writes "Iapetus, Saturn's third largest moon, was first photographed by the Cassini spacecraft on 31 December 2004. The images created something of a stir. Clearly visible was a narrow, steep ridge of mountains that stretch almost halfway around the moon's equator. The question that has since puzzled astronomers is how this mountain range got there. Now evidence is mounting that this mountain range is not the result of tectonic or volcanic activity, like mountain ranges on other planets. Instead, astronomers are increasingly convinced that this mountain range fell from space. The latest evidence is a study of the shape of the mountains using 3-D images generated from Cassini data. They show that the angle of the mountainsides is close to the angle of repose, that's the greatest angle that a granular material can form before it landslides. That's not proof but it certainly consistent with this exotic formation theory. So how might this have happened?
Astronomers think that early in its life, Iapetus must have been hit by another moon, sending huge volumes of ejecta into orbit. Some of this condensed into a new moon that escaped into space. However, the rest formed an unstable ring that gradually spiraled in towards the moon, eventually depositing the material in a narrow ridge around the equator. Cassini's next encounter with Iapetus will be in 2015 which should give astronomers another chance to study the strangest mountain range in the Solar System."Read Replies (0)

writes "While we are still waiting for the official Windows 8.1 touch-enabled apps to get launched on the Windows Store, Microsoft went and decided that it's time to finally bring the Office online apps to the Chrome Web Store, instead. Thus, Microsoft is making the Web versions of its Word, Excel, PowerPoint and OneNote apps available to users through the Chrome Web Store and also improving all of them with new features, along with several bug fixes and performance improvements."
More on the Microsoft front: an anonymous reader wrote in with a link to Ars Technica's review of the upcoming Windows Phone 8.1 release
: "It is a major platform update even if it is just a .1 release. Updates include the debut of Cortana, using the same kernel as Windows 8.1 and the Xbox One, a notebook reminder app, inner circle friend management, IE 11, Nokia's camera app by default, lock screen and background customizations, a much improved email client with calendar support, more general Windows 8.1 API inclusion for better portability, and a notification center. Ars rated it more of a Windows Phone 9 release than .1 update."Read Replies (0)

writes "In his yet-to-be-released book, Six Amendments: How and Why We Should Change the Constitution, John Paul Stevens, who served as an associate justice of the Supreme Court for 35 years, believes he has the key to stopping the seeming recent spate of mass killings — amend the Constitution to exclude private citizens from armament ownership. Specifically, he recommends adding 5 words to the 2nd Amendment, so that it would read as follows: 'A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms when serving in the Militia shall not be infringed.'
What I find interesting is how Stevens maintains that the Amendment only protects armament ownership for those actively serving in a state or federal military unit, in spite of the fact that the Amendment specifically names 'the People' as a benefactor (just like the First, Fourth, Ninth, and Tenth) and of course, ignoring the traditional definition of the term militia. I'm personally curious about his other 5 suggested changes, but I guess we'll have to wait until the end of April to find out."Read Replies (0)

Eben Moglen's FreedomBox
concept (personal servers for everyone to enable private communication) is getting closer to being an easy-to-install reality: all packages needed for FreedomBox are now in Debian
's unstable branch, and should be migrating to testing in a week or two. Quoting Petter Reinholdtsen: "Today, the last of the packages currently used by the project to created the system images were accepted into Debian Unstable. It was the freedombox-setup package, which is used to configure the images during build and on the first boot. Now all one need to get going is the build code from the freedom-maker git repository and packages from Debian. And once the freedombox-setup package enter testing, we can build everything directly from Debian. :)
Some key packages used by Freedombox are freedombox-setup, plinth, pagekite, tor, privoxy, owncloud, and dnsmasq. There are plans to integrate more packages into the setup. User documentation is maintained on the Debian wiki."
You can create your own image with only three commands, at least if you have a DreamPlug or Raspberry Pi (you could also help port it to other platforms

writes "As Google Glass goes on sale [ed: or rather, went on sale] to the general public, GeekWire reports that Bill Gates has already snagged one patent for 'detecting and responding to an intruding camera' and has another in the works. The invention proposes to equip computer and device displays with technology for detecting and responding to any cameras in the vicinity by editing or blurring the content on the screen, or alerting the user to the presence of the camera. Gates and Nathan Myhrvold are among the 16 co-inventors of the so-called Unauthorized Viewer Detection System and Method, which the patent application notes is useful 'while a user is taking public transportation, where intruding cameras are likely to be present.' So, is Bill's patent muse none other than NYC subway rider Sergey Brin?"

