Why It's So Hard to Tell If Your Kid Is Being Bullied

Why It's So Hard to Tell If Your Kid Is Being Bullied

It's National Bullying Prevention Month, and until really recently, I was feeling pretty smug that my kids — ages 4, 6 and 8 — had largely escaped either being a bully or being bullied.

To be a bully, it seemed you had to torment your peers. To be bullied, it seemed you had to be the tormentee. But what I've learned is that the definitions are not always so clear-cut. Moreover, they're almost beside the point: if a kid — or his mom — feels like another child is being mean for the sake of being mean, it's time to pay attention.

A few weeks ago, my son, a third-grader, came home complaining about the boy who sat next to him in class. They'd been paired to work on a project, and the boy had yelled at him, my son said.

“Really?” I said, surprised. “In the middle of class?”

Yes, insisted my son. They'd disagreed, and the boy delivered a verbal dressing-down, very loudly. My son was mortified.

He'd told his classmate not to yell at him. Or so he said. Although he has no problem telling his squabbling sisters where to get off, he turns meek when it comes to speaking up for himself outside his family circle. And aren't meek kids a bully's prey of choice?

MORE: What You Need to Know About Bullying

In many school districts across the country, children learn from kindergarten onward about standing up to bullies. In my children's schools in Seattle, there are anti-bullying posters on the walls and anti-bullying speakers who address the kids in schoolwide assemblies. Mothers tote their babies into classrooms as part of a campaign to instill empathy in schoolchildren. Kids bring home brochures in their backpacks.

Traditionally, bullying evokes images of a hulking kid roughing up a beanpole in the boys' bathroom. It seems insidious and obvious, like you'd know it when you see it.

Was my son being bullied or was I being a reactionary Mama Bear? I wasn't sure.

I delivered an impromptu pep talk about the importance of being assertive and not letting others treat you badly. Then I promptly forgot all about it.

Until the next week, when he shared that this same boy had humiliated him in the school-bus queue, throwing this barb: You're the worst tablemate in the whole world. It would almost have been laughable had I not heard the hurt in my son's voice.

Was this bullying? It had happened twice, so there was repetition, which is a critical element of bullying.

Megan Moreno, an assistant professor of pediatrics at University of Wisconsin-Madison and author of a recent “Advice for Patients” column about school bullying published in the Archives of Pediatrics & Adolescent Medicine, says the definition of bullying has evolved.

“In the old days, bullying was getting pushed around on the playground,” she says. “Now we've realized that both verbal and physical abuse have consequences.

“The thing about it,” acknowledges Moreno, “is it's still hard on a day-to-day basis when it's your kid to know what counts.”

She recommends coaching beleaguered children to say something as simple and direct as, Hey, you need to stop it. Resist the temptation as a parent to fling yourself into the conflict; many times, children can resolve the problem on their own. If they can't, of course, it's appropriate to loop in teachers or other adults.

MORE: Why Kids Bully

Earlier this month, TIME put together a mongo package on bullying. In one piece, about re-thinking anti-bullying strategies, I found a clue that seemed to offer a realistic window into my son's experience:

… An emerging area of psychological study is looking at the formation of enemies — the adversarial and antipathetic relationships that are prevalent in classrooms (and, most likely, in the faculty lounge too) ... The problem is that without a clear definition of what constitutes bullying, children who exhibit any type of unfriendly, negative or exclusionary behavior are punished as bullies ...

"It's easy to take it a step further to think of dislike and bullying as the same, but they're not the same," says Melissa Witkow, an assistant professor of psychology at Willamette University and author of a landmark study that found an association between mutual antipathies and a higher level of social development. "As adults, there are people we don't like, but we're not beating them up. We're not harassing them. A lot of adults think that kids should only have positive relationships, but that's not possible."

According to Witkow's interpretation, my son had merely had a couple run-ins with a kid who just didn't like him (this, despite my boy's reigning stature as the 2010-11 winner of his grade's “humanitarian award”). Suck it up, Mom, Witkow seemed to say, and move on.

So I did. But not without first chatting with the boy's mother — actually my husband did that, with far more finesse and studied casualness than I could have mustered — and again reinforcing to my son the importance of standing up for himself.

Without a word from me, his teacher also helped smooth things over, switching up the assigned seating. My son's now got three new seatmates. As far as I know, they haven't proclaimed him the best tablemate in the world — he's got a tendency to be kind of messy — but neither have they dubbed him the worst.

Man wrongly convicted of murder makes boxing debut

Man wrongly convicted of murder makes boxing debut

President Obama rang Bozella (left) last week to wish him luck

A man who spent 26 years in jail for a murder he did not commit has fulfilled his dream by making his professional boxing debut and winning.

Dewey Bozella, now 52, became a prison boxing champion while in New York state's Sing Sing jail.

He was freed in 2009 after his conviction for the the murder of 92-year-old Emma Crapser was overturned.

"I used to lay in my cell and dream about this happening...It was my dream come true," he said after the fight.

Bozella made his debut on the undercard of a world title fight between world light heavyweight champion Bernard Hopkins and Chad Dawson in Los Angeles.

On Thursday President Barack Obama called to wish him luck in his fight with 30-year-old Larry Hopkins, no relation to the champion.

In 1983 Bozella was sentenced to 20 years to life for the murder.

While inside he not only honed his skills as a boxer but also earned two college degrees.

His case was finally taken up by two young New York lawyers, who discovered evidence that several witnesses had lied at his original trial and another man had confessed to the murder.

After being released Bozella said he dreamed of getting the chance to fight just one time as a professional boxer.

Golden Boy Promotions, run by former champion Oscar De La Hoya, agreed to put his bout with Hopkins on the undercard at the 20,000 capacity Staples Center.

When the judges announced he had won a unanimous decision the crowd stood and cheered.

Bozella plans to head back to the town of Newburgh, 60 miles (90km) from New York, and set up a boxing gym.

"I'd like to see kids who are on the street have something productive to do. No more fighting for me," he said.

In the main event Hopkins, himself no spring chicken at 46, lost his title after injuring his shoulder in the second round.

Trees 'boost African crop yields and food security'

Trees 'boost African crop yields and food security'

Tree and crop mixed planting (Image: World Agroforestry Centre)
The nitrogen-fixing roots of certain trees provide valuable nutrients to resource-poor arable land

Planting trees that improve soil quality can help boost crop yields for African farmers, an assessment shows.

Fertiliser tree systems (FTS) also help boost food security and play a role in "climate proofing" the region's arable land, the paper adds.

Researchers from the World Agroforestry Centre say poor soil fertility is one of the main obstacles to improving food production in Africa.

The results appear in the International Journal of Agricultural Sustainability.

"In Africa, it is generally agreed that poor soil management - along with poor water management - is most greatly affecting yields," explained co-author Frank Place, head of the centre's Impact Assessment team.

He said that despite chemical fertilisers having been on the market for more than half a century, farmers appeared reluctant or unable to buy them.

"Therefore, there have been a lot of attempts to bring in other types of nutrients from other systems - such as livestock and plants" he told BBC News.

"We have been working quite a lot on what is broadly referred to as 'fertiliser tree systems'."

Although it has been known for centuries that certain plants, such as legumes, "fix" nitrogen in the soil and boost food crop yields, Dr Place said that the centre's researchers had been looking to develop a more active management approach such as FTS.

