Herbal Viagra actually contains the real thing

IF IT looks too good to be true, it probably is. Several "herbal remedies" for erectile dysfunction sold online actually contain the active ingredient from Viagra.

Michael Lamb at Arcadia University in Glenside, Pennsylvania, and colleagues purchased 10 popular "natural" uplifting remedies on the internet and tested them for the presence of sildenafil, the active ingredient in Viagra. They found the compound, or a similar synthetic drug, in seven of the 10 products – cause for concern because it can be dangerous for people with some medical conditions.

Lamb's work was presented last week at the American Academy of Forensic Sciences meeting in Washington DC.

Third Malaysian policeman killed in Borneo: report

LAHAD DATU, Malaysia - A Malaysian policeman was killed by "militants" in a region where Filipino followers of a self-claimed sultan are holed up in a deadly standoff with security forces, state media reported Sunday.

The police officer was killed when he was fired upon on Saturday in the Malaysian town of Semporna, 300 kilometres by road from the site of the standoff at Tanduo village on Borneo island where 12 Filipino intruders and two police died in a firefight the day before.

State news agency Bernama also said another officer suffered gunshot wounds.

It quoted police saying the killing was unrelated to the nearly three-week siege involving armed intruders who arrived from the Philippines by boat to press the "sultan's" historical claim to the area.

But the latest shooting raised fears on Malaysian social media sites of a possible spread of violence by suspected sympathisers of the group.

An estimated 100-300 Filipinos have been surrounded in a farming village by a Malaysian police and military cordon since landing by boat from the nearby Philippines to insist the area belongs to their Islamic leader Jamalul Kiram III's.

Kiram, 74, claims to be the heir to the Islamic sultanate of Sulu, which once controlled parts of the southern Philippines and Borneo.

Following Friday's firefight, Malaysian police stepped up threats to clear them out unless they surrendered immediately.

Philippine President Benigno Aquino, who has sharply criticised the intruders, also urged them to surrender unconditionally, but a spokesman for Kiram has said his followers were prepared to die.

The Sulu sultanate's power faded about a century ago but it has continued to receive nominal payments from Malaysia for Sabah under a historical lease arrangement passed down from European colonial powers.

Romney: Sequester not a success for Obama

Mitt Romney may not be running for the White House any more, but he certainly came out swinging against President Obama in his first post-election interview with "Fox News Sunday," accusing the president of poisoning the negotiations over automatic spending cuts by "berating" Republicans.

"No one can think" that the fight over the sequester has "been a success for the president," last year's Republican presidential nominee said. "He didn't think the sequester would happen. It is happening, but to date, what we've seen is the president out campaigning to the American people, doing rallies around the country, flying around the country and berating Republicans. And blaming and pointing."

"Now what does that do?" He asked. "That causes the Republicans to retrench and then put up a wall and fight back. It's a very natural human emotion."

The former Massachusetts governor also criticized the recent release of several hundred illegal immigrants detained by the U.S. Immigration and Customs Enforcement agency. The agency justified the release as a cost-saving measure forced on them by the across-the-board budget cuts, but Romney argued that the president should have prevented it. "I think if there are people who are incarcerated," he said, the president "should make sure that we're able to keep them in jail."

"Look, it's- again, it's politics," he said. "It's, 'OK, how do we do something that will get a headline that will make it look like those terrible Republicans aren't willing to come together?'"

In the interview, which airs Sunday, Romney also addressed the adjustment to life after the campaign trail. "We were on a roller coaster, exciting and thrilling, ups and downs," he said. "But the ride ends, and then you get off."

His wife Ann Romney, who also sat for the interview, agreed that it has been quite a change but added, "The good news is, fortunately, we like each other."

US Seeks to Confirm Report of Terror Leader's Death

American military and intelligence officials said today they are attempting to confirm a report from the Chadian military of the death of al Qaeda leader Mokhtar Belmokhtar, the alleged mastermind of the deadly attack on an Algerian natural gas facility in January.

If the new report is confirmed, Belmokhtar's death would be a significant victory against a growing al Qaeda threat in northern Africa.

