U.S. Senate Intelligence Committee drops bin Laden film probe

WASHINGTON (Reuters) - One day after "Zero Dark Thirty" failed to win major awards at the Oscars, a congressional aide said on Monday the Senate Intelligence Committee has closed its inquiry into the filmmakers' contacts with the Central Intelligence Agency.

The intelligence committee gathered more information from the CIA and will not take further action, according to the aide, who requested anonymity.

Sony Pictures Entertainment, which distributed the film in the United States, had no immediate comment. But attacks by Washington politicians may have damaged its prospects at the Academy Awards. "Zero Dark Thirty" was nominated for a best picture award, which it did not win. Also, in what industry watchers considered a snub, director Kathryn Bigelow did not receive a best director nomination.

The Senate committee launched its review of the film, a dramatization of how the U.S. government located and killed Osama bin Laden, after its chairwoman, Senator Dianne Feinstein, expressed outrage over scenes that implied that "enhanced interrogations" of CIA detainees produced an breakthrough that helped lead to the al Qaeda leader.

In December, as "Zero Dark Thirty" was about to premiere nationwide, Feinstein joined fellow Democrat Carl Levin, chairman of the Senate Armed Services Committee, and Republican Senator John McCain in condemning "particularly graphic scenes of CIA officers torturing detainees" in the film.

A source familiar with contacts between the filmmakers and intelligence officials said the CIA did not tell the filmmakers "enhanced interrogations" led to bin Laden. Instead, the agency helped develop characters in the film, said the source.

The political fallout prompted Bigelow to write in an op-ed piece: "Those of us who work in the arts know that depiction is not endorsement. If it was, no artist would be able to paint inhumane practices, no author could write about them, and no filmmaker could delve into the thorny subjects of our time."

The government cooperated as much, if not more, on "Argo," the film about the 1979-81 hostage crisis in Iran that won the best picture Oscar. Actor-director Ben Affleck and his team were allowed to film scenes in the lobby of the CIA building in Langley, Virginia; the "Zero Dark Thirty" crew did no such filming.

(The story corrects paragraph 2 and 3 to fix who committee got intelligence from and that Sony is distributor not producer of film)

Clean Your Washing Machine To Keep Clothes Fresh

Clean Your Washing Machine To Keep Clothes Fresh Washing machines take the dirt and germs out of our clothes, but a lot of that grime just ends up trapped in the machine itself. It's pretty easy to clean your top-loader though with a few basic supplies.

Regina Yunghans at Apartment Therapy wrote a great walkthrough to help you clean and disinfect your machine. Adding vinegar and baking soda to an empty wash cycle will do a fine job of disinfecting the wash tub, but cleaning the fabric softener well or those gross crevices under the lid will require some old fashioned elbow grease and a toothbrush. You don't need to do this after every load, but giving your machine some care every few months will help keep dirt from accumulating inside and transferring to your (supposedly) clean clothes. Be sure to check the source link for the step-by-step guide.

Fingerprint Purchasing Technology Ensures Buyer Has a Pulse

An anonymous reader writes "A small U.S. university has come up with a novel solution to reduce the possibility of using a dead person's hand to get past a fingerprint scanner through the use of hemoglobin detection. The device quickly checks the fingerprint and hemoglobin 'non-intrusively' to verify the identity and whether the individual is alive. This field of research is called Biocryptology and seeks to ensure that biometric security devices can't be easily bypassed."

Scientists develop a whole new way of harvesting energy from the sun

Feb. 24, 2013 ? A new method of harvesting the Sun's energy is emerging, thanks to scientists at UC Santa Barbara's Departments of Chemistry, Chemical Engineering, and Materials. Though still in its infancy, the research promises to convert sunlight into energy using a process based on metals that are more robust than many of the semiconductors used in conventional methods.

The researchers' findings are published in the latest issue of the journal Nature Nanotechnology.

"It is the first radically new and potentially workable alternative to semiconductor-based solar conversion devices to be developed in the past 70 years or so," said Martin Moskovits, professor of chemistry at UCSB.