In TFS across Africa as a whole, yields are doubling or more in two-thirds of cases”

"Some farms, for example in Zambia, where the farms are larger, it is possible to rest arable land and allow it to lie fallow," he observed.

"But in place such as much of Malawi, where population densities are higher, they cannot afford to fallow their land; so we came up with alternative management systems where they could intercrop the trees with the (maize)."

While the technique is not new, Dr Place said that some of the nitrogen-fixing species used by farmers were probably not the most effective.

For example, farmers in East Africa had been using Cajanus cajan (also known as pigeon pea).

"A lot of the nitrogen was being stored in the trees' seeds; so there was an effort to use other trees that put a greater volume in the soil, such as Gliricidia sepium (one of its common name is mother of cocoa)," he said.

"A really nice thing about G. sepium is that we have been coppicing some of those trees for 20 years and they still continue to grow back vigorously."

What is 'nitrogen-fixing'?

Gliricidia sepium (Image: World Agroforestry Centre)
  • The atmosphere consists of about 80% nitrogen, but plants cannot use it in this form
  • Certain plants, such as legumes, have bacteria growing in their root hairs that convert it into a form that plants can use
  • This form of nitrogen is know as "green manure" and is a nutrient that helps plants, such as food crops, to grow

(Source: World Agroforestry Centre)

However, he acknowledged that there were a number of challenges that had to be addressed in order to maximise yields.

For example, some systems suggested planting rows of trees between rows of crops with mixed results.

"We realised that there were a few management problems with that sort of system - what tended to happen was that there was too much competition between the crops and the trees," Dr Place explained.

"We developed a new management system where the trees were cut very low to the ground at the time you are planting the crop so then there was no light competition.

"The trees go into a dormant state when you cut them like this, so the root system is not competing straight away for the nutrients, so the maize is free to become established.

"The trees only really start to come out out of the dormant phase when the maize is already tall."

Another challenge was to provide enough seeds in order to have mass-scale planting. He said that balancing the provision of high-quality seeds with large local engagement was another hurdle that had to be overcome.

But the rewards in improved yields were noticeable, he added.

"Some of the studies have shown that in TFS across Africa as a whole, yields are doubling or more in two-thirds of cases."

Where the systems were not delivering such good results, Dr Place said that scientists were looking to refine current practices and modify them to suit the local conditions.

'Climate proofing'

As well as helping to boost yields, the use of trees in agriculture has other benefits - such as helping to "climate proof" agriculture land.

One example, Dr Place said, was the use of Faidherbia albida (common names include winter thorn and apple-ring acacia) in West African arable landscapes.

"It has a deep penetrating tap root, and it can secure a good water supply even in dry years," he explained.

"Generally speaking, tree roots do go much deeper than crop roots, so it is recycling nutrients and water from deeper reaches.

"There are also studies showing that these roots act as conduits and bring up water to surface root systems (such as those belonging to crops)."

The editor-in-chief of the International Journal of Agricultural Sustainability, Professor Jules Pretty from Essex University in , said the study illustrated that there was a growing movement of agricultural innovations across Africa that were increasing yields and at the same time improving the environment.

"Trees and shrubs in agricultural systems seem to break some of the rules of agriculture - in this case, farmers are using shrubs to create a diverse rotation pattern rather than year-on-year maize," he told BBC News.

"The trees fix nitrogen and improve the soil; the leaves can be fed to livestock; the crops then benefit greatly in subsequent years."

The woman had some rare genetic changes

The entire DNA sequence of a woman who lived to 115 has been pieced together by scientists.

The woman, who was the oldest in the world at the time of her death, had the mind of someone decades younger and no signs of dementia, say Dutch experts.

The study, reported at a scientific conference in Canada, suggests she had genes that protected against dementia.

Further work could give clues to why some people are born with genes for a long life, says a UK scientist.

It is more than 10 years since the first draft of the human genetic code was revealed.

Sequencing the genome of the world's oldest woman is an important starting point ”

Dr Jeffrey Barrett Sanger Centre

Since then, perhaps a few hundred individuals have had their genes mapped in full, as the technology to "read" DNA gets better and cheaper.

The woman, whose identity is being kept secret, and is known only as W115, is the oldest person to have her genes mapped.

She donated her body to medical science, allowing doctors to study her brain and other organs, as well as her entire genetic code.

Dr Henne Holstege, of the Department of Clinical Genetics at the VU University Medical Center in Amsterdam, says she appeared to have some rare genetic changes in her DNA.

It is not yet clear what role they carry out, but it appears there is something in her genes that protects against dementia and other diseases of later life.

Dr Holstege told the BBC: "We know that she's special, we know that her brain had absolutely no signs of Alzheimer's.

"There must be something in her body that is protective against dementia.

"We think that there are genes that may ensure a long life and be protective against Alzheimer's."

Proof of principle

W115 was born prematurely and was not expected to survive.

But she lived a long and healthy life, and entered a care home at the age of 105.

She eventually died from a stomach tumour, having been treated for breast cancer at the age of 100.

A test of her mental skills at the age of 113 showed she had the performance of a woman aged 60-75 years.

At post-mortem examination, doctors found no evidence of dementia or the furring of the arteries seen in heart disease.

They are making her gene sequence available to other researchers, to further the cause of science.

The work, which has yet to be published, was presented at the American Society of Human Genetics annual meeting in Montreal, Canada.

Commenting on the study, Dr Jeffrey Barrett, of the Sanger Centre in Cambridge, UK, said it was an important proof of principle.

He told the BBC: "Sequencing the genome of the world's oldest woman is an important starting point to understand how DNA variation relates to the process of having a long, healthy life.

"But in order to really understand the underlying biology of living a long, healthy life, we will need to look at the DNA sequence of hundreds or thousands of people."

1-in-7 (~15%) not fit to be in Army

Army leaders have been telling us for years that the post-9/11 wars have been chewing up their armor and other weapons. This week, the service's top docs made clear the same thing is happening to the troops, although much of it isn't combat-related.

Some 15% of active-duty troops – that's one out of seven – is undeployable for medical reasons, Lieut. General Eric Schoomaker, the Army surgeon general, told the annual Association of the U.S. Army gathering in Washington. "This has begun to erode the readiness of the Army as a whole," Schoomaker said. "It's an issue the leadership of the Army has identified as a major problem for us." The numbers are even worse in reserve units, where roughly one of every three troops is non-deployable.

"If we don't get our arms around the non-deployable population -- and the biggest population is the medically non-deployable population -- we're going to have a significant problem manning our units to get them to go downrange," Brigadier General Brian Lein, the chief medical officer of U.S. Forces Command, said. "The soldier is the center of our formations, so if the soldier is not ready to go, then the unit is not ready to go." The problem, the Army docs say, is only going to get worse as the Army shrinks in the coming years.

The biggest medical issue is injuries to muscles and bones, which put the equivalent of 68,000 soldiers a year on the sidelines. One of every four recruits coming into the Army has low iron and poor bone density, and recruits today have the highest body mass index in Army history – all of which makes such injuries more likely. The Army is developing new fitness routines and deploying healthier diets to help deal with the issue.

