Replicating Hardest Known Biomaterial Could Improve Solar Cells and Batteries

cylonlover writes “Inspired by the tough teeth of a marine snail and the remarkable process by which they form, assistant professor David Kisailus at the University of California, Riverside is working toward building cheaper, more efficient nanomaterials. By achieving greater control over the low-temperature growth of nanocrystals (abstract), his research could improve the performance of solar cells and lithium-ion batteries, lead to higher-performance materials for car and airplane frames, and help develop abrasion-resistant materials that could be used for anything from specialized clothing to dental drills.” Read more of this story at Slashdot.

All backscatter “pornoscanners” to be removed from US airports

Bloomberg is reporting that the TSA will be removing all of the remaining backscatter X-ray machines from US airports. The removal isn’t because of health concerns—instead, the machines’ manufacturer, Rapiscan Systems , failed to meet a US Congress-imposed deadline for altering the machines’ software to produce “generic passenger images,” according to the report. TSA assistant administer for acquisitions Karen Shelton Waters, speaking on behalf of the agency, noted that Rapiscan Systems would absorb the cost for the scanners’ removal, and that the removal is unrelated to Rapiscan’s alleged falsification of the machines’ abilities to protect passengers’ privacy. Nor does the removal appear to be related to ongoing questions about the safety of the backscatter X-ray technology. The CEO of OSI systems, Rapiscan’s parent company, says that rather than pitching the expensive machines into the garbage bin, the TSA will be relocating them to other government agencies. In total, there are 174 Rapiscan backscatter X-ray machines that will be pulled from airports and relocated, on top of the 76 that were  removed last year. Read 1 remaining paragraphs | Comments

Microsoft releases emergency update to patch Internet Explorer bug

Microsoft has released an emergency update to patch a security vulnerability in Internet Explorer that is being exploited in attacks aimed at government contractors and other targeted organizations. The patch fixes a “use after free” bug in versions 6, 7, and 8 of the Microsoft browser and will be automatically installed on affected machines that have automatic updating enabled, Dustin Childs, the Group Manager of the company’s Trustworthy Computing program wrote in a blog post published Monday . The unscheduled release comes just six days after Microsoft’s most recent monthly Patch Tuesday batch of security updates, but it was pushed out to counter an experienced gang of hackers who have infected websites frequented by government contractors to exploit the vulnerability. Monday’s update came hours after Oracle released an unscheduled patch to fix a critical vulnerability in its Java software framework. As Ars reported last week , the zero-day Java exploits were added to a variety of exploit kits that criminals use to turn compromised websites into platforms for silently installing keyloggers and other malware on the machines of unsuspecting visitors.

New Threadlike Carbon Nanotube Fiber Unveiled

Zothecula writes “At about 100 times the strength of steel and a sixth the weight, with impressive electrical conductive properties, carbon nanotubes (CNTs) have promised much since their discovery in 1991. The problem has been translating their impressive nanoscale properties into real-world applications on the macro scale. Researchers have now unveiled a new CNT fiber that conducts heat and electricity like a metal wire, is very strong like carbon fiber, and is flexible like a textile thread.” Read more of this story at Slashdot.

Fastest Wi-Fi ever is almost ready for real-world use

Wilocity’s wireless chips allow 4.6Gbps transmission over the 60GHz band. Wilocity In a quiet suite removed from the insanity of the Consumer Electronics Show expo floor, a company aiming to build the fastest Wi-Fi chips in the world demonstrated its vision of wireless technology’s future. On one desk, a laptop powered a two-monitor setup without any wires. At another, a tablet playing an accelerometer-based racing game mirrors its screen in high definition to another monitor. Across the room, a computer quickly transfers a 3GB file from a wireless router with built-in storage. The suite was set up in the Las Vegas Hotel by Wilocity , a chip company specializing in wireless products using 60GHz transmissions, which are far faster than traditional Wi-Fi. Avoiding the show floor is a good idea if you’re worried about Internet connectivity, because thousands of vendors are clogging the pipes. But that’s not why Wilocity was here—they’d be able to perform the demo even in the busiest parts of CES without interference because they’re not relying on the congested bands used by regular Wi-Fi.

