Obama Signs Order to Begin Sequester Cuts

President Obama and congressional leaders today failed to reach a breakthrough to avert a sweeping package of automatic spending cuts, setting into motion $85 billion of across-the-board belt-tightening that neither had wanted to see.

President Obama officially initiated the cuts with an order to agencies Friday evening.

He had met for just over an hour at the White House Friday morning with Republican leaders House Speaker John Boehner and Senate Minority Leader Mitch McConnell and his Democratic allies, House Minority Leader Nancy Pelosi, Senate Majority Leader Harry Reid and Vice President Joe Biden.

But the parties emerged from their first face-to-face meeting of the year resigned to see the cuts take hold at midnight.

"This is not a win for anybody," Obama lamented in a statement to reporters after the meeting. "This is a loss for the American people."

Officials have said the spending reductions immediately take effect Saturday but that the pain from reduced government services and furloughs of tens of thousands of federal employees would be felt gradually in the weeks ahead.

Federal agencies, including Homeland Security, the Pentagon, Internal Revenue Service and the Department of Education, have all prepared to notify employees that they will have to take one unpaid day off per week through the end of the year.

The staffing trims could slow many government services, including airport screenings, air traffic control, and law enforcement investigations and prosecutions. Spending on education programs and health services for low-income families will also get clipped.

"It is absolutely true that this is not going to precipitate the crisis" that would have been caused by the so-called fiscal cliff, Obama said. "But people are going to be hurt. The economy will not grow as quickly as it would have. Unemployment will not go down as quickly as it would have. And there are lives behind that. And it's real."

The sticking point in the debate over the automatic cuts -- known as sequester -- has remained the same between the parties for more than a year since the cuts were first proposed: whether to include more new tax revenue in a broad deficit reduction plan.

The White House insists there must be higher tax revenue, through elimination of tax loopholes and deductions that benefit wealthier Americans and corporations. Republicans seek an approach of spending cuts only, with an emphasis on entitlement programs. It's a deep divide that both sides have proven unable to bridge.

"This discussion about revenue, in my view, is over," Boehner told reporters after the meeting. "It's about taking on the spending problem here in Washington."

Boehner: No New Taxes to Avert Sequester

Boehner says any elimination of tax loopholes or deductions should be part of a broader tax code overhaul aimed at lowering rates overall, not to offset spending cuts in the sequester.

Obama countered today that he's willing to "take on the problem where it exists, on entitlements, and do some things that my own party doesn't like."

But he says Republicans must be willing to eliminate some tax loopholes as part of a deal.

"They refuse to budge on closing a single wasteful loophole to help reduce the deficit," Obama said. "We can and must replace these cuts with a more balanced approach that asks something from everybody."

Can anything more be done by either side to reach a middle ground?

The president today claimed he's done all he can. "I am not a dictator, I'm the president," Obama said.

Mystery ring of radiation briefly encircled Earth

What were you doing last September? The charged particles that dance around Earth were busy. Unbeknown to most earthlings, a previously unseen ring of radiation encircled our planet for nearly the whole month – before being destroyed by a powerful interplanetary shock wave.

We already knew that two, persistent belts of charged particles, called the Van Allen radiation belts, encircle Earth. The discovery of a third, middle ring by NASA's twin Van Allen probes, launched in August 2012, suggests that these belts, which have puzzled scientists for over 50 years, are even stranger than we thought. Working out what caused the third ring to develop could help protect spacecraft from damaging doses of radiation.

Charged particles get trapped by Earth's magnetic field into two distinct regions, forming the belts. The inner belt, which extends from an altitude of 1600 to 12,900 kilometres, is fairly stable. But the outer belt, spanning altitudes ranging from 19,000 to 40,000 kilometres, can vary wildly. Over the course of minutes or hours, its electrons can be accelerated to close to the speed of light, and it can grow to 100 times its usual size.

Mystery acceleration

No one is sure what causes these "acceleration events", although it seems to have something to do with solar activity interacting with the Earths' magnetic field.

