Blinded by sun? Let your steering wheel guide you

WORRIED that the sun in your eyes will impair your driving? For the first time, a vibrating steering wheel will tell drivers where to steer when undipped headlights or other visual impediments leave them temporarily blinded.

Eelke Folmer and Burkay Sucu at the University of Reno in Nevada, designed the steering wheel to help cut the accident toll caused by glare, especially in winter, when motorists are most likely to be dazzled by low sun and reflections from snow and ice.

Cars with vibrating seats can already warn drivers when another vehicle is approaching in their blind spot. But the team's design is the only one to help drivers steer using tactile cues. The system relies on car sensors like GPS and lane-keeping cameras to map the road ahead and work out where the vehicle is. When sensors detect the driver may be dazzled and drifting from their lane, the vibro-tactile system buzzes into action.

The vibrations are tuned to 275 hertz, the frequency that our skin is most sensitive to. And the cues are directional, so if a driver drifts left, the left side of the wheel will vibrate - a signal to steer right until it stops vibrating, just like a rumble strip. "It's fairly easy for the system to anticipate or sense glare conditions and activate itself," says Folmer. The system worked well in tests with 12 volunteers in a simulator, but the drivers' hands strayed from the left and right vibrators - so the devices may need to be more widely distributed around the wheel.

It's promising work, says Paul Newman, who is developing a driverless car at the University of Oxford. "Touch is an extraordinarily rich sensory pathway and is an ideal way to provide safety-improving hints. In this case, the hints are felt at the very place action is required - on the steering wheel itself," he says.

Migrant Workers' Centre urges flexibility in Change of Employer policy

SINGAPORE: The Migrant Workers' Centre has urged the government to be more flexible in allowing foreign workers to change employers.

The centre's Chairman Yeo Guat Kwang told Channel NewsAsia that he is working with the Manpower Ministry to try and amend the policy.

The Migrant Workers' Centre said last year it received about 1,500 complaints from foreign workers, mostly for salary arrears cases.

Workers helping the Manpower Ministry with investigations are given a special pass to stay in Singapore under the Temporary Job Scheme.

Under the scheme, workers serving as prosecution witnesses may be allowed to find temporary employment while their cases are being investigated.

Migrant workers groups want the Temporary Job Scheme to be expanded to allow workers to remain in Singapore beyond the completion of their cases.

Mr Yeo said workers who are waiting for their workplace injury compensation should also be allowed to stay.

This, he said, could lead the way for a new transitional employment system for foreign workers.

Mr Yeo said: "If you say the only way for the workers is to go back, for some cases, it's not fair because they've only been here for a few months. I think we should amend this to make it easier for workers who unfortunately fall victim to one of these disputes, will be able to find employment with another employer.

"To me, I think it's good for the employer to employ these workers who are already here, rather than to go to the source country, and do a fresh recruitment, and these are workers who have already been here, we know how good their skills are."

Mr Yeo explained that making the Change of Employers policy more flexible is also in line with the MWC's call to improve the quality of foreign workers.

"At the end of the day, for us to be able to enable them to change employer and get re-employed, definitely this is a person that must have the right skill to work here," said Mr Yeo.

In addition, the Humanitarian Organisation for Migration Economics believes the restrictions of the Change of Employer policy do not favour these workers.

The organisation's president Bridget Tan explained: "This is called the sponsorship system. A work permit holder is tied to the employer. The work permit holder if once he or she leaves the employer unless with the approval of the employer this work permit holder will have to go home, repatriated.

"They find it difficult to enforce their rights under work permit conditions because they are so afraid and often threatened. Going home for many migrant workers whether domestic workers or foreign workers is not a choice for them because most of them are in debt to agents back home, money lenders back home.

"And going back with nothing, with no hope and promise of another job and the chance to change employers, sometimes they allow themselves to be exploited."

Ms Tan added workers are not allowed to change the industry they work in.

She said: "For example, if you come in as a construction worker, you can only find a job as a construction worker even though you have qualification that can allow you to work for example, as a waiter but you cannot because you come in as a construction worker, you have to be a construction worker. There are restrictions."

President of the Association of Employment Agencies, K Jayaprema said employers have concerns with a more flexible policy.

Mr Jayaprema said: "When such transfers kick in, if the employees are not very responsible, the employer might be stranded without a workforce because employees do have a tendency to be working in one company, train themselves up there and when there's opportunities in another company with a little bit of better salary, they move."

Employers have to send their foreign workers back within seven days of the cancellation of their work permits or they could lose the S$5,000 security bond with the Manpower Ministry.

Advocacy groups for migrant workers argue a more flexible change of employer policy would create greater mobility for workers.

With this mobility, migrant workers will no longer be at the mercy of employers.

There will be more incentive for employers to retain these workers, and treat them fairly.

MPs are expected to raise questions on how the government can address the grievances of foreign workers at the next sitting of Parliament.

Despite setbacks, airlines and passengers still on board the Dreamliner

The Boeing 787 Dreamliner, which has suffered through many years of delays and mechanical issues, is now grounded around the world after a series of incidents including two on-board fires. But experts predict the plane will still be a hit with airlines and passengers when it is once again cleared for takeoff.

Daniel Terdiman/CNET)

Boeing's 787 Dreamliner has suffered through a series of high-profile delays and setbacks, culminating in this week's grounding by the U.S. government, but thanks to its cutting-edge technology, it's almost certain the plane will thrive in spite of the repeated body blows.

The Dreamliner -- the much-heralded, next-generation plane that Boeing designed to offer airlines big fuel efficiencies and access to new intercontinental routes -- had already stumbled through more than three years of delays including an onboard electrical fire before the U.S. Federal Aviation Administration grounded the entire U.S.-based fleet this week in the wake of new on-board fires. Other countries quickly followed suit.

But notwithstanding those problems, the Dreamliner is one blessed airplane, given that while airlines and passengers are certain to be wary of it going forward, few are likely to turn their backs on it for good.

The basic features that got so many people excited about the Dreamliner remain the same, even as the headlines about its fleet-wide grounding blare: Airlines have ordered more than 800 of the new airplane because its first-of-a-kind composite fuselage and new-style engines promise them 20 percent fuel savings, as well as a long-haul range capable of opening up routes never before possible -- or at least, economical -- in a non-stop flight.

At the same time, passengers have been lining up to fly the plane because it's at the vanguard of both in-flight comfort and amenities, and recent excitement over the plane's arrival in new cities like San Jose, Calif. demonstrate just how enthusiastic some are to get on board.

A fire tied to lithium-ion batteries aboard an All Nippon Airways 787 earlier this week, coupled with a similar fire on a Japan Airlines 787 earlier this month, forced the FAA to take action. On January 16, the agency issued an airworthiness directive grounding the entire U.S.-based fleet of Dreamliners -- six United Airlines planes -- until the aircraft can be deemed safe. The two fires followed other recent mishaps on a number of Dreamliners including oil and fuel leaks, a cracked windshield, and false warnings from an electrical panel. "Before further flight," the FAA said in a statement, "operators of U.S.-registered, Boeing 787 aircraft must demonstrate to the Federal Aviation Administration (FAA) that the batteries are safe."

But while Boeing is certainly reeling from the latest setbacks to the $32 billion Dreamliner program, the aviation giant should be able to put these latest episodes behind it and resume delivering the planes before too long, several experts told CNET.

"They'll work this out," said Bob Mann, president of RW Mann, an aviation industry analysis firm. "It's a black eye. It's not a knock-out blow."

To Mann, the likelihood of the Dreamliner program's future success boils down to the fact that the plane features "so much breakthrough innovation" as well as the reality that carriers around the world have made tremendous financial investments in the 787, not to mention that many have based their future business plans on being able to fly the kinds of routes that the plane makes possible for the first time. Plus, having planned for those new routes and fuel costs, they have nowhere to turn: Boeing's chief competitor, Airbus, doesn't have a plane in the works that can match the Dreamliner on these key features.

