Space Pictures This Week: Martian Gas, Cloud Trails

The sun is more than meets the eye, and researchers should know. They've equipped telescopes on Earth and in space with instruments that view the sun in at least ten different wavelengths of light, some of which are represented in this collage compiled by NASA and released January 22. (See more pictures of the sun.)

By viewing the different wavelengths of light given off by the sun, researchers can monitor its surface and atmosphere, picking up on activity that can create space weather.

If directed towards Earth, that weather can disrupt satellite communications and electronics—and result in spectacular auroras. (Read an article on solar storms in National Geographic magazine.)

The surface of the sun contains material at about 10,000°F (5,700°C), which gives off yellow-green light. Atoms at 11 million°F (6.3 million°C) gives off ultraviolet light, which scientists use to observe solar flares in the sun's corona. There are even instruments that image wavelengths of light highlighting the sun's magnetic field lines.

Immigration Plan Includes Path to Citizenship












A bipartisan group of senators on Monday formally unveiled their proposal to drastically overhaul the nation's immigration system, with the hope of passing a bill out of the Senate by late spring or early summer.


"We believe this will be the year Congress finally gets it done," Sen. Chuck Schumer (D-N.Y.) one of the members of the so-called "Gang of Eight" said during a press conference on Capitol Hill.

Five of the eight members of the group -- Schumer, Bob Menendez (D-N.J.), Dick Durbin (D-Ill.), Marco Rubio (R-Fla.), and John McCain (R-Ariz.) -- appeared at the press conference intended to outline their immigration proposal. The proposal would provide a path to citizenship for many of the nation's 11 million undocumented immigrants while upping border security and cracking down on businesses that hire workers who are not legally present in the U.S.


Sens. Jeff Flake (R-Ariz.), Lindsey Graham (R-S.C.), and Michael Bennet (D-Colo.) were the members not in attendance.


The senators all expressed optimism that their legislation could pass both the House and the Senate. Schumer added that he hopes to have an actual piece of legislation done by the end of March, and then have the Senate act on it right away.

But while some conservatives have signaled support for the Senate framework, many others have resisted any plan that could grant a pathway to citizenship to undocumented immigrants, saying it amounts to amnesty for people who broke the law.


The Senate's plan does not grant undocumented immigrants automatic "amnesty," rather it requires them to go through an arduous process that includes undergoing a background check, paying fines, back taxes and learning English and American civics over the course of a number of years. The new law would grant eligible undocumented immigrants permission to live and work in the U.S. legally, but would not confer permanent legal status, or a green card, until the border is deemed to be secure. Young people brought into the U.S. illegally as minors and some agricultural workers would face an easier path to citizenship.


"We will never put these people on a path to citizenship until we have secured the border," Schumer said.


McCain, who helped lead the last effort on a comprehensive immigration bill in 2007 said, "We have been too content for too long to allow individuals to mow our lawns, grow our food, clean our homes, and even watch our children while not affording them any of the benefits that make our country so great."


Senators in both political parties suggested that the reason that some Republicans have had a change of heart was because of the results of last November's election, when seven in 10 Latino voters backed President Barack Obama over Republican Mitt Romney.


"The politics on this issue have been turned upside down," Schumer said. "For the first time ever, there is more political risk in opposing immigration reform, than in supporting it."


Perhaps more than anyone on the stage, McCain understands this. While he backed comprehensive immigration reform five years ago, he backed away from it during his 2010 run for Senate, just as his home state was considering the SB 1070 crackdown law on undocumented immigrants.


McCain went so far as to say that the current plan is a "testimonial" to bill he worked on with Sen. Ted Kennedy (D-Mass.), the late liberal icon, in 2007.


Another member of the group, Marco Rubio, had not always voiced support for a pathway to citizenship for undocumented immigrants during his Senate career. But on Monday, he said that Congress needs to "address the reality" of the massive undocumented population in the U.S.

DNA privacy: don't flatter yourself






















The secrets contained in our individual genomes are less valuable than we like to believe
















IMAGINE donating your DNA to a project aimed at discovering links between genes and diseases. You consent to your genome sequence being released anonymously into the public domain, though you are warned there is a remote possibility that it might one day be possible to link it back to you.











A few years later, that remote possibility comes to pass. How should you feel? This is no longer a hypothetical scenario. About 50 people who participated in a project called 1000 Genomes have been traced (see "Matching names to genes: the end of genetic privacy?").













The researchers' intentions were honourable. They have not revealed these identities, and the original data has been adjusted to make a repeat using the same technique impossible. All they wanted to do was expose privacy issues.