"That's one of the key things the probes are in place to understand," says Dan Baker of the University of Colorado, Boulder. "How does this cosmic accelerator, operating just a few thousand miles above our head, accelerate electrons to such extraordinarily high energies?"

When the Van Allen probes started taking data on 1 September 2012, one of these mysterious events was already under way. "We came in the middle of the movie there," Baker says. But otherwise, he says, "What we expected was what we saw when we first turned on: two distinct belts, separated."

That changed a day later when, to the team's surprise, an extra ring developed between the inner and outer ones. "We watched it develop right before our eyes," Baker says. The new, middle ring was relatively narrow, and its electrons had energies between 4 and 7.5 megaelectronvolts - about the same as in the outer Van Allen belt during an acceleration event.

Although the outer ring displayed its characteristic inconstancy, the new middle ring barely budged for nearly four weeks. Then a shock wave, probably linked to a burst of solar activity, wiped it out in less than an hour on 1 October.

Spacecraft malfunctions

It's not clear where the middle ring came from, Baker says, although it was probably related to the acceleration event. The electrons could have been stripped from the outer Van Allen belt, funnelled back towards the Earth and got trapped in the middle on the way, or they could have been energised from closer to Earth and shot up to higher altitudes.

Figuring out what happened could be important to protecting spacecraft from radiation damage, says Yuri Shprits of the University of California in Los Angeles, who was not involved in the observations but is crafting a theoretical explanation that he hopes to publish soon. "It truly presents us with a very important question, and very important puzzles," he says.

There were no specific spacecraft malfunctions during September that can be directly linked to the new belt, says Shprits. However satellite operators will want to know if such belts are common and if they pose more of a risk.

With no other examples of a transient belt caught so far, it's too soon to answer all those questions, Baker says. "We only have one in captivity," he says. "We're still trying to figure out exactly how it works."

Shark fin-hungry China drives "chaotic" fishing in Indonesia

BENOA, Indonesia: Dozens of weary Indonesian fishermen sail into a busy port on the resort island of Bali celebrating their lucrative and controversial haul that is destined to end up at Chinese banquets.

The fishermen show off about 100 shark fins, already sliced off the carcasses, that are ready to be sold to middle-men and then most likely onwards to mainland China or cities around the world with big Chinese populations.

"We don't only look for sharks -- we mainly catch tuna and marlin -- but finding sharks is a good bonus. Their fins are worth a lot and the meat is easy to sell locally," said 33-year-old Warsito, who goes by one name.

Fishermen around Bali sell shark fins fresh off the boat for between US$15 and US$50, helping to satiate an ancient but fast-growing Chinese appetite for soup in which it is the main ingredient.

Shark fin soup was once a delicacy for China's elite, but shark populations have been decimated around the world as the country's 1.3 billion people have grown wealthier and incorporated it into their festivities.

While the Chinese government has banned shark fin soup from state banquets, and some five-star restaurants in Hong Kong and Singapore have dropped it from their menus, a burgeoning middle class in China continues to stoke demand.

Humans kill about 100 million sharks each year, mostly for their fins, according to the UN Food and Agriculture Organisation (FAO), and conservationists are warning that dozens of species are under threat.

Ninety percent of the world's sharks have disappeared over the past 100 years, mostly because of overfishing in countries such as Indonesia, the FAO said.

Conservationists also point out that "finning" -- slicing the valuable fins from live sharks -- is simply inhumane, as the rest of the animal is typically dumped back into the ocean where it bleeds slowly to death.

How to save the shark will be a top concern at the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) that begins in Bangkok, Thailand, on Sunday.

World authorities will look at restricting trade of certain shark species.

Restrictions would apply to manta rays and five shark species -- the porbeagle, scalloped hammerhead, great hammerhead, smooth hammerhead and oceanic whitetip -- and must be approved by two-thirds of member states.

However, experts say laws to restrict trade will mean little unless there are total bans on fishing, with greater efforts needed to control unregulated fisheries.

