A battery made of wood?

June 19, 2013 ? A sliver of wood coated with tin could make a tiny, long-lasting, efficient and environmentally friendly battery.

But don't try it at home yet -- the components in the battery tested by scientists at the University of Maryland are a thousand times thinner than a piece of paper. Using sodium instead of lithium, as many rechargeable batteries do, makes the battery environmentally benign. Sodium doesn't store energy as efficiently as lithium, so you won't see this battery in your cell phone -- instead, its low cost and common materials would make it ideal to store huge amounts of energy at once, such as solar energy at a power plant.

Existing batteries are often created on stiff bases, which are too brittle to withstand the swelling and shrinking that happens as electrons are stored in and used up from the battery. Liangbing Hu, Teng Li and their team found that wood fibers are supple enough to let their sodium-ion battery last more than 400 charging cycles, which puts it among the longest lasting nanobatteries.

"The inspiration behind the idea comes from the trees," said Hu, an assistant professor of materials science. "Wood fibers that make up a tree once held mineral-rich water, and so are ideal for storing liquid electrolytes, making them not only the base but an active part of the battery."

Lead author Hongli Zhu and other team members noticed that after charging and discharging the battery hundreds of times, the wood ended up wrinkled but intact. Computer models showed that that the wrinkles effectively relax the stress in the battery during charging and recharging, so that the battery can survive many cycles.

"Pushing sodium ions through tin anodes often weaken the tin's connection to its base material," said Li, an associate professor of mechanical engineering. "But the wood fibers are soft enough to serve as a mechanical buffer, and thus can accommodate tin's changes. This is the key to our long-lasting sodium-ion batteries."

The team's research was supported by the University of Maryland and the U.S. National Science Foundation.

Actor James Gandolfini dies in Italy at age 51

LOS ANGELES (AP) ? James Gandolfini's lumbering, brutish mob boss with the tortured psyche will endure as one of TV's indelible characters.

But his portrayal of criminal Tony Soprano in HBO's landmark drama series "The Sopranos" was just one facet of an actor who created a rich legacy of film and stage work in a life cut short.

Gandolfini, 51, who died Wednesday while vacationing in Rome, refused to be bound by his star-making role in the HBO series that brought him three Emmy Awards during its six-season run.

No cause of death was given by HBO and Gandolfini's managers Mark Armstrong and Nancy Sanders in a joint statement confirming his death.

Coroner Antonio Spasola at Rome's Policlinico Umberto I hospital, in the upscale Parioli neighborhood, declined to give a cause of death. Officials at the morgue confirmed that Gandolfini was brought there.

"He was a genius," said "Sopranos" creator David Chase. "Anyone who saw him even in the smallest of his performances knows that. He is one of the greatest actors of this or any time. A great deal of that genius resided in those sad eyes."

HBO called the actor a "special man, a great talent, but more importantly a gentle and loving person who treated everyone, no matter their title or position, with equal respect."

Organizers of the Taormina Film Festival in Sicily were scrambling to put together a tribute to Gandolfini, who had been expected to attend the festival's closing ceremony this weekend and receive an award. Organizers Mario Sesti and Tiziana Rocca said Gandolfini will instead be honored with a tribute "remembering his career and talent."

Sesti and Rocca said they had spoken to Gandolfini hours before his death "and he was very happy to receive this prize and be able to travel to Italy."

Joe Gannascoli, who played Vito Spatafore on the drama series, said he was shocked and heartbroken.

"Fifty-one and leaves a kid ? he was newly married. His son is fatherless now. ... It's way too young," Gannascoli said.

Gandolfini and his wife, Deborah, who were married in 2008, have a daughter, Liliana, born last year, HBO said. The actor and his former wife, Marcy, have a teenage son, Michael.

Gandolfini's performance in "The Sopranos" was his ticket to fame, but he evaded being stereotyped as a mobster after the drama's breathtaking blackout ending in 2007.

In a December 2012 interview with The Associated Press, he was upbeat about the work he was getting post-Tony Soprano.

"I'm much more comfortable doing smaller things," Gandolfini said then. "I like them. I like the way they're shot; they're shot quickly. It's all about the scripts ? that's what it is ? and I'm getting some interesting little scripts."

He played Defense Secretary Leon Panetta in Kathryn Bigelow's Osama bin Laden hunt docudrama "Zero Dark Thirty." He worked with Chase for the '60s period drama "Not Fade Away," in which he played the old-school father of a wannabe rocker. And in Andrew Dominick's crime flick "Killing Them Softly," he played an aged, washed-up hit man.

