'Barrier of Bodies' Trapped Nightclub Fire Victims

The bodies of the young college students were found piled up just inside the entrance of the Kiss nightclub, among more than 230 people who died in a cloud of toxic smoke after a blaze enveloped the crowded locale within seconds and set off a panic.

Hours later, the horrific chaos had transformed into a scene of tragic order, with row upon row of polished caskets of the dead lined up in the community gymnasium in the university city of Santa Maria. Many of the victims were under 20 years old, including some minors.

As the city in southern Brazil prepared to bury the 233 people killed in the conflagration caused by a band's pyrotechnic display, an early investigation into the tragedy revealed that security guards briefly prevented partygoers from leaving through the sole exit. And the bodies later heaped inside that doorway slowed firefighters trying to get in.

"It was terrible inside — it was like one of those films of the Holocaust, bodies piled atop one another," said police inspector Sandro Meinerz. "We had to use trucks to remove them. It took about six hours to take the bodies away."

Survivors and another police inspector, Marcelo Arigony, said security guards briefly tried to block people from exiting the club. Brazilian bars routinely make patrons pay their entire tab at the end of the night before they are allowed to leave.

"It was chaotic and it doesn't seem to have been done in bad faith because several security guards also died," he told The Associated Press.

Later, firefighters responding to the blaze initially had trouble entering the club because "there was a barrier of bodies blocking the entrance," Guido Pedroso Melo, commander of the city's fire department, told the O Globo newspaper.

Police inspectors said they think the source of the blaze was a band's small pyrotechnics show. The fire broke out sometime before 3 a.m. Sunday and the fast-moving fire and toxic smoke created by burning foam sound insulation material on the ceiling engulfed the club within seconds.

Authorities said band members who were on the stage when the fire broke out later talked with police and confirmed they used pyrotechnics during their show.

Meinerz, who coordinated the investigation at the nightclub, said one band member died after escaping because he returned inside the burning building to save his accordion. The other band members escaped alive because they were the first to notice the fire.

The fire spread so fast inside the packed club that firefighters and ambulances could do little to stop it, survivor Luana Santos Silva told the Globo TV network.

"There was so much smoke and fire, it was complete panic, and it took a long time for people to get out, there were so many dead," she said.

Most victims died from smoke inhalation rather than burns. Many of the dead, about equally split between young men and women, were also found in the club's two bathrooms, where they fled apparently because the blinding smoke caused them to believe the doors were exits.

There were questions about the club's operating license. Police said it was in the process of being renewed, but it was not clear if it was illegal for the business to be open. A single entrance area about the size of five door spaces was used both as an entrance and an exit.

Get cirrus in the fight against climate change

FEATHERY cirrus clouds are beautiful, but when it comes to climate change, they are the enemy. Found at high-altitude and made of small ice crystals, they trap heat - so more cirrus means a warmer world. Now it seems that, by destroying cirrus, we could reverse all the warming Earth has experienced so far.

In 2009, David Mitchell of the Desert Research Institute in Reno, Nevada, proposed a radical way to stop climate change: get rid of some cirrus. Now Trude Storelvmo of Yale University and colleagues have used a climate model to test the idea.

Storelvmo added powdered bismuth triiodide into the model's troposphere, the layer of the atmosphere in which these clouds form. Ice crystals grew around these particles and expanded, eventually falling out of the sky, reducing cirrus coverage. Without the particles, the ice crystals remained small and stayed up high for longer.

The technique, done on a global scale, created a powerful cooling effect, enough to counteract the 0.8 °C of warming caused by all the greenhouse gases released by humans (Geophysical Research Letters, DOI: 10.1002/grl.50122).

But too much bismuth triiodide made the ice crystals shrink, so cirrus clouds lasted longer. "If you get the concentrations wrong, you could get the opposite of what you want," says Storelvmo. And, like other schemes for geoengineering, side effects are likely - changes in the jet stream, say.

Different model assumptions give different "safe" amounts of bismuth triiodide, says Tim Lenton of the University of Exeter, UK. "Do we really know the system well enough to be confident of being in the safe zone?" he asks. "You wouldn't want to touch this until you knew."

Mitchell says seeding would take 140 tonnes of bismuth triiodide every year, which by itself would cost $19 million.

Anger mounts over corruption in recession-hit Spain

MADRID: Anger over a long list of corruption scandals implicating bankers, politicians and even members of the royal family is on the rise in recession-hit Spain, putting the spotlight on the failure of the country's democracy to tackle the issue.

