Get cirrus in the fight against climate change



































FEATHERY cirrus clouds are beautiful, but when it comes to climate change, they are the enemy. Found at high-altitude and made of small ice crystals, they trap heat - so more cirrus means a warmer world. Now it seems that, by destroying cirrus, we could reverse all the warming Earth has experienced so far.












In 2009, David Mitchell of the Desert Research Institute in Reno, Nevada, proposed a radical way to stop climate change: get rid of some cirrus. Now Trude Storelvmo of Yale University and colleagues have used a climate model to test the idea.












Storelvmo added powdered bismuth triiodide into the model's troposphere, the layer of the atmosphere in which these clouds form. Ice crystals grew around these particles and expanded, eventually falling out of the sky, reducing cirrus coverage. Without the particles, the ice crystals remained small and stayed up high for longer.












The technique, done on a global scale, created a powerful cooling effect, enough to counteract the 0.8 °C of warming caused by all the greenhouse gases released by humans (Geophysical Research Letters, DOI: 10.1002/grl.50122).


















But too much bismuth triiodide made the ice crystals shrink, so cirrus clouds lasted longer. "If you get the concentrations wrong, you could get the opposite of what you want," says Storelvmo. And, like other schemes for geoengineering, side effects are likely - changes in the jet stream, say.












Different model assumptions give different "safe" amounts of bismuth triiodide, says Tim Lenton of the University of Exeter, UK. "Do we really know the system well enough to be confident of being in the safe zone?" he asks. "You wouldn't want to touch this until you knew."












Mitchell says seeding would take 140 tonnes of bismuth triiodide every year, which by itself would cost $19 million.

Latin America, Europe back free trade






SANTIAGO: European and Latin American leaders pledged here Saturday to shun protectionism and boost their strategic partnership to foster free trade.

Some 60 countries are represented at the summit between the 27-member European Union and the Community of Latin American and Caribbean States (CELAC).

Set up in Caracas in December 2011 at the behest of Venezuela, CELAC groups all nations from across the Americas except the United States and Canada and aims to boost regional trade and integration.

Chilean President Sebastian Pinera, the two-day summit's host, opened the session with a call for a new "strategic alliance to achieve sustainable development."

And indeed participants unanimously adopted a summit statement extolling their "strategic partnership to achieve sustainable development."

They also reiterated their commitment "to avoid protectionism in all its forms" and to "favour an open and non-discriminatory, ruled-based multilateral trade system."

"We firmly reject all coercive measures of unilateral character with extra-territorial effect that are contrary to international law and the commonly accepted rules of free trade," the statement said.

The leaders also pledged to continue working together "toward a new international financial architecture."

And they backed concrete actions to bolster law enforcement cooperation "to dismantle criminal organizations, all within the full respect of human rights and international law."

There was also support for the convening of a special UN General Assembly session on the global drug problem.

The leaders also gave a nod to "the universality and indivisibility of human rights as laid out in the Universal Declaration of Human Rights."

It was the seventh summit between the two blocs but the first since the creation of CELAC. The two sides agreed to hold the next EU-CELAC summit in Brussels in 2015.

The EU is the biggest outside investor in Latin America, accounting for three percent of direct foreign investment in CELAC or $385 billion in 2010.

EU officials noted that the figure exceeds the combined investment in China, Russia and India.

"We need a strong political commitment to rein in protectionism and promote liberalization," European Commission President Jose Manuel Barroso told a meeting of business chiefs leaders shortly before the political summit's opening.

Powerful German Chancellor Angela Merkel, whom the Chilean press has dubbed "Europe's boss," called for "cooperation without barriers to trade."

"The dynamic development of this entire region shows that we, within the EU, must strive to ensure we are not left behind, to improve our competitiveness, reduce our debt. We cannot live on the backs of future generations," she added.

The Europeans are particularly keen on securing the speedy conclusion of a free trade pact between the EU and the South American trading bloc Mercosur.

Negotiations have so far stumbled over differences on agriculture -- notably Europe's subsidies to its farmers, which undermine Latin America's efforts to sell its own products.

Argentine President Cristina Kirchner, who has taken some protectionist measures, said that the EU-Mercosur negotiations, launched in 2004, must restart on a "new basis" that can clear the way for a deal.

"The negotiations with the EU cannot be based on decisions made in 2004. We need new premises, first among all Mercosur members, not just between Brazil and Argentina," she said after a bilateral session with Rousseff.

Kirchner suggested establishing an ad hoc Mercosur panel to come up with new proposals and make a new offer to the EU later this year.

Meanwhile, a Venezuelan minister said here that President Hugo Chavez has beaten a severe respiratory infection that occurred after his latest cancer surgery in Cuba.

"The respiratory infection has been overcome, although there still is some degree of breathing difficulty that is being treated appropriately," Communications Minister Ernesto Villegas said on the sidelines of a EU-CELAC summit.

Chavez, who had surgery on December 12, has not been seen in public since he left Caracas for surgery at a hospital in Cuba.

Monday, the 33 CELAC leaders will hold their own summit here, with Cuba taking over chairmanship from Chile for one year. They are hoping to overcome ideological and economic differences to foster greater regional integration.

The meeting will seal Cuba's full regional reintegration and mark a major diplomatic coup for 81-year-old President Raul Castro. Cuba, the only non-democratic Communist-ruled country in the Americas, has been under a US economic embargo since 1962.

The ultimate gall of a heartless iPhone thief



An object of desire?



(Credit:
CNET)


One should never expect justice in life.


The best one can hope for is poetry.


And yet, just once or twice, both manage to collide with a deliciousness that moves the soul.


Here is the tale of a teenage girl who had her iPhone stolen.



As The New York Times composes it, the girl had her
iPhone 4S ripped from her by a teenage boy in Brooklyn's notoriously difficult Prospect Park.


iPhone theft is rather popular in New York. Indeed, Mayor Bloomberg recently suggested that it's responsible for an increase in crime in the city.


Anyway, the iPhone-less girl collared a couple of policemen, but the miscreant was not to be found.


However, the thief then decided that he'd try to get some money for the phone. So he met a man on a Flatbush street -- as you do.


The man asked to take a look at the phone. Perhaps he wanted to see whether Siri was still inside.


Then, he ran off with it.


Yes, this is slightly poetic. But we've only just begun.


You see, the boy thief was not very happy. After all, he'd had his recently acquired property stolen. So he went off in search of a policeman to report the crime.


I pause for your sound effects.


Thank you.



More Technically Incorrect


The police reacted with unusual efficiency. They corralled both the boy and the man who had taken Siri from him. But they still assumed the boy was the victim.


Are you ready for verse three?


The phone rang. It was the girl trying to do a deal to get her phone back. The police realized something might be amiss here. This seemed to be a miss who actually owned the phone.


So they waited for her to arrive in Flatbush. She recognized the boy's sneakers. They were pink.


