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."

Auto racing: Late crash mars Daytona Nationwide finish

DAYTONA BEACH: A fiery car crash sent Kyle Larson's car airborne and flying debris injured a number of fans Saturday in the waning moments of the NASCAR Nationwide Series season-opener.

The wreck, which occurred almost as Tony Stewart was taking the chequered flag for victory, appeared to begin when Regan Smith was turned sideways and took several competitors behind him in a pack.

Larson, making his first start in the NASCAR stock car second-tier series, then sailed into the catch-fencing.

Larson's car tore a hole in the fence, and his engine sheared off with at least one tire and other debris flying into the stands.

ESPN quoted Daytona Beach police as saying 15 fans were injured, one critically.

"Our prayers and thoughts are with everybody they are working on," NASCAR President Mike Helton said.

Emergency medical personnel immediately went into the stands to treat those hurt, but NASCAR officials could not immediately confirm the number and nature of the injuries. None of the drivers was injured.

"There was obviously some intrusion into the fence, and fortunately with the way the events are equipped, there was plenty of emergency workers ready to go," Helton told ESPN. "They all jumped on it pretty quickly.

"Right now, it's just a function of trying to determine what all damage is done," added Helton, who said some injured fans were being taken to local hospitals.

Another big crash, involving 11 cars, took place with five laps remaining, with driver Michael Annett taken to hospital after hitting a barrier.

"We've always known since racing started this is a dangerous sport," Stewart said. "As much as we want to celebrate, I'm more concerned about the fans and the drivers right now."

Google laptop shows Apple a thing or two

The 3.3-pound Google Chromebook Pixel sports a 12.85-inch, 2,560x1,700-pixel display and an Intel Core i5 processor.

Stephen Shankland/CNET)

Thank you, Google. For obsoleting my MacBook.

Question: What two killer hardware features are missing on MacBooks? My answer: a touch screen and 4G.

What a coincidence. Just what Google is offering on the Chromebook Pixel. And in a package that comes close to matching the MacBook's aesthetics. (I'm focusing strictly on the hardware for the moment.)

Google is saying, at least in the case of touch, hey Apple, you don't get it.

Not everyone may agree with that. Take the laptop flat-earthers. They will say touch is stupid (or "pointless" as one columnist said) on a laptop. Yeah right, just like the mouse was a stupid idea.

Then there's Apple's your-arm-wants-to-fall-off on vertical touch surfaces excuse. That will eventually give way to a touch-screen MacBook of some sort. You heard it here first.

The point is, Google knows (they're not stupid) that touch is important on a laptop. As does Microsoft (Windows 8 and Surface). That leaves Apple in Luddite land.

4G: And some might say that a Chromebook needs 4G more than a MacBook because the Chromebook is so immersed in the cloud. Hmm, my MacBook spends lots of time in the cloud too. And the last time I used it on the road, I was constantly hauling out my Verizon MiFi or running down my iPhone's battery with the Personal Hotspot. Come on, LTE belongs in a laptop.

And the operating system? I believe that cool hardware is the first step in luring consumers to a new operating environment.

While Chrome OS is still a work in progress (and lacks key features that many users need), with the success of
Android, I do think it's possible that an improved Chrome OS combined with a second-generation Chromebook Pixel could reel in more consumers.

Google certainly has my attention.

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."

Fiery Last-Lap Daytona Crash Injures 15 Fans

A fiery last-lap crash at the Daytona International Speedway injured a number of spectators today, who were seen being carried away from the stands on stretchers.

Fifteen spectators were taken to the hospital, according to ESPN, with one on the way to surgery with head trauma.

The 12-car crash happened moments before the end of the Nationwide race, and on the eve of the Daytona 500, one of NASCAR's biggest events.

The crash was apparently triggered when driver Regan Smith's car, which was being tailed by Brad Keselowski on his back bumper, spun to the right and shot up the track. Smith had been in the lead and said after the crash he had been trying to throw a "block."

Rookie Kyle Larson's car slammed into the wall that separates the track from the grandstands, causing his No. 32 car to go airborne and erupt in flames.

When a haze of smoke cleared and Larson's car came to a stop, he jumped out uninjured.

His engine and one of his wheels were sitting in a walkway of the grandstand.

"I was getting pushed from behind," Larson told ESPN. "Before I could react, it was too late."

Driver Michael Annett was taken to the hospital after he slammed head-on into a barrier during the chaos. NASCAR officials told ESPN the driver was awake and alert.

Tony Stewart pulled out the win, but in victory lane, what would have been a celebratory mood was tempered by concern for the injured fans.

"We've always known this is a dangerous sport," Stewart said. 'But it's hard when the fans get caught up in it."

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."

US budget cuts can be avoided: Obama

WASHINGTON: President Barack Obama insisted Friday that mandatory government budget cuts set to kick in on March 1 -- known as the sequester -- were not "inevitable."

The cuts to defence and domestic spending were mandated in an agreement between Obama and his Republican foes to end a previous budget battle.

"I never think that anything is inevitable, we always have the opportunity to make the right decisions," Obama told reporters following a White House meeting with visiting Japanese Prime Minister Shinzo Abe.

"Hope springs eternal."

The consequences of the threatened sequester were supposed to be so punishing that Democrats and Republicans would have no choice but to reach a deal to reduce the deficit.

Obama also attempted to reassure financial markets in case the cuts do go forward.

"Unlike issues like the debt ceiling, the sequester going into effect will not threaten the world financial system, it's not the equivalent of the US defaulting on its obligations," Obama said.

"What it does mean though is that if the US is growing slower, other countries are growing slower."

Obama wants to use a "balanced" mix of spending cuts and tax revenue increases achieved by closing loopholes used by the wealthy to cut the US deficit, and says he will not sign a bill that harms the middle class.

Republicans, who lost a previous showdown with Obama over raising tax rates for the rich, say the debate over hiking taxes is closed.