Though composite materials have been used in some planes for awhile, the Dreamliner is the first to feature a fully-composite fuselage. That makes the plane lighter, making it more fuel efficient, but it also helps make the passenger experience better, according to Mann.

That's because the composite fuselage is stronger than that on other planes, allowing the cabin to be more pressurized. The upshot, explained Mann, is that Dreamliner flights are pressurized to mimic being at an altitude of about 6,000 feet, a much more comfortable environment than on other planes, which are usually pressurized to about a 9,000- or 10,000-foot altitude. And the plane is also designed to have a much more comfortable level of relative humidity, Mann said, because the composite fuselage doesn't need to be kept entirely dry to avoid corrosion.

At the same time, the Dreamliner's fuel efficiency is also driven by the Dreamliner's "no bleed" engines. Boeing claims that "all of the high-speed air produced by the engines goes to thrust [while] pneumatic systems that divert high-speed air from the engines rob conventional airplanes of some thrust and increase the engine's fuel consumption."

For now, no one knows exactly what the root cause of the recent fires is, beyond being tied to the lithium-ion batteries used on the plane. Japanese officials have argued that the battery was operating above its designed voltage limits, according to CBSNews.com.

The 787 relies more than any other modern airliner on electrical signals to help power nearly everything the plane does. It's also the first Boeing plane to use rechargeable lithium-ion batteries for its main electrical system. Such batteries are prone to overheating and have additional safeguards installed that are meant to control the problem and prevent fires.

GS Yuasa Corp., the maker of the lithium-ion batteries used in the 787s, said Thursday it was helping with the investigation but that the cause of the problem was unclear. It said the problem could be the battery, the power source or the electronics system.

And, of course, lithium-ion batteries have been blamed in fires in other products, like Chevrolet's Volt.

The prospect that the Dreamliner's battery system is fundamentally flawed, is, of course, a major concern for Boeing. But no one has yet definitely pinned the problems on the batteries. And to Chris Sloan, an aviation writer and enthusiast who runs Airchive.com, there's nothing particularly unique about the Dreamliner getting off to such a rocky beginning.

Many planes, Sloan argued, have had rough beginnings. Among them are the Lockheed Electra, which had three crashes in its first year; the McDonnell Douglas DC-10, which had a wide range of problems and was grounded following a massive crash in 1979; and the De Havilland Comet, which suffered through a series of stress fractures and crashes. In each case, Sloan said, airlines and passengers returned when the planes were once again cleared for flight. One significant difference between those planes and the Dreamliner is that no 787 has crashed, and no one has died aboard the plane.

Ultimately, said Imperial Capital aviation analyst Ken Herbert, Boeing is likely to be able to count on airlines and passengers continuing to support the Dreamliner because of all the plane's advantages, and particularly because so many airlines have invested so much in the aircraft. "I haven't heard any long term wavering on their desire to take delivery of the plane," Herbert said. "Airlines have planned on this [for years], and for them to change right now, if they're expecting one, it's not an easy switch to make."

To be sure, Boeing has a huge deal riding on the outcome of the investigations being done by the FAA and the U.S. National Transportation Safety Board. If the final determination is that the batteries are incompatible with the plane for one reason or another, it could be a major setback costing Boeing months and significant amounts of money. But short of that worst-case scenario, once the federal agencies sign off on the plane's airworthiness, Herbert has little doubt that the Dreamliner will once again be a favorite of the world's airlines and many aviation enthusiasts.

"I'm not expecting any public pushback or concern about flying on these planes," Herbert said. "Boeing has a lot at stake on her now, and the next few weeks are pretty important from a timing standpoint, and a public perception standpoint, and safety and reliability standpoint. They've got to be really careful that they don't do anything else to jeopardize (the public's) interest in getting on one of these things."

But will passengers come back? Herbert thinks so. "Generally, people still regard the industry as very safe, and they've got a lot of confidence in, [which is] rightfully well-deserved, the improvements Boeing and Airbus have made in their aircraft. Unless there's something else, people will move on quickly."

Attack at Algeria Gas Plant Heralds New Risks for Energy Development

The siege by Islamic militants at a remote Sahara desert natural gas plant in Algeria this week signaled heightened dangers in the region for international oil companies, at a time when they have been expanding operations in Africa as one of the world's last energy frontiers. (See related story: "Pictures: Four New Offshore Drilling Frontiers.")

As BP, Norway's Statoil, Italy's Eni, and other companies evacuated personnel from Algeria, it was not immediately clear how widely the peril would spread in the wake of the hostage-taking at the sprawling In Amenas gas complex near the Libyan border.

Map by National Geographic

Algeria, the fourth-largest crude oil producer on the continent and a major exporter of natural gas and refined fuels, may not have been viewed as the most hospitable climate for foreign energy companies, but that was due to unfavorable financial terms, bureaucracy, and corruption. The energy facilities themselves appeared to be safe, with multiple layers of security provided both by the companies and by government forces, several experts said. (See related photos: "Oil States: Are They Stable? Why It Matters.")

"It is particularly striking not only because it hasn't happened before, but because it happened in Algeria, one of the stronger states in the region," says Hanan Amin-Salem, a senior manager at the industry consulting firm PFC Energy, who specializes in country risk. She noted that in the long civil war that gripped the country throughout the 1990s, there had never been an attack on Algeria's energy complex. But now, hazard has spread from weak surrounding states, as the assault on In Amenas was carried out in an apparent retaliation for a move by French forces against the Islamists who had taken over Timbuktu and other towns in neighboring Mali. (See related story: "Timbuktu Falls.")

"What you're really seeing is an intensification of the fundamental problem of weak states, and empowerment of heavily armed groups that are really well motivated and want to pursue a set of aims," said Amin-Salem. In PFC Energy's view, she says, risk has increased in Mauritania, Chad, and Niger—indeed, throughout Sahel, the belt that bisects North Africa, separating the Sahara in the north from the tropical forests further south.

On Thursday, the London-based corporate consulting firm Exclusive Analysis, which was recently acquired by the global consultancy IHS, sent an alert to clients warning that oil and gas facilities near the Libyan and Mauritanian borders and in Mauritania's Hodh Ech Chargui province were at "high risk" of attack by jihadis.

"A Hot Place to Drill"

The attack at In Amenas comes at a time of unprecedented growth for the oil industry in Africa. (See related gallery: "Pictures: The Year's Most Overlooked Energy Stories.") Forecasters expect that oil output throughout Africa will double by 2025, says Amy Myers Jaffe, executive director of the energy and sustainability program at the University of California, Davis, who has counted 20 rounds of bidding for new exploration at sites in Africa's six largest oil-producing states.

Oil and natural gas are a large part of the Algerian economy, accounting for 60 percent of government budget revenues, more than a third of GDP and more than 97 percent of its export earnings. But the nation's resources are seen as largely undeveloped, and Algeria has tried to attract new investment. Over the past year, the government has sought to reform the law to boost foreign companies' interests in their investments, although those efforts have foundered.

Technology has been one of the factors driving the opening up of Africa to deeper energy exploration. Offshore and deepwater drilling success in the Gulf of Mexico and Brazil led to prospecting now under way offshore in Ghana, Mozambique, and elsewhere. (See related story: "New Oil—And a Huge Challenge—for Ghana.") Jaffe says the Houston-based company Anadarko Petroleum has sought to transfer its success in "subsalt seismic" exploration technology, surveying reserves hidden beneath the hard salt layer at the bottom of the sea, to the equally challenging seismic exploration beneath the sands of the Sahara in Algeria, where it now has three oil and gas operations.

Africa also is seen as one of the few remaining oil-rich regions of the world where foreign oil companies can obtain production-sharing agreements with governments, contracts that allow them a share of the revenue from the barrels they produce, instead of more limited service contracts for work performed.

"You now have the technology to tap the resources more effectively, and the fiscal terms are going to be more attractive than elsewhere—you put these things together and it's been a hot place to drill," says Jaffe, who doesn't see the energy industry's interest in Africa waning, despite the increased terrorism risk. "What I think will happen in some of these countries is that the companies are going to reveal new securities systems and procedures they have to keep workers safe," she says. "I don't think they will abandon these countries."

