JERUSALEM -- "Shlomi, throw me the ball."

"Assi, it's your turn, pass and dribble."

"Mahmud, great pass. What a basket."

This might sound like a normal basketball game but it's not. The unique endeavor can be best described as an "oasis of coexistence" in Israel where Jews, Muslims and Christians play not only on the same court but in mixed teams.

---

In 2001, American brothers Sean and Brendan Tuohey founded PeacePlayers International with the premise that children who play together can learn to live together.

It seemed quite obvious during my visit to practice that the Tuohey brothers were succeeding. Here on the court at the "Hand in Hand" bilingual school in Jerusalem, Israelis and Palestinians were laughing together, hugging each other and, most importantly, shooting the ball together.

"At first the kids and their parents were hesitant with some kids even crying," says Karen Doubilet, who is the PeacePlayers International's Middle East managing director. "But the transition is very fast, now they jump in joy and hug each other when they meet on and off the court."

'They are like me'
After experiencing so much hatred between Israelis and Palestinians, it was refreshing and exciting to see how naturally these kids reacted and played with each other.

Malak Ayub, 12, is a Muslim girl from the East Jerusalem village of Shoafat.

"Before I came to this program I thought Israelis only wanted to do bad things to us but now I see that they are like me, they want to play together," she said.

One of Malak's best friends is Hadas Prawer, a 14-year-old Israeli from the neighborhood of Mevaseret, which is located west of Jerusalem. I asked Hadas what she tells her friends when they hear she plays with Palestinians.

"I don't care what people think or say, I'm having fun and that's it," she said, before turning around and giving Malak a huge hug.

The traditional Hanukkah 'Sufganiyot' -- the Jewish ball-shaped doughnuts -- were waiting on the sidelines as a reward for the kids' hard work. All the children were wearing T-shirts with the US AID logo on the back, indicating the backing by the US.

"Basketball is huge, especially with the girls," Doubilet added. "Most of these kids don’t have a constructive framework and we give them this activity almost for free. The relationships here will no doubt shape the way Israelis and Palestinians think of each other in the future".

About 550 young people aged from six to 18 enrolled in this program in the past year, bridging communities in Israel like Jaffa, Tamra and Jerusalem where Jews and Muslims live next to each other. 

Haled Sabah is a 20-year-old Palestinian from Shoafat. He joined the program seven years ago and is now one of its coaches.

"I see some racism on both sides but when kids play on the same team they just see each other simply as people," he said. 

A girl who was swept away in the Indian Ocean tsunami seven years ago said Friday that she broke down in tears after tracking down her parents, who had long lost hope of finding her alive.

Wati, 15, showed up earlier this week at a cafe in Meulaboh, a town in Aceh province, saying she had been "adopted" by a woman who forced her to beg in the streets, sometimes until 1 a.m.

---

The teen said she could only remember her grandfather's name, saying it was Ibrahim. Someone at the cafe tracked down a man by that name, and the man — unsure if it was actually his granddaughter — quickly summoned her parents.

"When I saw my mother, I knew it was her. I just knew it," said Wati, who was given that name by the woman who found her. Her original name is Meri Yuranda.

Indonesian state news agency Antara reported on Thursday that the girl was aged eight when she was ripped from her mother's arms by the rushing waters near her home in West Aceh, Indonesia, in December 2004.

It said her mother, Yusniar, was trying to get her and two other children to safety at the time.

The Dec. 26, 2004, tsunami that killed 230,000 people in a dozen nations hit Aceh — closest to the epicenter of the magnitude-9.1 quake that spawned waves 30 feet high — the hardest.

On Friday, The Associated Press said Wati had been kicked out by her "adopted" mother when she stopped bringing in money.

'She has her father's face'
With tens of thousands of bodies never recovered in the province, many people continue to cling to hope of finding lost loved ones, putting up fliers or ads in newspapers.

Reunions, however, are extremely rare and, when they occur, rarely confirmed.

