Obama Promises Faster Transition in Afghanistan

President Obama and Afghan President Hamid Karzai said today that most U.S. combat operations in Afghanistan would end this spring, signaling a quickening troop drawdown that will bring the decade-long war to a close at the end of 2014.

"Our troops will continue to fight alongside Afghans when needed, but let me say it as plainly as I can: Starting this spring, our troops will have a different mission -- training, advising, assisting Afghan forces," Obama announced at an East Room news conference in Washington.

"It will be a historic moment and another step toward full Afghan sovereignty, something I know that President Karzai cares deeply about, as do the Afghan people," he said.

Administration officials said Afghan forces were "exceeding initial expectations" in their capabilities. Afghan security forces are expected to lead 90 percent of security operations across the country in February.

"By the end of next year -- 2014 -- the transition will be complete," Obama said. "Afghans will have full responsibility for their security, and this war will come to a responsible end."

The rosy assessments belied the serious political, economic and security challenges that remain.

Left unanswered by Obama and Karzai: How many U.S. troops might stay after 2014; what their mission would be and whether they could be effective; and whether the forces would have immunity from prosecution in Afghan courts.

Obama said he was still reviewing recommendations from the Pentagon and will make an announcement in the coming weeks after penning an anticipated bilateral security agreement with Afghanistan. Karzai said the exact number would be up to the United States to decide.

Both leaders confirmed in a statement that the United States "does not seek permanent bases in Afghanistan."

They also agreed today to turn over battlefield combatants held by the U.S. military in Afghanistan to Afghan government control, which has been long-sought by Karzai.

Roughly 66,000 U.S. troops are serving in Afghanistan. The military has proposed keeping several thousand troops in the country after 2014 as advisers, trainers and logistical support for Afghan forces; the White House has said it remains open to pulling out all troops entirely.

Obama's visit with Karzai was the first face-to-face encounter since the November election and since last year's dramatic increase in so-called green-on-blue attacks, when U.S. and NATO soldiers have been killed by the Afghans they are training or working alongside.

There were 45 insider attacks in 2012 that resulted in 62 deaths among coalition forces, including 35 Americans. There has been one attack already in the first 11 days of 2013.

The White House summit included a private Oval Office meeting between Obama, Karzai and Vice President Joe Biden. The trio also attended a private lunch in the Old Family Dining Room.

Karzai Thursday attended meetings with Defense Secretary Leon Panetta and top military brass at the Pentagon, where he was afforded all the pomp and circumstance accorded a head of state: a 21-gun salute, and marching bands and honor guards from the Army, Navy, Air Force, Marines and Coast Guard.

Karzai's relationship with the United States has at times been a rocky one as he has sometimes made critical statements about the allied troop presence in his country. U.S. officials believe he has made those comments out of political expediency to improve his standing with Afghans and show his independence.

Muscle mimic pulls electricity from wet surface

Electricity has been squeezed from a damp surface for the first time, thanks to a polymer film that curls up and moves – a bit like an artificial muscle – when exposed to moisture. The film could be used to run small, wearable devices on nothing but sweat, or in remote locations where conventional electricity sources aren't available.

When a dry polymer absorbs water, its molecular structure changes. This can, in principle, be converted into larger-scale movement, and in turn electricity. But previous attempts at creating a material powered by a moisture gradient – the difference in chemical potential energy between a wet region and a dry region - failed to produce a useful level of force.

These unsuccessful tries used a polymer called polypyrrole. Now Robert Langer and colleagues at the Massachusetts Institute of Technology have turned to the material again, embedding chains of it within another material, polyol-borate. This more complex arrangement mimics structures found in muscles as well as in plant tissues that bend in response to changes in humidity.

Flipping film

The result looks like an ordinary piece of thin black plastic, but when placed on a wet surface, something extraordinary happens. As the material absorbs water, its end curls away from the surface and the film becomes unstable, so it flips over. The ends have now dried out, so they are ready to absorb more water, and the whole process repeats itself. This continuous flipping motion lets the film travel across a suitably moist surface unaided.

Langer found that a 0.03-millimetre-thick strip, weighing roughly 25 milligrams, could curl up and lift a load 380 times its mass to a height of 2 millimetres. It was also able to move sideways when carrying a load about 10 times its mass.