Belmokhtar's killing was announced on Chadian national television by armed forces spokesperson Gen. Zacharia Gobongue, who said Chadian troops "operating in northern Mali completely destroyed a terrorist base."

"The [death] toll included several dead terrorists, including their leader, Mokhtar Belmokhtar," he said.

However, an unidentified elected official in Mali told The Associated Press he doubted Belmokhtar had actually been killed and said he suspected the Chadian government of pushing the story to ease the loss of dozens of Chadian troops in operations in northern Africa.

Belmokhtar is known as Mr. Marlboro because of the millions he made smuggling cigarettes across the Sahara, but in the last few months the one-eyed terrorist leader has become one of the most sought after terrorists in the world. The attack on the plant near In Amenas in eastern Algeria left dozens of Westerns and at least three Americans dead.

Belmokhtar had formed his own al Qaeda splinter group and announced he would use his wealth to finance more attacks against American and Western interests in the region and beyond.

The U.S. has badly wanted Belmokhtar stopped and actively helped in the search by French and African military units to find him, as well as another top al Qaeda leader who was reported killed yesterday.

After the Chadian announcement, House Foreign Affairs Committee Chairman Rep. Ed Royce (R-Calif.) said Belmokhtar's death, if confirmed, "would be a hard blow to the collection of jihadists operating across the region that are targeting American diplomats and energy workers."

Steve Wysocki, a plant worker who survived the attack in In Amenas thanked "military forces from around the world," especially the Chadian military, for bringing "this terrorist to an expedient justice."

"My family and I continue to mourn for our friends and colleagues who didn't make it home and pray for their families," Wysocki told ABC News.

The CIA has been after Belmokhtar since the early 1990s, Royce's statement said.

US Defence Secretary Hagel scolds budget cuts

WASHINGTON: Major budget cuts will endanger the US military's ability to conduct its missions, Pentagon chief Chuck Hagel warned.

His comments came hours before President Barack Obama authorized cuts in domestic and defence spending, following the failure of efforts to clinch a deal with Republicans on cutting the deficit.

Hagel, whose budget at the Pentagon is set to be slashed by roughly $46 billion, said earlier: "Let me make it clear that this uncertainty puts at risk our ability to effectively fulfil all of our missions."

In contrast with his predecessor Leon Panetta, who branded the cuts a "doomsday mechanism" and "fiscal castration," Hagel was more measured two days after taking office as defence secretary.

But he made clear his thoughts on the consequences of the so-called "sequester" on the military.

Defence officials say they will be forced to reduce the working week of 800,000 civilian employees, scale back flight hours of warplanes and postpone some equipment maintenance.

The deployment of a second aircraft carrier to the Gulf has also been cancelled.

The US Navy will gradually stand down several hundred planes starting in April, the Air Force will curtail flying hours and the Army will cut back training for all units except those deploying to Afghanistan.

"This will have a major impact on training and readiness," Hagel said. "Later this month, we intend to issue preliminary notifications to thousands of civilian employees who will be furloughed."

Hagel acknowledged that the budget cuts "will cause pain, particularly among our civilian workforce and their families."

"I'm also concerned, as we all are, about the impact on readiness that these cuts will have across our force," he added.

The Pentagon chief expressed "confidence" that the White House and President Barack Obama's Republican foes in Congress would eventually reach agreement.

But other officials laid bare the consequences.

"If you stop training for a while and you're a combat pilot, then you lose your rating and eventually can't fly at all, because we can't allow you to fly if you can't fly safely," said Ash Carter, Hagel's deputy at the Pentagon.

"You can't, you obviously can't fly proficiently, but you can't even fly safely. Then you have to go back to the long building-back process of getting your readiness back."

Obama was bound by law to initiate the automatic, indiscriminate cuts.

The hit to military and domestic spending, known as the sequester, was never supposed to happen, but was rather a device seen as so punishing that rival lawmakers would be forced to find a better compromise to cut the deficit.

But despite a looming reality that the nation would suffer, Democrats and Republicans remained far from compromise and were never close to agreement.

