Atlas 5 Rocket Launches $400 Million NASA Satellite Into Space

Slashdot - Sat, 08/19/2017 - 05:00
A new communications hub has been successfully deployed in space today thanks to the United Launch Alliance Atlas 5 rocket. "TDRS is a critical national asset have because of its importance to the space station and all of our science missions, primarily the Hubble Space Telescope and Earth science missions that use TDRS," said Tim Dunn, NASA's TDRS-M launch director. Spaceflight Now reports: With its main engine running at full throttle, the Atlas 5 booster lifted off at 8:29 a.m. EDT (1229 GMT) from Complex 41 at Cape Canaveral. The 191-foot-tall rocket, generating 860,000 pounds of thrust, aimed eastward and accelerated out of the atmosphere with NASA's TDRS-M spacecraft. Within just five minutes, the rocket had shed 92 percent of its liftoff weight and transitioned to the high-energy Centaur upper stage. An elliptical parking orbit was achieved within 18 minutes of takeoff, beginning a 90-minute quiescent coast higher through space to reach the optimum conditions for the second burn by Centaur. That minute-long boost over the Indian Ocean propelled the 7,610-pound payload into a customized high-perigee geosynchronous transfer orbit. The spacecraft was deployed by the launcher at T+plus 1 hour, 53 minutes to cheers and handshakes all around. The $408 million TDRS-M was built and launched with the sole purpose to extend the useful life of NASA's constant communications infrastructure, supporting the astronauts around-the-clock aboard the International Space Station, supplying contact with the Hubble Space Telescope and transmitting the data from almost 40 science spacecraft studying Earth's environment and space.

Is Sugar From Fruit The Same As Sugar From Candy?

AdaFruit - Sat, 08/19/2017 - 04:00


With all health concerns circulating about sugar there is some confusion about fruit. Fruit is undoubtedly a high sugar food but is it the same? Via NPR:

No, sugar in fruit and added sugar is not the same thing, says Lauri Wright, a nutritionist, public health specialist, and spokesperson for the Academy of Nutrition and Dietetics.

There are lots of kinds of sugar. Fruits have fructose, glucose, and a combination of the two called “sucrose,” or “table sugar.” But the sugars in fruit are packed less densely than in a candy bar, according to Elvira Isganaitis, a pediatric endocrinologist at Joslin Diabetes Center and a Harvard Medical School instructor.

A can of soda, for example, has about 40 grams of sugar. “And what else are you getting with that?” Wright asks. “You’re getting no protein, no minerals, and no fiber. You get nothing but the sugar and the calories.”

A serving of fruit, by contrast, usually contains no more than 20 grams of sugar, has fiber, and has nutrients like vitamin C. As Wright puts it: “You’re getting a lot of bang for your buck.” And fiber and lower sugar amounts can also decrease sugar spikes in blood levels.

Mat Collishaw Talks Thresholds with VMI Studio #VirtualReality #celebratephotography

AdaFruit - Sat, 08/19/2017 - 03:00

Interview excerpt from VMI Studio:

Michele Baker: Let’s start by talking about the exhibition itself. Can you tell me a little more about Thresholds? What does the piece involve?

Mat Collishaw: Thresholds is a VR project. It’s quite a specific virtual reality project, involving a lot of other sensory stimulation, such as haptic interaction. The warmth from the fire is created by a heater, and we are also bringing smells in there, as well as, of course, the scene outside the window.

I work in a lot of different media anyway; paintings and laser scanning, for example, so VR was an obvious thing to work with. Though I am not really a techie person, this medium can give you a 360-degree full immersion in the image, obviously something that needs addressing if you’re an artist, I think.

But I wanted a project that was interesting as an idea, not just a magic forest with unicorns and little elves running around, or a documentary film. I wanted to make something that was a concept, because I am a conceptual artist, although my work is very accessible.

The Hasselquad is an Analog Aerial Photography Platform #celebratephotography

AdaFruit - Sat, 08/19/2017 - 02:00

Great ongoing project from Richard Hogben:

Medium format film photography from a quadcopter. Including the shutter remote trigger and the FPV viewfinder module using mostly off-the-shelf components.