Wati's mother, Yusniar binti Ibrahim Nur, 35, said she did not need a DNA test to prove the girl was hers.

"She has her father's face," she said, adding that she had stopped believing she would ever see her daughter again. "Then I saw the scar over her eye and mole on her hip, and I was even more sure."

Wati and her father had different accounts of what happened on the day of the tsunami.

The girl says she remembers her father putting her into a boat with her sister, who is still missing and presumed dead. The father says that before the family was separated, he put both of his daughters on the roof of their house.

Army prosecutors will be in a tough spot pursuing charges of negligent homicide and involuntary manslaughter against five soldiers in connection with the death of an Asian-American GI whose family and advocates say was the victim of racial taunting, bullying and hazing, according to military law experts.

Pvt. Danny Chen, 19, of New York, was found dead in a guard tower in southern Afghanistan from an apparent self-inflicted gunshot on Oct. 3, according to Army investigators.

Eight soldiers, including an officer, were charged Wednesday in connection with Chen's death, and five were accused of the most serious charges -- involuntary manslaughter to negligent homicide. They “relate to conduct that occurred in the time leading up to his death,” Dave Connolly, chief public affairs officer for Regional Command South in Afghanistan, wrote in an email, declining to provide further detail.

---

Chen, the son of immigrants from southern China, was not depressed but had suffered emotional and physical abuse in the military: He was dragged from his bed and made to crawl while rocks were thrown at his back and was forced to hold liquid in his mouth while doing chin-ups during his two months in Afghanistan, according to accounts from his family, who said they got the information from Army investigators. He also endured racial taunting, including having his last name said in a goat-like voice and other soldiers calling him Jackie Chan, while undergoing training in Georgia, according to letters he wrote to his family and diary entries, said Elizabeth OuYang, New York branch president of OCA, a national civil rights organization serving Asian Pacific Americans.

At the time of his death, Chen had been in the military for seven months; he had deployed to Afghanistan in August.

The negligent homicide and involuntary manslaughter charges in  cases of hazing leading to suicide in the U.S. military appear to be a first, said Grover Baxley, a former member of the U.S. Air Force Judge Advocate General (JAG) Corps, and Hank Nuwer, who has done decades of research on hazing in schools and the military.

“It’s interesting that they’re making -- as I see it -- a leap from hazing to being criminally responsible for a self-inflicted gunshot death,” said Baxley.

He said that in similar cases where the government had gotten hazing convictions, prosecutors could argue in the sentencing phase that hazing was an aggravating factor contributing to death.

“In the Army case, they've taken it a step further and they're actually charging them with criminal responsibility for … Private Chen’s death, and that’s a big distinction,” he said.

Prosecutors still must present their evidence at an “Article 32” hearing – the equivalent of a grand jury in civilian law – after which an investigating officer will determine whether to sustain the charges.

Negligent homicide is defined in military law as "the killing of another person through simple negligence," Baxley said. The US Legal website defines involuntary manslaughter as "manslaughter without any malice or intention," it said.

Under the negligent homicide charge, the government must show that Chen’s death not only resulted from a negligent act by the soldiers but was the “proximate cause” of it, said Baxley, who now has a private practice, JAG Defense.

“That is, that Pvt. Chen’s death was the natural and probable result of the soldiers’ negligent acts,” he wrote in an email. “While I have not seen the evidence in this case … if repeated acts of hazing by numerous individuals are the ‘negligent acts’ that form the basis for the charge, it’s going to be difficult to demonstrate that any one particular soldier’s behavior was the proximate cause of Pvt. Chen’s self-inflicted gunshot wound.”

Greg Rinckey, a former attorney with the U.S. Army JAG Corps, said he agreed with that assessment and noted that the defense would likely try to find evidence, for example, that Chen was fragile, had previously been suicidal or didn’t want to deploy. “They’re going to look at all these things to try and shift the blame from these soldiers are the proximate cause as to, ‘No, the proximate cause was he was predisposed really to suicide,’” he said.