On Broadway, he garnered a best-actor Tony Award nomination for 2009's "God of Carnage."

Deploying his unsought clout as a star, Gandolfini produced a pair of documentaries for HBO focused on a cause he held dear: veterans affairs.

He was mourned online in a flood of celebrity comments. "The great James Gandolfini passed away today. Only 51. I can't believe it," Bette Midler posted on her Twitter account.

"An extraordinary actor. RIP, Mr. Gandolfini," Robin Williams tweeted.

His final projects included the film "Animal Rescue," directed by Michael R. Roskam and written by Dennis Lehane, which has been shot and is expected to be released next year. He also had agreed to star in a seven-part limited series for HBO, "Criminal Justice," based on a BBC show. He had shot a pilot for an early iteration of the project.

While Tony Soprano was a larger-than-life figure, Gandolfini was exceptionally modest and obsessive ? he described himself as "a 260-pound Woody Allen."

In past interviews, his cast mates had far more glowing descriptions to offer.

"I had the greatest sparring partner in the world, I had Muhammad Ali," said Lorraine Bracco, who, as Tony's psychiatrist Dr. Melfi, went one-on-one with Gandolfini in their penetrating therapy scenes. "He cares what he does, and does it extremely well."

Gandolfini grew up in Park Ridge in New Jersey, the son of a building maintenance chief at a Catholic school and a high school lunch lady.

After earning a degree in communications from Rutgers University, Gandolfini moved to New York, where he worked as a bartender, bouncer and nightclub manager. When he was 25, he joined a friend of a friend in an acting class.

Gandolfini's first big break was a Broadway production of "A Streetcar Named Desire" where he played Steve, one of Stanley Kowalski's poker buddies. His film debut was in Sidney Lumet's "A Stranger Among Us" (1992).

Director Tony Scott, who killed himself in August 2012, had praised Gandolfini's talent for fusing violence with charisma ? which he would perfect in Tony Soprano.

Gandolfini played a tough guy in Scott's 1993 film "True Romance," who beat Patricia Arquette's character to a pulp while offering such jarring, flirtatious banter as, "You got a lot of heart, kid."

Scott called Gandolfini "a unique combination of charming and dangerous."

In his early career, Gandolfini had supporting roles in "Crimson Tide" (1995), "Get Shorty" (1995), "The Juror" (1996), Lumet's "Night Falls on Manhattan" (1997), "She's So Lovely" (1997), "Fallen" (1998) and "A Civil Action" (1998). But it was "True Romance" that piqued the interest of Chase.

In his 2012 AP interview, Gandolfini said he gravitated to acting as a release, a way to get rid of anger. "I don't know what exactly I was angry about," he said.

"I try to avoid certain things and certain kinds of violence at this point," he said last year. "I'm getting older, too. I don't want to be beating people up as much. I don't want to be beating women up and those kinds of things that much anymore."

Obama opens 24-hour trip to Germany

BERLIN (AP) ? President Barack Obama is opening a 24-hour visit to Germany, the culmination of which will be a speech Wednesday at Berlin's iconic Brandenburg Gate.

Obama will also hold meetings with German Chancellor Angela Merkel and other government officials. He arrived in Berlin following a two-day summit of the Group of 8 industrial nations in Northern Ireland.

The president's visit comes nearly 50 years to the day after John F. Kennedy's famous Cold War address in Berlin.

Obama's trip is sure to draw comparisons to his 2008 visit to the once-divided city as a candidate for the White House. He received a rock star welcome, with 200,000 people gathering to hear him deliver remarks at Berlin's Victory Column.

Iran liberals ask: Snub election or take chance?

TEHRAN, Iran (AP) ? In the end, Iran's presidential election may be defined by who doesn't vote.

Arguments over whether to boycott Friday's ballot still boiled over at coffee shops, kitchen tables and on social media among many liberal-leaning Iranians on the eve of the voting. The choice ? once easy for many who turned their back in anger after years of crackdowns ? has been suddenly complicated by an unexpected chance to perhaps wage a bit of payback against Iran's rulers.

The rising fortunes of the lone relative moderate left in the race, former nuclear negotiator Hasan Rowhani, has brought something of a zig-or-zag dilemma for many Iranians who faced down security forces four years ago: Stay away from the polls in a silent protest or jump back into the mix in a system they claim has been disgraced by vote rigging.

