Brazil Nightclub Fire: 232 Dead, Hundreds Injured













Flames raced through a crowded nightclub in southern Brazil early Sunday, killing more than 230 people as panicked partygoers gasped for breath in the smoke-filled air while stampeding toward a single exit partially blocked by those already dead. It appeared to be the world's deadliest nightclub fire in more than a decade.



Witnesses said a flare or firework lit by band members may have started the blaze.



Television images showed smoke pouring out of the Kiss nightclub as shirtless young men who had attended a university party joined firefighters using axes and sledgehammers to pound at windows and walls to free those trapped inside.



Guido Pedroso Melo, commander of the city's fire department, told the O Globo newspaper that firefighters had a hard time getting inside the club because "there was a barrier of bodies blocking the entrance."



Teenagers sprinted from the scene desperately seeking help. Others carried injured and burned friends away in their arms.



"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," survivor Luana Santos Silva told the Globo TV network.



The fire spread so fast inside the packed club that firefighters and ambulances could do little to stop it, Silva said.

Another survivor, Michele Pereira, told the Folha de S. Paulo newspaper that she was near the stage when members of the band lit flares that started the conflagration.



"The band that was onstage began to use flares and, suddenly, they stopped the show and pointed them upward," she said. "At that point, the ceiling caught fire. It was really weak, but in a matter of seconds it spread."



Police Maj. Cleberson Braida Bastianello said by telephone that officials counted 232 bodies that had been brought for identification to a gymnasium in Santa Maria, a major university city with about 250,000 residents at the southern tip of Brazil, near the borders with Argentina and Uruguay.



An earlier count put the number of dead at 245. Another 117 people were being treated at hospitals, he said.



Brazil President Dilma Roussef arrived to visit the injured after cutting short her trip to a Latin American-European summit in Chile.



"It is a tragedy for all of us," Roussef said.



Most of the dead apparently suffocated, according to Dr. Paulo Afonso Beltrame, a professor at the medical school of the Federal University of Santa Maria who went to the city's Caridade Hospital to help victims.



Beltrame said he was told the club had been filled far beyond its capacity during a party for students at the university's agronomy department.



Survivors, police and firefighters gave the same account of a band member setting the ceiling's soundproofing ablaze, he said.



"Large amounts of toxic smoke quickly filled the room, and I would say that at least 90 percent of the victims died of asphyxiation," Beltrame told The Associated Press by telephone.



"The toxic smoke made people lose their sense of direction so they were unable to find their way to the exit. At least 50 bodies were found inside a bathroom. Apparently they confused the bathroom door with the exit door."



In the hospital, the doctor "saw desperate friends and relatives walking and running down the corridors looking for information," he said, calling it "one of the saddest scenes I have ever witnessed."

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.

Oppo BDP-105: Not your average Blu-ray player



The Oppo BDP-105 Blu-ray, SACD, and DVD-Audio player



(Credit:
Oppo)


Even by Oppo's high standards the BDP-105 is an extraordinary Blu-ray player. Sure, it's loaded with up-to-the-second features -- 4K upscaling, 2D-to-3D conversion, and a high-quality USB 2.0 digital-to-analog converter -- but what really makes the Oppo special is the sound. Pop the cover and look inside and you'll see why. Most of the 17-pound component's chassis space is devoted to the audio circuitry. That's nice, but the audio advantages will be completely irrelevant if you connect the BDP-105 to your receiver with a HDMI cable (the digital-to-analog conversion would then be handled in the receiver). The 105 was designed for buyers still using older $1,000 or $2,000 receivers from the days before HDMI connectivity, that would like to hear the Blu-rays' high-resolution DTS Master Audio or Dolby TrueHD soundtracks at their best. Since the audio won't be transmitted over the HDMI cable, you would run audio cables between the 105's seven- or five-channel analog outputs and the AV receiver's analog inputs.

Or you could forgo the receiver entirely and hook up the BDP-105 directly to a five- or seven-channel power amplifier. That approach would produce better sound quality, but would lack the connectivity, flexibility, and convenience of today's better receivers. Still, the BDP-105/power amp combo would sound better and be more powerful than most top-of-the-line receivers. The 105's connectivity options won't match any decent receiver, but its connectivity suite is a lot more extensive than most Blu-ray players. The Oppo has two HDMI inputs, so you can connect external devices such as set-top boxes and network streaming devices, three USB 2.0 ports, coaxial and optical digital inputs for satellite boxes, televisions, video-game consoles, etc., and there's a built-in headphone amplifier. The BDP-105's extensive bass management options are on par with a lot of AV receivers. The player's digital volume control is easy to use.