Obama signs order activating 'dumb' spending cuts

STORY HIGHLIGHTS

• NEW: Obama signs order that is required by law


• "We will get through this," President Obama says of the forced spending cuts


• Obama, congressional leaders fail to bridge gaps on cuts, letting them take effect


• Speaker Boehner says the House will take up a government funding measure

Washington (CNN) -- Politics trumped progress on Friday as President Barack Obama and Republican leaders traded blame for $85 billion in forced spending cuts after they failed to come up with a compromise to avert the harshest impacts.

The president signed an order required by law that set in motion the automatic, government-wide cuts.

Obama and congressional leaders from both parties met for about 45 minutes at the White House, but no agreement emerged to avert the cuts that both sides oppose.

After weeks of campaign-style events intended to inspire public outrage over the cuts, Obama sought to temper his description of their impact while making clear he thinks Republican intransigence prevented a deal to avoid the economic harm they'll cause.

"We will get through this," he told reporters. "This is not going to be an apocalypse as some people have said. It's just dumb and it's going to hurt."

Full text of Obama order

Still, a White House budget office report sent to Congress and released with Obama's order said the cuts would be "deeply destructive to national security, domestic investments, and core government functions."

The action was described in the report as "a blunt and indiscriminate instrument" that was "never intended to be implemented and does not represent a responsible way" for the country to realize deficit reduction.

OMB report to Congress

In a sign of the potential impact, the Department of Justice sent furlough notices to employees that warned they may be forced to take days off without pay in coming months.

Similar furloughs, as well as reduced services, were expected at other agencies if the cuts don't get replaced or eliminated. Military leaders have warned of impaired readiness of U.S. forces.

Shame and blame: Why Washington needs couples therapy

However, the full impact of the cuts weren't expected until April at the earliest.

The cuts amount to roughly 9% for a broad range of non-defense programs and 13% for the Pentagon over the rest of the current fiscal year, which ends on September 30.

They were included in a 2011 deal to raise the federal borrowing limit as an unacceptable outcome if Congress failed to agree on a comprehensive deficit reduction plan.

Obama's press conference on spending cuts

However, election-year politics stymied progress on such a deal, leading to the situation Friday in which both sides acknowledged being unable to prevent something neither wanted.

"There are smarter ways to cut spending," said House Speaker John Boehner, R-Ohio, after the meeting with Obama.

Boehner repeated his past assertion that the GOP-led House has offered proposals to replace the forced spending cuts while the Democratic-led Senate has not, as well as his party's opposition to any increased tax revenue to offset the forced spending cuts.

Others who also took part in the White House gathering were Senate Majority Leader Harry Reid, Senate Minority Leader Mitch McConnell and House Minority Leader Nancy Pelosi.

In the White House briefing room, Obama told reporters that Republicans in Congress "allowed these cuts to happen because they refuse to budge on closing a single wasteful (tax) loophole to help reduce the deficit."

"As recently as yesterday, they decided to protect special interest tax breaks for the well off and the well connected and they think that that's apparently more important than protecting our military or middle class families from the pain of these cuts," Obama said.

He was referring to a procedural vote on Thursday in which Senate Republicans blocked a Democratic proposal that called for eliminating some tax loopholes as part of a package with spending cuts.

Boehner and Republicans say the president and Democrats have yet to propose a serious plan to reduce spending, including costly entitlement programs, on a scale necessary to bring chronic federal deficits and debt under control.

Both Obama and Boehner foreshadowed the next major spending showdown - a March 27 deadline for Congress to authorize funding to keep the government running for the rest of the fiscal year.

4 myths about the spending cuts

Boehner told reporters that the House will take up a measure next week to authorize federal funding beyond that deadline.

"The president and leaders agreed legislation should be enacted this month to prevent a government shutdown while we continue to work on a solution to replace the" forced spending cuts, said a statement by Boehner's office.

Although the funding measure is unconnected to the spending cuts, Obama indicated he was open to a broader agreement that would resolve both issues.

"I do know that there are Republicans in Congress who privately, at least, say that they would rather close tax loopholes then let these cuts go through," said Obama in response to questions from reporters.

"... In the coming days and the coming weeks, I'm going to keeping on reaching out to them -- both individually and as groups of senators or members of the House -- and say to them, 'Let's fix this, not just for a month or two, but for years to come,' because the greatest nation on Earth does not conduct its business in month-to-month increments or by careening from crisis to crisis," Obama said.

