Gates, Zuckerberg champion computer programming in new nonprofit video

SAN FRANCISCO (Reuters) - When Hadi and Ali Partovi immigrated to America from Iran in 1984, they slept in the same cramped bedroom as their parents, who exhausted their life savings on the teenage boys' education.

Nearly 30 years later, the twin brothers are firmly planted in the tech industry's elite circles, after selling companies to Microsoft and News Corp's MySpace, and tapping the rare connections to invest early on in Facebook, Dropbox and Zappos.

Hadi Partovi says the arc of his own successful rise in the tech world was shaped by an early interest in computers and a formal education in writing software, or coding, which enabled that spark to flourish into a career.

Along the way, the twins made influential friends.

Bill Gates, Facebook CEO Mark Zuckerberg and Twitter co-founder Jack Dorsey - three people who became billionaire tech industry luminaries thanks to their computer programming abilities - appear in a new video released Tuesday by the Partovi brothers as part of their new computer science-education nonprofit, Code.org.

The goal of the online video campaign is to encourage parents to demand more schools to teach computer programming ? a potentially lucrative skill that "equalizes opportunity" but is only available to a fraction of U.S. high school students, Hadi Partovi said.

"Computer programming, right now, is the best embodiment of the American Dream," Partovi said. "The American Dream is to be the next Mark Zuckerberg."

"The tragedy is the skills it takes are not hard to learn, but only 10 percent of schools offer (computer science) courses, and these are usually the privileged schools."

After graduating with computer science degrees from Harvard in 1994, the Partovi brothers founded LinkExchange and sold it to Microsoft in 1998 for $250 million. Hadi helped co-found Tellme Networks, a telephony company, while Ali went on to found iLike, a music service that became one of the first apps to integrate with Facebook.

The Partovis' campaign comes at a time tech executives warn of a new digital divide emerging between job-seekers who possess programming skills and those who do not. They also point to statistics showing that while coding jobs are among some of the most well-paid, especially in Silicon Valley, there remains a dearth of computer engineers, who are recruited aggressively by companies like Google and Facebook.

But there have also been strong signs recently that government officials are increasingly raising the issue of technical education, beginning at the secondary level.

In his state of the union speech this month, President Obama vowed to redesign U.S. high schools to meet "the demands of a high-tech economy," while New York Mayor Michael Bloomberg this week introduced a new computer programming pilot program for 20 schools.

Hadi Partovi, who financed the video with his brother, lined up endorsements from Bill Clinton, Al Gore, and American Federation of Teachers union leader Randi Weingarten, although they did not appear on camera. The 10-minute video was directed by Lesley Chilcott, the producer behind the documentaries "An Inconvenient Truth" and "Waiting for Superman."

Partovi said he hoped to eventually raise money to fund programming courses in low-income school districts and perhaps even advocate for certain policy reforms that champion computer science education. In California, he noted for example, computer science courses are not counted toward high school graduation requirements.

"We owe our success in business to having learned to code," Hadi Partovi said.

Although the video mostly contains interviews with tech entrepreneurs and has familiar startup scenes ? like shots of young employees skateboarding inside startup offices ? there are some unexpected appearances by pop celebrities, including Miami Heat forward Chris Bosh and Will.i.am, a part-time startup investor himself.

"Great coders are today's rock stars," the music producer, sitting in his recording studio, says into the camera.

But what is considered a truism in Silicon Valley may not be apparent elsewhere, Hadi Partovi said.

"Middle America doesn't realize it's an issue," he said. "We can't solve the problem until we realize it exists."

Stretchable batteries are here! Power to the bendy electronics

The next frontier in electronics are the flexible, stretchable kind. Yes, that means a rubber, bouncy smartphone (eventually), but it also means heart monitors threaded into cardiac tissue. For devices like that to work, they require flexible, stretchable batteries. And such batteries are here, according to researchers who just published their work.

Yonggang Huang, an engineer at Northwestern University, created the battery with materials wizard John Rogers at the University of Illinois, who received the $500,000 Lemelson-MIT Prize in 2011 for his work on flexible electronics designed for integration with the human body.

How much give and take does the invention allow? ?We can stretch the device a great deal ? up to about 300 percent ? and still have a working battery,? Huang noted. (Please don't try that with your smartphone's battery.)

?Such stretchable batteries enable true integration with stretchable electronics in a small package,? Huang told NBC News in an email.

The background of the research team means that medical applications will be primarily targeted, but there are other applications for bendy batteries such as wearable solar cells and electric-eye cameras that make studio-quality photographs.

The flexible lithium-ion battery reported today in the journal Nature Communications completes the flexible electronics package with a cordless power source. When the battery runs out of juice after about eight hours, it is recharged wirelessly.

To make the battery, the researchers start with tiny, individual, rigid battery storage components arranged next to each other. The bendy and stretchy characteristics stem from tightly packed, wavy wires that connect these components.

?When we stretch the battery, the wavy interconnects unravels, much like yarn unspooling, while the storage components almost keep undeformed, because of their much larger rigidity than the interconnects? Huang explained.

The breakthrough was demonstrated with a light emitting diode that continues to work when stretched, folded and twisted on a human elbow. It continued to work well through 20 recharge cycles.