Indonesia is particularly important because it is the world's biggest fisher and exporter of sharks, with thousands of small-time fishermen such as those in Bali able to operate with impunity.

Management of the Indonesian industry has been "total chaos", Conservation International Indonesia marine programme director Tiene Gunawan said, with no national restrictions on the trade.

In 2010, the Indonesian government designed a national plan of action to better manage the shark fishing industry, but it has so far issued no regulations.

Rampant shark fishing has already affected ecosystems in Indonesian waters, Gunawan said, including the world-famous diving spot Raja Amapat in the region of Papua.

However recent efforts by the provincial authorities there -- emanating from a recognition that there is greater economic benefit in maintaining shark populations -- could be a model for the future.

After authorities in Raja Ampat noticed a surge in boats carrying hundreds of shark fins but no carcasses, the local government banned shark fishing in 2010.

Last week the ban was made into law, creating the country's only shark and manta ray sanctuary. It is also the first in the Coral Triangle, a massive region in Southeast Asia known as the "Amazon of the ocean".

"What they realised, and our studies support this, is that the value of a dead shark is much lower than if we keep it alive for tourism," Gunawan said.

Vatican deletes Pope Benedict XVI tweets from @Pontifex

The Vatican has deleted all tweets posted under Pope Benedict XVI on the @Pontifex Twitter account.

Benedict's tweets have been archived on the Vatican's website and the @Pontifex account holder's name has been changed "Sede Vacante" -- an expression to signify the papacy is currently vacant. The tweets will be filed under the name Pope Benedict XVI -- his official post-retirement title is Pope Emeritus.

Benedict posted his last tweet at 11 a.m. ET as he prepared to leave the Vatican for Castel Gandolfo, where he will spend the next chapter of his life. Benedict's final message to fans said: "Thank you for your love and support. May you always experience the joy that comes from putting Christ at the centre of your lives."

The Vatican reported earlier that Benedict would send his last tweet as pope around 5 p.m. Rome time (1600 GMT, 11 a.m. EST). That's also about the time he left the Vatican by helicopter to the papal retreat at Castel Gandolfo.

Vatican spokesman the Rev. Federico Lombardi says the pope's Twitter handle @Pontifex will then be "in abeyance" until the next pontiff is selected. He says it'll be up to the next leader of the Catholic Church as to whether or not he will use it

The pope sent his first tweet in 2011 from a Vatican account to launch the Holy See's news information portal. But in the wake of the Church's maligned handling of the child sexual abuse scandal, the Vatican hand-picked Fox News journalist Greg Burke to be its new communications adviser, and with his guidance, it launched Benedict's own account.

Burke told a press conference in December 2012 -- announcing the new social media initiative as an effort to reach out to a younger audience -- that @Pontifex was chosen for the pope's account because it not only means pope in Latin, but also bridge-builder, suggesting unity.

Benedict garnered some 1.5 million Twitter followers in just six weeks. Vatican officials have acknowledged the pope did not actually type the Twitter messages and that someone in the Vatican's secretariat of state writes them on his behalf.

In January, the pope used the account to give a shout-out to an anti-abortion rally in Washington, tweeting that politicians should protect the unborn and "promote a culture of life."

Arias Recounts Each Moment of Stabbing, Slashing

Accused murderer Jodi Arias was forced to recount today each detail of how she killed her ex-boyfriend, Travis Alexander, including re-enacting how he allegedly tackled her when she shot him, leaving her crying in her hands on the witness stand.

During hours of dramatic cross-examination by prosecutor Juan Martinez, Arias bawled as he asked her about stabbing, slashing and shooting Alexander on June 4, 2008.

"You would acknowledge that Mr. Alexander was stabbed, and that the stabbing was with the knife, and it was after the shooting according to you, right?" Martinez said in rapid succession.

"Yes, I don't remember," Arias said, covering her face with her hands.

"Do you acknowledge the stab wounds, and we can count them together, were to the back of the head and the torso?" Martinez said, flashing a photo of Alexander's bloodied body onto the courtroom projector. " Do you want to take a look at the photo?"