What does the WH's brief for Supreme Court mean for same-sex marriage?

(CBS News) WASHINGTON - At his news conference Friday, President Obama was asked about his decision to get involved in the battle over same-sex marriage in California's ban on same-sex marriage. Late Thursday, the administration filed a brief with the Supreme Court, saying that California's ban on gays and lesbians marrying violates their constitutional rights.

"If the Supreme Court asks me or my attorney general or solicitor general, 'Do we think that meets constitutional muster?' -- I felt it was important for us to answer that question honestly. And the answer is no," said the president

CBS News chief legal correspondent Jan Crawford spoke with "Evening News" anchor Scott Pelley about the brief and its potential impact. A transcript of the conversation follows.

Obama: If I were on Supreme Court, I'd defend same-sex marriage
Obama administration urges Supreme Court to overturn Calif. same-sex marriage ban
Clint Eastwood signs pro-gay marriage brief

Scott Pelley: Jan, the court will hear arguments later this month that will impact all of this. I wonder what the president's comments today have to do with the case?

Jan Crawford: Well Scott, as the president said today,"I'm not a judge, I'm the president." His views carry no binding authority in the Supreme Court. Just because the administration is making this argument doesn't mean the court has to go along with it. The federal government is not directly involved in this case -- it's a challenge by same-sex couples in California to a California constitutional amendment that bans gay marriage. The administration chose to get involved to make a strong statement on gay rights that are reflected in his comments today. The brief in fact is more important politically and symbolically than legally.

Pelley: The case is centered on California. Could it have wider-ranging implications?

Crawford: Yes, it certainly could . Even though this case comes from California, it could have an enormous impact across the country. California is one of 30 states that has a constitutional amendment banning gay marriage. The decision could affect all of those laws -- that's more than half the states in this country. And if the Supreme Court agrees with the president -- that amendments like California's are unconstitutional -- many or all of those laws banning gay marriage could be in jeopardy.

Sequester Could Cut Blue Angels, Medicare Payments

Mar 1, 2013 2:28pm

(Image Credit: Justin Sullivan/Getty Images)

Starting today, The Note will track how automatic budget cuts associated with the so-called sequester are hurting Americans at home. This story of the effects on one community is part of that series.

If nothing is done to avert “sequester” cuts, air-show fans can wave bye-bye to the Blue Angels.

The Navy’s demonstration air team plans to cancel the 28 performances it has scheduled between April 1 and Sept. 30 if the cuts go into effect as planned at midnight tonight and revenue is not somehow supplemented.

Read more: Sequester to Cut $85 Billion from Federal Agencies

It’s just one of the many sacrifices the Defense Department plans to make if its budget suffers the across-the-board cuts prescribed in the sequestration bill signed into law in August 2011.

Florida State Sen. Don Gaetz, R-Niceville, said the cancelled shows would mean the loss of what he called his constituents’ “civic religion.”

“If someone you don’t know gets furloughed from a job at a military base, that’s something you read about in the newspaper. But if the Blue Angels are grounded, that’s a highly visible symbol of government dysfunction,” Gaetz said today.

A performance in Indiana slated for June has already been cut, thanks to the sequester, but that was the choice of the organizers, not the Navy, according to Blue Angels Public Affairs Officer Lt. Kathryn Kelly.

The next show on the chopping block would be the April 6-7 Airfest performance at MacDill Air Force Base in Tampa, Fla.

Terry Montrose, deputy chief of public affairs for Macdill Air Force Base, said if that performance is cancelled, the whole air show will be shut down, a true disappointment for the Tampa community.

“I’m sure it would be a big blow to [Tampa residents], because it’s one of the largest events in Tampa every year or every other year,” Montrose said.

Read More: What Is Sequestration?

Montrose said the base is “hoping for a Hail Mary” to save the show.

But Kelly of the Blue Angels said the squadron’s fate is not sealed just yet. If Congress passes a full budget, another continuing resolution or an increase to the Navy’s transfer authority, more shows could be restored.