At demonstrations against government austerity measures, chants against alleged shady deals by Spain's elite are as common as those venting anger at tax hikes and spending cuts to social services and public workers' pay.

Around 200-300 elected officials out of more than 50,000 in the country are currently implicated in corruption cases in regions governed both by both the left and the right, said the head of the Spanish branch of anti-corruption watchdog Transparency International, Jesus Lizcano.

"While small, it is a significant percentage and is a bit alarming and calls for an urgent response on the part of political parties," he said.

With taxpayers reeling under austerity measures and a record unemployment rate of 26 percent, many feel that "the political class is not able to resolve the economic crisis, that it is useless, and that they protect each other", said University of Santiago de Compostela political science professor Anton Losada.

The latest corruption scandal to make headlines involves Prime Minister Mariano Rajoy's centre-right Popular Party, whose popularity has plunged since it won a November 2011 election in a landslide.

Daily newspaper El Mundo reported on January 18 that former Popular Party treasurer Luis Barcenas distributed envelopes containing thousands of euros to party officials on top of their declared salaries.

It said the money came from commissions collected from construction firms, insurance companies and anonymous donors.

Top Popular Party officials have strongly denied any involvement in the affair and have kept their distance from Barcenas, who reportedly had up to 22 million euros ($29 million) in Swiss bank accounts until 2009.

Hundreds of people protested, chanting "thieves" and "shame", near the headquarters of the Popular Party in central Madrid on the day El Mundo published its allegations against Barcenas.

Corruption scandals have even hurt the popularity of King Juan Carlos after one implicated a member of his family.

His son-in-law Inaki Urdangarin was accused last year of embezzling public money paid by regional governments to a charitable organisation based in Mallorca which he chaired from 2004 to 2006.

"During the past three weeks people have been very, very, very angry, there has been a growing social alarm and it is very important that politicians take this issue seriously," said Lizcano.

The corruption scandals have shaken Spaniards' faith in politicians nearly four decades after the death of dictator General Francisco Franco in 1975 paved the way for the country's return to democracy.

Three in four Spaniards think political corruption is rising in the country and that politicians get better treatment in the courts than regular citizens, according to a poll published in conservative newspaper ABC on January 20.

Rajoy has ordered an internal investigation into the finances of the party and has vowed to take action if any wrongdoing is uncovered.

Last year, his government vowed to table a law on political transparency and earlier this month it proposed an anti-corruption pact with other parties.

After Franco's death the country's 17 autonomous communities were given broad powers with little oversight over their finances, which are largely blamed for the country's bloated public deficit.

"There is an urgent need for parties to publish their accounts and their sources of financing," as in other European nations, said Lizcano.

He said there is too much involvement by politicians in institutions such as the courts and regional savings banks.

Popular anger was fuelled this month when Spanish telecom giant Telefonica hired Rodrigo Rato, a former head of the International Monetary Fund, as an advisor just weeks after he appeared in court in a fraud case involving bailout-out bank Bankia, which he once headed.

Lizcano has little faith that the government will follow through on its vow to step up the fight against corruption.

"I am sceptical but I hope I am wrong," he said.

The ultimate gall of a heartless iPhone thief

An object of desire?

(Credit:
CNET)

One should never expect justice in life.

The best one can hope for is poetry.

And yet, just once or twice, both manage to collide with a deliciousness that moves the soul.

Here is the tale of a teenage girl who had her iPhone stolen.

As The New York Times composes it, the girl had her
iPhone 4S ripped from her by a teenage boy in Brooklyn's notoriously difficult Prospect Park.

iPhone theft is rather popular in New York. Indeed, Mayor Bloomberg recently suggested that it's responsible for an increase in crime in the city.

Anyway, the iPhone-less girl collared a couple of policemen, but the miscreant was not to be found.

However, the thief then decided that he'd try to get some money for the phone. So he met a man on a Flatbush street -- as you do.

The man asked to take a look at the phone. Perhaps he wanted to see whether Siri was still inside.

Then, he ran off with it.

Yes, this is slightly poetic. But we've only just begun.

You see, the boy thief was not very happy. After all, he'd had his recently acquired property stolen. So he went off in search of a policeman to report the crime.

I pause for your sound effects.

Thank you.

More Technically Incorrect

The police reacted with unusual efficiency. They corralled both the boy and the man who had taken Siri from him. But they still assumed the boy was the victim.

Are you ready for verse three?

The phone rang. It was the girl trying to do a deal to get her phone back. The police realized something might be amiss here. This seemed to be a miss who actually owned the phone.