Walmart to sell iPhones with a $45 per month unlimited prepaid plan

Starting this Friday, Walmart will be selling the iPhone for use with wireless provider Straight Talk, which is offering a $45-per-month contract with unlimited voice, data, and texting. This sale will make it one of the cheapest ways —as measured over a two-year period—to get a prepaid iPhone. Walmart says it will offer $25-per-month financing for the phone itself if customers use a Walmart credit card. Straight Talk, which uses AT&T’s towers as a mobile virtual network operator (MVNO), is becoming an increasingly popular option for prepaid customers who want to use an iPhone without paying high prices. (Full disclosure: I am a Straight Talk customer, and have been since April 2012.) “We believe customers shouldn’t have to choose between saving money and having the latest technology,” said Seong Ohm, senior vice president of Entertainment for Walmart US, said in a statement on Tuesday. “Now customers can have the coveted iPhone with unlimited talk, text, and data without a contract for $70 a month thanks to our exclusive Straight Talk plan and industry first financing offer.” Read 1 remaining paragraphs | Comments

Satellite Internet: 15Mbps, no matter where you live in the US

billrdio America is a land of haves and have-nots when it comes to broadband Internet. While many of us enjoy downloads speeds of 50 or even 100 Mbps, 119 million Americans lack broadband access (defined as 4Mbps down and 1Mbps up). Out of those 119 million, 19 million live in areas where there is no option to buy a wired broadband connection, according to government data. Wouldn’t it be great if we could provide broadband speed to nearly every American, without costly construction projects to bring cables to the home? Apparently, we already can . At least that’s what providers of satellite broadband Internet services said today in a panel at the Consumer Electronics Show in Las Vegas. Latest-generation satellites operated by HughesNet and ViaSat offer 10 to 15 Mbps down and 1 to 3 Mbps up to nearly any home in the US, representatives of those companies said. They believe the industry simply suffers from an awareness problem. Previous-generation satellite products offered only a fraction of that speed, and even people who realize satellite is available to them may not know that the latest products are as fast as they are.

Lenovo talks up new 27-inch “table PC” at CES

Lenovo’s IdeaCentre Horizon 27 Lenovo Lenovo is just one of the many PC makers bringing new designs to CES this week. Many of these will simply be refreshed or refined versions of the first round of Windows 8 computers—either convertible laptops or more traditional desktops and laptops with integrated touchscreens—but a few particularly interesting designs may yet rise above that fray. One of these PCs is Lenovo’s IdeaCentre Horizon 27, a 27-inch all-in-one desktop PC with an integrated battery and 1080p ten-point touchscreen. Lenovo is marketing the device as a “table PC.” Sure, a kickstand can be unfolded to allow the computer to sit on a desk as would any all-in-one. But this PC can also be laid flat on a table for use by multiple people, or mounted on the pictured roller table for use while standing. (We’ve previously stated  a touchscreen all-in-one makes the most sense ergonomically while positioned at about waist height on a standing person.) Enlarge / A roller table will change the Horizon into a standing workstation, when needed. Lenovo In concept the Horizon is quite similar to Sony’s Tap 20 , a smaller all-in-one that also included an integrated battery and foldable kickstand allowing it to be laid flat on a table. The Horizon’s larger size will mean more people can gather around it at once (and the roller table may make it more useful for people who prefer to stand at their desks), but the two machines are definitely cut from the same cloth. Like the Tap 20, multiplayer touch-enabled games figure heavily into Lenovo’s promotional material for the device. Read 1 remaining paragraphs | Comments

Leader of BitTorrent piracy ring sentenced to five years in prison

The leader of the notorious IMAGiNE BitTorrent piracy ring, Jeramiah Perkins, was sentenced on Thursday to five years in prison, the largest sentence for the group’s five top administrators. In August 2012, Perkins pleaded guilty to one count of conspiracy to commit criminal copyright infringement. After being given the maximum sentence today, Perkins was also ordered to serve three years under “supervised release” and must pay $15,000 in restitution. As we reported in April, the group used infrared and FM receivers and camcorders to capture new releases in movie theaters. In a statement , the Department of Justice cited testimony from the Motion Picture Association of America, calling the group “the most prolific motion picture piracy release group operating on the Internet from September 2009 through September 2011.” Read 2 remaining paragraphs | Comments