Sen. Gaetz pointed out that losing the Blue Angels wouldn’t be the worst of the sequester’s effects in the Sunshine State.

“As important as they are and as symbolic as they are, [the Blue Angels] aren’t as important as making sure that someone in a nursing home gets care or someone in aerospace gets a paycheck,” he said. “But, obviously, sometimes it’s the symbols that resonate with people and bring the issue home.”

The tourism, higher education, civilian defense contractor and hospital industries in Florida would all take hits as the cuts filter down, according to Chris McCarty, director of the Bureau of Economic and Business Research at the University of Florida in Gainesville.

In 2011, 17.6 percent of Florida’s population was eligible for Medicare, 4.3 points higher than the national average. That means scaling back Medicare payments to hospitals will disproportionately affect the health care industry in that state, according to Gaetz.

“When Medicare catches a cold,” he said,  “Florida hospitals get pneumonia.”

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."

Initiatives outlined to make it easier for public to get legal help

SINGAPORE: The overarching theme of the Subordinate Courts Workplan seminar this year is to make it easier for the public to get legal help and information.

In his first workplan keynote address, Chief Justice Sundaresh Menon outlined a slew of initiatives to resolve informational inadequacy and litigation costs.

These include the Primary Justice Project to have a team of lawyers who will provide basic legal services to the public, coming up with guide books on motor vehicle accident scenarios, and simplifying the process for minor civil cases.

The initiatives point towards one thing - settling disputes out of court so as to save time and costs.

Manning pleads guilty in WikiLeaks case

(CBS News) WASHINGTON - In a surprise Thursday, Army Pfc. Bradley Manning pleaded guilty to ten criminal counts in the biggest leak of classified material in U.S. history. Manning sent files to the website Wikileaks. He still faces trial on more serious charges.

Along with the guilty pleas, Manning gave his first detailed explanation of why he did it.

Reading from a 35-page statement, the Army private said he wanted the world to know the truth about the wars in Iraq and Afghanistan.

Depressed and frustrated by the wars, he used his job as a low-ranking intelligence analyst in Baghdad to download onto a CD hundreds of thousands of classified documents -- pus a few videos, one of which depict a helicopter gunship attack that killed two journalists in Iraq, which he found "troubling" because it showed "delightful bloodlust."

Judge accepts Manning's guilty pleas in WikiLeaks case
Manning's sexual orientation discussed in court

Describing himself as a misfit in the military, Manning told the judge he first contacted The Washington Post but didn't think the reporter took him seriously; then called The New York Times' tip line but never heard back.

He was home on leave during a blizzard, which paralyzed Washington, and left him stranded at his aunt's house when he decided to send the material to WikiLeaks, the website which had a reputation for exposing secrets.

He included a brief note, ending with "Have a good day," and went back to Iraq with "a sense of relief" and "a clear conscience."

Despite pleading guilty to some of the charges, Manning still faces a court martial and possible life sentence for allegedly aiding the enemy.

Prosecution attorneys have said they intend to show that some of the leaked documents were found by Navy SEALs in their raid on Osama bin Laden's hideout. According to a military attorney, the prosecution does not have to prove Manning intended for the documents to end up in enemy hands -- only that he knew it might happen.

Manning testified that no one at WikiLeaks pressured him for more documents and that he knew what he did was wrong.

Obama Admin to Court: End Calif. Gay Marriage Ban

In a historic argument for gay rights, President Barack Obama on Thursday urged the Supreme Court to overturn California's same-sex marriage ban and turn a skeptical eye on similar prohibitions across the country.

The Obama administration's friend-of-the-court brief marked the first time a U.S. president has urged the high court to expand the right of gays and lesbians to wed. The filing unequivocally calls on the justices to strike down California's Proposition 8 ballot measure, although it stops short of the soaring rhetoric on marriage equality Obama expressed in his inaugural address in January.

Justin Sullivan/Getty Images

California is one of eight states that give gay couples all the benefits of marriage through civil unions or domestic partnership but don't allow them to wed. The denial of marriage to same-sex couples, "particularly where California at the same time grants same-sex partners all the substantive rights of marriage, violates equal protection," the administration said.