I pause for your further sound effects.


The police decided it was time to play Solomon. They would slice the phone in two if one party didn't renounce their claim to the phone.


No, wait. They asked both the girl and the pink-sneakered boy to unlock the phone with the PIN code.


You're already there, aren't you? Both the actual thieves were brought to justice -- the actual kind. And the girl got her phone back.


There are several morals to this story.


One, don't steal iPhones if you're wearing pink sneakers.


Two, if someone does unto you as you have done unto someone else, take it onto the chin. It will help you understand the feelings of others.


Three, if you're the kind of New Yorker who thinks they can always get away with it, well, you can't. Not always.

Pictures: The Story Behind Sun Dogs, Penitent Ice, and More

Photograph by Art Wolfe, Getty Images

If you want the beauty of winter without having to brave the bone-chilling temperatures blasting much of the United States this week, snuggle into a soft blanket, grab a warm beverage, and curl up with some of these natural frozen wonders.

Nieve penitente, or penitent snow, are collections of spires that resemble robed monks—or penitents. They are flattened columns of snow wider at the base than at the tip and can range in height from 3 to 20 feet (1 to 6 meters). The picture above shows the phenomenon in central Chile. (See pictures of the patterns in snow and ice.)

Nieve penitente tend to form in shallow valleys where the snow is deep and the sun doesn't shine at too steep an angle, said Kenneth Libbrecht, a physicist at the California Institute of Technology in Pasadena who studies ice crystal formation.

As the snow melts, dirt gets mixed in with the runoff and collects in little pools here and there, he said. Since the dirt is darker in color than the surrounding snow, the dirty areas melt faster "and you end up digging these pits," explained Libbrecht.

"They tend to form at high altitude," he said. But other than that, no one really knows the exact conditions that are needed to form penitent snow.

"They're fairly strong," Libbrecht said. "People have found [the spires] difficult to hike through."

Newtown Families March for Gun Control in DC


Jan 26, 2013 4:59pm







gty gun control march washington jt 130126 wblog Newtown Victims Families Join Gun Control Activists on DC March

(YURI GRIPAS/AFP/Getty Images)


WASHINGTON, D.C. — Near-freezing temperatures didn’t stop several thousand gun-control activists from bearing their pickets today, carrying signs emblazoned with “Ban Assault Weapons Now” and the names of gun violence victims in a demonstration organized as a response to the mass shooting in Newtown, Conn. last month.


Walking in silence, the demonstrators trudged between Capitol Hill and the Washington Monument over a thin layer of melting snow. They were joined by politicians and some families of the Newtown victims.


March organizer Shannon Watts said the event was for the “families who lost the lights of their lives in Newtown, daughters and sons, wives and mothers, grandchildren, sisters and brothers gone in an unfathomable instant.”


“Let’s stand together and use our voices, use our votes to let legislators know that we won’t stand down until they enact common sense gun control laws that will keep our children out of the line of fire,” she told demonstrators.


Watts founded One Million Moms for Gun Control after the killing of 20 first graders and six adults at the Sandy Hook Elementary School in Newtown in December. In a profile with the New York Times, Watts said her 12-year-old son had suffered panic attacks after learning of last summer’s Aurora, Colo., theater shooting, leaving her at an impasse over how to talk to him about the latest tragedy.


Also among the speakers was a survivor of the 2007 Virginia Tech massacre, Collin Goddard.


“We need to challenge any politician who thinks it’s easier to ask an elementary school teacher to stand up to a gunman with an AR-15 than it is to ask them to stand up to a gun lobbyist with a checkbook,” he said.


The demonstration comes amid a push by progressive lawmakers to enact stricter gun control measures as a response to the trend of recent mass killings, although any hypothetical bill would likely face strong opposition in Congress.


Rep. Chris Van Hollen, D-Md., was among the demonstrators today.


“The idea that people need high-capacity magazines that can fire 30, 50, 100 rounds has no place in a civilized society,” he said. “Between the time we’re gathered here right now and this time of day tomorrow, across America, 282 Americans will have been shot.”


The congressman was quoting statistics compiled by the Brady Campaign to Stop Gun Violence.


INFOGRAPHIC: Guns by the Numbers


Last week President Obama proposed a sweeping overhaul of federal measures regulating gun ownership, including a universal background check system for sales, banning assault weapons,  and curbing the amount of ammunition available in weapon clips.


An ABC News/Washington Post poll released Thursday found 53 percent of Americans viewed Obama’s gun control plan favorably, 41 percent unfavorably. The division was visible today, as a handful of gun-rights advocates also turned out on the National Mall to protest what they believe would be infringements on their Second Amendment liberties.


ABC’s Joanne Fuchs contributed to this report.

Obama, Hollande hold phone talks on Mali offensive






WASHINGTON: US President Barack Obama voiced support Friday for France's military intervention in Mali and vowed to work with French counterpart Francois Hollande to tackle extremism across North Africa.

The two presidents discussed other "shared security concerns," including Algeria, Libya and Syria, during telephone talks, the White House said in a statement.

"The president expressed his support for France's leadership of the international community's efforts to deny terrorists a safe haven in Mali," it added.

In condemning a deadly hostage-taking operation by militants in Algeria last week, the two leaders "affirmed their mutual commitment to countering terrorism more broadly in North Africa," according to the statement.

Preliminary estimates from the Algerian authorities say 37 foreign hostages and 29 kidnappers died in an attack at the In Amenas gas field and in the military operation that followed.

Hollande also thanked Obama for his "significant support" of the effort in Mali, the White House said.

The US Air Force has deployed C-17 cargo planes to carry French troops and equipment to northern Mali, where they are trying to help flush out radical extremist fighters.

The United States also was providing intelligence to France, drawing on its network of satellites and surveillance drones.

Paris has asked Washington to help with refueling its warplanes taking part in the fight against militant fighters in Mali, but Obama's administration has yet to approve the request.

Obama and Hollande also "emphasized the need to rapidly establish" both an African-led military force in Mali and a "political roadmap that will lead to elections and restoration of democratic governance," the White House said.

The pair "condemned last week's terrorist act in Algeria," and "affirmed their mutual commitment to countering terrorism more broadly in North Africa."

Turning to Libya, in the wake of an uprising that toppled dictator Muammar Gaddafi in 2011, the two presidents "noted the importance of sustained assistance to Libya as it works to build effective security sector institutions," the statement added.

Hollande and Obama also spoke about Syria, "expressing their strong concern about the humanitarian crisis affecting not just Syria but also neighboring countries and reiterating their commitment to assisting the Syrian people achieve political transition to a post-Assad Syria," the statement said.

Syria's civil war has already claimed the lives of more than 60,000 people since March 2011, according to the United Nations, which has predicted that the number of Syrian refugees in neighboring countries will double to 1.1 million by June if the conflict does not end.

