Amazon to open market in second-hand MP3s and e-books

A new market for second-hand digital downloads could let us hold virtual yard sales of our ever-growing piles of intangible possessions

WHY buy second-hand? For physical goods, the appeal is in the price – you don't mind the creases in a book or rust spots on a car if it's a bargain. Although digital objects never lose their good-as-new lustre, their very nature means there is still uncertainty about whether we actually own them in the first place, making it tricky to set up a second-hand market. Now an Amazon patent for a system to support reselling digital purchases could change that.

Amazon's move comes after last year's European Union ruling that software vendors cannot stop customers from reselling their products. But without technical support, the ruling has had no impact. In Amazon's system, customers will keep their digital purchases – such as e-books or music – in a personal data store in the cloud that only they can access, allowing them to stream or download the content.

This part is like any cloud-based digital locker except that the customer can resell previous purchases by passing the access rights to another person. Once the transaction is complete, the seller will lose access to the content. Any system for reselling an e-book, for example, would have to ensure that it is not duplicated in the transaction. That means deleting any copies the seller may have lying around on hard drives, e-book readers, and other cloud services, since that would violate copyright.

Amazon may be the biggest company to consider a second-hand market, but it is not the first. ReDigi, based in Boston, has been running a resale market for digital goods since 2011. After downloading an app, users can buy a song on ReDigi for as little as 49 cents that would costs 99 cents new on iTunes.

When users want to sell an item, they upload it to ReDigi's servers via a mechanism that ensures no copy is made during the transfer. Software checks that the seller does not retain a copy. Once transferred, the item can be bought and downloaded by another customer. ReDigi is set to launch in Europe in a few months.

Digital items on ReDigi are cheaper because they are one-offs. If your hard drive crashes and you lose your iTunes collection you can download it again. But you can only download an item from ReDigi once – there is no other copy. That is the trade-off that makes a second-hand digital market work: the risk justifies the price. The idea has ruffled a few feathers – last year EMI sued ReDigi for infringement of copyright. A judge denied the claim, but the case continues.

Used digital goods can also come with added charm. ReDigi tracks the history of the items traded so when you buy something, you can see who has owned it and when. ReDigi's second-hand marketplace has grown into a social network. According to ReDigi founder John Ossenmacher, customers like seeing who has previously listened to a song. "It's got soul like an old guitar," he says. "We've introduced this whole feeling of connectedness."

It could be good for business too if the original vendors, such as iTunes, were to support resale and take a cut of the resell price. Nevertheless, Amazon's move bucks the industry trend. Microsoft's new Xbox, for example, is expected not to work with second-hand games.

But the market could change rapidly now that Amazon's weight is behind this, says Ossenmacher. "The industry is waking up."

MPs, businesses hope Budget will address cost of living, labour crunch

SINGAPORE: Ahead of the delivery of Singapore's Budget on Monday, cost of living and labour crunch are among some issues MPs and businesses hope will be addressed.

Several MPs Channel NewsAsia spoke to said that a key concern especially amongst the sandwiched class is the cost of living in the country.

As for the elderly residents, they are concerned about healthcare costs, said the MPs.

On their part, businesses are worried about the manpower crunch and over the past month, there have been several calls to ease the tightening of the foreign worker inflow.

The government has been calling on companies to make concerted efforts to improve their productivity levels.

Zainudin Nordin, chairman of Government Parliamentary Committee (GPC) for Manpower, said: "When we look and talk about productivity, it sounds good. But how do we implement the productivity uplifting of our SMEs and companies? There needs to be a strong collaboration.

"When there is an intent on the part of the government to provide the resources in terms of consultancy and funds, there must also be a commitment and passion amongst the employers to see and understand that whenever they need to do more things, the first thing that must come to their mind is, 'how can I do more without employing more people?'. That is the direct question they have to ask themselves. Productivity is about doing more with lesser resources, that's the question.

"So, that should be the first question that comes to our mind, and when we need assistance from the government we should be able to come in and help in a much more concerted way.

"At the same time we also know the employees must also continue to ensure (they stay) relevant. So machinery, resources and employees must all be in tandem to do this. The partnership must be stronger."

Dr Lim Wee Kiak, chairman of GPC for Defence and Foreign Affairs, said: "We have received feedback as to the cost of childcare, cost of education and tuition, and these add a lot of stress to young parents. On top of that, they have to take care of their elderly parents. I think the key for that is the cost of healthcare.

"So within this Budget itself, I hope there will be some consideration for, especially the young and the old, and that will help the sandwiched class a lot."

Mr Baey Yam Keng, chairman of GPC for Culture, Community and Youth, said: "There has been some anticipation, because there has been a (budget) surplus. People know there is a surplus and people would look forward to investment in infrastructure. The gaps that we are seeing now in transport, housing, healthcare...people want to see their immediate frustrations being addressed...as well as the cost of living, these would be the key issues from residents.

"There is some apprehension over whether rentals will go up, if transport fares will go up.

"At the same time there are also residents operating their own businesses, the SMEs, who also have concerns about the manpower crunch, the cost of dong business and how they can continue to survive in this climate."

The Budget Statement will be delivered in Parliament by Deputy Prime Minister and Finance Minister Tharman Shanmugaratnam.

Channel NewsAsia will carry a special Budget programme from 3pm on Monday, together with Mr Tharman's speech live.

Budget 2013 will be tabled in Parliament against the backdrop of a 1.3 percent GDP growth for the entire 2012.

For 2013, the Ministry of Trade and Industry (MTI) has forecast an economic growth of one to three percent.

MTI also revealed on Friday that labour productivity had fallen by 2.6 percent in 2012, a reversal from the growth of 1.3 per cent from the previous year.

The ministry said productivity also dropped by 2.5 per cent in the fourth quarter, the fifth consecutive quarter of decline.

It said the fall was broad-based, with manufacturing, construction and services all experiencing negative growth.

The Facebook mistakes people make after a date

February can make people excitable.

A new year is barely old. Hope springs eternal. And then there's Valentine's Day to add a little piquancy to their emotional state.

Sometimes, though, lovers suffer from a certain lack of self-control. This can manifest itself on society's everyday manifest: Facebook.

I was moved, therefore, that someone had taken the time to list the major faux pas that occur when social contact accelerates beyond decent norms.