Mandela: His 8 Lessons of Leadership

Mandela: His 8 Lessons of Leadership

By Richard Stengel

Though Mandela has retreated from the public stage, the 90-year-old still speaks out, as he did in condemning Zimbabwe's Mugabe.
Hans Gedda / Sygma / Corbis

Nelson Mandela has always felt most at ease around children, and in some ways his greatest deprivation was that he spent 27 years without hearing a baby cry or holding a child's hand. Last month, when I visited Mandela in Johannesburg — a frailer, foggier Mandela than the one I used to know — his first instinct was to spread his arms to my two boys. Within seconds they were hugging the friendly old man who asked them what sports they liked to play and what they'd had for breakfast. While we talked, he held my son Gabriel, whose complicated middle name is Rolihlahla, Nelson Mandela's real first name. He told Gabriel the story of that name, how in Xhosa it translates as "pulling down the branch of a tree" but that its real meaning is "troublemaker."

As he celebrates his 90th birthday next week, Nelson Mandela has made enough trouble for several lifetimes. He liberated a country from a system of violent prejudice and helped unite white and black, oppressor and oppressed, in a way that had never been done before. In the 1990s I worked with Mandela for almost two years on his autobiography, Long Walk to Freedom. After all that time spent in his company, I felt a terrible sense of withdrawal when the book was done; it was like the sun going out of one's life. We have seen each other occasionally over the years, but I wanted to make what might be a final visit and have my sons meet him one more time.

I also wanted to talk to him about leadership. Mandela is the closest thing the world has to a secular saint, but he would be the first to admit that he is something far more pedestrian: a politician. He overthrew apartheid and created a nonracial democratic South Africa by knowing precisely when and how to transition between his roles as warrior, martyr, diplomat and statesman. Uncomfortable with abstract philosophical concepts, he would often say to me that an issue "was not a question of principle; it was a question of tactics." He is a master tactician.

Mandela is no longer comfortable with inquiries or favors. He's fearful that he may not be able to summon what people expect when they visit a living deity, and vain enough to care that they not think him diminished. But the world has never needed Mandela's gifts — as a tactician, as an activist and, yes, as a politician — more, as he showed again in London on June 25, when he rose to condemn the savagery of Zimbabwe's Robert Mugabe. As we enter the main stretch of a historic presidential campaign in America, there is much that he can teach the two candidates. I've always thought of what you are about to read as Madiba's Rules (Madiba, his clan name, is what everyone close to him calls him), and they are cobbled together from our conversations old and new and from observing him up close and from afar. They are mostly practical. Many of them stem directly from his personal experience. All of them are calibrated to cause the best kind of trouble: the trouble that forces us to ask how we can make the world a better place.

No. 1
Courage is not the absence of fear — it's inspiring others to move beyond it
In 1994, during the presidential-election campaign, Mandela got on a tiny propeller plane to fly down to the killing fields of Natal and give a speech to his Zulu supporters. I agreed to meet him at the airport, where we would continue our work after his speech. When the plane was 20 minutes from landing, one of its engines failed. Some on the plane began to panic. The only thing that calmed them was looking at Mandela, who quietly read his newspaper as if he were a commuter on his morning train to the office. The airport prepared for an emergency landing, and the pilot managed to land the plane safely. When Mandela and I got in the backseat of his bulletproof BMW that would take us to the rally, he turned to me and said, "Man, I was terrified up there!"

Mandela was often afraid during his time underground, during the Rivonia trial that led to his imprisonment, during his time on Robben Island. "Of course I was afraid!" he would tell me later. It would have been irrational, he suggested, not to be. "I can't pretend that I'm brave and that I can beat the whole world." But as a leader, you cannot let people know. "You must put up a front."

And that's precisely what he learned to do: pretend and, through the act of appearing fearless, inspire others. It was a pantomime Mandela perfected on Robben Island, where there was much to fear. Prisoners who were with him said watching Mandela walk across the courtyard, upright and proud, was enough to keep them going for days. He knew that he was a model for others, and that gave him the strength to triumph over his own fear.

No. 2
Lead from the front — but don't leave your base behind
Mandela is cagey. in 1985 he was operated on for an enlarged prostate. When he was returned to prison, he was separated from his colleagues and friends for the first time in 21 years. They protested. But as his longtime friend Ahmed Kathrada recalls, he said to them, "Wait a minute, chaps. Some good may come of this."

The good that came of it was that Mandela on his own launched negotiations with the apartheid government. This was anathema to the African National Congress (ANC). After decades of saying "prisoners cannot negotiate" and after advocating an armed struggle that would bring the government to its knees, he decided that the time was right to begin to talk to his oppressors.

When he initiated his negotiations with the government in 1985, there were many who thought he had lost it. "We thought he was selling out," says Cyril Ramaphosa, then the powerful and fiery leader of the National Union of Mineworkers. "I went to see him to tell him, What are you doing? It was an unbelievable initiative. He took a massive risk."

Mandela launched a campaign to persuade the ANC that his was the correct course. His reputation was on the line. He went to each of his comrades in prison, Kathrada remembers, and explained what he was doing. Slowly and deliberately, he brought them along. "You take your support base along with you," says Ramaphosa, who was secretary-general of the ANC and is now a business mogul. "Once you arrive at the beachhead, then you allow the people to move on. He's not a bubble-gum leader — chew it now and throw it away."

For Mandela, refusing to negotiate was about tactics, not principles. Throughout his life, he has always made that distinction. His unwavering principle — the overthrow of apartheid and the achievement of one man, one vote — was immutable, but almost anything that helped him get to that goal he regarded as a tactic. He is the most pragmatic of idealists.

"He's a historical man," says Ramaphosa. "He was thinking way ahead of us. He has posterity in mind: How will they view what we've done?" Prison gave him the ability to take the long view. It had to; there was no other view possible. He was thinking in terms of not days and weeks but decades. He knew history was on his side, that the result was inevitable; it was just a question of how soon and how it would be achieved. "Things will be better in the long run," he sometimes said. He always played for the long run.

No. 3
Lead from the back — and let others believe they are in front
Mandela loved to reminisce about his boyhood and his lazy afternoons herding cattle. "You know," he would say, "you can only lead them from behind." He would then raise his eyebrows to make sure I got the analogy.

As a boy, Mandela was greatly influenced by Jongintaba, the tribal king who raised him. When Jongintaba had meetings of his court, the men gathered in a circle, and only after all had spoken did the king begin to speak. The chief's job, Mandela said, was not to tell people what to do but to form a consensus. "Don't enter the debate too early," he used to say.

During the time I worked with Mandela, he often called meetings of his kitchen cabinet at his home in Houghton, a lovely old suburb of Johannesburg. He would gather half a dozen men, Ramaphosa, Thabo Mbeki (who is now the South African President) and others around the dining-room table or sometimes in a circle in his driveway. Some of his colleagues would shout at him — to move faster, to be more radical — and Mandela would simply listen. When he finally did speak at those meetings, he slowly and methodically summarized everyone's points of view and then unfurled his own thoughts, subtly steering the decision in the direction he wanted without imposing it. The trick of leadership is allowing yourself to be led too. "It is wise," he said, "to persuade people to do things and make them think it was their own idea."

No. 4
Know your enemy — and learn about his favorite sport
As far back as the 1960s, Mandela began studying Afrikaans, the language of the white South Africans who created apartheid. His comrades in the ANC teased him about it, but he wanted to understand the Afrikaner's worldview; he knew that one day he would be fighting them or negotiating with them, and either way, his destiny was tied to theirs.