How I misjudged Vine, and came to see it as a new artform




I'll admit it, I misjudged Vine. Here's why.


One of the first things I read about Vine, Twitter's new stand-alone video app for iPhone and
iPod Touch, was Jack Dorsey's gushing tweet about the service.




"Vine is the most exciting thing I've seen in a while," Dorsey, Twitter's co-founder (and also founder of Square), tweeted yesterday morning. "Not just because of the team, because it brings an entirely new art form to the world."


I have a huge amount of respect for Dorsey -- after all, this is a man who helped change the way the world communicates, and then repeated that success by helping change the way the world pays for things. But I tend to tune out when an executive is so effusive in touting one of his or her company's own products. And that's what happened here: I automatically discounted Dorsey's praise and ignored the possibility that Vine could, in fact, offer the world a new art form.


It's also true that I didn't spend enough time with the app at first, and as a result I misunderstood what it was. I saw it as a simple six-second video that looped. Clearly, the digerati had anointed it the Thing of The Day, but I chalked that up to its being launched by Twitter. I thought it was derivative, and even a little annoying -- that looping thing could drive you crazy. I tweeted that if Vine had been entirely a stand-alone product, and not launched by Twitter, that few would care. Once the buzz died down, people would quickly tire of yet another video app, and within a week or two, Vine would fade away.


Fast forward a few hours, though, to an instant message conversation I had with my CNET colleague Jennifer Van Grove. She confided that she had been thinking more about Vine, and that she'd come to "understand why this is interesting [and] why it could matter."


In a bit of stream of consciousness, Van Grove rattled off a few reasons why she thought Vine might actually have some value: It makes the mundane seem interesting without requiring much work by the user; With no play button, the app presented no barrier to entry; It felt like something Tumblr should have built; and it offered a lot of appeal to teens, along the lines of Snapchat. "As much as I wanted to stay this is stupid," Van Grove said, "when I used it, I had fun. I was surprised, and I will use it."


When I got home, I pulled out the app to show it to my wife, who hadn't seen it. As I did, I stumbled across some of the videos that had been selected as Editor's Picks. The first to catch my eye was one in which a banana at first appeared whole, and then frame by frame, disappeared a piece at a time, as if by magic. On a loop, it was particularly clever because as soon as the banana was gone, it would reappear, again and again.


Sadly, one current limitation of Vine is that there's no way to get an embeddable code for an individual post, unless you can find a tweet in which it was included. As a result, there's no easy way for me to show the banana video. Here, though is a Vine I shot myself, showcasing the ability to shoot several individual moments and splice them all together:



It's now clear to me that I radically misunderstood how Vine works. Sure, you can use it to shoot an uninterrupted video of up to six seconds, but how mundane is that? In fact, the tool's real value is that it lets you very easily craft a video comprising six seconds of individual moments cobbled together into a final product. That opens up a whole world of short story-telling possibilities. For example, a major book publisher posted a Vine today showcasing their upcoming releases. They could have just panned from one book to the next in an uninterrupted shot, but this was much more dramatic.



Sure enough, in the early going, almost all of the most interesting Vines make full use of the tool's stop-motion/extended GIF capability, including the very first one ever posted, by Twitter CEO Dick Costolo, of someone cooking a special dish. A personal favorite of mine -- alas, another that I can't embed here, showed a line appearing on a piece of paper, and then morphing onto someone's hand, curving around, hitting their palm and turning into the word "fin," as in what you might see at the end of an art film.


By now, I was thinking again about Dorsey's tweet from the morning. Maybe he wasn't so far off. Vine has limitations, and it's too early to tell if it will have legs, but I'm coming to the conclusion that this is in fact an all-new art form. Put in the hands of clever, artistic types, there's very likely to be a never-ending supply of fun, interesting videos coming along -- accompanied, of course, by an infinite number of pointless ones.


It's not that Vine doesn't have some real problems. I'm still not convinced about the looping thing, and I wonder if over time, they'll provide a way to turn that off when viewing a Vine. At the same time, there doesn't appear to be a way to share others' videos -- you can't tweet someone else's Vine, in other words. And it's going to be hard for the service to grow all that fast without enabling that kind of sharing. But I imagine these are features that will emerge over time.


Either way, though, I expect a whole community of people to emerge who will coalesce around interesting, innovative Vines. Recall that that's exactly how Instagram took off -- by giving people attracted to artistic photography an easy to use tool and, even more importantly, an easy way to share their own and see others' creations. Boom! Ninety million active users.


Will Vine hit 90 million users? We're a long, long, long way from there. But with Twitter behind it and an enthusiastic community, I'm not willing to bet against it. At least not anymore.

'Hot' Guns Fueling Crime, US Study Says













Christmas is the one day of the year that Wal-Mart is closed, but for a group of four New Mexico burglars, it was the perfect time to stop in for some firearms.


Video surveillance cameras caught the masked burglars red-handed, stealing rifle after rifle. Police arrested the four men, and were able to recover the guns. But all too often, stolen weapons end up in the hands of criminals.


The New Mexico caper is part of a flood of gun thefts nationwide. And it's not only commercial gun dealers vulnerable to theft.


Guns are a top target for home burglars looking for something they can easily sell on the street.


An estimated 230,000 guns per year are stolen in home burglaries and property crimes, according to a study by the Department of Justice.


"Any burglar that goes in a house and finds guns, their eyes are going to light up," says former ATF Assistant Director Mike Bouchard. "That's the first thing they're going to take."


The statistics for commercial thefts show that nearly 25,000 guns per year are lost or stolen from gun dealers.


According to the Bureau of Alcohol Tobacco and Firearms (ATF), more than 4,000 gun stores and retailers have been targeted in the last three years, with 74,000 guns reported stolen or lost. And criminals will use any method possible to get their hands on some weapons, either for their own use, or to sell on the black market.

Obama on Gun Violence Measures: 'This Is Common Sense' Watch Video







Recently, thieves have taken to using a stolen vehicle to ram down the front doors of a gun store. In North Charleston, S.C., for example, burglars smashed a stolen truck right through Guns and Gold Trading Post, stealing $4,500 worth of guns before making a quick getaway.


"Gun stores are like candy stores for criminals," says Mike Bouchard.


2012 was a record year for gun sales, with more than 19.5 million background checks run for gun purchases, up almost 20% from the previous year. But while legitimate sales skyrocket, huge numbers of illegal guns are hitting the streets.


According to the Justice Department, more than 1.4 million guns were stolen or lost between 2005 and 2010.


Former ATF Assistant Director Bouchard says crooks have easy access to cheap stolen guns on the street.


"If you talk to any criminal, they can find a gun within an hour or two. Cheaper guns that were stolen can be sold for $50. On the street, a typical good handgun will run you $200 to $300," Bouchard said.


Some thieves have even targeted gun shipments, stealing the weapons before they get to market.


