Submission + - Scientists Find Radioactive Aircraft Carrier Off California Coast

HughPickens.com writes: Aaron Kinney writes in the San Jose Mercury News that scientists have captured the first clear images of the USS Independence, a radioactivity-polluted World War II aircraft carrier that rests on the ocean floor 30 miles off the coast of Half Moon Bay. The Independence saw combat at Wake Island and other decisive battles against Japan in 1944 and 1945 and was later blasted with radiation in two South Pacific nuclear tests. Assigned as a target vessel for the Operation Crossroads atomic bomb tests, she was placed within one-half-mile of ground zero and was engulfed in a fireball and heavily damaged during the 1946 nuclear weapons tests at Bikini Atoll. The veteran ship did not sink, however (though her funnels and island were crumpled by the blast), and after taking part in another explosion on 25 July, the highly radioactive hull was later taken to Pearl Harbor and San Francisco for further tests and was finally scuttled off the coast of San Francisco, California, on 29 January 1951. "This ship is an evocative artifact of the dawn of the atomic age, when we began to learn the nature of the genie we'd uncorked from the bottle," says James Delgado. "It speaks to the 'Greatest Generation' — people's fathers, grandfathers, uncles and brothers who served on these ships, who flew off those decks and what they did to turn the tide in the Pacific war."

Delgado says he doesn't know how many drums of radioactive material are buried within the ship — perhaps a few hundred. But he is doubtful that they pose any health or environmental risk. The barrels were filled with concrete and sealed in the ship's engine and boiler rooms, which were protected by thick walls of steel. The carrier itself was clearly "hot" when it went down and and it was packed full of fresh fission products and other radiological waste at the time it sank. The Independence was scuttled in what is now the Gulf of the Farallones sanctuary, a haven for wildlife, from white sharks to elephant seals and whales. Despite its history as a dumping ground Richard Charter says the radioactive waste is a relic of a dark age before the enviornmental movement took hold. "It's just one of those things that humans rather stupidly did in the past that we can't retroactively fix."

Submission + - Security expert pulled off flight by FBI after exposing aircraft vulnerabilities (foxnews.com)

schwit1 writes: One of the world's foremost experts on counter-threat intelligence within the cybersecurity industry, who blew the whistle on vulnerabilities in airplane technology systems in a series of recent Fox News reports, has become the target of an FBI investigation himself.

Chris Roberts of the Colorado-based One World Labs, a security intelligence firm that identifies risks before they're exploited, said two FBI agents and two uniformed police officers pulled him off a United Airlines Boeing 737-800 commercial flight Wednesday night just after it landed in Syracuse, and spent the next four hours questioning him about cyberhacking of planes.

Submission + - Earth microbe prefers living on meteorites (sciencemag.org)

sciencehabit writes: Scientists have found a microbe that is happier living on meteorites than on Earth. The organism—an archaea known as Metallosphaera sedula—was originally found in 1989 living in Italy's hot acidic sulfur springs around Vesuvius. When the researchers gave them an energy drink made of powdered meteorite, the microbes went on a space dust binge—consuming their samples in only 2 weeks as compared with the 2 months it took for them to munch through their Earth samples. The team says its work could have implications for asteroid mining, where rare metals embedded in space rocks could be extracted and brought back to Earth for use in technological advancements.

An anonymous reader writes: Research reveals that all major browsers leak data that can reveal a users location to third parties down to their country, city, neighborhood, and address. A "geo-inference" attack measures browser cache queries and uses location-sensitive data left by websites like Google or Craigslist or a full 62% of Alexa's top 100 websites in five countries.

Submission + - How many hoaxes are on Wikipedia? No one knows.... 2

An anonymous reader writes: The Washington Post's Caitlin Dewey has written a lengthy feature covering one of Wikipedia's most intractable problems: carefully inserted hoax information that is almost impossible to detect. Dewey's investigation starts with the recent discovery of the nonexistent Australian god "Jar’Edo Wens" (which lasted almost ten years), and discusses a Wikipediocracy post about a recent experiment by critic Greg Kohs, in which 30 articles received cleverly-chosen minor falsehoods. More than half survived for more than two months. Included is also a chart showing that editing participation in Wikipedia has "atrophied" since 2007. It is quite rare to see a feature in a major media outlet as critical as this, of Wikipedia and its little-known internal problems. Especially on the heels of a very favorable CBS 60 Minutes report. As Kohs says, “I think this has proved, beyond a reasonable doubt, that it’s not fair to say Wikipedia is ‘self-correcting,’”

schwit1 writes: It's small. It's bright yellow, and it's capable of cracking Wi-Fi passwords, eavesdropping on your cell phone calls and reading your text messages. It's a spy drone and it just landed in Washington, D.C.

Long-time friends and former Air Force buddies, Mike Tassey and Rich Perkins, describe their state-of-the-art cyber drone as hard to take down, hard to see and virtually hard to detect.