Which way the scales tip could set the direction of the election and the fate for Rowhani, a cleric who is many degrees of mildness removed from being an opposition leader. But he is still the only fallback option for moderates in an election that once seemed preordained for a pro-establishment loyalist.

"There is a lot of interesting psychology going on. What is right? Which way to go?" said Salman Shaikh, director of The Brookings Doha Center in Qatar. "This is what it means to be a reformist in Iran these days."

It's also partly a political stock-taking that ties together nearly all the significant themes of the election: the powers of the ruling clerics to limit the choices, the anger over years of pressures to muzzle dissent and the unwavering claims that the last election was stolen in favor of Mahmoud Ahmadinejad, who cannot run for a third consecutive term.

Iran's presidency is a big prize, but not a crown jewel. The president does not set major policies or have the powers to make important social or political openings. That rests with the ruling theocracy and its protectors, led by the immensely powerful Revolutionary Guard

But for liberal-leaning Iranians, upsetting the leadership's apparent plans by electing Rowhani could open more room for reformist voices and mark a rare bit of table-turning after years of punishing reprisals for the 2009 protests, the worst domestic unrest in Iran since the 1979 Islamic Revolution.

"Rowhani raises a lot of interesting questions," said Scott Lucas, an Iranian affairs expert at Britain's Birmingham University. "Among them, of course, is whether he gets Iranians who have rejected the system to then validate the system by voting again."

And there are many other factors at play.

Many Iranians say they are putting ideology aside and want someone who can stabilize the sanctions-battered economy ? one of the roles that does fall within the presidential portfolio. This could boost candidates such as Tehran Mayor Mohammad Bagher Qalibaf, who is seen as a fiscal steady hand.

Also, the rest of the candidates approved to run by election overseers ? from more than 680 hopefuls ? are stacked heavily with pro-establishment figures such a hardliner Saeed Jalili, the current nuclear negotiator. Among those blocked from the ballot was former President Akbar Hashemi Rafsanjani, who is one of the patriarchs of the Islamic Revolution.

The vetting appeared aimed at bringing in a pliant and predictable president after disruptive internal feuds with Ahmadinejad, who upended Iran's political order by trying to challenge the authority of Khamenei. The desire for calm is also fueled by the critical months ahead, which could see the resumption of nuclear talks with the U.S. and other world powers.

But the presumed plans have met an obstacle in the form of Rowhani, who is a close ally of Rafsanjani and is now backed by other reformist leaders who had previously seemed resigned to defeat. In the span 24 hours earlier this week, Rowhani received a major bump when a moderate rival withdrew to consolidate the support. Endorsements from artists, activists and others poured in.

At the final rallies, Rowhani's supporters waved his campaign's signature color purple ? a clear nod to the now-crushed Green Movement and its leader, Mir Hossein Mousavi, who has been under house arrest for more than two years. On Wednesday, the last day of campaigning, thousands of supporters welcomed Rowhani in the northeastern city of Mashhad yelling: "Long live reforms."

Some Rowhani backers also have used the campaign events to chant for the release of Mousavi and other political prisoners, including former parliament speaker Mahdi Karroubi, leading to some arrests and scuffles with police.

Rowhani is far from a radical outsider, though. He led the influential Supreme National Security Council and was given the highly sensitive nuclear envoy role in 2003, a year after Iran's 20-year-old atomic program was revealed.

But he is believed to favor a less confrontational approach with the West and would give a forum for now-sidelined officials such as Rafsanjani and former President Mohammad Khatami, whose reformist terms from 1997-2005 opened unprecedented social and political freedoms. Many are now a memory after clampdowns in the wake of massive protests claiming ballot fraud denied Mousavi victory in the 2009 election.

There are no credible voter polls in Iran, and supporters of each candidate claim their camp is leading. Yet Rowhani seems to be tapping into growing energy and could force a two-way runoff next week with one of the presumed front-runners: Jalili and Qalibaf, a former Revolutionary Guard commander.

Any significant boycott would likely hurt Rowhani the most. And a change of heart to vote by many liberal-leaning Iranians could push Rowhani toward the top.

The worries appeared reflected Thursday in reported comments by Rafsanjani opposing the boycott.

"I urge them to vote," he was quoted as saying by several pro-reform newspapers.

Rowhani's backers, meanwhile, have adopted a motto of "one for 100" ? meaning every reformist should try to encourage 100 people to the polls.