Last November, for example, a rogue truck driver allegedly stole a shipment of 111 guns he was supposed to deliver from the Smith and Wesson factory in Springfield, Mass.


When police caught him, they recovered 28 of the stolen guns, but some had already been used in crimes.


When police arrested the alleged stick-up robber known as the Black Jacket Bandit, they found one of the stolen guns was allegedly used by him in a convenience store robbery within weeks of the delivery heist.


In November, more than 100 powerful AK-47s were stolen from a rail yard in Atlanta. The guns were in a box car containing more than 1,000 guns being shipped from an overseas manufacturer to a major U.S. distributor, authorities say.


A few of the weapons have been recovered, but police are deeply concerned about having scores of new assault rifles falling into the wrong hands.


Given all the gun thefts, police say it is critical for gun owners to secure their weapons in gun safes or locked cases. And authorities are urging gun retailers to fortify their buildings, to try to prevent "smash and grab" type robberies.

Shrinking proton puzzle persists in new measurement



































A puzzle at the heart of the atom refuses to go away. The most precise measurement yet of the proton's radius confirms that it sometimes seems smaller than the laws of physics demand – an issue that has been hotly debated for two years.












The latest finding deepens the need for exotic physics, or some other explanation, to account for the inconsistency. "If we were in a hole before, the hole is deeper now," says Gerald Miller of the University of Washington in Seattle, who was not involved in the new measurement.












The saga of the proton radius began in 2010, when a group led by Randolf Pohl at the Max Planck Institute of Quantum Optics in Garching, Germany, determined the width of the fuzzy ball of positive charge – and found it was smaller than had been assumed.












Previous teams had inferred the proton's radius, which is impossible to measure directly, by studying how electrons and protons interact. One method uses the simplest atom, hydrogen, which consists of one electron and one proton. A quirk of quantum mechanics says that an electron in an atom can only orbit its proton at certain distances, corresponding to different energy levels. The electron can jump between levels if it absorbs or releases energy in the form of a photon of light.











Ball of charge













By measuring the energy of photons emitted by an excited hydrogen atom, physicists can figure out how far apart the energy levels are, and thus the distances of the permitted electron orbits. A theory called quantum electrodynamics then allows them to calculate how far the proton's ball of charge must extend to keep the electrons at those distances.












This method gave a charge radius for the proton that was about 0.877 femtometres, less than a trillionth of a millimetre.












Pohl and colleagues used a novel method. They created an exotic version of hydrogen that replaces the electron with a muon, a particle that has the same charge as the electron but is 200 times heavier. Its extra bulk makes it more sensitive to the proton's size, meaning radius measurements based on muons are orders of magnitude more precise.












The new method didn't just make the measurements more precise. It also changed them: the muonic hydrogen gave a radius of 0.8418 femtometres, 4 per cent less than before.











Scandalous result












That might not sound like much, but in the world of particle physics, where theory and experiment can agree to parts in a billion, it was scandalous. A lively discussion sprang up, with some physicists claiming problems with Pohl's experiments and interpretations, and others suggesting gaps in the standard model of particle physics.













Pohl and colleagues have now repeated their experiment. The measurement of the radius is now even more precise than in 2010 – and it is still 4 per cent smaller than the value from hydrogen-based experiments.












Pohl reckons that there are three likely explanations. His experiment could have errors, although the confirmation makes that less likely. Alternatively, the electron experiments could be off. "This would be the most boring possibility," says Pohl.












The third, and most exciting, possibility is that muons do not interact with protons in the same way as electrons. In other words, the proton's apparent radius changes a little bit depending on which particle it is interacting with.












If true, that might require the existence of unknown particles that alter the way the muon interacts with the proton. Those particles could, in turn, solve some of the problems with the standard model of particle physics. They could, for instance, provide a candidate for dark matter, the mysterious stuff that makes up more than 80 per cent of the mass in the universe.











Monumental idea













Miller, Pohl and Ron Gilman of Rutgers University in Piscataway, New Jersey helped organise a workshop with 50 proton experts in Trento, Italy, last October to hash out the details of the problem – and arrived at a verdict of sorts. "Because the muon experiments seem to be so solid, the most popular answers were that there's some beyond-the-standard-model physics differentiating between muon and electron, which would be very important," Gilman says.












"That would be monumental, truly," Miller says.












But Miller also has a less radical suggestion, which could reconcile all the measurements without invoking new particles. According to quantum electrodynamics, two charged particles can interact with each other by exchanging a photon – it's as if they spontaneously create a basketball and throw it between them, he says.












The equations also allow for a more complicated interaction where the particles create two balls, and juggle them. Until now this type of interaction was considered too rare to be important, but Miller reckons that the muon's greater mass could make it a better juggler. That would strengthen the proton's interaction with it and make the proton look smaller to the muon without requiring any new physics.












All these ideas will be up for review in a few years' time when new experiments, including shooting muons at protons to see how they scatter and building muonic helium atoms to measure their energy levels, are completed.












"It's quite likely that through other experiments, in two to three years we might get an end to this," Miller says. "It shouldn't take forever."

Australians warned to leave Benghazi immediately






SYDNEY: Australia on Friday joined three European nations in urging its citizens to leave the Libyan city of Benghazi due to a "specific, imminent threat to Westerners" linked to French action in Mali.

The advice followed similar warnings from governments in Britain, Germany and the Netherlands, which sparked an angry response from Libya's government. Tripoli said there was "no new intelligence" to justify such concerns.

But Australia's department of foreign affairs said: "We are aware of a specific, imminent threat to Westerners in Benghazi. All Australians in Benghazi should leave immediately.

"There is a risk of retaliatory attacks against Western targets in Libya following the French intervention in the conflict in Mali in January 2013," it said in an updated travel advice.

"A number of militant groups are known to operate in Libya and some may seek to target Western interests."

Only two Australians are registered as being in Benghazi and just 22 in Libya, said the department.

The alert came after US Secretary of State Hillary Clinton testified to Congress this week about the September attack on the US diplomatic mission in Benghazi that killed four Americans, including the ambassador to Libya.

It also comes as French troops battle Al-Qaeda-linked militants in Mali, amid rising concern about Islamist extremism across north Africa after last week's bloody attack on the In Amenas gas plant in Algeria.

During Microsoft's second-quarter earnings conference call today, the company's chief financial officer reiterated that the lineup of Surface devices will expand.


After Microsoft reported reported earning today, Chief Financial Officer Peter Klein spoke about future Surface products -- though he was mum about specifics.


"We had limited distribution this quarter in our stores and we're excited about expanding that [distribution]," he said, responding to an analyst's question.


"We're going to expand geographically, we're going to expand the product lineup, we're going to expand retail distribution and capacity," he said, in comments about Surface. Microsoft has made similar comments in the past.