I am lovingly grateful to Ranker, which has taken it upon itself to reduce the rancor that might be caused by Facebooked overenthusiasm -- the site has listed behavior to avoid.

Apparently the worst thing you can do after meeting someone in whose charm and personality you might be interested is to immediately send them a Facebook friend request.

This might seem obvious to some.

You don't necessarily have any idea what the other person might really think of you. You know, inside their heads.

And, as Ranker wisely offers: "Now you've just given yourself something else to obsess over: 'Why hasn't my friend request been accepted? Why is it taking so long? Did they even see it?!'

And from one small click, a whole new series of sessions with your shrink is created.

It seems, though, that the human imagination has found many more ways of ruining the course of true love on Facebook.

People apparently pore over their new date's Facebook page, seeking secrets to their true friends, thoughts, and, who knows, other objects of affection.

Some devolve into what seems utterly psychotic behavior, such as liking old photos of their new potential paramour. Who does that? Twisted humans, that's who.

But Facebook offers so many more opportunities for self-destruction.

There's revealing too much in your status update. Sample: "I just went on the best date ever with Marie Dupree and her sexy knees."

More Technically Incorrect

Some people, though, go even further and attempt to insert themselves into comments on their love-object's Facebook page, should they already be Facebook friends. Sample: "You look so WONDERFUL when you're saluting the sun, Shoshanna. Can't wait until we do some saluting together!!"

No, it doesn't end there.

The Facebook gauche end up stalking every second of their new friend's Timeline. ("She dated a clown in 2008? Why would she DO that?")

Worse, there are apparently instances of enthusiasts who get so carried away that they start friending the families of their new objects of affection. ("Hi, Mrs. Aziel, you don't know me, but your daughter and I...." Oh, you finish the sentence.)

Facebook offers so many avenues of potential despair that there is only one way that you can use it to avoid complication, pain, sorrow, heartbreak, sleepless nights, and that bottomless feeling of lost opportunity: Don't go anywhere near it.

Top 10 Facebook Mistakes to Avoid After 1st Dates

Elderly Abandoned at World's Largest Religious Festival

Every 12 years, the northern Indian city of Allahabad plays host to a vast gathering of Hindu pilgrims called the Maha Kumbh Mela. This year, Allahabad is expected to host an estimated 80 million pilgrims between January and March. (See Kumbh Mela: Pictures From the Hindu Holy Festival)

People come to Allahabad to wash away their sins in the sacred River Ganges. For many it's the realization of their life's goal, and they emerge feeling joyful and rejuvenated. But there is also a darker side to the world's largest religious gathering, as some take advantage of the swirling crowds to abandon elderly relatives.

"They wait for this Maha Kumbh because many people are there so nobody will know," said one human rights activist who has helped people in this predicament and who wished to remain anonymous. "Old people have become useless, they don't want to look after them, so they leave them and go."

Anshu Malviya, an Allahabad-based social worker, confirmed that both men and women have been abandoned during the religious event, though it has happened more often to elderly widows. Numbers are hard to come by, since many people genuinely become separated from their groups in the crowd, and those who have been abandoned may not admit it. But Malviya estimates that dozens of people are deliberately abandoned during a Maha Kumbh Mela, at a very rough guess.

To a foreigner, it seems puzzling that these people are not capable of finding their own way home. Malviya smiles. "If you were Indian," he said, "you wouldn't be puzzled. Often they have never left their homes. They are not educated, they don't work. A lot of the time they don't even know which district their village is in."

Once the crowd disperses and the volunteer-run lost-and-found camps that provide temporary respite have packed away their tents, the abandoned elderly may have the option of entering a government-run shelter. Conditions are notoriously bad in these homes, however, and many prefer to remain on the streets, begging. Some gravitate to other holy cities such as Varanasi or Vrindavan where, if they're lucky, they are taken in by temples or charity-funded shelters.

In these cities, they join a much larger population, predominantly women, whose families no longer wish to support them, and who have been brought there because, in the Hindu religion, to die in these holy cities is to achieve moksha or Nirvana. Mohini Giri, a Delhi-based campaigner for women's rights and former chair of India's National Commission for Women, estimates that there are 10,000 such women in Varanasi and 16,000 in Vrindavan.

But even these women are just the tip of the iceberg, says economist Jean Drèze of the University of Allahabad, who has campaigned on social issues in India since 1979. "For one woman who has been explicitly parked in Vrindavan or Varanasi, there are a thousand or ten thousand who are living next door to their sons and are as good as abandoned, literally kept on a starvation diet," he said.

According to the Hindu ideal, a woman should be looked after until the end of her life by her male relatives—with responsibility for her shifting from her father to her husband to her son. But Martha Chen, a lecturer in public policy at Harvard University who published a study of widows in India in 2001, found that the reality was often very different.

Chen's survey of 562 widows of different ages revealed that about half of them were supporting themselves in households that did not include an adult male—either living alone, or with young children or other single women. Many of those who did live with their families reported harassment or even violence.

According to Drèze, the situation hasn't changed since Chen's study, despite the economic growth that has taken place in India, because widows remain vulnerable due to their lack of education and employment. In 2010, the World Bank reported that only 29 percent of the Indian workforce was female. Moreover, despite changes in the law designed to protect women's rights to property, in practice sons predominantly inherit from their parents—leaving women eternally dependent on men. In a country where 37 percent of the population still lives below the poverty line, elderly dependent relatives fall low on many people's lists of priorities.

This bleak picture is all too familiar to Devshran Singh, who oversees the Durga Kund old people's home in Varanasi. People don't pay toward the upkeep of their relatives, he said, and they rarely visit. In one case, a doctor brought an old woman to Durga Kund claiming she had been abandoned. After he had gone, the woman revealed that the doctor was her son. "In modern life," said Singh, "people don't have time for their elderly."

Drèze is currently campaigning for pensions for the elderly, including widows. Giri is working to make more women aware of their rights. And most experts agree that education, which is increasingly accessible to girls in India, will help improve women's plight. "Education is a big force of social change," said Drèze. "There's no doubt about that."

Las Vegas Strip Shooting Suspect ID'd

Las Vegas police identified a suspect today in a shooting on the strip that caused a Maserati to hit a taxi and burst into flames, killing three people.

