$20 reusable chip detects type-1 diabetes quickly and cheaply

Source: http://www.engadget.com/2014/07/14/cheap-diabetes-test/

Researchers from Stanford University have developed a microchip that could make it much less costly to diagnose type-1 diabetes. The debilitating disease often strikes children, and the quicker it's detected, the easier it is to treat. The current test, however, is a time-consuming, costly burden for both hospitals and patients, requiring radioactive materials and several days of time. The new chip uses gold nanoparticles that cause fluorescent materials to glow when telltale antibodies are detected. Unlike the old tests, only a pinprick of blood is required, and the $20 chip can be reused up to 15 times. Such diagnostics could compliment other diabetes research, like Google's glucose detecting smart contacts, along with potential treatments or even cures. Researchers said the test will be particularly useful in countries where the standard test is too expensive, and are now working to launch it globally.

MIT's new material opens the door to squishable, shape-shifting robots

MIT's shape-shifting robot material

Robots tend to be either very rigid or very soft, but neither extreme is ideal; ideally, machines could both squish themselves into tight spaces and remain sturdy for strength-dependent tasks. They just might, thanks to a team-up between MIT and Google's Boston Dynamics. The two have developed a composite material that can switch between hard and soft states on the fly. The design mates a compressible foam inside with an external wax coating. If a robot needed to deform, all it would have to do is soften the right joints with a bit of heating. It could even heal damage by heating and cooling an affected area.

It's still early days, but there are already plenty of potential real-world applications for the material. DARPA (the impetus for the project) wants robots that can literally slip through the cracks to reach otherwise inaccessible areas; they could rescue survivors trapped under rubble, for example. MIT, meanwhile, pictures surgical bots that could repair hard-to-reach body parts. We're still a long, long way from the liquid metal of Terminator 2's T-1000, but these findings suggest that the concept of a shape-shifting automaton isn't completely far-fetched.

Microsoft says super-cheap Windows devices are on the way

Source: http://www.engadget.com/2014/07/14/microsoft-says-super-cheap-windows-devices-are-on-the-way/

It used to be that if you only wanted to pay $199 for a brand-new laptop, you'd have to try your luck on Black Friday or pick up a Chromebook. Not so anymore. Microsoft COO Kevin Turner outed a $199 HP Windows laptop called the Stream at the company's Worldwide Partner Conference this morning, and it should see the light of day in time for the holiday season. Fine, it doesn't sound like the biggest deal ever. There are already a few solid Windows laptops floating around there for less than $100 more, after all, and at this point no one's sure what $199 will actually get you. That's a fair point, but c'mon: on some level this move is all about symbolism. Microsoft is telling the industry -- and the consumers that fuel that immaculate machine -- that it's not giving up low-end computing to Google without a fight.

Nadella and his crew are banking on the fact that Windows provides greater functionality and extensibility than ChromeOS right out of the box. When computer shoppers can own the full Windows experience (for better or worse) for the same price as committing to a Chrome-y connected lifestyle, they'll have to mull that choice over. That's exactly what Microsoft wants. Turner also confirmed that the next few months would bring at least a few full-blown Windows tablets priced to move at $99. That announcement wasn't as much of a surprise since the folks in Redmond revealed that the OS would be free to manufacturers when its installed on device's with screens under 9 inches. It was only a matter of time, but hey -- that doesn't make the gesture any less meaningful.

Secret widens its anonymous network to include your Facebook friends too

Source: http://www.engadget.com/2014/07/14/secret-adds-facebook-login-collections/

When Secret first launched earlier this year, the only subscribers who could see your anonymous missives on the app were folks who were somehow connected to your phone's address book -- they were either your friends, friends of friends, or friends of friends of friends (you get the idea). Now, however, Secret has loosened that restriction just a touch with the introduction of Facebook login support. Now if you sign up with Facebook on the app, you'll be able to spill your secrets to all your Facebook friends who are also on Secret. Of course, the company promises that no personal information is ever shared and you'll still be completely anonymous. On the one hand, this lets those of us who have more friends on Facebook than on on our phone's address book see more Friend posts on Secret. On the other, it does give us a tiny bit of the creeps. Thankfully, the feature is completely optional, so you don't have to participate if you don't want to.

Secret also announced another feature today called Collections, which are simply daily digests of posts from a certain category. You can go to Secret's brand new web interface and subscribe to any of the available Collections -- current categories include Popular, Dating, Reflections, Funny, Work and Loss. If you do subscribe, you'll get secrets from that collection in your Explore stream. This definitely narrow the kinds of posts you see on Explore quite a bit, and it seems like it lets you hone in more on what you prefer to see on there. According to the folks at Secret, they're still experimenting on how to give users more control over what they see on Explore, which can be a rather daunting task given the growing popularity of the network. If that sounds like something you'd be interested in, head on over to the source link to find out more. Don't worry, we won't tell anyone.

drag2share: This Robot Has Written More Wikipedia Articles Than Anyone Alive

source: http://feedproxy.google.com/~r/businessinsider/~3/n0Zu2Mgo8vc/robot-most-prolific-wikipedia-author-2014-7

Wikipedia

You might think writing 10,000 articles per day would be impossible. But not for a Swede named Sverker Johansson. He created a computer program that has written a total of 2.7 million articles, making Johansson the most prolific author, by far, on the "internet's encyclopedia." His contributions account for 8.5 percent of the articles on Wikipedia, the Wall Street Journal reports.

But how can a bot write so many articles, and do it coherently? As Johansson--a science teacher with degrees in linguistics, civil engineering, economics and particle physics--explained to the WSJ, the bot scrapes information from various trusted sources, and then cobbles that material together, typically into a very short entry, or "stub." Many of the articles cover the taxonomy of little-known animals such as butterflies and beetles, and also small towns in the Philippines (his wife is Filipino).

Johansson's creation, known as Lsjbot, is certainly not the only bot to write articles meant for human eyes. For example, the Associated Press just announced that it will use robots to write thousands of pieces, and other news outlets use programs to write articles, especially finance and sports stories. And on Wikipedia, half of all of the edits are made by bots.

Several long-time members of Wikipedia are not happy that so many articles are being written by non-humans. But Johansson defends his bot, pointing out that the articles it writes are accurate (although there have been some glitches that he claims have been corrected), and can! very us eful. For example, Lsjbot wrote a stub about the town of Basey, in the Philippines. When Typhoon Yolanda hit the town, causing deaths, people were able to visit this stub and find out more about the town and its location.