They built it in a garage, using off the shelf electronics to prove a drone can be used to launch cyber-attacks.

Submission + - Cosmic Mystery Solved? Possible Dark Matter Signal Spotted (space.com)

TaleSlinger writes: Astronomers may finally have detected a signal of dark matter, the mysterious and elusive stuff thought to make up most of the material universe.

While poring over data collected by the European Space Agency's XMM-Newton spacecraft, a team of researchers spotted an odd spike in X-ray emissions coming from two different celestial objects — the Andromeda galaxy and the Perseus galaxy cluster.

  "The signal's distribution within the galaxy corresponds exactly to what we were expecting with dark matter — that is, concentrated and intense in the center of objects and weaker and diffuse on the edges," [assuming that dark matter consists of sterile neutrinos] study co-author Oleg Ruchayskiy, of the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland, said in a statement.

"With the goal of verifying our findings, we then looked at data from our own galaxy, the Milky Way, and made the same observations," added lead author Alexey Boyarsky, of EPFL and Leiden University in the Netherlands.

  Researchers have proposed a number of different exotic particles as the constituents of dark matter, including weakly interacting massive particles (WIMPs), axions and sterile neutrinos, hypothetical cousins of "ordinary" neutrinos (confirmed particles that resemble electrons but lack an electrical charge).

The decay of sterile neutrinos is thought to produce X-rays, so the research team suspects these may be the dark matter particles responsible for the mysterious signal coming from Andromeda and the Perseus cluster.

Submission + - Who Must You Trust? (acm.org)

CowboyRobot writes: In ACM's Queue, Thomas Wadlow argues that "Whom you trust, what you trust them with, and how much you trust them are at the center of the Internet today."
He gives a checklist of what to look for when evaluating any system for trustworthiness, chock full of fascinating historical examples.
These include NASA opting for a simpler, but more reliable chip; the Terry Childs case; and even an 18th century "semaphore telegraph" that was a very early example of steganographic cryptography.
FTA: "Detecting an anomaly is one thing, but following up on what you've detected is at least as important. In the early days of the Internet, Cliff Stoll, then a graduate student at Lawrence Berkeley Laboratories in California, noticed a 75-cent accounting error on some computer systems he was managing. Many would have ignored it, but it bothered him enough to track it down. That investigation led, step by step, to the discovery of an attacker named Markus Hess, who was arrested, tried, and convicted of espionage and selling information to the Soviet KGB."

Submission + - High Frequency Trading and Finance's Race to Irrelevance

hype7 writes: The Harvard Business Review is running a fascinating article on how finance is increasingly abstracting itself — and the gains it makes — away from the creation of value in the real world, and how High Frequency Trading is the most extreme version of this phenomenon yet. From the article: High frequency trading is a different phenomenon from the increasing focus on short term returns by human investors. But they’re borne from a similar mindset: one in which financial returns are the priority, independent of whether they’re associated with something innovative or useful in the real world. What Lewis’s book demonstrated to me isn’t just how “bad” HFTs are per se, but rather, what happens when finance keeps walking down the path it seems to be set on — a path that involves abstracting itself from the creation of real-world value. The final destination? It will enter a world entirely of its own — a world in which it is fighting to capture value that is completely independent of whether any is created in the first place.

Submission + - Kleargear.com found in Europe, will fight default judgement

portforward writes: Remember Kleargear.com, that company who bills unhappy customers $3,500 for publicly expressing they are unhappy? Kleargear.com claimed they were owed a substantial amount of money after a couple posted their negative experience on RipoffReport.com and then attempted to collect, severly damaging the the family's credit rating. The unlucky couple sued, and got a default judgement against Kleargear in part because no one could actually find the owners of the company. Apparently now the owners have surfaced in Paris — vowing to fight and saying:

"Our sales contract is enforceable under the laws of the United States because business transactions are exempt from First Amendment rights ... If a customer disagrees with any merchant of policies, they are free to shop elsewhere."

Especially, of course, when the company adds conditions to the bill of sale after the sale is complete.

Submission + - Cinavia defeated (torrentfreak.com)

Hamsterdan writes: Cinavia's anti-piracy technology has been a thorn in the side of many file-sharers, who are unable to pay pirated files on their DVD-players without being interrupted by a warning message. In a breakthrough development, software vendor DVD-Ranger has cracked the protection, including for popular movies downloaded from pirate sites.

Cinavia’s anti-piracy technology relies on a unique type of watermarking that allows it to remain present in pirated movies despite re-recording, transcoding, compression, or other type of transfer.

jfruh writes: Good news for HP: Profits are up by 18% over the previous year! Bad news for HP: A lot of those profits are from post-Windows XP PC upgrades, and company revenue actually dipped 1%. The solution, according to CEO Meg Whitman, is "continuous improvement in our cost structure," which means firing thousands of people. At the end of the next round of layoffs, the company will have shed 50,000 employees since 2012.
