Cassini points to a hidden ocean on Saturn’s icy moon

I carry an ocean in my womb. NASA/JPL/SSI/J Major Finding liquid water on a body within the Solar System is exciting. The only thing that is probably more exciting is finding an ocean full of it. Today such news comes via Cassini, which has made measurements that show that Saturn’s moon Enceladus has a hidden ocean beneath its icy surface. While orbiting Saturn in 2005, Cassini found jets of salty water spewing from the south polar region of Enceladus. According to Luciano Iess of Sapienza University of Rome, lead author of the new study published in Science , “The discovery of the jets was unexpected.” Geysers require liquid water, and we wouldn’t expect Enceladus to have any. It is too far from the Sun to absorb much energy and too small (just 500km in diameter) to have trapped enough internal energy to keep its core molten. The answer to how the water got there might lie in the details of the moon’s internal structure. Read 13 remaining paragraphs | Comments

Google Wireless: Google Fiber cities could get mobile service, but to what end?

Through Google Fiber, Google is already an Internet service provider, piping Gigabit Internet to homes and businesses in a handful of cities across the US. According to a report from The Information (paywall)  Google has been considering supplementing Google Fiber’s home Internet access with a wireless cellular service. Google’s plan wasn’t to build towers, but to become a Mobile Virtual Network Operator (MVNO)—basically a middle man who buys service from one of the “big four” carriers at wholesale prices and resells that to consumers under its own brand. According to the report, Google spoke to Sprint and then Verizon about reselling their networks to customers, with the Verizon talks happening earlier this year. The service would be available to users in Google Fiber cities, and it would be supplemented with free Wi-Fi hotspots. What would Google hope to  accomplish  with a move like this?  Google built Google Fiber from the ground up by putting fiber on poles, running connections to each house, and providing self-built hardware. Complete control over every part of the network allows Google to differentiate Google Fiber in several ways, like service location, speed, and pricing. Google’s plan for its wireless service appears to be much less ambitious, though. A s an MVNO, Google would be using someone else’s network, so the only thing Google would really have control over is the resale price. The whole point of Google Fiber is to “shame” other ISPs into increasing their speeds and lowering their prices. Google doesn’t plan on covering the entire country in fiber, but one look at Google’s 1,000Mbps service for $70 and the traditional ISP plan of 5 to 15Mbps for about the same price looks like a huge ripoff. This ” halo effect ” puts pressure on ISPs to speed up their service, and that makes Google products like search and YouTube run faster. The strategy seems to be working, with companies like AT&T rolling out fiber in response . As an MVNO, Google can’t do anything like the Google Fiber strategy, since it isn’t running the network. It won’t have control over speed or reception, meaning the best it can do to stand out is resell the service very cheaply. Unfairly competing with wireless carriers by pricing to only break even doesn’t seem like it would put much pressure on other carriers, because they would realize Google isn’t trying to turn a profit.

Hasenkopf’s ‘Frescata’ Material-Processing Technology Yields Beautiful and Unique Surfaces

One of the cooler materials we saw at Holz-Handwerk wasn’t really a material at all, but a process. German industrial manufacturer Hasenkopf’s booth drew a steady stream of visitors all reaching out to touch the weird-looking totems, like the one above, that they had on display; I eagerly checked the product tag to find it was nothing more than Corian. So what gives? Hasenkopf was showing off their bag of new material-processing tricks called Frescata , whereby they hit Corian, Parapan, and even wood with four different bits in a five-axis CNC mill to create the intricate patterns you see here.

One Ring To Rule It All… By Bluetooth

Get ready for the Internet of Rings . Today’s the last day to jump on the earlybird bandwagon for Ring, which has completely cleaned house over on Kickstarter . In case you missed the digital memo, Ring is a wearable device that allows you to “control anything” and “shortcut everything” (or so its creators at Logbar claim). Enticingly vague promises, backed up by tight tech design and a pretty intense bank of R&D. The innovation at the heart of the device is fine gesture recognition—put it on your finger, tap the side to activate and your finger’s moves are registered and transmitted to the device of choice. From there, you get a lot of functionality: control appliances, send texts, make payments through Ring’s gateway, and get vibration or LED notifications. If you can sync it, you can rule it with Ring. To futz with your Bluetoothed lamp, draw a lamp in the air. To draft a letter, draw a letter and then start spelling. The instant payment feature is a little surprising, but an interesting take on the common interaction. In addition to the “built in” symbols and controls, you can add your own personalized finger-commands. They’re opening the API for app developers who want to get in on the Ring game, and have a store to make Ring-related apps easy to find. The charging dock is pretty boss, and they estimate it can perform about 1, 000 gestures per charge. They’re also offering it in a range of sizes, so you apes and dainty types aren’t out of luck. Onward, to the future! (more…)

The Crazy Things Delta Does to Cancel Fewer Flights Than Any Airline

Last year, Delta Air Lines canceled fewer flights than any other airline, scratching just 0.3 percent of its flights. That’s more than five times better than the industry average. It’s an obsession for Delta, an airline that once ranked near rock-bottom for cancellations, and as The Wall Street Journal explains , the company strives for zero-cancellation days in some very unorthodox ways.

The Untold History of Where Barcodes Come From

When George Laurer goes to the grocery store, he doesn’t tell the check-out people that he invented the barcode, but his wife used to point it out. “My husband here’s the one who invented that barcode, ” she’d occasionally say. And the check-out people would look at him like, “you mean there was a time when we didn’t have barcodes?” Read more…

60 Minutes Dubbed Engines Noise Over Tesla Model S

cartechboy (2660665) writes “Did you watch the Tesla 60 Minutes segment the other night? If you did, you might have ended up on the floor rolling around laughing like I did. Since when does the Tesla Model S electric car make audible engine noises? Or downshift? Turns out, 60 Minutes dubbed engine noises and a downshift over the Model S running footage. The show claims it was an editing error. Call it what you want, it was absolutely hilarious. A little note to TV producers assigned to cover Tesla Motors in the future: Electric cars don’t upshift or downshift.” At least they didn’t fraudulently blow it up!

Russian GLONASS Down For 12 Hours

An anonymous reader writes “In an unprecedented total disruption of a fully operational GNSS constellation, all satellites in the Russian GLONASS broadcast corrupt information for 11 hours, from just past midnight until noon Russian time (UTC+4), on April 2 (or 5 p.m. on April 1 to 4 a.m. April 2, U.S. Eastern time). This rendered the system completely unusable to all worldwide GLONASS receivers.” Read more of this story at Slashdot.

Watch a piece of aluminum levitate and melt at the same time

This is an induction heater, an electromagnetic thingamajig that can make metal to levitate and—with enough power—melt it. In this case, the metal is a 2.6-gram piece of aluminum that reaches a temperature of 2192 F (1200 C) before the machine is turned off. Read more…
