With NASA’s manned space flight program in tumult, it’s an open question when/if human boots will tramp on Martian soil. But the space agency has provided a virtual way for humans to explore the red planet, with its new “Be a Martian” program.

The online project, a collaboration between NASA and Microsoft, enlists the power of crowdsourcing. Users are invited to sort through the hundreds of thousands of photos of Mars that have been sent back by rovers and orbiters. To convince people to spend hours pouring over pictures of dusty Martian landscapes, two tasks have been set up as games where participants can win points and badges. One game asks people to count craters in photos of Mars; the other asks people to match small, high-res photos of the Martian surface with their corresponding locations on a low-res photo taken from a higher altitude [Seattle Post-Intelligencer]. (You’ll need to have Microsoft’s Silverlight application for the games and videos on the site to work.)

By enlisting citizen scientists, NASA hopes to both interest students in space careers and to make real progress in Martian research. “We really need the next generation of explorers,” says Michelle Viotti, from the agency’s Jet Propulsion Laboratory, which oversees Mars missions. “And we’re also accomplishing something important for Nasa. There’s so much data coming back from Mars. Having a wider crowd look at the data, classify it and help understand its meaning is very important” [BBC News].

The self-proclaimed spam king of the Internet, Sam “Spamford” Wallace, was ordered to pay Facebook $711 million in civil damages for slinging spam on the social networking site. Wallace allegedly accessed Facebook accounts without obtaining permission, and used them to make bogus wall posts and spam the account holders’ friends. Those actions run afoul of the CAN-SPAM Act of 2003, which sets guidelines for commercial e-mails, which are enforced by the Federal Trade Commission (FTC) [PC World]. The judge also referred Wallace to the U.S. Attorney’s Office with a request that he be prosecuted for criminal contempt, which means he could actually face jail time if convicted.

If you’ve ever received an unsolicited email (and who hasn’t), chances are good that it came from Wallace’s company, Cyber Promotions, which was once the largest source of spam. So not surprisingly, this isn’t the first time Spamford has run afoul of the law. In May, 2008, MySpace won a $230 million judgment against Wallace for sending junk messages. Wallace was also fined $4 million by the Federal Trade Commission in 2006 for his excessive pop-up ads [CNN]. Officials at Facebook said they don’t expect to see much of the $711 million, seeing as how Wallace is bankrupt and may soon have to send out his spam as hand written letters from behind bars.

Yes, in early September we sent the Internet our birthday best wishes, noting that it had been 40 years since computer scientists at the University of California, Los Angeles connected two computers via a 15-foot cable, allowing for the transmission of data between them. But it wasn’t until October 29, 1969 that the first message passed between two different computer nodes, one at UCLA and the other at Stanford University. The message that researcher Leonard Kleinrock intended to send to Stanford was “login” but Kleinrock was only able to type “lo” before the system crashed. On his second attempt, the message went through successfully [ABC News]. With that, a net was born.

The system dubbed ARPANET, which was funded by the U.S. Department of Defense, would lead directly to the Internet that we know, love, despise, and rely on utterly today. To date, over 1 billion people are online, and last year, Google announced that it had detected over 1 trillion pages [PC World].

Vinton Cerf, an Internet pioneer and the current Chief Internet Evangelist at Google says the online world will continue to evolve in ways we can barely imagine, but which serve humanity’s basic drive to communicate. “Don’t let anyone tell you that information is power…. It’s information-sharing that’s power” [LiveScience], he says.

Three scientists who mastered light through technology have been awarded this year’s Nobel Prize for physics, for breakthroughs that the prize committee said “helped to shape the foundations of today’s networked societies.” Half of the $1.4 million prize goes to Charles Kao (pictured), for his work on fiber optics, while the other half will be divided between Willard Boyle and George Smith, two retired researchers from Bell Labs who invented the first imaging technology using a digital sensor instead of film, paving the way for the creation of digital cameras.