Ammar Harris, 26, has been named a suspect in the Thursday skirmish that killed three people, including rapper Kenny Clutch.

The altercation between Harris and Clutch, 27, whose legal name was Kenneth Cherry Jr., is believed to have originated in the valet area of a Las Vegas hotel, police said.

Police said Harris fired several rounds into a Maserati that was being driven by Cherry as both vehicles continued northbound on glitzy Las Vegas Boulevard.

The rapper's expensive sports car careened out of control after he was shot, slamming into several cars, including a taxi. The impact caused the cab to burst into flames, killing the driver, Michael Boldon and a female passenger. Witnesses said it looked like the car exploded.

"He was a number one guy," Carolyn Jean Trimble, Boldon's sister, told ABC News.

"I looked out my window and I could see one vehicle down here on the corner of the intersection totally engulfed in flames," witness John Lamb told ABC News.

Boldon, 62, and his passenger, who has not yet been identified, were both killed, as was Clutch.

Timble said her brother loved driving his taxi around Vegas.

"He came to live with me in Las Vegas last year to help take care of our mother, and the first day he got here he said, 'I have to get a job.' The second day, I came home from work, and he said he got a job," she recalled.

"He says, 'You'll never guess what it is,' and I said, 'what,' and he said, 'taxi cab driver,' and we both fell out laughing," Trimble said. "He loved that job. He never complained. He'd come home and tell me stories about what happened, who he picked up."

Boldon was a single father who raised a 36-year-old son and was a new grandfather. His grandson was named after him, Trimble said.

"Of all the people to take from this earth," she said. "But I guess the Lord needed him."

A passenger in the Maserati was hit and sustained only a minor injury to his arm. Clutch died at University Medical Center.

His father, Kenneth Cherry Sr., expressed his grief for the loss of his son while speaking with ABC News.

"This is something you never really, really ever want to experience as a parent, to lose a child before you go," he said.

Harris is described as 5-foot-11 and 180 pounds. Anyone with information is asked to contact the Las Vegas Metro Police Department's homicide division.

Rusty rocks reveal ancient origin of photosynthesis

SUN-WORSHIP began even earlier than we thought. The world's oldest sedimentary rocks suggest an early form of photosynthesis may have evolved almost 3.8 billion years ago, not long after life appeared on Earth.

A hallmark of photosynthesis in plants is that the process splits water and produces oxygen gas. But some groups of bacteria oxidise substances like iron instead – a form of photosynthesis that doesn't generate oxygen. Evolutionary biologists think these non-oxygen-generating forms of photosynthesis evolved first, giving rise to oxygen-generating photosynthesis sometime before the Earth's atmosphere gained oxygen 2.4 billion years ago (New Scientist, 8 December 2012, p 12).

But when did non-oxygen-generating photosynthesis evolve? Fossilised microbial mats that formed in shallow water 3.4 billion years ago in what is now South Africa show the chemical fingerprints of the process. However, geologists have long wondered whether even earlier evidence exists.

The world's oldest sedimentary rocks – a class of rock that can preserve evidence of life – are a logical place to look, says Andrew Czaja of the University of Cincinnati in Ohio. These rocks, which are found in Greenland and date back almost 3.8 billion years, contain vast deposits of iron oxide that are a puzzle. "What could have formed these giant masses of oxidised iron?" asks Czaja.

To investigate, he analysed the isotopic composition of samples taken from the oxidised iron. He found that some isotopes of iron were more common than they would be if oxygen gas was indiscriminately oxidising the metal. Moreover, the exact isotopic balance varied subtly from point to point in the rock.

Both findings make sense if photosynthetic bacteria were responsible for the iron oxide, says Czaja. That's because these microbes preferentially oxidise only a small fraction of the dissolved iron, and the iron isotopes they prefer vary slightly as environmental conditions change (Earth and Planetary Science Letters, doi.org/kh5). His findings suggest that this form of photosynthesis appeared about 370 million years earlier than we thought.

It is "the best current working hypothesis for the origin of these deposits", says Mike Tice of Texas A&M University in College Station – one of the team who analysed the 3.4-billion-year-old microbial mats from South Africa.

William Martin at the University of Düsseldorf, Germany, agrees. "Anoxygenic photosynthesis is a good candidate for the isotope evidence they see," he says. "Had these fascinating results been collected on Mars, the verdict of the jury would surely remain open," says Martin Brasier at the University of Oxford. "But [on Earth] opinion seems to be swinging in the direction of non-oxygen-generating photosynthesis during the interval from 3.8 to 2.9 billion years ago."

China reports second fatal case of bird flu this year

BEIJING: A man in southwestern China has died of bird flu, health authorities said Saturday, becoming the second fatality from the H5N1 virus this year.

The 31-year-old died in hospital in the city of Guiyang on Friday, the Guizhou province health department said in a statement, adding that no other human cases of avian flu had been reported in the province.

Another city resident, a 21-year-old woman, died from the virus earlier this month.

The Xinhua news agency said both of them had come into close contact with birds but it was not known if the cases were related.

The H5N1 virus typically spreads from birds to humans through direct contact, but experts fear it could mutate into a form transmissible between humans with the potential to trigger a pandemic.

More than 365 people have died of bird flu globally since the virus re-emerged in 2003, according to the World Health Organization.

Its figures show that China saw 25 deadly cases of the virus between 2003 and 2009 before numbers tailed off to one fatality in each of the three following years. The deadliest year of the past decade in China saw eight deaths in 2006.

China is considered one of the nations most at risk from bird flu epidemics because it has the world's biggest poultry population and many chickens in rural areas are kept close to humans.

China has in the past been accused of covering up the extent of bird flu outbreaks, exacerbating fears when new cases are reported.

Separate outbreaks among birds were reported last year in the northern region of Ningxia and the remote northwestern region of Xinjiang, prompting massive culls of chickens.

  Planetary nebula Sh2-174 "blooms" like a rose in a picture released this week by the National Optical Astronomy Observatory (NOAO).

  Nebulae are created when low-mass stars shed their outer layers at the end of their lives. The core of the dying star, called a white dwarf, usually remains at the center of the nebula.

  But not so for the oddly positioned Sh2-174: Its white dwarf is located in the right part of the nebula, in the blue gas pictured above. (See more nebula pictures.)

