coondoggie writes "Researchers say technology they have developed would let boats or small aquatic robots glide through the water without the need for an engine, sails or paddles. A University of Pittsburgh research team has designed a propulsion system that uses the natural surface tension that is present on the water's surface and an electric pulse to move the boat or robot, researchers said. The Pitt system has no moving parts and the low-energy electrode that emits the pulse could be powered by batteries, radio waves, or solar power, researchers said in a statement."

coondoggie sends along a NetworkWorld piece that begins, "The government... wants to motivate you to get rid of your clunker of a car for the good of the country (and the moribund car industry). A 'Cash for Clunkers' measure introduced this week by three US Senators, two Democrats and a Republican, would set up a national voucher program to encourage drivers to voluntarily trade in their older, less fuel-efficient car, truck, or SUV for a car that gets better gas mileage. Should the bill pass, the program would pay out a credit of $2,500 to $4,500 for drivers who turn in fuel-inefficient vehicles to be scrapped and purchase a more fuel-efficient vehicle."

Julie188 writes "Opera Software's year-old antitrust complaint against Microsoft took another step toward being vindicated, and the Oslo-based browser maker can't help crowing over the European Commission's decision. Opera had filed a complaint with the EC in December, 2007, contending that Microsoft's bundling of Internet Explorer with Windows violated antitrust rules. Yesterday, the EC sent a 'Statement of Objections (SO)' to Microsoft with a preliminary finding that bundling IE with Windows does indeed constitute an antitrust abuse. Microsoft has eight weeks to plead its case and change the EC's mind, an unlikely outcome if ever there was one. Opera's CEO said, 'On behalf of all Internet users, we commend the Commission for taking the next step towards restoring competition in a market that Microsoft has strangled for more than a decade.'"

coondoggie writes "How important have unmanned aircraft become to the US military? Well how's this: the Air Force says next year it will acquire more unmanned aircraft than manned. Air Force Lt. Gen. Norman Seip this week said the service is 'all in' when it comes to developing unmanned systems and aircraft. 'Next year, the Air Force will procure more unmanned aircraft than manned aircraft,' the general said. 'I think that makes a very pointed statement about our commitment to the future of [unmanned aircraft] and what it brings to the fight in meeting the requirements of combatant commanders.'"

jbrodkin writes "Wikipedia is gearing up for an explosion in digital content with new servers and storage designed to handle larger photo and video uploads. Until early 2008, the user-generated encyclopedia's primary media file server had just 2TB of total space, which was not enough to hold growing amounts of video, audio and picture files, says CTO Brian Vibber. 'For a long time, we just did not have the capacity [to handle very large media files],' he says. Wikipedia has raised media storage from 2TB to 48TB and the limit on file uploads from 20MB to 100MB. Ultimately, Wikipedia wants to eliminate any practical size limits on uploads, potentially allowing users to post feature length, high-quality videos. 'The limits will get bigger and bigger to where it will be relatively easy for someone who has a legitimate need to upload a two-hour video of good quality,' Vibber says."

Julie188 writes "Here's a new idea to stop certification test-taking cheaters; Cisco is considering introducing a verbal interview portion to its CCIE lab exams across the world. Cisco confirmed that it is running a pilot in its exam lab in Beijing, China that involves candidates taking a 10-minute verbal interview as part of their lab exam. Cisco said that if the pilot is successful, the interview could be introduced as a requirement for CCIE Routing & Switching candidates worldwide. The company has been running the pilot since August."

coondoggie writes to tell us that the FBI has issued another cracking challenge for a new cipher on their site. Tens of thousands responded to a similar challenge last year. In addition to the challenge, the FBI is also offering a few primers on the subject. There are a number of sites offering cipher challenges, but it's funny to see the FBI encouraging such behavior.

coondoggie writes "It really isn't a big enough penalty, and the company admitted no guilt, but Sony BMG Music Entertainment today agreed to pay $1 million as part of a settlement to resolve Federal Trade Commission charges that it knowingly violated the privacy rights of over 30,000 underage children. Specifically the FTC said the company violated the agency's Children's Online Privacy Protection Act (COPPA) and the FTC did say the penalty was its largest ever in a COPPA case. To provide resources to parents and their children about children's privacy in general, and social networking sites in particular, the penalty order requires Sony Music to link to certain FTC consumer education materials for the next five years."