They say they are willing to close loopholes, but only in the context of a sweeping reform of the tax code, and maintain that Obama wants to use proceeds from any immediate revenue rises for more bloated government spending.

Hundreds of thousands of public employees and private contractors are threatened by the cuts.

Get lost in a stunning 320-gigapixel image of London

This zoomed-in image of the London Eye carousel -- which sits nearly 3 miles away from where the panorama was taken -- demonstrates the insane levels of magnification available at your fingertips.

British Telecommunications)

How well do you know the landmarks of London? Get up close and personal with a stunning 320-gigapixel image of the city captured atop the BT Tower.

Snapped by panorama experts 360Cities, the epic photography endeavor required the use of four Canon 7D dSLR cameras outfitted with some heavy-duty equipment.

Each camera used an EF 400mm f/2.8L IS II USM lens, Extender EF 2x III teleconverter, and a Rodeon VR Head ST robotic panorama head. After shooting 48,640 individual pictures over the course of three days (shortly after the 2012 Olympics), 360Cities spent the next several months assembling and stitching together the final gargantuan image.

To access the larger-than-life 360-degree panorama of London, simply click here or use the embedded panorama above. You can easily spot many familiars such as The Shard, London Eye, and Tower Bridge once you get moving.

You'll quickly notice that it's easy to clearly see nearly anything (or anyone) located many miles from the BT Tower. You almost feel like Big Brother after five minutes of looking. Pro tip: for maximum zoom, keep hitting the plus zoom button. Even if the slider bar indicates you've gone all the way you can actually go farther.

If printed out on paper, the 320-gigapixel super shot would stretch out 323 feet wide and stand 77 feet tall -- nearly the same size as Buckingham Palace. I wonder how much that frame would cost.

Businessman Dennis Tito Financing Manned Mission to Mars

Jane J. Lee

An announcement this week that a group led by the world's first space "tourist," Dennis Tito, plans to send a manned mission to flyby Mars in 2018 has lit up the Internet.

A press advisory from the new group, the Inspiration Mars Foundation, made no mention about whether there would be humans onboard.

But reports from NewSpace Journal say that there will be two crew members making the journey.

The Inspiration Mars Foundation, founded by Tito, plans to start its mission in January 2018, taking advantage of a rare launch window. Earth and Mars will be aligned in such a way that a trip that would normally take between two to three years would last about a year and a half, or 501 days.

The next such opportunity will occur in 2031, according to a Scientific American blog post.

Tito's foundation will hold a press conference on February 27 in Washington, presumably to offer more details about the trip.

The National Geographic Society is in talks with Inspiration Mars Foundation about a potential partnership around the 2018 mission.

The man behind the private Mars push is no stranger to the red planet.

In 2001 Tito paid $20 million to become the first "tourist" to rocket into space. He spent six days on the International Space Station. (Related: "7 Ways You Could Blast Off by 2023.")

Though Tito made his fortune in finance, he has a master's degree in engineering from Rensselaer Polytechnic Institute in New York and worked at NASA's Jet Propulsion Laboratory (JPL).

While at JPL, Tito worked on Mariner 4 and 9, which flew to the red planet in the 60s and 70s respectively. Mariner 4 was the first successful flyby of Mars in 1965, beaming back the first pictures of another planet from deep space. (Watch a video about exploring Mars.)

Jodi Arias' Friends Believe in Her Innocence

Accused murderer Jodi Arias believes she should be punished, but hopes she will not be sentenced to death, two of her closest friends told ABC News in an exclusive interview.

Ann Campbell and Donavan Bering have been a constant presence for Arias wth at least one of them sitting in the Phoenix, Ariz., courtroom along with Arias' family for almost every day of her murder trial. They befriended Arias after she first arrived in jail and believe in her innocence.

Arias admits killing her ex-boyfriend Travis Alexander and lying for nearly two years about it, but insists she killed Alexander in self defense. She could face the death penalty if convicted of murder.

Nevertheless, she is aware of the seriousness of her lies and deceitful behavior.

The women told ABC News that they understand that Arias needs to be punished and Arias understands that too.

"She does know that, you know, she does need to pay for the crime," Campbell said. "But I don't want her to die, and I know that she has so much to give back."

The lies that Arias admits she told to police and her family have been devastating to her, Bering said.

""She said to me, 'I wish I didn't have to have lied. That destroyed me,'" Donovan said earlier this week. "Because now when it's so important for her to be believed, she has that doubt. But as she told me on the phone yesterday, she goes, 'I have nothing to lose.' So all she can do is go out there and tell the truth."

During Arias' nine days on the stand she has described in detail the oral, anal and phone sex that she and Alexander allegedly engaged in, despite being Mormons and trying to practice chastity. She also spelled out in excruciating detail what she claimed was Alexander's growing demands for sex, loyalty and subservience along with an increasingly violent temper.

Besides her two friends, Arias' mother and sometimes her father have been sitting in the front row of the courtroom during the testimony. It's been humiliating, Bering said.

"She's horrified. There's not one ounce of her life that's not out there, that's not open to the public. She's ashamed," she said.

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.

Singapore trade expands 1.1% in 2012

SINGAPORE: Singapore's total external trade rose by 1.1 per cent in 2012, a contrast to the 8.0 per cent rise seen in the previous year.

The trade growth is lower than the previously projected range of between 3.0 and 4.0 per cent, said IE Singapore in its news release on Friday.

This, IE Singapore said, is due to poor trade performance in 4Q 2012.

Total trade reached S$984.9 billion in 2012, higher than the previous year's achievement of S$974.4 billion.

On a year-on-year basis, Singapore's total trade dropped by 2.9 per cent in 4Q 2012, following the previous quarter's decrease of 2.2 per cent due to decreases in both oil and non-oil trade.