Te'o Denies Involvement in Girlfriend Hoax

Notre Dame star linebacker Manti Te'o told ESPN that he "never, not ever" was involved in creating the hoax that had him touting what turned out to be a fictional girlfriend, "Lennay Kekua."

"When they hear the facts, they'll know," Te'o told ESPN's Jeremy Schaap in his first interview since the story broke. "They'll know that there is no way that I could be a part of this."

"I wasn't faking it," he said during a 2 1/2-hour interview, according to ESPN.com.

Te'o said he only learned for sure this week that he had been duped. On Wednesday, he received a Twitter message, allegedly from a man named Ronaiah Tuiasosopo, apologizing for the hoax, Te'o told Schaap.

The sports website Deadspin, which first revealed the hoax this week, has reported that Tuiasosopo, a 22-year-old of Samoan descent who lives in Antelope Valley, Calif., asked a woman he knew for her photo and that photo became the face of Kekua's Twitter account.

Te'o told Schaap that Tuiasosopo was represented to him as Kekua's cousin.

"I hope he learns," Te'o said of Tuiasosopo, according to coverage of the interview on ESPN.com. "I hope he understands what he's done. I don't wish an ill thing to somebody. I just hope he learns. I think embarrassment is big enough."

Te'o admitted to a few mistakes in his own conduct, including telling his father he met Kekua in Hawaii even though his attempt to meet her actually failed. Later retellings of that tale led to inconsistencies in media reports, Te'o said, adding that he never actually met Kekua in person.

Te'o added that he feared people would think it was crazy for him to be involved with someone that he never met, so, "I kind of tailored my stories to have people think that, yeah, he met her before she passed away."

The relationship got started on Facebook during his freshman year, Te'o said.

"My relationship with Lennay wasn't a four-year relationship," Te'o said, according to ESPN.com. "There were blocks and times and periods in which we would talk and then it would end."

He showed Schaap Facebook correspondence indicating that other people knew of Kekua -- though Te'o now believes they, too, were tricked.

The relationship became more intense, Te'o said, after he received a call that Kekua was in a coma following a car accident involving a drunk driver on April 28.

Soon, Te'o and Kekua became inseparable over the phone, he said, continuing their phone conversations through her recovery from the accident, and then during her alleged battle against leukemia.

Even so, Te'o never tried to visit Kekua at her hospital in California.

"It never really crossed my mind," he said, according to ESPN.com. "I don't know. I was in school."

But the communication between the two was intense. They even had ritual where they discussed scripture every day, Te'o said. His parents also participated via text message, and Te'o showed Schaap some of the texts.

On Sept. 12, a phone caller claiming to be Kekua's relative told Te'o that Kekua had died of leukemia, Te'o said. However, on Dec. 6, Te'o said he got a call allegedly from Kekua saying she was alive. He said he was utterly confused and did not know what to believe.

ESPN's 2 1/2-hour interview was conducted in Bradenton, Fla., with Te'o's lawyer present but without video cameras. Schaap said Te'o was composed, comfortable and in command, and that he said he didn't want to go on camera to keep the setting intimate and avoid a big production.

According to ABC News interviews and published reports, Te'o received phone calls, text messages and letters before every football game from his "girlfriend." He was in contact with her family, including a twin brother, a second brother, sister and parents. He called often to check in with them, just as he did with his own family. And "Kekua" kept in contact with Te'o's friends and family, and teammates spoke to her on the phone.

China working age population falls

BEIJING: China's working-age population declined for the first time in recent decades in 2012, the government said on Friday, detailing the extent of a demographic time bomb experts say is one of Beijing's biggest challenges.

China introduced its controversial one-child policy in the late 1970s to control population growth, but its people are now ageing, moving to the cities, and increasingly male, government statistics showed.

The world's biggest national population rose by 6.7 million in 2012 to 1.354 billion people, excluding Hong Kong, Macau and Taiwan, the National Bureau of Statistics said.

Almost 118 boys were born for every 100 girls.

The working-age population -- defined as those from 15 to 59 -- fell by 3.45 million to 937 million, adding to concerns about how the country will provide for the elderly, with 194 million people now 60 or over.

It was the first absolute drop in the working-age segment in "a considerable period of time", said National Bureau of Statistics director Ma Jiantang, adding that he expected it to "fall steadily at least through 2030".

China's wealth gap and population imbalances are major concerns for the ruling Communist Party, which places huge importance on preserving social stability to avoid any potential challenge to its grip on power.

An estimated 180,000 protests break out across China every year, many of them sparked by a wide range of social issues, including wage disputes and rural workers being denied residents' rights in cities.

But the government faces a "major dilemma" over how it confronts the problem of a rapidly ageing population, said analysts.

"For older generations, life is going to be very painful," Sun Wenguang, a retired academic from Shandong University in Jinan, told AFP.

"The cost of 24-hour care in Beijing is probably 7,000 RMB a month, and how will this be funded? The average manual worker in China earns about 2,000 RMB a month (US$300), of course they don't want to share their money out."

Liang Zhongtang, a researcher at the Shanghai Academy of Social Sciences, said the government was reluctant to confront the population imbalance because of the sensitivity of the family planning policy.

"Actually the structural decline of the country's labour resources started long ago," he told AFP.

Most of the labour force was aged between 20 and 45, he said, with the proportion of older workers within that range increasing rapidly. "This means it is very hard for them to change their jobs or find a new employer", decreasing labour flexibility.

The problems of ageing and labour shortages were "severe" in the countryside, he said, but added: "Even though rural areas' social and economic problems are serious, they do not make onto the radar of mainstream (policy makers).

"They just ignore the problems plaguing this social stratum."

As late as 1982, the proportion of the population aged 60 or over in China was just five per cent, but it now stands at 14.3 per cent.

China's urban population rose to 712 million in 2012, up 21 million and adding to the strains on public services, while the rural population fell 14 million to 642 million.

Average per capita income was 26,959 yuan (US$4,296) in the cities, compared to 7,917 yuan in the countryside, the statistics said.

What should Google do about Facebook Graph Search?

Mark Zuckerberg introduces Graph Search on Tuesday. Should Google worry?

(Credit:
James Martin/CNET)

When Facebook introduced its next-generation search product in Menlo Park, Calif., this week, the announcement was no doubt being watched closely in nearby Mountain View.

The data that Google engineers have craved for years -- rich portraits of connections between people, places, and things, all tied to real identities -- was suddenly searchable on Facebook. It's data Google is trying to replicate, using Google+ and other products, but there's no doubt that Facebook's billion-member network has given it the advantage. You can imagine the Google crew listening to Mark Zuckerberg describe the data that underpins Graph Search and wishing they could get their hands on it.

In fact, two of them did. Lars Rasmussen and Tom Stocky, who both worked on search products at Google, defected to Facebook and began working on a new kind of search product. In 2011 they started on what would be introduced Tuesday as Graph Search. From the get-go it was clear that searching your social network was materially different than searching the Web. Like the Web, it could provide answers (who's a good dentist?) and entertainment (show me photos of my friends in Paris). But social networks promise something more, the duo said in an interview this week at CNET headquarters: bringing you closer to friends by helping you share experiences.

Lars Rasmussen, a former Google employee, is leading Facebook's efforts in search.

James Martin/CNET)

It's an approach that differs sharply from that of Google, where the search team is interested in getting users the best possible answers, at lightning speed, regardless of who their friends are. The question is which approach is better -- and, should Facebook's take on search prove popular with users, what Google should do about it.

Even though they built it, Rasmussen and Stocky say they can only guess at what social search will mean for the masses.

"This all remains to be seen," said Rasmussen, who previously started the company that became Google Maps and later created the more divisive Google Wave. "We're also curious about this question. Obviously we think there is something here -- otherwise, we wouldn't have spent so much time on it."