The most serious charges also could be a way of trying to pressure one or more of the defendants into cooperating with prosecutors in exchange for lesser charges or immunity, Rinckey said.

Little is known about the Army's case at this point, but prosecutors "might have a hard time proving this. What could very well happen in a case like this is there could be a plea,” said Rinckey, managing partner of Tully Rinckey PLLC.

“It’s the first person that comes forward is usually the one that gets the sweetest deal,” he added.

A combination of factors – racial, political, a military superior focused on ending hazing – could have also led the Army to impose the rare charges, said Nuwer, an author of several books on the issue.

“Look at the climate in the country. There is a lot of public outcry over the death of Robert Champion at Florida A&M … and it’s kind of outraged the country,” he said, referring to the hazing death of a university band member on Nov. 19. “The other is the hazing has gotten to a point where we’ve now had a death in a fraternity or athletic team or band in a college every year from 1970 to 2011, and sometimes more than that.”

Nuwer, who noted that he was unaware of any similar charges being filed in a civilian court, said that hazing and harassment are rarely aimed at causing death

The soldiers at Combat Outpost Palace in the Panjwa'i district of Kandahar province, where Chen was stationed, may have been trying to push him out of the service or giving him the chance to change his behavior, he said.

“It’s going to be very rare that somebody tries to drive somebody to suicide,” Nuwer said of the hazing. “There’s a theatrical aspect to it. The verbal abuse is often manufactured and escalated to put a lesson into the person, and in effect, the men are often acting for each other. ...

“Then you have a kind of group think that takes over, and a kind of group energy where the whole group together does things to the individual that all of them alone would not have done.”

The military has a "zero-tolerance" policy of hazing, but it still happens, experts say.

“It's a delicate balancing act, because it’s always been in the military and it’s always going to be,” Rinckey said. “It’s very hard for soldiers and sailors that are going to be going into combat together to not have initiation rituals.”

But, he noted: “I think the military is beginning to take hazing very seriously and I think this case is a highlight of that … to how serious they’ll take it, where they’ll charge soldiers with manslaughter and negligent homicide.”

One recent case was that of Lance Cpl. Harry Lew, who was hazed by fellow Marines, according to a U.S. military report on his April 3 death. The military accused three Marines of beating Lew hours before he killed himself and charged them with hazing. They face court martial, The San Jose Mercury News reported.

After a Wednesday morning press conference held in New York by Chen’s family and Asian-American advocates, a senior Pentagon official offered condolences to the soldier’s relatives.

“We treat each other with respect and dignity or we go home -- that’s it,” Navy Capt. John Kirby said, according to a Pentagon news service report. “The tolerance is absolutely zero and the system itself, because it works and works well, is in fact, a deterrent to future behavior.”

“Unfortunately, you’re never going to be 100 percent perfect in this. And there’s going to be those few who want to (flout) what the uniform stands for and what the regulations require … when that happens they’re going to be dealt with.”

Chen's family and advocates are not convinced that his death was a suicide, despite the initial finding that he died of a self-inflicted gunshot wound, and have asked forensic expert Henry Lee to conduct an independent autopsy. Chen's mother, Su Zhen, 49, said she had not wanted her only child to join the Army and at the  press conference said she “could not figure out why they (the soldiers) would do this to him."

OuYang, of the OCA, said her organization does not want the defendants to be allowed to plea bargain.

"It's one thing to charge them with high charges, but it means nothing if they plea bargain to something very low," she said. "... If they are responsible for his death they need to be charged and found guilty of that."

CHRISTCHURCH, New Zealand -- A series of strong earthquakes struck the New Zealand city of Christchurch on Friday, rattling buildings, sending goods tumbling from shelves and prompting terrified holiday shoppers to flee into the streets. There was no tsunami alert issued and the city appeared to have been spared major damage.

Initial reports said one person was injured at a city mall and was taken to a hospital, and four people had to be rescued after being trapped by a rock fall. But there were no immediate reports of serious injuries or widespread damage in the city, which is still recovering from a devastating February earthquake that killed 182 people and destroyed much of the downtown area.