It's not hard, though, to find Iranians promising to snub the election. On some Tehran streets, about every third person planned to stay away.

"Why should I vote?" asked Masoud Abdoli, a 39-year old paramedic. "They have kept opposition leaders under house arrest. They barred Rafsanjani."

Samaneh Gholinejad , a psychology student, said she abandoned politics after the 2009 chaos. "Honesty left the country then," she said.

On social media sites, Iranians have sparred round-the-clock over the boycott.

Supporters often quote Albert Einstein's definition of "insanity" to describe the futility of voting after the allegations of fraud in 2009: "Doing the same thing over and over again and expecting different results." Responses on the other side note that great discoveries would never have occurred if people gave up.

While there are no current signs of street protests resuming, security forces are on high alert. The Revolutionary Guard's volunteer paramilitary force, the Basij, is present in virtually every neighborhood. Authorities have steadily boosted controls on the Internet, attempting recently to close off proxy servers used to bypass Iranian firewalls.

Last month, the U.S. eased restrictions on export of communications equipment to Iranian civilians in an attempt to counter the cyber-crackdowns. There is no evidence, however, of any major U.S. shipments opening new channels for Iranian Internet activists.

In California, meanwhile, Google said it stopped a series of attempts to hack the accounts of tens of thousands of Iranian users with a technique known as phishing.

"The timing and targeting of the campaigns suggest that the attacks are politically motivated," said Eric Grosse, Google's vice president for security engineering, wrote on the company's blog Wednesday. He gave no other details.

Iranians traditionally have shown high interest in voting. The average reported turnout in the past 10 presidential election is more than 67 percent, with officials saying there was 85 percent participation in 2009. There are no independent election observers allowed to verify the numbers, but no major allegations of vote rigging emerged until 2009.

Supreme Leader Ayatollah Ali Khamenei has repeatedly called for a high turnout as a reply to Western governments that have strongly questioned the openness of Iran's elections ? including the process of vetting candidates.

But Khamenei went further in his appeals Wednesday, when he equated voting ? no matter for whom ? as a patriotic act.

"It is possible that some do not want to support the Islamic Republic while seeking to support their own country. They should vote too," said Khamenei.

A prominent political Twitter activist, who goes by the handle Koroush, showed the inner conflicts of many Iranians. He posted a message Thursday saying he will stay home but prays he will regret it.

"I will not vote," he wrote. "But I hope I will be regretful if others vote and Rowhani wins."

Credit Card Debt Begins to Climb as Economy Slowly ... - Bankruptcy

By John Clark

After keeping the plastic in their wallets for the duration of the recession, American consumers have started to make up for lost time by using their credit cards more often, according to a report from the Orlando Sun Sentinel.

//

Sources say American shoppers are on pace to add $47 billion in new credit card debt, according to data compiled by CardHub.com.

Credit Card Debt Begins to Rise as Economy Grows

If consumers do add the expected $47 billion in new credit card debt, that ?would bring the total amount of credit card debt incurred from the beginning of 2011 through the end of 2013 to nearly $130 billion,? according to CardHub?s website.

According to one official, the figures suggest that consumers ?are reverting back to the point where they are living off credit and spending beyond their means.?

This unfortunate trend, sources say, will work ?as long as the economy is doing fairly well,? but as soon as the economy takes another dip south, people who are only making minimum payments on their credit card accounts could feel a great deal of financial pain.

?Now that the economy is doing much better,? said financial expert Andrew Schrage, ?it seems that the average American consumer has become much less focused on paying down debt and is more willing to spend money on discretionary purchases.?

And if this trend continues, more consumers may seek credit card debt relief in Chapter 7 bankruptcy, which is designed to help reduce the burden posed by large amounts of unsecured debt.

Consumers Still Pay Off Billions in Credit Card Debt

Despite the expected $47 billion increase in credit card debt, consumers still paid down nearly $33 billion in debt during the first three months of 2013, according to sources.

But sources believe many of these consumers used holiday bonuses and tax refunds to make these payments, which means that the reduction was contingent on seasonal influxes of cash.

And this actually represented a 7 percent reduction from the amount of debt paid down during the first three months of 2012, according to reports.

This trend concerns many financial analysts, including Schrage, who said he knows ?plenty of people who use their tax refund as a safety net to subsidize their credit card debts.?

But these people ?know in the back of their minds that a big check is coming at the beginning of each year; therefore, they barely keep their heads above water while planning to pay off their balances at tax time,? said Schrage.
