Making ultra-thin materials with holes the size of water molecules

While visiting GE’s China Technology Center, we got to take a look at reverse osmosis membranes. Reverse osmosis is the most energy-efficient means of removing dissolved substances from water. It’s what’s used commercially for desalination, the process of producing drinking water from seawater. The term “membrane” is typically used to mean a thin sheet of some material (in fact, the word “sheet” appears in the definition of the term). But for some of the things GE is using it for, the membranes were thin yet robust tubes, each one capable of supporting the weight of a bowling ball. Despite that toughness, features on the tubes are so fine that they can allow water molecules to pass through but reject many things that are roughly the same size, such as the salt ions found in seawater. This all raises an obvious question: how do you actually produce anything like that? We decided to look into the process of making reverse osmosis membranes. Read 12 remaining paragraphs | Comments

Microbots Deliver Medical Payload In Living Creature For the First Time

Zothecula writes: Researchers working at the University of California, San Diego have claimed a world first in proving that artificial, microscopic machines can travel inside a living creature and deliver their medicinal load without any detrimental effects. Using micro-motor powered robots propelled by gas bubbles made from a reaction with the contents of the stomach in which they were deposited, these miniature machines have been successfully deployed in the body of a live mouse.

Office 2016 and Office for Windows touchscreens are due later this year

Word for Windows 10. These touch-optimized apps are separate from the desktop Office suite. 5 more images in gallery The Office tablet and phone apps for iOS and Android both ship with a touch-optimized subset of the features of the full flagship Office suite, and even though Microsoft is readying an Office release for Windows phones and tablets, the desktop version will still reign supreme. Microsoft says that the next version of the flagship suite, dubbed Office 2016, will be “generally available in the second half of 2015.” It will remain optimized for keyboards and mice. The touch-optimized Office apps for Windows 10 are still on their way, though, and Microsoft has shared some screenshots that show what the apps will look like on both phones and tablets. Word, Excel, PowerPoint, OneNote, Outlook Mail, and Outlook Calendar for Windows 10 (the official product names) unsurprisingly share a lot in common with the touchscreen apps for other platforms. Microsoft released Office for iPad in March of 2014 , and that UI has served as the foundation for all the tablet versions of the suite, including the still-in-beta Android version . The phone-sized versions of the apps look more like the new iPhone versions released in November , not like the limited versions that are currently available on Windows phones. The Outlook app for Windows 10 is something we haven’t seen on other platforms yet. Microsoft has released Outlook clients for iOS and Android, but they only support business-class Office 365 accounts and are more or less just wrappers for the standard Outlook Web client. The version for Windows 10 looks more full-featured, more closely resembling the desktop version of Outlook, at least in the three-column tablet view. Read 2 remaining paragraphs | Comments

Hard disk reliability examined once more: HGST rules, Seagate is alarming

A year ago we got some insight into hard disk reliability when cloud backup provider Backblaze published its findings for the tens of thousands of disks that it operated. Backblaze uses regular consumer-grade disks in its storage because of the cheaper cost and good-enough reliability, but it also discovered that some kinds of disks fared extremely poorly when used 24/7. A year later on and the company has collected even more data , and drawn out even more differences between the different disks it uses. For a second year, the standout reliability leader was HGST. Now a wholly-owned subsidiary of Western Digital, HGST inherited the technology and designs from Hitachi (which itself bought IBM’s hard disk division). Across a range of models from 2 to 4 terabytes, the HGST models showed low failure rates; at worse, 2.3 percent failing a year. This includes some of the oldest disks among Backblaze’s collection; 2TB Desktop 7K2000 models are on average 3.9 years old, but still have a failure rate of just 1.1 percent.

Liveblog: Windows 10 “The Next Chapter” event on January 21st

REDMOND—Microsoft is unveiling the next major beta of Windows 10, the Consumer Preview, with an event at the company’s home in Redmond, Washington. We’ll be on the scene to report on the news and get a first look at the new release. We’re expecting to see the new Continuum feature that adapts the Windows interface on 2-in-1 devices and a new browser that sheds the legacy (and name) of Internet Explorer. Representatives of the Xbox team will also be at the event, with Microsoft having news about Windows gaming—though precisely what that will be is currently a mystery. Read on Ars Technica | Comments

How installing League of Legends and Path of Exile left some with a RAT

Official releases for the League of Legends and Path of Exile online games were found laced with a nasty trojan after attackers compromised an Internet platform provider that distributed them to users in Asia. The compromise of consumer Internet platform Garena allowed the attackers to attach malicious software components to the official installation files for the two games, according to a blog post published Monday by antivirus provider Trend Micro. In addition to the legitimate game launcher, the compromised executable file also included a dropper that installed a remote access tool known as PlugX and a cleaner file that overwrote the infected file after it ran. According to Trend Micro, the attackers took care to conceal their malware campaign, an effort that may have made it hard for victims to know they were infected. The cleaner file most likely was included to remove evidence that would tip users off to a compromise or the origin of the attack. The cryptographic hash that was included with the tampered game files was valid, so even people who took care to verify the authenticity of the game installer would have no reason to think it was malicious, Trend Micro researchers said. The researchers linked to this December 31 post from Garena . Translated into English, one passage stated: “computers and patch servers were infected with trojans. As a result, all the installation files distributed for the games League of Legends and Path of Exile are infected.” Read 2 remaining paragraphs | Comments

British spy agency captured 70,000 e-mails of journalists in 10 minutes

The Government Communications Headquarters (GCHQ), the British sister agency of the National Security Agency, captured 70,000 e-mails of journalists in 10 minutes during a November 2008 test. According to The Guardian , which on Monday cited some of its Snowden documents as its source (but did not publish them), the e-mails were scooped up as part of the intelligence agency’s direct fiber taps . Journalists from the BBC, Reuters, The Guardian, The New York Times, Le Monde, The Sun , NBC, and The Washington Post were apparently targeted. Read 2 remaining paragraphs | Comments

This Ingestible Nanobot Is Powered By Stomach Acid 

There’s tiny revolution afoot in medicine, where micro- and nano-sized robots will someday cruise around inside our bodies, zeroing in on cancerous cells or repairing damaged but otherwise healthy ones . But before those ideas all become reality, those bots need a power source inside our bodies. That power source could be stomach acid. Read more…

Pirates defeating watermarks, releasing torrents of Oscar movie screeners

When an incomplete and early version of the X-Men Origins: Wolverine leaked to torrent sites in 2009, Twentieth Century Fox announced that the uploader “will be prosecuted to the fullest extent of the law.” “We forensically mark our content so we can identify sources that make it available or download it,” the studio said in a statement. Nabbed by a watermark, a New York man subsequently pleaded guilty to making the movie available on Megaupload. Gilberto Sanchez was sentenced to a year in prison in 2011. A triumphant US Attorney Andre Birotte Jr . said  that  “sentence handed down in this case sends a strong message of deterrence to would-be Internet pirates.” Read 6 remaining paragraphs | Comments