To extract energy from this effect, Langer's team added a layer of piezoelectric material – one which produces electricity when squeezed. When this enhanced film, weighing about 100 milligrams, flipped over, it generated an output of 5.6 nanowatts – enough to power a microchip in sleep mode.

Electricity from sweat

Though the output is small, it is proof that electricity can be extracted from a water gradient. "To the extent of our knowledge, we are the first to utilise a water gradient, without a pressure gradient, to generate electricity," says Langer.

Large-scale energy harvesting is unlikely as the size of the device needed would be impractical, but it could be used to power small devices such as environmental monitoring systems in remote locations. "It will be interesting for applications where the amount of energy needed may be low but where access to energy may be difficult," says Peter Fratzl at the Max-Planck Institute of Colloids and Interfaces in Potsdam, Germany, who was not involved in the work.

Another application, Langer suggests, would be to place the film inside the clothing of joggers or athletes. The evaporation of sweat could generate enough electricity to power sensors monitoring blood pressure and heart rate.

American Express cuts 5,400 jobs

American Express said Thursday it would lay off 8.5 per cent of its workforce in 2013, in an effort to contain operating expenses and adapt to customers moving to online and mobile platforms.

The bank said it would eliminate 5,400 jobs, though some of those will be offset by new positions, for a net cut of 4-6 per cent of the 63,500-strong workforce.

The layoffs will span different staff groups and businesses, both in the United States and its international operations, the company said.

The largest reductions will be in AmEx's travel businesses "which operate in an industry that is being fundamentally reinvented as a result of the digital revolution."

It said it took a US$400 million restructuring charge in its fourth quarter to December 31 to cover some of the severance costs of the layoffs.

The restructuring is "designed to contain future operating expenses, adapt parts of the business as more customers transact online or through mobile channels, and provide the resources for additional growth initiatives in the US and internationally," AmEx said.

Excluding the restructuring costs and other special items, the bank said its fourth-quarter net earnings came in at US$1.2 billion, the same as the year-earlier figure.

After the extra costs, net income was at US$637 million, or 56 cents a share, compared with US$1.01 a share for the fourth quarter of 2011.

"Maintaining our momentum in this environment will require us to evolve our business, embrace new technologies, become more efficient and generate resources to invest in the many growth opportunities we've identified," said chief executive Kenneth Chenault.

"For the next two years, our aim is to hold annual operating expense increases to less than three per cent.

"The overall restructuring program will put us in a better position as we seek to deliver strong results for shareholders and to maintain marketing and promotion investments at about nine per cent of revenues."

Dong Ngo/CNET)

LAS VEGAS--Plextor has more news in regard to its SSD development to share at CES 2013, in addition to introducing the M5 Pro Xtreme drive.

The storage vendor unveiled a few new solid-state storage devices today, including the M5M mSATA SSD, a Next Generation Form Factor (NGFF) SSD, and its new embedded multimedia card (eMCC).

The M5M mSATA is a 6Gbps SSD. The new drive has no outer casing and is just one-eighth the size of a standard 2.5-inch drive, designed especially for ultrabooks with limited space. It features the new Marvell 88SS9187 controller, and Toshiba's new 19nm Toggle NAND. The drive comes in 64GB, 128GB, and 256GB capacities, with all of them offering sequential read speeds of up to 540 MBps. The sequential write speeds, however, are 160 MBps, 320 MBps, and 430 MBps respectively. The drive's mean time between failures is rated at 2.4 million hours, and it will be available during the first quarter of the year.

As the name suggests, the NGFF SSD has a new shape and size; it's even smaller than the mSATA. With typical measurements of just 51x30x5mm (about the size of a small thumbdrive, but thinner), it's designed for use in smartphones and mobile devices. The drive is available in 128GB and 256GB capacities with sequential read and write speeds of 700MBps and 550MBps, respectively. The new NGFF SSD will also be available in the first quarter.

And finally, the eMMC is just about the size of a small fingernail. The drive is available only in embedded applications such as digital cameras, smartphones, and
tablets. According to Plextor, an eMMC is a standardized method for bundling the controller into the flash die, and now includes features such as secure erase, TRIM, and high-priority interrupt. It offers up to 128GB of storage space with high performance. Expect devices with the new Plextor eMMC in the second quarter of the year.