Non-oil domestic exports (NODX) rose by 0.5 per cent in 2012, following the preceding year's increase of 2.2 per cent, due to higher shipments of non-electronic exports.

IE Singapore said the 0.5 per cent growth is lower than their projected 2012 growth of 2.0 to 3.0 per cent. This is due to a worse than expected NODX's performance in 4Q 2012.

Looking ahead, IE Singapore said projected total trade for 2013 is maintained at between 3.0 and 5.0 per cent while projected NODX growth for 2013 is kept at between 2.0 and 4.0 per cent.

Turbulence Ahead for Weather Satellites

Jane J. Lee

Like a celestial version of Pixar's industrious robot Wall-E, environmental-monitoring satellites continually whiz overhead, quietly performing their allotted tasks of taking data and beaming the information down to climate researchers and weather forecasters.

But a recent U.S. Government Accountability Office (GAO) report highlights the fact that this monitoring network—which weather forecasters and climate researchers rely on—is in trouble.

That's because these U.S.-owned satellites are aging, and there are serious concerns about whether their replacements will be ready by the time they start to break down, said J. Marshall Shepherd, president of the American Meteorological Society and a professor at the University of Georgia in Athens. (Read about the history of satellites.)

The replacement program, known as the Joint Polar Satellite System (JPSS), has suffered under ballooning budgets, mismanagement, and political wrangling. That's partly what prompted the GAO to put weather data on its list of government operations at high risk.

The report stated that "potential gaps in environmental-satellite data beginning as early as 2014 and lasting as long as 53 months have led to concerns that future weather forecasts and warnings—including warnings of extreme events such as hurricanes, storm surges, and floods—will be less accurate and timely."

"But even a 17-month gap, [the shortest estimate for a potential data gap], dramatically affects weather forecast ability, which could lead to challenges to protecting life and property," Shepherd said.

If European models of superstorm Sandy—well known for their accuracy in predicting the monster storm's path—hadn't had information from polar-orbiting satellites, for instance, they would've shown Sandy staying harmlessly out to sea rather than turning inland toward New York and New Jersey. (Read about "Weather Gone Wild" in the September 2012 issue of National Geographic magazine.)

Basic research would also suffer from the loss of data, said Scott Rayder, senior adviser to the president of the University Corporation for Atmospheric Research. "Long-term weather data is climate data, so these [satellite] sensors are important in figuring out how the atmosphere works."

Cause for Concern

Information forecasters incorporate into their models comes from two sets of satellites run by the U.S. National Oceanic and Atmospheric Administration (NOAA) and NASA—geostationary satellites and polar-orbiting satellites, the American Meteorological Society's Shepherd explained.

Onboard instruments measure environmental factors including atmospheric moisture, sea surface temperature, and atmospheric ozone. This helps scientists keep tabs on things like precipitation and the health of the planet's ozone layer.

The current concern is focused on replacements for polar-orbiting satellites.

Traveling 517 miles (833 kilometers) above the Earth in a pole-to-pole direction every 90 minutes, NOAA's current crop of Polar Operational Environmental Satellites (POES) are nearing the twilight of their life cycles, Shepherd said.

The POES satellites were built with a two- to three-year operational lifetime in mind, said James Gleason, of NASA's Goddard Spaceflight Center in Maryland.

"And they've lasted a long time, some [for] more than a decade," he said. The most recent POES satellite, NOAA-19, was launched in 2009.

Dire Situation

NOAA has another polar-orbiting satellite, called Suomi NPP, that's also taking weather data. Launched in 2011, it was supposed to be a proof of concept in order to test instruments slated to fly on JPSS, said Shepherd.

But due to repeated delays in the JPSS program, NOAA is using Suomi NPP as an operational satellite. "It's working swimmingly," he said.

"We're pretty sure [Suomi] NPP will last until 2016," said NASA's Gleason, senior project scientist for JPSS.

But JPSS isn't scheduled to launch until early 2017—and that depends on what happens to funding in the federal budget and whether the sequester kicks in, Gleason said.

NOAA is currently working on a plan to bridge any gap, should it occur, in data from their satellites. One possibility includes using a fleet of satellites owned by the U.S. military, called the Defense Meteorological Satellite Program, to gather needed weather data.

The agency put out a call last year asking for suggestions on how the community could deal with a gap.

But as it stands right now, the situation is dire, said Shepherd.

Las Vegas Shooting Launches Multi-State Manhunt

An argument in the valet area of a Las Vegas hotel led to a deadly drive-by shooting on the occupants of a Maserati on Vegas' glitzy strip, initiating a multi-state manhunt for the black Range Rover from which the shots were fired.

Three people were left dead in the attack, including two who died when their taxi was struck by the careening sports car and exploded into flames.

"What happened is not just tragic, but underscores the level of violence we see sometimes here in Las Vegas as well as across America," Las Vegas Metropolitan Sheriff Doug Gillespie said at a news conference today. "Clearly, the suspects in this shooting have no regard for the lives and safety of others."

The altercation took place in the valet area of the Aria resort and casino. Gillespie said there is currently "no indication" what the squabble was about.

Gillespie said that authorities do not know how many people are in the SUV, but that they are considered armed and dangerous. He warned members of the public to stay away from it.

"You should not take action," he said. "Instead, call your local police department and alert them to the whereabouts of the suspect vehicle."

Authorities in Nevada, Utah, Arizona and California are all on alert for the car.

"These individuals will be found," Gillespie said. "They will be prosecuted to the full extent of the law."

The Range Rover SUV shot at two people in the Maserati, which caused a multi-car crash. Police have not released the model of the Maserati, but the price of a new Maserati ranges from $123,000 to $142,000.

Police said that they believe a group of men riding in a black Range Rover Sport SUV pulled up alongside the Maserati around 4:20 a.m. today and fired shots into the car, striking the driver and passenger, according to Officer Jose Hernandez of the Las Vegas Metropolitan police department.