coondoggie writes "Seven leading domain name vendors — representing more than 112 million domain names, or 65% of all registered names — have formed an industry coalition to work together to adopt DNSSEC. Members of the DNSSEC Industry Coalition include: VeriSign, which operates the .com and .net registries; NeuStar, which operates the .biz and .us registries; .info operator Afilias Limited; .edu operator EDUCAUSE; and The Public Interest Registry, which operates .org." The gTLD operators are falling in line behind government initiatives, which we discussed last month. In light of these developments, Dan Bernstein's push for DNSCurve might face an uphill slog. Reader data2 writes: "Dan Bernstein, the creator of djbdns and daemontools, has created his own proposal to improve upon the current DNS protocol. He has been opposed to DNSSEC for quite some time, and now he has proposed a concrete alternative, DNSCurve. He has posted a comparison between the two systems. His proposal makes use of elliptic curves, while DNSSEC favors RSA. He uses a curve named Curve25519, which he also developed."

coondoggie supplies an excerpt from Network World that might make you consider a lock for your pipes: "The FBI today ratcheted up the clamor to do something more substantive about the monumental growth of copper theft in the US. In a report issued today the FBI said the rising theft of the metal is threatening the critical infrastructure by targeting electrical substations, cellular towers, telephone land lines, railroads, water wells, construction sites, and vacant homes for lucrative profits. Copper thefts from these targets have increased since 2006; and they are currently disrupting the flow of electricity, telecommunications, transportation, water supply, heating, and security and emergency services, and present a risk to both public safety and national security." (A July, 2006 post on Ethan Zuckerman's blog gives an idea of how widespread cable theft has affected internet infrastructure, and basketmaking, in Africa.)

jbrodkin writes "A talking Web, solar technology embedded in windows and cell phones, and the end of forgetting will all come in the next five years, IBM predicts in its third annual Next Five in Five list, detailing innovations that could change our lives in the next half-decade. The other predictions: We will all have digital shopping assistants and, separately, 'crystal balls' to predict our future health. If IBM is right, in five years we'll forget about keyboards and use our voices to surf the Web on solar-powered laptops. DNA profiles will predict our personal health risks, and we'll get automatic reminders to perform daily tasks, generated by digital recording and analysis of our conversations."

coondoggie writes "As one of the massive flying seasons gets underway the government today took a step further in radically changing the way aircraft are tracked and moved around the country. Specifically the FAA gave the green light to deploy satellite tracking systems nationwide, replacing the current radar-based approach. The new, sometimes controversial system would let air traffic controllers track aircraft using a satellite network using a system known as Automatic Dependent Surveillance Broadcast (ADS-B), which is ten times more accurate than today's radar technology. ADS-B is part of the FAA's wide-reaching plan known as NextGen to revamp every component of the flight control system to meet future demands and avoid gridlock in the sky."

Julie188 writes "Slow-moving ocean and river currents could be a new, reliable and affordable alternative energy source. A University of Michigan engineer, Michael Bernitsas, has made a machine that works like a fish to turn potentially destructive vibrations in fluid flows into clean, renewable power. This is is the first known device that could harness energy from most of the water currents around the globe because it works in flows moving slower than 2 knots (about 2.3 miles per hour). Most of the Earth's currents are slower than 3 knots. Turbines and water mills need an average of 5 or 6 knots to operate efficiently. Further details and a few brief movies of the technology are available, as well as a video explanation by Professor Bernitsas himself."

coondoggie writes "NASA is trying to decide among eight space exploration missions that include further exploring Venus and comet composition as well landing on an asteroid or examining the space around Jupiter. The space agency today began accepting solicitations for these space exploration opportunities and will ultimately pick one of them to begin perusing in 2009 with a launch date targeted at 2018. The solicitations and ultimate expedition are part of NASA's New Frontiers program, which has as its main objective to explore the solar system with medium-class spacecraft missions that will conduct high-quality, focused scientific investigations, NASA said. The first New Frontiers mission was selected in 2003 and will result in the launch of Juno, a Jupiter polar orbiter mission set to blast off in 2011."

