Soft-bodied robots squeeze closer

The US defence agency DARPA decided last year that it needed "Chemical Robots" (ChemBots) that could change shape in order to squeeze through small gaps. It's now chosen the people to provide them - US firm iRobot. The company makes the Roomba robot vacuum cleaner (video) and the 'Packbot' used for bomb disposal.
The DARPA programme manager overseeing the project gave a hint at what the robots could be used for:

"During military operations it can be important to gain covert access to denied or hostile space... We believe that a new class of soft, flexible, meso-scale mobile objects that can identify and maneuver through openings smaller than their dimensions to perform various tasks will be quite valuable in many missions."

But as we noted in a special report on DARPA's 50 years of pioneering ideas - many of its projects have made most impact in civilian arenas.

According to the original proposal from DARPA, in just 2 years a prototype approximately the size of a softball - i.e. 10cm across - must achieve all this:

a) travel a distance of 5 meters at a speed of 0.25 meters/minute;
b) achieve a 10-fold reduction in its largest dimension; and
c) squeeze through a 1 cm opening of arbitrary geometry and reconstitute its original size and shape, in 15 seconds.

That's quite a challenge - I wonder how they'll do it? Perhaps a variant of this shape-changing self-rolling wheel could work. Although the version in the image below looks very mechanical, the design could be made in soft materials.

Two unique minds meld in 'A Dangerous Method'

TORONTO – By all rights, David Cronenberg and Viggo Mortensen should be mortal enemies.

Cronenberg, 68, a Toronto native with a storied career as a director, made his mark with body-mangling horror (The Fly, Videodrome) and roots for pro hockey's Maple Leafs.
Actor Viggo Mortensen teams up with director
David Cronenburg for the third time on 'A Dangerous Method.'
Mortensen, 53, the Danish-American actor who lorded over The Lord of the Rings as warrior Aragorn, backs the rival Montreal Canadiens. And he likes nothing better than to rile the locals whenever attending the film festival here by proudly sporting his team's memorabilia.

Instead, they have melded into a potent creative unit as they talk about their just-opened third effort together, A Dangerous Method. The two are cut from the same cloth, thoughtful and perceptive. But there's also a remnant of sly humor.

As an apologetic Mortensen rushes into an interview about 10 minutes late, he asks Cronenberg, "What are you saying?" Teases the director with a pinch of French Canadian: "I am only saying bad things about you comme d'habitude" — which means "as usual."

Their previous collaborations, 2005's A History of Violence and 2007's Eastern Promises (which earned Mortensen his first Oscar nomination), were action thrillers. Method, however, is a different sort of madness. As Cronenberg says, "It's the action of the mind."

Fans of both might be taken aback by the fact-based period piece that details the meeting of two titans of psychoanalysis, Vienna-based Sigmund Freud (Mortensen) and Swiss acolyte Carl Jung (Michael Fassbender), as World War I threatens.

The pair are proponents of the "talking cure," and Jung has found the perfect guinea pig to test out his theories: a highly intelligent yet acutely disturbed Russian woman, Sabina Spielrein, brought to life with jaw-jutting contortions and hysterical screams by Keira Knightley.

Mining Freud's artist side

The subject matter isn't that strange for Cronenberg , who is quick to point out that his first film, a 1966 short titled Transfer, was about a psychiatrist and his patient.

But rarely has one of his films been so dialogue-driven, despite the occasional interlude of kinky S&M between the married Jung and Spielrein, an affair that caused a rift between the doctors. And rarely has Mortensen seemed so authoritarian and stately, even with a phallic cigar always within reach on-screen.
The director is aware that a film as dense with ideas as Method poses certain challenges for the audience. "We knew we were making a film that is like that," Cronenberg says, adding that a second viewing wouldn't hurt. "But there are a lot of instant-consumption movies. You eat them and they're gone."

One matter to chew over: a neo-hippie like Mortensen embodying the grizzled, tweed-suited father of psychiatry. Even the actor initially had a difficult time picturing himself as Freud. Says the director: "It's not obvious casting. It took a phone call from me to encourage Viggo."