What’s already completed:

  • Quadcopter, these are a commodity and will not be going into too much detail.
  • Camera mount, currently fixed until I decide I have to have a gimbal for straight horizons.
  • Remote shutter, the camera I’m using has an electronically controlled shutter. This was easy to trigger from the radio receiver.
  • FPV viewfinder

Google and ProPublica Team Up To Build a National Hate Crime Database

Slashdot - Sat, 08/19/2017 - 02:00
In partnership with ProPublica, Google News Lab is launching a new tool to track hate crimes across America. The "Documenting Hate News Index" is being powered by machine learning to track reported hate crimes across all 50 states, collecting data from February 2017 onward. TechCrunch reports: Data visualization studio Pitch Interactive helped craft the index, which collects Google News results and filters them through Google's natural language analysis to extract geographic and contextual information. Because they are not catalogued in any kind of formal national database, a fact that inspired the creation of the index to begin with, Google calls the project a "starting point" for the documentation and study of hate crimes. While the FBI is legally required to document hate crimes at the federal level, state and local authorities often fail to report their own incidents, making the data incomplete at best. The initiative is a data-rich new arm of the Documenting Hate project which collects and verifies hate incidents reported by both individual contributors and by news organizations. The Hate News Index will keep an eye out for false positives (casual uses of the word "hate" for example), striking a responsible balance between machine learning and human curation on a very sensitive subject. Hate events will be mapped onto a calendar in the user interface, though users can also use a keyword search or browse through algorithmic suggestions. For anyone who'd like to take the data in a new direction, Google will open sourced its data set, making it available through GitHub.

How Hackers Can Use Pop Songs To 'Watch' You

Slashdot - Fri, 08/18/2017 - 22:30
An anonymous reader quotes a report from Fast Company: Forget your classic listening device: Researchers at the University of Washington have demonstrated that phones, smart TVs, Amazon Echo-like assistants, and other devices equipped with speakers and microphones could be used by hackers as clandestine sonar "bugs" capable of tracking your location in a room. Their system, called CovertBand, emits high-pitched sonar signals hidden within popular songs -- their examples include songs by Michael Jackson and Justin Timberlake -- then records them with the machine's microphone to detect people's activities. Jumping, walking, and "supine pelvic tilts" all produce distinguishable patterns, they say in a paper. (Of course, someone who hacked the microphone on a smart TV or computer could likely listen to its users, as well.)

Hyundai To Build a 300-Mile-Per-Charge Electric Car

Slashdot - Fri, 08/18/2017 - 20:45
On Thursday, Hyundai Motor said it will launch a long-range electric vehicle with a driving range of 500 km (311 miles) per charge after 2021. The company is reportedly planning 31 eco-friendly models by 2020, up from a previously flagged 28. Reuters reports: The South Korean automaker is planning to launch an electric sedan under its high-end Genesis brand in 2021 with a range of 500 km (310 miles) per charge. It will also introduce an electric version of its Kona small sport utility vehicle (SUV) with a range of 390 km in the first half of next year. The automaker and affiliate Kia Motors Corp, which together rank fifth in global vehicle sales, also said they were adding three plug-in vehicles to their plans for eco-friendly cars, bringing the total to 31 models by 2020. Underscoring Hyundai's electric shift, those plans include eight battery-powered and two fuel-cell vehicles -- a contrast to its 2014 announcement for 22 models, of which only two were slated to be battery-powered. Hyundai also confirmed a Reuters report that it is developing its first dedicated electric vehicle platform, which will allow the company to produce multiple models with longer driving ranges.