---

The first 5.8-magnitude quake struck Friday afternoon, 16 miles (26 kilometers) north of Christchurch and 2.5 miles (4 kilometers) deep, the U.S. Geological Survey said. Minutes later, a 5.3-magnitude aftershock hit. About an hour after that, the city was shaken by another 5.8-magnitude temblor, the U.S.G.S. said, though New Zealand's geological agency GNS Science recorded that aftershock as a magnitude-6.0. Both aftershocks were less than 3 miles (5 kilometers) deep.

Power was reported out in some neighborhoods, and the Herald said that liquefaction of the ground had occurred in some of the city's eastern suburbs. Sewer lines broke, goods fell from shelves in stores, and large cracks opened in some buildings, the Herald reported.

More coverage of the quake from the New Zealand Herald

About 60 people were treated for minor injuries, including fractures, injuries sustained in falls and people with "emotional difficulties," Christchurch St. John Ambulance operations manager Tony Dowell told The Associated Press.

"We have had no significant injuries reported as a result of the earthquakes today," he said.

Christchurch International Airport was evacuated. A Qantas flight from Sydney was diverted to Wellington, the Herald said. Airport authorities said they hoped to reopen the airport after checking buildings and other facilities for damage. In a tweet at 9:18 p.m. EST, airport officials said that "we hope this wil happen in a few hours."

Newstalk ZB reported that debris had fallen from the Catholic cathedral on Barbados Street.

Radio New Zealand News reported that Warwick Isaacs of the Canterbury Earthquake Recovery Authority said buildings in the city's center were evacuated as a precaution.

"It ... started slow then really got going. It was a big swaying one but not as jolting or as violent as in February," Christchurch resident Rita Langley said.

"It was incredibly violent," one caller told Radio New Zealand.

"All the water in my birdbath slopped out and I could hear everything falling over inside. When I walked inside, the cat streaked out the door, ornaments were all over the floor, contents of the pantry were lying on the floor, a little bit of smashed glass and picture frames lying over."

The shaking was severe in the nearby port town of Lyttelton, the epicenter of the Feb. 22 quake.

"We stayed inside until the shaking stopped. Then most people went out into the street outside," resident Andrew Turner said. "People are emotionally shocked by what happened this afternoon."

The area has recorded more than 7,000 earthquakes since a magnitude-7 quake rocked the city on Sept. 4, 2010. That quake did not cause any deaths.  But the earthquake that hit Christchurch on Feb. 22 killed 181 and caused damage intially estimated at up to $12 billion. It was the second deadliest quake ever recorded in New Zealand; one in 1931 in Hawke's Bay killed 256 people.

The USGS told NBC News that the quakes on Friday could be classified as aftershocks of the February killer.

Christchurch is on the east coast of New Zealand's South Island.

Last updated noon ET Dec. 27:

Italian researchers have resurrected the idea that the Shroud of Turin's mysterious image of a Christlike figure could only have been created by a powerful flash of light — but skeptics still aren't buying it.

Scientists have tussled with believers, and with each other, over the origins of the centuries-old cloth for decades: Many believers think it's the true image of Jesus, left behind miraculously on his burial cloths after his resurrection. Analyses of the Shroud's chemical makeup, as well as radiocarbon dating of fiber samples, have led lots of researchers to conclude that the image was painted onto the cloth during the 14th century. But other researchers, sympathetic to the Shroud's cause, say those tests were faulty.

---

The Italian studies, conducted at the ENEA Research Center in Frascati, addresses a specific question in Shroud science: Could a burst of radiation have created the coloration seen on the linen? The answer is yes, although the results reported in the latest studies aren't a perfect match. So does that mean the Shroud image could only have been created by the flash of a miraculous resurrection? The answer is no, despite what you might read on the Web.