coondoggie writes "The Federal Trade Commission yesterday had a US District Court issue a temporary restraining order halting the sale of RemoteSpy keylogger spyware. According to the FTC's complaint, RemoteSpy spyware was sold to clients who would then secretly monitor unsuspecting consumers' computers. The defendants provided RemoteSpy clients with detailed instructions explaining how to disguise the spyware as an innocuous file, such as a photo, attached to an email."

coondoggie writes "Maybe people are more desperate or maybe there's just too much opportunity to make a quick buck but whatever the excuse, attempts to illegally export technology from the US has gone through the roof. The Department of Justice this week said it has placed criminal charges or convictions against more than 255 defendants in the past two fiscal years — 145 in 2008 and 110 in 2007. That 255 number represents more than a six-fold increase from fiscal year 2005, when the DOJ said about 40 individuals or companies were convicted of over 100 criminal violations of export control laws."

coondoggie sends this excerpt from NetworkWorld: "The US Army Research Office and the National Security Agency (NSA) are together looking for some answers to their quantum physics questions. ... The Army said quantum algorithms that are developed should focus on constructive solutions [PDF] for specific tasks, and on general methodologies for expressing and analyzing algorithms tailored to specific problems — though they didn't say what those specific tasks were ... 'Investigators should presuppose the existence of a fully functional quantum computer and consider what algorithmic tasks are particularly well suited to such a machine. A necessary component of this research will be to compare the efficiency of the quantum algorithm to the best existing classical algorithm for the same problem.'"

coondoggie sends in a Network World piece that begins "The Air Force laid out $29 million in contracts this week to build space-based sensors that could detect threats or hazards and protect satellites in orbit. Assurance Technologies and Lockheed Martin Space Systems will split $20 million of the two-year contract that the Air Force says should ultimately demonstrate a viable sensing capability, as well as integration with other space systems to offer threat and hazard detection, assessment and notification ... The Air Force is looking to protect satellites from ground based lasers or anti-satellite missiles mostly."

coondoggie writes "Nine rocket-powered vehicles will compete for NASA's $2 million, 2008 Northrop Grumman Lunar Lander Challenge, Oct. 24-25. The goal is to accelerate development of commercial Lunar Landers capable of bringing payloads or humans back and forth between lunar orbit and the lunar surface. NASA of course would expect to use some of the technology developed at the Challenge. To win the prize, teams must demonstrate a rocket-propelled vehicle and payload that takes off vertically, climbs to a defined altitude, flies for a pre-determined amount of time, and then land vertically on a target that is a fixed distance from the launch pad. After landing, the vehicle must take off again within a pre-determined time, fly for a certain amount of time and then land back on its original launch pad." Details about the teams involved with the competition are available at the X-Prize website. The event will be broadcast live via webcast next weekend.

coondoggie contributes this snippet from NetworkWorld: "You could probably see this one coming. With all of the confusion and money involved you knew there would be cyber-vultures out there looking to cash in. Well the Federal Trade Commission today issued a warning that indeed such increased phishing activities are taking place. Specifically the FTC said it was urging user caution regarding e-mails that look as if they come from a financial institution that recently acquired a consumer's bank, savings and loan, or mortgage. In many case such emails are only looking to obtain personal information — account numbers, passwords, Social Security numbers — to run up bills or commit other crimes in a consumer's name, the FTC stated."

coondoggie writes to tell us that DARPA seems to still be having fun with their funding and continues to aim for the "far out." The latest program, a submersible airplane, seems to have been pulled directly from science fiction. Hopefully this voyage to the bottom of the sea is of the non-permanent variety. "According to DARPA: 'The difficulty with developing such a craft come from the diametrically opposed requirements that exist for an airplane and a submarine. While the primary goal for airplane designers is to try and minimize weight, a submarine must be extremely heavy in order to submerge underwater. In addition, the flow conditions and the systems designed to control a submarine and an airplane are radically different, due to the order of magnitude difference in the densities of air and water.'"

coondoggie writes "Now this is some serious computer theft. We're talking 19,709 pieces of stolen computer equipment from the US Naval Research Laboratory in Washington, DC. The theft included everything from PCs and printer toner to hard drives, software and other office equipment amounting to over $120,000, according to court documents and published reports."