The administration's position, if adopted by the court, would likely result in gay marriage becoming legal in the seven other states: Delaware, Hawaii, Illinois, Nevada, New Jersey, Oregon and Rhode Island.

In the longer term, the administration urges the justices to subject laws that discriminate on sexual orientation to more rigorous review than usual, a standard that would imperil other state bans on same-sex marriage.

The brief marks the president's most expansive view of gay marriage and signals that he is moving away from his previous assertion that states should determine their own marriage laws. Obama, a former constitutional law professor, signed off on the administration's legal argument last week following lengthy discussions with Attorney General Eric Holder and Solicitor General Donald Verrilli.

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.

Asian markets rise on Wall St rally, ECB comments

HONG KONG: Asian markets rose Thursday after the Dow on Wall Street hit a more than five-year high, while the head of the European Central Bank soothed concerns over the eurozone.

A strong bond sale in Italy also helped the euro despite uncertainty after weekend polls, while the yen resumed its downward trend after Japan's government nominated a fan of aggressive easing as the new central bank governor.

Tokyo climbed 2.04 per cent as the yen sank on confirmation that Japan's government had put forward Haruhiko Kuroda to take over at the Bank of Japan.

Kuroda, the current Asian Development Bank chief, is known as an advocate of a looser monetary policy to overcome slow growth, in line with the views of Prime Minister Shinzo Abe.

The dollar bought 92.44 yen, compared with 92.16 yen in New York late Wednesday.

Hong Kong shares advanced 1.10 per cent, Sydney added 0.71 per cent, Seoul rose 1.02 per cent and Shanghai was up 0.39 per cent.

ECB President Mario Draghi said Wednesday the bank would preserve the integrity of the eurozone, reasserting its commitment to buy up bonds of under-pressure countries.

"We are committed to preserving the integrity of our currency, in the interests of all people of the euro area," he said.

The announcement, which came after US Federal Reserve Chairman Ben Bernanke said its own huge easing would stay in place, came as welcome relief to markets after Italy's poll deadlock raised fears of a return to Europe's debt crisis.

On forex markets the euro rebounded after being hammered in the wake of Sunday's inconclusive poll, which saw voters shun austerity policies and leave the country with a hung parliament.

The euro sat at $1.3150 and 121.56 yen in Tokyo, from $1.3136 and 121.07 yen -- and well up from the levels just above $1.30 and 119 yen seen earlier in the week.

The single currency was also given support from news that Rome had successfully sold 6.5 billion euros of treasury bonds, albeit at a higher price, providing evidence for now that it can borrow cash to pay its own bills.

On Wall Street the Dow ended at its highest level since October 2007 after reports showed US pending home sales rebounded sharply in January to the highest level in almost three years.

In other positive news, durable goods orders in January -- excluding volatile aircraft -- surged 1.9 per cent, with gains particularly strong in capital goods, suggesting business confidence in the economy in upcoming months.

The Dow jumped 1.26 per cent, while the S&P 500 rose 1.27 per cent and the Nasdaq added 1.04 per cent.

Oil prices rose, with New York's main contract, light sweet crude for delivery in April, gaining 34 cents to $93.10 a barrel and Brent North Sea crude for April delivery adding 35 cents to $112.22.

Gold was at $1,597.70 at 0220 GMT compared with $1,608.32 late Wednesday.

Supreme Court divided on Voting Rights Act

(CBS News) WASHINGTON -- The Voting Rights Act has been the law of the land for nearly half a century, helping to ensure that minorities are not denied the right to vote. On Wednesday, Shelby County, Ala., challenged the law at the Supreme Court.

The arguments sharply divided the justices: The court's conservative majority appeared poised to strike down at least part of the act and eliminate the current federal oversight of voting in the South.

At issue is a decades-old provision in the law that requires nine states, mostly in the South, to get approval from the federal government before changing voting laws or procedures.

Justice Antonin Scalia called it a "racial entitlement."

Chief Justice John Roberts asked if the government believed "the citizens in the South are more racist than citizens in the North." Roberts said current data on voter turnout revealed more problems in Massachusetts than in Mississippi.