Cyberattacks Bring Attention to Security Reform

Recent accusations of a large-scale cyber crime effort by the Chinese government left many wondering what immediate steps the president and Congress are taking to prevent these attacks from happening again.

On Wednesday, the White House released the administration's Strategy on Mitigating the Theft of U.S. Trade Secrets as a follow-up to the president's executive order. The strategy did not outwardly mention China, but it implied U.S. government awareness of the problem.

"We are taking a whole of government approach to stop the theft of trade secrets by foreign competitors or foreign governments by any means -- cyber or otherwise," U.S. Intellectual Property Enforcement Coordinator Victoria Espinel said in a White House statement.

As of now, the administration's strategy is the first direct step in addressing cybersecurity, but in order for change to happen Congress needs to be involved. So far, the Cyber Intelligence Sharing and Protection Act (CISPA) is the most notable Congressional legislation addressing the problem, despite its past controversy.

Last April, CISPA was introduced by House Intelligence Committee Chairman Mike Rogers, R-Mich., and Rep. Dutch Ruppersberger, D-Md. The act would allow private companies with consumer information to voluntarily share those details with the NSA and the DOD in order to combat cyber attacks.

The companies would be protected from any liabilities if the information was somehow mishandled. This portion of the act sounded alarm bells for CISPA's opponents, like the ACLU, which worried that this provision would incentivize companies to share individuals' information with disregard.

CISPA passed in the House of Representatives, despite a veto threat from the White House stemming from similar privacy concerns. The bill then died in the Senate.

This year, CISPA was reintroduced the day after the State of the Union address during which the president declared an executive order targeting similar security concerns from a government standpoint.

In contrast to CISPA, the executive order would be initiated on the end of the government, and federal agencies would share relevant information regarding threats with private industries, rather than asking businesses to supply data details. All information shared by the government would be unclassified.

At the core of both the executive order and CISPA, U.S. businesses and the government would be encouraged to work together to combat cyber threats. However, each option would clearly take a different route to collaboration. The difference seems minimal, but has been the subject of legislative debates between the president and Congress for almost a year, until now.

"My response to the president's executive order is very positive," Ruppersberger told ABC News. "[The president] brought up how important information sharing is [and] by addressing critical infrastructure, he took care of another hurdle that we do not have to deal with."

Addressing privacy roadblocks, CISPA backers said the sharing of private customer information with the government, as long as personal details are stripped, is not unprecedented.

"Think of what we do with HIPAA in the medical professions; [doctors do not need to know] the individual person, just the symptoms to diagnose a disease," Michigan Gov. John Engler testified at a House Intelligence Committee hearing in an attempt to put the problem into context.

Mood-sensing smartphone tells your shrink how you feel

PEOPLE with anxiety, depression or stress are often asked to record their mood changes throughout the day, helping psychologists fine-tune their treatment. But they often forget, recording only sparse information at best. Now an emotion-sensing smartphone app that automatically generates someone's "mood diary" could give psychologists all the data they need.

It's the brainchild of Matt Dobson and Duncan Barclay, founders of speech recognition firm EI Technologies, based in Saffron Walden, UK. Instead of relying on people writing diaries, the app, called Xpression, listens for telltale changes in a person's voice that indicate whether they are in one of five emotional states: calm, happy, sad, angry or anxious/frightened. It then lists a person's moods against the times they change, and automatically emails the list to their psychologist at the end of the day.

To work, the app has to be always on, listening out for the user's voice once every second, whether they are talking to family, friends, colleagues or even pets. It also listens in on phone calls. If the user is silent, the app does nothing. Crucially for the users' privacy, it doesn't record their words, instead seeking out telltale acoustic features – like pitch – that are indicative of emotional state.

This kind of emotion recognition via voice pattern already works well and is a "hot area" of research, says Stephen Cox, head of the speech processing lab at the University of East Anglia in Norwich, UK, who is scientific adviser for the firm.

Initially, Xpression will send 200-millisecond-long acoustic snapshots to a remote server where a machine-learning system will work out a person's emotional state before sending it back to the app for storage. Factors like voice loudness, intensity, changes in pitch and speaking pace allow the system to accurately estimate somebody's emotional state. "We extract acoustic features and let the machine-learning system work it out," says Cox. This ability will be built into the app itself eventually, says Dobson.

There's a strong need for this kind of technology, says Adrian Skinner, a clinical psychologist with the UK's National Health Service in Harrogate, North Yorkshire. "With conditions like depression, people tend to stop doing things like filling in mood diaries. If this app gives us more complete diaries it could help us better find the day-to-day triggers that raise or lower a patient's mood," he says.

The firm is a finalist in a UK government competition to identify the nation's top mobile tech company, to be judged on 26 February. An insurance company has already expressed an interest in using the app to ensure the workplace stress therapy it pays for is effective. Clinical trials are due to take place later this year.

Cricket: Hyderabad Test still on, says Australia chief

SYDNEY: Australia plan to play the second Test against India in Hyderabad as scheduled next week despite deadly bomb attacks in the city on the eve of the Test series opener, reports said on Friday.

The twin blasts on Thursday killed 14 people and wounded dozens more in a busy neighbourhood in the southern Indian city, raising questions over whether Australia would play the second Test starting on March 2.

But Cricket Australia chief executive James Sutherland told Fairfax newspapers the match was still on as planned as Australia prepared for the opening match in the four-Test series in Chennai starting later Friday.

"As far as I'm concerned we are playing the second Test in Hyderabad next week. That's where we are at," said Sutherland, who is with the team in Chennai.

Sutherland told Fairfax he was happy to continue to Hyderabad where the team is scheduled to arrive on Wednesday.

"We've got great confidence in the BCCI (Board of Control for Cricket in India) and the relevant authorities here to be able to prepare as best as possible for whatever issues may change from day to day," he said.

"We're very comfortable with everything that has been done so far on this tour."

"We'll obviously take advice from relevant authorities and work with the BCCI and others here to make assessments around Hyderabad but at the same time plans have been in place for a long time," Sutherland said.

"At this stage I wouldn't be calling into question things going ahead in Hyderabad."

He added that team manager Gavin Dovey had sent players text messages overnight updating them on the blasts and that security had been stepped up.