Kao’s discovery in fiber optics set the stage for the technological revolution that underpins today’s global communication systems, powering broadband internet connections and carrying data transmissions around the world. In 1966, he figured out how to transmit light for more than 100 kilometers using optical glass fibers, five times the length of the most advanced fibers then available [Bloomberg]. Fiber optics have become ubiquitous in today’s wired, networked world; the Nobel committee noted that if all the optical cables in use today were unraveled, it would equal a single thread more than a billion kilometers long, enough to circle the globe 25,000 times.

Looking for an easy, cheap way to spy on your neighbors? Researchers are working on a device that may be just the thing, which uses a simple wireless network to “see” through a wall and detect people moving around in the room beyond. But paranoid apartment-dwellers will be glad to know that the system still has plenty of limitations. At the moment the system can only track movement within a three-foot range, and it can only sense motion–it can’t put together a picture of what or who’s moving.

The system relies on the variations of radio signals in a wireless network. The signal strength at any point in a network is the sum of all the paths the radio waves can take to get to the receiver. Any change in the volume of space through which the signals pass, for example caused by the movement of a person, makes the signal strength vary. So by “interrogating” this volume of space with many signals, picked up by multiple receivers, it is possible to build up a picture of the movement within it [Technology Review]. The paper describing the technology has been posted on the arXiv pre-print server, and has not yet been peer-reviewed.

The device could be more than a boon for voyeurs or robbers. The researchers argue that the technology could be used in search and rescue operations, with emergency teams using the same radio technology used by Wi-Fi networks to build a web of sensors around a disaster site, revealing the location of victims and survivors [Telegraph].

It may not look a day over 35, but the Internet turned 40 years old today. On September 2, 1969, computer scientists at the University of California, Los Angeles, hooked up two computers via a 15-foot cable, allowing them to exchange data. It marked a milestone in the creation of the Advanced Research Projects Agency Network, or ARPANET, which later gave rise to the Internet.

Still, it wasn’t until October 29 of the same year that the first message was sent between computer nodes; for that reason, some say the Internet was really born at the end of October. In any case, the Internet has come a long way since 1969: The first message was supposed to be “login” but [computer scientist Leonard] Kleinrock was only able to type “lo” before the system crashed [ABC News]. Now, life without the Web seems almost unimaginable (especially to these bloggers!). It’s impossible to get your brain around all that the Internet is and what is has done for us these 40 years. Luckily, the Internet is organized in such a way that we don’t have to [NPR].

Every time you go online, your privacy is at stake. As you surf Web sites and enter search terms, large Internet companies and ad networks are collecting data about you, your hobbies, your habits, and your purchases in order to figure out which ads to display for you next. The companies argue that this practice, known as behavioral advertising, produces ads that are far more relevant to users than simply spamming them with whatever is selling that week, but privacy advocates are concerned about the amount of data that is being collected and what might be happening with that data behind the scenes [CNET].

Earlier this year a congressional committee held hearings on the topic, and asked for input from privacy groups. On Tuesday, representatives from a range of privacy and consumer protection groups asked the House Commerce Committee to prohibit online marketers from collecting sensitive data, require them to inform users what the data is being collected for and give individuals the right to see data collected about them [Wired.com]. U.S. Representative Rick Boucher of Virginia is expected to introduce a privacy bill this fall, and privacy advocates are hopeful that he’ll incorporate their ideas.

The off-limits “sensitive data” could include information about an Internet user’s race, political activity, and sexual orientation, as well as medical and financial data. The privacy groups also said in their recommendations (pdf) that data should not be collected from any user under the age of 18, if age could be determined. They also suggest that Web sites and advertisers only retain behavioral data for 24 hours, after which they must receive consent from users or get rid of it [The Wall Street Journal], in what amounts to an “opt-in” system for consumers.

A 28-year-old hacker has been charged in what federal prosecutors are calling the largest case of identity theft ever seen. The man, Albert Gonzalez, worked with two unnamed Russian conspirators to run wild through the computer networks of a handful of prominent corporations, including 7-Eleven, the supermarket chain Hannaford Brothers, and the payment processor Heartland Payment Center. The size of the heist—130 million credit and debit card numbers, according to prosecutors—have many people wondering: How exactly is such a massive theft carried out?

