Submission + - Quantum teleportation achieved over 16 km (physorg.com) 1

Laxori666 writes: Scientists in China have succeeded in teleporting information between photons further than ever before. They transported quantum information over a free space distance of 16 km (10 miles), much further than the few hundred meters previously achieved, which brings us closer to transmitting information over long distances without the need for a traditional signal.

Submission + - Facebook Calls All-hands Meeting on Privacy (computerworld.com)

CWmike writes: A Facebook spokesman said that the company will hold an all-staff meeting on Thursday to discuss privacy issues, but would not say whether executives are looking to make significant changes to to the popular site's highly contentious privacy policies following a bevy of changes to the service. In an interview with Computerworld last week, Ethan Beard, director of the site's developer network, defended Facebook's policies and even said users love the changes that Facebook has made. However, it seems calls for people to delete their Facebook accounts, which have gathered momentum, have not fallen on deaf ears at Facebook. Adding to the perception of a crisis on hand, the NY Times profiled on Wednesday a project called Diaspora*, which is creating a more private, decentralized alternative to Facebook.

Submission + - Facebook Changes Clash With EU Privacy Expectation (net-security.org)

An anonymous reader writes: Europeans are well-known for their high privacy expectations and demands. Another proof of that is a letter that the Article 29 Working Party (an independent European Commission advisory body) has sent to Facebook, in which they say it is "unacceptable that the company fundamentally changed the default settings on its social-networking platform to the detriment of a user." This is, of course, not the first negative reaction Facebook has to face for their newly made changes to its Privacy settings. In the US, the Electronic Privacy Information Center and the Federal Trade Commission made their disapproval known. Canada and some European countries have also previously called into question some of Facebook's data policies.

Japanese Researchers Make Plastic Out of Water 117

greenrainbow writes with this excerpt from Inhabit: "The material shown in the picture above is just ice, right? Look again. Elastic water, a new substance invented by researchers at Tokyo University, is a jelly-like substance made up of 95% water along with two grams of clay and a small amount of organic materials. As is, the all-natural substance is perfect for medical procedures, because it's made of water, poses no harm to people, and is perfect for mending tissue. And, if the research team can increase the density of this exciting new substance, it could be used in place of our current oil-based plastics for a host of other things."

Submission + - South Korea Imposes Online Curfew for Online Games (thegamersblog.net)

thsoundman writes: Korea has introduced a pair of policies that will impose a curfew on online games. The curfew has been put in place to help curb the rising number of online game addictions plauging the nations youth. The Korea Herald says “In what’s being touted as the “nighttime shutdown,” the Ministry of Culture, Sports and Tourism hopes the new measures they have implemented will help eradicate video game addiction among teenagers.”

Submission + - Decentralized social networking just became real (onesocialweb.org)

eschnou writes: Onesocialweb is an open source (Apache 2) project aiming at building a free, open, and decentralized social network. Their goal is to make social networking a core internet protocol, just like email, web, or IM are today. The project is built on top of XMPP and leverage open standards such as activitystreams. They have just released the code and opened for federation, so now is a good time to have a look if you are a developer and getting scared of Twitter 'filling the holes' :-)
Perl

Submission + - Perl 5.12.0 is now available (perl.org)

acid06 writes: After two years of development, the new major version of Perl is now available.

Notable new features are: better Unicode support, proper support for time after the Y2038 barrier, new APIs to allow developers to extend Perl with "pluggable" keywords and syntax, warnings for deprecated features and more. From the linked post:

This release cycle marks a change to a time-based release process. Beginning with version 5.11.0, we make a new development release of Perl available on the 20th of each month. Each spring, we will release a new stable version of Perl. One month later, we will make a minor update to deal with any issues discovered after the initial ".0" release. Future releases in the stable series will follow quarterly. In contrast to releases of Perl, maintenance releases will contain fixes for issues discovered after the .0 release, but will not include new features or behavior.

You can get it from the CPAN right now or wait for a platform specific release (such as Strawberry Perl for Windows).

Submission + - MIT Develops Tiny Water Purifying Chip (inhabitat.com)

ByronScott writes: Researchers at MIT have developed a postage stamp-sized water purifier made out of soft silicone that separates out contaminants using magnetic fields. A single device can only process tiny amounts of water, but MIT researchers imagine that they could be lined up in arrays–1,600 units placed on an 8 inch diameter wafer, for example, could generate 15 liters of water an hour. Researchers have successfully tested a single unit, which removed 99% of contaminants from seawater.
Firefox

Submission + - Mozilla Stops Development for Windows Mobile, WP7 (techie-buzz.com)

suraj.sun writes: Mozilla has been building a version of Firefox for Windows Mobile devices for quite some time now with anticipation that Microsoft might increase it’s market share.

However, developing for Windows Phone 7 was not easy considering the restrictions placed on developers. In addition to that, Mozilla also cited that Windows Phone 7 has a closed platform and does not support development of native applications through a NDK. For that reason, Mozilla today announced that they are stopping development of Firefox for all Windows Mobile based devices including the upcoming Windows Phone 7.

"While we think Windows Phone 7 looks interesting and has the potential to do well in the market, Microsoft has unfortunately decided to close off development to native applications. Because of this, we won’t be able to provide Firefox for Windows Phone 7 at this time. Given that Microsoft is staking their future in mobile on Windows Mobile 7 (not 6.5) and because we don’t know if or when Microsoft will release a native development kit, we are putting our Windows Mobile development on hold."

This is definitely bad news for Firefox lovers who have been waiting in anticipation for the Firefox browser on Windows Mobile based devices.

Submission + - Cloaking device makes objects invisible (guardian.co.uk)

GhigoRenzulli writes: Scientists are a step closer to creating a Star Trek-style cloaking device after demonstrating a material that makes objects beneath it appear to vanish. The material was used to hide a bump on a surface by interfering with the way light bounced off it, making it seem as though neither the cloak nor the bump was there. The cloak was designed to make objects invisible to infrared light, but the work paves the way for more advanced materials capable of cloaking objects in visible wavelengths.

Submission + - Laser And Nanoparticle Engine To Reduce Emissions (motorauthority.com)

thecarchik writes: So, how, exactly, does one take low-energy lasers, nanoparticles and fuel and come up with a lean, green machine? The answer is suprisingly simple, if you don't dig too deep. Tiny particles called "functionalized fullerenes" help fuel to burn at lower ignition energies, meaning a lower-power ignition source can be used. That's where the low-power laser comes in. Not much more powerful than a typical laser pointer, the laser sets off the fullerenes, which then ignite the fuel--but because they're nanoparticles and distributed throughout the fuel, they help to make for more complete combustion, improving the overall thermal efficiency of the engine. The sum total of the equation? Less fuel for the same power output.