In conventional photoprocesses, a technology developed and used over the last century, sunlight hits the surface of semiconductor material, one side of which is electron-rich, while the other side is not. The photon, or light particle, excites the electrons, causing them to leave their postions, and create positively-charged "holes." The result is a current of charged particles that can be captured and delivered for various uses, including powering lightbulbs, charging batteries, or facilitating chemical reactions.

"For example, the electrons might cause hydrogen ions in water to be converted into hydrogen, a fuel, while the holes produce oxygen," said Moskovits.

In the technology developed by Moskovits and his team, it is not semiconductor materials that provide the electrons and venue for the conversion of solar energy, but nanostructured metals -- a "forest" of gold nanorods, to be specific.

For this experiment, gold nanorods were capped with a layer of crystalline titanium dioxide decorated with platinum nanoparticles, and set in water. A cobalt-based oxidation catalyst was deposited on the lower portion of the array.

"When nanostructures, such as nanorods, of certain metals are exposed to visible light, the conduction electrons of the metal can be caused to oscillate collectively, absorbing a great deal of the light," said Moskovits. "This excitation is called a surface plasmon."

As the "hot" electrons in these plasmonic waves are excited by light particles, some travel up the nanorod, through a filter layer of crystalline titanium dioxide, and are captured by platinum particles. This causes the reaction that splits hydrogen ions from the bond that forms water. Meanwhile, the holes left behind by the excited electrons head toward the cobalt-based catalyst on the lower part of the rod to form oxygen.

According to the study, hydrogen production was clearly observable after about two hours. Additionally, the nanorods were not subject to the photocorrosion that often causes traditional semiconductor material to fail in minutes.

"The device operated with no hint of failure for many weeks," Moskovits said.

The plasmonic method of splitting water is currently less efficient and more costly than conventional photoprocesses, but if the last century of photovoltaic technology has shown anything, it is that continued research will improve on the cost and efficiency of this new method -- and likely in far less time than it took for the semiconductor-based technology, said Moskovits.

"Despite the recentness of the discovery, we have already attained 'respectable' efficiencies. More importantly, we can imagine achievable strategies for improving the efficiencies radically," he said.

Research in this study was also performed by postdoctoral researchers Syed Mubeen and Joun Lee; grad student Nirala Singh; materials engineer Stephan Kraemer; and chemistry professor Galen Stucky.

 We're liveblogging Nokia's MWC event tomorrow at 2am ET!

The last two events put on by Nokia at Mobile World Congress have been pretty solid affairs -- the PureView 808 last year, preceded by the earth-shattering partnership with Microsoft the year before that -- but we must admit, we're not quite certain as to what we should expect this go-round. Will there be another mystery product that we weren't expecting, such as a tablet or PureView Lumia of some kind? Hard to say, but what is certain is that we'll be there covering it for you. And as an extra bonus, if you want to follow along with us, Nokia is planning to have a live video feed available here as well.

(AP) ? Who'll be the first to feel the sting?

Jobless Americans who have been out of work for a long time and local governments that are paying off loans to fix roads and schools are in tough spots when it comes to the automatic federal budget cuts that are scheduled to kick in Friday.

About 2 million long-term unemployed people could see checks now averaging $300 a week reduced by about $30. There could also be reductions in federal payments that subsidize clean energy, school construction and state and local public works projects. Low-income Americans seeking heating assistance or housing or other aid might encounter longer waits.

Government employees could get furlough notices as early as next week, though cuts in their work hours won't occur until April.

The timing of the "sequester" spending cuts has real consequences for Americans, but it also has a political ramifications. How quickly and fiercely the public feels the cuts could determine whether President Barack Obama and lawmakers seek to replace them with a different deficit reduction plan.

Eager to put pressure on Republican lawmakers to accept his blend of targeted cuts and tax increases Obama has been highlighting the impact of the automatic cuts in grim terms. He did it again on Monday, declaring the threat of the cuts is already harming the national economy.