This was strategic in two senses: by speaking his opponents' language, he might understand their strengths and weaknesses and formulate tactics accordingly. But he would also be ingratiating himself with his enemy. Everyone from ordinary jailers to P.W. Botha was impressed by Mandela's willingness to speak Afrikaans and his knowledge of Afrikaner history. He even brushed up on his knowledge of rugby, the Afrikaners' beloved sport, so he would be able to compare notes on teams and players.

Mandela understood that blacks and Afrikaners had something fundamental in common: Afrikaners believed themselves to be Africans as deeply as blacks did. He knew, too, that Afrikaners had been the victims of prejudice themselves: the British government and the white English settlers looked down on them. Afrikaners suffered from a cultural inferiority complex almost as much as blacks did.

Mandela was a lawyer, and in prison he helped the warders with their legal problems. They were far less educated and worldly than he, and it was extraordinary to them that a black man was willing and able to help them. These were "the most ruthless and brutal of the apartheid regime's characters," says Allister Sparks, the great South African historian, and he "realized that even the worst and crudest could be negotiated with."

No. 5
Keep your friends close — and your rivals even closer
Many of the guests Mandela invited to the house he built in Qunu were people whom, he intimated to me, he did not wholly trust. He had them to dinner; he called to consult with them; he flattered them and gave them gifts. Mandela is a man of invincible charm — and he has often used that charm to even greater effect on his rivals than on his allies.

On Robben Island, Mandela would always include in his brain trust men he neither liked nor relied on. One person he became close to was Chris Hani, the fiery chief of staff of the ANC's military wing. There were some who thought Hani was conspiring against Mandela, but Mandela cozied up to him. "It wasn't just Hani," says Ramaphosa. "It was also the big industrialists, the mining families, the opposition. He would pick up the phone and call them on their birthdays. He would go to family funerals. He saw it as an opportunity." When Mandela emerged from prison, he famously included his jailers among his friends and put leaders who had kept him in prison in his first Cabinet. Yet I well knew that he despised some of these men.

There were times he washed his hands of people — and times when, like so many people of great charm, he allowed himself to be charmed. Mandela initially developed a quick rapport with South African President F.W. de Klerk, which is why he later felt so betrayed when De Klerk attacked him in public.

Mandela believed that embracing his rivals was a way of controlling them: they were more dangerous on their own than within his circle of influence. He cherished loyalty, but he was never obsessed by it. After all, he used to say, "people act in their own interest." It was simply a fact of human nature, not a flaw or a defect. The flip side of being an optimist — and he is one — is trusting people too much. But Mandela recognized that the way to deal with those he didn't trust was to neutralize them with charm.

No. 6
Appearances matter — and remember to smile
When Mandela was a poor law student in Johannesburg wearing his one threadbare suit, he was taken to see Walter Sisulu. Sisulu was a real estate agent and a young leader of the ANC. Mandela saw a sophisticated and successful black man whom he could emulate. Sisulu saw the future.

Sisulu once told me that his great quest in the 1950s was to turn the ANC into a mass movement; and then one day, he recalled with a smile, "a mass leader walked into my office." Mandela was tall and handsome, an amateur boxer who carried himself with the regal air of a chief's son. And he had a smile that was like the sun coming out on a cloudy day.

We sometimes forget the historical correlation between leadership and physicality. George Washington was the tallest and probably the strongest man in every room he entered. Size and strength have more to do with DNA than with leadership manuals, but Mandela understood how his appearance could advance his cause. As leader of the ANC's underground military wing, he insisted that he be photographed in the proper fatigues and with a beard, and throughout his career he has been concerned about dressing appropriately for his position. George Bizos, his lawyer, remembers that he first met Mandela at an Indian tailor's shop in the 1950s and that Mandela was the first black South African he had ever seen being fitted for a suit. Now Mandela's uniform is a series of exuberant-print shirts that declare him the joyous grandfather of modern Africa.

When Mandela was running for the presidency in 1994, he knew that symbols mattered as much as substance. He was never a great public speaker, and people often tuned out what he was saying after the first few minutes. But it was the iconography that people understood. When he was on a platform, he would always do the toyi-toyi, the township dance that was an emblem of the struggle. But more important was that dazzling, beatific, all-inclusive smile. For white South Africans, the smile symbolized Mandela's lack of bitterness and suggested that he was sympathetic to them. To black voters, it said, I am the happy warrior, and we will triumph. The ubiquitous ANC election poster was simply his smiling face. "The smile," says Ramaphosa, "was the message."

After he emerged from prison, people would say, over and over, It is amazing that he is not bitter. There are a thousand things Nelson Mandela was bitter about, but he knew that more than anything else, he had to project the exact opposite emotion. He always said, "Forget the past" — but I knew he never did.

No. 7
Nothing is black or white
When we began our series of interviews, I would often ask Mandela questions like this one: When you decided to suspend the armed struggle, was it because you realized you did not have the strength to overthrow the government or because you knew you could win over international opinion by choosing nonviolence? He would then give me a curious glance and say, "Why not both?"

I did start asking smarter questions, but the message was clear: Life is never either/or. Decisions are complex, and there are always competing factors. To look for simple explanations is the bias of the human brain, but it doesn't correspond to reality. Nothing is ever as straightforward as it appears.

Mandela is comfortable with contradiction. As a politician, he was a pragmatist who saw the world as infinitely nuanced. Much of this, I believe, came from living as a black man under an apartheid system that offered a daily regimen of excruciating and debilitating moral choices: Do I defer to the white boss to get the job I want and avoid a punishment? Do I carry my pass?

As a statesman, Mandela was uncommonly loyal to Muammar Gaddafi and Fidel Castro. They had helped the ANC when the U.S. still branded Mandela as a terrorist. When I asked him about Gaddafi and Castro, he suggested that Americans tend to see things in black and white, and he would upbraid me for my lack of nuance. Every problem has many causes. While he was indisputably and clearly against apartheid, the causes of apartheid were complex. They were historical, sociological and psychological. Mandela's calculus was always, What is the end that I seek, and what is the most practical way to get there?

No. 8
Quitting is leading too
In 1993, Mandela asked me if I knew of any countries where the minimum voting age was under 18. I did some research and presented him with a rather undistinguished list: Indonesia, Cuba, Nicaragua, North Korea and Iran. He nodded and uttered his highest praise: "Very good, very good." Two weeks later, Mandela went on South African television and proposed that the voting age be lowered to 14. "He tried to sell us the idea," recalls Ramaphosa, "but he was the only [supporter]. And he had to face the reality that it would not win the day. He accepted it with great humility. He doesn't sulk. That was also a lesson in leadership."

Knowing how to abandon a failed idea, task or relationship is often the most difficult kind of decision a leader has to make. In many ways, Mandela's greatest legacy as President of South Africa is the way he chose to leave it. When he was elected in 1994, Mandela probably could have pressed to be President for life — and there were many who felt that in return for his years in prison, that was the least South Africa could do.

In the history of Africa, there have been only a handful of democratically elected leaders who willingly stood down from office. Mandela was determined to set a precedent for all who followed him — not only in South Africa but across the rest of the continent. He would be the anti-Mugabe, the man who gave birth to his country and refused to hold it hostage. "His job was to set the course," says Ramaphosa, "not to steer the ship." He knows that leaders lead as much by what they choose not to do as what they do.

