Treasury: No $1 trillion coin

A Treasury Department spokesman announced today that the department will not mint a platinum coin to sidestep raising the federal government's borrowing limit, telling the Washington Post that "neither the Treasury Department nor the Federal Reserve believes that the law can or should be used to facilitate the production of platinum coins for the purpose of avoiding an increase in the debt limit."

The idea, which had gained traction among some congressional Democrats and political analysts as a way of defanging the debt ceiling as a bargaining chip, was that the Treasury Department could simply mint a platinum coin, declare the value at $1 trillion, and deposit it into the Federal Reserve to allow continued spending in the absence of a vote to raise the debt ceiling.

With the idea now buried by Treasury, the stage is set for a full-on fight about the debt ceiling. President Obama and congressional Democrats have signaled that they simply will not negotiate on a vote to raise the borrowing limit, saying that it is Congress's duty to pay bills it has already accrued.

But congressional Republicans have given every indication that they plan to use the debt limit as a bargaining chip to extract deep spending cuts from reluctant Democrats.

Poisoned Lottery Winner's Kin Were Suspicious

Urooj Khan had just brought home his $425,000 lottery check when he unexpectedly died the following day. Now, certain members of Khan's family are speaking publicly about the mystery -- and his nephew told ABC News they knew something was not right.

"He was a healthy guy, you know?" said the nephew, Minhaj Khan. "He worked so hard. He was always going about his business and, the thing is: After he won the lottery and the next day later he passes away -- it's awkward. It raises some eyebrows."

The medical examiner initially ruled Urooj Khan, 46, an immigrant from India who owned dry-cleaning businesses in Chicago, died July 20, 2012, of natural causes. But after a family member demanded more tests, authorities in November found a lethal amount of cyanide in his blood, turning the case into a homicide investigation.

"When we found out there was cyanide in his blood after the extensive toxicology reports, we had to believe that ... somebody had to kill him," Minhaj Khan said. "It had to happen, because where can you get cyanide?"

Authorities could be one step closer to learning what happened to Urooj Khan. A judge Friday approved an order to exhume his body at Rosehill Cemetery in Chicago as early as Thursday to perform further tests.

Moments after the court hearing, Urooj Khan's sister, Meraj Khan, remembered her brother as the kind of person who would've shared his jackpot with anyone. Speaking at the Cook County Courthouse, she hoped the exhumation would help the investigation.

"It's very hard because I wanted my brother to rest in peace, but then we have to have justice served," she said, according to ABC News station WLS in Chicago. "So if that's what it takes for him to bring justice and peace, then that's what needs to be done."

Khan reportedly did not have a will. With the investigation moving forward, his family is waging a legal fight against his widow, Shabana Ansari, 32, over more than $1 million, including Urooj Khan's lottery winnings, as well as his business and real estate holdings.

Khan's brother filed a petition Wednesday to a judge asking Citibank to release information about Khan's assets to "ultimately ensure" that [Khan's] minor daughter from a prior marriage "receives her proper share."

Ansari may have tried to cash the jackpot check after Khan's death, according to court documents, which also showed Urooj Khan's family is questioning if the couple was ever even legally married.

Ansari, Urooj Khan's second wife, who still works at the couple's dry cleaning business, has insisted they were married legally.

She has told reporters the night before her husband died, she cooked a traditional Indian meal for him and their family, including Khan's daughter and Ansari's father. Not feeling well, Khan retired early, Ansari told the Chicago Sun-Times, falling asleep in a chair, waking up in agony, then collapsing in the middle of the night. She said she called 911.

"It has been an incredibly hard time," she told ABC News earlier this week. "We went from being the happiest the day we got the check. It was the best sleep I've had. And then the next day, everything was gone.

"I am cooperating with the investigation," Ansari told ABC News. "I want the truth to come out."

Ansari has not been named a suspect, but her attorney, Steven Kozicki, said investigators did question her for more than four hours.