The Maserati then swerved through an intersection, hitting at least four other cars. One car that was struck, a taxi with a driver and passenger in it, caught on fire and burst into flames, trapping both occupants, Hernandez said.

The SUV then fled the scene, according to cops.

Gillespie said investigators are in the process of gathering video footage from hotels, casinos and the taxi cabs that were at the intersection.

The driver of the Maserati died from his gunshot wounds at University Medical Center shortly after the shooting, according to Sgt. John Sheahan.

The driver and passenger of the taxi both died in the car fire.

At least three individuals, including the passenger of the Maserati, were injured during the shooting and car crashes and taken to UMC hospital for treatment.

Authorities said the Maserati passenger, identified only as a man, sustained only a minor injury to his arm. He is speaking to and cooperating with police.

They do not yet know whether the cars had local plates or were from out of state.

No bystanders were hit by gunfire, Hernandez said.

"We're currently looking for a black Range Rover Sport, with large black rims and some sort of dealership advertising or advertisement plates," Hernandez said. "This is an armed and dangerous vehicle."

The Las Vegas Convention and Visitors Authority had no immediate comment about the safety of tourists in the wake of the shooting today.

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.

Qantas reports sharp rise in first-half profits

SYDNEY: Australian flag carrier Qantas on Thursday reported that first-half net profit more than doubled to A$111 million (US$114 million), also announcing an upgrade to its fleet.

The result in the six months to December 31 was up 164 percent on the same period in the previous year and in line with guidance, "despite challenging conditions in international and domestic air travel markets."

Underlying profit before tax -- the airline's preferred measure of financial performance -- was A$223 million, up 10 percent.

Qantas also announced an order for five new Boeing 737-800s and the upgrade of 20 Airbus A330-200s and 10 A330-300s.

The additional Boeing 737-800 aircraft are for the flag carrier's domestic service and for delivery during 2014, the company said in a statement, adding that leases on two existing B737-800s would be extended this year.

"The refurbished aircraft will give Qantas International a truly world-class product in global aviation's most dynamic and competitive market," chief executive Alan Joyce told a press conference.

"Growing with Asia is a major priority for the Qantas Group and this investment underpins our commitment to the region."

Joyce said: "Older narrow body Boeing 737-400s will be phased out by the end of 2013 and Boeing 767s by mid-2015.

"We are simplifying our fleet and making better use of the greater flexibility and higher frequencies that the B737-800s provide, while investing in what will be the best domestic onboard product anywhere in the world with the A330s."

The A330 reconfigurations and new orders will not affect planned capital expenditure of A$1.6 billion in 2012/13 and A$1.5 billion in 2013/14.

However, Qantas International reported an underlying before-tax loss of A$91 million in the six-month period, an improvement of A$171 million.

"Qantas International is well advanced in its turnaround plan," Joyce said.

"The 65 per cent improvement in Qantas International's underlying EBIT is testament to the steps taken to remove cost from the businesses, from closing down loss-making routes to retiring aircraft and consolidating operations."

Qantas is planning to broaden its reach in Asia as part of a strategy to turn around its struggling international arm.

The move is a consequence of its global alliance with Dubai-based Emirates, which means services to Asia will no longer be tied to onward links to Europe.

New direct destinations from Australia being considered include Beijing, Seoul, Mumbai, Delhi and Tokyo-Haneda at the same time as increasing capacity and frequency of flights to Hong Kong and Singapore.

Australia's competition watchdog last month gave Qantas and Emirates permission to launch their alliance in which the airlines will coordinate ticket prices and flight schedules.

Qantas will shift its hub for European flights to Dubai from Singapore and end a partnership with British Airways. The tie-up is seen as vital to the sustainability of Qantas, which last year posted its first annual deficit since privatisation in 1995 due to tough regional competition and high fuel costs.

Sony pushes streaming and sharing with PS4

Sony's new PlayStation 4 will focus on streaming games across a network of devices and tapping into social gaming, executives said today.

This means faster downloading times, video clip share buttons, and the ability to take over a friend's controller when they are in need of assistance, the company highlighted at its event in New York today.

Mark Cerny, the lead system architect for
PS4, said the console system's OnLive network will have a seamless upload experience. This means players can start playing the first part of a game before it is done downloading.

Additionally, PS4 boasts integration third party and services, phones, and
tablets -- you'll be able to use your smartphone to view gameplay videos and challenge friends.

Along with Cerny's announcement, Sony featured cloud-gaming firm Gaikai's contributions to PS4. Gaikai CEO Dave Perry said your friends will be able to virtually look over your shoulder and interact with you as you play, as well as post comments on their screens.

He said the network will actually learn from your behavior and give you a better experience.

"The PlayStation network will get to know you by understanding your preferences and the preferences of your community," he said.

The True Story of History's Only Known Meteorite Victim

The Russian meteorite, whose sonic boom damaged buildings and injured more than a thousand last week, is not the first to shatter a human life. (See pictures: "Meteorite Hits Russia.")

Take the true story of Ann Hodges, the only confirmed person in history to have been hit by a meteorite.

On a clear afternoon in Sylacauga, Alabama (see map), in late November 1954, Ann was napping on her couch, covered by quilts, when a softball-size hunk of black rock broke through the ceiling, bounced off a radio, and hit her in the thigh, leaving a pineapple-shaped bruise.

Ann's story is particularly rare because most meteorites usually fall into the ocean or strike one of Earth's vast, remote places, according to Michael Reynolds, a Florida State College astronomer and author of the book Falling Stars: A Guide to Meteors & Meteorites.

"Think of how many people have lived throughout human history," Reynolds said.

"You have a better chance of getting hit by a tornado and a bolt of lightning and a hurricane all at the same time."