Ultimately, the key to understanding Mandela is those 27 years in prison. The man who walked onto Robben Island in 1964 was emotional, headstrong, easily stung. The man who emerged was balanced and disciplined. He is not and never has been introspective. I often asked him how the man who emerged from prison differed from the willful young man who had entered it. He hated this question. Finally, in exasperation one day, he said, "I came out mature." There is nothing so rare — or so valuable — as a mature man. Happy birthday, Madiba.

TV Weekend: The Walking Dead Has Legs

TV Weekend: The Walking Dead Has Legs

Posted by

By the end of its short first season, I was ready to put The Walking Dead on my list of "almost" shows: those series that had the potential to be great, but which for lack of execution or desire never actually got there. It had well-regarded source material (I haven't myself read the Robert Kirkman graphic novels)* and a terrific premise: a zombie apocalypse, handled with complete psychological realism. The pilot was breathtaking—sweeping in its visuals, economical in its dialogue and unstinting in its dedication to show how actual people would respond to the potential grisly end of human life.

The rest of the season delivered on plot, but the writing faltered, hampered by often-clichĂ©d dialogue, stock characters and haphazard-seeming narrative diversions. There were strong sequences—the final, hope-crushing interlude at the CDC was effective, if rushed—but what began with the potential to be a great series (on a par with other AMC and HBO dramas) seemed content to be an exciting horror story with just-good-enough storytelling. And the ratings were fantastic, so I wasn't sure it had much incentive to improve.

Going into season 2, there was then the famous friction with the parent network over budget and production issues, and AMC ousted producer, director and showrunner Frank Darabont. Would The Walking Dead itself become a kind of TV zombie, kept alive (on a smaller budget) with stopgap producers, mediocre scripts and the momentum of a devoted audience without many good options for genre horror on TV?

Darabont left during production, so it will really take the season to find the answers. But I've seen the first two episodes, and I have some good news about a show that's mostly about bad news: The Walking Dead is starting season 2 much more strongly than it ended season 1.

I can't really get into much plot detail without running into spoilers. But as a very general setup: the show picks up almost precisely where it left off. The caravan of zombieism survivors has left the CDC and is moving on down the highway in search of another haven. What happens next is—well, harrowing and thrilling, and involves zombies. But maybe most important is that what happens next is not too much. Maybe because it has a full season to play with, the show slows down, focusing on a couple of acts of violence and their very painful (physical and moral) aftereffects.

It had always seemed really clear that no one was safe on The Walking Dead, but these first episodes make it undeniable—to the point of being tough for me to watch, and I see a lot of TV violence. And they do it with compelling action sequences and lean, emotional dialogue: the whole show feels more pared-down and focused. And star Andrew Lincoln benefits from this in particular, embodying a man trying to bear up under pressure past the point of exhaustion.

There are still big issues baked into The Walking Dead: the group vs. the individual, whether extremity brings out the best or worst in the survivors, whether the living are more dangerous than the walking dead. And it should: what separates a great monster story from a sheer pulp entertainment is that it's about something besides horror. But for these two episodes, at least, The Walking Dead probes the issues through action, more than talk, and it's better for it.

Check back here Monday at time.com, where Nate Rawlings is going to do weekly recaps of the show. (I'll check in on it from time to time too, but I'm doing Boardwalk Empire the same night and don't want to give either short shrift.) I'm not ready to proclaim The Walking Dead's problems solved yet, but this new beginning is reason for hope. And after what it has to show you, you'll need some.

Migrants ride 'the Beast' from Mexico to the US

Migrants ride 'the Beast' from Mexico to the US

Mexican actor Gael Garcia Bernal has spoken with migrants from across Central America who are trying to reach the United States

Every year, thousands of undocumented migrants cling to the wagons of "the Beast", a freight train that runs from southern Mexico to the US-Mexican border, braving bandits, immigration officials and the elements to reach "El Norte".

The BBC spoke to two who survived the perilous journey and made it to California.

Frida Hinojosa, Mexican migrant

Frida Hinojosa Frida Hinojosa says she would make the journey again if she had to

To get to Los Angeles, California, where she has lived since crossing the US-Mexican border without documents five years ago, Frida Hinojosa left her tin shack in Southern Mexico ready to board the "Train of Death".

"It was a fearful journey, filled with uncertainties. Those were probably the worst days of my life," she says.

By train, Ms Hinojosa travelled about 1,100km (684 miles) from the city of Tapachulas, near the border between Guatemala and Mexico, all the way to Mexico City.

"Los garroteros [people armed with garrottes] were running from coach to coach in the middle of the night, asking for money," she says. "They said that even though the train was free and we had not paid for a proper ticket, we had to pay them to be able to ride. And if you had nothing, they would just abuse you, verbally or physically."

The Beast winds along the Mexican landscape The migrants face bee attacks in the Mexican jungle, dehydration, hunger, and violence

The train, she says, was the only means to get to the North, as she had very little money and no job, and most of those who ride the Beast take between 10 and 15 different trains to cover the distance.

The train is most dangerous for women, many of whom are raped or coerced into performing sexual favours in exchange for protection.

"I was travelling on my own and, as a woman, really bad things happened. It was very sad. I had no money and most of what I got from begging at every train stop I had to give to others, who would then look after me."

"The Beast is a much worse place for women than it is for men," she says.

From Mexico City she continued by bus, stopping in Guadalajara, where she worked to raise money to pay the "coyote" to guide her over the border. She finally reached Tijuana, a border city on Mexico's west coast. On the other side of the fence lay San Diego, California.

Her son joined her in Los Angeles 18 months later. She is now married to a Guatemalan who helped her get the documents that allowed her to remain in the US legally.

"I saw so many sad things," she says.

"I saw a mother whose child died on the train and had to bury him on the Mexican side of the border before continuing her journey. I saw rapes, I saw murders. Knowing that I was doing this for my son gave me strength and hope to keep going. Now he's a grown-up, God bless him, and we are together."

On top of the roof of The Beast Most migrants carry little: a change of clothing, money for bare essentials, maybe a mobile phone

Ms Hinojosa is unemployed, a situation she blames on the US economy. But going back home is not an immediate option for her.

Would she brave the Beast again?

"Of course I would," she replies without hesitation.

"All I got here makes it worth the ordeal. I wouldn't have achieved anything if I had stayed [in Mexico]. Most migrants on the train shared a dream, we are in it together."

Omar, migrant from El Salvador

Omar, from El Salvador Omar failed in his first attempt to reach 'El Norte' and was deported back to El Salvador

Omar, a construction worker who now lives in Los Angeles, started his journey as an undocumented migrant in January 1990.

"Things back then were slightly different, less dangerous perhaps than what they are now," says Omar, who asked the BBC not to use his surname.

He boarded a bus in his native Apopa, a small town in central El Salvador. To reach the US-Mexico border, he first had to travel through Guatemala and Mexico.

A four-day bus ride left him in southern Mexico, ready to board the Train of Death.

"The cargo trains didn't stop, you had to jump on board before it was gone," he says.

"At the beginning it was scary. I let one train go past because I thought I couldn't do it. Then I got used to it. But it's true that your physical abilities determine whether you make it all the way north or you just give up or suffer an accident that can be fatal."