Klein repeated a number of times that Surface contributed to revenue. "Certainly this quarter it was a contributing factor to revenue growth in the Windows business," Klein said.


And he inserted some serious commentary inside an innocuous-sounding statement. "It highlights some interesting innovation that can happen...demonstrates the power of
Windows 8 when tightly integrated with hardware and software."


In short, in order for a product to be done right, one company must make both the hardware and software -- as Apple has done successfully.



Klein did not mention -- and wasn't asked about -- shipment numbers for Surface RT. Speculation has been all over the map, though most analysts believe the number is somewhere in the neighborhood of a million.


The CFO also repeated previous comments by other Microsoft executives regarding the demand for Windows 8 touch devices. "There's great demand for touch devices," he said, adding that supply cannot keep up with demand.

Deformed Dolphin Accepted Into New Family


In 2011, behavioral ecologists Alexander Wilson and Jens Krause of the Leibniz-Institute of Freshwater Ecology and Inland Fisheries in Germany were surprised to discover that a group of sperm whales (Physeter macrocephalus)—animals not usually known for forging bonds with other species—had taken in an adult bottlenose dolphin (Tursiops truncatus).

The researchers observed the group in the ocean surrounding the Azores (map)—about 1,000 miles (1,600 kilometers) off the coast of Lisbon, Portugal—for eight days as the dolphin traveled, foraged, and played with both the adult whales and their calves. When the dolphin rubbed its body against the whales, they would sometimes return the gesture.

Among terrestrial animals, cross-species interactions are not uncommon. These mostly temporary alliances are forged for foraging benefits and protection against predators, said Wilson.

They could also be satisfying a desire for the company of other animals, added marine biologist John Francis, vice president for research, conservation, and exploration at the National Geographic Society (the Society owns National Geographic News).

Photographs of dogs nursing tiger cubs, stories of a signing gorilla adopting a pet cat, and videos of a leopard caring for a baby baboon have long circulated the Web and caught national attention.

A Rare Alliance

And although dolphins are known for being sociable animals, Wilson called the alliance between sperm whale and bottlenose dolphin rare, as it has never, to his knowledge, been witnessed before.

This association may have started with something called bow riding, a common behavior among dolphins during which they ride the pressure waves generated by the bow of a ship or, in this case, whales, suggested Francis.

"Hanging around slower creatures to catch a ride might have been the first advantage [of such behavior]," he said, adding that this may have also started out as simply a playful encounter.

Wilson suggested that the dolphin's peculiar spinal shape made it more likely to initiate an interaction with the large and slow-moving whales. "Perhaps it could not keep up with or was picked on by other members of its dolphin group," he said in an email.

Default

But the "million-dollar question," as Wilson puts it, is why the whales accepted the lone dolphin. Among several theories presented in an upcoming paper in Aquatic Mammals describing the scientists' observations, they propose that the dolphin may have been regarded as nonthreatening and that it was accepted by default because of the way adult sperm whales "babysit" their calves.

Sperm whales alternate their dives between group members, always leaving one adult near the surface to watch the juveniles. "What is likely is that the presence of the calves—which cannot dive very deep or for very long—allowed the dolphin to maintain contact with the group," Wilson said.

Wilson doesn't believe the dolphin approached the sperm whales for help in protecting itself from predators, since there aren't many dolphin predators in the waters surrounding the Azores.

But Francis was not so quick to discount the idea. "I don't buy that there is no predator in the lifelong experience of the whales and dolphins frequenting the Azores," he said.

He suggested that it could be just as possible that the sperm whales accepted the dolphin for added protection against their own predators, like the killer whale (Orcinus orca), while traveling. "They see killer whales off the Azores, and while they may not be around regularly, it does not take a lot of encounters to make [other] whales defensive," he said.

Feds Bust Man in Alleged Bombs-for-Drugs Sting


Jan 24, 2013 7:07pm







ht explosives in jeff co house tk 130124 wblog Federal Agents Bust Colorado Man in Alleged Bombs for Drugs Sting

Ryan Budnick/KMGH


A Colorado man who claimed to be a former demolition expert in the U.S. Marines was arrested Thursday after he allegedly tried to trade guns and homemade bombs with a 20-meter “kill zone” for cocaine.


Richard Lawrence Sandberg, 35, was taken into custody Thursday at his Morrison, Colo. home, ATF spokesman Bradley Beyersdorf told ABC News. Sandberg is facing one count of unlawful possession of a firearm or explosive device.


According to court documents, police became aware of Sandberg on January 18, when a confidential informant told a Denver police detective that Sandberg wanted to trade “numerous firearms and grenades” for drugs. The Denver police detective then contacted the Bureau of Alcohol, Tobacco, Firearms and Explosives.


On Tuesday, the documents say, an undercover ATF agent met with Sandberg at his home.


Sandberg allegedly told the undercover agent that he was in possession of 18 M67 military grenades that he offered to sell for $200 to $300 a piece, according to the criminal complaint.


The complaint did not say where Sandberg may have gotten the grenades, but said “Sandberg claimed to have been active in war zones in Iraq, Somalia, Africa, and Pakistan.”


“Sandberg also stated that he was in possession of several thousand rounds of ammunition and also in possession of uranium-tipped armor-piercing ammunition,” the complaint said.


In addition to the grenades, Sandberg allegedly claimed to have about a dozen homemade bombs, called “frags,” designed to create a “kill zone” within 20 meters and a “hurt zone” within 60 meters if they went off. The complaint says Sandberg also claimed to have access to C4 plastic explosives and napalm.


In one conversation, Sandberg “made disparaging remarks about the current administration and them wanting to take away his guns,” according to the complaint.

Bureau of Alcohol, Tobacco, Firearms and Explosives


If any law enforcement officers tried to take his guns, the complaint says Sandberg told the agent that “it would be a bad day for them and lots of them would die. Sandberg stated that he was ready and willing to die.”


At one point, the undercover ATF agent offered to pay for pipe bombs and a small explosive called a “cricket.” Sandberg refused, the complaint says, instead insisting that “they could set up a trade for cocaine.”


During the Thursday operation, the street in front of Sandberg’s home was blocked for several hours while ATF agents and three local bomb squads made sure the house was safe. Multiple improvised explosive devices were taken from the house and rendered safe at a remote location,according to U.S. Attorney’s spokesman Jeffrey Dorchner.


One house next door to Sandberg’s had to be temporarily evacuated, Beyersdorf said.


Sandberg appeared in federal court Thursday afternoon and was advised of the charges against him. He has not entered a plea. Sandberg is being held without bond until a detention hearing scheduled for Jan. 29, Dorchner said.

Wallace: Wonders of nature have been solace of my life






















Alfred Russel Wallace discovered natural selection independently of Charles Darwin. Through his letters, available online for the first time, he tells us of his research, expeditions and enduring fascination for nature's mysteries.






















