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.

"Don't Stop Believin'" tops 2012 most-watched dramas list

SINGAPORE: Singapore broadcaster MediaCorp on Friday unveiled the list of most-watched television programmes over its main free-to-air channels.

School drama "Don't Stop Believin'", which features stars like Felicia Chin, Romeo Tan, Elvin Ng and Ian Fang, topped the list of popular Mandarin dramas on Channel 8, with an average viewership of 918,000.

Heartland drama "It Takes Two" trailed close behind, drawing 912,000 viewers each night, with the blockbuster period drama "Joys of Life" rounding out the top three, bringing in 875,000 viewers each episode.

Despite strong competition from imported dramas, locally-produced "Show Hand" emerged tops on Channel U, with 361,000 viewers tuning in for the moving drama series each night.

"Show Hand" beat out Korean drama "He's Beautiful" and Taiwan drama "Material Queen" which both drew 342,000 viewers each episode, and took the second as well as third spot respectively.

Light-hearted Singapore school drama "Jump!" managed to take the fourth spot, with an average viewership of 337,000.

"Crimewatch 2012" was tops on Channel 5, heading the list of most popular English drama and variety series with an average viewership of 382,000 , followed by "Sasuke Singapore", "Point of Entry 2" and its sequel "Point of Entry 3".

Other notable shows include "Food Source", which was named the most popular Mandarin variety show, attracting some 831,000 viewers per episode, as well as "Star Awards 2012 - Show 2", which drew over 1.5 million viewers.

This makes "Star Awards 2012 – Show 2" the most-watched television programme of last year, beating even the televised broadcast of the National Day Parade 2012.

In addition to the viewership figures of its most popular shows, MediaCorp also revealed in the same report that the average viewership of Channel 8, Channel U and Channel 5 has increased in 2012, as had the number of people who watched its programmes online, via xinmsn.com's Catch-up TV service.

Hyderabad blasts: NIA interrogates Indian Mujahideen operatives

HYDERABAD: Two suspected Indian Mujahideen operatives are being questioned by the NIA today in connection with the February 21 twin blasts here that left 16 people dead.

A court in Delhi had yesterday granted the NIA five-day custody of Syed Maqbool and Imran Khan for their interrogation following which the two were brought here by the agency.

The agency had told the court that it would take both of them to Hyderabad and question them for more clues about the blasts, as the ongoing probe points that Indian Mujahideen (IM) module was behind it.

The National Investigation Agency (NIA) had alleged that Maqbool and Khan had in July last year recced Hyderabad's Dilsukhnagar area where the blasts occurred claiming 16 lives and leaving 119 injured.

Maqbool and Khan are presently lodged in Tihar Jail following their arrest by Delhi Police in connection with the August 2012 Pune blast case.

"The duo are in NIA custody and are being questioned here," sources said without elaborating much.

According to the NIA, the blasts took place on the alleged instructions of IM's Pakistan-based founder Riyaz Bhatkal and the duo's interrogation will help in unearthing the exact plan envisaged by him.

The blasts in Hyderabad were triggered by powerful IEDs planted near Konark and Venkatadiri theatres in Dilsukhnagar.

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."

Sequestration: Surrender is in the Air

The budget ax is about to fall, and there's little lawmakers in Washington are doing to stop it.

Despite a parade of dire warnings from the White House, an $85 billion package of deep automatic spending cuts appears poised to take effect at the stroke of midnight on Friday.

The cuts – known in Washington-speak as the sequester – will hit every federal budget, from defense to education, and even the president's own staff.

On Capitol Hill, Senate Democrats and Republicans each staged votes Thursday aimed at substituting the indiscriminate across-the-board cuts with more sensible ones. Democrats also called for including new tax revenue in the mix. Both measures failed.

Lleaders on both sides publicly conceded that the effort was largely for show, with little chance the opposing chamber would embrace the other's plan. They will discuss their differences with President Obama at the White House on Friday.

"It isn't a plan at all, it's a gimmick," Senate Minority Leader Mitch McConnell, R-Ky., said today of the Democrats' legislation.

"Republicans call the plan flexibility" in how the cuts are made, said Senate Majority Leader Harry Reid. "Let's call it what it is. It is a punt."

The budget crisis is the product of a longstanding failure of Congress and the White House to compromise on plans for deficit reduction. The sequester itself, enacted in late 2011, was intended to be so unpalatable as to help force a deal.

Sequestration: Democrats, Republicans Play Blame Game Watch Video

Republicans and Democrats, however, remain gridlocked over the issue of taxes.

Obama has mandated that any steps to offset the automatic cuts must include new tax revenue through the elimination of loopholes and deductions. House Speaker John Boehner and the GOP insist the approach should be spending cuts-only, modifying the package to make it more reasonable.

"Do we want to close loopholes? We sure do. But if we are going to do tax reform, it should focus on creating jobs, not funding more government," House Speaker John Boehner said, explaining his opposition to Obama's plan.

Boehner, McConnell, Reid and House Minority Leader Nancy Pelosi will huddle with Obama at the White House on Friday for the first face-to-face meeting of the group this year.