US mulls aid to French in Mali, including drones

WASHINGTON: The US military is weighing support for French forces in Mali including surveillance drones, a US official said Friday, as Washington backed moves to deny safe haven to extremists in the country.

US commanders were looking at providing intelligence and aerial refueling tankers among a range of options, such as logistical backup and boosting intelligence sharing, which would involve surveillance drones, the official, who spoke on condition of anonymity, told AFP.

Backed by French air power, Mali on Friday unleashed an offensive against Islamist rebels who have seized control of the north of the West African country and are now threatening to push south.

Senior US officials held talks with their counterparts in the French capital and other allies on drawing up an action plan, the official said.

President Francois Hollande confirmed in Paris that French forces were supporting an attack aimed at repelling the Al-Qaeda-linked radicals who have triggered international alarm with moves towards the capital Bamako.

The United States said Friday it shared France's goal of denying the extremists safe haven in Mali.

"We are monitoring the situation closely," National Security Council spokesman Tommy Vietor told AFP.

"We have noted that the government of Mali has asked for support, and we share the French goal of denying terrorists a safe haven in the region."

Hollande gave no indication of the scale of French involvement, but said it would last "for as long as is necessary."

The American military has a network of air bases in Italy, Spain and elsewhere in the region that could provide refueling tankers and other assistance to the French.

Former colonial power France has warned that the Islamist rebels were seeking to transform the vast nation into a "terrorist state."

State Department spokesman Victoria Nuland meanwhile said Washington was "consulting very closely" with the French government on the fighting.

"Obviously we remain deeply concerned by the recent events in Mali. We echo the international community's condemnation of these recent aggressive acts."

Earlier Friday, French Defense Minister Jean-Yves Le Drian briefed his US counterpart Leon Panetta about the situation.

Why death comes sooner in America

A report finds that Americans have "shorter lives and poorer health," coming in last in key areas behind 16 other rich nations

STORY HIGHLIGHTS

• Aaron Carroll: New study shows U.S. health and lifespan worst of 17 rich countries


• He says it's because of personal choices, systemic woes. Poverty high, health care uneven


• He says this particularly affects youth, plagued by sickness, violence, high mortality


• Carroll: Don't make it political. The richest country in the world must improve public health

Editor's note: Dr. Aaron E. Carroll is an associate professor of pediatrics at the Indiana University School of Medicine and the director of the university's Center for Health Policy and Professionalism Research. He blogs about health policy at The Incidental Economist and tweets at @aaronecarroll.

(CNN) -- A just-released report from the Institute of Medicine and National Research Council is making news by clearly illustrating that Americans have "shorter lives and poorer health." This is somewhat shocking, given how much we spend on health care each year — more than any of the 16 other rich countries surveyed in the study. What's even more upsetting is that this report focused quite heavily on people who are young. In the United States, even that group fared poorly.

Aaron Carroll

Why is this?

Some of the reasons involve choices make at a personal level. We eat too much, abuse drugs too often, wear seat belts too rarely and commit violence against each other to often.

Systemic issues are also to blame. We have higher levels of poverty than comparable countries, and our safety net programs are less capable of catching people when they fall. And too many also have too much trouble accessing the health care system, resulting in inefficient, ineffective and often absent care.

It's far too easy to let these dreadful statistics become obscured in a politically charged argument. Let's avoid that. This report is so stark that it's going to take a concerted effort on the part of the government, the media, the health care system and everyday citizens to turn things around. Our personal choices are bad. Our safety nets are bad. Our health care system is bad. It's all bad. How bad?

When compared with peer countries, the United States was the absolute worst with respect to still births, infant mortality and low birth weight. Some have tried to blame this on "coding" differences. In other words, they will claim that other countries will refuse to define a premature birth as we do, resulting in artificially high numbers in the United States. But when this report recalculated the rates to exclude such births equally in all countries, we still ranked last.

