocoated windshields which will not crack. In fact, all parts in a car can be improved by using nanotechnology, according to the article. And if automakers are only going to introduce limited amounts of nanotechnology-related products in the next few years, their usage should be widespread within ten years. More details are available in this overview." -

Slashback: Munich, Harlan, Alacrity
Read on below for tonight's edition of Slashback, with followups to several previous Slashdot stories, including the Linux-in-Munich saga, Harlan Ellison's feud with AOL, Hotmail's response to the growing space for webmail, and more. Read on for the details.Please don't link "here": case in point. Kent Brewster writes "As previously mentioned here(1), here(2), and here(3), national treasure Harlan Ellison has been fighting a drawn-out battle with AOL over alt.binaries.e-book. Looks like a settlement has been reached; details (such as they are) are on AOL."
Papa Legba adds a link to an informative page on the suit's progress, with lots of informative links.
The basement dwellers burrow deeper. kevin_conaway writes "Accoring to this article on Tech Target, the DNS outage at Akamai was caused by a massive DDOS attack on Akamai's servers. Akamai Technologies Inc. said a 'sophisticated, large-scale distributed denial of service attack' on its domain name service bogged down several of its clients' Web sites yesterday morning, and that it's investigating the incident with federal authorities."
Time to quit your Winin' marmoset writes "As a followup to this story, Dave Winer has posted information about transitioning weblogs.com sites. Rogers Cadenhead and Steve Kirks pitched in to help. The plan includes a 90-day free evaluation period, during which the affected users will be able to make local copies of their data, sign up for paid hosting, or move to another hosting solution."
Pay up, Pal. ack154 writes "Following up from a previous slashdot story, PayPal may have reached a preliminary settlement in the class action lawsuit brought against them in 2002. The lawsuit was regarding the freezing of suspected fraud accounts and communication of limits on accounts. Limited details are available right now, but the eBay announcement states that anyone who signed up for a PayPal account between Oct 1999 and Jan 2004 may be eligible."
Forkenbrock points to this USAToday today article which says that "Ebay's Paypal will pay a total of 9.25 million dollars to its users (businesses and individuals)."
What about Java vs. T++? Stefan de Bruijn was one of several readers who reacted to the benchmarks cited in the Slashdot post titled 'Java faster than C++'.
He writes "I took the liberty to re-write a major piece of the C++ part of the benchmark. Furthermore, the Intel compiler has been tested as well. The Java code was assumed 'correct.'
The results are quite different than the former posting. Here, C++ appears to be a winner for the vast majority of programs; where Java scored better with (recursive) algorithms and the use of file IO (where it must be remarked that the C++ code uses iostreams)." joekaylor writes "I did a similar study 6-months ago to the study sited recently here on Slashdot, and I did it with java jdk 1.4.x. Java performance has been underestimated for QUITE some time. It's not the best tool every time, but it is not considered often enough and for the wrong reasons."
And an anonymous reader writes "This article by USC graphics researchers surveys a number of good (mostly numeric) benchmarks and then explains the theory of why maybe java should be faster than C++. It also raises the (unanswered) question of why geeks (ostensibly intelligent and scientifically-minded people) continue to believe some ideas (for example, 'garbage collection is slow') despite strong evidence to the contrary that has been available for many years."
Well, it's sort of like a gigabyte. helloanand writes "So, a day after yahoo relaunched their email service with 100 MB space, hotmail also expanded their offering to 25 MB. Just logged into my hotmail account and saw the space bumped up. The thing that I noticed is that MSN/Hotmail didn't make a big splash about it. Its actually a good thing for the users. Gmail started this trend by coming up with 1 GB (yes! gigabyte) worth of space. Then yahoo joined the party with their own 100 MB version and now the latest to join in bill gates & co (aka MSN Hotmail). Lets see what other changes does Gmail stimulate to the email service. Also the thing to note is that Google's gmail is being closely observed by the established players like MSN and Yahoo."
Each city represents a star system; players alternate by country. Wudbaer writes "The Munich city council has finally OK'ed the multi-step 30 Million Euro project to migrate the Munich city council to Linux, as heise news reports (German text). The planned high-profile migration of the administration of one of the largest cities in Germany has already created a lot of interest both in pro and anti-OSS camps, and was rumored to have run into substantial problems at the beginning of the year which might have endangered the council's final OK for the project. But now apparently the road is open for the project. Go Tux !"
Marcus links to this announcement on the city government's web page, and suggests that you put it through Google.
securitas writes "Hot on the heels of Munich's decision to go with Linux, the City of Bergen, Norway will replace its Unix and Windows core infrastructure with SUSE Linux Enterprise Server 8. The second part of the implementation will migrate the city's educational network - with 100 schools and 32,000 users - from 100 Windows application servers to 20 Linux IBM eServer BladeCenters. Bergen is Norway's second-largest city. ZDNet UK's Michael Parsons discusses the choice in an interview with Bergen CTO Ole Bjoern Tuftedal."
Making less of a mess. HishamMuhammad writes "The GoboLinux story featured recently on /. got the project some publicity, but again a number of misconceptions showed up, from people who think we are "just another user-friendly distro", because of our verbose pathnames like /System/Settings. Here is an article I wrote in order to explain the principles behind the design of GoboLinux (also in PDF), which tells our side of the story."

Hosting Service Closes 3000 Blogs Without Notice
marmoset writes "Citing the high costs of running the free service, performance concerns, and health problems, Dave Winer closed down the weblogs.com hosting service without any prior notice. As many as 3000 sites are now inacessible, and the users who want to transfer their data elsewhere have to ask (politely) for it to be exported. As might be expected, reactions range from understanding to enraged. Netcraft has a report, too." -

Charles Walton, the Father of RFID
Roland Piquepaille writes "In a very interesting article, the San Jose Mercury News tells us about Charles Walton, the man behind the radio frequency identification technology (RFID). Since his first patent about it in 1973, Walton, now 83 years old, collected about $3 million from royalties coming from his patents. Unfortunately for him, his latest patent about RFID expired in the mid-1990s. So he will not make any money from the billions of RFID tags that will appear in the years to come. But he continues to invent and his latest patent about a proximity card with incorporated PIN code protection was granted in June 2004. Maybe he'll be luckier with this one. This overview contains some excerpts of the original article. It also contains tips to search for Walton's patents and an image of the front page of his first patent." -

Super Maps for the 21st Century
Roland Piquepaille writes "After five years of trials, Craig Knoblock and his team at the Information Sciences Institute of the University (ISI) of Southern California, have developed Heracles Maps, an easy-to-use laptop package to optimize routes in the whole world for both military and business travelers. This news release, "A SuperMap for Soldiers -- Or Business Travelers," says that the application integrates various sources of geospatial information, such as satellite imagery of mapping data. From this data, soldiers can easily find a safe route between two locations without being seen or shot from an enemy in another location. this package can easily be adapted to civilian applications, such as a powerful travel planner. You'll find more details and references in this overview." -