"There are no preconditions to a meeting like this," White House spokesman Jay Carney said today. "The immediate purpose of the meeting is to discuss the imminent sequester deadline and to avert it."

Even if the leaders reach a deal, there's almost no chance a compromise could be enacted before the deadline. Lawmakers are expected to recess later today for a long weekend in their districts.

What will be the short-term impact of the automatic cuts?

Officials say it will be a gradual, "rolling impact" with limited visible impact across the country in the first few weeks that the cuts are allowed to stand.

Over the long term, however, the Congressional Budget Office and independent economic analysts have warned sequester could lead to economic contraction and possibly a recession.

"This is going to be a big hit on the economy," Obama said Wednesday night.

"It means that you have fewer customers with money in their pockets ready to buy your goods and services. It means that the global economy will be weaker," he said. "And the worst part of it is, it's entirely unnecessary."

Both sides say that if the cuts take effect, the next best chance for a resolution could come next month when the parties need to enact a new federal budget. Government funding runs out on March 27, raising the specter of a federal shutdown if they still can't reach a deal.

"As we anticipate an across-the-board budget cuts across our land, we still expect to see your goodness prevail, O God, " Senate Chaplain Barry Black prayed on the Senate floor this morning, "and save us from ourselves."

Retired Taiwan general charged with spying for China: media

TAIPEI: A retired Taiwanese lieutenant general has been charged with spying for China in the latest of a string of espionage cases to shock the island, according to media reports on Thursday.

Chen Chu-fan, a former vice chief at the Military Police Command allegedly collected intelligence on Taiwan's military and political situation and handed his findings to Beijing, according to the country's FTV news channel.

Chen is also alleged to have recruited a retired military intelligence officer to help him gather information for China, the channel said, citing indictment papers.

Prosecutors were not immediately available for comment, while a defence ministry spokesman confirmed that no active serviceman was implicated in the case.

Taiwan has been hit by a string of spying scandals in recent years, reflecting the fact that intelligence gathering has continued despite warming ties with China.

Earlier this month, a former Taiwanese air force lieutenant colonel received 12 life sentences for spying for China for a reported payment of NT$7.8 million (US$269,000).

In 2011, an army general and chief of an intelligence unit was sentenced to life in prison for spying for China in one of the island's worst espionage scandals.

Union Budget 2013: No IT exemption for cash donations to political parties by cos

NEW DELHI: The government on Thursday proposed to take away the income tax benefit on donations made in cash by corporates to political parties from April 2014 onwards.

Under the existing provisions of section 80GGB of the Income Tax, contribution by an Indian company to any political party or an electoral trust in the previous year, is allowed as deduction in computing the total income of the firm.

Currently, a similar deduction is also available to individuals under section 80GGC. There is no specific mode provided for making such contributions in the Act.

"With a view to discourage cash payments by the contributors, it is proposed to amend the provisions... so as to provide that no deduction shall be allowed under section 80GGB and 80GGC in respect of any sum contributed by way of cash," the Budget document presented in Parliament said.

The amendment, government said, will come into effect from April 1, 2014 and will, accordingly, apply in relation to the assessment year 2014-15 and subsequent assessment years.

Why African Rhinos Are Facing a Crisis

The body count for African rhinos killed for their horns is approaching crisis proportions, according to the latest figures released by the International Union for Conservation of Nature (IUCN).

To National Geographic reporter Peter Gwin, the dire numbers—a rhinoceros slain every 11 minutes since the beginning of 2013—don't come as a surprise. "The killing will continue as long as criminal gangs know they can expect high profits for selling horns to Asian buyers," said Gwin, who wrote about the violent and illegal trade in rhino horn in the March 2012 issue of the magazine.

The recent surge in poaching has been fueled by a thriving market in Vietnam and China for rhino horn, used as a traditional medicine believed to cure everything from hangovers to cancer. Since 2011, at least 1,700 rhinos, or 7 percent of the total population, have been killed and their horns hacked off, according to the IUCN. More than two-thirds of the casualties occurred in South Africa, home to 73 percent of the world's wild rhinos. In Africa there are currently 5,055 black rhinos, listed as critically endangered by the IUCN, and 20,405 white rhinos. (From our blog: "South African Rhino Poaching Hits New High.")

Trying to snuff out poaching by itself won't work, said Gwin. The South African government is fighting a losing battle on the ground to gangs using helicopters, dart guns, high-powered weapons—and lots of money. (National Geographic pictures: The bloody poaching battle over rhino horn [contains graphic images].)

"Every year they get tougher on poaching, but rhino killings continue to rise astronomically," said Gwin. "Somehow they have to address the demand side in a meaningful way. This means either shutting down the Asian markets for rhino horn, or controversially, finding a way to sustainably harvest rhino horns, control their legal sale, and meet what appears to be a huge demand. Either will be a formidable endeavor."

