A new polymer that can boost capacitors

From hybrid and electric vehicles to underground exploration of fossil-fuels, our search for energy solutions has increasingly placed us in situations demanding electricity storage and delivery under extreme conditions. Though batteries are the reigning storage technology, capacitors are an alternative with several advantages: they’re lightweight, they can be charged and discharged relatively quickly, and they don’t lose their storage capacity over time. In order to function properly, capacitors require dielectric materials, which behave as insulators and are essential for charge storage. Polymeric dielectrics have enhanced performance over other materials, and they can operate under more intense electric fields without failing (termed higher breakdown strength) and greater reliability. They also have the added benefit of practicality, being scalable, lightweight, and easily manipulated. Right now, their major drawback as a material is their inability to work at high temperatures, like those required in many applications. But a composite polymer has finally been developed that seems to break down the traditional limitations of these materials, promising to open up a broader range of uses. Scientists made the new material by crosslinking a traditional polymer embedded with flakes of boron nitride nano sheets. Read 12 remaining paragraphs | Comments

NSA report shows China hacked 600+ US targets over 5 years

NBC has released a 2014 slide from a secret NSA Threat Operations Center (NTOC) briefing—a map that shows the locations of “every single successful computer intrusion” by Chinese state-sponsored hackers over a five-year period. Over 600 US businesses and institutions were breached during that period. The slide was provided to NBC by an unnamed “intelligence source,” who said the briefing “highlighted China’s interest in Google and defense contractors like Lockheed Martin, and in air traffic control systems… [and] catalogued the documents and data Chinese government hackers have exfiltrated,” the network reported. The report suggests that the NSA has been tracking Chinese cyber-attacks for years and that its own network surveillance of China gives the agency the ability to correlate those attacks with specific sources. The briefing shown to NBC listed locations for the sources of each of the “exploitations and attacks,” NBC reported. Read 5 remaining paragraphs | Comments

Ebola vaccine trial in Guinea suggests it’s 100% effective

Today, The Lancet released the results of a large field trial of a vaccine against Ebola, and the results are more than promising. Within the limitations of the study, the vaccine appears to be 100 percent effective. The results were so good that the trial itself has been stopped, and the vaccine is now being used to control the spread of the disease. The vaccine is made by the pharmaceutical giant Merck, which licensed it from the Public Health Agency of Canada. It was developed through what has become a fairly standard approach. A harmless virus ( vesicular stomatitis virus , or VSV) was engineered so that it also carried the gene for Ebola’s major surface protein, simply called glycoprotein. When people receive the vaccination, a harmless infection follows, which triggers an immune response. This response targets not only VSV but the Ebola protein as well. Ideally, once the infection is eliminated, the immune system is able to recognize both VSV and Ebola. The trial, performed in southern Guinea, ran from April through July 20th of this year (the analysis, paper writing, and peer review must have proceeded at a staggering pace). It used what is called a “ring” design: once an infected individual was identified, a ring of potentially exposed individuals around them was identified. These individuals lived with the infected one, had contact with them after symptoms appeared, or came in contact with their clothes, bedding, or bodily fluids. Read 6 remaining paragraphs | Comments

Somalia is no safe refuge for torrent site

In the world of online piracy , it seems like it’s one in, one out at the moment. While The Pirate Bay returned  last week, Kickass Torrents has now been taken down via a domain name seizure. The site, which was already blocked from direct UK access as a result of high court blocking orders, now turns up an error message when users attempt to access its Somali .so domain. A look at its Whois record  shows the site listed as banned. The Somali registry was seen as a safe haven for the site, away from copyright holders and their lawyers, but it appears the takedown was a result of a claim. Several other sites with a .so domain, including the unaffiliated scam site kickasstorrents.so, have also been taken down, which indicates a far-reaching block on any URL with “kickass” in it that is based in the country.

Lucasfilm heads to court to unmask Star Wars: The Force Awakens image leaker

Lucasfilm is demanding that popular photo-sharing site ImageShack cough up the identity of one of its users the studio says uploaded an infringing photograph connected to its upcoming Star Wars movie. ImageShack has already deleted the picture  from user “Darth-Simi” whose account was used to post a picture that was described as a villain from the upcoming Star Wars: The Force Awakens movie. The image included a glimpse of a red crossguard lightsaber like the one showed in a teaser trailer officially released in November. Lucasfilm’s parent company, Disney, is seeking a San Francisco federal court to order California-based ImageShack to turn over Darth-Simi’s personal information. The studio is making the demand  [PDF] to remove the picture “Star Wars Episode VII Costume Design and Photograph” under the Digital Millennium Copyright Act. Read 3 remaining paragraphs | Comments

