Black Hole Spins at Nearly the Speed of Light

A superfast black hole nearly 60 million light-years away appears to be pushing the ultimate speed limit of the universe, a new study says.

For the first time, astronomers have managed to measure the rate of spin of a supermassive black hole—and it's been clocked at 84 percent of the speed of light, or the maximum allowed by the law of physics.

"The most exciting part of this finding is the ability to test the theory of general relativity in such an extreme regime, where the gravitational field is huge, and the properties of space-time around it are completely different from the standard Newtonian case," said lead author Guido Risaliti, of the Harvard-Smithsonian Center for Astrophysics (CfA) and INAF-Arcetri Observatory in Italy. (Related: "Speedy Star Found Near Black Hole May Test Einstein Theory.")

Notorious for ripping apart and swallowing stars, supermassive black holes live at the center of most galaxies, including our own Milky Way. (See black hole pictures.)

They can pack the gravitational punch of many million or even billions of suns—distorting space-time in the region around them, not even letting light to escape their clutches.

Galactic Monster

The predatory monster that lurks at the core of the relatively nearby spiral galaxy NGC 1365 is estimated to weigh in at about two million times the mass of the sun, and stretches some 2 million miles (3.2 million kilometers) across-more than eight times the distance between Earth and the moon, Risaliti said. (Also see "Black Hole Blast Biggest Ever Recorded.")

Risaliti and colleagues' unprecedented discovery was made possible thanks to the combined observations from NASA's high-energy x-ray detectors on its Nuclear Spectroscopic Telescope Array (NuSTAR) probe and the European Space Agency's low-energy, x-ray-detecting XMM-Newton space observatory.

Astronomers detected x-ray particle remnants of stars circling in a pancake-shaped accretion disk surrounding the black hole, and used this data to help determine its rate of spin.

By getting a fix on this spin speed, astronomers now hope to better understand what happens inside giant black holes as they gravitationally warp space-time around themselves.

Even more intriguing to the research team is that this discovery will shed clues to black hole's past, and the evolution of its surrounding galaxy.

Tracking the Universe's Evolution

Supermassive black holes have a large impact in the evolution of their host galaxy, where a self-regulating process occurs between the two structures.

"When more stars are formed, they throw gas into the black hole, increasing its mass, but the radiation produced by this accretion warms up the gas in the galaxy, preventing more star formation," said Risaliti.

"So the two events—black hole accretion and formation of new stars—interact with each other."

Knowing how fast black holes spin may also help shed light how the entire universe evolved. (Learn more about the origin of the universe.)

"With a knowledge of the average spin of galaxies at different ages of the universe," Risaliti said, "we could track their evolution much more precisely than we can do today."

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.

Sequester Countdown: The Reality of Budget Cuts Watch Video

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.

Deadline for benefits e-payments is here

It took 17 years, but Friday marks the deadline to switch federal benefit checks to electronic payments, an initiative Treasury Department officials say will save up to $1 billion over a decade.

In 1996, Congress enacted a law that required all federal payments except tax refunds to be issued electronically by 1999. By December 1998, 75 percent of Social Security payments were being made through direct deposit. Today, 94 percent of Social Security and Supplemental Security Income recipients use direct deposit, said Walt Henderson, director of the Treasury’s electronic fund transfer strategy.

As of May 2011, all new applicants for federal benefits are required to choose an electronic payment method. Those receiving Social Security payments, supplemental security income and veterans benefits have the option of receiving funds by direct deposit to a bank or credit union or on a pre-loaded debit card.

But those who haven’t gone digital won’t be kicked off the rolls, Henderson said, noting they will continue to receive paper checks in the mail. There’s also a chance to apply for a waiver to the paperless requirement if circumstances require it, he said.

The Treasury has not set a date for the permanent termination of paper checks, he said.

The agency didn’t reach its near 100 percent compliance without resistance from members of the check-cashing industry.

People without bank accounts who use check-cashing services may also be hesitant to make the switch, said Edward D’Alessio, general counsel for the Financial Service Centers of America, a trade organization that represents financial-service-center providers.

“The population in this country that is un-banked has concentrations in racial and ethnic minorities and the elderly,” he said. “These are people who may have never been into a bank before. We’re in the neighborhoods, we speak the languages and we’re open extended hours.”

The industry will take a financial hit as paper checks disappear.

“There’s not much that can be done,” said Robert Frimet, the president of a money-service business-consulting firm in Las Vegas. “We’re slowly working our way to a check-free society.”