On top of this, Plextor also showed off its 2.5-inch standard enterprise SSDs that use Single Level Cell (SLC) NAND and Multiple Level Cell (MLC) NAND. Plextor says the SLC drive focuses on high endurance to offer extreme reliability. The MLC drive features power protection that guards against data loss in case of power outages, and is also capable of withstanding an extreme range of temperatures. The new enterprise SSDs are available now.

How "Cheating" Slime Mold Escapes Death

Cheaters do prosper—at least if you're a slime mold, a new study says.

The slime mold Dictyostelium discoideum, found in most warm parts of the world, has an unusual life cycle. Most of the time Dicytostelium cells are "happy" single cells that hang out and eat bacteria, according to study leader Lorenzo Santorelli of the University of Oxford, who conducted the research while at Rice University and Baylor College of Medicine.

But sometimes, when food is scarce, different strains of Dictyostelium, including a mutated strain, form a mobile, multicellular organism called a "slug." This cluster then sprouts a stalk called a fruiting body, which produces spores that disperse into new slime molds. (Also see "Slime Has Memory but No Brain.")

For a slug to produce a stalk, however, nearly 20 percent of its cells must die—essentially sacrificing themselves to pass on their genes. (Get a genetics overview.) The remaining 80 percent live on and become spores.

Now, for the first time, Santorelli and colleagues have figured out the mechanism by which the mutated strain is able to survive in higher numbers than the others.

It suppresses normal cells from becoming spores, thereby forcing more of these cells to sacrifice themselves for the stalk and die. Meanwhile, more cells in the mutated strain become spores—and thus avoid dying as stalk cells. In other words, more than the "fair share" of cheater cells see another day.

Cheating Cells Surprisingly Healthy

To make the discovery, the team mixed the cheater strain with normal strains and observed that more cells in the cheater strain live on. (See "Smart Slime, Ovulating Strippers Among 2008 Ig Nobels.")

On one hand, this isn't all that surprising, Santorelli noted: "Cooperation is always under attack in any organism—trying to get something for [yourself], it's just nature."

But what is striking, he said, is that usually cheaters eventually cause the entire cooperative system to collapse. Not so in Dictyostelium—somehow it's evolved a way to keep everything running smoothly, said Santorelli, whose study was recently published in the journal BMC Evolutionary Biology.

What's more, cheaters are usually weaker than cooperative individuals. But not in Dictyostelium cheaters, which appear to be quite healthy.

Santorelli wants to find out how the cheater strain is so successful. And, just maybe, the lowly slime mold could unravel the evolutionary and genetic basis for cooperation, he added.

"Slime mold is an amazing organism."

Jodi Arias: 'No Jury Will Convict Me' for Murder

The jury in the Jodi Arias murder trial watched a television interview today in which Arias said "no jury will convict me" for killing her ex-boyfriend, Travis Alexander.

Arias added that she could never imagine committing such a violent act as killing Alexander.

"I understand all the evidence is really compelling," she said in the interview. "In a nutshell, two people came in and killed Travis. I've never even shot a gun. That's heinous. I can't imagine slitting anyone's throat."

She went on to tell the interviewer, "No jury will convict me and you can mark my words on that. ... I am innocent."

Arias made the statements to the television show "Inside Edition" after she was indicted for murdering Alexander. Months later, she would confess to killing him in his Mesa, Ariz., home and say it was in self-defense.

The tape was played on the fifth day of testimony in Arias' trial, in which police allege that she carried out the murder with such brutal force that she stabbed Alexander 27 times, slashed his throat from ear to ear, and shot him in the head.

Arias, now 32, has claimed Alexander was a controlling and abusive "sexual deviant" who she was forced to kill in self-defense.

She could face the death penalty if convicted of Alexander's murder.

The defense petitioned the court to declare a mistrial at the end of testimony today, but the request was denied by Judge Sherry Stephens. Arias' attorneys claimed that testimony presented by Det. Esteban Flores about whether Arias shot Alexander first or at the end of the attack was different from his earlier testimony and, therefore, affected whether Arias was "especially cruel" during the killing -- but Stephens denied that it had any effect.

The jury also watched as dozens of photos of blood-spattered walls, flooring, stained carpets and blood smeared sink were explained in detail by a forensic analyst from the Mesa Police Department, who noted that on many of the stains water had been mixed with the blood and diluted it.