So they waited for her to arrive in Flatbush. She recognized the boy's sneakers. They were pink.

I pause for your further sound effects.

The police decided it was time to play Solomon. They would slice the phone in two if one party didn't renounce their claim to the phone.

No, wait. They asked both the girl and the pink-sneakered boy to unlock the phone with the PIN code.

You're already there, aren't you? Both the actual thieves were brought to justice -- the actual kind. And the girl got her phone back.

There are several morals to this story.

One, don't steal iPhones if you're wearing pink sneakers.

Two, if someone does unto you as you have done unto someone else, take it onto the chin. It will help you understand the feelings of others.

Three, if you're the kind of New Yorker who thinks they can always get away with it, well, you can't. Not always.

Pictures: The Story Behind Sun Dogs, Penitent Ice, and More

Photograph by Art Wolfe, Getty Images

If you want the beauty of winter without having to brave the bone-chilling temperatures blasting much of the United States this week, snuggle into a soft blanket, grab a warm beverage, and curl up with some of these natural frozen wonders.

Nieve penitente, or penitent snow, are collections of spires that resemble robed monks—or penitents. They are flattened columns of snow wider at the base than at the tip and can range in height from 3 to 20 feet (1 to 6 meters). The picture above shows the phenomenon in central Chile. (See pictures of the patterns in snow and ice.)

Nieve penitente tend to form in shallow valleys where the snow is deep and the sun doesn't shine at too steep an angle, said Kenneth Libbrecht, a physicist at the California Institute of Technology in Pasadena who studies ice crystal formation.

As the snow melts, dirt gets mixed in with the runoff and collects in little pools here and there, he said. Since the dirt is darker in color than the surrounding snow, the dirty areas melt faster "and you end up digging these pits," explained Libbrecht.

"They tend to form at high altitude," he said. But other than that, no one really knows the exact conditions that are needed to form penitent snow.

"They're fairly strong," Libbrecht said. "People have found [the spires] difficult to hike through."

Squatter, Bank of America Battle for $2.5M Mansion

Bank of America is taking a Florida man to court after he attempted to use an antiquated state law to legally take possession of a $2.5 million mansion that is currently owned by the bank.

Andre "Loki" Barbosa has lived in a five-bedroom Boca Raton, Fla., waterside property since July, and police have reportedly been unable to remove him.

The Brazilian national, 23, who reportedly refers to himself as "Loki Boy," cites Florida's "adverse possession" law, in which a party may acquire title from another by openly occupying their land and paying real property tax for at least seven years.

The house is listed as being owned by Bank of America as of July 2012, and that an adverse possession was filed in July. After Bank of America foreclosed on the property last year, the Palm Beach County Property Appraiser's Office was notified that Barbosa would be moving in, according to the South Florida Sun-Sentinel.

The Sun-Sentinel reported that he posted a notice in the front window of the house naming him as a "living beneficiary to the Divine Estate being superior of commerce and usury."
On Facebook, a man named Andre Barbosa calls the property "Templo de Kamisamar."

After Barbosa gained national attention for his brazen attempt, Bank of America filed an injunction on Jan. 23 to evict Barbosa and eight unidentified occupants.

In the civil complaint, Bank of America said Barbosa and other tenants "unlawfully entered the property" and "refused to permit the Plaintiff agents entry, use, and possession of its property." In addition to eviction, Bank of America is asking for $15,000 in damages to be paid to cover attorney's expenses.

Police were called Dec. 26 to the home but did not remove Barbosa, according to the Sentinel. Barbosa reportedly presented authorities with the adverse possession paperwork at the time.

Mark Potok, a senior fellow at the Southern Povery Law Center, says police officers may be disinclined to take action even if they are presented with paperwork that is invalid.

"A police officer walks up to someone who is claiming a house now belongs to him, without any basis at all, is handed a big sheaf of documents, which are incomprehensible," Potok said. "I think very often the officers ultimately feel that they're forced to go back to headquarters and try to figure out what's going on before they can actually toss someone in the slammer."

A neighbor of the Boca property, who asked not be named, told ABCNews.com that he entered the empty home just before Christmas to find four people inside, one of whom said the group is establishing an embassy for their mission, and that families would be moving in and out of the property. Barbosa was also among them.

The neighbor said he believes that Barbosa is a "patsy."

"This young guy is caught up in this thing," the neighbor said. "I think it's going on on a bigger scale."

Barbosa could not be reached for comment.