Hope and Hurdles

The signing in December of a memorandum of understanding between South Africa and Vietnam to deal with rhino poaching and other conservation issues raises hope for some concrete action. Observers say the next step is for the two governments to follow through with tangible crime-stopping efforts such as intelligence sharing and other collaboration. The highest hurdle to stopping criminal trade, though, is cultural, Gwin believes. "In Vietnam and China, a lot of people simply believe that as a traditional cure, rhino horn works." (Related: "Blood Ivory.")

The recent climb in rhino deaths threatens what had been a conservation success story. Since 1995, due to better law enforcement, monitoring, and other actions, the overall rhino numbers have steadily risen. The poaching epidemic, the IUCN warns, could dramatically slow and possibly reverse population gains.

The population growth is also being stymied by South Africa's private game farmers, who breed rhinos for sport hunting and tourism and for many years have helped rebuild rhino numbers. Many of them are getting out of the business due to the high costs of security and other risks associated with the poaching invasions.

Those who still have rhinos on their farms will often pay a veterinarian to cut the horns off—under government supervision—to dissuade poachers, but the process costs more than $2,000 and has to be repeated when the horns grow back every two years. Even then the farmers are stuck with horns that are illegal to sell—and which criminals seek to obtain.

Room for Debate

Rhino killings and the trade in their horns will be a major topic at a high-profile conference, the 16th meeting of the Conference of the Parties to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which opens in Bangkok March 3. What won't surprise Gwin is if the issue of sustainably harvesting rhino horns from live animals comes up for discussion.

"It's an idea that seems to be gaining traction among some South African politicians and law enforcement circles," he said, noting that the international conservation community strongly opposes any talk of legalizing the trade of rhino horn, sustainably harvested or not. The bottom line for all parties in the discussion is clear, said Gwin: "The slaughter has to stop if rhinos are to survive."

Benedict XVI Begins Final Day as Pope

Pope Benedict XVI, the first pontiff to resign in 600 years, will step down today to lead a secluded life of prayer, far from the grueling demands of the papacy and the scandals that have recently plagued the church.

Benedict, 85, will spend a quiet final day as pope bidding farewell to his colleagues that have gathered in Vatican City to see him depart. His first order of business this morning is a meeting with the College of Cardinals in the Clementine Hall, a room in the Apostolic Palace, where Angelo Sodano, the dean of the College of Cardinals, is set to speak, but not Benedict.

Pope Benedict XVI Delivers Farewell Address

Despite the historical nature of Benedict's resignation, not all cardinals are expected to attend the event. With their first working meeting not until Monday, only around 100 cardinals are set to be in Vatican City Thursday, the Vatican press office said. Those who are there for Benedict's departure will be greeted by seniority.

In the evening, at 5:00 p.m. local time, Benedict will leave the Vatican palace for the last time to head to Castel Gandolfo, the papal summer residence outside of Rome. Before his departure the German-born theologian will say some goodbyes in the Courtyard of San Damaso, inside the Vatican, first to his Secretary of State Cardinal Tarcisio Bertone and then to the Swiss Guards who have protected him as pontiff.

From there it is a short drive to a heliport for the 15-minute flight via helicopter to Castel Gandolfo, just south of the city. Benedict will not be alone on his journey, accompanied by members of the Pontifical Household such as two private secretaries, the head of protocol, his personal physician and his butler.

Once Benedict lands in the gardens at Castel Gandolfo, a group of dignitaries, such as the governor of the Vatican City state Giovanni Bertello, two bishops, the director of the pontifical villas, and the mayor and parish priest. Off the helicopter and into a car, Benedict will head to the palace that he will call home for the coming months. From a window of the palace, Benedict will make one final wave to the crowd at the papal retreat.

It is there, at 8:00 p.m., that Benedict's resignation will take effect once and for all. Once the gates to the residence close, the Swiss Guards will leave Benedict's side for the last time, their time protecting the pontiff completed.

Pope Benedict's Last Sunday Prayer Service

For some American Catholics in Rome for the historic occasion, Benedict's departure is bittersweet. Christopher Kerzich, a Chicago resident studying at the Pontifical North American College of Rome, said Wednesday he is sad to see Benedict leave, but excited to see what comes next.

"Many Catholics have come to love this pontiff, this very humble man," Kerzich said. "He is a man who's really fought this and prayed this through and has peace in his heart. I take comfort in that and I think a lot of Catholics should take comfort in that."

In his final address to the faithful as leader of the Roman Catholic Church, Benedict on Wednesday said his decision to resign was "the fruit of a serene trust in God's will and a deep love of Christ's Church." Before a crowd of hundreds of thousands of people in St. Peter's Square, Benedict said he was "deeply grateful for the understanding, support, and prayers of so many of you, not only here in Rome, but also throughout the world."

The date of the conclave to determine Benedict's successor has yet to be determined. In one of his last moves as pope, Benedict issued a decree permitting the cardinals to convene the conclave before the March 15 date that would have been required under the old rules.

Benedict is eventually planning to move to a monastery inside Vatican City once work there is finished, but until then he will call home the palace at Castel Gandolfo. He will be known as "pope emeritus" and don brown shoes given to him on his trip to Mexico, rather than the red ones he wore as pontiff.