As hard as it is to imagine, coondoggie writes with news that the federal government just unveiled a new energy bill that will offer $15 million in assistance to retailers who help to build and adopt energy-efficient technologies. "The US Department of Energy (DOE) announced the first phase of $15 million awards to retailers Best Buy, JCPenney, John Deere, Macy's, SuperValu, Target, Toyota, and Whole Foods Market. Commercial Real Estate Firms such as CB Richard Ellis, Forest City Enterprises as well as the financials groups also saw some of the money. Along with the money the companies will have access to the DOE's Pacific Northwest National Laboratory (PNNL) and National Renewable Energy Laboratory (NREL) to design, build, tune and operate at least one new prototype building and to retrofit an existing building project."

coondoggie writes "In what may be the least astonishing news of the day, some major US companies who say they are environmentally recycling electronic waste — aren't. Rather more startling — they are dumping everything from cell phones and old computers to televisions in countries such as China and India where disposal practices are unsafe to people and dangerous to the environment. Controlling the exportation of all of the e-waste plops on the doorstep of the US Environmental Protection Agency which is doing a woeful job, according to a scathing 67-page report issued by the Government Accountability Office today."

Julie188 writes "Experts keep screaming that the IPv4 sky is falling. Three such experts were recently asked point-blank to state an irrefutable business case for moving to IPv6 now, and their answer was more plausible than the old refrain (the lack of addresses and a yet-to-be-seen killer IPv6 app). They said that there isn't a business case. No company that is satisfied with all of its Internet services will need to move, even in the next few years. They also pointed out that Microsoft is a unique position in the industry both causing and hindering IPv6 adoption — causing through its IPv6 support in its OSes, and hindering by not extending IPv6 support into very many of its apps."

coondoggie writes "The 200,000 processor core system known as Blue Waters got the green light recently as the University of Illinois at Urbana-Champaign and its National Center for Supercomputing Applications (NCSA) said it has finalized the contract with IBM to build the world's first sustained petascale computational system. Blue Waters is expected to deliver sustained performance of more than one petaflop on many real-world scientific and engineering applications. A petaflop equals about 1 quadrillion calculations per second. They will be coupled to more than a petabyte of memory and more than 10 petabytes of disk storage. All of that memory and storage will be globally addressable, meaning that processors will be able to share data from a single pool exceptionally quickly, researchers said. Blue Waters, is supported by a $208 million grant from the National Science Foundation and will come online in 2011."

coondoggie writes "The online Hitman scammer, who threatens to kill recipients if they do not pay thousands of dollars to the sender, is still sending out thousands of emails and the FBI is again today warning users to ignore the spam and report any incidents to the Internet Crime Complaint Center. Two new versions of the scheme began appearing in July 2008, the FBI said. One instructed the recipient to contact a telephone number contained in the e-mail and the other claimed the recipient or a 'loved one' was going to be kidnapped unless a ransom was paid."

Julie188 writes "A Microsoft SQL Server 2005 fan toppled over in surprise when he got this error message from SQL Server 2008 (he was running the SQL Server 2008 Upgrade Advisor tool): 'In SQL Server 2008, SQL Server native SOAP has been deprecated and will be removed in a future SQL Server release ... Avoid use of SQL server native SOAP in new development work, and plan to modify applications that currently use it.' No more SOAP-based Web services for your SQL Server database? Native XML was only added in v.2005 and was much ballyhooed at that time."

coondoggie writes "In the ongoing battle to let us eat dinner in peace without being interrupted by amazingly annoying telemarketer blather, and in this case the even more infuriating recorded telemarketing drivel, the Federal Trade Commission today basically outlawed recorded telemarketing calls. Specifically, the FTC changed its venerable Telemarketing Sales Rule (TSR) to prohibit, as of Sept. 2009, telemarketing calls that deliver prerecorded messages, unless a consumer has agreed to accept such calls from a given caller/seller. Between now and 2009, telemarketers must provide an obvious, easy and quick way for consumers to opt-out of any call, the FTC said. Such an opt-out mechanism needs to be in place by December 1, 2008."