Back then, he recalls, migrants did not have to reach the roof of the carriages for their clandestine journey.

Train guards would open an empty coach for them, with no seats or ventilation, and would seal the doors in between stops.

He travelled for hours jammed into a car with about 200 fellow migrants and suffered severe dehydration.

He had his first glimpse of southern Mexico in the state of Chiapas, where the train made its first stop. He spent the night at a shelters for migrants volunteers had set up along the road.

"I was emotionally drained," he recalls. "I saw people dying falling from the metal stairs of the Beast, some of them mutilated under its wheels. I started thinking that it was harder than I'd been told. I didn't know if I could do it."

Days later, he ran into immigration officers and was deported back to El Salvador.

Migrants on top of "La Bestia" The majority of the Beast riders are Salvadoran, Guatemalan, or Honduran

Six months after that he tried again, asking an acquaintance to guide him in exchange for money.

"Sexual abuses were common, as well as extortions from the authorities who asked for a "mordida" [bribe] to let us go through a checkpoint," he says.

He was mugged and beaten on board the Beast. He also lost all his money: he had given it to a woman he had befriended, thinking that it would be safer with her, but she was also attacked.

To raise the cash to continue, he worked for a month as a cleaner and gardener for a wealthy elderly couple of Russian origin in Tonalá, in the state of Jalisco.

"They wanted to help and let me sleep in their garage during the night," he says.

The memories of the train, he says, are still engraved in his body.

"I've never felt such heat in my life," he recalls.

"Every time I feel extreme heat, all those memories come back. I saw my own death, I felt it and it felt so real while I was riding that train."

Occupy Wall Street protesters arrested in New York

Occupy Wall Street protesters arrested in New York

A number of protesters were arrested in New York on Friday

Related Stories

A number of Wall Street protesters have been arrested in New York during scuffles with police as they marched towards the city's financial district.

The confrontation came after activists averted a showdown with authorities who agreed not to move them from a park.

Demonstrators said officials' plan to clean Zuccotti Park, where they have been based for weeks, had been a ploy to evict them.

The protests against corporate greed have spread to other US cities.

Several demonstrations are reportedly planned this weekend in Canada and Europe, as well as Asia and Africa.

'Be warned'

Fourteen arrests were made on Friday in Lower Manhattan.

At the scene

The protesters were surprised and delighted by the authorities' decision to delay the clean-up, and celebrated by drumming and chanting. Lindsay Anderson, a young New Yorker, told the BBC it was a testament to how effective a non-violent protest can be.

Hip hop magnate Russell Simmons, founder of the Def Jam recording label, told me: "So I'm not going to jail today? I had faith in Mayor Bloomberg to do the right thing." Simmons helped clean up the park overnight with the protesters.

Both he and Ms Anderson say corporations must be held accountable and shouldn't be allowed to donate millions of dollars to Washington politicians.

The wording of the city's statement suggests the reprieve may only be temporary. But for now the protesters feel their movement has spread beyond a mere location - on Saturday they're hoping to see protests against corruption and corporate greed across the world.

In the Colorado city of Denver on Friday, around two dozen demonstrators were detained as police removed their tents in Lincoln Park near the state Capitol.

And 10 Occupy Seattle protesters were held on Thursday when they ignored orders to leave their tents in the city's Westlake Park, said police.

Earlier, New York deputy mayor Cas Holloway released a statement from Zuccotti Park's owners, Brookfield Properties.

"They are postponing their scheduled cleaning of the park, and for the time being withdrawing their request from earlier in the week for police assistance during their cleaning operation," it said.

The statement said Brookfield hoped to "work out an arrangement with the protesters that will ensure the park remains clean, safe [and] available for public use".

An estimated 3,000 protesters streamed into the green space earlier. News of the authorities' climbdown prompted cheers.

The BBC's Laura Trevelyan in New York says it may be that the authorities decided there were just too many people to move.

Activists had sent an email to supporters on Thursday asking them to join the group and "defend the occupation from eviction".

They said on a Facebook page: "Be warned, this is a tactic that [New York City Mayor Michael] Bloomberg has used to shut down protests in the past, and a tactic used recently in similar protests throughout Europe."

Representatives of Brookfield Properties distributed its cleaning notice on Thursday. Some were escorted by police.

The park regulations existed before the protests began but have not been enforced.

They include a prohibition on lying down on the ground or on benches, using sleeping bags or tarps, or the storage of personal property.

New York City councillors joined protesters at a news conference on Thursday evening, calling the effort to move the protesters a "ruse" backed by Mr Bloomberg.

Throughout the park, where protesters have camped since mid-September, big buckets were filled with brooms and mops.

'Offensive odours'

As activists scrubbed the park on Thursday, some questioned the need to clean the space at all.

Bailey Bryant, 28, a Manhattan bank employee who visits the camp after work and on weekends, told Reuters news agency: "We clean up after ourselves. It's not like there's rats and roaches running around the park."

There have been some flashpoints between police and protesters in recent weeks, with hundreds of people arrested this month during a march over the Brooklyn Bridge.

As the number of protesters sleeping in the park has grown, food stalls have sprung up, as well as an infirmary and a library.

But protesters have no toilet facilities of their own and depend on local restaurants near the park.

There have been reports of demonstrators urinating and defecating in the streets.

And residents have complained about lewdness, drug use, harassment and offensive odours from the protesters, Brookfield said.

Earlier this week, Mr Bloomberg said protesters would not be evicted from the park unless they broke the law.

The demonstration began on 17 September with a small group of activists and has swelled to include several thousand people at times, from many walks of life.

Could the US crack high-speed rail?

Could the US crack high-speed rail?


Bullet train, Japan
Bullet trains in Japan are state-of-the-art

A conference in New York is looking at plans to spend $600bn (£380bn) on a national network of high-speed railways, to rival continental Europe's. But how likely is it to happen?

The fastest train in the US pulls slowly out of platform 10 at New York's Penn Station, heading west.

Keeping a leisurely pace on the other side of the Hudson River, the Empire State Building sticks stubbornly to the horizon before eventually receding into the distance. Thirteen minutes later, the Acela Express makes its first stop, in Newark.

This is high-speed rail, American-style.

For many of the passengers packed on board the Acela Express to Washington DC, it is no voyage of discovery but a regular trip.

Train travel beats flying, says hotel executive Michael Shepard. "Getting a plane has become so unattractive, especially for short distances. The train is quicker and takes you right into the city."

Acela passengers rate the service

Acela Express

GOOD:

  • Comfortable
  • Wi-fi
  • Go right into city
  • No security hassle
  • Punctual

BAD:

  • Not really high speed
  • No free drinks
  • More costly than flying
  • No allocated seats
  • Long queues on station concourse

But the 29-year-old New Yorker says the premium you pay for the Express does not represent value for money, with no more legroom than a normal train and not even a complimentary coffee or tea. And he questions whether it's fast enough (2hr 46mins between New York and Washington) to persuade drivers to ditch their cars.

"It's called 'high speed' but is it really? That's the question."

Other passengers say it's a reliable and comfortable service but those with experience of European trains say the American ones are a pale reflection - in terms of frequency, speed and relative luxury.

The Acela is the flagship line of Amtrak, the government-owned company that runs the US railways, a vast network which is reporting a post-war record for numbers of passengers.