Things don't get better after birth. The chance that a child in the United States will die before age 5 is higher than in any of the other 16 peer countries. Injuries are the most common cause of death, but the United States also has the highest rate of deaths caused by negligence or abuse.

And violence is decidedly an American problem. Homicide is the third most common cause of death in children age 1-4.

From age 5-19, the trend continues. Kids this age in the United States have the worst health ranking of the 17 studied countries. More than one-third of U.S. children age 5-17 are obese or overweight, the highest of any peer country. The adolescent pregnancy rate in the United States is about 3.5 times the average of others. Additionally, the rates of sexually transmitted infections, including syphilis, gonorrhea and chlamydia are the worst compared to peer countries.

Nor are these children exempt from death. Injury deaths are more common in 15- to 19-year-olds in the United States than in any other studied country. Homicide claims the second highest number of lives in 15- to -24-year-olds, and 4 in 5 of those deaths involve guns. Males between the ages of 15 and 19 are five times as likely to die from violence in the United States than in other countries.

Even as young adults, ages 25-34, mortality remains consistently upsetting and preventable. Unintentional injuries remain the No. 1 cause of death. The risk of dying by violence remains seven times higher for males in the United States ages 20-24 than in other countries.

We have to work together to make these numbers better. Some of them can be improved with public health measures. We need to help Americans be less obese, to have fewer accidents and to commit less violence. There are lots of local studies and initiatives that propose ways to fix these things, but our public health system is woefully underfunded, and translating any promising findings to meaningful societal change poses a huge challenge.

We also need to improve our safety nets to help children at the lowest end of the socioeconomic ladder do better, even before they are born. Pregnant women, babies and children suffer from hunger and malnutrition far too often in the richest country in the world. Yet we still debate the merits of the federally funded WIC (Womens, Infants and Children) program, school lunches and food assistance to needy families.

Finally, we need to find a way to improve access to the health care system. The Medicaid program covers one in every three births and one in every three children in the United States, and it's still not enough. As some states balk at expanding Medicaid to cover many of the poorest uninsured, some are still talking about reducing funding to the already stretched program. There's no question that we have the capability, the knowledge and the resources to care for people. It's just a matter of doing it better.

There will be some who deny these results. Others will try to use them for political gain. That would be a mistake. We have to accept these findings and begin to work holistically to improve them. Being last just isn't the American way.

Pa. VA hospital knew of bacteria problem before death

(CBS News) There's been an outbreak other than the flu at the VA Hospital in Pittsburgh. It raises the question: What do patients have the right to know?

The bacterium that causes the respiratory illness known as Legionnaires' disease was found in the hospital's water system. The hospital and government officials knew about the outbreak but not the patients who were admitted there.

In November, 87-year-old William Nicklas, a Navy veteran, felt nauseated from medication. He went to the Pittsburgh VA hospital. His sons, Bob and Dave Nicklas, weren't particularly concerned.

"He had full trust in the VA," Dave said. "He was loyal to the military, loyal to the treatment he would receive there.It should be the best care in the world."

But in the hospital, he picked up an infection.

"The doctors wanted to meet with us Wednesday night. The family got together, and that's when she told us it was the Legionella bacteria that was the infection," Bob said.

William fought for his life for three days. The day after Thanks giving he was dead. His family thought they would be bringing him home.

What the family didn't know when William checked in was that the Pittsburgh VA had been battling an outbreak of Legionnaires' disease. There were at least four infections before William, and the outbreak had been reported in the hospital's water nearly a year before his death.

The manufacturer of the hospital's Legionella prevention equipment, Liquitech, claims that in December 2011 the Pittsburgh VA told them it had a Legionella problem. In emails, Liquitech wrote the had been made aware of the bacteria and an investigation showed the hospital systems were not being properly maintained.

"If they knew that there was an outbreak at that hospital then you've got two other, you know, world renowned hospitals located directly across the street from the Veterans Hospital," Dave said. "They could have easily transferred those patients so they weren't exposed."