The power of social
One day Rasmussen opened Facebook to see that his friend Zuckerberg was listening to a song, which appeared in his news feed. Rasmussen, curious, clicked the link so he could listen along in real time. That prompted an embarrassed message from Zuckerberg: This song is terrible, Zuckerbeg said. Sorry about that!

"That interaction was much more valuable than just listening to the song," Rasmussen said. "Watching terrible movies with your best friends can be better than watching an awesome movie alone. Watching awesome movies with your best friends is where we're trying to get to."

In other words, social search promises to bring us more than mere answers -- it can also bring us into conversation.

"There's a little bit more to it than just finding the best place to have a meal tonight," Rasmussen said. "Knowing which of your friends recommended it, or which of your friends liked it, will help you have a more social experience."

Google has also introduced ways of making recommendations more social. Apps you purchase in the Google Play store will be displayed, along with your Google+ profile, when a friend searches for them. The same goes for reviews of places on Google Local. And if your Google+ friends +1 Web links, those links will rise higher in search results for you. For most people, though, Facebook better reflects a person's actual friends and family members than Google's social products do. Even if a healthy chunk of your friends and family members are on Google+, they might be lumped in with brands, publications, celebrities, and other people the user follows but doesn't have a personal connection with.

In short, it's easy for an average user to grok why they might search Facebook for "plumbers my friends like." Thanks to the fact that Graph Search is embedded at the top of Facebook, and can interpret natural language queries, it's easy to use, too. Google's social recommendations, scattered across various products, look weak by comparison.

Hey, 1 billion, meet 30 trillion
But what if the value of social search is overstated? Google sees your friends as important to answering search queries -- that was the point of Search Plus Your World, introduced last year -- but they're only one signal.

What are the other signals? Well, for starters, there are the 30 trillion Web sites Google has indexed, across 230 million domains. There's the Knowledge Graph, its database of 570 million people, places, and things, which now has mapped more than 18 billion connections. Google is betting that for most questions, that enormous database will provide better answers than the random sample offered by the average Facebook user's 150 friends.

Google declined to comment for this story. But its philosophy on search is readily apparent. Google wants to answer your question no matter who you are -- and, unlike Facebook, no matter who you know. The fact that you would have to rely on your friends having visited a good Chinese restaurant to get a decent recommendation is a huge bug, in Google's mind. Sure, it will show you suggestions from friends if it has some to share. But Google wants to answer your question well even if it doesn't.

At its announcement, Facebook made much of the difference between Graph Search and "Web search," which returns not answers but links to other Web pages that hopefully do. The thing is, Google has been trying to move beyond "10 blue links" for years now -- the Knowledge Graph is only the latest effort to deliver answers on the search results page itself. Even Facebook isn't above the blue links -- thanks to its partnership with Bing, you can perform Web searches inside the social network.

The battle to come
It's important to note that several major categories of Google search are as yet unaffected by Facebook's entry into the space: video search, product search, flight search, and maps.

But Graph Search is still in beta. Rasmussen and Stocky said they both have "years" of work ahead of them. So far Graph Search is available only in English, to a select few beta testers. It can't search status updates or notes. The recommendation engine for things like plumbers appears to rely heavily on "likes," and how many people have ever liked their plumber on Facebook? 

Still, it's easy to imagine where Graph Search might lead. And even in beta, there's one search Facebook does better than anyone else: photos. Facebook is the world's largest storehouse of pictures, and Graph Search makes them searchable in a way that is not only functional but fun. It handles vanity searches ("photos of me"), creeper searches ("photos of friends of my friends who are single"), and searches designed for pure exploration: photos of Paris, photos of puppies, photos from 1980. It's a rabbit hole every bit as fun to fall down as Wikipedia -- or, more to the point, Google Images.

If Facebook builds the rest of Graph Search as well as it did the photo components, Google may actually have something to worry about. In the meantime Google will continue building its version of the "Star Trek" computer, one that answers questions perfectly no matter your social connections.

Opinion: Lance One of Many Tour de France Cheaters

Editor's note: England-based writer and photographer Roff Smith rides around 10,000 miles a year through the lanes of Sussex and Kent and writes a cycling blog at: www.my-bicycle-and-I.co.uk

And so, the television correspondent said to the former Tour de France champion, a man who had been lionised for years, feted as the greatest cyclist of his day, did you ever use drugs in the course of your career?

"Yes," came the reply. "Whenever it was necessary."

"And how often was that?" came the follow-up question.

"Almost all the time!"

This is not a leak of a transcript from Oprah Winfrey's much anticipated tell-all with disgraced cyclist Lance Armstrong, but instead was lifted from a decades-old interview with Fausto Coppi, the great Italian road cycling champion of the 1940s and 1950s.

To this day, though, Coppi is lauded as one of the gods of cycling, an icon of a distant and mythical golden age in the sport.

So is five-time Tour winner Jacques Anquetil (1957, 1961-64) who famously remarked that it was impossible "to ride the Tour on mineral water."

"You would have to be an imbecile or a crook to imagine that a professional cyclist who races for 235 days a year can hold the pace without stimulants," Anquetil said.

And then there's British cycling champion Tommy Simpson, who died of heart failure while trying to race up Mont Ventoux during the 1967 Tour de France, a victim of heat, stress, and a heady cocktail of amphetamines.

All are heroes today. If their performance-enhancing peccadillos are not forgotten, they have at least been glossed over in the popular imagination.

As the latest chapter of the sorry Lance Armstrong saga unfolds, it is worth looking at the history of cheating in the Tour de France to get a sense of perspective. This is not an attempt at rationalisation or justification for what Lance did. Far from it.

But the simple, unpalatable fact is that cheating, drugs, and dirty tricks have been part and parcel of the Tour de France nearly from its inception in 1903.

Cheating was so rife in the 1904 event that Henri Desgrange, the founder and organiser of the Tour, declared he would never run the race again. Not only was the overall winner, Maurice Garin, disqualified for taking the train over significant stretches of the course, but so were next three cyclists who placed, along with the winner of every single stage of the course.

Of the 27 cyclists who actually finished the 1904 race, 12 were disqualified and given bans ranging from one year to life. The race's eventual official winner, 19-year-old Henri Cornet, was not determined until four months after the event.

And so it went. Desgrange relented on his threat to scrub the Tour de France and the great race survived and prospered-as did the antics. Trains were hopped, taxis taken, nails scattered along the roads, partisan supporters enlisted to beat up rivals on late-night lonely stretches of the course, signposts tampered with, bicycles sabotaged, itching powder sprinkled in competitors' jerseys and shorts, food doctored, and inkwells smashed so riders yet to arrive couldn't sign the control documents to prove they'd taken the correct route.

And then of course there were the stimulants-brandy, strychnine, ether, whatever-anything to get a rider through the nightmarishly tough days and nights of racing along stages that were often over 200 miles long. In a way the race was tailor-made to encourage this sort of thing. Desgrange once famously said that his idea of a perfect Tour de France would be one that was so tough that only one rider finished.

Add to this the big prizes at a time when money was hard to come by, a Tour largely comprising young riders from impoverished backgrounds for whom bicycle racing was their one big chance to get ahead, and the passionate following cycling enjoyed, and you had the perfect recipe for a desperate, high stakes, win-at-all-costs mentality, especially given the generally tolerant views on alcohol and drugs in those days.

After World War II came the amphetamines. Devised to keep soldiers awake and aggressive through long hours of battle they were equally handy for bicycle racers competing in the world's longest and toughest race.

So what makes the Lance Armstrong story any different, his road to redemption any rougher? For one thing, none of the aforementioned riders were ever the point man for what the U.S. Anti-Doping Agency has described in a thousand-page report as the most sophisticated, cynical, and far-reaching doping program the world of sport has ever seen-one whose secrecy and efficiency was maintained by ruthlessness, bullying, fear, and intimidation.

Somewhere along the line, the casualness of cheating in the past evolved into an almost Frankenstein sort of science in which cyclists, aided by creepy doctors and trainers, were receiving blood transfusions in hotel rooms and tinkering around with their bodies at the molecular level many months before they ever lined up for a race.