Out of This World

Before the meteorite slammed into Ann's living room, people in tiny Sylacauga and across eastern Alabama had reported seeing "a bright reddish light like a Roman candle trailing smoke," according to the web publication "The Day the Meteorite Fell in Sylacauga," which was produced by the Alabama Museum of Natural History in 2010.

Others saw "a fireball, like a gigantic welding arc," accompanied by tremendous explosions and a brown cloud. (See video: "Predicting Meteorite Impacts.")

A government geologist working in a nearby quarry was called to the scene and determined the object was a meteorite, but not everyone in town was so sure, according to the museum publication. Many thought a plane had crashed—others suspected the Soviets.

So many people flocked to Hodges's house that when her husband Eugene Hodges, a utility worker, returned home from work, he had to push gawkers off the porch to get inside.

Ann was so overwhelmed by the crowd that she was transferred to a hospital. With Cold War paranoia running high, the Sylacauga police chief confiscated the black rock and turned it over to the Air Force.

After the Air Force confirmed it was a meteorite, the question then was what to do with it. The public demanded the space rock be returned to Ann, and she agreed.

"I feel like the meteorite is mine," she said, according to the museum. "I think God intended it for me. After all, it hit me!"

Simple Country People

But there was a hitch. Ann and Eugene were renters, and their landlady, a recently widowed woman named Birdie Guy, wanted the meteorite for herself.

Guy obtained a lawyer and sued, claiming the rock was hers since it had fallen on her property. The law was actually on her side, but public opinion wasn't.

Guy settled out of court, giving up her claim to the meteorite in exchange for $500. Eugene was convinced the couple could make big money off the rock and turned down a modest offer from the Smithsonian.

But no one bit, and so the Hodges donated the meteorite to the natural history museum in 1956, where it's still on display. (Related: "Meteorites: Best Places to See Them Up Close.")

Ann later suffered a nervous breakdown, and in 1964 she and Eugene separated. She died in 1972 at 52 of kidney failure at a Sylacaugan nursing home.

Eugene suspects the meteorite and frenzy that followed had taken its toll on Ann. He said "she never did recover," according to the museum.

Ann "wasn't a person who sought out the limelight," added museum director Randy Mecredy. "The Hodges were just simple country people, and I really think that all the attention was her downfall."

Armstrong Snubs Offer From Anti-Doping Officials

Lance Armstrong has turned down what may be his last chance at reducing his lifetime sporting ban.

Armstrong has already admitted in an interview with Oprah Winfrey to a career fueled by doping and deceit. But to get a break from the U.S. Anti-Doping Agency, all he had to do was tell his story to those who police sports doping. The deadline was today, and Armstrong now says he won't do it.

"For several reasons, Lance will not participate in USADA's efforts to selectively conduct American prosecutions that only demonize selected individuals while failing to address the 95 percent of the sport over which USADA has no jurisdiction," said Tim Herman, Armstrong's longtime lawyer. "Lance is willing to cooperate fully and has been very clear: He will be the first man through the door, and once inside will answer every question, at an international tribunal formed to comprehensively address pro cycling."

But the "international tribunal" Armstrong is anxious to cooperate with has one major problem: It doesn't exist.

The UCI, cycling's governing body, has talked about forming a "truth and reconciliation" commission, but the World Anti-Doping Agency has resisted, citing serious concerns about the UCI and its leadership.

READ MORE: Lance Armstrong May Have Lied to Winfrey: Investigators

WATCH: Armstrong's Many Denials Caught on Tape

U.S. Anti-Doping Agency officials seemed stunned by Armstrong's decision simply to walk away.

"Over the last few weeks, he [Armstrong] has led us to believe that he wanted to come in and assist USADA, but was worried of potential criminal and civil liability if he did so," said Travis Tygart, CEO of the U.S. Anti-Doping Agency. "Today, we learned from the media that Mr. Armstrong is choosing not to come in and be truthful and that he will not take the opportunity to work toward righting his wrongs in sport."

Armstrong's ongoing saga plays out amid a backdrop of serious legal problems.

Sources believe one reason Armstrong wants to testify to an international tribunal, rather than USADA, is because perjury charges don't apply if Armstrong lies to a foreign agency, they told ABC News.

While Armstrong has admitted doping, he has not given up any details, including the people and methods required to pull off one of the greatest scandals in all of sport.

Armstrong is facing several multimillion-dollar lawsuits right now, but his biggest problems may be on the horizon. As ABC News first reported, a high-level source said a criminal investigation is ongoing. And the Department of Justice also reportedly is considering joining a whistleblower lawsuit claiming the U.S. Postal Service was defrauded out of millions of dollars paid to sponsor Armstrong's cycling team.

Football: LionsXII impress Fandi in 2-2 draw with Johor

SINGAPORE: Fandi Ahmad was left shocked and impressed after his star-studded Johor Darul Takzim were forced to share the spoils at a packed Larkin Stadium, as they drew 2-2 with an impressive LionsXII side in the Malaysian Super League (MSL) on Tuesday night.

Fandi told reporters after the match that he and his players were shocked that the LionsXII had opted to go on the offensive from the start, saying that he had expected V Sundramoorthy's side to adopt "a more counterattacking strategy".

"This has been the best I've seen the LionsXII play," praised Fandi. "I'm also quite puzzled why my players couldn't rise to the occasion tonight and perform."

Indeed, there was a very different look to the LionsXII on Tuesday as they refused to sit back in the first half and often pressed forward in numbers in search of goals.

The LionsXII hardly looked in awe of Johor - who boast the likes of former Lazio player Simone Del Nero and former Spanish international Daniel Guiza - and impressed with fluid passing and hard tackling.

Their desire to draw first blood did not take long to pay dividends when Hariss Harun - who was playing his first match since he suffered a broken fibula in November - blasted the visitors into the lead after four minutes.

The Larkin Stadium was thoroughly silenced by the midfield lynchpin, but it was only for a moment.

