Vast Web of Dark Matter Mapped 86

Posted by Soulskill from the here-there-be-dragons dept.
astroengine writes "Astronomers from the University of British Columbia and University of Edinburgh have created a vast cosmic map revealing an intricate web of dark matter and galaxies spanning a distance of one billion light-years. This is the largest map of its kind and demonstrates that this large-scale web stretches across the universe in all directions. The results of this groundbreaking discovery were presented at the American Astronomical Society conference in Austin, Texas on Monday."

Samsung Could Soon Start To Twist Google's Arm 214

Posted by Soulskill from the no-more-mister-nice-guy dept.
Hugh Pickens writes "For the past three years, Android has experienced a kind of free space expansion, but as we enter 2012, it seems the game may be changing. Instead of the old 'there's more than enough room for every Android handset maker to be a winner,' we have a three-horse's-length leader: Samsung shipping close to 55% of all Android phones, while Motorola and HTC lag behind. '[Samsung] could be in a position to twist Google's arm,' writes Jean-Louis Gassée.'If last quarter's trend continues — if Motorola and HTC lose even more ground — Samsung's bargaining position will become even stronger.' But what is Samsung's 'bargaining position'? What could they want? Perhaps more search referral money, earlier access to Android releases, or a share of advertising revenue. Will Google let Samsung gain the upper hand? It's not likely, because Motorola is about to become a fully-owned but 'independent' Google subsidiary, and its 16% of the Android market could counterbalance Samsung's influence to some extent. So what could Samsung do? 'Consider the Kindle Fire example: Just like Amazon picked the Android lock, Samsung could grab the Android Open Source code and create its own unlicensed but fully legal smartphone OS and still benefit from a portion of Android apps, or it could build its own app store the way Amazon did,' writes Gassée. 'Samsung is a tough, determined fighter and won't let Google dictate its future. The same can be said of Google. This is going to be interesting.'"

Data Hogs: the Monsters Carriers Created 215

Posted by Soulskill from the it's-a-car-analogy dept.
jfruhlinger writes "A recent study claimed that the top 1 percent of mobile data users eat up half of the available bandwidth. But assuming it's true, who's at fault? Stats show data usage has increased radically with each new model of the iPhone, and similar phenomena are in place for Android phones — all of which are gleefully sold to the public by the same people who complain about 'data hogs.' Isn't this the equivalent of a car dealer heavily promoting Cadillacs, then complaining about poor fuel efficiency, then charging a ton for extra gasoline?"

Salmon DNA Used In Data Storage Device 51

Posted by Soulskill from the also-tastes-great-on-the-grill dept.
Zothecula writes "Scientists from National Tsing Hua University in Taiwan and the Karlsruhe Institute of Technology in Germany have created a 'write-once-read-many-times' (WORM) memory device that combines electrodes, silver nanoparticles, and salmon DNA. While the current device is simply a proof-of-concept model, the researchers have stated that DNA could turn out to be a less expensive alternative to traditional inorganic materials such as silicon."

Video Games As Propaganda 251

Posted by Soulskill from the koopa-troopas-are-terrorists dept.
SharkLaser writes "A video game developer working for Kuma Reality Games has admitted that the company has been receiving money from the CIA to design and freely distribute special movies and games with the aim of manipulating public opinion in the Middle East. Amir Mizra Hekmati, a former U.S. Marine, moved to work for Kuma after working for DARPA and has said the goal of the company was to convince people that whatever the U.S. does in other countries is a good measure. Kuma officials have declined to comment, while Hekmati himself is locked in Iran. The United States government has demanded the release of Hekmati, but Iran has sentenced him to death for spying, which he confessed to."

Carbon Emissions 'Will Defer Ice Age' 347

Posted by Soulskill from the not-cool dept.
Sven-Erik writes "Due to subtle variations in the Earth's orbit, researchers have calculated that the next Ice Age is due within 1,500 years. However, a new study suggests greenhouse gas emissions mean it will not happen that soon (abstract). 'Dr Skinner's group ... calculates that the atmospheric concentration of CO2 would have to fall below about 240 parts per million (ppm) before the glaciation could begin. The current level is around 390ppm. Other research groups have shown that even if emissions were shut off instantly, concentrations would remain elevated for at least 1,000 years, with enough heat stored in the oceans potentially to cause significant melting of polar ice and sea level rise.'"

