Newtown Families March for Gun Control in DC

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.

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.

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."

'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.

Washington Teen Allegedly Helped Steal Father's Guns Watch Video

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.

Microsoft: We're going to broaden Surface lineup

(Credit:
Brooke Crothers)

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.