The neighbor said that although the lights have been turned on at the house, the water has not, adding that this makes it clear it is not a permanent residence. The neighbor also said the form posted in the window is "total gibberish," which indicated that the house is an embassy, and that those who enter must present two forms of identification, and respect the rights of its indigenous people.

"I think it's a group of people that see an opportunity to get some money from the bank," the neighbor said. "If they're going to hold the house ransom, then the bank is going to have to go through an eviction process.

"They're taking advantage of banks, where the right hand doesn't know where the left hand is," the neighbor said. "They can't clap."

Latin America, Europe open summit to boost trade

SANTIAGO: Latin American and European leaders open a two-day summit Saturday to give a fresh impetus to efforts to seal a free trade agreement between their two blocs.

Attending the gathering are some 45 leaders, including German Chancellor Angela Merkel, Spanish Prime Minister Mariano Rajoy, Brazilian President Dilma Rousseff, Cuban leader Raul Castro as well as European Council President Herman Van Rompuy and European Commission President Jose Manuel Barroso.

Although the two blocs have met seven times, it is the 27-member European Union's first summit with the Community of Latin American and Caribbean States (CELAC, its Spanish-language acronym).

Set up in Caracas in December 2011 at the behest of Venezuelan President Hugo Chavez, CELAC groups all American nations except the United States and Canada and aims to boost regional trade and institutional cooperation,.

Chavez, who is convalescing from cancer surgery in Cuba, will not attend the weekend gathering.

Monday, CELAC leaders will hold their own summit here, with Cuba taking over the chairmanship from Chile for one year.

The meeting will seal Cuba's full regional reintegration and mark a major diplomatic coup for President Castro, whose communist-ruled country is still reeling from a 50-year-old crippling US trade embargo.

The 33 CELAC leaders hope to overcome their ideological and economic differences to foster greater regional integration.

"Our efforts (in this area) have not lived up to that is needed and what Latin America deserves," Chilean President Sebastian Pinera conceded.

Shortly before Castro landed here on Friday, about 200 people protested both for and against Havana.

An estimated 100 demonstrators massed outside the Cuban embassy, heeding a call by Chile's ruling party, the conservative Independent Democratic Union, or UDI, to demonstrate against the Castro`s presence in the Chilean capital.

The UDI accuses Castro of harboring the murderers of their party's founder, Jaime Guzman, a senator who was killed in 1991 by the nearly extinct radical leftist group Patriotic Front of Manuel Rodriguez.

The UDI president, along with other lawmakers, also came to the embassy to deliver a letter demanding to know the whereabouts in Cuba of those they allege killed Guzman: Ricardo Poblete, and three other accomplices.

However, the lawmakers were denied entry and then threw the letter into the garden.

Another 100 demonstrators, from a "Group of Solidarity with Cuba," also gathered near the embassy to show support for Cuba .

Ahead of the EU-CELAC summit, Pinera, the host, said the meeting aimed to "to seal a new strategic alliance for development and more open markets."

"It will be the first timethat Latin America will speak with one voice" with Europe, Chilean Foreign Minister Alfredo Moreno said recently.

The EU is the biggest outside investor in Latin America, with three per cent of the direct foreign investment in CELAC or $385 billion in 2010.

Thursday, Van Rompuy and Barroso attended a EU-Brazil summit with Brazilian President Dilma Rousseff in Brasilia.

The two sides called for the speedy conclusion of a free trade pact between the EU and the South American trading bloc Mercosur.

Negotiations over the pact have so far stumbled over differences on agriculture -- notably Europe's subsidies to its farmers, which undermine South America's efforts to sell its own products.

Meanwhile, a parallel Summit of the Peoples got under way here Friday with a march of 1,000 leftists protesting capitalist economic policies.

The march turned violent when hooded demonstrators tore down traffic lights and shops' shutters in central Santiago, prompting police to intervene with water cannons ans tear gas.

At least five protesters were arrested.

The two-day counter-summit brings together representatives of more than 400 social movements from across Latin America and Europe.

Review: While "jOBS" fawns over subject, film falls flat

Ashton Kutcher as Steve Jobs in "jOBS."

(Credit:
Five Star Feature Films)

PARK CITY, UTAH--The eagerly awaited biopic "jOBS" opens in 2001, when Apple's iconic co-founder arrives at Town Hall on Apple's Cupertino campus with good news. A secret team, Steve Jobs tells his employees, has built a product that will revolutionize the way everyone listens to music. Before he can even show them the iPod, the employees have sprung to their feet, wild-eyed and ecstatic, and their thunderous applause is eventually drowned out only by strings swelling in the background. It's a scene that sets the tone for all that is to follow: for most of the film's two hours, "jOBS" rarely stops clapping for its subject.