Dozens of extra police reportedly surrounded the Chennai hotel where the Australian and Indian teams are staying.

Captain Michael Clarke said his players were focused on the Chennai game.

"From the team's point of view, our focus is wholly and solely on the field because we've got people off the field who are experts in what is going on. We'll be advised by them," he said.

"Our thoughts and prayers are with all the people of Hyderabad who have been affected."

Earlier, media reports raised doubts over the tour.

"Australia's cricket tour of India has been plunged into uncertainty," said the Herald-Sun newspaper, while the Sydney Morning Herald carried a headline "Hyderabad Test in doubt as bombings rock city".

Australia pulled out of a tour to Pakistan in 2008 over security concerns after a series of bombings in the troubled country. They also refused to play any matches in the 1996 World Cup in Sri Lanka after bombings there.

Cricket Australia, which said the safety of players was paramount, earlier said the tourists had received "no information to suggest there is any threat to the team" but that talks were ongoing.

The attacks targeted a Hindu district in the city, a hub of India's computing industry in the southern state of Andhra Pradesh, home to local offices of Google and Microsoft among other Western IT companies.

After the blasts, the Foreign Affairs Department in Canberra warned Australians following the tour in India that terror attacks could happen anywhere.

"We advise you to exercise a high degree of caution in India at this time because of the risk of terrorism, civil unrest, crime and vehicle accidents," the department said.

"Terrorist attacks could occur anywhere at any time in India with little or no warning," it said.

"Possible targets include public places in New Delhi, Mumbai and other major cities, and Indian security and political interests."

However, the overall level of advice for Australians in India has not changed, with the department recommending people exercise a high degree of caution.

No major international cricket has been played in Pakistan since a deadly attack on the Sri Lankan team bus by armed militants in Lahore in 2009.

Zendesk hack snares user data from Twitter, Tumblr, Pinterest

At a time when it seems no company is immune from hackers, user information from three high-profile social-networking sites has been compromised due to a hack at another company.

Customer support service Zendesk revealed today that it had been the victim of a security breach and that information from three of its clients had been downloaded. As first reported by Wired, those three clients are Twitter, Pinterest, and Tumblr.

Zendesk revealed the hack in a company blog post today that said the vulnerability was immediately identified and patched.

Our ongoing investigation indicates that the hacker had access to the support information that three of our customers store on our system. We believe that the hacker downloaded email addresses of users who contacted those three customers for support, as well as support email subject lines. We notified our affected customers immediately and are working with them to assist in their response.

Although Zendesk did not identity the clients by name, some users of the social-networking services began receiving warnings that they may have been affected by the breach. Wired published warnings sent by each company that identified Zendesk as the point of the leak.

One e-mail sent by Tumblr to a CNET associate said hackers may have had access to the subject lines and e-mail addresses of messages sent to Tumblr support.

The subject lines of your emails to Tumblr Support may have included the address of your blog which could potentially allow your blog to be unwillingly associated with your email address.

Any other information included in the subject lines of emails you've sent to Tumblr Support may be exposed. We recommend you review any correspondence you've addressed to support@tumblr.com, abuse@tumblr.com, dmca@tumblr.com, legal@tumblr.com, enquiries@tumblr.com, or lawenforcement@tumblr.com.

Founded in 2007, the cloud-based customer service solution provider announced last month that it had signed up its 25,000th customer.

The hacks come just days after Apple and Facebook revealed that their respective employees' computers fell victim to unauthorized access.

Oldest Known Wild Bird Hatches Chick at 62

Wisdom, the oldest known wild bird, has yet another feather in her cap—a new chick.

The Laysan albatross (Phoebastria immutabilis)—62 years old at least—recently hatched a healthy baby in the U.S. Midway Atoll National Wildlife Refuge, her sixth in a row and possibly the 35th of her lifetime, according to the U.S. Geological Survey's (USGS) North American Bird Banding Program. (Related: "51-Year-Old Albatross Breaks N. American Age Record [2003].")

But Wisdom's longevity would be unknown if it weren't for a longtime bird-banding project founded by USGS research wildlife biologist Chandler Robbins.

Now 94, Robbins was the first scientist to band Wisdom in 1956, who at the time was "just another nesting bird," he said. Over the next ten years, Robbins banded tens of thousands of black-footed albatrosses (Phoebastria nigripes) and Laysan albatrosses as part of a project to study the behavior of the large seabirds, which at the time were colliding with U.S. Navy aircraft.

Robbins didn't return to the tiny Pacific island—now part of the U.S. Papahānaumokuākea Marine National Monument—until 2002, when he "recaptured as many birds as I could in hopes that some of them would be the old-timers."

Indeed, Robbins did recapture Wisdom—but he didn't know it until he got back to his office at the Patuxent Wildlife Research Center in Laurel, Maryland, and checked her band number in the database.

"That was real exciting, because we didn't think the chances of finding one that old would be that good," Robbins said Wednesday in an interview from his office at the Patuxent center, where he still works.

Albatrosses No Bird Brains

Bigger birds such as the albatross generally live longer than smaller ones: The oldest bird in the Guinness Book of Animal Records, a Siberian white crane (Leucogeranus leucogeranus), lived an unconfirmed 82 years. Captive parrots are known to live into their 80s. (See National Geographic's bird pictures.)

The Laysan albatross spends most of the year at sea, nesting on the Midway Atoll (map) in the colder months. Birds start nesting around five years of age, which is how scientists knew that Wisdom was at least five years old in 1956.

Because albatrosses defend their nests, banding them doesn't require a net or a trap as in the case of other bird species, Robbins said—but they're far from tame.

"They've got a long, sharp bill and long, sharp claws—they could do a job on you if you're not careful how to handle them," said Robbins, who estimates he's banded a hundred thousand birds.

For instance, "when you're not looking, the black-footed albatross will sneak up from behind and bite you in the seat of the pants."

But Robbins has a fondness for albatrosses, and Wisdom in particular, especially considering the new dangers that these birds face.

Navy planes are no longer a problem—albatross nesting dunes were moved farther from the runway—but the birds can ingest floating bits of plastic that now inundate parts of the Pacific, get hooked in longlines meant for fish, and be poisoned by lead paint that's still on some of Midway Atoll's buildings. (Also see "Birds in 'Big Trouble' Due to Drugs, Fishing, More.")