whitehartstag writes "Black Hat 08 disclosed several SSL VPN and DNS vulnerabilities that caused several people to sit up and take notice. Some of these new exploits performed a brilliant Man-In-The-Middle attack on SSL VPN tunnels. This article walks you through how using certificates, instead of OTP tokens, for second-factor authentication can increase the security of your SSL VPN against these new types of attacks."

coondoggie brings us this NetworkWorld article, which begins: "In the ever-growing desire to produce smaller, less costly, yet more powerful and faster computers and storage devices, researchers today said they are looking at a way to use self-growing fabrics that will let manufacturers build nano-sized high resolution semiconductors and arrays to answer that craving. Researchers at the Nanoscale Science and Engineering Center (NSEC) at the University of Wisconsin — Madison have come up with a method that uses existing technology to combine the lithography techniques traditionally used to pattern microelectronics with novel self-assembling materials known as block copolymers, researchers said. When combined with a lithographically patterned surface, the block copolymers' long molecular chains spontaneously assemble into the designated arrangements."

coondoggie writes "Bigger, better, faster, more are the driving themes behind the advanced network monitoring technology BBN Technologies is building for the military. The high-tech firm got a $4.4 million contract today from the Defense Advanced Research Projects Agency (DARPA) to develop novel, scalable attack detection algorithms; a flexible and expandable architecture for implementing and deploying the algorithms; and an execution environment for traffic inspection and algorithm execution. The network monitoring system is being developed under DARPA's Scalable Network Monitoring program which seeks to bolt down network security in the face of cyber attacks that have grown more subtle and sophisticated."

jbrodkin writes "Can you trust your data to the cloud? For users of an online storage service called The Linkup, formerly known as MediaMax, the answer turned out to be a resounding 'no.' The Linkup shut down on Aug. 8 after losing access to as much as 45% of its customers' data. 'When we looked at some individual accounts, some people didn't have any files, and some people had all their files,' The Linkup CeO Steve Iverson admits. None of the affected users will get their lost data back. Iverson called it a 'worst-case scenario.'"

coondoggie writes "What do you get when you combine images from Google Earth and the brainpower from researchers at Oak Ridge National Labs? Well in this case you get a tool that enables real-time status of the national electric grid that federal state and local agencies can use to coordinate and respond to major problems such as wide-area power outages, natural disasters and other catastrophic events. The Visualizing Energy Resources Dynamically on Earth (VERDE) system, announced this week, mashes together images and stats of everything from real-time status of the electric grid and weather information to power grid behavior modeling and simulation."

coondoggie writes "The Justice Department has charged 11 people in connection with the massive theft of credit card numbers from various retailers, including TJX, BJs and OfficeMax. Authorities say the group charged was involved in the theft of more than 40 million credit and debit card numbers. In an indictment returned today by a federal grand jury in Boston, Albert 'Segvec' Gonzalez, of Miami, was charged with computer fraud, wire fraud, access device fraud, aggravated identity theft, and conspiracy for his role in the scheme. Others indicted are from the US, Estonia, China, and Belarus." We've been following the TJX breach since the beginning.

coondoggie writes "Solar race cars this week began their nine-day, 2,400 mile chase from Dallas to Calgary, Alberta using only the sun for fuel. The 24 teams in the American Solar Challenge race are mainly US college teams including entries from MIT, Ohio State and Northwestern. The University of Michigan's Continuum car is the defending champ, having won the Challenge in Australia last year. The University of Michigan has won four out of the eight North American Solar Challenges it has entered with its team of more than 100 engineering students, who have vowed to defend their title this year."

coondoggie writes to tell us that in a recent report to Congress by the FTC, the National Do Not Call Registry got glowing reviews. They seem to be well established now with $21 million in fees in the bank, 22 successful court cases, and an almost 70% approval rating. "In 2007, a total of 6,242 entities paid fees totaling $21,602,003 for access to the National Registry. According to the FTC, telemarketers and sellers can access registered telephone numbers and pay the appropriate fee for that access, if any, through an Internet website dedicated to that purpose. The only information about consumers that companies receive from the National Registry is the registered telephone number. Since the Registry's inception, a total of 18,197 unique entities have paid fees for access to the National Registry. The total amount of fees paid by all entities since the inception of the National Registry through the end of 2007 is $80,629,778, the report stated."

