Submission + - Resistance to antibiotics found in isolated Amazonian tribe (sciencemag.org)

sciencehabit writes: When scientists first made contact with an isolated village of Yanomami hunter-gatherers in the remote mountains of the Amazon jungle of Venezuela in 2009, they marveled at the chance to study the health of people who had never been exposed to Western medicine or diets. But much to their surprise, these Yanomami’s gut bacteria have already evolved a diverse array of antibiotic-resistance genes, according to a new study, even though these mountain people had never ingested antibiotics or animals raised with drugs. The find suggests that microbes have long evolved the capability to fight toxins, including antibiotics, and that preventing drug resistance may be harder than scientists thought.

Submission + - FBI Accuses Researcher of Hacking Plane, Seizes Equipment (securityledger.com)

chicksdaddy writes: The Feds are listening and they really can't take a joke. That's the apparent moral of security researcher Chris Roberts' legal odyssey on Wednesday, which saw him escorted off a plane in Syracuse by two FBI agents and questioned for four hours over a humorous tweet Roberts posted about his ability to hack into the cabin control systems of the Boeing 737 he was flying.(https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Ftwitter.com%2FSidragon1%2Fstatus%2F588433855184375808) Roberts (aka @sidragon1), joked that he could "start playing with EICAS messages," a reference to the Engine Indicating and Crew Alerting System (http://en.wikipedia.org/wiki/Engine-indicating_and_crew-alerting_system).

Roberts was traveling to Syracuse to give a presentation. He said local law enforcement and FBI agents boarded the plane on the tarmac and escorted him off. He was questioned for four hours, with officers alleging they had evidence he had tampered with in-flight systems on an earlier leg of his flight from Colorado to Chicago.

In an interview with The Security Ledger (https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fsecurityledger.com%2F2015%2F04%2Fhacker-on-a-plane-fbi-seizes-researchers-gear%2F), Roberts said the agents questioned him about his tweet and whether he tampered with the systems on the United flight -something he denies doing.

Roberts had been approached earlier by the Denver office of the FBI which warned him away from further research on airplanes. The FBI was also looking to approach airplane makers Boeing and Airbus and wanted him to rebuild a virtualized environment he built to test airplane vulnerabilities to verify what he was saying.

Roberts refused, and the FBI seized his encrypted laptop and storage devices and has yet to return them, he said. The agents said they wished to do a forensic analysis of his laptop. Roberts said he declined to provide that information and requested a warrant to search his equipment. As of Friday, Roberts said he has not received a warrant.

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 + - 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,’”

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.