The team behind "jOBS," which was directed by Joshua Michael Stern, began working on the project shortly before Jobs retired from Apple in 2011. The script by first-time screenwriter Matt Whiteley covers Jobs' life from 1974, when Jobs attended classes at Reed College in Oregon, to 2001, when he announced the
iPod to Apple employees. Along the way "jOBS" covers most of the major milestones of its subject's time at Apple: the Apple I, the Apple II, the Lisa, and the Macintosh all are shown in development, as Jobs (a hard-working Ashton Kutcher) works to bring his vision of personal computing to the masses. Jobs hand-picks John Sculley to become Apple's CEO, hoping his marketing expertise will help the company overtake IBM in the PC market. But Sculley disappoints Jobs, who alienates his allies on Apple's board of directors and is ousted from the company he started. Only Apple's near-death experience in 1997 is enough to bring him back to Apple -- first as an adviser, then as an "interim" CEO -- and with the success of the Bondi blue iMacs, Apple was ascendant once again.

It's a story that will be familiar to readers of Walter Isaacson's recent Jobs biography or any number of other histories of the company. The opportunity "jOBS" had was to render these legendary events of Silicon Valley's history on screen, and to dramatize the contradictions of a man who remained unknowable even to some of those closest to him.

The movie gives it a shot. Kutcher drew skepticism when he was announced as the film's lead, despite an uncanny resemblance to the man he would be playing. But he throws himself into the role, inhabiting Jobs in his mannerisms and gestures while doing a more than creditable impression of the man's voice. Kutcher also captures Jobs' deliberate, slightly hunched-over walk. At moments, as during an enjoyable sequence in which Jobs recruits members for the Macintosh team, Kutcher disappears into the role.

The filmmakers do show Jobs being a jerk: he sleeps around, he yells at people, he parks in handicapped spaces. He persuades Steve Wozniak (Josh Gad) to perform crucial work for him, but lies about how much he is being paid, so he can dramatically underpay his best friend. An hour into the movie, he fires someone during an argument over font availability on the Lisa.

Yet the filmmakers are more interested in showing Jobs going about the work of being a genius. Over and over again, minor characters explain to him why something can't be done; Kutcher-as-Jobs smiles enigmatically and waves away their concerns. (It is left to someone else, far off screen, to turn his visions into reality.) We watch Jobs out-negotiate a computer parts store owner, lecture the team making the Lisa, and ride to the rescue of the Macintosh. Each time, he speaks of how the technology Apple is building will improve the lives of average people. Co-workers argue with him, but they never get anywhere, because their parts are poorly written and the filmmakers have no interest in showing their subject being wrong about his work. The film mentions Lisa's failure but has no interest in what part Jobs played in that failure; all Apple failures in "jOBS" are portrayed as the result of conservative, backward-thinking executives beholden only to their shareholders. The result is that the viewer spends two hours watching cardboard cutouts lose arguments to Ashton Kutcher.

Kutcher speaks fully 40 percent of the lines in "jOBS." Unfortunately, he has almost no one to play off of. Dermot Mulroney, as early Apple investor Mike Markkula, shakes his head at Jobs' excesses without ever really challenging him. J.K. Simmons, as the Apple board chairman who oversees Jobs' ouster, is a cartoon villain. Women in the film barely exist; an actress playing Chris-Ann Brennan has a single under-written scene informing a young Jobs that she is carrying his baby; years later in the film, a small scene shows Jobs at home with his wife. Only Gad, as Wozniak, gets a scene standing up to the great man -- as Woz quits Apple, he criticizes Jobs for losing his humanity amid a single-minded pursuit of making great products. It's something even Jobs' staunchest admirers have to wrestle with, and the film could have used more of that.

Others will write of the things "jOBS" omits, gets wrong, or simply avoids. My primary disappointment was in how shallow the film felt, given the extensive historical record. In the early days Jobs' co-workers had to wrestle with a man who smelled bad, who cried often, who yelled constantly, who missed deadlines, who overspent his budget by millions. He did it in service of products we love and use daily, and yet his obsessions took a toll on those around him. It also inspired others to do the best work of their lives, pushing themselves further than they ever imagined they can go. There is great drama to be found in all that, but it is not to be found in the saccharine "jOBS."