You are famously joint author, with Darwin, of the first paper describing the origin of species and natural selection, published in 1858. When did you first get the idea?
I begin [in 1847] to feel rather dissatisfied with a mere local collection – little is to be learnt by it. I sh[ould]d like to take some one family, to study thoroughly – principally with a view to the theory of the origin of species. By that means I am strongly of [the] opinion that some definite results might be arrived at.












This desire led you to Brazil to collect birds, butterflies and beetles to try to discover what drives the evolution of new species. Were there any incidents on the voyage?
On Friday the 6th of August [1852]… the Captain (who was the owner of the vessel) came into the cabin & said "I am afraid the ship's on fire. Come & see what you think of it."












Despite that harrowing experience, you next undertook an 8 year expedition to the Malay Archipelago, where you discovered the invisible boundary between the animals of Asia and the Australian region, which would later be called the Wallace Line in your honour. What fascinated you most on that trip?
The Birds have however interested me much more than the insects, they are proportionally much more numerous, and throw great light on the laws of Geographical distribution of Animals in the East… As an instance I may mention the Cockatoos, a group of birds confined to Australia & the Moluccas, but quite unknown in Java Borneo Sumatra & Malacca… Many other species illustrate the same fact.












You have been famously good-natured about sharing the discovery of natural selection with Darwin…
I also look upon it as a most fortunate circumstance that I had a short time ago commenced a correspondence with Mr. Darwin on the subject of "Varieties", since it has led to the earlier publication of a portion of his researches & has secured to him a claim to priority which an independent publication either by myself or some other party might have injuriously effected












What did you and Darwin have in common?
In early life both Darwin and myself became ardent beetle-hunters. Both Darwin and myself had, what he terms "the mere passion of collecting"… Now it is this superficial and almost child-like interest in the outward forms of living things, which, though often despised as unscientific, happened to be the only one which would lead us towards a solution of the problem of species.












Do you feel your contribution has been overlooked?
The idea came to me, as it had come to Darwin, in a sudden flash of insight: it was thought out in a few hours – was written down with such a sketch of its various applications and developments… then copied on thin letter-paper and sent off to Darwin – all within one week.












I should have had no cause for complaint if the respective shares of Darwin and myself in regard to the elucidation of nature's method of organic development had been thenceforth estimated as being, roughly, proportional to the time we had each bestowed upon it when it was thus first given to the world – that is to say, as 20 years is to one week.












You helped Darwin with the puzzle of bright colouration in animals, which led to the concept of warning colours. To ask his question again, why are some caterpillars so brightly coloured?
[Since some]… are protected by a disagreeable taste or odour, it would be a positive advantage to them never to be mistaken for any of the palatable caterpillars… Any gaudy & conspicuous colour therefore, that would plainly distinguish them from the brown & green eatable caterpillars, would enable birds to recognise them easily as a kind not fit for food, & thus they would escape seizure which is as bad as being eaten.












How did you feel looking back on your life's work, at the age of 89?
The wonders of nature have been the delight and solace of… life. Nature has afforded… an ever increasing rapture, and the attempt to solve some of her myriad problems an ever-growing sense of mystery and awe.












Do you have a message for our readers?
I sincerely wish you all some of the delight in the mere contemplation of nature's mysteries and beauties which I have enjoyed.

More covered linkways, elderly friendly bridges for commuters






SINGAPORE: The government will spend close to S$700 million to make transport nodes more accessible, elderly friendly and conducive for commuters.

The plans, mapped out in the new Land Transport Master Plan, were announced by Transport Minister Lui Tuck Yew on Wednesday.

One of the new initiatives -- Walk2Ride -- will make it easier for more commuters to walk to MRT stations.

The Land Transport Authority (LTA) will build sheltered linkways within a 400-metre radius from all existing MRT stations, compared to the current radius of 200 metres.

LTA will also link up developments within a 200-metre radius of all bus interchanges, LRT stations and high-usage bus shelters.

In all, some 200 kilometres of linkways will be added islandwide by 2018, more than four times the existing 46 kilometres today.

The project is expected to cost some S$330 million and will begin from 2014.

Currently, sheltered linkways are built to link only to schools, healthcare institutions and other transport nodes like bus stops and taxi stands.

But under Walk2Ride, shopping, leisure, commercial and residential areas will also be linked.

LTA intends to leverage on existing linkways and work with the different town councils before deciding on which areas will be given priority.

The Walk2Ride initiative is being rolled out, following a successful trial at Lakeside MRT.

More pedestrian overhead bridges will also become more elderly and wheel-chair friendly.

LTA has reviewed the provision criteria to build more lifts at such bridges. These include those located within 200 metres of MRT stations and 100 metres of LRT stations.

Some 40 bridges have been identified for further feasibility studies.

A budget of about S$60 million has been set aside to install the lifts from 2014. Half of them will be completed by 2016 and the remaining by 2018.

Another S$300 million will be spent on installing some 20 kilometres of noise barriers along elevated MRT tracks.

Since September, LTA has been measuring noise levels at 455 residential flats located close to such tracks.

In some locations, the noise levels were found to have exceeded the National Environment Agency's guideline of 67 decibels.

Mr Lui said residents living close to MRT viaducts, such as those in Simei, Marsiling and Dover, can expect noise levels to be reduced by about five to 10 decibels.

LTA intends to start installing the barriers from end of this year and complete them by 2020.

Deformed Dolphin Accepted Into New Family

Clinton on Benghazi: Afghanistan Diverted Resources













House Republicans slammed Secretary of State Hillary Clinton today for her lack of awareness of State Department cables warning of security threats in Benghazi, Libya, prior to the Sept. 11 attack that killed four Americans, including Amb. Chris Stevens.


In the second congressional hearing of the day reviewing a report by the Accountability Review Board on the State Department's security failures, Rep. Michael McCaul, R-Texas, asked Clinton this afternoon why her office had not responded to a notification from Stevens about potential dangers in Libya.


"Congressman, that cable did not come to my attention," Clinton calmly told the House Foreign Affairs Committee hours after her Senate testimony this morning. "I'm not aware of anyone within my office, within the secretary's office having seen that cable."


She added that "1.43 million cables come to my office. They're all addressed to me."


Hillary Clinton's Fiery Moment at Benghazi Hearing


Rep. Matt Salmon, R-Ariz., asked Clinton whether she thought that signaled the need for a shifting of priorities to make sure she is notified about these kinds of threats in the future.


"That's exactly what I'm intent on doing," Clinton said. "We have work to do. We have work to do inside the department. We have work to do with our partners in DOD and the intelligence community."


Such answers failed to appease members like Rep. Jeff Duncan, R-S.C., who accused Clinton of letting "the consulate become a death trap."


Clinton also told the House committee that an emphasis on security in Iraq and Afghanistan in the past decade diverted resources from other outposts around the world.