coondoggie writes "In an effort to buttress its enforcement and better understand the scourge that is identity theft, the Federal Trade Commission said today its plans to conduct a wide-ranging study of victims of the crime. The FTC is looking for people harmed by the crime and said the survey will examine the remedies available to victims under the Fair and Accurate Credit Transactions Act of 2003 (FACT Act). Among other things, the FACT Act gave consumers the right to place fraud alerts on their credit files if they are, or suspect they may become, victims of identity theft; block information on their credit reports that resulted from identity theft; and obtain copies of their credit reports free of charge."

coondoggie writes "The National Science Foundation (NSF) reissued the words that started the Internet revolution 20 years ago today: 'The NSFnet Backbone has reached a state where we would like to more officially let operational traffic on.' That was the email sent to users of the NSF's fledgling NSFnet to announce that the network's backbone had been upgraded to a 'blazing T-1 speed.' NSFnet was created by NSF a few years earlier in an attempt to create a computer network similar to the Department of Defense's ARPANET. When the original six-node, 56 kilobits-per-second NSFnet backbone went into operation in 1986, NSF made the decision to allow any academic, governmental or commercial entity to hook up to this network of networks. Within a few weeks of going online, traffic on the new network began doubling every few weeks. The network's backbone of core 56 kilobits-per-second connections were considered fast, but they were not fast enough to satisfy the demands of all the new users who were coming online, according to the NSF."

coondoggie writes "Canadian scientists are developing a 143-lb microsatellite to detect and track near-earth asteroids and comets, as well as satellites and space junk. The suitcase-sized Near Earth Object Surveillance Satellite includes a 6-inch diameter telescope, smaller than most amateur astronomers' scopes, that by being located 435 miles above the Earth's atmosphere will be able to detect moving asteroids delivering as few as 50 photons of light in a 100-second exposure. The NEOSSat will twist and turn hundreds of times each day, orbiting from pole to pole every 50 minutes, almost always in sunlight. The telescope has a sunshade that allows searching the sky to within 45 degrees of the Sun, in order to detect near-Earth asteroids whose orbits are entirely inside Earth's." The probe was announced a few days before the 100th anniversary of the Tunguska blast.

coondoggie writes "A researcher has discovered a way to use facial expressions to speed and slow video playback. By using a combination of facial expression recognition software and automated tutoring technology Jacob Whitehill, a computer science Ph.D. student from UC San Diego's Jacobs School of Engineering, is leading the project that ultimately is part of a larger venture to use automated facial expression recognition to make robots more effective teachers. The researchers recently conducted a pilot test with 8 people that demonstrated information within the facial expressions people make while watching recorded video lectures can be used to predict a person's preferred viewing speed of the video and how difficult a person perceives the lecture at each moment in time."

coondoggie writes "A US District Court today ordered a halt to the illegal practice of Canadian companies who the Federal Trade Commission said deceptively posed as domain name registrars and sent bogus bills to thousands of US small businesses and nonprofit organizations for their annual 'Website Address Listing.' The FTC said many of the businesses believed they would lose their Web site addresses unless they paid the bill, so they paid but in most cases the defendants did not provide domain registration services, did not provide the 'search optimization' services it claimed to provide, and bilked small businesses and nonprofits out of millions of dollars."

coondoggie writes "Google largely conquered the Earth — now it is taking aim at space. At least co-founder Sergei Brin is. Brin today said he put down $5 million toward a flight to the International Space Station in 2011. Brin's space travel will be brokered by Space Adventures, the space outfit that sent billionaire software developer Charles Simonyi to the station in 2007. Computer game developer (and son of a former NASA astronaut) Richard Garriott is currently planning a mission to the ISS in October 2008. Garriott is paying at least $30 million to launch toward the space station aboard a Russian Soyuz spaceship according to Space Adventures." Make sure to wave when you are over Michigan, man. I'll be the one on my lawn, green with envy.

