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."

Indian PM calls for calm after deadly Hyderabad blasts






NEW DELHI: Indian Prime Minister Manmohan Singh on Sunday appealed for calm as he flew to Hyderabad and visited some of the 117 people wounded in twin bombings last week which killed 16 people.

Singh also visited the blast site in Dilsukh Nagar, where two bicycle bombs exploded within a few minutes of each other outside a cinema and near a bus stand on Thursday evening.

The prime minister met with some of the blast survivors and medical staff in two city hospitals and expressed his condolences.

"It is most important that in this hour of grief the people should maintain calm," he said.

"I am happy that the people of Hyderabad have refused to be provoked by this nefarious incident," the prime minister told reporters.

"I pray for the speedy recovery of those who have been injured, to those who have died I send my condolences to all the bereaved families," Singh added.

His spokesman Pankaj Pachauri told AFP Singh was scheduled to be briefed by N. Kiran Kumar Reddy, chief minister of the southern state of Andhra Pradesh, on the incident.

Hyderabad, one of the major hubs of India's booming software industry, is the capital of coastal Andhra Pradesh.

The premier has vowed to bring to justice the perpetrators of what he called a "dastardly" attack, the first major bombings in India since 2011.

His Congress Party-led government was criticised in parliament on Friday by the opposition, which said the bombings had exposed systemic security failures at a time when India is on heightened alert.

India's main opposition BJP party mocked the premier's one-day trip to Hyderabad saying the blasts were a result of the Indian government's failure to tackle terrorism.

"The prime minister's visit to Hyderabad is a non-event," BJP leader Balbir Punj told reporters in New Delhi.

"In fact, if he and his government had been sensitive to the issue of terrorism in this country... this attack would not have taken place," he said.

Andhra Pradesh Home Minister P. Sabita Indra Reddy has said investigators have found "vital clues" but gave no details.

Newspapers have pointed the finger at the Indian Mujahideen, a banned militant outfit which has claimed responsibility for previous attacks.

The fitting of the explosive devices to bicycles was similar to other attacks by the outfit, local media reports quoted investigators as saying.

The homegrown group has links to Lashkar-e-Taiba, the Pakistan-based militant outfit blamed for the 2008 Mumbai attacks that claimed 166 lives, according to Indian intelligence officials.

New Delhi has long accused its neighbour of aiding and abetting the militant groups who have carried out attacks on Indian soil -- a charge that Pakistan rejects.

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."

Iran won't go beyond nuclear obligations: envoy






TEHRAN: Iran said Saturday it will not go beyond its obligations nor accept anything outside its rights under the non-proliferation treaty, ahead of talks with major powers over its disputed nuclear drive.

"We will not accept anything beyond our obligations and will not accept anything less than our rights," said the Islamic republic's top nuclear negotiator, Saeed Jalili, quoted by ISNA news agency.

"Iran has fulfilled its NPT obligations as an active and committed member, therefore should gain all of its rights," Jalili said in an address to Iranian nuclear industry officials.

His remarks come ahead of a meeting between Iran and six world powers -- Britain, China, France, Russia, the United States and Germany -- in Kazakhstan on Tuesday.

The talks will be the first between the parties since three rounds of meetings in Moscow ended in stalemate in June last year.

The so-called P5+1 called on Iran to scale back on uranium enrichment, the process which used for power plant fuel and in higher purities needed for a nuclear weapon.

But they stopped short of offering Tehran substantial relief from UN Security Council and unilateral Western sanctions that last year began to cause major economic problems for the Gulf country.

Iran denies seeking atomic weapons but many in the international community suspect otherwise.

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.

Spidey-sense suit tingles when someone gets too close









































FOR Peter Parker, it was a tingling sensation that alerted him to an imminent threat. Now anyone can pretend to be Spider-Man by simply donning a suit that lets you feel how close you are to a nearby object. It can even let the wearer navigate with their eyes closed.












The suit, called SpiderSense and built by Victor Mateevitsi of the University of Illinois in Chicago has small robotic arms packaged in modules with microphones that send out and pick up ultrasonic reflections from objects. When the ultrasound detects someone moving closer to the microphone, the arms respond by exerting a growing pressure on the body. Seven of these modules are distributed across the suit to give the wearer as near to 360 degree ultrasound coverage as possible.












"When someone is punching Spider-Man, he feels the sensation and can avoid it. Our suit is the same concept," says Mateevitsi. SpiderSense could help blind people to find their way more easily, he says.