TracFone must pay $40M for throttling and capping “unlimited” data

TracFone has agreed to pay $40 million “to settle charges that it deceived millions of consumers with hollow promises of ‘unlimited’ data service,” the Federal Trade Commission announced today . Despite advertising unlimited data, the company’s various prepaid wireless brands “drastically slowed or cut off consumers’ mobile data after they used more than certain fixed limits in a 30-day period,” the FTC said. “Beginning today, consumers who had a Straight Talk, Net10, Simple Mobile, or Telcel America unlimited plan before January 2015 can visit  http://ftc.gov/prepaidphones  to file a claim for a refund,” the commission said. “Refunds will be paid to consumers whose data service was slowed or cut off. Consumers who had an unlimited plan but are unsure if their data service was slowed or cut off should still file a claim to find out if they are eligible for a refund.” Read 8 remaining paragraphs | Comments

Apple Remote Desktop admin tool is updated for the first time in forever

There was one other Apple software update that came out yesterday, though it got lost in the shuffle between OS X and iOS system updates and record-breaking financial results . The venerable Apple Remote Desktop (ARD) application has been bumped from version 3.7.2 to version 3.8. Version  3.7.2 was a relatively minor update issued in March of 2014, and version 3.7 goes all the way back to October of 2013. ARD is pretty far off the beaten path, but the short version is that it’s an administrative tool used primarily by IT people to manage large numbers of Macs. It can do standard remote desktop stuff—viewing and taking control of remote Macs’ screens to perform maintenance or help out end users—but it also has a bunch of other handy capabilities. Among other things, administrators can use ARD to push out updates or other software packages to a bunch of Macs at once, run scheduled maintenance, show user and application usage histories, and view hardware and software information for each computer. The biggest addition to version 3.8 is official support for OS X Yosemite, and the update redesigns the app’s icon and UI to mesh better with Yosemite’s new aesthetic. Older versions of ARD supported Yosemite, but performance was quite a bit slower and image quality was visibly poorer than it was for officially supported versions. Improvements to file copying, Full Screen mode, and viewing multiple client desktops at once round out the update. Read 2 remaining paragraphs | Comments

FCC: Blocking Wi-Fi in hotels is prohibited

On Tuesday, the Federal Communications Commission issued an “Enforcement Advisory” stating that blocking W-Fi in hotels is unequivocally “prohibited.” “Persons or businesses causing intentional interference to Wi-Fi hotspots are subject to enforcement action,” the FCC bluntly stated, referencing a dispute between Marriott and its customers who said the hotel chain had blocked their personal hotspots to force them to pay for Marriott’s Wi-Fi services. “The Enforcement Bureau has seen a disturbing trend in which hotels and other commercial establishments block wireless consumers from using their own personal Wi-Fi hot spots on the commercial establishment’s premises,” the FCC wrote. “As a result, the Bureau is protecting consumers by aggressively investigating and acting against such unlawful intentional interference.” Read 2 remaining paragraphs | Comments

iOS 8.1.3 released, reduces the space you need to install updates

Apple has just released iOS 8.1.3, the third patch for iOS 8.1 and the sixth update to iOS 8 since its release. The most significant problem addressed by the new update is that it reduces the amount of free space that you need to install software updates, a problem which has proven especially irritating for owners of 8GB and 16GB iDevices. Currently, users who are using most of their storage either need to delete stuff or connect their phones to iTunes to perform updates, a throwback to pre-iOS 5 releases of the operating system. The update squashes a few other bugs too: it fixes problems keeping some users from entering their passwords for Messages and FaceTime; fixes a problem where Spotlight would stop showing locally installed apps among its search results (this is one we’ve run into); and fixes multitasking gestures for iPad users. Finally, 8.1.3 adds a few configuration options to limit iDevices’ functionality during standardized tests. Read 2 remaining paragraphs | Comments

Apple releases OS X 10.10.2 with a pile of security, privacy, and Wi-Fi fixes

Apple has just released the final build of OS X 10.10.2, the second major update for OS X Yosemite since its release. Version 10.10.1, published just a month after Yosemite’s release, focused mostly on quick fixes for the new OS’ most noticeable problems. Apple has been issuing betas for 10.10.2 since November, though, and a longer testing period usually implies that there are more extensive fixes. First up, the new release is supposed to fix more of the Wi-Fi problems that some users have been experiencing since Yosemite’s launch. 10.10.1 also included Wi-Fi fixes, though it apparently didn’t resolve the problems for all. The new update will also address “an issue that may cause webpages to load slowly” and improve general stability in Safari, all of which should go a long way toward improving Yosemite’s network and Internet performance. Several privacy and security problems that we’ve reported on have been resolved in 10.10.2, as well. Though Apple will still share limited search and location information with Microsoft to enable Spotlight’s Bing-powered Web searching feature, the company has fixed a bug that caused Spotlight to “load remote e-mail content” even when the setting was disabled in Mail.app itself. Our original report describes why this is a problem: Read 3 remaining paragraphs | Comments