Arias, burying her face in her hands and shutting her eyes on the stand, mumbled, "No."

Alexander's sisters, seated in the front row of the gallery, also looked away, crying.

Arias, 32, is accused of killing Alexander on June 4, 2008 out of jealousy. He was stabbed 27 times, his throat was slashed and he was shot in the head twice.

Arias claims she killed in self-defense after Alexander had become increasingly violent with her. She could face the death penalty if convicted.

Martinez also forced Arias to demonstrate in court today how she claims Alexander lunged at her "like a linebacker," causing her to fire the gun at him. The pair argued over how exactly Alexander was positioned, and Martinez pushed her to explain what she meant.

"He lunges at me like a linebacker," Arias said.

"Like a linebacker, what does that mean?" Martinez asked.

"He was low. It was almost like he dove," she said, and trying to explain it further, added, "He was like a linebacker is the only way I can describe it unless I get up to act it out which I'd rather not do."

Timeline of the Jodi Arias Trial

"Go ahead and do it," Martinez said. "Just stand. Go ahead."

Judge Sherry Stephens initially cleared the court as Arias demonstrated and then Martinez had her do it again after the jury and spectators were allowed back into the courtroom.

Standing and moving away from the witness box, Arias bent at the waist and spread out her arms and meekly made a slight lunging motion.

According to her testimony, Arias fired the gun as Alexander rushed at her, tackling her to the ground. She said she does not remember how she stabbed or slashed him.

It was a day of dramatics and anger as the prosecution pressed Arias on the details of the killing, with Martinez ending the afternoon of questioning by accusing Arias of lying throughout her direct testimony.

At one point Arias dissolved into tears, unable to answer pointed questions when shown a photo of Alexander's body lying crumpled in the bottom of the stall shower.

After a short pause, Martinez asked dryly, "Were you crying when you were shooting him?"

"I don't remember," Arias moaned.

"Were you crying when you stabbed him?" he said. "How about when you slashed his throat?"

"I don't remember, I don't know."

Martinez pressed on, "You're the one that did this right? And lied about all this right?"

"Yes."

"So then take a look at it," he barked.

Arias did not answer Martinez's question, crying into her hands instead. The judge, after a moment, called for the lunch recess to take a break from the testimony. Arias' attorney walked over and consoled her, telling her to "take a moment."

Until that moment, Arias had given vague answers to Martinez as he asked about the hours leading up to the murder. Arias, 32, has testified that she drove to Alexander's house on June 4, 2008, for a sexual liaison, that she had sex with Alexander and the pair took nude photos before an explosive confrontation ended with her killing him. She claims she doesn't remember stabbing Alexander, but insists it was in self-defense.

Martinez questioned her claims, asking exactly what they argued about and who encouraged whom to take the nude photos. He pointed out that Arias told Detective Esteban Flores of the Mesa police department that she had to convince Alexander to take the nude photos in the shower, but that she testified on the stand that Alexander had wanted them.

Quantum skyfall puts Einstein's gravity to the test

DIVIDING a falling cloud of frozen atoms sounds like an exotic weather experiment. In fact, it's the latest way to probe whether tiny objects obey Einstein's theory of general relativity, our leading explanation for gravity.

General relativity is based on the equivalence principle, which says that in free fall, all objects fall at the same rate, whatever their mass, provided the only force at work is gravity. That has been proven for large objects: legend has it that Galileo did it first by dropping various balls from the Tower of Pisa. Whether equivalence holds at quantum scales, where gravity's effects are not well understood, isn't clear. Figuring it out could help create a quantum theory of gravity, one of the biggest goals of modern physics.