To be sure, Armstrong didn't invent all of this, any more than he invented original sin-nor was he acting alone. But with his success, money, intelligence, influence, and cohort of thousand-dollar-an-hour lawyers-and the way he used all this to prop up the Lance brand and the Lance machine at any cost-he became the poster boy and lightning rod for all that went wrong with cycling, his high profile eclipsing even the heads of the Union Cycliste Internationale, the global cycling union, who richly deserve their share of the blame.

It is not his PED popping that is the hard-to-forgive part of the Lance story. Armstrong cheated better than his peers, that's all.

What I find troubling is the bullying and calculated destruction of anyone who got in his way, raised a question, or cast a doubt. By all accounts Armstrong was absolutely vicious, vindictive as hell. Former U.S. Postal team masseuse Emma O'Reilly found herself being described publicly as a "prostitute" and an "alcoholic," and had her life put through a legal grinder when she spoke out about Armstrong's use of PEDs.

Journalists were sued, intimidated, and blacklisted from events, press conferences, and interviews if they so much as questioned the Lance miracle or well-greased machine that kept winning Le Tour.

Armstrong left a lot of wreckage behind him.

If he is genuinely sorry, if he truly repents for his past "indiscretions," one would think his first act would be to try to find some way of not only seeking forgiveness from those whom he brutally put down, but to do something meaningful to repair the damage he did to their lives and livelihoods.

Armstrong Admits to Doping, 'One Big Lie'

Lance Armstrong, formerly cycling's most decorated champion and considered one of America's greatest athletes, confessed to cheating for at least a decade, admitting on Thursday that he owed all seven of his Tour de France titles and the millions of dollars in endorsements that followed to his use of illicit performance-enhancing drugs.

After years of denying that he had taken banned drugs and received oxygen-boosting blood transfusions, and attacking his teammates and competitors who attempted to expose him, Armstrong came clean with Oprah Winfrey in an exclusive interview, admitting to using banned substances for years.

"I view this situation as one big lie that I repeated a lot of times," he said. "I know the truth. The truth isn't what was out there. The truth isn't what I said.

"I'm a flawed character, as I well know," Armstrong added. "All the fault and all the blame here falls on me."

In October, the U.S. Anti-Doping Agency issued a report in which 11 former Armstrong teammates exposed the system with which they and Armstrong received drugs with the knowledge of their coaches and help of team physicians.

The U.S. Postal Service Cycling Team "ran the most sophisticated, professionalized and successful doping program that sport has ever seen," USADA said in its report.

As a result of USADA's findings, Armstrong was stripped of his Tour de France titles. Soon, longtime sponsors including Nike began to abandon him, too.

Armstrong said he was driven to cheat by a "ruthless desire to win."

He told Winfrey that his competition "cocktail" consisted of EPO, blood transfusions and testosterone, and that he had previously used cortisone. He would not, however, give Winfrey the details of when, where and with whom he doped during seven winning Tours de France between 1999 and 2005.

He said he stopped doping following his 2005 Tour de France victory and did not use banned substances when he placed third in 2009 and entered the tour again in 2010.

"It was a mythic perfect story and it wasn't true," Armstrong said of his fairytale story of overcoming testicular cancer to become the most celebrated cyclist in history.

Armstrong would not name other members of his team who doped, but admitted that as the team's captain he set an example. He admitted he was "a bully" but said there "there was a never a directive" from him that his teammates had to use banned substances.

"At the time it did not feel wrong?" Winfrey asked.

"No," Armstrong said. "Scary."

"Did you feel bad about it?" she asked again.

"No," he said.

Armstrong said he thought taking the drugs was similar to filling his tires with air and bottle with water. He never thought of his actions as cheating, but "leveling the playing field" in a sport rife with doping.

Life expectancy lower in US than other rich countries

WEALTHY it may be, but healthy it is not. The US population experiences poorer health at all stages of life than the populations of 16 other rich countries.

Despite leading the world in pioneering anti-smoking laws, cancer screening and controlling high blood pressure, the US trails its richer "peer" countries in almost all other measures of health and longevity, says a US National Research Council report published last week.

At 75 years, men in the US have the lowest life expectancy in the group, while women have a life expectancy of 81 years - higher only than Denmark.

In nine categories of ill health ranging from infant mortality rates to the prevalence of sexually transmitted disease, US citizens consistently came at or near the bottom of the table.

"I was stunned by how pervasive the disadvantages were across so many factors," says Steve Woolf of Virginia Commonwealth University in Richmond, who chaired the report panel.

Woolf and his colleagues say that the problem is less to do with faults in the US health system, and more to do with behaviours that put US citizens at greater risk. "They consume the most calories per person, have higher rates of drug abuse, are less likely to use seat belts, and are more likely to use firearms in acts of violence," says Woolf.

Floods swamp Indonesia capital, 19,000 homeless

JAKARTA: Floods which have made more than 19,000 people homeless and killed three brought parts of the Indonesian capital to a standstill Thursday, with even the president forced to roll up his trousers.

The waist-deep muddy waters paralysed much of the centre of Jakarta, home to 20 million people and already notorious for its chaotic traffic.

Drivers were stuck in snaking queues for hours in the morning and cyclists pushed bikes with only the handlebars and seats visible.

President Susilo Bambang Yudhoyono was pictured in the grounds of the presidential palace with his trousers rolled up to the knee, brown water lapping his calves and threatening to flood the shrubbery.

"Jakarta is flooded: hopefully there won't be too many victims," he told photographers, ordering military, police and disaster officials to ensure safety.

The monsoon floods had driven more than 19,000 people from their homes, according to Jakarta governor Joko Widodo.

National disaster management agency spokesman Sutopo Purwo Nugroho said the death toll rose to three when a 35-year old man was electrocuted on Thursday. A two-year old boy was swept away and a 46-year-old man was electrocuted earlier this week.

The waters started to recede in the afternoon but floods remained in some areas including the central business district, where luxury hotels and the French, German and British embassies were surrounded.

Motorists trying to avoid the deluge drove along pavements and central reservations, or headed the wrong way down one-way streets. In some areas children punted rafts along roads which looked more like canals.

"Jakarta today is a huge swimming pool. Everyone's playing in the rain, walking in the water and laughing. The downside is, I have no idea how to get home, I might have to walk back three hours," 32-year-old administrative officer Yohanna, who uses a single name, told AFP.

Authorities raised the flood alert to its highest level early Thursday, said disaster agency spokesman Nugroho, describing the city as "besieged".

"The situation could get worse in the coming days as the rain shows little sign of abating," he told AFP.

But as rescuers rushed to evacuate residents, welfare ministry spokesman Tito Setiawan said the situation was under control.

"We have sent out trucks and rafts to move victims whose homes were inundated to temporary shelters. We will also provide food, water and humanitarian aid," he said.

Indonesia is regularly afflicted by deadly floods and landslides during its wet season, which lasts around half the year, and many in the capital live beside rivers which periodically overflow.

AT&T eyes international expansion for growth

AT&T is interested in buying a European carrier for growth, according to the Wall Street Journal.

With the U.S. market about to get more competitive, AT&T is looking at markets in Europe where it can upgrade technology and roll out new services and pricing strategies, the Wall Street Journal said, citing unnamed sources. It reported that AT&T is studying potential acquisitions, and could strike a deal by the end of the year. In particular, AT&T is looking at the U.K., Germany, and the Netherlands.

While the U.S. carriers have largely remained insular, many of the largest carriers overseas, such as Vodafone and Telefonica, have assets in multiple countries. With growth starting to slow in the U.S., it's natural for AT&T to look abroad.

But a deal isn't without risks, and the markets that AT&T is looking at are already highly competitive in their own right. These aren't fast-growing emerging markets, but fairly mature ones with several competitors already in place. Those issues, as well as the weak European markets, have led to falling valuations and potentially attractive prices for many of these companies.