That Wisdom survived so many years avoiding all those hazards and is still raising young is quite extraordinary, Robbins said.

"Those birds have a tremendous amount of knowledge in their little skulls."

"Simply Incredible"

Wisdom's accomplishments have caught the attention of other scientists, in particular Sylvia Earle, an oceanographer and National Geographic Explorer in Residence, who said by email that Wisdom is a "symbol of hope for the ocean." (National Geographic News is part of the National Geographic Society.)

Earle visited Wisdom at her nest in January 2012, where she "appeared serenely indifferent to our presence," Earle wrote in the fall 2012 issue of the Virginia Quarterly Review.

"I marveled at the perils she had survived during six decades, including the first ten or so years before she found a lifetime mate. She learned to fly and navigate over thousands of miles to secure enough small fish and squid to sustain herself, and every other year or so, find her way back to the tiny island and small patch of grass where a voraciously hungry chick waited for special delivery meals."

Indeed, Wisdom has logged an estimated two to three million miles since 1956—or four to six trips from Earth to the moon and back, according to the USGS. (Related: "Albatross's Effortless Flight Decoded—May Influence Future Planes.")

Bruce Peterjohn, chief of the North American Bird Banding Program, called Wisdom's story "simply incredible."

"If she were human, she would be eligible for Medicare in a couple years—yet she is still regularly raising young and annually circumnavigating the Pacific Ocean," he said in a statement.

Bird's-Eye View

As for Robbins, he said he'd "love to get out to Midway again." But in the meantime, he's busy going through thousands of bird records in an effort to trace their life histories.

There's much more to learn: For instance, no one has ever succeeded in putting a radio transmitter on an albatross to follow it throughout its entire life-span, Robbins noted.

"It would be [an] exciting project for someone to undertake, but I'm 94 years old," he said, chuckling. "It wouldn't do much for me to start a project at my age."

Arias Challenged On Pedophilia Claim

Accused murderer Jodi Arias was challenged today by phone records, text message records, and her own diary entries that appeared to contradict her claim that she caught her ex-boyfriend, Travis Alexander, looking at pictures of naked boys.

Arias had said during her testimony that one afternoon in January 2008, she walked in on Alexander masturbating to pictures of naked boys. She said she fled from the home, threw up, drove around aimlessly, and ignored numerous phone calls from Alexander because she was so upset at what she had seen.

The claim was central to the defense's accusation that Alexander was a "sexual deviant" who grew angry and abusive toward Arias in the months after the incident, culminating in a violent confrontation in June that left Alexander dead.

Arias claimed she killed him in self-defense. She could face the death penalty if convicted of murder.

Catching Up on the Trial? Check Out ABC News' Jodi Arias Trial Coverage

Today, prosecutor Juan Martinez, who has been aggressive in questioning witnesses throughout the trial, volleyed questions at her about the claim of pedophilia, asking her to explain why her and Alexander's cell phone records showed five calls back and forth between the pair throughout the day she allegedly fled in horror. Some of the calls were often initiated Arias, according to phone records.

She and Alexander also exchanged text messages throughout the afternoon and evening at a time when Arias claims the pedophilia incident occurred. In those messages they discuss logistics of exchanging one another's cars that night. Alexander sends her text messages about the car from a church social event he attended that night that she never mentioned during her testimony.

Arias stuck by her claim that she saw Alexander masturbating to the pictures, and her voice remained steady under increasingly-loud questioning by Martinez.

But Martinez also sparred with Arias on the stand over minor issues, such as when he asked Arias detailed questions about the timing and order of events from that day and Arias said she could not remember them.

"It seems you have problems with your memory. Is this a longstanding thing? Since you started testifying?" Martinez asked.

"No it goes back farther than that. I don't know even know if I'd call it a problem," Arias said.

"How far back does it go? You don't want to call them problems, are they issues? Can we call them issues? When did you start having them?" he asked in rapid succession. "You say you have memory problems, that it depends on the circumstance. Give me the factors that influence that."

"Usually when men like you or Travis are screaming at me," Arias shot back from the stand. "It affects my brain, it makes my brain scramble."

"You're saying it's Mr. Martinez's fault?" Martinez asked, referring to himself in the third person.

"Objection your honor," Arias' attorney finally shouted. "This is a stunt!"

Timeline of the Jodi Arias Trial

Martinez dwelled at one point about a journal entry where Arias wrote that she missed the Mormon baptism of her friend Lonnie because she was having kinky sex with Alexander. He drew attention to prior testimony that she and Alexander used Tootsie Pops and Pop Rocks candy as sexual props.

"You're trying to get across (in the diary entry) that this involved a sexual liaison with Mr. Alexander right?" he asked. "And you're talking about Tootsie Pops and Pop Rocks?"

"That happened also that night," Arias said.

"You were there, enjoying it, the Tootsie Pops and Pop Rocks?" he asked again, prompting a smirk from Arias.

"I enjoyed his attention," Arias said.

Higgs may spell doom, unless supersymmetry saves us

Lisa Grossman, physical sciences reporter

(Image: CERN)

Is the Higgs boson a herald of the apocalypse? That's the suggestion behind a theory, developed more than 30 years ago, that is back in the headlines this week. According to physicists, the mass of the Higgs-like particle announced last summer supports the notion that our universe is teetering on the edge of stability, like a pencil balanced on its point.

"It may be that the universe we live in is inherently unstable," Joseph Lykken, of the Fermi National Accelerator Laboratory in Batavia, Illinois, said on Monday at a meeting of the American Association for the Advancement of Science. "At some point, billions of years from now, it's all going to be wiped out."

Physicists have been wringing their hands about this scenario since 1982, when theorists Michael Turner and Frank Wilczek published a paper about it in Nature, NBC News points out. The pair showed that the vacuum of space can be in different energy states, and it will be most stable at its lowest energy. Trouble arises if we're not there yet, and we're inhabiting a temporarily stable state that should ultimately collapse.

"The universe wants to be in a different state, so eventually to realize that, a little bubble of what you might think of as an alternate universe will appear somewhere, and it will spread out and destroy us," Lykken said at AAAS.