Five years of tests
"Sadly, we have seen many claims spread in the Web made by journalist/bloggers that discuss the content of a paper they never read," lead researcher Paolo Di Lazzaro told me today in an email. "It is obvious that a serious scientific work cannot prove any supernatural action. We have shown that the most advanced technology available today is unable to replicate all the characteristics of the Shroud image. As a consequence, we may argue it appears unlikely a forger may have done this image with technologies available in the Middle Ages or earlier. The probability the Shroud is a medieval fake is really low. In this sense, the Shroud image is still a scientific challenge."

Di Lazzaro and his colleagues based their conclusions on five years of tests, using an ultraviolet laser apparatus and strips of modern-day linen. They blasted the cloth with UV at different power levels, and reported that they "achieved a very superficial Shroud-like coloration of linen yarns in a narrow range of irradiation parameters." The best effect depended on laser pulses lasting less than 50 nanoseconds.

"These processes may have played a role in the generation of the body image on the Shroud of Turin," the researchers report.

They don't go so far as to claim a miracle. But the fact that UV laser blasters didn't exist in the 13th century, let alone in Jesus' day, strongly implies that they suspect something out of the ordinary was going on.

Di Lazzaro told me that the tests were not financed by ENEA, which is a government-sponsored research agency, and were conducted outside working hours. "The research was curiosity-driven, the attempt to replicate an image which is considered 'the impossible image' due to its very peculiar characteristics," he said.

Over the years, Di Lazzaro and his colleagues have published a long list of studies, including peer-reviewed papers (see below). The latest studies were presented at a May conference in Frascati and published in November as an ENEA technical report (with a disclaimer saying that the contents didn't necessarily express ENEA's opinion). But they didn't really get traction until this week, just in time for Christmas, thanks to a series of sensationalized British news reports.

Critiquing Shroud science
Shroud science, also known as sindology, usually percolates outside the scientific mainstream — but every once in a while a sensational claim comes into the public spotlight. Joe Nickell, an investigator for the New York-based Center for Inquiry, has been following sindology for decades. He noted that the Italian research revives a discussion going back to the 1980s, spearheaded by a group called the Shroud of Turin Research Project, or STURP.

"This is really nothing new," Nickell told me today. "This is a supposed vindication of STURP."

Nickell said Di Lazzaro and his colleagues started out with the assumption that the coloration on the Shroud couldn't have been created by applying pigment to the linen — which runs counter to the conclusions drawn by other studies. Starting out with the idea that the human figure shown on the Shroud is an "impossible image" stacks the deck in favor of a miraculous explanation, he said.

"Making the assumption of a miracle is a really, really, really, really, really big assumption," Nickell said. "That it's done in the name of science is just astonishing."

Nickell said the latest findings don't prove much of anything, even though they're dressed up in high-tech tests.

"It is made up of whole cloth," he said. "The pro-Shroud people start with the answer, and then they have to get some scientific evidence to back this up."

Some folks would suggest that the Shroud of Turin is a valuable focus for faith, whether it's real or not. What do you think? How much value is there in studying the Shroud, and how much impact do scientifico-religious debates like this one have on your own thinking? Check out the Web links below, give it some thought, and add your comments.

Update for 4:15 p.m. ET Dec. 22: Di Lazzaro sent a follow-up email calling attention to his group's publications, which I've added below, and he poses this question for Joe Nickell: "Was he (or anybody else) able to reproduce by chemical paint, acid and any other color a depth of coloration which is 0.2 micrometer thick (that is, one-fifth of a thousandth of a millimeter)? We are talking of this, because on the Shroud, the image has a coloration depth so thin that it is impossible to do with any kind of painting. I can quote peer-reviewed papers that show this is the coloration depth of the Shroud image.

"By the way, Nickell will be interested to know that using VUV photons we obtained this shallow coloration thickness," Di Lazzaro wrote.