Making enough money to cover its operating costs, but little more, it runs along the densely-populated, north-east corridor between Boston and Washington, using trains that briefly reach speeds of 241km/h (150mph) but average about 127km/h (79mph).

That's not fast enough to meet some international definitions of high-speed rail - though a forthcoming upgrade of a 24-mile section of track in New Jersey means the trains will reach speeds of 257km/h (160mph) by 2017.

"This is the first step of a larger programme for Amtrak's vision to get to 220mph (354km/h)," says spokesman Steve Kulm, adding that private firms have shown strong interest in helping to pay for it.

Chart comparing train speeds

Despite the relatively high standard of the service in the north-east corridor, the architectural grandeur of some stations and some scenic journeys, train travel in the land of the motor vehicle is not a mass pursuit.

In a country that owes its economic strength to railways - the first transcontinental railroad linked east and west in the 1860s - most investment in recent decades has been on roads and aviation.

Rail industry experts meeting in New York next month are pushing for a reversal of that trend.

The US High Speed Rail Association (USHSR), which is hosting the event, has set out a highly ambitious, $600bn (£383bn) plan to build a high-speed rail network in four phases by 2030, which it illustrates on its website with an animated map.

Map of the US showing proposed lines A network of high-speed lines across the US by 2030 is the USHSR vision

"This really is the transport system for the 21st Century and there's no reason why we shouldn't build it," says Andy Kunz, president and chief executive officer of USHSR. "In fact we will have to build it. There are no other options.

British rail

Eurostar
  • Normal intercity lines have higher average speeds than the fastest in the US
  • Main high-speed line is Eurostar (above) from London to the Channel Tunnel
  • A £17bn ($27bn) plan for high-speed rail lines linking London, Birmingham, Manchester and Leeds is backed by Prime Minister David Cameron
  • It faces strong opposition from people living in some areas affected

"The oil supply and price is not sustainable and we will not be able to continue to run America with oil at $200 a barrel. If we are going to maintain our prosperity and mobility we have to build this rail system."

Using public and private funds, Mr Kunz argues the network could pay for itself within five or 10 years, because dependency on foreign oil currently costs the US hundreds of billions of dollars annually, and these railways would use cleaner energy sources. They would also generate hundreds of thousands of jobs.

When asked whether it's feasible to implement such a huge project any time soon, he points to two great American feats of engineering - President Lincoln's transcontinental railroad and President Eisenhower's interstate highways built over a period of 35 years a century later.

But there are considerable political and financial hurdles to overcome.

In 2009, President Barack Obama allocated $8bn in his stimulus package towards high-speed rail in 10 areas, but state governors in Florida, Ohio and Wisconsin said "no thanks" and the funds intended for their states were allocated elsewhere.

Union Station, Washington Some of the US railway stations are magnificent

In February, when vice-president Joe Biden proposed a $53bn bill for what he described as the biggest investment in rail since Lincoln, he was derided by one influential Republican as "insane".

For some critics, the problem is not high-speed rail in principle but picking the right projects to invest in, especially when the country is facing a financial crisis and huge spending cuts.

A spokesman for a public policy think-tank, the Reason Foundation, questions the projected passenger figures that enthusiasts put their faith in, and says that beyond the north-east, there are very few places in the US where it could pay its way.

In Europe, where higher fuel prices and denser populations help make high-speed rail more attractive, there has been a frenzy of construction and planning. France and Spain aim to double their networks of bullet trains in the coming decades.

China, which already boasts half the world's high-speed lines, is making similar strides, although an accident that killed 40 people earlier this year sparked a debate about whether the government was moving too fast.

Hitting the buffers

States that said No:

  • Ohio - governor said it would require annual subsidy of $17m
  • Florida - governor predicted a $3bn bill, although local mayors said there was no risk to taxpayers
  • Wisconsin - denounced cash as '"out of control" government spending

The country also operates a magnetic levitation train, which reaches staggering speeds of 430km/h (268mph).

In the US, California could be the first state to get a dedicated high-speed passenger rail system, with work due to begin next year on the first section of a line running the length of the huge state, which would carry 322km/h (200mph) trains.

Congressman Jim Costa believes building the railway will generate nearly 300,000 jobs and then another 450,000 permanent posts after it's built.

But Christian Wolmar, a transport expert based in the UK, has serious doubts.

"In California, the notion that they can build in one fell swoop a high-speed network that runs from Sacramento to San Diego is just too ambitious.

"Why not start with a high-speed line that stretches from one end of the Bay Area to another? Then extend it to LA? Instead they plan this massive high-speed line that goes from one end of the state to another."

Arnold Schwarzenegger Arnold Schwarzenegger looked at Japan's bullet trains when California governor

While the US freight rail system is fantastically successful, the existing passenger service is decades behind Europe, he says, due to low investment and hostility from freight companies, which own most of the track.

"America has not been able to retain anything but a vestige of a passenger railway. Amtrak carries about 30 million [passengers] a year, which in Britain, a much smaller country, is about 10 days' worth of journeys," says Mr Wolmar, who recently returned from the US and wrote about the American railways in his blog.

"They haven't managed to achieve speeds, frequency or fares that would rival cars."

The fact that so many Americans have never boarded a train presents a significant cultural barrier, he adds.

But Mr Kunz disagrees. "People say Americans were born with car keys in their hands and driving is in our DNA - but if you look back to 1922 then 99% of Americans lived in cities and moved around on trains."

From that point on, the oil and motor industries pushed for road projects and American cities were developed with that in mind. But he believes the expansion of light rail and metro systems can help turn urban America into more "walkable communities".

Back on the Acela, the train pulls into its final destination, Union Station, bang on time.

"This is Washington DC. Final stop," says the announcement.

For the American dream of high-speed rail, it could be just the start.

Nanotube yarns twist like muscles

Nanotube yarns twist like muscles

Carbon nanotube artwork
Nanotubes continue to amaze scientists with their mechanical and electronic properties

Yarns made of the tiny straws of carbon called nanotubes have an astounding ability to twist as they contract, scientists have found.

The effect, reported in Science, is similar to the action of muscles found in elephant trunks and squid tentacles.

However, the yarns twist 1,000 times as much as previous "artificial muscles".

The effect, which occurs thanks to a conducting fluid in which the yarns were dipped, could be put to use in motors much thinner than a human hair.

The team of researchers from Australia, the US, Canada and South Korea demonstrated motors that could spin at nearly 600 revolutions per minute, turning a weight 2,000 times heavier than the yarn itself.

Carbon nanotubes have only recently been identified by scientists; they are "straws" made only of atoms of carbon linked together in hexagons. They have remarkable physical properties - being more than 100 times stronger than steel.

Ray Baughman of the University of Texas at Dallas is a renowned researcher into the tubes' properties, and is a co-author of the new research.

"The carbon nanotube yarns comprise invididual nanotubes - untold billions of them - that are about 1/100,000th the diameter of a human hair," he told the podcast of Science magazine.

The yarns were made by pulling sheets of nanotubes from "forests" of the tubes and twisting them to form a coiled structure - much as yarn is made from wool.

They were then dipped in an electrolyte - a fluid containing ions, electrically charged atoms. When a voltage was applied at the ends of the yarns, these ions moved into the fibres, causing them to expand.

Nanotube yarn (U Texas at Dallas)
The nanotube yarns were produced in much the same way as wool yarn is made

Because of their coiled shape, this expansion led to them "doing the twist".