writes "Jonathan Kaiman reports at The Guardian that China's air pollution could be intensifying storms over the Pacific Ocean and altering weather patterns in North America leading to more ... warm air in the mid-Pacific moving towards the north pole. 'Mid-latitude storms develop off Asia and they track across the Pacific, coming in to the west coast of the U.S.,' says Ellie Highwood, a climate physicist at the University of Reading. 'The particles in this model are affecting how strong those storms are, how dense the clouds are, and how much rainfall comes out of those storms.' Fossil fuel burning and petrochemical processing in Asia's rapidly developing economies lead to a build-up of aerosols, fine particles suspended in the air. Typically, aerosol formation is thought of as the antithesis to global warming: it cools our Earth's climate. But researchers say, too much of any one thing is never good. 'Aerosols provide seeds for cloud formation. If you provide too many seeds, then you fundamentally change cloud patterns and storm patterns,' says co-author Renyi Zhang. China's leaders are aware of the extent of the problem and will soon revise China's environmental protection law for the first time since 1989 ... 'The provisions on transparency are probably the most positive step forward,' says Alex Wang, expert in Chinese environmental law at UCLA. 'These include the requirement that key polluters disclose real-time pollution data.'"Read Replies (0)

An anonymous reader tips news of an incident in a Pennsylvania high school in which a student, Christian Stanfield, was being bullied on a regular basis. He used a tablet to make an audio recording of the bullies for the purpose of showing his mother how bad it was. She was shocked, and she called school officials to tell them what was going on. The officials brought in a police lieutenant — but not to deal with the bullies. Instead, the officer interrogated Stanfield and made him delete the recording
. The officer then threatened to charge him with felony wiretapping
. The charges were later reduced to disorderly conduct, and Stanfield was forced to testify before a magistrate, who found him guilty. Stanfield's mother said, "Christian's willingness to advocate in a non-violent manner should be championed as a turning point. If Mr. Milburn and the South Fayette school district really want to do the right thing, they would recognized that their zero-tolerance policies and overemphasis on academics and athletics have practically eliminated social and emotional functioning from school culture

An anonymous reader writes "Google has a huge research budget and an apparent willingness to take on huge projects. They've gotten themselves into autonomous cars, fiber optic internet, robotics, and Wi-Fi balloons. But that raises a question: if they're willing to commit to projects as difficult and risk as those, what projects have they explored but rejected? Several of the scientists working at Google's 'innovation lab' have spilled the beans: '[Mag-lev] systems have a stabilizing structure that keeps trains in place as they hover and move forward in only one direction. That couldn't quite translate into an open floor plan of magnets that keep a hoverboard steadily aloft and free to move in any direction. One problem, as Piponi explains, is that magnets tend to keep shifting polarities, so your hoverboard would constantly flip over as you floated around moving from a state of repulsion to attraction with the magnets. Any skateboarder could tell you what that means: Your hoverboard would suck. ... If scaling problems are what brought hoverboards down to earth, material-science issues crashed the space elevator. The team knew the cable would have to be exceptionally strong-- "at least a hundred times stronger than the strongest steel that we have," by Piponi's calculations. He found one material that could do this: carbon nanotubes. But no one has manufactured a perfectly formed carbon nanotube strand longer than a meter. And so elevators "were put in a deep freeze," as Heinrich says, and the team decided to keep tabs on any advances in the carbon nanotube field.'"Read Replies (0)