The Justice Department’s indictment (pdf) describes how Gonzales (a.k.a. “segvec” and “soupnazi,” among other aliases) and his co-conspirators pulled it off. They began the job by scanning lists of Fortune 500 companies for likely targets, and then visited retail outlets to scope out the payment systems used at checkout counters and to look for vulnerabilities. Then they would write specific codes to corrupt their data systems and launch a virus from computers in the United States and Europe to pull hundreds and thousands of credit card numbers, and sort through them using a “sniffer,” which is basically a data analysis system that decodes big chunks of information [The Atlantic].

The cyber-attack that temporarily disabled Twitter and compromised Facebook and LiveJournal was politically motivated and was directed at a pro-Georgian blogger called Cyxymu, says a representative from Facebook.

The attack, which paralyzed Twitter for two hours and “degraded” service on Facebook, was one known as a distributed denial of service attack. This technique uses a network of tens of thousands of compromised computers, known as a “botnet”, to flood a website’s servers with page view requests, leaving legitimate traffic unable to get through. This huge amount of connection requests can quickly overwhelm a server and, in some cases, cause an entire website to crash [Telegraph]. It seems Twitter, a relatively new service with a U.S.-based infrastructure, couldn’t handle the surge in traffic, while Facebook and Google, which have many key services located internationally, were better-prepared for it.

It has not been confirmed who perpetrated the attack, but the blogger says he believes it could have been an attempt by the Russian government to squelch his criticism of over Russia’s conduct in the war over the disputed South Ossetia region, which began a year ago today. “Maybe it was carried out by ordinary hackers but I’m certain the order came from the Russian government” [Guardian], the blogger said. Such a widespread attack, some believe, would only be possible if the coordinator of the attack had access to significant resources.

Evaluating the happiness of an entire society is tricky–after all, the traditional survey-based method of collecting data doesn’t work for such a huge population. But now scientists say they have come up with a way to quantify the well-being of a society: by analyzing song lyrics and blog posts for emotionally charged words, according to a study published in the Journal of Happiness Studies. Among their findings, researchers determined that bloggers in their 50s and 60s are most content, and that popular music has become increasingly less happy since the 1960s.

To evaluate the overall happiness of the public, researchers pulled data from nearly two-and-a-half million blogs and 230,000 song lyrics. With the aid of their own computers, the researchers scanned the texts for more than 1000 emotionally charged words that a 1999 psychology study had ranked on a scale from 1 (miserable) to 9 (ecstatic). “Triumphant” and “love” topped the list with average scores greater than 8.7, whereas “disgusted” was one of the lowest at 2.45. The researchers then calculated an average happiness score for each text based on the words’ scores and frequencies [ScienceNOW Daily News]. They found that although certain days of the year always show fluctuations in the blog world (Christmas and Valentine’s Day show a spike in happiness, while September 11 shows a dip in well-being), overall happiness among the bloggers since 2005 has increased about 4 percent.

Volunteers helping astronomers classify galaxies in an online project have identified an entirely new type of galaxy, which they dubbed “green pea” galaxies due to their resemblance to little green legumes floating in space. The citizen scientists who had noticed the oddities, and who came to call themselves the “Pea Corps” and the “Peas Brigade,” began to discuss the phenomena on an online forum, and soon enough professional astronomers with links to the project confirmed that the volunteers had found a never-before-seen type of galaxy.

Says astronomer Carolin Cardamone: “No one person could have done this on their own…. Even if we had managed to look through 10,000 of these images, we would have only come across a few Green Peas and wouldn’t have recognized them as a unique class of galaxies.” Of the one million galaxies that make up the image bank, the researchers found only 250 Green Peas [SPACE.com]. Cardamone and her colleagues wrote up the results, which will be published in the Monthly Notices of the Royal Astronomical Society.