The hospital did report the problem to the county health department and the federal Centers for Disease Control, but it wasn't until two weeks after William was admitted that it went public. It acknowledged that patients had contracted Legionnaire's disease in the hospital. Two weeks later, the hospital announced 24 more were treated there, but the hospital said the origin of 16 of those infections was unknown.

"The facility has worked... to formulate a plan to suppress the Legionella. Testing results indicate remediation... has been successful," Pittsburgh VA said in a statement, declining an interview.

A federal investigation has begun into whether the hospital was prudent in protecting its patients. The hospital said it is under no legal requirement to report Legionnaires' disease cases or outbreaks to the public or its patients. The Nicklas family plans to sue.

Obama Promises Faster Transition in Afghanistan

President Obama and Afghan President Hamid Karzai said today that most U.S. combat operations in Afghanistan would end this spring, signaling a quickening troop drawdown that will bring the decade-long war to a close at the end of 2014.

"Our troops will continue to fight alongside Afghans when needed, but let me say it as plainly as I can: Starting this spring, our troops will have a different mission -- training, advising, assisting Afghan forces," Obama announced at an East Room news conference in Washington.

"It will be a historic moment and another step toward full Afghan sovereignty, something I know that President Karzai cares deeply about, as do the Afghan people," he said.

Administration officials said Afghan forces were "exceeding initial expectations" in their capabilities. Afghan security forces are expected to lead 90 percent of security operations across the country in February.

"By the end of next year -- 2014 -- the transition will be complete," Obama said. "Afghans will have full responsibility for their security, and this war will come to a responsible end."

The rosy assessments belied the serious political, economic and security challenges that remain.

Left unanswered by Obama and Karzai: How many U.S. troops might stay after 2014; what their mission would be and whether they could be effective; and whether the forces would have immunity from prosecution in Afghan courts.

Obama said he was still reviewing recommendations from the Pentagon and will make an announcement in the coming weeks after penning an anticipated bilateral security agreement with Afghanistan. Karzai said the exact number would be up to the United States to decide.

Both leaders confirmed in a statement that the United States "does not seek permanent bases in Afghanistan."

They also agreed today to turn over battlefield combatants held by the U.S. military in Afghanistan to Afghan government control, which has been long-sought by Karzai.

Roughly 66,000 U.S. troops are serving in Afghanistan. The military has proposed keeping several thousand troops in the country after 2014 as advisers, trainers and logistical support for Afghan forces; the White House has said it remains open to pulling out all troops entirely.

Obama's visit with Karzai was the first face-to-face encounter since the November election and since last year's dramatic increase in so-called green-on-blue attacks, when U.S. and NATO soldiers have been killed by the Afghans they are training or working alongside.

There were 45 insider attacks in 2012 that resulted in 62 deaths among coalition forces, including 35 Americans. There has been one attack already in the first 11 days of 2013.

The White House summit included a private Oval Office meeting between Obama, Karzai and Vice President Joe Biden. The trio also attended a private lunch in the Old Family Dining Room.

Karzai Thursday attended meetings with Defense Secretary Leon Panetta and top military brass at the Pentagon, where he was afforded all the pomp and circumstance accorded a head of state: a 21-gun salute, and marching bands and honor guards from the Army, Navy, Air Force, Marines and Coast Guard.

Karzai's relationship with the United States has at times been a rocky one as he has sometimes made critical statements about the allied troop presence in his country. U.S. officials believe he has made those comments out of political expediency to improve his standing with Afghans and show his independence.

Muscle mimic pulls electricity from wet surface

Electricity has been squeezed from a damp surface for the first time, thanks to a polymer film that curls up and moves – a bit like an artificial muscle – when exposed to moisture. The film could be used to run small, wearable devices on nothing but sweat, or in remote locations where conventional electricity sources aren't available.