I'll pass the question along to Nickell, who says he doesn't use email. I suspect the answer could go along two tracks: One is that it's a tough thing to try to reproduce a precise coloration depth under any circumstances. The other is that centuries of wear and tear might have had an effect that's not easily replicated by the contemporary application of pigments or other chemicals. But we'll see what Nickell has to say.

Update for 2:15 p.m. ET Dec. 23: Nickell responded to Di Lazzaro's question, and added a couple of questions of his own:

"Paolo Di Lazzaro claims the Turin 'Shroud' coloration depth is 0.2 micrometers, but surely he does not claim that that was uniformly measured throughout the cloth. The coloration indeed appears to be generally confined to the topmost fibrils (although the face image does show faintly on the back of the cloth). Using a two-part hypothesis I put forward in 1983, Italian chemist Luigi Garlaschelli has produced a replica shroud with such superficial staining. So let me ask Lazzaro a question in turn: Have you been able, using your high-intensity ultraviolet laser technique, to produce a replica shroud yourself? Until you do, shouldn’t you stop slashing carelessly with Occam’s razor?"

Here's a 2009 Reuters report about the Garlaschelli replica.

Update for 3:50 p.m. ET Dec. 26: Di Lazzaro sent this response to Nickell's questions via email:

"In 1978, several sticky tapes were used to sample the Shroud in different points of the body image. When the image fibers were pulled out of the adhesive, their colored coatings had been stripped off the fiber and remained in the adhesive. These coatings were independently analyzed by Profs. Alan Adler and Ray Rogers, and all of them were too thin to measure accurately with a standard optical microscope. This means the thickness of all coatings was smaller than the visible light wavelength, say thinner than 0.6 micrometer.

"Recently, these results have been confirmed by a direct measurement of another fiber, showing the thickness of the colored coating around the fiber is about 0.2 micrometer. As a consequence, there is quite a good probability most of the image fibers throughout the body image have a coloration depth smaller than 0.6 micrometers.

"Prof. Garlaschelli claimed he obtained 'a superficial coloration' without mentioning 'how much' superficial. Is it 100 micrometers thick? 10 micrometers? One micrometer? Nobody knows. I asked chemists [who are] colleagues at ENEA, and they told me it is impossible to obtain a coloration depth smaller than 10 to 20 micrometers with the chemicals used by Prof. Garlaschelli. This fact alone means the results of Garlaschelli are not comparable with the Shroud image.  Mr. Nickell may be interested to know Prof. Garlaschelli refused to reply the letter sent to the editor of JIST (the journal that published his results) where several points of his work were criticized, including the lack of a measurement of the coloration depth.

"Coming to the question of Mr. Nickell: We never claimed to have reproduced the whole Shroud image. We were interested to gain a deeper insight into the physical and chemical processes that generated such an unusual image. And we were successful to find photochemistry processes that are able to generate a Shroud-like coloration of linen fibers.

"Concerning Occam's razor, I am a scientist, and when I wish to understand a phenomenon, seeking for a scientific explanation, I use microscopes, spectrometers, image detectors and other laboratory tools. I see Mr. Nickell prefers using philosophical instruments like the medieval Occam's razor, a theory proposed in the 14th century. Each of us is free to choose the most familiar tool to find answers."

Update for noon ET Dec. 27: And Nickell responds...

"Di Lazzaro equates the depth of colored coatings that were stripped from surface fibers (using adhesive tape) with the depth of penetration that might be determined by cross-sectioning of actual threads, then asserts that a single fiber’s examination (still apparently not cross-sectioned) has 'confirmed' the dubious claims. Given the tremendous evidence against the 'shroud' — its incompatibility with Jewish burial practices, lack of historical record, bishop's report of the forger’s confession, the still-bright-red 'blood' which failed forensic serological tests, the presence of pigments and paints throughout the image, three laboratories' radiocarbon dating of the cloth to the time of the confession (1260–1390), and much additional evidence — it would seem that Di Lazzaro is straining at a gnat and attempting to swallow a camel. Let him produce a shroudlike image according to whatever theory he can muster, and we'll talk again."