Just six minutes later, Johor's livewire midfielder Nurul Azwan lost his marker and sent a low cross into the area which Del Nero superbly headed past goalkeeper Izwan Mahbud to score his first club goal.

Eager to reclaim the initiative, Sundram's charges continued to attack and were rewarded in the 37th minute when Baihakki Khaizan scored with a spectacular diving header following a free-kick.

The match continued to be played at a frenetic pace even after the restart and Fandi soon brought on even more firepower in Safee Sali.

With Safee, Guiza and Norshahrul Idlan Talaha now in attack, the LionsXII found themselves pegged back and digging deep to defend.

Fandi's decision to overload the attack eventually paid off as Norshahrul shrugged off tired LionsXII defenders and fired home Johor's equaliser from 20 yards out.

Despite not bagging the win, Sundram was satisfied with the result, praising his players for the tenacity they displayed.

He said: "I'm very happy the players fought for every ball tonight. The MSL is a very physical league and we've got to be able to fight hard on the field. Player to player, I'm very pleased that our boys can compete against Fandi's."

uBiome project to sequence the bacteria that live on us

Researchers will be testing swabs taken from thousands of paying volunteers.

(Credit:
uBiome Project)

Oxford University Ph.D. student Jessica Richman, who today finished raising some $350,000 from more than 2,500 people wanting to take part in the uBiome project, isn't shying away from reality: "Yes, we are going to be sampling people's poo," she told the Guardian this week.

And for the squeamish, she offered an asterisk: "You'll only have to wipe it on the toilet paper."

The uBiome project is a "citizen science" effort to sequence the genomes of the trillions of bacteria that colonize our bodies and likely play pivotal roles, both good and bad, in our health.

By sequencing the bacteria of volunteers (provided via Q-tips swabs of mouths, noses, ears, genitals, and guts) at a lab at the University of California in San Francisco, and then having volunteers log into a Web site to complete health surveys, Richman and her team hope to eventually understand what causes a range of health issues, from breast cancer and Crohn's to dementia and chronic obstructive pulmonary disease.

The uBiome project has far surpassed its original $100,000 goal (deadline was this morning). Apparently plenty of people are not afraid to sample their own feces.

And it turns out that sequencing the many strains of bacteria that live in and on our bodies -- known as the "microbiome" -- may be every bit as complicated as sequencing the human genome; after all, microbes outnumber human cells 10 to 1, according to the researchers.

The results may provide a good deal of information about the roots of various health issues given that "about 30 percent of the small molecules found in the blood come from the microbiome," Richman said. "So it certainly looks like some of the illnesses we see are linked to it."

Various studies are implicating specific strains of bacteria in a range of health outcomes, both good and bad. The science gets extremely complex, though, because the bacteria do not live in a vacuum and are interacting with other bacteria all the time.

Richman, who calls this "exploratory science," does not shy away from the challenge and hopes to discover correlations between bacteria strains and health outcomes to better understand both health and disease.

Meanwhile, volunteers who have paid into the project have the option to not only access details gleaned from their own, er, swabs, but to share that data if they choose. "Your data is yours -- you can download it, share it, do whatever you want with it," the team writes on its funding site. "We encourage you to opt-in to share your data with our scientists, but we respect your privacy and will not force you to do so. The data is also anonymized and private."

As for whom the researchers hoped would volunteer:

Everyone! skinny, fat, sick, healthy, Coke, Pepsi, Barack Obama, Mitt Romney, babies, grandmothers, lactose intolerant, gluten allergic, happy, sad, smoker, drinker, bald, vegan, smelly, bad breath, brown hair, blue eyes, blue hair, brown eyes, Atkins diet, high carb diet, sleepy, gassy, anxious, horny, asexual, smart, dyslexic, gorgeous, pregnant, and completely average. Babies, older people, women, men...everyone!

New Study Analyzes Heavy Metal Dancing

Parents may never understand their rock 'n' roll loving children, but scientists might. A study published online in arXiv this week seeks to explain the "mosh pit"—using physics.

To most scientists, heavy metal refers to elements on the lower end of the periodic table. But to Jesse Silverberg and Matt Bierbaum, doctoral students at Cornell University's department of Condensed Matter Physics, the aggressive music—and the violent dancing that accompanies it—could be a key to understanding extreme situations such as riots and panicked responses to disasters.

For the past two years, Silverberg and Bierbaum have studied "moshing," at heavy metal concerts, using theories of collective motion and the physical properties of gasses to better understand the chaos of metal fans' dancing.

Moshing, for those who have never attended a heavy metal show, is a form of dancing in which participants bump, jostle, and slam into one another. It's a form of social ritual that anthropologists have likened to spirit possession in its uncontrolled, dynamic, and often violent nature.

Silverberg and Bierbaum say it can also be understood by applying models of gaseous particles. As these particles float in groups, they too run, bash, and slam into each other, sending the elements flying in chaotic patterns.

"We are interested in how humans behave in similar excited states," said Silverberg, "but it's not exactly ethical to start a riot for research."

Extreme Physics

Mosh pits provided the scientists with a way to observe excited collective movement without causing undue injury or death. Analyzing hours of recorded footage from concerts and making multiple field trips to music clubs, Silverberg and Bierbaum recognized the particulate physical patterns in the mosh pit.

Further, they differentiated two distinct forms of heavy metal dancing: the "mosh pit" itself, which follows the gaseous pattern, and the "circle pit" (where dancers run, smash, and dance in a circular rotation) within it, which adheres to a vortex pattern of particulate behavior.

Based on these observations, they created an interactive computer model depicting the behavior.

Animal Instincts

"Herd animals behave in very similar spirit—what physicists call 'flocking' behavior," said Bierbaum. (See "The Genius of Swarms," from the July 2007 issue of National Geographic magazine.)