When a dry polymer absorbs water, its molecular structure changes. This can, in principle, be converted into larger-scale movement, and in turn electricity. But previous attempts at creating a material powered by a moisture gradient – the difference in chemical potential energy between a wet region and a dry region - failed to produce a useful level of force.

These unsuccessful tries used a polymer called polypyrrole. Now Robert Langer and colleagues at the Massachusetts Institute of Technology have turned to the material again, embedding chains of it within another material, polyol-borate. This more complex arrangement mimics structures found in muscles as well as in plant tissues that bend in response to changes in humidity.

Flipping film

The result looks like an ordinary piece of thin black plastic, but when placed on a wet surface, something extraordinary happens. As the material absorbs water, its end curls away from the surface and the film becomes unstable, so it flips over. The ends have now dried out, so they are ready to absorb more water, and the whole process repeats itself. This continuous flipping motion lets the film travel across a suitably moist surface unaided.

Langer found that a 0.03-millimetre-thick strip, weighing roughly 25 milligrams, could curl up and lift a load 380 times its mass to a height of 2 millimetres. It was also able to move sideways when carrying a load about 10 times its mass.

To extract energy from this effect, Langer's team added a layer of piezoelectric material – one which produces electricity when squeezed. When this enhanced film, weighing about 100 milligrams, flipped over, it generated an output of 5.6 nanowatts – enough to power a microchip in sleep mode.

Electricity from sweat

Though the output is small, it is proof that electricity can be extracted from a water gradient. "To the extent of our knowledge, we are the first to utilise a water gradient, without a pressure gradient, to generate electricity," says Langer.

Large-scale energy harvesting is unlikely as the size of the device needed would be impractical, but it could be used to power small devices such as environmental monitoring systems in remote locations. "It will be interesting for applications where the amount of energy needed may be low but where access to energy may be difficult," says Peter Fratzl at the Max-Planck Institute of Colloids and Interfaces in Potsdam, Germany, who was not involved in the work.

Another application, Langer suggests, would be to place the film inside the clothing of joggers or athletes. The evaporation of sweat could generate enough electricity to power sensors monitoring blood pressure and heart rate.

Captain blames faulty brakes, motor for NY ferry accident

NEW YORK: The captain of a packed ferry that crashed into a New York City pier injuring 74 people blamed malfunctioning brakes and a faulty motor for the accident, US investigators said Thursday.

"As the boat was coming in, the captain found that the reverse thrust was not operating as anticipated," said Robert Sumwalt of the National Transportation Safety Board, which is investigating the accident.

The captain said there was also a problem with the motor on the vessel, telling investigators that at some point "both diesel engines shut off," while he steered it toward the pier, Sumwalt told reporters.

There were 326 passengers and five crew on board the ferry at the time of Wednesday's mishap.

The accident took place during the morning rush hour at Pier 11 in lower Manhattan's East River, not far from Wall Street. The ferry was arriving from New Jersey.

Sumwalt said the captain, who is 36 years old, has 12 years of experience as a ferryboat captain and tested negative for alchohol use, as did the entire crew. Results of drug testing have yet to be completed, he said.

Some witnesses reported that the ferry, the Seastreak Wall Street, was going too quickly as it approached the pier.

Weather conditions were good at the time of the accident, with hardly any wind and good visibility.

Dozens of ferries bring thousands of commuters from New Jersey or Brooklyn to Manhattan every day, but accidents are rare.

The most serious mishap, in October 2003, killed 11 people and injured 70 others when a Staten Island ferry slammed into a pier at full speed.

Beheading exposes exploitation

(File photo) Sri Lankan women protest outside the Saudi Arabia embassy in Colombo on November 9, 2010.

STORY HIGHLIGHTS

• Saudi authorities beheaded Rizana Nafeek, a Sri Lankan woman


• She was convicted of killing a baby of the family employing her as a housemaid


• This was despite Nafeek's claims that the baby died in a choking accident


• Becker says her fate "should spotlight the precarious existence of domestic workers"

Jo Becker is the Children's Rights Advocacy Director for Human Rights Watch and author of 'Campaigning for Justice: Human Rights Advocacy in Practice.' Follow Jo Becker on Twitter.