A check-free society might pose problems for seniors uncomfortable with technology, D’Alessio said, though there has not been much outcry from seniors.

Cristina Martin Firvida, the director of financial security and consumer affairs at AARP, said, “To date, we have not yet heard from a lot of our members that this is a big area of concern or that they want more information or guidance.”

The National Committee to Preserve Social Security and Medicare agreed.

“Irrespective of age, it’s so much more secure than delivery of a paper check,” said Web Phillips, the senior legislative representative for the advocacy group. “If a problem comes up . . . it’s much easier to fix than if a check is lost in the mail.”

Beneficiaries are 125 times as likely to have a problem with a paper check as with an electronic payment, according to written testimony from the Treasury at a Ways and Means Committee hearing in September.

Some exemptions are automatic, Henderson said. People over 90 will automatically continue to receive paper checks without requesting a waiver.

Others eligible for waivers include the mentally incapacitated, people in remote locations without access to banks or ATMs and people who cannot receive electronic payments for religious reasons.

Check recipients can sign up for direct deposit or the Direct Express debit card by calling 800-333-1795.

The Direct Express card was specifically designed for un-banked federal benefit recipients, Henderson said. There is no application or monthly fee. The card can be used to pay bills, make purchases and receive cash back. It is accepted anywhere MasterCard is taken.

“These are benefit payments people depend on, and we want to make sure we deliver them in the safest manner possible,” Henderson said. “Now it’s all about compliance and getting people switched over. It’s about getting them to take the action.”

Needy families on public assistance scheme to get higher payouts

SINGAPORE: From April, Public Assistance (PA) recipients can look forward to a higher level of assistance that is flexible and customised to their needs.

The Ministry of Social and Family Development (MSF) will enhance the PA scheme by providing additional assistance, other than a higher direct cash handout.

The change will mainly benefit those with special or once-off needs.

For example, additional assistance will be given to those who need healthcare and hygiene products such as adult diapers and nutritional milk supplements, or those who need once-off purchase or replacement of equipment such as a commode.

The ministry expects about one-third of existing PA households to benefit from the additional forms of assistance.

There are currently over 3,000 households on public assistance.

The cash assistance for all PA households will also be increased. The increase will range from S$50 per month for a one-person PA household to S$130 per month for a four-person PA household.

PA families with dependent children will continue to receive additional cash assistance of S$150 per child.

The ministry also added that the revision is part of the regular review of basic cash assistance rates to ensure that they are adequate to meet the needs of PA households.

Sariska villagers block tourists’ entry

ALWAR: About 2,500 villagers on Thursday blocked the main entrance of the Sariska Tiger Reserve, protesting their relocation from areas near the sanctuary.

Sariska field director RS Shekhawat said the villagers had locked the entrance and didn't allow tourists to enter the park. "We are trying to sort out the problem on a priority basis," Shekhawat said.

The villagers, who are on an indefinite sit-in, said they would not clear the blockade unless their demands were met. This is the third such protest in the past eight months against the relocation plan.

Tension began in Sariska when about 2,500 people from 50 villages gathered for a mahapanchayat against the alleged "cheating" by the district administration. "We had called off the agitation in May last year when the district administration agreed on some of our demands including lifting ban on the registry of land, construction of a concrete road and earmarking a grazing area. But now they have backtracked on the promise citing the Supreme Court orders," said Jaikishan Gujjar, a villager.

Since 2008, the farmers in the periphery of the reserve have been protesting the state government and wildlife authorities' decision to relocate them. On February 20, villagers thrashed a few senior sanctuary officials when 70 cattle were seized while grazing in the sanctuary area.

Scarred Duckbill Dinosaur Escaped T. Rex Attack

A scar on the face of a duckbill dinosaur received after a close encounter with a Tyrannosaurus rex is the first clear case of a healed dinosaur wound, scientists say.

The finding, detailed in the current issue of the journal Cretaceous Research, also reveals that the healing properties of dinosaur skin were likely very similar to that of modern reptiles.

The lucky dinosaur was an adult Edmontosaurus annectens, a species of duckbill dinosaur that lived in what is today the Hell Creek region of South Dakota about 65 to 67 million years ago. (Explore a prehistoric time line.)

A teardrop-shaped patch of fossilized skin about 5 by 5 inches (12 by 14 centimeters) that was discovered with the creature's bones and is thought to have come from above its right eye, includes an oval-shaped section that is incongruous with the surrounding skin. (Related: "'Dinosaur Mummy' Found; Have Intact Skin, Tissue.")