She told Rep. Chris Smith, R-N.J., that legislation he championed reorganizing the State Department in the 19990s had "been very important in protecting our people around the world," but that the need for funding was ongoing and unmet.


Clinton reprised her role as defender of the State Department this afternoon in the second half of congressional testimony on the security failures that led to the deaths of Stevens and the other Americans.


Stevens understood the significance of the mission, she told the committee several hours after a morning Senate appearance.


"That's why Chris Stevens went to Benghazi in the first place," she said. "Nobody knew the dangers better than Chris, first during the revolution and then during the transition. A weak Libyan government, marauding militias, even terrorist groups … a bomb exploded in the parking lot of his hotel. He never wavered. He never asked to come home. He never said let's shut it down, quit, go somewhere else."


Representatives repeatedly asked about U.N. Ambassador Susan Rice's assertion on Sunday morning talk shows in September that the attack was fueled by outrage over a video attacking Islam.

Hillary Clinton Gets Choked Up at Benghazi Hearing Watch Video





Clinton's response was to refer to the ARB report, which said the motivations behind the attack were complicated and still not all known. She maintained that Rice was speaking based upon talking points given to her by the intelligence community.


Rep. Joe Wilson, R-S.C., asked why the secretary of state herself did not appear in Rice's place to give those televised explanations to the country.


"Well, I have to confess here in public [that] going on the Sunday shows is not my favorite thing to do. There are other things that I prefer to do on Sunday mornings," Clinton replied. "And I did feel strongly that we had a lot that we had to manage, that I had to respond to. And I thought that should be my priority."


The afternoon appearance followed morning testimony from an energized Clinton, who stood her ground and told the Senate Foreign Relations Committee that she has overseen plans to secure diplomatic outposts around the world while cuts in State Department funding undermine those efforts.


Citing a report by the department's Accountability Review Board on the security failures that led to the deaths of four Americans in Benghazi, Libya, during an attack last year, Clinton said the board is pushing for an increase in funding to facilities of more than $2 billion per year.


"Consistent shortfalls have required the department to prioritize available funding out of security accounts," Clinton told the Senate this morning, while again taking responsibility for the Benghazi attack. "And I will be the first to say that the prioritization process was at times imperfect, but as the ARB said, the funds provided were inadequate. So we need to work together to overcome that."


Clinton, showing little effect from her recent illnesses, choked up earlier in discussing the Benghazi attack.


"I stood next to President Obama as the Marines carried those flag-draped caskets off the plane at Andrews," Clinton said this morning, her voice growing hoarse with emotion. "I put my arms around the mothers and fathers, sisters and brothers, sons and daughters."


The outgoing secretary of state was the only witness to giving long-awaited testimony before the Foreign Relations Committee this morning, and appeared before the House Foreign Affairs Committee at 2 p.m.


The secretary, who postponed her testimony in December, started today by giving context to the terrorist attack.


"Any clear-eyed examination of this matter must begin with this sobering fact," Clinton began. "Since 1988, there have been 19 Accountability Review Boards investigating attacks on American diplomats and their facilities."


But the secretary did not deny her role in the failures, saying that as secretary of state, she has "no higher priority and no greater responsibility" than protecting American diplomats abroad like those killed in Benghazi.


"As I have said many times, I take responsibility, and nobody is more committed to getting this right," Clinton said. "I am determined to leave the State Department and our country safer, stronger and more secure."


Among the steps Clinton has taken, she said, is to "elevate the discussion and the decision-making to make sure there's not any" suggestions that get missed, as there were in this case.


Clinton testified that the United States needs to be able to "chew gum and walk at the same time," working to shore up its fiscal situation while also strengthening security, and she refuted the idea that across-the-board cuts slated to take place in March, commonly referred to as sequestration, were the way to do that.


"Now sequestration will be very damaging to the State Department and USAID if it does come to pass, because it throws the baby out with the bath," Clinton said, referring to the United States Agency for International Development, which administers civilian foreign aid.


While the State Department does need to make cuts in certain areas, "there are also a lot of very essential programs … that we can't afford to cut more of," she added.


More than four months have passed since the attack killed U.S. Ambassador Christopher Stevens and three other Americans in Libya. These meetings, during which Clinton discussed the report on State Department security failures by the Accountability Review Board, were postponed because of her recent illness.


Clinton told the Senate that the State Department is on track to have 85 percent of action items based on the recommendations in the ARB report accomplished by March, with some already implemented.

MIT website hacked in tribute to Aaron Swartz



Hal Hodson, technology reporter

A tribute to internet activist Aaron Swartz replaced the homepage for the Massachusetts Institute of Technology today, in an apparent act of protest over the university's role in the legal case that led up to Swartz's suicide on 11 Jan.

For a short time, visitors to the MIT.edu home page found a message that read: "R.I.P. Aaron Swartz. Hacked by grand wizard of Lulzsec, Sabu. God Bless America. Down With Anonymous." The background was watermarked with words from a blog post, written by Swartz, titled "Immoral".

Attributing the defacement to "grand wizard of Lulzsec, Sabu" lent the page a sarcastic air, as it's widely known that the former Lulzsec leader was outed as an FBI informant last year.

The attack on MIT's website came amid widespread criticism of how the university handled the case against Swartz, including an article in The New York Times that quoted Swartz's father as saying: "We don't believe [MIT] acted in a neutral way. My belief is they put their institutional concerns first."

According to MIT's service status page, network service was restored within the university as of 1:30 pm EST. The university had not yet returned New Scientist's request for comment when this story was published.

This is the second time since Swartz' death that the MIT site has been the target of attacks. Previously, an MIT sub-domain was replaced with a manifesto for reform of computer and copyright laws. The authors claimed to be operating as a part of the online activist group, Anonymous.

British PM to offer "in-or-out" referendum on EU






LONDON: Prime Minister David Cameron will on Wednesday propose holding a referendum after 2015 giving British people the choice of staying in or leaving the European Union.

Cameron will say in a long-awaited speech in London that he wants to renegotiate the terms of Britain's membership because "public disillusionment with the EU is at an all-time high", and then put the new terms to the people.

According to pre-released excerpts, Cameron will say his Conservative party will make the pledge in its campaign for the general election scheduled to take place in two years' time.

"The next Conservative manifesto in 2015 will ask for a mandate from the British people for a Conservative government to negotiate a new settlement with our European partners in the next parliament," the speech says.

"And when we have negotiated that new settlement, we will give the British people a referendum with a very simple in-or-out choice to stay in the EU on these new terms, or come out altogether. It will be an in-out referendum."

If a Conservative government wins outright victory, a referendum would be held in the first half of the next parliament, he adds.

Cameron will say he believes a referendum on British membership of the 27-nation bloc is necessary because in its current form the EU is intruding into British life.

