What Scientists Learned Mapping a Sunken Aircraft Carrier

SCIENTISTS HAVE SURVEYED a World War II-era aircraft carrier scuttled off the coast of San Francisco in 1951, advancing our understanding of how thoroughly we can explore the ocean floor while providing new knowledge about how ships fare after decades under water.

The 3-D sonar survey of the USS Independence was part of a two-year project by the National Oceanic and Atmospheric Administration to find and document hundreds of wrecks in the Gulf of the Farallones and learn more about the area’s rich maritime and biological history.

+ - Scientists close to solving the mystery of where dogs came from->

sciencehabit writes: For years researchers have argued over where and when dogs arose. Some say Europe, some say Asia. Some say 15,000 years ago. some say more than 30,000 years ago. Now an unprecedented collaboration of archaeologists and geneticists from around the world is attempting to solve the mystery once and for all. They're analyzing thousands of bones, employing new technologies, and trying to put aside years of bad blood and bruised egos. If the effort succeeds, the former competitors will uncover the history of man's oldest friend—and solve one of the greatest mysteries of domestication.

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

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 In a later tweet that was subsequently withdrawn, Musk then indicated that "the issue was stiction in the biprop throttle valve, resulting in control system phase lag."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.

+ - L.A. schools seeking refund over botched iPad plan->

Submitted by SternisheFan
SternisheFan writes: (Reuters) — The Los Angeles Unified School District is seeking a refund from Apple Inc (AAPL.O) over the district's bungled $1.3 billion effort to supply students with iPads, the Los Angeles Times reported on Wednesday.

The district's initiative, launched in 2013, to equip each of its roughly 650,000 students with an iPad or another computer device with curriculum from Pearson Plc (PSON.L), was the largest educational technology project of its kind in the United States.

The project soon ran into difficulties, however, and the technology rollout encountered a series of problems, including students bypassing a security firewall on the iPads, while an independent report found that the built-in curriculum was often incomplete.

The Los Angeles Times said the LAUSD's Board of Education in a closed-door meeting on Tuesday authorized its attorneys to consider potential legal action against Apple and Pearson.

"As you are aware, LAUSD is extremely dissatisfied with the work of Pearson," the district's general counsel, David Holmquist, said in a letter to Apple on Monday, according to the Times. "While Apple and Pearson promised a state-of-the-art technological solution [...] they have yet to deliver it."

Holmquist added that the district was severing ties with both companies for future services on the project, according to the Los Angeles Times.

+ - Chess grandmaster accused of using iPhone to cheat during international tourname->

Submitted by SternisheFan
SternisheFan writes: Gaioz Nigalidze’s rise through the ranks of professional chess began in 2007, the year the first iPhone was released. In hindsight, the timing might not be coincidental.

On Saturday, Nigalidze, the 25-year-old reigning Georgian champion, was competing in the 17th annual Dubai Open Chess Tournament when his opponent spotted something strange.

“Nigalidze would promptly reply to my moves and then literally run to the toilet,” Armenian grandmaster Tigran Petrosian said. “I noticed that he would always visit the same toilet partition, which was strange, since two other partitions weren’t occupied.”

Petrosian complained to the officials. After Nigalidze left the bathroom once more, officials inspected the interior and say they found an iPhone wrapped in toilet paper and hidden behind the toilet.

“When confronted, Nigalidze denied he owned the device,” according to the tournament’s Web site. “But officials opened the smart device and found it was logged into a social networking site under Nigalidze’s account. They also found his game being analyzed in one of the chess applications.”

Nigalidze was expelled from the tournament, which is still ongoing and features more than 70 grandmasters from 43 countries competing for a first-place prize of $12,000. The Georgian’s career is now under a microscope. His two national titles are under suspicion. And under recently tightened rules against cheating, he could be banned for up to 15 years.

But the scandal threatens to spread far beyond the gleaming white Dubai Chess & Culture Club, which is shaped like a giant rook. Nigalidze’s expulsion is a nightmare scenario for chess: proof positive that technologically enabled cheating, rumored about for more than a decade, is now pervasive. Thanks to smart phones, the game of kings is starting to look like the game of crooks.

+ - Prosecutors suspect man hacked lottery computers to score winning ticket->

Submitted by SternisheFan
SternisheFan writes: Prosecutors say they have evidence indicating the former head of computer security for a state lottery association tampered with lottery computers prior to him buying a ticket that won a $14.3 million jackpot, according to a media report.

Eddie Raymond Tipton, 51, may have inserted a thumbdrive into a highly locked-down computer that's supposed to generate the random numbers used to determine lottery winners, The Des Moines Register reported, citing court documents filed by prosecutors. At the time, Tipton was the information security director of the Multi-State Lottery Association, and he was later videotaped purchasing a Hot Lotto ticket that went on to fetch the winning $14.3 million payout.

In court documents filed last week, prosecutors said there is evidence to support the theory Tipton used his privileged position inside the lottery association to enter a locked room that housed the random number generating computers and infect them with software that allowed him to control the winning numbers. The room was enclosed in glass, could only be entered by two people at a time, and was monitored by a video camera. To prevent outside attacks, the computers aren't connected to the Internet. Prosecutors said Tipton entered the so-called draw room on November 20, 2010, ostensibly to change the time on the computers. The cameras on that date recorded only one second per minute rather than running continuously like normal.

"Four of the five individuals who have access to control the camera's settings will testify they did not change the cameras' recording instructions," prosecutors wrote. "The fifth person is defendant. It is a reasonable deduction to infer that defendant tampered with the camera equipment to have an opportunity to insert a thumbdrive into the RNG tower without detection."