The prosecution has alleged that Arias tried to wash away the evidence of the killing with water.

Prosecutors spent much of today and Wednesday using Arias' recorded statements and other testimony to prove that she lied about her relationship with Alexander, where she was when Alexander was killed, and even where she worked as a bartender.

The testimony today suggested that Arias lied to her new boyfriend Ryan Burns about working at a bar called Margaritaville in her hometown of Yreka, Calif.

"Is there any restaurant in Yreka called Margaritaville? Has there ever been?" prosecutor Juan Martinez asked Nathaniel Mendes, a former detective with the Siskiyou County Sheriff's Office in California.

"No, sir," Mendes replied.

Mendes testified that Arias worked at a restaurant called Casa Ramos in Yreka, not a bar called Margaritaville, as she told Burns.

Mendes also went over receipts showing that Arias rented a car the day before she killed Alexander, and noted that she went to a rental outfit 90 miles from her hometown despite two businesses that rented cars in Yreka.

Arias told friends and investigators that she rented a car to go on a road trip to visit Burns, in West Jordan, Utah, on June 3, 2008. She showed up at Burns' house a day late with cuts on her hands, but told Burns that she got lost driving and that the cuts were from broken glass at her Margaritaville bartending job, according to Burns' testimony Wednesday.

The trail of receipts showed that Arias drove from California to Alexander's hometown of Mesa, Ariz., on Tuesday, June 4, 2008.

There, the pair had sex and took sexually graphic photos of one another, according to photographs and the opening statement of Arias' lawyer. Shortly after the tryst, Arias killed Alexander, both sides agree.

Burns testified that Arias never mentioned going to Alexander's house when she arrived at his home in Utah. He said he did not know that Arias and Alexander were still sexually involved, and that she told him they had broken up.

When she arrived at his home 24 hours after killing Alexander, she seemed "normal," he said. The pair kissed and cuddled, and went out with Burns' friends, where she laughed and made conversation.

Prosecutors have played recorded phone conversations between detectives and Arias in the weeks after Alexander's body was found. She could be heard apparently lying multiple times to investigators as they asked about the last time she spoke with Alexander and her trip to Utah.

Flower Power sensor gives everyone green fingers

Niall Firth, technology editor

Are you one of those people that, as soon as they are get a new plant, it is merely a matter of time before the poor thing is just a sad, dried mass of shrivelled leaves? Then a new gadget called Flower Power, unveiled at the International CES trade show in Las Vegas, Nevada yesterday, could be just the thing to help you pretend your fingers really are green.

Developed by Parrot, the French firm that brought us the quad-rotor AR drone, Flower Power is a Bluetooth-enabled stick that you simply shove in the soil with your plant, after having chosen from a list of around 6000 plants which one you are trying not to kill. Sensors in the stick monitor the moisture in the soil, sunlight and whether you need to add any more fertiliser and then send that info via a low-powered version of Bluetooth to the cloud. It's meant to keep on sending data for up to six months before needing a battery change.

The data is analysed and compared with set parameters for the particular type of plant. "We think of it as putting your garden on the internet," says Henri Seydoux, Parrot's CEO. The stick and accompanying Android app are due to be released later this year.

The app displays all the info you need about your plant and flags up areas of concern using colour-coded warning signs, telling you when your beloved bit of flora needs a top up. Graphs show you how they are all faring. In theory, it will leave little excuse for killing that plant that was given to you by your friendly neighbour. In practice, I probably still will. But at least I'll know why this time.

US plays tough with Karzai on Afghan troops

WASHINGTON: US officials plan a mix of hardball negotiating and flattery during a visit by Afghan President Hamid Karzai as President Barack Obama decides how deeply to cut forces in America's longest war.

Karzai will be Obama's first foreign visitor of 2013, with a White House meeting on Friday and State Department dinner on Thursday. The Afghan leader met Wednesday with senators including Republican leader Mitch McConnell.

The talks come as the freshly re-elected Obama charts out plans to pull most of the 68,000 US troops out of Afghanistan. The United States and its allies have already agreed to withdraw combat troops by the end of 2014 but questions remain on a US training and security role after that.