What Does Sunset On an Alien World Look Like? 94

Posted by Soulskill from the forgot-my-camera dept.
The Bad Astronomer writes "Using real data from Hubble Space Telescope of a planet orbiting another star, exoplanetary scientist Frédéric Pont created a lovely image of what sunset would look like from HD209458b, nicknamed Osiris, a planet 150 light years away. The Hubble data gave information on the atmospheric absorption of this hot Jupiter planet, and, coupled with models of how the atmosphere was layered, Pont was able to create a realistic looking sunset on the planet. The big surprise: the star looks green as it sets! Sodium absorption sucks out the red colors and blue is scattered away, leaving just the green hues to get through. It's a lovely application of hard scientific knowledge."

Could a Dirty Rag Take Out a $2 Billion Satellite? 297

Posted by Soulskill from the dumb-mistakes-cost-the-most dept.
An anonymous reader writes "The alleged rescue of a U.S. military communications satellite underscores some of the weaknesses in U.S. space efforts. Quoting: 'The seven-ton “AEHF-1,” part of a planned six-satellite constellation meant to support radio communication between far-flung U.S. military units, had been in orbit just one day when the problems began. The satellite started out in a highly-elliptical, temporary orbit. The plan was to use the spacecraft’s on-board engine to boost it to a permanent, geo-stationary orbit. But when the Air Force space operators at Los Angeles Air Force Base activated the engine, nothing happened. The Government Accountability Office would later blame the failure on a rag left inside a fuel line by a Lockheed worker.'"

The Challenges of Building a Mars Base 228

Posted by Unknown Lamer from the needs-a-jacuzzi dept.
ambermichelle writes with an excerpt from an article in Txchnologist: "Going to Mars? Expect to stay a while. Because of the relative motions of Earth and Mars, the pioneering astronauts who touch down on the Martian surface will have to remain there for a year and a half. For this reason, NASA has already started experimenting with a habitat fit for the long-term exploration of Mars. Last year, students at the University of Wisconsin won the XHab competition to design and build an inflatable loft addition to a habitat shell that NASA had already constructed. The final structure now serves as a working model that is being tested in the Arizona desert. Like any home, it's a sacred bulwark against the elements; but not just the cold, heat, and pests of Arizona. A Mars habitat will have to protect astronauts from cosmic rays, solar flares, and unknown soil compositions all while keeping inhabitants happy and comfortable."

Researchers Show How Cellular Complexity Can Evolve 140

Posted by Unknown Lamer from the cellular-reverse-engineering dept.
ananyo writes with an excerpt from a Nature news release: "By bringing long-dead proteins back to life, researchers have worked out the process by which evolution added a component to a cellular machine. ... In a paper published in Nature, researchers recreated an 'ancestral' version of a cellular machine called the V-ATPase proton pump, which channels protons across membranes and is vital for keeping cell compartments at the right acidity. Part of this machine is a ring of six proteins that threads through the membrane. Animals and most other eukaryotes have a ring composed of two types of protein component; fungi are alone in having a ring with three. The researchers used computational methods to work backwards and find the most likely sequences of these proteins hundreds of millions of years ago. The team inserted the DNA into yeast and found that just two mutations can turn the simple 2-protein ring into the more complex 3-protein ring."

Google Accused of Interfering With South Korean FTC Investigation 186

Posted by Unknown Lamer from the only-do-evil-occasionally dept.
New submitter DCTech writes "South Korea's Fair Trade Commission is accusing Google of methodically interfering with an anti-competition investigation into Android. 'Google deleted files and made its employees work from home in an attempt to frustrate the investigation, alleges the commission in an interview with a South Korean newspaper [machine translation]. The non-cooperation allegedly came after Google's Seoul office was raided by the commission's officials in September. The anti-competition probers were looking into whether Google's Android phones unfairly prioritize Google search and are "systematically designed" to make it difficult to switch to another option'. Now the South Korean watchdog is considering maximum fines for Google's non-compliance. Google is currently under investigation for similar anti-competition issues in Europe and the U.S."

New Research Shows Cognitive Decline Begins At 45 295

Posted by Unknown Lamer from the shares-in-soylent-green-up dept.
An anonymous reader writes "New research shows people might start to suffer from cognitive decline as early as age 45. The research, which looked at over 7000 people between the ages of 45 and 70 when the study started, watched participants over a 10 year period. Disturbingly enough, even the youngest participants started declining immediately."