Consider them exposed. It is clear that genomics has entered a new phase, similar to that which social media went through a few years ago, when concerns were raised about people giving away too much personal information.












What happens when the same applies to our DNA? Having your genome open to public scrutiny obviously raises privacy issues. Employers and insurers may be interested. Embarrassing family secrets may be exposed.












But overall, personal genetic information is probably no more revealing than other sorts. In fact there are reasons to believe that it is less so: would an insurance company really go to the trouble of decoding a genome to discover a slightly elevated risk of cancer or Alzheimer's disease?












The available evidence suggests not. In 2006, Harvard University set out to sequence the genomes of 100,000 volunteers and make them publicly available, along with personal information such as names and medical records. One of the goals was to see what happens when such data is open to all. The answer seems to be "not a lot". So far this Personal Genome Project has published 148 people's full genomes. Not one volunteer has reported a privacy issue.












This is not a reason for complacency, but it suggests that our genomic secrets are less interesting to other people than we might like to believe.

Nanyang Business School takes 32nd spot in world's MBA rankings






SINGAPORE: Nanyang Business School (NBS) is now ranked 32nd in the Financial Times' 2013 ranking of the world's MBA programmes, up two spots from last year.

The school's Nanyang Master of Business Administration programme is ranked sixth within the Asia Pacific.

The annual survey ranks the top 100 business schools from around the world, based on audited data from the schools themselves and from the class who graduated three years ago.

NBS admits about 80 students to its full-time MBA programme every year, with another 40 taking the course on a part-time basis.

It is offering a new Nanyang MBA curriculum in July with a a sharper focus on leadership development and industry application in the Asian context.

The new course can be completed in 12 months, instead of the usual 16.

Pornographic video clips already showing up on Twitter's Vine




Less than a week after Twitter unveiled Vine, the video-sharing app apparently has developed a porn problem.


Released Thursday, the app for iPhone and
iPod Touch lets anyone create and share six-second clips, but it also has become a popular venue for male genitalia and pornographic movies taped off TVs and laptops. As first pointed out last night by The New York Times' Nick Bilton, searches for #porn, #sex, and other associated tags brings up a handful of videos featuring male exhibitionism and other activity.


While Vine's terms of service don't expressly forbid sexually explicit content, Twitter does encourage users to use good judgment when posting content:


You are responsible for your use of the Services, for any Content you post to the Services, and for any consequences thereof. The Content you submit, post, or display will be able to be viewed by other users of the Services and through third party services and websites. You should only provide Content that you are comfortable sharing with others under these Terms.


However, Vine users can flag videos they find offensive. If clips receive enough complaints, Twitter will add a warning still to the beginning of the video that users have to bypass to see the clip, a Twitter representative told CNET.




"Uploaded videos that are reported and determined to violate our guidelines will be removed from the site, and the user that posted the video may be terminated," the representative said in a statement.


Long an advocate for freedom of expression, Twitter has been reluctant to censor tweets. A year ago, the microblogging site announced it would be willing to remove tweets on a country-by-country basis when there are local restrictions against specific content in the tweets.


While the NSFW content might not violate Twitter's TOS, Apple's App Store guidelines state that "apps containing pornographic material, defined by Webster's Dictionary as 'explicit descriptions or displays of sexual organs or activities intended to stimulate erotic rather than aesthetic or emotional feelings,' will be rejected."


Apple recently removed an app called 500px, presumably because of its photo-sharing capabilities, which might allow users to search for and find naked bodies. CNET has contacted Apple for comment and will update this report when we learn more.

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."

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, 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 started the blaze in Santa Maria, a university city of about 225,000 people, though officials said the cause was still under investigation.



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."



Guitarist Rodrigo Martins told Radio Gaucha that the band, Gurizada Fandangueira, started playing at 2:15 a.m. "and we had played around five songs when I looked up and noticed the roof was burning"



"It might have happened because of the Sputnik, the machine we use to create a luminous effect with sparks. It's harmless, we never had any trouble with it.



"When the fire started, a guard passed us a fire extinguisher, the singer tried to use it but it wasn't working"



He confirmed that accordion player Danilo Jacques, 28, died, while the five other members made it out safely.



Police Maj. Cleberson Braida Bastianello said by telephone that the toll had risen to 233 with the death of a hospitalized victim — he said earlier that the death toll was likely made worse because the nightclub appeared to have just one exit through which patrons could exit.



Officials counted 232 bodies that had been brought for identification to a gymnasium in Santa Maria, which is located at the southern tip of Brazil, near the borders with Argentina and Uruguay.



Federal Health Minister Alexandre Padhilha told a news conference that most of the 117 people treated in hospitals had been poisoned by gases they breathed during the fire. Only a few suffered serious burns, he said.