Bruce Rothschild, a professor of medicine at the University of Kansas and Northeast Ohio Medical University, said the first time he laid eyes on it, it was "quite clear" to him that he was looking at an old wound.

"That was unequivocal," said Rothschild, who is a co-author of the new study.

A Terrible Attacker

The skull of the scarred Edmontosaurus also showed signs of trauma, and from the size and shape of the marks on the bone, Rothschild and fellow co-author Robert DePalma, a paleontologist at the Palm Beach Museum of Natural History in Florida, speculate the creature was attacked by a T. rex.

It's likely, though still unproven, that both the skin wound and the skull injury were sustained during the same attack, the scientists say. The wound "was large enough to have been a claw or a tooth," Rothschild said.

Rothschild and DePalma also compared the dinosaur wound to healed wounds on modern reptiles, including iguanas, and found the scar patterns to be nearly identical.

It isn't surprising that the wounds would be similar, said paleontologist David Burnham of the University of Kansas Biodiversity Institute, since dinosaurs and lizards are distant cousins.

"That's kind of what we would expect," said Burnham, who was not involved in the study. "It's what makes evolution work—that we can depend on this."

Dog-Eat-Dog

Phil Bell, a paleontologist with the Pipestone Creek Dinosaur Initiative in Canada who also was not involved in the research, called the Edmontosaurus fossil "a really nicely preserved animal with a very obvious scar."

He's not convinced, however, that it was caused by a predator attack. The size of the scar is relatively small, Bell said, and would also be consistent with the skin being pierced in some other accident such as a fall.

"But certainly the marks that you see on the skull, those are [more consistent] with Tyrannosaur-bitten bones," he added.

Prior to the discovery, scientists knew of one other case of a dinosaur wound. But in that instance, it was an unhealed wound that scientists think was inflicted by scavengers after the creature was already dead.

It's very likely that this particular Edmontosaurus wasn't the only dinosaur to sport scars, whether from battle wounds or accidents, Bell added.

"I would imagine just about every dinosaur walking around had similar scars," he said. (Read about "Extreme Dinosaurs" in National Geographic magazine.)

"Tigers and lions have scarred noses, and great white sharks have got dings on their noses and nips taken out of their fins. It's a dog-eat-dog world out there, and [Edmontosaurus was] unfortunately in the line of fire from some pretty big and nasty predators ... This one was just lucky to get away."

Mysterious Escape

Just how Edmontosaurus survived a T. rex attack is still unclear. "Escape from a T. rex is something that we wouldn't think would happen," Burnham said.

Duckbill dinosaurs, also known as Hadrosaurs, were not without defenses. Edmontosaurus, for example, grew up to 30 feet (9 meters) in length, and could swipe its hefty tail or kick its legs to fell predators.

Furthermore, they were fast. "Hadrosaurs like Edmontosaurus had very powerful [running] muscles, which would have made them difficult to catch once they'd taken flight," Bell said.

Duckbills were also herd animals, so maybe this one escaped with help from neighbors. Or perhaps the T. rex that attacked it was young. "There's something surrounding this case that we don't know yet," Burnham said.

Figuring out the details of the story is part of what makes paleontology exciting, he added. "We construct past lives. We can go back into a day in the life of this animal and talk about an attack and [about] it getting away. That's pretty cool."

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.

House to vote on Violence Against Women Act measures

Seeking to avoid a protracted and politically damaging fight over reauthorization of the Violence Against Women Act, Republican leaders are prepared to allow the House to vote Thursday on a version of the bill favored by Democrats, an unusual move that acknowledges GOP divisions on the touchy issue.

The House will vote first on a Republican version of the bill, which authorizes funding for programs to aid prosecution of domestic violence and sexual assault cases and assist victims.

But with Democrats unified in opposition and Republicans divided, the GOP’s alternative appears likely to fail.

The House would then move to a vote on a version adopted by the Senate this month on a broadly bipartisan 78 to 22 vote. It broadens the bill’s protections to gays and lesbians and expands the authority of tribal courts to prosecute non-native Americans accused in domestic violence cases on Indian reservations. It is supported by the White House and domestic violence advocates.

That bill is expected to pass on the strength of votes from Democrats and some Republicans — and over objections from a bloc of conservatives, an increasingly common pathway for successful legislation in a House roiled by divisions inside the GOP majority.

The outcome would send the Senate bill to President Obama for his signature, reauthorizing the landmark measure which has been credited with raising awareness of the problems of violence against women since it was first enacted in 1994.