Republicans say he is exaggerating and point to rates of spending, even after the cuts, that would be higher than in 2008 when adjusted for inflation. All Obama has to do to avoid the damage, House Speaker John Boehner said at the Capitol, is agree to the GOP's recommended spending cuts ? with no tax increases.

By all accounts, most of the pain of the $85 billion in spending reductions to this year's federal budget would be slow in coming. The dire consequences that Obama officials say Americans will encounter ? from airport delays and weakened borders to reduced parks programs and shuttered meatpacking plants ? would unfold over time as furloughs kick in and agencies begin to adjust to their spending reductions.

"These impacts will not all be felt on day one," Obama acknowledged in a meeting with governors at the White House on Monday. "But rest assured the uncertainty is already having an effect."

Homeland Security Secretary Janet Napolitano warned that the federal government would be unable to "maintain the same level of security at all places around the country" once the automatic cuts began to take effect.

The public will feel the results "in the next few weeks," she said, and "it will keep growing."

The majority of the federal budget is in fact walled off from the cuts. Social Security and veterans' programs are exempt, and cuts to Medicare are generally limited to a 2 percent, $10 billion reduction in payments to hospitals and doctors. Most programs that help the poor, like Medicaid, food stamps, subsidized school lunches, Pell Grants and supplemental security income payments are also exempt.

Still, the Pentagon will feel the brunt of half the cuts. Pay for active military is off-limits for cuts, so the rest of the defense budget must absorb the hit. The Obama administration says defense contractors have already ramped down work, contributing to a dip in economic activity in the fourth quarter of last year. The Navy has decided not to deploy an aircraft carrier as planned to the Persian Gulf.

Elsewhere, the White House's budget office says long-term unemployed Americans would lose an average of more than $400 in benefits over the year. The cuts do not affect state unemployment benefits, which jobless workers typically get soon after their loss of work. The federal reductions could begin immediately, though some analysts say the government could delay them for a short period to avoid a harmful hit on the economy.

Bill Hoagland, a former top Republican Senate budget aide and now senior vice president at the Bipartisan Policy Center, a Washington think tank, said the administration must be "betwixt and between" when it comes to addressing reductions in programs like jobless aid.

"They want to make sure the American public knows this sequester is a bad thing, but they also don't want to disrupt the economy too much," he said. "It's not that the reductions won't take place. But they could delay the impact of that until later in the year."

Administration officials also say the Treasury Department is prepared to begin reducing subsidies that cover interest payments by state and local governments on public works, school and renewable energy projects. That means those governments will have to find money in their budgets to make up the difference in bond interest payments, and while that might not affect projects already under way, it could delay new construction efforts.

The sequester, says Douglas Rice of the Center on Budget and Policy priorities, also would mean that families that leave subsidized housing would be less likely to be replaced with people from waiting lists, and that eventually some families could lose their apartments.

Many federal programs, like heating aid for the poor, already have many more people seeking assistance than the program budgets can cover. Funding for the Low Income Home Energy Assistance Program, for instance, has fluctuated greatly in recent years, with the administration proposing to cut it by 13 percent this year. In such cases, it may be impossible for people denied aid to know whether it's because of the sequester since they might have been denied help anyway.

In some instances the cuts will be felt not by beneficiaries being thrown out of programs but by longer delays to get help. In the case of subsidized housing, for example, there are already long waits for assistance in most of the country.

In the case of the Women, Infants and Children program for low-income pregnant women and their children, the government has generally tried to make sure that every eligible woman can get food aid. States aren't permitted to cut the food benefit, which means fewer people will be served. The Agriculture Department says it will prioritize things so that pregnant women and nursing mothers keep their aid but post-partum women who do not breastfeed could lose their aid.

Who gets hit first also depends on how the government's budget flows. Education aid to school districts, for instance, is delivered in the fall, so impacts won't be felt until the new school year. But some teachers are already being informed that they could lose their jobs in August or September. Most Head Start programs won't feel cuts until the upcoming school year, too.