HAIMEN, Guangdong Province—It wouldn’t have been fair or accurate to call it a China Spring, but for a moment it was worth wondering: Was this the beginning of a Guangdong Spring?

Since September, residents in a fishing village called Wukan, in the southern coastal province of Guangdong, had been protesting against their local government over, specifically, illegal land grabs and, more generally, corruption.  This was a town where one man had held sway as the Communist Party chief for four decades.

---

The situation grew explosive two weekends ago when one of the protest organizers died in police custody, triggering a widespread and cohesive revolt that saw thousands of people run the local officials and police out of town—the first time the Communist Party appeared to have lost total control of a town.

The authorities responded by laying siege on Wukan, preventing food and other supplies from reaching the 20,000-strong population, and censoring all mention of the latest developments in Chinese media or on the Internet.  In turn, the residents welcomed foreign and Hong Kong journalists to cover their plight.

Negotiations between the two sides kicked into high gear even as the situation escalated. The villagers threatened to march to the government offices of a nearby town unless their demands were met, potentially pitting them against thousands of riot and paramilitary police deployed along the main road leading in and out of Wukan.

In the end, cooler tempers prevailed amidst government compromises, but just as the Wukan standoff appeared to ease, reports of more protests nearby surfaced on Tuesday on the Internet.

Suddenly, the province in which its Communist Party head had promoted a “Happy Guangdong” campaign no longer seemed so happy.  At least not in this southeastern coastal corner.

At least three other pockets of unrest had flared up in districts of a large city near Wukan:  two of the groups were protesting similar examples of illegal land seizures and a third, the largest outbreak of demonstrations, was over government plans to build a coal-fired power plant in Haimen.

Though difficult to confirm, the initial reports described thousands of residents converging on the main local government office and organizing a sit-in on a key highway entrance to protest the development plans.  Local residents were quoted as saying they hoped foreign journalists would cover their story.

Before long, photographs emerged on Sina Weibo and other Chinese microblogs showing large numbers of paramilitary police in riot gear lining up against civilians in Haimen, a large town about 70 miles away from Wukan.  Tear gas was fired and clashes ensued.  Rumors also circulated that at least two boys had been killed in the confrontations; the government denied them.

Protests are not unusual in China.  In fact, according to the most recent official statistics, 2009 saw more than 90,000 “mass incidents,” as the Chinese government calls protests, across the country.  Land grabs and pollution concerns are among the top grievances.

Although the protests in Wukan and Haimen appear unrelated, it seemed a remarkable coincidence that two demonstrations adopting similar tactics would spring up within several dozen miles of one another. 

Heavy-handed police tactics
On Thursday, the streets of Haimen looked like those of any other comparable-sized Chinese town: food stalls, shops, sleepy government buildings, a high school, and a population that relies mostly on motorbikes to get around.

Mid-morning, dozens of those motorbikes were massed near the Haimen highway entrance.  In the distance, scores of black-and blue-uniformed police wearing helmets were standing behind barricades that had been pulled across the toll gate to the highway.

A large gas station on the corner looked open, but was in fact not.  The station's attendants in bright yellow jackets were lazing around, directing traffic to the next station.  The only energy came from a discussion about the power plant taking place among some of motorbike riders.

A short excursion on the highway itself revealed a sizeable police presence.  Police vans lined up against the side, interspersed with ambulances, fire engines, and water cannon trucks.  Dozens of police in riot gear sat on the ground.  Near several other highway entrance ramps, police vehicles could be spotted behind the gates of nearby compounds.

A little over an hour later, the crowd around the main entrance ramp had grown.  Motorbikes whizzed back and forth a couple of hundred feet away from the police barricade.  Many of the riders were young.

Suddenly, a pop rang into the air and a group of young teenagers were scrambling back away from the highway barriers—a plume of smoke rose above them.  The teens had tried to sidle up along the side.  A murmur of “tear gas” arose in the crowd as people began rushing away, covering their faces.  Nostrils burned.