Congress did not rely on current data when, in 2006, it reauthorized the Voting Rights Act. It continued to rely on rates of minority voter registration and turnout in the elections of 1964, 1968 and 1972.

Alabama attorney Frank Ellis said Congress should look at the modern-day South.

"We ask for some recognition that we and these other converted jurisdictions have made great strides over the last 48 years," Ellis said.

The liberal justices strongly defended the law, saying Congress had thousands of pages of evidence documenting discrimination.

"Discrimination is discrimination, and what Congress said is it continues," Justice Sonia Sotomayor said.

Justice Stephen Breyer said, "The disease is still there ... it's gotten a lot better, a lot better, but it's still there."

That's why civil rights attorney Debo Adegbile said the provision is as necessary today as a generation ago.

"The problems are much more serious, much more repetitive, there is a much greater continuity in certain places than others," Adegbile said.

The liberal justices -- and the Obama administration -- say the court should defer to Congress, which they say is was better situated to make judgments about discrimination in voting. But based on the arguments today, it does appear a majority of the conservative judges are ready to tell Congress it's going to have to make some changes in that law.

Holder Says Sequester Makes America Less Safe

The looming budget sequestration will make Americans less safe, Eric Holder says—and anyone who says otherwise isn't telling the truth.

"This is something that is going to have an impact on the safety of this country," the U.S. attorney general told ABC's Pierre Thomas on Wednesday in a wide-ranging, exclusive interview.

"And anybody that says otherwise is either lying or saying something that runs contrary to the facts," Holder said.

In his interview with ABC News, Holder reiterated warnings that if automatic spending cuts are triggered on Friday, the Justice Department will be handicapped in some of its most vital missions to prevent terrorist attacks and crime.

"The Justice Department is going to lose nine percent of its budget between now and September 30th. We're going to lose $1.6 billion. There are not going to be as many FBI agents, ATF agents, DEA agents, prosecutors who are going to be able to do their jobs," Holder said. "They're going to be furloughed. They're going to spend time out of their offices, not doing their jobs."

Portions of the interview will air Wednesday, February 27 on "ABC World News"

Eric Holder Says Homegrown Terror Threat Equals International: Exclusive Watch Video

Eric Holder Remembers Newtown, His Worst Day on the Job: Exclusive Watch Video

President Obama's Cabinet members have been warning for weeks that budget sequestration, which will begin Friday unless Obama and Republicans reach a deficit-reduction deal to avoid it, will leave their agencies shorthanded and could bring about disastrous consequences. Homeland Security Secretary Janet Napolitano and Transportation Secretary Ray LaHood have both appeared at the White House press briefing room to warn that furloughs for border-patrol agents, TSA agents and air-traffic controllers will mean weakened border and port security, longer waits in airport security lines, and logjammed air travel.

Holder, for his part, warned in a Feb. 1 letter to the Senate Appropriations Committee that cuts to the FBI, the ATF, the U.S. Marshals Service, and U.S. Attorneys would limit the department's capacity to investigate crimes. Cuts at the Bureau of Prisons, Holder wrote, would mean lockdowns and potential violence, with fewer staff members on hand. In a separate letter, FBI Director Robert Mueller warned that counterterrorism operations would be affected, with the possible elimination of some joint terrorism task forces with state and local police. Limited surveillance and slower response times would mean unwatched targets and the possibility that individuals on terrorism watch lists could gain entry to the U.S.

"FBI's ability to proactively penetrate and disrupt terrorist plans and groups prior to an attack would be impacted," Mueller wrote.

To Holder, the problem is simple.

"If you don't have prosecutors and agents doing what we expect them to do, and we won't if this thing actually takes place, we are going to be a nation that is going to be less safe. And that is simple fact," Holder said.

Some Republicans have claimed the Obama administration is exaggerating the sequester's purported consequences as a ploy to campaign for tax hikes. On "Fox News Sunday" this week, Sen. Tom Coburn, R-Okla., posited that federal agencies enjoy enough flexibility to avoid the worst consequences of the cuts.

On Wednesday, Holder acknowledged that the Justice Department will do what it can to avoid compromised security, while maintaining that furloughs can't be avoided.