Mortensen eventually gave in. "If another director had asked me, I probably wouldn't have taken the plunge. But because I know him and I trust him and we communicate well, I agreed. I wasn't sure. But then I felt there was something to it. It's fun to surprise people now and then. I feel good about it."

As someone who prides himself on his cultural pursuits beyond Hollywood, including painting, poetry and music, Mortensen managed to find a connection to Freud the artist.

"One of my favorite quotes of Freud's is when he says, 'Every place I go I find a poet has been there before me,' " Mortensen says. "He thought of himself as a literary figure. And other people did, too. There were academics who seriously were pushing for him to be nominated for a Nobel Prize. But there was a difference of opinion whether it should be for science or literature."

Darkened eyes, a fake nose, facial hair and about 20 extra pounds also helped him pull off the illusion. Besides, Cronenberg was showing a Freud in his prime. "Not the old frail man we all know, bearded and skinny," he says.

Mortensen's wider range

Given the shrink-wrapped circumstances, it's highly appropriate that Fassbender declares it was "just a dream" being a boundary-breaking Jung opposite Mortensen's wily Freud, adding, "He's such an original dude." As for Cronenberg, "his films have a darker edge to them, but he is so light, generous and loving. Viggo said, 'It's different working with David,' and it is. They both have such a strong bond. But they are both generous and open, too."

Although Cronenberg claims he first hired Mortensen for Violence "because he was cheap," the star also was hot off his success in Rings and had built a loyal following. The actor, meanwhile, was fearful of being typecast by the trilogy that ended in 2003. "I wanted to remind people I didn't come from Middle Earth."
The result is a relationship that will likely continue for some time. The director's analysis? "It's inevitable."

Feds seize 150 websites in counterfeit crackdown

WASHINGTON – Federal authorities have shut down 150 websites accused of selling knock-off or pirated merchandise to unsuspecting online bargain hunters.

Immigration and Customs Enforcement Director John Morton and Assistant U.S. Attorney Lanny A. Breuer announced the results of the ICE and FBI three-month investigation on "Cyber Monday," the day that for many shoppers kicks off the online holiday shopping season.

The government seized the domain names for the sites that sold everything from fake replica NBA jerseys to replica Louis Vuitton handbags and imitation Ugg boots.

"This is straight crime," Morton said. "This is people being duped into buying a counterfeit."
The federal government has seized the domain names of 350 websites since first targeting online counterfeiters in June 2010. Each investigation, Morton said, has grown.

Visitors to the seized domains are now greeted with a message from federal authorities explaining that the site has been seized by the government and a warning that "willful copyright infringement is a federal crime."
Morton and Breuer said while the domain names were registered in the United States most of the websites were run from abroad, primarily in China. No one has been charged with a crime in connection with the most recently seized domains. But Breuer said the investigations are ongoing.

Earlier this year five people were indicted in Virginia on conspiracy and copyright infringement charges for their roles in operating a website that the Justice Department said allowed people to illegally download high-quality movies and television shows.

Four people accused of running NinjaVideo.net have pleaded guilty. A fifth person is being sought.
It's unclear how much money the seized sites have made, or potentially cost legitimate companies. Breuer said since the crackdown on counterfeit sellers started last year, Internet users have gone to the seized domains more than 77 million times.

"Typically we don't track the volumes of sales of these particular sites," Morton said, adding that criminal organizations often hide ill-gotten profits. "It is very large figures. Well, well above millions."
Morton said it may seem like a trivial thing to buy a knock-off football jersey or look-alike sunglasses, but the profits seized by counterfeiters can help fund far more nefarious activities.

"This is increasingly not simply a matter of mom and pop violations at the corner of Fourth and Main," Morton said. "We are worried about organized crime and (that profits) are going to fuel other criminal activity."

Morton would not say if organized criminal groups are suspected of running any of the seized sites to help fund other criminal acts.

40,000 troops to leave Afghanistan by end of 2012

Afghan villagers look on as a U.S. soldier keeps watch during a mission.
KABUL, Afghanistan (AP) – Drawdown plans announced by the U.S. and more than a dozen other nations will shrink the foreign military footprint in Afghanistan by 40,000 troops at the close of next year, leaving Afghan forces increasingly on the frontlines of the decade-long war.