Enter the Higgs boson, the particle form of the field that gives mass to several fundamental particles. The Higgs field permeates the vacuum of space, which means the mass of the boson and the stability of the vacuum are closely intertwined. Theory predicted that if the Higgs boson is heavier than about 129 gigaelectronvolts (GeV), the universe should be on safe footing.

But in July 2012 physicists at CERN, near Geneva, Switzerland announced that a particle closely matching the Higgs had been found by experiments in the Large Hadron Collider (LHC). The much celebrated particle has a mass of about 126 GeV - light enough to raise fears of instability.

There is still hope for the universe as we know it. Some theorists pointed out that the relationship between the Higgs mass and the vacuum of space depends on the mass of a particle called the top quark. If the top quark's mass is different than we think it is, stability might reign.

There are also anomalies with the Higgs measurement, like the fact that it decays into photons more often than predicted. That hints we may yet find particles from the theory of supersymmetry, which says each ordinary particle has heavier "superpartners". If the Higgs has such a relative, it might save us from destruction. But some of these predicted particles, particularly the superpartners of the top quark, can push the universe back into instability.

The worries may remain unconfirmed for a while. The LHC is shutting down for a two-year break so engineers can prepare the machine to shoot higher-energy particle beams, which are needed to probe for superpartners.

Oscar hopeful Haneke fears failure with Mozart

MADRID: Although he is nursing hopes of an Oscar, Austrian film-maker Michael Haneke says he feels doomed to failure with his latest project -- a staging of a Mozart opera in Spain.

"Amour", Haneke's film about an ageing couple that won the Palme d'Or at Cannes last year, is up for five Oscars on Sunday, including for best film and best director.

First, however, the 69-year-old faces another big night -- Saturday's premier of "Cosi Fan Tutte", by his fellow Austrian at Madrid's Teatro Real.

"With Mozart you are condemned to fail. The question is on what level," Haneke, considered one of the greatest and most uncompromising living film-makers, told reporters in Madrid on Wednesday.

"I don't much like talking about opera. I prefer to talk about my films. I see myself more as a film director."

The Madrid show is his second opera project after "Don Giovanni" in Paris in 2007, and "probably my last" before returning to film-making, he added.

"After 'Don Giovanni' I received about 15 offers to direct operas but I rejected them all because I didn't think I was the right person to do them," he said.

Haneke's films such as "The White Ribbon" -- a macabre tale of pre-war Germany for which he won the first of his two Palmes D'Or -- have earned him a reputation for painful subjects.

"Cosi Fan Tutte" is ostensibly a romantic comedy -- the tale of two women who are tricked and tested by their suitors -- but the theatre says its meditation on love and loyalty has its hard side too.

Written by a depressed Mozart when he was having love pains of his own, "Cosi Fan Tutte" is one of the composer's most challenging operas to stage, said the theatre's Belgian director Gerard Mortier.

"It is the most profound and difficult Mozart, with some extraordinarily difficult arias," he said.

Haneke has stage-directed the opera in Madrid under the musical baton of French conductor Sylvain Cambreling.

"Amour" meanwhile examines the intimate life of an elderly man and his dying wife.

"It touches people because it could happen to any family," Haneke said.

"If you are young it could happen to your grandparents. If you're less young, to your parents. And if you're even less young, it could happen to you."

The film is nominated for Oscars in the best film, director, actress, script and foreign film categories.

"I would like to win them all. I would hope to win at least one -- any of them," he said. "I am crossing my fingers."

Making sense of the PS4 game lineup

NEW YORK--So the world didn't exactly get what it wanted out of Sony's PlayStation 4 debut tonight. There was no sight of the actual console itself and details about its specific release date and price were also nowhere to be seen.

Sony's team-up with Gaikai is sure to net some interesting ideas and implementations with cloud streaming, the sharing of game screens, remote play and other concoctions, but it was the games themselves that made the biggest impact.

Those pondering the PS4's gaming prowesses were served an interesting dish. 10 or so major developers were represented in some capacity and on hand to discuss their progress with the new hardware, which consisted of all sorts of fresh media. Some announced new exclusive titles, while others merely showcased proof of concept videos.

So how do these new tidbits of information playout in the grand scheme of things? How does this impact the current PS3 ecosystem and what we (up until now) thought was a concrete list of upcoming software?

Let's take a closer look at each presentation and dig a little deeper. Here are the exclusives:

The first game to debut was Knack, a title being directed by Mark Cerny, who's also the lead on the PS4's hardware. Knack looks like a platform-action title in the vein of Ratchet & Clank or Jak & Daxter and will be an exclusive PS4 title.

Guerilla Games' next chapter in the Killzone series will be called Shadow Fall. The audience in New York was treated to visually brilliant flythrough that eventually morphed into an actual demo of the game being played live. It was loud, violent and ultimately not much of a departure from previous titles in the franchise. However, the big takeaway here is that Shadow Fall's massive scope and size could only be achieved on next-gen hardware.

From the studio that brought us MotorStorm, the next exclusive to debut was DriveClub, a game that looks to create a never-before-seen racing experience by painstakingly recreating every last possible detail of racing machines. There's also a focus here on multiplayer, specifically 3-on-3 racing.

Next up was inFamous: Second Son, the next-gen effort from Sucker Punch, the studio behind the PS3's duo of inFamous games. Second Son looks to build upon the inFamous universe where normal human beings evolve to harness supernatural powers. Some heavy-duty themes of the cost of freedom and privacy issues came to play in this debut.

Media Molecule, the makers of LittleBigPlanet, showed off some interesting technology as well. Citing the mantra of "the tyranny of the polygon," the team teased what their next project would be by demonstrating the use of a Move controller to sculpt 3D objects and characters in a virtual world.

Wrapping up the short list of announced exclusives was a quick presentation from David Cage, the founder of developer Quantic Dream. His new game, Beyond: Two Souls was announced at last year's E3, but Cage certainly made it seem that the title would see a PS4 release. It's here where we're starting to see a blurring of the PS3/PS4 release calendar and the first of what could be many PS3 titles that actually become PS4 bound.

Indie games had a great night too. Jonathan Blow, the creator of the hit, Braid, was on hand to talk about his next title, The Witness. This wasn't necessarily an announcement, but rather a chance for the world to see much more of a game that doesn't necessarily follow the same formula as most mainstream titles. The Witness will launch along with the PS4, but only with a timed exclusivity.