As with groups of flying birds or schooling fish, simple rules can be applied to individuals in large groups—like moshers—to understand what seems to be very complex behavior. This makes modeling possible, allowing computers to re-create immense numbers of actions in a matter of seconds. These models can then be used to design spaces that would minimize trampling or injury, or to tailor responses to disasters like fires.

"The lessons we've learned in mosh pits [could be used] to build better stadiums, or movie theaters," Silverberg said.

James Sethna, one of the researchers' advising professors, hastened to add that his students' forays into heavy metal science "didn't start out for reasons of creating safer stadiums. We did it because it was cool and we wanted to know if we could explain human behavior—albeit slightly intoxicated behavior—without having to use complex [models]."

A longtime heavy metal fan himself, Silverberg shared which band produced the best results: "Killswitch Engage ... always gets the crowd nuts. Although of course everyone has their own favorites."

Report Fingers Chinese Military Unit in US Hacks

A Virginia-based cyber security firm has released a new report alleging a specific Chinese military unit is likely behind one of the largest cyber espionage and attack campaigns aimed at American infrastructure and corporations.

In the report, released today by Mandiant, China's Unit 61398 is blamed for stealing "hundreds of terabytes of data from at least 141 organizations" since 2006, including 115 targets in the U.S. Twenty different industrial sectors were targeted in the attacks, Mandiant said, from energy and aerospace to transportation and financial institutions.

Mandiant believes it has tracked Unit 61398 to a 12-story office building in Shanghai that could employ hundreds of workers.

"Once [Unit 61398] has established access [to a target network], they periodically revisit the victim's network over several months or years and steal broad categories of intellectual property, including technology blueprints, proprietary manufacturing processes, test results, business plans, pricing documents, partnership agreements, and emails and contact lists from victim organizations' leadership," the report says.

The New York Times, which first reported on the Mandiant paper Monday, said digital forensic evidence presented by Mandiant pointing to the 12-story Shangai building as the likely source of the attacks has been confirmed by American intelligence officials. Mandiant was the firm that The Times said helped them investigate and eventually repel cyber attacks on their own systems in China last month.

The Chinese government has repeatedly denied involvement in cyber intrusions and Chinese Foreign Ministry spokesperson Hong Lei said today that the claims in the Mandiant report were unsupported, according to a report by The Associated Press.

"To make groundless accusations based on some rough material is neither responsible nor professional," he reportedly said.

Mandiant's report was released a week after President Obama said in his State of the Union address that America must "face the rapidly growing threat from cyber attack."

"We know hackers steal people's identities and infiltrate private e-mail. We know foreign countries and companies swipe our corporate secrets. Now our enemies are also seeking the ability to sabotage our power grid, our financial institutions, and our air traffic control systems. We cannot look back years from now and wonder why we did nothing in the face of real threats to our security and our economy," he said.

Though Obama did not reference China or any country specifically, U.S. officials have previously accused the Asian nation of undertaking a widespread cyber espionage campaign.

Referring to alleged Chinese hacking in October 2011, House Intelligence Committee Chairman Rep. Mike Rogers (R-Mich.) said in an open committee meeting that he did not believe "that there is a precedent in history for such a massive and sustained intelligence effort by a government agency to blatantly steal commercial data and intellectual property."

Rogers said that cyber intrusions into American and other Western corporations by hackers working on behalf of Beijing -- allegedly including attacks on corporate giants like Google and Lockheed Martin -- amounted to "brazen and widespread theft."

"The Chinese have proven very, very good at hacking their way into very large American companies that spend a lot of money trying to protect themselves," cyber security expert and ABC News consultant Richard Clarke said in an interview last week.

Biofuel rush is wiping out unique American grasslands

Say goodbye to the grass. The scramble for biofuels is rapidly killing off unique grasslands and pastures in the central US.

Christopher Wright and Michael Wimberly of South Dakota State University in Brookings analysed satellite images of five states in the western corn belt. They found that 530,000 hectares of grassland disappeared under blankets of maize and soya beans between 2006 and 2011. The rate was fastest in South Dakota and Iowa, with as much as 5 per cent of pasture becoming cropland each year.

The trend is being driven by rising demand for the crops, partly through incentives to use them as fuels instead of food.

The switch from meadows to crops is causing a crash in populations of ground-nesting birds. One of the US's most important breeding grounds for wildfowl, an area called the Prairie Pothole Region, is also at risk, with South Dakota's crop fields now within 100 metres of the wetlands. "Half of North American ducks breed here," says Wright.

Bill Henwood of the Temperate Grasslands Conservation Initiative in Vancouver, Canada, says the results are distressing. "Exchanging real environmental impacts for the dubious benefits of biofuels is counterproductive," he says. "Last year's record drought in the corn belt all but wiped out the crops anyway."

Greater US military role in Mali likely after polls: senator

BAMAKO: The United States is likely to play a more active military role in Mali, where French-led forces are battling Islamist rebels, after the country holds elections, the chair of a key Senate sub-committee said Monday.

Washington has been providing intelligence, transport and mid-air refuelling to France, which launched its intervention last month, but cannot work directly with the Malian army until a democratically elected government replaces current leaders who came to power after a coup, said Christopher Coons, chair of the Senate foreign relations committee's Africa sub-committee.

"There is the hope that there will be additional support from the United States in these and other areas, but ... American law prohibits direct assistance to the Malian military following the coup," Coons told journalists in the Malian capital.

"After there is a full restoration of democracy, I would think it is likely that we will renew our direct support for the Malian military," added the senator, who led a bipartisan congressional delegation to Mali to meet with interim president Dioncounda Traore and French and African defence officials.

US military aid to Mali before the March 2012 coup consisted largely of training and equipment such as vehicles, a State Department official said.

But military assistance "would obviously be resumed in a way commensurate with the current needs. Priorities would have shifted a bit," the official added.