The United States is pulling out the most — 33,000 by the end of 2012. That's one-third of 101,000 American troops who were in Afghanistan in June — the peak of U.S. military presence in the war, according to figures provided by the Pentagon.

Others in the 49-nation coalition have announced withdrawal plans too, even as they insist they are not rushing to leave. Many nations have vowed to keep troops in Afghanistan to continue training the Afghan police and army in the years to come. And many have pledged to keep sending aid to the impoverished country after the international combat mission ends in 2014.

Still, the exit is making Afghans nervous.

They fear their nation could plunge into civil war once the foreign forces go home. Their confidence in the Afghan security forces has risen, but they don't share the U.S.-led coalition's stated belief that the Afghan soldiers and policemen will be ready to secure the entire nation in three years. Others worry the Afghan economy will collapse if foreigners leave and donors get stingy with aid.

Foreign forces began leaving Afghanistan this year.

About 14,000 foreign troops will withdraw by the end of December, according to an Associated Press review of more than a dozen nations' drawdown plans. The United States is pulling out 10,000 service members this year; Canada withdrew 2,850 combat forces this summer; France and Britain will each send about 400 home; Poland is recalling 200; and Denmark and Slovenia are pulling out about 120 combined.
Troop cutbacks will be deeper next year when an estimated 26,000 more will leave. That figure includes 23,000 Americans; 950 Germans; 600 more French; 500 additional Britons; 400 Poles; 290 Belgians; 156 Spaniards; and 100 Swedes.

Gen. James F. Amos, commandant of the Marine Corps, told the AP that the number of Marines in Helmand province in southern Afghanistan will drop "markedly" in 2012, and the role of those who stay will shift from countering the insurgency to training and advising Afghan security forces.

Amos declined to discuss the number of Marines expected to leave in 2012.

There are now about 19,400 Marines in Helmand, and that is scheduled to fall to about 18,500 by the end of this year.

"Am I OK with that? The answer is 'yes,'" Amos said. "We can't stay in Afghanistan forever."
"Will it work? I don't know. But I know we'll do our part."

Additional troop cuts or accelerated withdrawals are possible.
Many other countries, including Hungary, Finland and Italy, are finalizing their withdrawal schedules. Presidential elections in Europe and the European debt crisis also could speed up pullout plans. Australian Prime Minister Julia Gillard said this week that Australia's training mission could be completed before the 2014 target date.

Back in June, then-U.S. Defense Secretary Robert Gates said that when the Obama administration begins pulling troops from Afghanistan, the U.S. will resist a rush to the exists, "and we expect the same from our allies." Gates said it was critically important that a plan for winding down NATO's combat role by the end of 2014 did not squander gains made against the Taliban that were won at great cost in lives and money.

"The more U.S. forces draw down, the more it gives the green light for our international partners to also head for the exits," said Jeffrey Dressler, a senior research analyst at the Institute for the Study of War in Washington. "There is a cyclical effect here that is hard to temper once it gets going."

U.S. Army Lt. Col. Jimmie Cummings Jr. said the cutbacks that have been announced will not affect the coalition's ability to fight the insurgency.
"We are getting more Afghans into the field and we are transferring more responsibility to them in many areas," Cummings said, adding that many leaders of the Taliban, al-Qaida and the Haqqani militant networks have been captured or killed.

Afghan security forces started taking the lead in seven areas in July. They soon will assume responsibility for many more regions as part of a gradual process that will put Afghans in charge of security across the nation by the end of 2014.

Some countries are lobbying to start transition as soon as possible in areas where they have their troops deployed — so they can go home, said a senior NATO official, who spoke on condition of anonymity to discuss transition. The official insisted that those desires were not driving decisions on where Afghan troops are taking the lead. But the official said that because they want to leave, a number of troop-contributing nations faced with declining public support at home have started working harder to get their areas ready to hand off to Afghan forces.

"The big question (after 2014) is if the Afghan security forces can take on an externally based insurgency with support from the Pakistani security establishment and all that entails," Dressler said. "I think they will have a real challenge on their hands if the U.S. and NATO countries do not address Pakistani sponsorship of these groups."