For my listening tests, I hooked up the BDP-105 ($1,199) with an assortment of self-powered Audioengine and Emotiva monitor speakers, and a Hsu subwoofer. With this setup I didn't need to use an AV receiver or separate power amp, but the Raconteurs' "Live at Montreux" Blu-ray was vivid and very live sounding. The system's freewheeling dynamics were really impressive, and the surround mix on King Crimson's "Red" DVD-A projected a remarkably seamless wrap-around soundstage. Each instrument was precisely focused in a near 360-degree sound environment.



The BDP-105 has full speaker setup and bass management options, just like an AV receiver.

Classical music on SACD was just as impressive, the front three speakers produced a three-dimensional soundstage with lots of depth, and string tone was top notch. Dramatic movies on Blu-ray and DVD sounded great. I plugged headphones into the BDP-105, but the sound wasn't special, Schiit Audio's $99 Magni headphone amp was a lot better.


The $499 Oppo BDP-103 shares most of the BDP-105's features, but lacks the upgraded digital-to-analog converters, so if you're planning on using HDMI to connect the player to your receiver, buy the 103, and save $700. You can use the 103's 7.1 analog outputs with an old high-end receiver lacking HDMI connectivity, but the 103's digital converters are a step down from the ones in the 105.


The BDP-105 is an update of the Oppo BDP-95, and the new one has lots of features the old player lacks, but the two players sound about the same. Oppo still has 95s in stock and sells them for $799.


Oppo sells direct and offers a 30-day money-back guarantee, and the return shipping is free.

Anonymous Hijacks Federal Website Over Reddit Co-Founder's Suicide


Jan 26, 2013 12:27pm







ap commission website hacked 130126 wblog Anonymous Hijacks Federal Website, Threatens DOJ Document Dump

(AP Photo)


Activists from the hacker collective known as Anonymous assumed control over the homepage of a federal judicial agency this morning.


In a manifesto left on the defaced page, the group demanded reform to the American justice system and what the activists said are threats to the free flow of information.


The lengthy essay largely mirrors previous demands from Anonymous, but this time the group also cited the recent suicide of Reddit co-founder and activist Aaron Swartz as has having “crossed a line” for their organization. Swartz was facing up to 35 years in prison on computer fraud charges.


Prosecutors said he had stolen thousands of digital scientific and academic journal articles from the Massachusetts Institute of Technology with the goal of disseminating them for free.

Anonymous says Swartz was “killed because he was forced into playing a game he could not win — a twisted and distorted perversion of justice — a game where the only winning move was not to play.”


“There must be a return to proportionality of punishment with respect to actual harm caused,” it reads, also mentioning recent arrests of Anonymous associates by the FBI.


In their statement, the hackers say they targeted the homepage of the Federal Sentencing Commission for “symbolic” reasons.


The group claimed that if their demands were not met they would release a trove of embarrassing internal Justice Department documents to media outlets. Anonymous named the files after Supreme Court justices and provided hyperlinks to them from the defaced page.


As of press time the commission’s site had been taken offline but an earlier attempt by CNN to follow the files’ links yielded dead-ends, mostly offline sites.


The file names use an “.aes256″ suffix, denoting a common encryption protocol. The same system was used to encrypt the Wikileaks Afghan war documents before their release.

Army kills six as Iraq demos call for PM to quit






FALLUJAH: Soldiers fired on an anti-government rally west of Baghdad on Friday, killing six demonstrators, the first deaths in weeks of increasingly angry protests calling for Iraq's premier to quit.

The shootings came as tens of thousands rallied in majority Sunni areas of the country, railing against alleged targeting of their minority community by the Shiite-led authorities, while in a cross-sectarian show of support, Shiite clerics called on the government to heed their demands.

Protesters had been moving to an area in east Fallujah, a predominantly Sunni town about 60 kilometres from Baghdad, but were blocked off by soldiers deployed from Baghdad, police Captain Nasser Awad told AFP. They began throwing bottles of water at the troops, who opened fire.

Six demonstrators were killed, all of them from gunshot wounds, said Khaled Khalaf al-Rawi, a doctor at Fallujah hospital. Rawi said 35 others were wounded, the majority of them as a result of gunfire.

Defence ministry spokesman Major General Mohammed al-Askari said an inquiry had been opened, and pledged that victims would be financially compensated.

Officials in Fallujah earlier said the army had vacated the town and had been ordered to transfer security responsibility to the police.

Mosques in Fallujah used loudspeakers to urge calm, and security forces imposed a curfew across the town.

Prime Minister Nuri al-Maliki called for restraint on the part of security forces in a statement issued by his office, but also blamed protesters for "raising tensions" and insisted the soldiers had been "attacked".

