Artificial Muscles Pack a Mean Punch

sciencehabit writes “Here’s a twist: Scientists have designed a flexible, yarn-like artificial muscle that can also pack a punch. It can contract in 25 milliseconds—a fraction of the time it takes to blink an eye—and can generate power 85 times as great as a similarly sized human muscle. The new muscles are made of carbon nanotubes filled with paraffin wax that can twist or stretch in response to heat or electricity. When the temperature rises, the wax melts and forces the nanotubes to contract. Such artificial muscles, the researchers say, could power smart materials, sensors, robots, and even devices inside the human body.” Read more of this story at Slashdot.

Google Engineers Open Source Book Scanner Design

c0lo writes “Engineers from Google’s Books team have released the design plans for a comparatively reasonably priced (about $1500) book scanner on Google Code. Built using a scanner, a vacuum cleaner and various other components, the Linear Book Scanner was developed by engineers during the ’20 percent time’ that Google allocates for personal projects. The license is highly permissive, thus it’s possible the design and building costs can be improved. Any takers?” Adds reader leighklotz: “The Google Tech Talk Video starts with Jeff Breidenbach of the Google Books team, and moves on to Dany Qumsiyeh showing how simple his design is to build. Could it be that the Google Books team has had enough of destroying the library in order to save it? Or maybe the just want to up-stage the Internet Archive’s Scanning Robot. Disclaimer: I worked with Jeff when we were at Xerox (where he did this awesome hack), but this is more awesome because it saves books.” Read more of this story at Slashdot.

Australia's Biggest Telco Sold Routers With Hardcoded Passwords

mask.of.sanity writes “Hardcoded usernames and passwords have been discovered in a recent line of Telstra broadband routers that allow attackers access to customer networks. The flaws meant customer unique passwords could be bypassed to access the device administrative console and LAN.” Read more of this story at Slashdot.

MOOC Mania

theodp writes “Online education has had a fifty-year road to ‘overnight’ success. MIT Technology Review calls the emergence of free online education, particularly massive open online courses (MOOCs), The Most Important Education Technology in 200 Years. ‘If you were asked to name the most important innovation in transportation over the last 200 years,’ writes Antonio Regalado, ‘you might say the combustion engine, air travel, Henry Ford’s Model-T production line, or even the bicycle. The list goes on. Now answer this one: what’s been the single biggest innovation in education? Don’t worry if you come up blank. You’re supposed to.’ Writing about MOOC Mania in the Communications of the ACM, Moshe Y. Vardi worries that ‘the enormous buzz about MOOCs is not due to the technology’s intrinsic educational value, but due to the seductive possibilities of lower costs.’ And in MOOCs Will Eat Academia, Vivek Haldar writes, ‘MOOCs will almost certainly hollow out the teaching component of universities as it stands today…But all is not lost, because the other thing universities do is research, and that is arguably as important, if not more, than teaching.’ So, are MOOCs the best thing since sliced bread, or merely the second coming of 1920s Postal Course Mania?” Read more of this story at Slashdot.

Super-Earth Discovered In Stars' Habitable Zone

astroengine writes “The family of planets circling a relatively close dwarf star has grown to six, including a potential rocky world at least seven times more massive than Earth that is properly located for liquid water to exist on its surface, a condition believed to be necessary for life. Scientists added three new planets to three discovered in 2008 orbiting an orange star called HD 40307, which is roughly three-quarters as massive as the sun and located about 42 light-years away in the constellation Pictor. Of particular interest is the outermost planet, which is believed to fly around its parent star over 320 days, a distance that places it within HD 40307’s so-called “habitable zone.”” Read more of this story at Slashdot.

Microsoft Retiring Messenger, Replacing It With Skype

Entropy98 writes “Windows Live Messenger will be shut down by March 2013, after nearly 13 years of service, so Microsoft can focus its efforts on Skype, its recent $8.5bn acquisition. No word on whether users will be able to transfer their WLM accounts to Skype. ‘According to internet analysis firm Comscore, WLM still had more than double the number of Skype’s instant messenger facility at the start of this year and was second only in popularity to Yahoo Messenger. But the report suggested WLM’s US audience had fallen to 8.3 million unique users, representing a 48% drop year-on-year. By contrast, the number of people using Skype to instant message each other grew over the period.'” Read more of this story at Slashdot.

Microsoft-Built Smartphone Could Irritate Hardware Partners, Harm Nokia

Nerval’s Lobster writes “Rumors have circulated for weeks that Microsoft intends to release a smartphone of its own design and manufacture, embracing the strategy that drove Apple’s iPhone to such enormous success over the past few years. While releasing a branded smartphone offers several potential benefits—look at the revenue and brand recognition Apple’s earned as a result of the iPhone—such a strategy also carries significant risks for Microsoft. First, it could alienate smartphone partners such as Nokia, which would find itself competing against a high-end device backed by Microsoft’s sizable marketing dollars. (Given the Finnish phone-maker’s already perilous situation, that could prove ruinous.) But a branded smartphone could also convince hardware manufacturers that Microsoft really is ‘all in’ on building its own devices, which could lead to all sorts of drama.” Read more of this story at Slashdot.

Amazon Charges Sales Tax On "Shipping and Handling"

You may have noticed that retailers like Amazon are charging tax, in compliance with state laws, on not just the price of goods, but on the “shipping and handling” fees they charge. An anonymous reader writes “By coincidence I noticed this myself the other night, and ended up ordering something from a supplier in Arizona, rather than Amazon, to avoid the sales tax. Now here is an article about it in the Los Angeles Times.” Read more of this story at Slashdot.

Breakthrough Promises Smartphones that Use Half the Power

Dupple writes in with news about a discovery that should extend the life of your battery in the near future. “Powering cellular base stations around the world will cost $36 billion this year—chewing through nearly 1 percent of all global electricity production. Much of this is wasted by a grossly inefficient piece of hardware: the power amplifier, a gadget that turns electricity into radio signals. The versions of amplifiers within smartphones suffer similar problems. If you’ve noticed your phone getting warm and rapidly draining the battery when streaming video or sending large files, blame the power amplifiers. As with the versions in base stations, these chips waste more than 65 percent of their energy—and that’s why you sometimes need to charge your phone twice a day. It’s currently a lab-bench technology, but if it proves itself in commercialization, which is expected to start in 2013—first targeting LTE base stations—the technology could slash base station energy use by half. Likewise, a chip-scale version of the technology, still in development, could double the battery life of smartphones.” Read more of this story at Slashdot.

New York Data Centers Battle Floods, Utility Outages

miller60 writes “At least three data center buildings in lower Manhattan are struggling with power problems amid widespread flooding and utility outages caused by Hurricane Sandy. Flooded basements at two sites took out diesel fuel pumps, leaving them unable to refuel generators on higher levels. One of these was Datagram, which knocked out Buzzfeed and the Gawker network of sites. At 111 8th Avenue, some tenants lost power when Equinix briefly experienced generator problems.” The NY Times has a running list of Sandy-related problems, including 5,700 more flight cancellations, 6 million people without power, rising water levels at a nuclear plant, official disaster declarations from President Obama, and a death toll of 38. On the upside, and despite the high water levels, the Nuclear Energy Institute was quick to point out that all 34 nuclear facilities in Sandy’s path made it through without problems.