AT&T, of course, isn't a stranger to doing business with a major European player. The company two years ago attempted to acquire T-Mobile USA, a unit of Germany's Deutsche Telekom. That deal, of course, fell apart due to regulatory scrutiny, and the company has been focusing on smaller deals since then.

It's unclear how such a deal would interfere or compliment the company's large network upgrade plans. The company is spending an additional $14 billion to upgrade its wireless and wireline networks as it looks to new sources of growth in the U.S.

But AT&T is also looking at a market that will get more competitive in the coming months. Softbank is poised to come in and inject capital into Sprint, and its leadership has already warned that it would introduce new pricing schemes to shake up the market. Deutsche Telekom has re-committed itself to T-Mobile, which is planning to merge with MetroPCS and likewise promised to introduce new competitive plans.

AT&T does currently have an international presence in the form of a business arm that provides services to multinational corporations, but it doesn't yet serve consumers.

An AT&T representative declined to comment on the report.

6 Ways Climate Change Will Affect You

Photograph by AP Photo/Marcio Jose Sanchez

The planet keeps getting hotter, new data showed this week. Especially in America, where 2012 was the warmest year ever recorded, by far. Every few years, the U.S. federal government engages hundreds of experts to assess the impacts of climate change, now and in the future.

From agriculture (pictured) to infrastructure to how humans consume energy, the National Climate Assessment Development Advisory Committee spotlights how a warming world may bring widespread disruption.

Farmers will see declines in some crops, while others will reap increased yields.

Won't more atmospheric carbon mean longer growing seasons? Not quite. Over the next several decades, the yield of virtually every crop in California's fertile Central Valley, from corn to wheat to rice and cotton, will drop by up to 30 percent, researchers expect. (Read about "The Carbon Bathtub" in National Geographic magazine.)

Lackluster pollination, driven by declines in bees due partly to the changing climate, is one reason. Government scientists also expect the warmer climate to shorten the length of the frosting season necessary for many crops to grow in the spring.

Aside from yields, climate change will also affect food processing, storage, and transportation—industries that require an increasing amount of expensive water and energy as global demand rises—leading to higher food prices.

Notre Dame: Football Star Was 'Catfished' in Hoax

Notre Dame's athletic director and the star of its near-championship football team said the widely-reported death of the star's girlfriend from leukemia during the 2012 football season was apparently a hoax, and the player said he was duped by it as well.

Manti Te'o, who led the Fighting Irish to the BCS championship game this year and finished second for the Heisman Trophy, said in a statement today that he fell in love with a girl online last year who turned out not to be real.

The university's athletic director, Jack Swarbrick, said it has been investigating the "cruel hoax" since Te'o approached officials in late December to say he believed he had been tricked.

Private investigators hired by the university subsequently monitored online chatter by the alleged perpetrators, Swarbrick said, adding that he was shocked by the "casual cruelty" it revealed.

"They enjoyed the joke," Swarbrick said, comparing the ruse to the popular film "Catfish," in which filmmakers revealed a person at the other end of an online relationship was not who they said they were.

"While we still don't know all of the dimensions of this ... there are certain things that I feel confident we do know," Swarbrick said. "The first is that this was a very elaborate, very sophisticated hoax, perpetrated for reasons we don't understand."

Te'o said during the season that his girlfriend, Lennay Kekua, died of leukemia in September on the same day Te'o's grandmother died, triggering an outpouring of support for Te'o at Notre Dame and in the media.

"While my grandma passed away and you take, you know, the love of my life [Kekua]. The last thing she said to me was, 'I love you,'" Te'o said at the time, noting that he had talked to Kekua on the phone and by text message until her death.

Now, responding to a story first reported by the sports website Deadspin, Te'o has acknowledged that Kekua never existed. The website reported today that there were no records of a woman named Lennay Kekua anywhere.

Te'o denied that he was in on the hoax.

"This is incredibly embarrassing to talk about, but over an extended period of time, I developed an emotional relationship with a woman I met online," Te'o said in a statement released this afternoon. "We maintained what I thought to be an authentic relationship by communicating frequently online and on the phone, and I grew to care deeply about her."

Swarbrick said he expected Te'o to give his version of events at a public event soon, perhaps Thursday, and that he believed Te'o's representatives were planning to disclose the truth next week until today's story broke.

Deadspin reported that the image attached to Kekua's social media profiles, through which the pair interacted, was of another woman who has said she did not even know Te'o or know that her picture was being used. The website reported that it traced the profiles to a California man who is an acquaintance of Te'o and of the woman whose photo was stolen.

"To realize that I was the victim of what was apparently someone's sick joke and constant lies was, and is, painful and humiliating," Te'o said.

NASA rover ready to drill into Martian rock

Victoria Jaggard, physical sciences news editor

(Image: NASA/JPL-Caltech/MSSS)

NASA's Curiosity rover is about to tap the rocky veins of Mars, which might yield clues to the Red Planet's watery past.

Exploring a region not far from where it landed on 6 August, the Curiosity rover has found rocks shot through with veins of light-coloured minerals. Chemical analysis from one of the rover's remote-sensing cameras shows that the veins are hydrated calcium sulphates, possibly gypsum. They probably formed when water flowed through fractures in the bedrock and left dissolved material behind behind.

The find takes NASA's mantra "follow the water" to a whole new level.

"The exciting thing about precipitated minerals is that we know something dissolved rock somewhere else on the planet and ions got transported along by a fluid," said project scientist John Grotzinger during a teleconference yesterday. Studying the mineral-laced rocks can give clues to where the water came from and to environmental conditions when the veins formed.

The team will use the rover's drill for the first time on a veined outcrop named John Klein, an homage to a former project worker who died in 2011. The drill can bite about 5 centimetres into Martian rock, collect pulverised samples and deliver material to other onboard instruments for analysis.

"What we are hoping to do is get a sense of the mineralogy - how many aqueous mineral phases are present, the isotope ratios, and even a chance to look for organics," Grotzinger said.

Although initially thought too soft to preserve fossils, previous work showed that gypsum on Earth can hold traces of ancient carbon-based life.

Elsewhere at the site - a shallow depression dubbed Yellowknife Bay - the rover has spotted rocks studded with rounded features called spherules, which also tell of fluids at work.

"We are feeling confident these are sedimentary concretions [rocks formed as sediments washed from afar become cemented together]," Grotzinger said. "Put that together with the veins, and basically these rocks were saturated with water."

Another outcrop at the site shows a texture called cross-bedding, which resembles stacked layers of rock. These features on Earth are associated with water pushing small dunes of sediments along a stream bed. "There's a real trend that's emerging here on our tour," Grotzinger said.

The team won't be ready to drill for a few weeks yet, as they continue to take samples with other instruments and then drive the rover to the John Klein outcrop.

"It takes a fairly extended period of time because drilling is the most significant engineering thing we've done since landing," said rover project manager Richard Cook. Team members have also been examining and recording the great diversity of rock types at Yellowknife Bay, some of which may also become targets for drilling.

"It's safe to say scientists have been led into the candy store," Cook said. "I'm really excited about the next few weeks."

Tennis: Djokovic dazzles in straight-sets win over Harrison

MELBOURNE: Novak Djokovic was in the zone with a dazzling demolition of Ryan Harrison as he stormed into the third round of the Australian Open on Wednesday.

The world number one was in irresistible form, outclassing the young American 6-1, 6-2, 6-3 in just one hour 31 minutes of high-class tennis on Rod Laver Arena.

Djokovic, a three-time winner and going for three straight Australian titles, will next play Czech journeyman Radek Stepanek in the last 32.

The Serb said it was one of the best matches he has played in the early rounds at a Grand Slam.

"I've played many matches in Grand Slams in my career, so it's tough to compare which one is the best I would take under the circumstances," he said.

"I tried to focus on the start and I knew that he had nothing to lose and would come out with his big serves, but I managed to make some very important early breaks at the start of the match.

"I was a set up after 20 minutes and it was a mental advantage, I felt much more comfortable on the court.

"This was definitely a better performance than the first round.

