Weird high-energy flare made by spitting black hole


































GLOBS of plasma spat out by black holes can trigger the brightest flashes of lightMovie Camera in the universe.













Gamma-ray bursts are high-energy flares that mostly originate billions of light years away, making it hard to see how they are created. In November 2011, NASA's Fermi satellite saw a gamma-ray burst coming from the galaxy 4C +71.07, which sits about 10.5 billion light years away. The galaxy was also being watched by the Very Long Baseline Array, a radio telescope network that can see small features at a distance.












The supermassive black hole at the galaxy's centre is feeding on surrounding matter, causing it to fire high-speed jets of particles. The radio array showed that, around the same time as the flare, the black hole spat out a knot of plasma that travelled up the jet at near the speed of light.












Electrons in the knot probably collided with and energised light from a slower-moving part of the jet, producing the gamma rays, says Alan Marscher of Boston University, who presented the work at a recent astronomy meeting in California. It's still a mystery, though, what made the black hole erupt.

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."

DNA in stolen kisses could reveal sex offenders








































SO ROMANTIC... when you kiss your partner passionately, not only do you exchange bacteria and mucus, you also impart some of your genetic code. No matter how fleeting the encounter, the DNA will hang around in their mouth for at least an hour. This means that women's saliva could contain evidence of unwanted attention in cases of assault, or even telltale signs of infidelity.













Natália Kamodyová and her colleagues at Comenius University in Bratislava, Slovakia, recruited 12 couples who agreed to kiss each other passionately for at least 2 minutes. Afterwards, saliva samples were collected from the women at 5, 10, 30 and 60-minute intervals. Because Kamodyová's method relies on detection of the Y chromosome, it can only be used to identify a man's DNA in a woman's saliva.











The results show that the man's DNA was still present and could be detected through amplification after at least an hour, and possibly longer. "We've shown it's possible to get a full profile, which could be useful in crime investigation to pinpoint the possible perpetrator among suspects or exclude those innocent," says Kamodyová. Her team is investigating whether the DNA survives longer than an hour and whether it's obtainable from the mouths of women who have died (Forensic Science International: Genetics, DOI: 10.1016/j.fsigen.2012.07.007).

Tennis: Azarenka beats Li in dramatic Australian final






MELBOURNE: Victoria Azarenka won an incident-packed final against an injury-hit Li Na to successfully defend her Australian Open title and retain the world number one ranking on Saturday.

After a scrappy match marked by boos for Azarenka, a break for Australia Day fireworks and two painful falls for China's Li, the Belarusian top seed dissolved in tears after sealing the 4-6, 6-4, 6-3 win.

Li required two medical timeouts, when she twice twisted her left ankle and also banged her head on the court, in a match also interrupted for nine minutes at a crucial stage by the fireworks.

Azarenka overcame a pro-Li crowd that was clearly unimpressed by her controversial medical timeout in the semi-finals, which she took after blowing five match points.

It was a gutsy effort from the 23-year-old as she came back from a set down and sealed it on her first match point in 2hr 40min to clinch her second Grand Slam title.

Azarenka became only the fourth active player to hold two or more majors, behind Serena Williams with 15, Venus Williams with seven, Maria Sharapova with four and Svetlana Kuznetsova with two.

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



Ashton Kutcher as Steve Jobs in "jOBS."

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."

WH, Senators to Begin Push on Immigration Reform












The White House and a bipartisan group of senators next week plan to begin their efforts to push for comprehensive immigration reform.


President Barack Obama will make an announcement on immigration during a Tuesday trip to Las Vegas, Nevada, the White House said on Friday. The Senate group is expected make their plans public around the same time, the Associated Press reported.

For Obama, immigration reform is a campaign promise that has remained unfulfilled from his first White House run in 2008. During his 2012 re-election campaign, the president vowed to renew his effort to overhaul the nation's immigration system. It has long been expected that Obama would roll out his plans shortly after his inauguration.


The president's trip to Las Vegas is designed "to redouble the administration's efforts to work with Congress to fix the broken immigration system this year," the White House said.


Ever since November's election, in which Latino voters turned out in record numbers, Republicans and Democrats have expressed a desire to work on immigration reform. Obama has long supported a bill that would make many of the nation's 11 million undocumented immigrants without criminal records eligible to apply for an earned pathway to citizenship, which includes paying fines and learning English.

But the debate over a pathway to citizenship is expected to be contentious. Other flashpoints in an immigration reform push could include a guest-worker program, workplace enforcement efforts, border security, and immigration backlogs.


In a statement, the White House said that "any legislation must include a path to earned citizenship."


Ahead of his immigration push next week, Obama met today with a group of lawmakers from the Congressional Hispanic Caucus (CHC), including chairman Rubén Hinojosa (D-Texas) , Sen. Bob Menendez (D-N.J.), Democratic Caucus Chair Rep. Xavier Becerra (D-Calif.), and CHC Immigration Task Force Chair Rep. Luis Gutierrez (D-Ill.), the latter's office said. CHC members are expected to play a pivotal role in the debate.


"The president is the quarterback and he will direct the team, call the play, and be pivotal if we succeed. I am very optimistic based on conversations with Republicans in the House and Senate that we will do more than just talk about the immigration issue this year," Gutierrez said in a statement following the CHC meeting with Obama. "The president putting his full weight and attention behind getting a bill signed into law is tremendously helpful. We need the president and the American people all putting pressure on the Congress to act because nothing happens in the Capitol without people pushing from the outside."


A bipartisan group of eight senators, which includes Menendez, has also begun talks on drafting an immigration bill and will play an integral part in the process of passing a bill through Congress. Sen. Marco Rubio (R-Fla.), who has been participating in talks with others senators, has also unveiled his own outline for an immigration proposal.


The group of senators have reportedly eyed Friday as the date when they'll unveil their separate proposal, according to the Washington Post.