Mateevitsi tested the suit out on students, getting them to stand outside on campus, blindfolded, and "feel" for approaching attackers. Each wearer had ninja cardboard throwing stars to use whenever they sensed someone approaching them. "Ninety five per cent of the time they were able to sense someone approaching and throw the star at them," says Mateevitsi.












"I'm very excited about this," says Gershon Dublon of the Massachusetts Institute of Technology, who also works on augmenting parts of the human body. Mateevitsi's work is a step on the road to giving humans truly integrated extrasensory perception, says Dublon.












Mateevitsi wants to use the suit, or just a few sensors on the arms and back, to boost cyclists' awareness of other traffic on the road. SpiderSense is due to be presented at the Augmented Human conference in Stuttgart, Germany, in March. The team now plans to add more sensors to the suit to increase its resolution.


















"We humans have the senses that we are born with and we can't extend them," Mateevisti says. "But there are some threats which are very deadly, but we can't sense them, like radiation. Electronic sensors can feel those threats."












The team also plans to begin trials of SpiderSense with visually impaired people.

Spate of blasts killed 83 in Damascus' deadliest day






DAMASCUS: A spate of bombings across Damascus killed at least 83 people in the deadliest day for the capital since Syria's war erupted, a watchdog said Friday, as the opposition discussed a plan for peace talks with the regime.

Thursday's biggest bombing, which both the regime and its opponents blamed on "terrorists", killed 61 people and left a trail of destruction in the city centre, said the Syrian Observatory for Human Rights.

The attack, in Mazraa district, was carried out by a suicide bomber who detonated his explosives-laden car near the entrance of the Baath party's main offices, said the Britain-based monitor.

Gruesome images of charred bodies next to mangled vehicles were shown on state television, which said children were among the casualties in the explosion near a school.

The blast wounded more than 200 people in a wide radius, including Nayef Hawatmeh, the head of the Democratic Front for the Liberation of Palestine, which said he was hit by flying glass in his office 500 metres (yards) away.

Russian news agencies reported the windows of Moscow's embassy were blown out, although no staff was hurt.

Another 22 people were killed in an apparently coordinated triple bombing targeting security headquarters in the northern Damascus district of Barzeh on Thursday, including 19 members of the forces, said the Observatory.

Attacks have increasingly targeted government or security buildings in Damascus in recent months, many of them claimed by the jihadist Al-Nusra Front which Washington has designated as a "terrorist" organisation.

The attacks were condemned by both the regime of President Bashar al-Assad and the umbrella opposition National Coalition, as well as the United States, Russia and UN chief Ban Ki-moon.

There was no still claim of responsibility for the Mazraa blast.

The Syrian foreign ministry alleged the bombing was "carried out by armed terrorist groups linked to Al-Qaeda that receive financial and logistic help from abroad", using government terminology for rebels.

The opposition also denounced the bombers as "terrorists".

"Any acts targeting civilians with murder or human rights violations are criminal acts that must be condemned, regardless of the perpetrator or the justification," said the National Coalition.

Elsewhere, 38 people were killed Thursday in Daraa, birthplace of the revolt in the country's south, including 18 in an air raid on a medical centre, said the Observatory.

Also in Daraa, six women and a child all from the same family were killed in an explosion at Tsil, and 10 more civilians died in army shelling of Jassem town.

In the northwestern province of Idlib, where sectarian strife has been rising, 40 Shiites kidnapped by an armed group and 300 Sunnis abducted in reprisals last week were released after mediation talks between families.

The majority of the Syrian population fighting the Assad regime are Sunni Muslims, while the president and his clan belong to the Alawite branch of Shiite Islam.

The attacks added urgency to the National Coalition meeting in Cairo, where discussions will continue later on Friday focused on an offer by its chief to talk directly with the regime.

Coalition chairman Ahmed Moaz al-Khatib has offered to talk to regime officials without "blood on their hands" -- an initiative welcomed by the Arab League and the United States as well as Assad allies Iran and Russia.

But the Syrian National Council, a key part of the Coalition, has rejected any talks until Assad quits, and the regime says it will negotiate only without preconditions.

At the United Nations, Russia accused US diplomats of blocking a Security Council condemnation of the Mazraa attack. Other diplomats said however that Russia had refused to include language criticising Assad.

The UN says at least 70,000 people have been killed in the conflict which was sparked by a bloody regime crackdown on Arab Spring-inspired protests that broke out in March 2011.