Creating a quantum equivalent of Galileo's test isn't easy. In 2010 a team led by Ernst Rasel of the University of Hannover in Germany monitored a quantum object in free fall, by tossing a Bose-Einstein condensate (BEC) – a cloud of chilled atoms that behaves as a single quantum object and so is both particle and wave – down a 110-metre tall tower. Now they have split and recombined the wave – all before the BEC, made of rubidium atoms, reached the bottom. This produces an interference pattern that records the path of the falling atoms and can be used to calculate their acceleration (Physical Review Letters, doi.org/km6). The next step is to do the same experiment on a different kind of atom, with a different mass, to see if the equivalence principle holds.

The BEC can only be split for 100 milliseconds in the tower before hitting the bottom, so to allow tiny differences between the atom types to emerge, the work must be repeated in space, where the waves can be split for longer. By showing that a matter-wave can be split and recombined while falling, Rasel's result is a "major step" towards the space version, says Charles Wang of the University of Aberdeen, UK.

Yvonne Lim: Making time for love

SINGAPORE: Her eyes glistened with tears when Singapore actress Yvonne Lim spoke about her character Liu Xixi in the upcoming drama "Marry Me", during a recent media event.

In the show, Liu, a successful gynecologist, winds up getting dumped by her boyfriend of 20 years, after she spent too much time on her career and neglected their relationship.

Lim revealed that she became emotional as her character's painful experiences in "Marry Me" reminded her of own.

"I have all these experiences before."

"I spend so much of my time on my work that I end up spending very little time dealing with matters of the heart," said Lim, explaining that she once broke up with a guy over the same issue.

"I remember I was very emotional when I read the script."

"I know how this character feels, why she struggles with her feelings, and why she is in pain, but keeps it bottled up inside."

Lim expressed that Liu is a character many women can identify with, because what happens to her in the show is something that also occurs in real life.

"She is so dedicated to her work that she forgot about her love life and kind of took it for granted.

"I've seen that happen to my girl friends. I have seen that happen to other people. I've heard stories like that before."

"When things drag on for too long, it (the relationship) gets stagnant. That's when things happen," said Lim earnestly.

Still, Lim said she prefers to take her time to slowly get to know someone instead of rushing things, and said she believes in "letting nature take its course".

"You have to find the right partner who is willing to be with you.

"If it happens, it happens. If not, that's the way it is," said Lim with a smile.

"I don't think about it much, though there is still this part of me that hopes for a fairytale ending."

"Marry Me", which also stars Koh Ya Hui and Jesseca Liu, airs every Wednesday, Thursday and Friday, 8pm on Channel U.

Federal budget cuts free illegal immigrants from detention

(CBS News) -- The federal budget cuts expected to take effect this Friday are not simple. For example, hundreds of illegal immigrants are being released from detention because the administration says it can't afford to keep them.

Until recently, Fredi Alcazar was one of those detained. An illegal immigrant from Mexico, Alcazar spent a month in jail after a traffic stop near Atlanta last December. He now wears an electronic monitoring band on his ankle. The device lets immigration officials know where he is at all times.

(watch: Releasing illegal immigrants over budget cuts, below)

Alcazar was released unexpectedly in January.

"I was surprised they released me," Alcazar recalled. "They didn't say anything."

Officials at Immigration and Customs Enforcement (ICE) would not tell CBS exactly how many detainees they released ahead of for Friday's automatic budget cuts. They also declined to say where or when the releases occurred.

Those let go, like Fredi Alcazar, are required to wear electronic tracking devices, regularly call immigration officials or visit ICE offices.

"We started getting calls all of a sudden they had been released," said immigration advocate Dulce Guerrero. "We were very much in shock."

The early release of detainees was a surprise to Guerrero.

"These folks are no criminals," she said. "These folks in there are moms, dads, students, community members who are in there for no license, for a broken tail light."

But some members of Congress are demanding ICE provide information on each detainee's case.

"When you release these people and expect them to show up at a court proceeding at a later date, we found before that 90 percent of them don't show up," said Congressman Michael McCaul, chair of the House Homeland Security Committee.

Besides Georgia, CBS did learn that many releases were in Arizona, California and Florida. Immigration advocates said that "supervised release" costs about $14 a day compared to about $160 a day to keep detainees in jail.