What followed after Blow's segment was a parade of third party developers chatting up what their studio's were cooking up for PlayStation 4. It's safe to assume these titles will most likely not be totally exclusive to Sony's system.

Capcom unveiled its next-gen engine, codenamed Panta Rhei, and the first title to be released built upon it. Tentatively titled Deep Down, the game looks like it will be some sort of dungeon-raiding adventure title complete with fire-breathing dragons, in-game slo-mo sequences and gorgeous texture renderings.

Next up was publisher Square Enix showing off the Luminous Studio engine which was used to provide the attending audience with more of a "what's possible" using PS4 hardware. There was no specific game being announced here, just an over-the-top sequence of magic, gunfighting and brilliant visuals.

Ubisoft's time on stage was spent providing a real-time demo of Watch Dogs, the current-gen turned next-gen title that will officially be a PS4 game. Arguably the best demo of the evening, Watch Dogs presents a world where players can hack almost anything in the world around them, using circuit breakers as booby traps and stalling trains to their advantage.

Blizzard Entertainment made a brief presentation announcing that Diablo III would appear on both the PS3 and PS4.

Finally, Activision spent a few minutes discussing developer Bungie's first foray outside of Microsoft's console, announcing that Destiny will also be a PS3 and PS4 title.

It's tough to completely wrap our heads around the PS3 release calendar and how it will overlap with PS4's. Because the PS4 will not be backwards compatible with PS3 games directly, it's created what is going to be a strange transitional period where we have games available on both platforms. How Gaikai's streaming technology comes into play with PS3 backwards compatibility has still yet to be definitively outlined.

Hopefully this wrap-up provides a bit of clarity to what was certainly an evening of scattered information. It's not worth hoping for things to get much clearer from now until this summer's E3, which should shed much more light on these titles and more.

NASA's Mars Rover Makes Successful First Drill

For the first time ever, people have drilled into a rock on Mars, collecting the powdered remains from the hole for analysis.

Images sent back from NASA's Mars rover Curiosity on Wednesday confirmed that the precious sample is being held by the rover's scoop, and will soon be delivered to two miniature chemical labs to undergo an unprecedented analysis. (Related: "Mars Rover Curiosity Completes First Full Drill.")

To the delight of the scientists, the rock powder has come up gray and not the ubiquitous red of the dust that covers the planet. The gray rock, they believe, holds a lot of potential to glean information about conditions on an early Mars. (See more Mars pictures.)

"We're drilling into rock that's a time capsule, rocks that are potentially ancient," said sampling-system scientist Joel Hurowitz during a teleconference from NASA's Jet Propulsion Laboratory in California.

A Place to Drill

The site features flat bedrock, often segmented into squares, with soil between the sections and many round gray nodules and white mineral veins.

Hurowitz said that the team did not attempt to drill into the minerals or the gray balls, but the nodules are so common that they likely hit some as they drilled down 2.5 inches (6.3 centimeters).

In keeping with the hypothesis that the area was once under water, Hurowitz said the sample "has the potential of telling us about multiple interactions of water and rock."

The drill, located at the end of a seven-foot (two-meter) arm, requires precision maneuvering in its placement and movement, and so its successful initial use was an exciting and welcome relief. The rover has been on Mars since August, and it took six months to find the right spot for that first drill. (Watch video of the Mars rover Curiosity.)

The flat drilling area is in the lower section of Yellowknife Bay, which Curiosity has been exploring for more than a month. What was previously identified by Curiosity scientists as the dry bed of a once-flowing river or stream appears to fan out into the Yellowknife area.

The bedrock of the site—named after deceased Curiosity deputy project manager John Klein—is believed to be siltstone or mudstone. Scientists said the veins of white minerals are probably calcium sulfate or gypsum, but the grey nodules remain something of a mystery.

Triumph

To the team that designed and operates the drill, the results were a triumph, as great as the much-heralded landing of Curiosity on the red planet. With more than a hundred maneuvers in its repertoire, the drill is unique in its capabilities and complexities. (Watch video of Curiosity's "Seven Minutes of Terror.")

Sample system chief engineer Louise Jandura, who has worked on the drill for eight years, said the Curosity team had made eight different drills before settling on the one now on the rover. The team tested each drill by boring 1,200 holes on 20 types of rock on Earth.

She called the successful drilling "historic" because it gives scientists unprecedented access to material that has not been exposed to the intense weathering and radiation processes that affect the Martian surface.

Mini-laboratories

The gray powder will be routed to the two most sophisticated instruments on Curiosity—the Sample Analysis at Mars (SAM) and Chemistry and Mineralogy (CheMin).

SAM, the largest and most complex instrument onboard, operates with two ovens that can heat the sample up to 1,800°F (982°C), turning the elements and compounds in the rock into gases that can then be identified. SAM can also determine whether any carbon-based organic material is present.

Organics are the chemical building blocks of life on Earth. They are known to regularly land on Mars via meteorites and finer material that rains down on all planets.

But researchers suspect the intense radiation on the Martian surface destroys any organics on the surface. Scientists hope that organics within Martian rocks are protected from that radiation.

CheMin shoots an X-ray beam at its sample and can analyze the mineral content of the rock. Minerals provide a durable record of environmental conditions over the eons, including information about possible ingredients and energy sources for life.

Both SAM and CheMin received samples of sandy soil scooped from the nearby Rocknest outcrop in October. SAM identified organic material, but scientists are still trying to determine whether any of it is Martian or the byproduct of organics inadvertently brought to Mars by the rover. (See "Mars Rover Detects Simple Organic Compounds.")

In the next few days, CheMin will be the first to receive samples of the powdered rock, and then SAM. Given the complexity of the analysis, and the track record seen with other samples, it will likely be weeks before results are announced.

The process of drilling and collecting the results was delayed by several glitches that required study and work-arounds. One involved drill software and the other involved a test-bed problem with a sieve that is part of the process of delivering samples to the instruments.

Lead systems engineer Daniel Limonadi said that while there was no indication the sieve on Mars was malfunctioning, they had become more conservative in its use because of the test bed results. (Related: "A 2020 Rover Return to Mars?")