Ben Rhodes, a deputy national security adviser, told reporters Tuesday that Obama sought to prevent Al-Qaeda's return to Afghanistan but would not rule out any ideas including the so-called zero option -- leaving no US troops at all.

Afghanistan watchers in Washington largely saw the hints as a strategy aimed at Karzai, who has had a tumultuous relationship with the Obama administration and is seen as wanting US troops to stay as long as possible.

James Dobbins, a former US diplomat involved in the establishment of Karzai's government in 2001, called the airing of the zero option "a tactical move designed to indicate to Karzai that he has less leverage in this negotiation than he might otherwise."

Dobbins, who considered a Taliban return to power in post-2014 Afghanistan to be possible but unlikely, said troop levels would be determined by how much the United States was willing to spend after more than 11 years of war.

"My view is it's a straight cost/risk ratio. The more you're prepared to pay, the lower your risk; the higher your risk tolerance, the less you can get away with," Dobbins, now an expert at the Rand Corp., said at the Atlantic Council think tank.

News reports have said that some administration officials favour as few as several thousand troops in Afghanistan. Obama's nominees as his next secretary of state and defence secretary, John Kerry and Chuck Hagel, are both seen as supportive of a wide-scale military drawdown.

Marvin Weinbaum of the Middle East Institute said he expected Karzai to press hardest during the White House meetings over what equipment, including air power, the United States would leave or provide Afghan forces.

"He doesn't want the US to pull out completely and he doesn't think the US wants to pull out completely. So that's the meeting point, but he wants to use that as leverage to extract as much as possible," Weinbaum said of Karzai.

Weinbaum said the visit was also aimed at preserving a friendly atmosphere with Karzai, who "is so thin-skinned, if you look at him the wrong way, he thinks you're plotting his demise."

"A lot of these meetings are just to try to keep the chemistry from getting too ugly," said Weinbaum, who believed the plentiful events for Karzai "improve the chances that maybe you can convince him that he's loved."

Tensions rose between the United States and Afghanistan after Karzai won presidential elections in 2009 despite widespread charges of irregularities.

The Obama administration has also pressed Karzai to curb corruption, considered by some US officials to be a major impediment to increasing the government's legitimacy in Afghan eyes.

Opinion polls for several years have shown that the US public is tired of the human and financial cost of the Afghanistan war, initially launched after the September 11, 2001, attacks on the United States. US forces killed Osama bin Laden, the attack's mastermind, in Pakistan in 2011.

But neoconservative analysts Fred and Kimberly Kagan, writing in The Wall Street Journal, said that leaving only a tiny US military presence would impede operations against Al-Qaeda and risk a renewal of ethnic civil war.

"Those who say that Afghanistan can't get any worse than it is today lack both imagination and any knowledge of the country's recent history," they wrote.

Verizon will be late to the HD Voice game

Verizon CEO Lowell McAdam at his keynote presentation.

CNET)

LAS VEGAS--HD Voice has suddenly become a hot topic at this year's Consumer Electronic Show.

The feature, which significantly enhances call quality by improving voice clarity while blocking out background noise, has been long touted by the wireless carriers. Widely available in Europe for years, the U.S. carriers have lagged behind.

T-Mobile said yesterday that HD Voice was now available on select phones in its lineup. PC Mag reported that AT&T was shooting for a launch some time this year. Now Verizon has stepped in, and told CNET that it would offer the feature in 2014.

Verizon will wait until it moves its voice service to the LTE network, according to Mike Haberman. The company plans to have voice-over LTE by the end of the year or early 2014. Currently, data goes over LTE, while the voice call still runs over its 3G network. Haberman said the carrier would support its 3G network through the rest of the decade.

While one of the key benefits of voice-over LTE is a reduction in cost and traffic, Haberman said the company is more interested in the potential services that can be tied into voice with VoLTE.

As for HD Voice, he said Verizon wouldn't offer it until there was a consistent quality of service.

HD Voice continues to travel on a rocky road to the consumer. Sprint Nextel made it a focal point when it launched the feature in the Evo 4G LTE in April, even having actor Keifer Sutherland record a crystal-clear call in a demonstration. But since then, the initiative has sputtered.

Sprint told CNET that it has completed one trial market, and the users can see a few more markets open up in the coming months.