A French hacker broke into the email accounts of Twitter executives and employees, and now the cyber snoop is leaking business and personal info about company leaders to TechCrunch, an American blog, and Korben, a French blog. The hacker reportedly guessed passwords and gained access to several Gmail accounts, as well as accounts with Google Docs, PayPal, and other services.

TechCrunch received a compressed zip file of 310 confidential documents, including a complete Twitter employee list and salary information; food preferences of Twitter employees; confidential contracts with companies such as Nokia, Samsung, Dell, AOL, Microsoft, and others; a contact list of notable Web and entertainment personalities; meeting reports; [and] applicant resumes [PC World]. Now it’s up to the site to decide what information to publish. Thus far, TechCrunch has decided not to release anything that is personally embarrassing. Still, under the philosophy “News is what somebody somewhere wants to suppress; all the rest is advertising,” the site will release documents it considers relevant to the company. These include notes from executive meetings, the original pitch for a Twitter TV show, and certain company financial information.

The Chinese government has banned the controversial use of electroconvulsive therapy, or shock therapy, to treat the controversial diagnosis of “Internet addiction.” With an estimated 300 million Internet users, China has been grappling with how to keep avid Web surfers from spending their whole lives online, and various clinics have sprung up, offering parents the chance to “cure” their children of the uncontrollable urge to blog or play online games [Telegraph]. But a recent scandal involving a psychiatric hospital in Shandong province that was using a “brain-waking” treatment of electric shocks has rallied public opinion against such clinics.

China’s Ministry of Health has now posted a notice on its Web site stating that there is no evidence that electric shock therapy is an effective treatment for Internet addiction. A hospital spokeswoman last week said “sensationalized” media reports had already led it to cease the shock treatment. The shocks were meant to cause subjects to associate a negative result with Internet use, according to the hospital [ComputerWorld]. People who were subjected to the treatment report that they were forced to apologize for and repudiate their Internet-using ways while receiving the shocks, which were also used as punishment for uncooperative behavior. In what might be an indication of the clinic’s effectiveness, its practices came to light when former patients went online to complain [The Wall Street Journal].

The first permanent node of the “interplanetary internet” has been installed and tested out aboard the International Space Station, in what NASA officials say is the first step to a communication system that could one day span the solar system. The interplanetary internet got its first deep space tryout last fall, when a spacecraft called EPOXI that’s on its way to a comet rendezvous used the system to send images back to its controllers on Earth. Now, researchers are ready to test it out in regular communications with the space station.

There’s a fringe benefit: In just a few months, astronauts will be able to tweet live from the international space station. “NASA is trying to leverage the popularity of Twitter to get its message out,” said [researcher] Kevin Gifford…. “To tweet from space will have a lot of glitz value” [Denver Post]. Currently, astronauts on the space station have to schedule times to send or receive data from mission control below; that’s why the first astronaut to make use of Twitter on a space shuttle flight, Mike Massimino, aka @Astro_Mike, had to send his tweets to Houston and have a NASA employee post them to his profile.

Were you born after 1988 in a small state? If so, researchers would have a particularly good chance of figuring out your Social Security number. In a new study, researchers used publicly available data, including an individual’s place and date of birth, to guess the Social Security number that would have been assigned to that person. And the study’s authors say that cyber-crooks could use similar techniques for identity theft. “We live in a precarious time, where knowledge of a Social Security number, along with other information about one’s name and date of birth, is sometimes sufficient to impersonate another individual,” said Alessandro Acquisti, the study’s lead author [Bloomberg].

Acquisti’s team shared their results with the federal government, but the Social Security office is downplaying the findings; spokesman Mark Lassiter said there is still no “foolproof” method for predicting Social Security numbers. “The suggestion that Mr. Acquisti has cracked a code for predicting an SSN is a dramatic exaggeration,” Lassiter said via e-mail. However, he added: “For reasons unrelated to this report, the agency has been developing a system to randomly assign SSNs. This system will be in place next year” [AP].