"This is what Al-Qaeda and terrorist groups are seeking to exploit," he said, referring to apparent sectarian tensions.

Similar demonstrations, meanwhile, took place in the nearby city of Ramadi, like Fallujah a mostly Sunni town in the western province of Anbar, as well as the cities of Samarra, Mosul and Baquba, all north of Baghdad.

Rallies also took place in Sunni neighbourhoods of the capital.

The longest-running of the protests, in Ramadi, has cut off a key trade route linking Baghdad to Jordan and Syria for a month.

"The government should respond immediately to the demands of protesters, before we start a revolution and put an end to it (the government)," said Hassan al-Zaidi, a tribal chief who was protesting in Baquba.

Demonstrators in Samarra held banners calling for Prime Minister Nuri al-Maliki to quit, while protesters in Baquba called for the "fall of the regime", and held banners that read, "Iran out, Baghdad always free", referring to Sunni claims that the government is controlled by Shiite neighbour Iran.

Rallies also called for freeing prisoners who demonstrators allege are being wrongfully held, with one banner in Mosul reading, "Enough talk -- break the doors of the prisons".

Shiite clerics, meanwhile, called for the government to heed demonstrators' demands.

"There must be agreement with the demands," Sadr al-Din al-Qubanji, linked to the Supreme Iraqi Islamic Council political bloc, said in his Friday sermon in the holy Shiite city of Najaf, south of Baghdad. "Nobody can say that the government is clean from errors."

If the authorities did not work to address protesters' demands, Qubanji warned, "There is another way, which can collapse the entire political process in Iraq."

The protests have hardened opposition against Maliki and come amid a political crisis less than three months ahead of key provincial elections.

Demonstrators began by criticising the alleged exploitation of anti-terror laws to detain Sunnis wrongfully, but have since moved on to calling for the premier to quit.

The government has sought to curb the rallies by claiming to have released nearly 900 prisoners in recent weeks, with a senior minister publicly apologising for holding detainees without charge.

Public school system's e-mail sends parents to sex site



The botched link in the e-mail led to this page. Rather elegant.

Screenshot by Chris Matyszczyk/CNET)


School officials don't always do their homework.


Errors creep in -- sometimes creepy ones.


Still, who cannot feel a pang of guffaw-suppressing empathy for whomever wrote an e-mail on behalf of the Chicago Public Schools system?


As CBS Chicago sniggers it, parents were being notified by the Schools system of adjustments to the Illinois Standards Achievement Test.


Helpfully, the e-mail notification included a link to the Illinois State Board of Education Web site.



More Technically Incorrect


Perhaps, though, there was a copy-paste failure. Or perhaps the author decided to type out the whole link. Or perhaps... well, anyway.


Somehow, an extra letter was added to the link, which led to something less than a happy ending.


For this link directed parents to a site -- Isbel.com -- where a group "works together to explore and enrich the modern woman's sex life and sensuality."


I am fairly sure that the Chicago Public Schools system wasn't suggesting that certain mothers of the kids needed to expand their sexual horizons.


I am also fairly sure that this site featured an image of the Kama Sutra -- which is not on the school syllabus.


The Schools system apologized and sent out an amended e-mail.


I wonder how many new enthusiasts Isbel.com secured before the amended e-mail went out.

5 Amazing Animal Navigators


A house cat named Holly, which made news this week for trekking nearly 200 miles (320 kilometers) back to her hometown, isn't the only supernavigator in the animal kingdom.

"Any animal that comes back to the right place after a long travel, or comes back to the same place again and again following a major movement, is amazing," said Martin Wikelski, a migration expert at the Max Planck Institute. (Read about great animal migrations in National Geographic magazine.)

Many animals have a built-in magnetic system, "like a regular compass," said Wikelski, who is also a National Geographic emerging explorer. (National Geographic News is part of the National Geographic Society.)

However, much is still unknown about how animals navigate—for instance, no one can explain Holly's incredible journey, the New York Times reported.

But more and more research is pointing to the role of smell in navigation, Wikelski noted.

"It's one of the most important mechanisms to tell you where you are and lead you home."

Wikelski told us about five impressive navigators that he believes push the limits of what's possible.

1. Eels. These long, bony fish make epic, mysterious treks across entire oceans. The European eel, for example, is born in European rivers but travels all the way to the Sargasso Sea (map), a distance of thousands of miles, to spawn. The baby eels then return to European rivers and, once it's time for them to spawn, follow their parents' path to very same place in the Sargasso Sea. "Nobody really knows how they do it," Wikelski said.