Some programs, like subsidized child care for the poor, are run by states, which will have flexibility in how to allocate the cuts. Just one in six eligible low-income families benefits from a federally funded child care slot. Cuts to the program leave states with difficult options: reduce the number of children cared for, require poor families to contribute more or cut payments to providers.

"I don't think people are going to feel it as dramatically as the administration has been suggesting," said Hoagland. "I'm not questioning the administration's numbers, I'm questioning their timing."

Economists predicting moderate growth in 2013

WASHINGTON (AP) ? Business economists expect 2013 will be another year of sub-par growth for the U.S. economy, reflecting uncertainty stemming from the budget battles in Washington and Europe's on-going debt problems. But they think the economy will improve as the year progresses and by 2014 will grow at the fastest pace in nine years.

In its latest survey of top forecasters, the National Association for Business Economics said it expected the economy, as measured by the gross domestic product, to expand at an annual rate of 2 percent this year, slightly worse than last year's lackluster 2.2 percent growth.

For 2014, however, the NABE forecasters believe the economy will be growing at a rate of 2.8 percent, which would be the best performance since 2005. The GDP, the economy's total output of goods and services, shrank in 2008 and 2009 as the country went through the worst economic contraction since the Great Depression of the 1930s.

Since then economic growth has been modest as the economy has been held back by a variety of factors including prolonged unemployment.

The latest quarterly forecast from NABE is based on responses from 49 forecasters gathered from Jan. 28 through Feb. 5. On growth, it represented a slight downgrade from the survey released in December which forecast the economy would grow 2.1 percent this year.

The NABE panelists were pessimistic about the effects the budget battles in Washington would have on growth. Nearly all felt growth would be reduced this year, given the uncertainty surrounding the budget. One-half of the panelists felt the drag would shave less than one-half percentage point from growth while one-third put the drag at between one-half and a full percentage point knocked off growth this year.

The panelists saw the economy strengthening as the budget uncertainty is resolved. They forecast growth in the second half of this year would average above a rate of 2.5 percent and get stronger next year.

"While the NABE forecasters see fiscal threats, they are optimistic that there will be some resolution toward the second half of this year and that will result in an improvement in many of the numbers is 2014," said Nayantara Hensel, an economics professor at the National Defense University in Washington and a member of the NABE forecasting panel.

The next budget deadline will occur Friday when across-the-board spending cuts totaling $85 billion, known as a sequester, are scheduled to go into effect.

Congress and President Barack Obama averted the so-called fiscal cliff at the end of December with a deal that allowed tax rates to rise on individuals making more than $400,000 and families making more than $450,000 per year. That deal also allowed the temporary 2 percentage point cut in Social Security payroll taxes, which was in effect for two years, to expire.

The tax increases in the fiscal-cliff deal, especially the rise in Social Security payroll taxes, will mean slower growth this year. It will mean that a worker earning $50,000 annually will see his Social Security tax go up by $1,000.

That will slow consumer spending, which accounts for 70 percent of economic activity. The NABE panel forecast consumer spending will rise at an annual rate of 1.9 percent this year but will accelerate in 2014 to a growth rate of 2.5 percent.

The NABE panelists were also pessimistic about Europe's on-going budget troubles, which have hurt the U.S. economy by cutting into export sales. Over one-third of the panelists said they believe Spain will need a larger bailout package this year and one-fourth think that on-going debt troubles in Italy will force that country to take bailout support as well.

"The problems in Europe and our own domestic fiscal drama will keep the investment outlook subdued," said Kenneth Simonson, chief economist for the Associated General Contractors of America and a member of the NABE panel.

Among other predictions in the latest NABE survey:

?Unemployment, currently at 7.9 percent, will decline slowly to 7.5 percent by the end of this year and to 7 percent by the end of 2014, with average monthly job growth of 170,000 this year and 193,000 in 2014.

?Inflation will remain modest at around 2 percent, giving the Federal Reserve leeway to keep a key short-term interest rate at a record low near zero this year and in 2014.

?New home construction, which is finally rebounding after the housing bust, will jump 25.6 percent this year and another 17.3 percent in 2014, pushing construction next year to 1.15 million homes.