"There could be other kinds of assistance that had there not been a coup we could have provided, or requests for things now that we can't provide."

Some US lawmakers criticised President Barack Obama's administration last week for not doing more to help France in Mali.

"This is a NATO ally fighting Al-Qaeda-linked terrorists -- it shouldn't be that hard," said House foreign affairs committee chairman Ed Royce.

The hint of greater US involvement after elections adds to the complicated calculus of picking a date for the polls.

Traore, the interim president, has said he wants elections by July 31.

But critics say that is too soon given the problems Mali still faces, including ongoing insurgent attacks, a deeply divided military and hundreds of thousands of people who have fled their homes.

The minister responsible for organising the elections, Territorial Administration Minister Moussa Sinko Coulibaly, said last week the timeline "can be changed if necessary".

France, which launched its intervention on January 11 as Al-Qaeda-linked groups that had occupied the north for 10 months made incursions into government territory, is keen to share the military burden in Mali, and has announced plans to start bringing its 4,000 troops home in March.

The European Union formally approved a military training mission Monday that will be tasked with getting Mali's under-funded army ready to secure reclaimed territory.

But France is the only Western country with combat troops on the ground, and would like to hand over to some 6,000 west African troops who are slowly being deployed to help.

Mali imploded after a coup by soldiers who blamed the government for the army's humiliation at the hands of separatist rebels in the north.

With the capital in disarray, Al-Qaeda-linked fighters hijacked the independence rebellion and took control of a territory larger than Texas.

Ubuntu just went 1080p on Dell's sleekest laptop.

The 2.99-pound XPS 13 Developer Edition laptop is now available on Dell's site for $1,549.

Those specifications, with the critical exception of the Ubuntu Linux, are identical to the 1080p XPS 13 for
Windows 8.

Here are the specs:

• Operating system: Ubuntu Linux 12.04 LTS
  
• Display: 13.3-inch 1,920x1,080 panel
  
• Processor: 3rd Generation Intel Core i7-3537U
  
• Memory: 8GB2 DDR3 SDRAM at 1600MHz
  
• Storage: 256GB solid-state drive
  
• Graphics: Intel HD 4000
  
• Price: $1,549
  

In addition to the U.S., Dell will also start to roll it out in select countries in Europe, including the UK, France, Germany, Austria, Belgium, Denmark, and Finland.

The XPS 13 is one of the better ultrabook designs to emerge from a top-tier PC vendor. It squeezes a 13.3-inch screen into a footprint more typical of 12-inch laptops, boasts Gorilla Glass, and is constructed from aluminum and carbon fiber, allowing Dell to keep the weight to just under three pounds.

The upgraded display is also brighter and has wider viewing angles that the original 1,366x768 XPS 13 model.

Confirmed: Dogs Sneak Food When People Aren't Looking

Many dog owners will swear their pups are up to something when out of view of watchful eyes. Shoes go missing, couches have mysterious teeth marks, and food disappears. They seem to disregard the word "no."

Now, a new study suggests dogs might understand people even better than we thought. (Related: "Animal Minds.")

The research shows that domestic dogs, when told not to snatch a piece of food, are more likely to disobey the command in a dark room than in a lit room.

This suggests that man's best friend is capable of understanding a human's point of view, said study leader Juliane Kaminski, a psychologist at the U.K.'s University of Portmouth.

"The one thing we can say is that dogs really have specialized skills in reading human communication," she said. "This is special in dogs." (Read "How to Build a Dog.")

Sneaky Canines

Kaminski and colleagues recruited 84 dogs, all of which were more than a year old, motivated by food, and comfortable with both strangers and dark rooms.

The team then set up experiments in which a person commanded a dog not to take a piece of food on the floor and repeated the commands in a room with different lighting scenarios ranging from fully lit to fully dark.

They found that the dogs were four times as likely to steal the food—and steal it more quickly—when the room was dark. (Take our dog quiz.)

"We were thinking what affected the dog was whether they saw the human, but seeing the human or not didn't affect the behavior," said Kaminski, whose study was published recently in the journal Animal Cognition.

Instead, she said, the dog's behavior depended on whether the food was in the light or not, suggesting that the dog made its decision based on whether the human could see them approaching the food.

"In a general sense, [Kaminski] and other researchers are interested in whether the dog has a theory of mind," said Alexandra Horowitz, head of the Dog Cognition Lab at Barnard University, who was not involved in the new study.

Something that all normal adult humans have, theory of mind is "an understanding that others have different perspective, knowledge, feelings than we do," said Horowitz, also the author of Inside of a Dog.

Smarter Than We Think

While research has previously been focused on our closer relatives—chimpanzees and bonobos—interest in dog cognition is increasing, thanks in part to owners wanting to know what their dogs are thinking. (Pictures: How smart are these animals?)

"The study of dog cognition suddenly began about 15 years ago," Horowitz said.

Part of the reason for that, said Brian Hare, director of the Duke Canine Cognition Lab and author of The Genius of Dogs, is that "science thought dogs were unremarkable."

But "dogs have a genius—years ago we didn't know what that was," said Hare, who was not involved in the new research. (See pictures of the the evolution of dogs, from wolf to woof.)

Many of the new dog studies are variations on research done with chimpanzees, bonobos, and even young children. Animal-cognition researchers are looking into dogs' ability to imitate, solve problems, or navigate social environments.

So just how much does your dog understand? It's much more than you—and science—probably thought.

Selectively bred as companions for thousands of years, dogs are especially attuned to human emotions—and, study leader Kaminski said, are better at reading human cues than even our closest mammalian relatives.

"There has been a physiological change in dogs because of domestication," Duke's Hare added. "Dogs want to bond with us in ways other species don't." (Related: "Dogs' Brains Reorganized by Breeding.")

While research reveals more and more insight into the minds of our furry best friends, Kaminski said, "We still don't know just how smart they are."