"I managed to play in a very high level already in the second round of a Grand Slam, which is very encouraging for next challenge."

Djokovic jumped out of the blocks and won 12 of the first 13 points to put the young American on the back foot and down an early service break.

He broke Harrison again in the sixth game and wrapped up the opening set in just 20 minutes.

The Serb top seed carried on where he left off breaking the American's opening service to win seven of the first eight games.

Djokovic broke Harrison's serve for a fourth time to carry on the blitz and raced to a two sets to love lead via three set points in 30 minutes.

Harrison was broken again in the opening game of the final set as Djokovic closed in on victory.

But the young American refused to give in and held three service games under pressure, to the appreciation of the centre court crowd.

Djokovic again put Harrison's service under pressure and took out the match on his second match point.

"He played really well," Harrison said. "Kind of getting broke in that first service game, giving a guy that's that good a little bit of a lead and letting him front-run is just not the ideal way to start."

Prosecutor in Aaron Swartz 'hacking' case comes under fire

Carmen Ortiz, U.S. Attorney for Massachusetts

(Credit:
U.S. Department of Justice)

A politically ambitious Justice Department official who oversaw the criminal case against Aaron Swartz has come under fire for alleged prosecutorial abuses that led the 26-year-old online activist to take his own life.

Carmen Ortiz, 57, the U.S. attorney for Massachusetts who was selected by President Obama, compared the online activist -- accused of downloading a large number of academic papers -- to a common criminal in a 2011 press release. "Stealing is stealing whether you use a computer command or a crowbar," Ortiz said at the time. Last fall, her office slapped Swartz with 10 additional charges that carried a maximum penalty of 50 years in prison.

"He was killed by the government," Swartz's father, Robert, said at his son's funeral in Highland Park, Ill., today, according to a report in the Chicago Sun Times.

Last Wednesday, less than three months before the criminal trial was set to begin, Ortiz's office formally rejected a deal that would have kept Swartz out of prison. Two days later, Swartz killed himself.

"He was being made into a highly visible lesson," says Harvey Silverglate, a Cambridge, Mass., attorney who first met Swartz in 2001 and spoke with him after his arrest. "He was enhancing the careers of a group of career prosecutors and a very ambitious -- politically-ambitious -- U.S. attorney who loves to have her name in lights."

Ortiz' spokeswoman did not respond to questions from CNET today. The spokeswoman, Christina Sterling, had said earlier this week: "We want to respect the privacy of the family and do not feel it is appropriate to comment on the case at this time."

Replies Silverglate, the defense attorney and author of the book "Three Felonies a Day:" "It nearly made me puke. Out of deference to the family they weren't going to respond to the charges? It wasn't 'out of deference to the family.' It was out of deference to their careers."

Swartz was accused of 13 felony counts relating to connecting a computer to MIT's network without authorization and retrieving over four million academic journal articles from the JSTOR database (he was allowed to access JSTOR, but not to perform a bulk download). The advocacy group Demand Progress, which Swartz had helped to create and which helped to defeat the Stop Online Piracy Act a year ago, likened it to "trying to put someone in jail for allegedly checking too many books out of the library." (Swartz also sold a company he founded called Infogami to Reddit and was one of the co-creators of the RSS standard for syndicating content.)

If Swartz had stolen a $100 hard drive with the JSTOR articles, it would have been a misdemeanor offense that would have yielded probation or community service. But the sweeping nature of federal computer crime laws allowed Ortiz and Assistant U.S. Attorney Stephen Heymann, who wanted a high-profile computer crime conviction, to pursue felony charges. Heymann threatened the diminutive free culture activist with over 30 years in prison as recently as last week.

The Boston U.S. Attorney's office was looking for "some juicy looking computer crime cases and Aaron's case, sadly for Aaron, fit the bill," Elliot Peters, Swartz's attorney at the Keker & Van Nest law firm, told the Huffington Post. Heymann, Peters says, thought the Swartz case "was going to receive press and he was going to be a tough guy and read his name in the newspaper."

Heymann was also the Boston office's point person in a second investigation that spurred another young hacker to kill himself. In 2008, 24-year-old Jonathan James committed suicide after being named a suspect in a federal cybercrime investigation. His suicide note said: "I have no faith in the 'justice' system. Perhaps my actions today, and this letter, will send a stronger message to the public."

"The charges were ridiculous and trumped-up"

Ortiz has now found herself in an unusual -- and uncomfortable -- position: as the target of an investigation instead of the initiator of one.

An online petition asking President Obama to remove her from office has garnered 35,000 signatures. The threshold at the time for triggering an official White House response, which has not yet happened, was 25,000. (A separate petition asking for the removal of prosecutor Stephen Heymann has attracted only 4,000 signatures so far.)

House Oversight Committee Chairman Darrell Issa, a California Republican, said he has launched an investigation into Ortiz's prosecution of Swartz. It's a bipartisan sentiment: Rep. Jared Polis, a Colorado Democrat and former Internet entrepreneur, told the Hill that: "The charges were ridiculous and trumped-up. It's absurd that he was made a scapegoat."

Rep. Zoe Lofgren, a Democrat whose district includes the heart of Silicon Valley, published draft legislation today (PDF) called "Aaron's Law" that would no longer make it a crime to violate terms of service agreements.

Ortiz had been a rising star in the Democratic Party: a law-and-order Hispanic prosecutor who had won high-profile convictions including Salvatore DiMasi, the former Massachusetts House speaker. The Boston Globe named her "Bostonian of the Year" in 2011 and reported last month that Ortiz was a potential gubernatorial candidate.

Swartz's friends and family have, in the days since his death, argued that Ortiz, Heymann, and assistant U.S. attorney Scott Garland employed tactics should have been reserved for serious criminals, not an activist who merely downloaded more articles than JSTOR would have preferred. A Swartz family statement posted at RememberAaronSW.com says: "The U.S. attorney's office pursued an exceptionally harsh array of charges, carrying potentially over 30 years in prison, to punish an alleged crime that had no victims."

Larry Lessig, the Harvard law professor who spoke at Swartz's funeral today along with Web inventor Tim Berners-Lee, said in a blog post that even though Swartz had no intention of profiting from any downloaded journal articles, "our government continued to push as if it had caught the 9/11 terrorists red-handed."

Alex Stamos, who the defense had planned to call as an expert witness on computer intrusion, said: "I know a criminal hack when I see it, and Aaron's downloading of journal articles from an unlocked closet is not an offense worth 35 years in jail." Law professor Tim Wu added that Ortiz's "legal authority to take down Swartz was shaky" after a federal appeals court ruling last year.

It's true that Swartz would not have faced 50 years in prison; that was, after all, the maximum sentence for his supposed felonies, not the minimum one. But Ortiz and her staff were intent on requiring that he plead guilty to multiple felonies and serve significant time behind bars.

Jennifer Granick, director of civil liberties at Stanford University's Center for Internet and Society and former criminal defense attorney, elaborated on why Swartz was so reluctant to plead guilty:

There was great practical risk to Aaron from pleading to any felony. Felons have trouble getting jobs, aren't allowed to vote (though that right may be restored) and cannot own firearms (though Aaron wasn't the type for that, anyway). More particularly, the court is not constrained to sentence as the government suggests. Rather, the probation department drafts an advisory sentencing report recommending a sentence based on the guidelines. The judge tends to rely heavily on that "neutral" report in sentencing... If he plead guilty to a felony, he could have been sentenced to as many as 5 years, despite the government's agreement not to argue for more. Each additional conviction would increase the cap by 5 years, though the guidelines calculation would remain the same. No wonder he didn't want to plead to 13 felonies. Also, Aaron would have had to swear under oath that he committed a crime, something he did not actually believe.

JSTOR has said since 2011 that it had no interest in pursuing criminal charges, and added last weekend that it "regretted" having been drawn into "this sad event." MIT, which reportedly did encourage Ortiz to pursue the case, is now conducting an internal investigation.

Last Wednesday, two days before Swartz took his life, JSTOR said it was making its archives of more than 1,200 different academic journals free for the public to read.