"The torque that we can generate per mass of the yarn is comparable to that of very large electric motors," said Prof Baughman.

"But as you down-size electric motors you dramatically decrease... the torque capabilities per weight, and make the motors very expensive."

He said that motors made from the yarns would find use in what is known as microfluidics, "for chemical 'labs on a chip' that can be used for analysis of chemicals, or for sensing".

"Often you want to control the movement of fluids, you want to pump them from one place to another or turn off one flow and open up another, and the carbon nanotube muscles because of their very small size seem very suitable for this type of application."

Keeping traditional Chinese culture alive

Keeping traditional Chinese culture alive

Lanterns at Taiwanese festival
The Taiwanese are still recognising traditions that have died out on the mainland

Taiwanese people are proud of the way they have preserved traditional Chinese culture. But short-term visitors might wonder if that's little more than boasting.

After all, you don't see people playing Chinese instruments like the two-stringed erhu or the bamboo flute or writing beautiful calligraphy with brushes dipped in water, like you do in Beijing.

In Taiwan, it's more common to see people drinking bottled tea rather than the traditional way - loose leaves steeped in a porcelain cup. Tea served in tiny clay or porcelain teapots is called "old people's tea" here.

The classical courtyard mansions and other ancient buildings are much more common in China's capital than Taiwan's capital.

So other than the 650,000 pieces of Chinese treasures brought over from China and stored at Taipei's National Palace Museum, where is the traditional Chinese culture in Taiwan?

Festivals and feasts

But visitors who stay a little longer will see that centuries-old religious and cultural festivals that have died out on the mainland are still celebrated by millions of Taiwanese.

These include the annual Mazu pilgrimage to honour the Goddess of the Sea. She was worshipped a millennium ago by fishermen in southeastern China, but the Communists banned the practice during the Cultural Revolution. Chinese immigrants brought belief in her to Taiwan in the 17th Century. Statues of her are widely seen in homes and businesses here.

There's also the Burning of Wang Yeh's Boat Festival. Wang Yeh is a plague god worshipped in the old days when mystery illnesses struck communities. During the festival still celebrated in Taiwan, his statue is taken on a days-long parade through towns where he collects people's illnesses and problems.

The festival ends in an all-night party where Wang Yeh is feasted, entertained with music and his boat loaded with fake paper money. The vessel is then set on fire on the beach to symbolise sending him and the people's problems out to sea.

Yayue music survives with the help of Taiwanese musicians

Every September on the birthday of the great sage Confucius, elaborate ceremonies are carefully staged in Taiwan. The one at Taipei's Confucius Temple is attended by the president - something you wouldn't see in China.

Besides festivals, auspicious days on the lunar calendar are also popular, with fake paper money burned on the sidewalks to pay for protection from the gods.

And the cultures of Taiwan's Min Nan and Hakka ethnic groups - though derived from China - are followed here in a way that seems more Taiwanese than Chinese, as these groups' identities are not celebrated on the mainland.

Many of the cultural traditions Taiwan has preserved are related to ancient Chinese music.

Taiwan Direct logo

These include performances of "yayue" or ancient Chinese court music, some 3,000 years old. It died out in China, but was painstakingly researched and revived by professor Chou Chun-yi at Taiwan's Nanhua University.

And while it would be hard to find the gentle and melodic sounds of Nanguan music in China's Fujian province, where it originated, it is still occasionally performed in Taiwan.

Some Taiwanese have also re-created Tang Dynasty dances from 1,300 years ago, though performances are rare.

The problem is even these treasured traditions are not widely accessible in Taiwan, a society more interested in the trendy and modern.

Separate culture

Taiwan's efforts to keep Chinese culture alive have impressed many. Some Taiwanese, however, have tried to avoid linking their cultural traditions with China, despite their Chinese roots.

Chinese culture is the basis of Taiwanese culture”

Emile Sheng Council for Cultural Affairs

There are people, for example, opposed to the mandatory teaching of Confucius texts in schools, favouring building Taiwanese identity instead. Ironically, Confucius' ideals are perhaps more widely taught and practiced here than anywhere else. The influence of Confucianism can be found in the behaviour of Taiwanese people, known for their friendliness and politeness, and in the settlements of its earliest Chinese immigrants.

"Chinese culture is the basis of Taiwanese culture, but because of politics, some people try to deny this. We shouldn't deny our cultural history," said Emile Sheng, minister for the Council for Cultural Affairs, the government department which promotes Taiwan's culture.

Mr Sheng says Taiwanese culture, despite its roots in China, has developed in a uniquely Taiwanese way.

"We have influences from Holland, Portugal, Japan, and the United States, but Chinese culture is indeed our foundation," Mr Sheng says. "Taiwan's culture is diverse, innovative and accepting. It is different from China's culture."

Democratic culture

For example, he says, the island has maintained the use of traditional Chinese writing, while China switched to simplified characters. And its calligraphers have also developed new styles.

Some scholars say Taiwan should become more like Japan South Korea or Vietnam - all countries heavily influenced by Chinese culture in the past, but which developed their own culture. But Mr Sheng believes that's unrealistic.

"Should we then say our culture is not Chinese culture? Then what is Taiwanese culture? Our language, writing system, festivals and celebrations are all Chinese. How can Taiwan become like South Korea or Japan?"

Taiwan's indigenous culture sets it apart from China, but it's only one part of Taiwan's identity, he adds.

Ultimately, what many Taiwanese people cite as the most unique aspect about Taiwan, compared to China, is its democracy.

"Culture is not based on military power or population size," Mr Sheng says. "Chinese tourists who visit Taiwan really like Taiwan's culture, its openness, and politeness. They see the differences."

He believes it's impossible for Taiwan to become identical to China, despite the stepped-up exchanges.

Taiwan might ultimately influence China more.

Already, Taiwan's pop culture is one of its biggest exports to the mainland and ex-pat Chinese communities. Long before relations improved, Chinese people loved Taiwanese singers, like Teresa Teng in the 1970s and 80s. Nowadays, many songs popular in China are from Taiwan.

"Our cultural influence is really great. We should be confident in our culture," said Mr Sheng.

With improved relations with China, Taiwan has recently begun spreading its traditional Chinese culture back to the mainland as well.

China's Fujian province, where the Goddess of the Sea was born, now seeks help from Taiwan to rebuild its Mazu temples and revive Mazu festivals.

The China Conservatory of Music in Beijing and Chinese universities have set up their first yayue ensemble devoted to playing court music, and have invited Professor Chou to be their chief advisor.

But Taiwan also faces challenges maintaining its own people's interest in traditional culture. Many young people cannot speak the language of their ethnicity.

Puppet progress

Glove puppetry used to be the main form of entertainment on the island before televisions or movie theatres, but nowadays it's hard to find children who have seen a puppet show. Puppet masters are struggling to attract fans.

To win over a new audience, puppet masters have made TV puppet shows, and are planning to make 3D puppet movies. And they've added modern props such as motorcycles and computers.

At a performance in a children's playhouse in Taipei, Steven Huang, a fourth generation puppet master, put on a show that held the entire audience's attention.

The stars on stage were the typical martial arts heroes, but had cartoon faces and Sponge Bob joined them.

To Mr Huang, puppetry must be preserved.

"It's inseparable from what is Taiwanese," he says.