Memories of Fear Could Be Permanently Erased, Study Shows

Slashdot - Fri, 08/18/2017 - 20:05
A new study unpicks why certain sounds can stir alarming memories, and reveals a new approach to wiping such memories from the brain. The Guardian reports: Published in the journal Neuron by Cho and his colleague Woong Bin Kim, the research reveals how the team used genetically modified mice to examine the pathways between the area of the brain involved in processing a particular sound and the area involved in emotional memories, known as the amygdala. In the first part of the experiment the team played both a high pitched and low-pitched tone to mice. But, when the high-pitched sound was played, the researchers also gave the mice a small electric shock to their feet. When the high-pitched tone was subsequently played on its own, the mice froze in fear; no such response was seen when the alternative, low-pitched, tone was played. The team then looked to see if there were differences between the high-pitch and low-pitch tone pathways in the brains of the mice, revealing that, among the mice exposed electric shocks, the connections within the "high-pitched" pathway had become stronger, while the other pathway remained unchanged. The team found that when mice were subsequently repeatedly exposed to high-pitched sounds without the shocks they lost their fear -- a process known as fear extinction. But the team discovered that using a technique called optogenetics, it was possible to truly erase the unpleasant memories. This technique involved the researchers using a virus to introduce genes into particular neurons in the brains of the mice that were involved in the "high-pitch" pathways. Once inside the cells, the genes result in the production of proteins which respond to light, allowing researchers to control the activity of the neurons. Taking mice with the fearful memories, the team exposed the neurons involved in the "high-pitch" pathway to low-frequency light -- an approach which weakens the connections between the neurons. The upshot was that the mice no longer appeared fearful when they heard the high-pitched tone.

Android O Is Officially Launching August 21

Slashdot - Fri, 08/18/2017 - 19:35
Android O is set to arrive on August 21, with a livestreamed unveiling event timed for 2:40 PM ET in NYC -- which is roughly when the maximum solar eclipse is set to occur for New York. TechCrunch reports: Android O will get a full reveal at that time, which seems like kind of a weird time to do it since a lot of people will be watching the NASA eclipse livestream that Google is also promoting, or staring at the sky (with the caveat, hopefully, that they have procured proper glasses for safe viewing). Google says that Android O will have some "super (sweet) new powers," most of which we know all about thanks to pre-release builds and the Android O teaser Google provided at its annual I/O developer event this past May. WE know, for instance, that the notification panel has been changed significantly, and there's new optimization software to improve battery life on all devices. While Android O's name has yet to be confirmed, the official consumer name is speculated to be "Oreo." Prolific leaker Evan Blass posted a picture of an Oreo to Twitter on Friday following the announcement of the reveal date and event.

US Military To Create Separate Unified Cyber Warfare Command

Slashdot - Fri, 08/18/2017 - 19:05
wiredmikey quotes a report from SecurityWeek: President Donald Trump has ordered the U.S. military to elevate its cyber warfare operations to a separate command, signaling a new strategic emphasis on electronic and online offensive and defensive operations. "I have directed that United States Cyber Command be elevated to the status of a Unified Combatant Command focused on cyberspace operations," Trump said in a statement Friday. The move would expand the number of the Defense Department's unified combatant commands to 10, putting cyber warfare on an equal footing with the Strategic Command, the Special Operations Command, and regional commands. Until now cyber warfare operations have been run under the umbrella of the National Security Agency, the country's main electronic spying agency, with Admiral Michael Rogers heading both.

Waymo Patent Shows Plans To Replace Steering Wheel, Pedals With Push Button

This reflects Alphabet's driverless arm could remain true to its original mantra of developing cars that pilot themselves without human intervention.

Google Explains Why It Banned the App For Gab, a Right-Wing Twitter Rival

Slashdot - Fri, 08/18/2017 - 17:40
AmiMoJo shares a report from Ars Technica: When right-wing trolls and outright racists get kicked off of Twitter, they often move to Gab, a right-wing Twitter competitor. Gab was founded by Andrew Torba, who says it's devoted to unfettered free expression online. The site also hosts controversial right-wing figures like Milo Yiannopoulos, Andrew 'weev' Auernheimer and Andrew Anglin, editor of the neo-Nazi site Daily Stormer. On Thursday, Gab said that Google had banned its Android app from the Google Play Store for violating Google's ban on hate speech. The app's main competitor, Twitter, hosts accounts like the American Nazi Party, the Ku Klux Klan, and the virulently anti-gay Westboro Baptist Church, yet the Twitter app is still available on the Google Play store. Apple has long had more restrictive app store policies, and it originally rejected the Gab app for allowing pornographic content to be posted on the service -- despite the fact that hardcore pornography is readily available on Twitter. In an email to Ars, Google explained its decision to remove Gab from the Play Store: "In order to be on the Play Store, social networking apps need to demonstrate a sufficient level of moderation, including for content that encourages violence and advocates hate against groups of people. This is a long-standing rule and clearly stated in our developer policies. Developers always have the opportunity to appeal a suspension and may have their apps reinstated if they've addressed the policy violations and are compliant with our Developer Program Policies."