Brazil President Dilma Rousseff 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," Rousseff said.



Most of the dead apparently were asphyxiated, 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.

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.

Germany has 'everlasting responsibility' for Nazi crimes: Merkel

 





BERLIN: Germany has "an everlasting responsibility" for the crimes committed by the Nazis, Chancellor Angela Merkel said Saturday, just days ahead of the 80th anniversary of Adolf Hitler's takeover of power.

"Naturally, we have an everlasting responsibility for the crimes of national-socialism, for the victims of World War II, and above all, for the Holocaust," Merkel said in a podcast on her website.

Her remarks came as the world prepares to mark Holocaust Memorial Day on January 27, the date in 1945 when the Soviet army liberated the Auschwitz concentration camp in then occupied Poland.

In another significant date, Wednesday will mark eight decades since Hitler was appointed chancellor on January 30, 1933 by then president Paul von Hindenburg.

"We must clearly say, generation after generation, and say it again: with courage, civil courage, each individual can help ensure that racism and anti-Semitism have no chance," Merkel added.

"We're facing our history, we're not hiding anything, we're not repressing anything. We must confront this to make sure we are a good and trustworthy partner in the future, as we already are today, thankfully," she said.

In Swartz protest, Anon hacks U.S. site, threatens leaks



In response to the death of tech activist Aaron Swartz, hacktivist collective Anonymous hacked a U.S. government Web site related to the justice system and posted a screed saying it would begin leaking a cache of government documents if the justice system is not reformed.


The group hacked the Web site for the United States Sentencing Commission late Friday, posting a message about what it's calling "Operation Last Resort," along with a set of downloadable encrypted files it said contain sensitive information. The sentencing commission is the caretaker of the guidelines for sentencing in U.S. federal courts.



"Two weeks ago today, a line was crossed," the group's statement reads. "Two weeks ago today, Aaron Swartz was killed. Killed because he faced an impossible choice. 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."



The recent suicide of Swartz, a proponent of freely accessible information, has been blamed by some on what they say were outrageously aggressive efforts on the part of the U.S. Attorney in Massachusetts to punish Swartz for his alleged theft of millions of articles from a database of academic journals. The 26-year-old Swartz, who struggled with bouts of depression, had been charged with 13 felonies and threatened with decades in prison and fines exceeding $1 million. U.S. Attorney Carmin Ortiz says Swartz' lawyers were also offered a plea bargain in which he'd plead guilty and serve perhaps 6 months.


Anonymous encouraged its followers to download the files on the hacked site, a set of nine downloads named after the U.S. Supreme Court's nine justices and collectively referred to by the hacking collective as a "warhead."


"Warhead-US-DOJ-LEA-2013.AEE256 is primed and armed. It has been quietly distributed to numerous mirrors over the last few days and is available for download from this website now. We encourage all Anonymous to syndicate this file as widely as possible."


The group wouldn't specify what, exactly, is in the files, saying only that "the contents are various and we won't ruin the speculation by revealing them. Suffice it to say, everyone has secrets, and some things are not meant to be public. At a regular interval commencing today, we will choose one media outlet and supply them with heavily redacted partial contents of the file."


The contents of the encrypted files can apparently be accessed only with a decryption key, and Anonymous said it didn't necessarily want to provide that key to its followers -- it mentioned "collateral damage" as a result of any leaks and said "It is our hope that this warhead need never be detonated." But the group said the U.S. government must begin acting on reforms to the justice system suggested by the system's critics, and in spelling out its demands more specifically, it mentioned plea bargaining and suggested the overhaul of legislation such as the mid-1980s antihacking law entitled the Computer Fraud and Abuse Act.



...in order for there to be a peaceful resolution to this crisis, certain things need to happen. There must be reform of outdated and poorly-envisioned legislation, written to be so broadly applied as to make a felony crime out of violation of terms of service, creating in effect vast swathes of crimes, and allowing for selective punishment. There must be reform of mandatory minimum sentencing. There must be a return to proportionality of punishment with respect to actual harm caused, and consideration of motive and mens rea [criminal intent]. The inalienable right to a presumption of innocence and the recourse to trial and possibility of exoneration must be returned to its sacred status, and not gambled away by pre-trial bargaining in the face of overwhelming sentences, unaffordable justice, and disfavourable odds. Laws must be upheld unselectively, and not used as a weapon of government to make examples of those it deems threatening to its power.


The group said it had acquired the files by compromising various government Web sites and installing "leakware," which it has since removed to cover its tracks.



Here's the video Anon posted on the commission's site. A Google cache of the hacked home page, which includes the text version of the screed, can be seen here.