“They don’t have the right to treat people like this,” said a 24-year old local resident who only offered his surname, Li.  “Using tear gas?  It’s wrong.”

Rumors of cancer
A few miles away, a large power plant with two smokestacks sat under the hazy sun.  It was not in operation; local reports said the government had suspended it as well as the plans to build the second plant until further notice. 

Haimen residents called Hongdong — the hamlet of one-storey homes nearest the power plant —“Cancer Village.”  But inside Hongdong, a man working in a local medical clinic denied that cancer patients were on the rise.

Back in front of the highway entrance, a young man named Chen and his two friends on motorbikes watched the police.  They had joined in the protests on Wednesday, because they, too, were angry about the health hazards posed by the power plant.

“The ocean is polluted [because of the run-off from the plant],” said Chen, also 24 years old.  “You can’t fish in it any more.”

He and others in the crowd said the number of cancer cases in Haimen had grown since the power plant was constructed in 2009 and quoted local papers as saying 80 percent of the cancer patients at a major regional hospital came from their township.

Chen said news of the protest had spread by QQ, a popular instant messaging service, until it was blocked on Tuesday evening.  Then they relied on word of mouth.

On the following day, the protesters were demonstrating peacefully, without weapons, said Chen, but the police rushed out from behind the blockade into the crowd and began beating up people—including women. 

Many of the participants on Wednesday, according to residents, were young Chinese.  Several were injured, and countless others arrested—just as was the case on Tuesday.

They had picked the highway entrance, said Chen, because it would attract the greatest attention.  Unlike the existing power plant itself or the land where the second plant has been designated—both of which are removed from the main roads.

Hearing about Wukan
“Were you in Wukan?” was a question that crept up a few times in conversation with Haimen’s residents.  In the past couple of days, Chinese media had begun publishing reports on the dispute next door.  Moreover, many had heard through friends or acquaintances or on the Internet about the months-long confrontation in Wukan.

But no one said Wukan had inspired them to take action. 

“This [environment issue] has been a problem for us for a while,” said Li.

There appears to be another difference between Wukan and Haimen.  Local officials from Haimen have promised to come up with some sort of resolution in five days, according to Chen.  But later on Thursday evening, he said that many more young Chinese had been rounded up and detained.

A girl who was believed to have been swept away by a massive tsunami that devastated coastlines in Asia has reportedly shown up alive, nearly seven years to the day after she vanished.

Indonesian state news agency Antara reported the girl, named only as Wati, was aged eight when she was ripped from her mother's arms by the rushing waters near her home in West Aceh, Indonesia, in December 2004. Her mother, Yusniar, was trying to get her and two other children to safety at the time.

Antara reported Wednesday that the girl's grandfather, Ibrahim, met a teenager who had traveled from another region, Banda Aceh, saying she was trying to find her way home.

The girl said she could not remember any of her relatives' names apart from one -- Ibrahim, Antara said.

He became convinced the girl was Wati, and her parents also later identified the girl as their daughter by a small mole and a scar over her eyebrow, Antara said.

It added that reporters were not immediately told what had happened to the girl during the time she was away.

Robotic helicopters capable of ferrying 3.5 tons of cargo in a single load are at work supplying NATO troops in Afghanistan, according to a defense technology blog.

The helicopter is a Lockheed Martin / Kaman Aerospace K-Max designed for battlefield cargo resupply. Confirmation of its use in Afghanistan means "we're now in the age of unmanned logistics," Paul Mcleary writes for Aviation Week's Ares blog.

The technology will put fewer soldiers at risk flying over enemy lines on re-supply missions. That doesn't mean, however, that the military will put the helicopters directly in harm's way. 

"Most of the missions will be conducted at night and at higher altitudes," Marine Capt. Caleb Joiner, mission commander, said in a news release. "This will allow us to keep out of small arms range."

While the helicopter should save lives on the battlefield, how might robotic choppers and other supply vehicles translate to civilian life? Feel free to share your wishes in the comments section below.