A key problem with HD Voice is the lack of adoption. HD Voice only works if both phones have the feature and are in an area where the network supports it. Miss one component, and the call goes through without any enhanced features.

So even if the Evo 4G LTE supports it, only other users with the same phone can access the feature, and they both have to be in the single trial market. That narrows down the user base considerably.

T-Mobile has said its HD Voice feature will run nationwide through its HSPA+ network. It's also available on three phones: the Samsung Galaxy S III, HTC One S, and Nokia Astound.

Verizon, however, isn't feeling any heat to bring out HD Voice.

Embryonic Sharks Freeze to Avoid Detection

Jane J. Lee

Although shark pups are born with all the equipment they'll ever need to defend themselves and hunt down food, developing embryos still stuck in their egg cases are vulnerable to predators. But a new study finds that even these baby sharks can detect a potential predator, and play possum to avoid being eaten.

Every living thing gives off a weak electrical field. Sharks can sense this with a series of pores—called the ampullae of Lorenzini—on their heads and around their eyes, and some species rely on this electrosensory ability to find food buried in the seafloor. (See pictures of electroreceptive fish.)

Two previous studies on the spotted catshark (Scyliorhinus canicula) and the clearnose skate (Raja eglanteria)—a relative of sharks—found similar freezing behavior in their young. But new research by shark biologist and doctoral student Ryan Kempster at the University of Western Australia has given scientists a more thorough understanding of this behavior.

It all started because Kempster wanted to build a better shark repellent. Since he needed to know how sharks respond to electrical fields, Kempster decided to use embryos. "It's very hard to test this in the field because you need to get repeated responses," he said. And you can't always get the same shark to cooperate multiple times. "But we could use embryos because they're contained within an egg case."

Cloaking Themselves

So Kempster got his hands on 11 brownbanded bamboo shark (Chiloscyllium punctatum) embryos and tested their reactions to the simulated weak electrical field of a predator. (Popular pictures: Bamboo shark swallowed whole—by another shark.)

In a study published today in the journal PLoS One, Kempster and his colleagues report that all of the embryonic bamboo sharks, once they reached later stages of development, reacted to the electrical field by ceasing gill movements (essentially, holding their breath), curling their tails around their bodies, and freezing.

A bamboo shark embryo normally beats its tail to move fresh seawater in and out of its egg case. But that generates odor cues and small water currents that can give away its position. The beating of its gills as it breathes also generates an electrical field that predators can use to find it.

"So it cloaks itself," said neuroecologist Joseph Sisneros, at the University of Washington in Seattle, who was not involved in the study. "[The embryo] shuts down any odor cues, water movement, and its own electrical signal."

Sisneros, who conducted the previous clearnose skate work, is delighted to see that this shark species also reacts to external electrical fields and said it would be great to see whether this is something all shark, skate, and ray embryos do.

Marine biologist Stephen Kajiura, at Florida Atlantic University, is curious to know how well the simulated electrical fields compare to the bamboo shark's natural predators—the experimental field was on the higher end of the range normally given off.

"[But] they did a good job with [the study]," Kajiura said. "They certainly did a more thorough study than anyone else has done."

Electrifying Protection?

In addition to the freezing behavior he recorded in the bamboo shark embryos, Kempster found that the shark pups remembered the electrical field signal when it was presented again within 40 minutes and that they wouldn't respond as strongly to subsequent exposures as they did initially.

This is important for developing shark repellents, he said, since some of them use electrical fields to ward off the animals. "So if you were using a shark repellent, you would need to change the current over a 20- to 30-minute period so the shark doesn't get used to that field."

Kempster envisions using electrical fields to not only keep humans safe but to protect sharks as well. Shark populations have been on the decline for decades, due partly to ending up as bycatch, or accidental catches, in the nets and on the longlines of fishers targeting other animals.

A 2006 study estimated that as much as 70 percent of landings, by weight, in the Spanish surface longline fleet were sharks, while a 2007 report found that eight million sharks are hooked each year off the coast of southern Africa. (Read about the global fisheries crisis in National Geographic magazine.)

"If we can produce something effective, it could be used in the fishing industry to reduce shark bycatch," Kempster said. "In [America] at the moment, they're doing quite a lot of work trying to produce electromagnetic fish hooks." The eventual hope is that if these hooks repel the sharks, they won't accidentally end up on longlines.