coondoggie writes "Can Internet worms be thwarted within minutes of their infection? Researchers at Ohio State University believe they can. The key, researchers found, is for software to monitor the number of scans that machines on a network send out. When a machine starts sending out too many scans — a sign that it has been infected — administrators should take it off line and check it for viruses. In a nutshell, the researchers developed a model that calculated the probability that a virus would spread, depending on the maximum number of scans allowed before a machine was taken off line.'The difficulty was figuring out how many scans were too many,' researchers said."

coondoggie writes to mention that Duke University researchers have created micro-robots and made them dance to their tune. With dimensions measured in microns, these tiny bots were made to waltz to the music of Strauss on the head of a pin just one millimeter across. "In another sequence, the devices pivot in a precise fashion whenever their boom-like steering arms are drawn down to the surface by an electric charge. This response resembles the way dirt bikers turn by extending a boot heel, researchers said. The researchers said they have also been able to get five of the devices to group-maneuver in cooperation under the same control system.Known as microelectromechanical system (MEMS) microrobots, the devices are of suitable scale for Lilliputian tasks such as moving around the interiors of laboratories-on-a-chip."

coondoggie brings us a Networkworld report detailing NASA's selection of six mission proposals for further study by the Small Explorer (SMEX) Program. The goal of the program is to develop cheap, tightly focused science missions (PDF). Among the selected proposals are a satellite telescope bank for use in detecting exoplanets, and a solar coronograph which will study solar wind and coronal ejections. Networkworld provided links with more detailed information on most of the projects.

Roland Piquepaille writes "It's now almost certain that the world's ice shelves are melting. And while satellites provide lots of data about their evolution, ground-based weather stations could be even more useful. But if scientists can no longer stay on fragile and volatile ice sheets, what can they do? They can use specially designed robots called SnoMotes developed by U.S. researchers. 'The SnoMotes work as a team, autonomously collaborating among themselves to cover all the necessary ground to gather assigned scientific measurements.' More importantly, a SnoMote is an 'expendable rover that wouldn't break a research team's bank if it were lost during an experiment,' according to the lead researcher." Reader coondoggie adds a link to another story on these robots at Network World.

coondoggie writes "Until today, most Internet-based real-estate brokers were considered second-class citizens, and their clients were left in the cold. But perhaps that will change with today's news that the Department of Justice has reached a proposed settlement with the National Association of Realtors that requires NAR to let Internet-based residential real estate brokers compete with traditional brokers. NAR has agreed to be bound by a 10-year settlement, under whose terms NAR will repeal its anticompetitive policies and require affiliated multiple listing services to repeal their rules that were based on these policies." Here's the whole settlement document on the DoJ's site.

Julie188 writes "Governments are turning the Internet into a cyberspace reflection of real-world geographic conflicts. One report says that the Canadian government is forbidding its IT organizations to use services that store or host the government's data outside their sovereign territory. They especially cannot use services where the data is stored in the United States because of fears over the Patriot Act. What kinds of jurisdiction issues might people face — think Google cooperating with the Chinese government — as cloud computing becomes the norm and your data is stored in 'offshore parts' of the cloud?"

coondoggie links to a Network World story about myriad security flaws (described in a report from the Governmental Accountability Office) at all levels of the Tennessee Valley Authority, the country's largest public power utility, excerpting: "The Tennessee Valley Authority (TVA) is a federal corporation that generates power using 52 fossil, hydro and nuclear facilities in an area of about 80,000 square miles and has not fully implemented appropriate security practices to protect the control systems used to operate its critical infrastructures, the GAO concluded. TVA's corporate network infrastructure and its control systems networks and devices at individual facilities and plants reviewed were vulnerable to disruptions that could endanger a good portion of the country's economic security and public health and safety, the GAO said." The TVA is hardly alone, though, when it comes to governmental computer security. Reader bc90021 points out the Federal Government's newly released Computer Security Report Card (prepared for Congressman Tom Davis), which "breaks down the agencies and assigns them all a grade. There are plenty of Fs, not the least of which is for the newly reconnected Department of the Interior."