The first drill sample ever collected on Mars will come from a rockbed shot through with unexpected veins of what appears to be the mineral gypsum.

Delighted members of the Curiosity science team announced Tuesday that the rover was now in a virtual "candy store" of scientific targets—the lowest point of Gale crater, called Yellowknife Bay, is filled with many different materials that could have been created only in the presence of water. (Related: "Mars Has 'Oceans' of Water Inside?")

Project scientist John Grotzinger, of the California Institute of Technology in Pasadena, said during a press conference that the drill area has turned out "to be jackpot unit. Every place we drive exposes fractures and vein fills."

Mission scientists initially decided to visit the depression, a third of a mile from Curiosity's landing site, on a brief detour before heading to the large mountain at the middle of Gale Crater. But because of the richness of their recent finds, Grotzinger said it may be some months before they begin their trek to Mount Sharp.

The drilling, expected to start this month, will dig five holes about two inches (five centimeters) into bedrock the size of a throw rug and then feed the powder created to the rover's two chemistry labs for analysis.

The drill is the most complex device on the rover and is the last instrument to be used. Project Manager Richard Cook, of NASA's Jet Propulsion Laboratory, said that operating it posed the biggest mechanical challenge since Curiosity's high-drama landing. (Watch video of Curiosity's "Seven Minutes of Terror.")

A Watery Past?

That now-desiccated Mars once had a significant amount of surface water is now generally accepted, but every new discovery of when and where water was present is considered highly significant. The presence of surface water in its many possible forms—as a running stream, as a still lake, as ground water soaked into the Martian soil—all add to an increased possibility that the planet was once habitable. (Watch a video about searching for life on Mars.)

And each piece of evidence supporting the presence of water brings the Curiosity mission closer to its formal goal—which is to determine whether Mars was once capable of supporting life.

Curiosity scientists have already concluded that a briskly moving river or stream once flowed near the Gale landing site.

The discovery of the mineral-filled veins within Yellowknife Bay rock fractures adds to the picture because those minerals can be deposited only in watery, underground conditions.

The Curiosity team has also examined Yellowknife Bay for sedimentary rocks with the rover's Mars Hand Lens Imager (MAHLI).  Scientists have found sandstone with grains up to about the size of a peppercorn, including one shaped like a flower bud that appears to gleam. Other nearby rocks are siltstone, with grains finer than powdered sugar. These are quite different from the pebbles and conglomerate rocks found in the landing area, but all these rocks are evidence of a watery past. (Related: "A 2020 Rover Return to Mars?")

One of the primary reasons Curiosity scientists selected Gale crater as a landing site was because satellite images indicated that water-formed minerals were present near the base of Mount Sharp. Grotzinger said that the minerals' presence so close to the landing site, and some five miles from the mountain, is both a surprise and an opportunity.

The current site in Yellowknife Bay is so promising, Grotzinger said, that he would have been "thrilled" to find similar formations at the mission's prime destination at the base of Mount Sharp.  Now the mission can look forward to the surprises to come at the mountain base while already having struck gold.

NRA Ad Calls Obama 'Elitist Hypocrite'

As the White House prepares to unveil a sweeping plan aimed at curbing gun violence, the National Rifle Association has launched a preemptive, personal attack on President Obama, calling him an “elitist hypocrite” who, the group claims, is putting American children at risk.

In 35-second video posted online Tuesday night, the NRA criticizes Obama for accepting armed Secret Service protection for his daughters, Sasha and Malia, at their private Washington, D.C., school while questioning the placement of similar security at other schools.

“Are the president’s kids more important than yours? Then why is he skeptical about putting armed security in our schools, when his kids are protected by armed guards at their school?” the narrator says.

“Mr. Obama demands the wealthy pay their fair share of taxes, but he’s just another elitist hypocrite when it comes to a fair share of security,” it continues. “Protection for their kids and gun-free zones for ours.”

The immediate family members of U.S. presidents – generally considered potential targets – have long received Secret Service protection.

The ad appeared on a new website for a NRA advocacy campaign – “NRA Stand and Fight” — that the gun-rights group appears poised to launch in response to Obama’s package of gun control proposals that will be announced today.

It’s unclear whether the video will air on TV or only on the web. The NRA did not respond to ABC News’ request for comment.  The domain for the website is registered to Ackerman McQueen, the NRA’s long-standing public relations firm.

The White House had no comment on the NRA ad.

In the wake of last month’s mass shooting at Sandy Hook Elementary School, the Obama administration has met with a cross-section of advocacy groups on all sides of the gun debate to formulate new policy proposals.

The NRA, which met with Vice President Joe Biden last week, has opposed any new legislative gun restrictions, including expanded background checks and limits on the sale of assault-style weapons, instead calling for armed guards at all American schools.

Obama publicly questioned that approach in an interview with “Meet the Press” earlier this month, saying, “I am skeptical that the only answer is putting more guns in schools. And I think the vast majority of the American people are skeptical that that somehow is going to solve our problem.”

Still, the White House has been considering a call for increased funding for police officers at public schools and the proposal could be part of a broader Obama gun policy package.

Fifty-five percent of Americans in the latest ABC News/Washington Post poll say they support adding armed guards at schools across the country.

“The issue is, are there some sensible steps that we can take to make sure that somebody like the individual in Newtown can’t walk into a school and gun down a bunch of children in a shockingly rapid fashion.  And surely, we can do something about that,” Obama said at a news conference on Monday.

“Responsible gun owners, people who have a gun for protection, for hunting, for sportsmanship, they don’t have anything to worry about,” he said.

Selling the appeal of statistics

In Naked Statistics economist Charles Wheelan aims to entice with dazzling data

STATISTICS lecturers have to come to terms with the fact that many students would rather not be there. Most signed up to study business or psychology, and doing strange things with numbers feels like an irksome side requirement of their primary pursuit.

Yet, as writer and public policy lecturer Charles Wheelan points out in Naked Statistics, the same students who complain that the subject is irrelevant are happy to spend their free time reading news stories that feature survey results or discussing sports statistics - basketball player LeBron James's points per game, or their favourite baseball pitcher's earned run average, for example. (As a warning, the book is deeply entrenched in US contexts. If you don't know much about baseball, Schlitz beer or even who LeBron James is - I had to look him up - you might find most of the examples alienating.)

Wheelan aims to link these two parts of his students' worlds by showing how statistics can be used to answer questions that are important and relevant to our lives. And he doesn't want to stop at the classroom door. Does he succeed? Sort of.

He has some good stories. To demonstrate randomisation in designing experiments, for example, he describes a study that investigated whether being prayed for by strangers would reduce complications after heart bypass surgery. (It didn't.) He also shows how important the wording of a question is to getting meaningful answers from polls: people in the US are considerably less likely to express support for the death penalty if also presented with the alternative of whole-life imprisonment without parole.

Yet Wheelan also experiments with made-up examples that, by his own admission, are utterly implausible. His story about a crash between two buses - one full of marathon runners and the other going to an international sausage festival - is memorable, but I wonder how relevant.

Though his style is innovative and often witty, most of the statistical topics he focuses on are pretty routine, and seem torn from the pages of a Statistics 101 syllabus: descriptive statistics, probability, sampling issues, inference, regression and the Central Limit Theorem, which explains why averages tend to follow the symmetric bell curve that makes up normal distribution. (This is, apparently, "the LeBron James of statistics".) And although he says he won't, he does get technical in a rather confusing way in the chapters on inference and regression, while some of his discussion of significance tests is problematic.

Still, there are things that you wouldn't find in an introductory statistics class. His final chapter, on "program evaluation", shows how you can use statistical ideas to make evidence-based decisions, such as whether to put more police officers on the street to deter crime. And he wraps up by applying statistics to five big questions, including how best to fight global poverty. These are interesting, engaging and useful.

In the end, Wheelan doesn't sell the marvellous world of statistics quite as well as he aims to. Yet he does make many interesting points, and often uses intriguing examples - I might even borrow a few for my own students.
