Submission + - Robots learn by watching YouTube videos (cornell.edu)

aurtherdent2000 writes: When you hire new workers you might sit them down to watch an instructional video on how to do the job. What happens when you buy a new robot?

Faced with an unfamiliar task, the robot’s computer brain begins by sending a query to YouTube to find a collection of how-to videos on the topic. By scanning multiple videos on the same task, a computer can find what they all have in common using unsupervised machine learning. Part of what makes it possible is that there is a common underlying structure to most how-to videos. And, there’s plenty of source material available. YouTube offers 180,000 videos on “How to make an omelet” and 281,000 on “How to tie a bowtie.” Cornell and Stanford researchers call this project RoboWatch

Submission + - CUP OF JAVASCRIPT: This roboservant will learn how to make you coffee

aurtherdent2000 writes: In the future, we will have roboservants to do our bidding. At least that’s the promise. Right now, roombas are as close as we’ve come to having machines do our chores, and they’re a far cry from Rosie from the Jetsons. Scientists at Cornell University are trying to change that by developing deep learning algorithms (a 'collective brain of the human crowd') that allows a robot to use different types of appliances, like juice makers, espresso machines, microwave, cereal dispensers, and sinks based on common parts. Maybe one day, Folger’s jingle will say that the best part of waking up is a robot making your cup.

Get your first look at the new Star Wars: The Force Awakens teaser #2!

Lucasfilm and visionary director J.J. Abrams join forces to take you back again to a galaxy far, far away as “Star Wars” returns to the big screen with “Star Wars: The Force Awakens.”

Episode VII in the Star Wars Saga, Star Wars: The Force Awakens, opens in theaters December 18, 2015.

Submission + - An engineering analysis of the Falcon 9 first stage landing failure

schwit1 writes: Link here.

SpaceX founder and chief technology officer Elon Musk tweeted that "excess lateral velocity caused it [the booster] to tip over post landing." In a later tweet that was subsequently withdrawn, Musk then indicated that "the issue was stiction in the biprop throttle valve, resulting in control system phase lag." In this statement, Musk was referring to "stiction" — or static friction — in the valve controlling the throttling of the engine. The friction appears to have momentarily slowed the response of the engine, causing the control system to command more of an extreme reaction from the propulsion system than was required. As a result, the control system entered a form of hysteresis, a condition in which the control response lags behind changes in the effect causing it.

Despite the failure of the latest attempt, SpaceX will be encouraged by the landing accuracy of the Falcon 9 and the bigger-picture success of its guidance, navigation and control (GNC) system in bringing the booster back to the drone ship. The GNC also worked as designed during the prior landing attempt in January, which ended in the destruction of the vehicle following a hard touchdown on the edge of the platform.

Submission + - Dark Matter May Not Be Completely Dark

StartsWithABang writes: If you take two clusters, groups, or individual galaxies and collide them together, you'd expect the stars to pass through unperturbed, the gas to experience friction, slowing down and heating up, while the dark matter, if it's truly collisionless, will do the same thing as the stars. But if there's a tiny frictional force at work on dark matter, it, too, will slow down a little bit. A team looking at 72 groups and clusters saw no effect of slowing down, but then on the 73rd one, they saw a separation between the mass reconstruction and the stars. Is this the first sign of dark matter's interactions, or is it simply an astrophysical effect, or maybe even a fluke? A good recap and rundown of what we're looking at to the best of our knowledge.

Submission + - The car that knows when you'll get in an accident before you do (fusion.net)

aurtherdent2000 writes: I’m behind the wheel of the car of the future. It’s a gray Toyota Camry, but it has a camera pointed at me from the corner of the windshield recording my every eye movement, a GPS tracker, an outside-facing camera and a speed logger. It sees everything I’m doing so it can predict what I’m going to do behind the wheel seconds before I do it. So when my eyes glance to the left, it could warn me there’s a car between me and the exit I want to take.

Submission + - Spitzer Space Telescope Finds New Planet (brevardtimes.com)

Aspiring Astronomer writes: Astronomers discover a gas planet 13,000 light-years away in our galaxy by using NASA's Spitzer Space Telescope. This newfound planet is one of the most distant planets known, as it is located much closer to our galaxy's central disk than our solar system.
The telescope was able to determine an approximate distance of this planet by joining techniques of microlensing and parallax to create a measurement for the planet. This combined the use of a ground telescope in Chile with NASA's Spitzer Space Telescope. Knowing the distance of this newly discovered planet helps scientists calculate the mass of the planet, which is about half that of Jupiter.

Submission + - Maps Offer New View Into Dark Matter (thesilverink.com)

Aspiring Astronomer writes: High resolution maps released Monday show that dark and light often cluster close together in the universe. New studies have shown that large amounts of dark matter are heavily concentrated in some areas, yet nonexistent in others. Research shows that groups of galaxies tend to be located near large amounts of dark matter. Theories suggest that dark matter's powerful gravitational force pulls in regular matter, bringing the dark and light universe together.

Cornell University's Robobarista project uses online crowd-sourced games (http://robobarista.cs.cornell.edu), and uses deep learning to teach robots how to perform tasks reading from a recipe.

Submission + - SpaceX Dragon launches successfully but no rocket recovery

monkeyzoo writes: SpaceX has successfully launched a Falcon 9 rocket carrying a SpaceX Dragon spacecraft en route to the International Space Station with supplies (including an Italian espresso machine). This was also the second attempt to recover the launch rocket aboard a ship, but that apparently was not successful. Elon Musk tweeted that the rocket landed on the recovery ship but too hard to be reused.

Submission + - Plans to Build a Massive Online Brain for the Robots

aurtherdent2000 writes: Wired reports that four universities (Stanford, Cornell, Brown and UC Berkeley) plan to build a massive online Robo Brain that will learn from the data on the Internet and from physical interactions of the real-world robots. The robots can query the brain about information just like one can query search engines for engines.

Submission + - Toward a Quantum Theory of Gravity? (huffingtonpost.com)

GlowingCat writes: One of the main problems in attempting to calculate gravitational interactions with gravitons has been that the calculations produced unphysical infinities at almost every step. Bern and colleagues, however, managed to enormously simplify the calculations by showing that, at least in some cases, gravitons can be replaced by two copies of gluons — the carriers of the strong nuclear force. If this double-copy-of-gluons relationship holds in general, this clue could potentially lead to a dramatic breakthrough in the search for a quantum theory of gravity.

Submission + - Extending human vision range into near-infrared with Vitamin A

asvravi writes: A crowd-funded experiment on experiment.com seeks to extend the color range of human vision into near infra-red by only manipulating the amounts of vitamin A1 and A2 in the diet of subjects.
It has now reported initial success with human eye response at 950nm as compared to 850nm before the diet modifications. https://experiment.com/u/aAcR2...
How long until full night vision?