2. Bar-Tailed Godwit. This shorebird can fly in one go from its Alaska breeding grounds across the entire globe to New Zealand. In 2007, a female bar-tailed godwit got a feather in its cap for the longest nonstop bird migration ever measured—7,145 miles (11,500 kilometers) from Alaska to New Zealand. The bird completed the journey in just nine days, according to biologists who tracked the flight using satellite tags.

3. Blackpoll Warbler. This North American forest dweller has figured out an express way of getting to its winter refuge in Venezuela, Wikelski said. The bird fattens itself up before snagging a ride on a trade wind, sailing from the northeastern U.S. to South America in a hundred hours—entirely over the open ocean. "That's completely crazy," he said. On the way back home, the bird takes the more scenic route, stopping on land to rest and refuel.

4. Mexican Free-Tailed Bat. These flying mammals are common in Texas, where they form colonies in the millions. Wikelski, who was involved in a tracking study of the bats, discovered that they can fly up to 40 miles (70 kilometers) from their home caves in search of moths or mosquitoes. "At some point they turn around and … basically know how to find [their way] back," Wikelski said. Evidence suggests the animals use both landmarks and the smell of their fellow cave bats to point them home. (See bat videos.)

5. Sahara Desert Ant. These insects travel relatively long distances—up to 0.3 mile (0.5 kilometer)—from their central nest sites to search for food. Even though the ants run chaotically in many directions, they remember exactly how far they've gone by counting their steps, as well as navigating via polarized light patterns from the sun, Wikelski said. Finding their way back home is critical for these desert denizens—if they stay outside too long, they'll get fried in the sun.

These are just a sampling of incredible animals on the move. What other animal navigators have you observed? Tell us your stories in comments and we'll showcase the best ones.

Mars Rover Celebrates Milestone on Red Planet













It was never supposed to last this long. When the Mars rover Opportunity settled on the Martian surface nine years ago today, mission managers at NASA said they would be pleased if it lasted for 90 days.


Instead, it's been 3,201 days, and still counting. The rover has driven 22.03 miles, mostly at a snail's pace, from one crater to another, stopping for months at a time in the frigid Martian winters. The six motorized wheels, rated to turn 2.5 million times, have lasted 70 million, and are all still working.


"Opportunity is still in very good health, especially considering what it's gone through," said John Callas, manager of NASA's Mars Exploration Rover project. The surface of Mars is a pretty tough place; there can be temperature fluctuations of a hundred degrees each day. That's pretty hard on the hardware."


Video: '7 Minutes of Terror: A Landing on Mars


When Opportunity and its twin rover, Spirit, reached Mars in January 2004, there was a fair bit of sniping that NASA, with all that 90-day talk, was playing down expectations. It escalated when Steve Squyres of Cornell University, the principal investigator for the missions, said things like, "We're on Sol 300 of a 90-Sol mission." (A Sol is a day on Mars, and lasts 24 hours, 39 minutes.) Callas and others have insisted that the prediction was based on engineering, not a nod to public relations.










"There was an expectation that airfall dust would accumulate on the rover, so that its solar panels would be able to gather less electricity," said Callas. "We saw that on Pathfinder," a small rover that landed on Mars in 1997." The cold climate was also expected to be hard on the rovers' batteries, and changes in temperature from night to day would probably pop a circuit or two.


Instead, the temperatures weren't quite as tough as engineers had expected, and the rovers proved tougher. They did become filthy as the red Martian dust settled on them, reducing the sunlight on the solar panels -- but every now and then a healthy gust came along, surprising everyone on Earth by cleaning the ships off.

Spirit, in hilly territory on the other side of the planet, finally got stuck in crusty soil in 2009, and its radio went silent the next year. But Opportunity, though it's had some close calls, is -- well, you remember those commercials about the Energizer bunny.


So what do you do with an aging rover on a faraway planet? You keep using it. In its first weeks, NASA said Opportunity found chemical proof that there had once been standing water on the surface of Mars -- good news if you're looking for signs that the planet could once have been friendly to life. Since then, it's been sent to other places, with rocks and soil that are probably older, and with clay that may have been left by ancient rivers.


About 20 NASA staff members still work full-time on Opportunity at the Jet Propulsion Laboratory in Pasadena, Calif. Another 60 split their time between Opportunity and other projects, such as the Curiosity rover that landed last August. About 100 scientists, doing research on Mars, pop in and out.


In a few months, Callas said, Opportunity will head to an area nicknamed Cape Tribulation. The clay there could be rich in the minerals suggestive of past life.


They haven't done much to mark the ninth anniversary or the 3,200th Martian day, just a get-together earlier this week during a previously scheduled science conference. After that, Callas said, it was back to work.


"It's like keeping your car going," he said, "without ever having a chance to change the oil."
