An anonymous reader sends us to the NYTimes for a sobering look at the frontiers of "collective intelligence," also called in the article "reality mining." These techniques go several steps beyond the pedestrian version of "data mining" with which the Pentagon and/or DHS have been flirting. The article profiles projects at MIT, UCLA, Google, and elsewhere in networked sensor research and other forms of collective intelligence. "About 100 students at MIT agreed to completely give away their privacy to get a free smartphone. 'Now, when he dials another student, researchers know. When he sends an e-mail or text message, they also know. When he listens to music, they know the song. Every moment he has his Windows Mobile smartphone with him, they know where he is, and who's nearby.' ... Indeed, some collective-intelligence researchers argue that strong concerns about privacy rights are a relatively recent phenomenon in human history. ... 'For most of human history, people have lived in small tribes where everything they did was known by everyone they knew,' Dr. Malone said. 'In some sense we're becoming a global village. Privacy may turn out to have become an anomaly.'"

Aviran was one of many readers to submit news of a just-announced development in the ongoing quest to develop a working invisibility cloak, writing: "Scientists say they are a step closer to developing materials that could render people and objects invisible. Researchers have demonstrated for the first time they were able to cloak three-dimensional objects using artificially engineered materials that redirect light around the objects. Previously, they only have been able to cloak very thin two-dimensional objects" Reader bensafrickingenius adds a link to coverage at the Times Online, and notes that "the world's two leading scientific journals, Science and Nature, are expected to report the results this week." Tjeerd adds a link to a Reuters' story carried by Scientific American.

Bibek Paudel brings us a BBC report on the development and testing of an new ion engine by a security firm named Qinetiq. The engine will be used in an ESA spacecraft tasked with mapping the Earth's gravitational field from orbit. Only a handful of ion drives have been used for space missions before, some of which we have discussed. Quoting: "Cryogenic pumps can be heard in the background, whistling away like tiny steam engines. Using helium gas as a coolant, they can bring down the temperature in the vacuum chamber to an incredibly chilly 20 Kelvin (-253C). The pressure, meanwhile, can drop to a millionth of an atmosphere. Ion engines ... make use of the fact that a current flowing across a magnetic field creates an electric field directed sideways to the current. This is used to accelerate a beam of ions (charged atoms) of xenon away from the spacecraft, thereby providing thrust."

coondoggie writes to tell us that researchers from Penn State and New Mexico Tech have unraveled the mystery of lightning diversity. A new "Lightning Mapping Array" has been able to show detailed models on how lightning acts. "About 90% of lightning occurs inside clouds and is not visible to the casual observer, researchers said. The researchers wondered if lightning that appears within clouds and the lightning that escapes upward or downward shared the same development mechanisms, researchers said. Lightning forms in clouds when different areas of the cloud become either positively or negatively charged. Once the electric field near a charged area exceeds a certain propagation level, lightning occurs. The type of lightning depends on where the charge builds and where the imbalance in charge exists in the clouds. The mechanism behind different types of lightning is what the new model shows, researchers said."

Amit Agarwal writes "Adobe today launched a basic version of Adobe Photoshop available for free online. Photoshop Express will be completely Web-based so consumers can use it with any type of computer, operating system and browser. According to Yahoo! News, Adobe says providing Photoshop Express for free is part marketing and part a strategy to create up-sell opportunities. It hopes some customers will move from it to boxed software like its $99 Photoshop Elements or to a subscription-based version of Express that's in the works."

climber writes "Just days after the first scareware for OSX, researchers are pondering the problems of an iPhone exploit that could lead to larger issues. The Trojan pulls legitimate apps off the phone if you try to remove it, but it only infects iPhones that have 'been modified or opened through a security hole in the system.' Though this worm is more of an annoyance than anything else, it could be a proof of concept for a more serious attack. 'The fear is hackers may be experimenting and gathering research that will increase the dangers of a more malicious attack in the near future. It is clear at least one writer -- the author of this piece at Web Worker Daily -- thinks that the iPhone should be left on the dresser in the morning. She offers several reasons that the device isn't a good corporate tool.'"

Komi writes "Has anyone tackled the Traveling Salesman Problem with Google Maps or any other online mapping tool? I've searched, but can't find anything. To me this seems like such an obviously cool function. I'm not up to date on algorithms, so perhaps this isn't really tractable for large values of n. But for small numbers (maybe up to 5), this could at least be brute-forced. I would love to use this when I have errands to run, and I want an overall optimal route. So if this hasn't been done, someone please do it!"

Riding with Robots writes "No, it's not an accident due to a metric-to-English-units error. In February, the New Horizons probe passed through the Jupiter system on its way to Pluto, and we saw some spectacular pictures. Now, the science teams have published detailed scientific results, along with new images and movies. The probe's instruments saw clouds form from ammonia welling up from Jupiter's lower atmosphere, and heat-induced lighting strikes in the polar regions, and fresh eruptions on the volcanic moon Io. New Horizons also captured the clearest images ever of the tenuous Jovian ring system, where scientists spotted clumps of debris that may indicate a recent impact inside the rings, or some more exotic phenomenon." I bet Neil DeGrasse Tyson will be on 7 Discovery channel specials talking about these new discoveries inside of the week. Hope he's nicer than he was to poor Pluto :)

iminplaya writes "The UK government can now demand that citizens hand over their data encryption keys - or face jailtime for obstructing justice. The law only applies to data on UK shores, and doesn't cover information transmitted via UK servers across the internet. 'The law also allows authorities to compel individuals targeted in such investigation to keep silent about their role in decrypting data ... The Home Office has steadfastly proclaimed that the law is aimed at catching terrorists, pedophiles, and hardened criminals--all parties which the UK government contends are rather adept at using encryption to cover up their activities.'"

jcaruso writes, "It's been more than 100 years since the discovery of the 2,000-year-old Antikythera Mechanism, but researchers are only now figuring out how it works." From the article: "Since its discovery in 1902, the Antikythera Mechanism — with its intricate and baffling system of about 30 geared wheels — has been an enigma... During the last 50 years, researchers have identified various astronomical and calendar functions, including gears that mimic the movement of the sun and moon. But it has taken some of the most advanced technology of the 21st century to decipher during the past year the most advanced technology of the 1st century B.C."

The_Slaughter writes "The MPAA has recruited the boy scouts of America to do their dirty work. Scouts will now be able to learn a merit badge for anti-piracy related activities, including creating public service announcements urging others not to steal movies or music. No word yet on if that includes helping the MPAA file lawsuits against 80-year-old grandmothers."

bartv writes "Blender 2.42 has been released. It features an impressive list of new features for professional users. The most important improvements are: a new render pipeline, node editors for compositing and materials, support for anisotropic materials, improved fluid simulation and new character animation tools. Most of these features are the result of the production of Elephants Dream, the first Open Movie. During this project, Blender's lead developer Ton Roosendaal was coding the features that were required by the artists to produce their movie."