“The majority of the country feels strongly this is something we ought to do,” said Rep. Tom Cole (R-Okla.), a Native American. He prefers the Senate bill because of how it would deal with crimes committed on Indian reservations. “It’s better to resolve this and move on, rather than be hung up on the issue.”

VAWA has been reauthorized on noncontroversial and bipartisan votes twice.

But a third reauthorization stumbled on a partisan dispute last year after the House adopted a Republican bill in response to opposition expansions in VAWA’s protections that had been adopted by the Senate.

The two chambers could not work out differences in their bill before it expired with the end of the last Congress.

But after a campaign season marred by GOP missteps on the sensitive issue of rape and an election won by Democrats in part because of women’s support, Republican leaders are now eager to find a resolution on the issue.

When the Senate took up a bill similar to one that passed last year with 15 Republican Senate votes, its GOP support grew to 23 senators. A bloc of House Republicans then began urging their leaders to allow the bipartisan version to receive a vote.

“Elections have consequences,” said Terri O’Neal, president of the National Organization for Women, which is part of a broad coalition pushing the Senate version, explaining the shift.

“House Republicans look increasingly out of touch with the American public if they’re the place where these bipartisan bills come to die. I think wiser heads among their leadership recognize that,” said Rep. Chris Van Hollen (D-Md.).

New SDPC mark for cigarettes from 1 March

SINGAPORE: From 1 March, cigarettes sold in Singapore which do not bear the new Singapore Duty-Paid Cigarette (SDPC) mark will be deemed duty-unpaid and illegal.

The new SDPC mark features a series of vertical bars around the cigarette stick.

The Singapore Customs said this allows enforcement officers and the public to easily differentiate duty-paid cigarettes from duty-unpaid or contraband cigarettes.

This measure will also enhance the effectiveness of the anti-contraband cigarette operations that Singapore Customs conducts across the island to curb the selling, buying and possession of contraband cigarettes.

To give manufacturers and retailers sufficient time to phase in the new SDPC mark, cigarettes bearing the new SDPC mark were allowed to be sold from 1 December 2012.

Travellers who bring in cigarettes from overseas for their own consumption are required to declare them at the Customs Red Channel for payment of duty and Goods and Services Tax (GST).

And they are advised to keep the receipt issued by Singapore Customs as proof of payment of duty and GST.

Those who buy, sell, deliver, store, keep, possess or deal with duty-unpaid goods face stiff penalties.

They could be fined up to 40 times the amount of duty evaded and jailed for up to six years.

Members of the public with information on smuggling activities or evasion of Customs duty or GST should contact Singapore Customs on its hotline 1800-2330000 or email customs_intelligence@customs.gov.sg.

Breast cancer on the rise in younger women

NEW DELHI: A study has found that the incidence of advanced breast cancer among American women between 25-39 has steadily increased since the mid-1970s. The findings, published in the Journal of American Medical Association, are devastating because breast cancer patients under 40 years are more likely to have an aggressive form of the disease and face lower survival rates. However, doctors here say developing countries like India have more to worry in comparison.

Additional professor in the department of surgical oncology, AIIMS, Dr S V S Deo says, "Breast cancer cases in India have increased by 10-15% in the last decade. These numbers are likely to rise further - 60-70% of the cases would be in developing countries like India in the future." The number of younger patients in the US has increased at just 2% a year in the last three decades, comprising 1.8% of the total breast cancer cases. In comparison, different studies peg the number of young patients in India between 10-16%.

In recent years, breast cancer has emerged as the most common form of cancer among urban Indian women. Dr Geeta K, senior consultant in surgical oncology at Max Cancer Centre, Delhi, adds, "Of the 25-30 new breast cancer cases that we get in a month, five-six are in the under-35 age group. Some are in their 20s."

Just 10% of these cases are said to be of genetic causes - lifestyle is said to be the major culprit in the rest. Dr Anil Dhar, director, medical oncology, Fortis Memorial Research Institute, Gurgaon, says, "There is no data but personally I feel that exposure to chemicals (in food and the environment) is an important factor in causing breast cancer."

However, doctors say there's no need to panic as survival rates are improving with timely treatment. "Breast cancer is 90% curable in stage 1, and 80% in stage 2. What's required is greater awareness and early treatment. The problem is a majority of the patients here come to us in stage 2 or 3. Even educated women tend to delay treatment for one-two years after detecting a lump," says Dr Deo.