"People feel the EU is heading in a direction they never signed up to. They resent the interference in our national life by what they see as unnecessary rules and regulation. And they wonder what the point of it all is," he will say.

Cameron had been due to give the speech in Amsterdam last Friday but postponed it because of the Algeria gas plant hostage crisis.

In the re-scheduled speech, Cameron says he understands the "impatience" of those who want to hold a referendum immediately, but insists the time is not right.

"I don't believe that to make a decision at this moment is the right way forward, either for Britain or for Europe as a whole," it says.

"A vote today between the status quo and leaving would be an entirely false choice."

Explaining why he wants to wait, Cameron will say the eurozone crisis will leave the EU transformed "perhaps beyond recognition" and that Britain wants to help shape the future of the bloc that emerges from it.

Cameron has faced pressure from the eurosceptic rightwing of the Conservative Party to take a stand on Europe, an issue that has long divided the party.

But his insistence on holding a referendum with a stark in-or-out choice will anger many of Britain's fellow EU member states, as well as his coalition government partners, the pro-Europe Liberal Democrats.

It will also dismay many business leaders and the opposition Labour party, who have warned Cameron that to offer the possibility of a referendum risks creating uncertainty and will lead Britain to the edge of an "economic cliff".

Cameron has also faced warnings from Britain's close ally the United States against isolating the country from the EU.

The speech has been delayed a number of times.

Plans to give it first emerged six months ago, and there was talk that Cameron might deliver it at the Conservative party's annual conference in October, followed by reports that he would give it at Christmas.

The speech was then widely expected on January 22, but Cameron moved it forward when it emerged that it clashed with commemorations for the 50th anniversary of Franco-German reconciliation following World War II.

Then the Algeria crisis intervened to force another change of plans.

To add further excitement to the reveal, Zenimax also opened the doors to Elder Scrolls Online beta registrations today, giving anyone the chance to get in on the action. Of course, to get in, you'll need to submit answers to an array of personal questions (name, birthday, and so on) and submit full system diagnostic information. Zenimax also requires that you answer questions about any other relevant MMORPGs you've played; your play style (solo, group, etc.); preferred activities in MMORPGs; and previous stints as a beta tester.




If that wasn't demanding enough, you then have to tell the developer why you should be chosen as a beta tester. Amusingly, a progress bar hangs over the Web page and indicates your chance rating at even being selected at all -- fortunately, I scored an above-average, so I assume experience matters.


Zenimax and publisher Bethesda Softworks didn't disclose when The Elder Scrolls Online would begin beta testing, or reveal much information other than the fact that PC and
Mac gamers can participate. Read the beta FAQ for more details, or listen to the latest Bethesda podcast featuring developers answering some more questions about the upcoming experience.

The Promise and Perils of Mining Asteroids


Encouraged by new space technologies, a growing fleet of commercial rockets and the vast potential to generate riches, a group of entrepreneurs announced Tuesday that they planned to mine the thousands of near-Earth asteroids in the coming decades.

The new company, Deep Space Industries (DSI), is not the first in the field, nor is it the most well-financed. But with their ambition to become the first asteroid prospectors, and ultimately miners and manufacturers, they are aggressively going after what Mark Sonter, a member of DSI's board of directors, called "the main resource opportunity of the 21st century." (Related: "Asteroid Hunter to Be First Private Deep-Space Mission?")

Prospecting using miniaturized "cubesat" probes the size of a laptop will begin by 2015, company executives announced. They plan to return collections of asteroid samples to Earth not long after.

"Using low cost technologies, and combining the legacy of [the United States'] space program with the innovation of today's young high tech geniuses, we will do things that would have been impossible just a few years ago," said Rick Tumlinson, company chairman and a longtime visionary and organizer in the world of commercial space [not sure what commercial space means].

"We sit in a sea of resources so infinite they're impossible to describe," Tumlinson said.

Added Value

There are some 9,000 asteroids described as "near-Earth," and they contain several classes of resources that entrepreneurs are now eyeing as economically valuable.

Elements such as gold and platinum can be found on some asteroids. But water, silicon, nickel, and iron are the elements expected to become central to a space "economy" should it ever develop.

Water can be "mined" for its hydrogen (a fuel) and oxygen (needed for humans in space), while silicon can be used for solar power systems, and the ubiquitous nickel and iron for potential space manufacturing. (See an interactive on asteroid mining.)

Sonter, an Australian mining consultant and asteroid specialist, said that 700 to 800 near-Earth asteroids are easier to reach and land on than the moon.

DSI's prospecting spacecraft will be called "FireFlies," a reference to the popular science fiction television series of the same name. The FireFlies will hitchhike on rockets carrying up communication satellites or scientific instruments, but they will be designed so that they also have their own propulsion systems. The larger mining spacecraft to follow have been named "DragonFlies."

Efficiencies

It all sounds like science fiction, but CEO David Gump said that the technology is evolving so quickly that a space economy can soon become a reality. Providing resources from beyond Earth to power spacecraft and keep space travelers alive is the logical way to go.

That's because the most expensive and resource-intensive aspect of space travel is pushing through the Earth's atmosphere. Some 90 percent of the weight lifted by a rocket sending a capsule to Mars is fuel. Speaking during a press conference at the Santa Monica Museum of Flying in California, Gump said that Mars exploration would be much cheaper, and more efficient, if some of the fuel could be picked up en route.

Although there is little competition in the asteroid mining field so far, DSI has some large hurdles ahead of it. The first company to announce plans for asteroid mining was Planetary Resources, Inc. in spring 2012—the group is backed by big-name investors such as Google's Larry Page and Eric Schmidt, filmmaker James Cameron, and early Google investor Ram Shriram. DSI is still looking for funding.

Owning Asteroids

While these potential space entrepreneurs are confident they can physically lay claim to resources beyond Earth, there remain untested legal issues.

The United Nations Space Treaty of 1967 expressly forbids ownership of other celestial bodies by governments on Earth. But American administrations have long argued that the same is not true of private companies and potential mining rights.

While an American court has ruled that an individual cannot own an asteroid—as in the case of Gregory Nemitz, who laid claim to 433 Eros as a NASA spacecraft was approaching it in 2001—the question of extraction rights has not been tested.

Moon rocks brought back to Earth during the Apollo program are considered to belong to the United States, and the Russian space agency has sold some moon samples it has returned to Earth-sales seen by some as setting a precedent.

Despite the potential for future legal issues, DSI's Gump said his group recently met with top NASA officials to discuss issues regarding technology and capital, and came away optimistic. "There's a great hunger for the idea of getting space missions done with smaller, cheaper 'cubesat' technology and for increased private sector involvement."

Everyone involved acknowledged the vast challenges and risks ahead, but they see an equally vast potential—both financial and societal.

"Over the decades, we believe these efforts will help expand the civilization of Earth into the cosmos, and change what it means to be a citizen of this planet," Tumlinson said.