(CNN) -- Rizana Nafeek was a child herself -- 17 years old according to her birth certificate -- when a four-month-old baby died in her care in Saudi Arabia. She had migrated from Sri Lanka only weeks earlier to be a domestic worker for a Saudi family.

Although Rizana said the baby died in a choking accident, Saudi courts convicted her of murder and sentenced her to death. On Wednesday, the Saudi government carried out the sentence in a gruesome fashion, by beheading Rizana.

Read more: Outrage over beheading of Sri Lankan woman by Saudi Arabia

Rizana's case was rife with problems from the beginning. A recruitment agency in Sri Lanka knew she was legally too young to migrate, but she had falsified papers to say she was 23. After the baby died, Rizana gave a confession that she said was made under duress -- she later retracted it. She had no lawyer to defend her until after she was sentenced to death and no competent interpreter during her trial. Her sentence violated international law, which prohibits the death penalty for crimes committed before age 18.

Rizana's fate should arouse international outrage. But it should also spotlight the precarious existence of other domestic workers. At least 1.5 million work in Saudi Arabia alone and more than 50 million -- mainly women and girls -- are employed worldwide according to the International Labour Organization (ILO).

Again according to the ILO, the number of domestic workers worldwide has grown by more than 50% since the mid-1990s. Many, like Rizana, seek employment in foreign countries where they may be unfamiliar with the language and legal system, and have few rights.

When Rizana traveled to Saudi Arabia, for example, she may not have known that many Saudi employers confiscate domestic workers' passports and confine them inside their home, cutting them off from the outside world and sources of help.

It is unlikely that anyone ever told her about Saudi Arabia's flawed criminal justice system, or that while many domestic workers find kind employers who treat them well, others are forced to work for months or even years without pay, and subjected to physical or sexual abuse.

Conditions for migrant domestic workers in Saudi Arabia are among some of the worst, but domestic workers in other countries rarely enjoy the same rights as other workers. In a new report this week, the International Labour Organization says that nearly 30% of the world's domestic workers are completely excluded from national labor laws. They typically earn only 40% of the average wage of other workers. Forty-five percent aren't even entitled by law to a weekly day off.

Last year, I interviewed young girls in Morocco who worked 12 hours a day, 7 days a week for a fraction of the minimum wage. One girl began working at age 12 and told me: "I don't mind working, but to be beaten and not to have enough food, this is the hardest part."

Many governments have finally begun to recognize the risks and exploitation domestic workers face. During 2012, dozens of countries took action to strengthen protections for domestic workers. Thailand, and Singapore approved measures to give domestic workers a weekly day off, while Venezuela and the Philippines adopted broad laws for domestic workers ensuring a minimum wage, paid holidays, and limits to their working hours. Brazil is amending its constitution to state that domestic workers have all the same rights as other workers. Bahrain codified access to mediation of labor disputes.

Perhaps most significantly, eight countries acted in 2012 to ratify -- and therefore be legally bound by -- the Domestic Workers Convention, with more poised to follow suit this year. The convention is a groundbreaking treaty adopted in 2011 to guarantee domestic workers the same protections available to other workers, including weekly days off, effective complaints procedures and protection from violence.

The Convention also has specific protections for domestic workers under the age of 18 and provisions for regulating and monitoring recruitment agencies. All governments should ratify the convention.

Many reforms are needed to prevent another tragic case like that of Rizana Nafeek. The obvious one is for Saudi Arabia to stop its use of the death penalty and end its outlier status as one of only three countries worldwide to execute people for crimes committed while a child.

Labor reforms are also critically important. They may have prevented the recruitment of a 17 year old for migration abroad in the first place. And they can protect millions of other domestic workers who labor with precariously few guarantees for their safety and rights.
