We brought down Challenger space shuttle in 1986, claims Turkish sect leader

The Challenger space shuttle, which exploded a few minutes after launching in 1986, was brought down by members of the Naqshbandi spiritual order in Turkey, one of the group’s leaders has claimed in a video that has gone viral on social media.Ahmet Yasin Bursevi said the cause of the explosion of the space shuttle was the slackening of its cap screws by members of the Naqshbandi order.“We were in the middle of the Hatme [a kind of dhikr ritual] when the challenger departed. There was no television in the room. Uncle Ahmet [one of the members of the group] started to speak loudly during the ritual, saying ‘why hasn’t it exploded yet?’ Uncle Mehmet Emin [another member] responded, saying ‘don’t worry. We have loosened its cap screws. It will go down soon.’ The shuttle went down at the same time. We learned it from the TV the next day,” Bursevi says in the video.

LSEV is a $7,500 3-D printed electric car from XEV

Mass production of 3-D printed cars is coming soon. The first will be from start-up XEV and Polymaker, a developer of 3-D printing materials.

The $7,500 car, called LSEV, only took three days to make according to the creator. All of the components in LSEV were printed except for the chassis, seats and glass.

The two-seater looks a lot like a Smart car, but it isn’t quite as fast. Its top speed is about 43 miles per hour. It can travel about 93 miles on a single charge.

The car will be available in Asia and Europe in 2019.

Illusory movement perception improves motor control for prosthetic hands

Good vibrations for movement perceptionThe ability to sense the spatial position and movements of one’s own body (kinesthetic sense) is critical for limb use. Because prostheses do not provide physical feedback during movement, amputees may not feel that they are in control of their bodily movements (sense of agency) when manipulating a prosthesis. Marasco et al. developed an automated neural-machine interface that vibrates the muscles used for control of prosthetic hands. This system instilled kinesthetic sense in amputees, allowing them to control prosthetic hand movements in the absence of visual feedback and increasing their sense of agency. This approach might be an effective strategy for improving motor performance and quality of life in amputees.AbstractTo effortlessly complete an intentional movement, the brain needs feedback from the body regarding the movement’s progress. This largely nonconscious kinesthetic sense helps the brain to learn relationships between motor commands and outcomes to correct movement errors. Prosthetic systems for restoring function have predominantly focused on controlling motorized joint movement. Without the kinesthetic sense, however, these devices do not become intuitively controllable. We report a method for endowing human amputees with a kinesthetic perception of dexterous robotic hands. Vibrating the muscles used for prosthetic control via a neural-machine interface produced the illusory perception of complex grip movements. Within minutes, three amputees integrated this kinesthetic feedback and improved movement control. Combining intent, kinesthesia, and vision instilled participants with a sense of agency over the robotic movements. This feedback approach for closed-loop control opens a pathway to seamless integration of minds and machines

Google Builds A Synthesizer With Neural Nets And Raspberry Pis. 

AI is the new hotness! It’s 1965 or 1985 all over again! We’re in the AI Rennisance Mk. 2, and Google, in an attempt to showcase how AI can allow creators to be more… creative has released a synthesizer built around neural networks.The NSynth Super is an experimental physical interface from Magenta, a research group within the Big G that explores how machine learning tools can create art and music in new ways. The NSynth Super does this by mashing together a Kaoss Pad, samples that sound like General MIDI patches, and a neural network.Here’s how the NSynth works: The NSynth hardware accepts MIDI signals from a keyboard, DAW, or whatever. These MIDI commands are fed into an openFrameworks app that uses pre-compiled (with Machine Learning™!) samples from various instruments. This openFrameworks app combines and mixes these samples in relation to whatever the user inputs via the NSynth controller. If you’ve ever wanted to hear what the combination of a snare drum and a bassoon sounds like, this does it. Basically, you’re looking at a Kaoss pad controlling rompler that takes four samples and combines them, with the power of Neural Networks. The project comes with a set of pre-compiled and neural networked samples, but you can use this interface to mix your own samples, provided you have a beefy computer with an expensive GPU.

Glam Glow Will Sell My Little Pony Face Masks at Sephora

Insta-famous beauty brand Glam Glow announced the release of its new limited-edition glitter masks last night on its favorite platform, by way of vloggers Chrisspy and MakeupShayla. The masks are sure to be just as photogenic and trending as every other Glam Glow mask — remember the green and gold Power Rangers ones? These new ones were all inspired by My Little Pony and are pure magic in more ways than one. Not only are the masks multicolored, they’re also amazing for the skin. Plus, they’re the best way to create the glitter-face look seen at the Giambattista Valli Paris fall 20018 runway show, while helping your skin look rejuvenated.

Why We Don’t Need the Government to Protect Us from “Polarizing” Internet Speech 

Cass Sunstein has been for some time a capable and influential critic of individual choice and limited government. Over the past decade, he has argued that the Internet is failing liberal democracy. Left to their own preferences, he says, individuals choose to avoid political views that challenge their prior beliefs. They form filter bubbles that exclude contrary views and echo chambers that polarize debates. Both complicate solving national problems.These alleged filter bubbles and echo chambers comprise expressing and hearing (or reading) speech, both highly protected activities in the United States (or in any polity deserving the name liberal). The harms of filter bubbles and echo chambers should be much more than alleged to justify government actions to “improve” our debates.What Do the Data Say?Sunstein’s claims about filter bubbles and echo chambers have a certain appeal. We can imagine people choosing to avoid unpleasant people and views. As communications researcher Cristian Vaccari notes:

Men reportedly attacked by stranger armed with tire iron over ‘Pokemon Go’ game

– Three men were relaxing on a park bench in Vancouver when they say a stranger pulled up in a car and attacked them with a tire iron, apparently upset over a “Pokemon Go” game.Andrew Otton and two of his friends were hanging out at Vancouver’s Burnt Bridge Creek Trail when a stranger reportedly parked his car and started charging at them.”He comes out of nowhere, yelling, ‘Which one of you is Andy?’ with a tire iron in his hand,” Otton said. “My username is AndySamberg, so he was looking for the Andy guy and I was just reviving my Pokemon when he was trying to take it out. I took it from him and I didn’t know he just took it, and he was like, ‘Hey, did you just take this gym from me? That’s pretty messed up, man.’ He was very angrily saying it.”

Lockheed Shares Satellite Connectivity Options

In an unusual turn of events, Lockheed Martin has released technical “payload accommodation information” for three of their satellite busses. In layperson’s terms, if you wanted to build a satellite and weren’t sure what guidelines to follow these documents may help you learn if Lockheed Martin has a platform to help you build it.An opportunity to check out once-confidential information about satellites sounds like a perfect excuse to dig through some juicy documentation, though unfortunately this may not be the bonanza of technical tidbits the Hackaday reader is looking for. Past the slick diagrams of typical satellites in rocket fairings, the three documents in question primarily provide broad guidance. There are notes about maximum power ratings, mass and volume guidelines, available orbits, and the like. Communication bus options are varied; there aren’t 1000BASE-T Ethernet drops but multiply redundant MIL-STD-1553B might come standard, plus telemetry options for analog, serial, and other data sources up to 100 Mbps. Somewhat more usual (compared to your average PIC32 datasheet) are specifications for radiation shielding and it’s effectiveness.