Gun Control Proposals Separated Into Four Bills, Suggesting Democratic Strategy


* Proposals broken into four bills to improve odds for some
* Strategy suggests ban on assault weapons unlikely to pass
* Senate committee to vote as early as Thursday
By Thomas Ferraro
WASHINGTON, Feb 26 (Reuters) - President Barack Obama's fellow Democrats in the U.S. Senate have spread his gun-control proposals across four bills in an effort to get at least some of the less controversial measures - such as expanded background checks for gun buyers - passed into law.
The Senate Judiciary Committee will vote as early as Thursday on the bills, which together amount to an acknowledgement by Democrats that a ban on military-style "assault" weapons is unlikely to clear Congress.
The proposed ban on assault weapons makes up one of the four gun-control bills, all of which are likely to be approved by the Democrat-led Judiciary Committee and be considered by the full Senate, congressional aides said Tuesday.
Senate Majority Leader Harry Reid, a Democrat from Nevada, will decide how to package the measures for a vote on the Senate floor.
By breaking Obama's gun-control agenda into pieces, supporters hope to avoid having a less popular proposal such as the assault weapons ban contribute to the rejection of other proposals, aides said.
The proposed ban, introduced by Democratic Senator Dianne Feinstein of California, has drawn opposition from Republicans and some Democrats. It will be the focus of a Judiciary Committee hearing on Wednesday.
"We are taking a pragmatic approach that is designed to maximize our options," a senior Democratic aide said.
The four bills now before the Judiciary Committee include one introduced by Democratic Senator Patrick Leahy of Vermont, the panel's chairman, that would crack down on illegal gun trafficking.
Another bill, by California Senator Barbara Boxer, is designed to increase school safety.
A bill, still being finalized, would call for "universal" background checks for all prospective gun buyers. Currently, only about 40 percent of buyers are screened for previous crimes or mental illness.
Feinstein's proposal, targets assault weapons and high-capacity ammunition clips like those used in the Dec. 14 massacre at a school in Newtown, Connecticut, that left 20 children and six adults dead - and inspired the current action on gun control.

'NO WAY' ON ASSAULT WEAPONS BAN
Wednesday's hearing is likely be the latest in a series of dramatic Capitol Hill hearings to reflect the passion surrounding the debate over gun control.
Those scheduled to testify include the father of one of the students killed in Newtown, and a doctor who was in a local emergency room when victims of the shootings were brought in.
Republican Senator Lindsey Graham of South Carolina said Democrats "are trying to create political theater" with the hearing, and that there is no way an assault weapons ban will become law.
"It faces bipartisan opposition," he said.
Even so, all four of the gun-control bills are widely expected to sent to the full Senate on party-line votes of 10-8, Senate aides said.
But to clear procedural roadblocks from Republicans on the Senate floor, the measures will need 60 votes in the 100-member Senate, where Democrats and independents who support them account for 55 seats and Republicans hold 45.
There have been calls from those in both parties for expanded background checks in an effort to keep firearms out of the hands of convicted criminals and the mentally ill.
But a bipartisan deal has not yet been struck despite weeks of talks among four senators - Democrats Charles Schumer of New York and Joe Manchin of West Virginia and Republicans Tom Coburn of Oklahoma and Mark Kirk of Illinois.
"It is the one thing we think can really pass, and we don't yet have an agreement on it," a Senate aide said.
On Tuesday, Coburn said, "We're still talking." (Editing by David Lindsey and Cynthia Osterman)

Graphic shows results of Italy???s election

(AP) ? Political uncertainty in Italy slammed markets hard Tuesday with investors fearful that Europe's debt crisis may be about to rear its head again.

The election has proven so close that final official results are not expected until later Tuesday, at the earliest. But already, the prospect of a political impasse has raised the possibility of further elections down the line.

Though the center-left coalition led by Pier Luigi Bersani appears to have won a narrow victory in the lower house of parliament, the Senate looks split with no party in control.

"Clearly markets are taking fright from the messy and chaotic Italian election result," said Louise Cooper, financial analyst at CooperCity.

In Europe Italy's FTSE MIB index was the worst-performing index, with some of the banking stocks suspended. The index sank around 4.8 percent at the open to 15,583.

The interest rate on the country's benchmark 10-year bond ? an important gauge of investor sentiment ? ratcheted up 0.34 percentage point to 4.78 percent. Meanwhile, investors sought protection in the bonds of more stable and prosperous economies. The interest rate on Germany's 10-year bonds fell 0.07 percentage points to 1.49 percent.

Italy is hugely important for the future of the euro currency. Of the 17 European Union countries that use the euro, it has the second-highest debt burden as a proportion of its annual gross domestic product at 127 percent. Only Greece's is higher.

Over the past year or so, the technocratic government led by Mario Monti, enacted wide-ranging reforms to the budget and the economy. The cost though has been high, with Italy stuck in an 18-month recession and unemployment on the up. Monti was a big loser in the election.

The worry across Europe, and financial markets as a whole, is that the appetite for reform may wane and Italy's parlous debt situation may deteriorate.

The surprise factor was the astonishing vote haul of comic-turned-political leader Beppe Grillo, whose 5 Star Movement capitalized on a wave of voter disgust with the ruling political class.

Though its annual borrowing ? its budget deficit ? is pretty small compared with other euro countries at 3 percent of its gross domestic product, Italy has to splash out around 25 percent of its revenues every year just to service its debt mountain, which stands at around ?2 trillion ($2.65 trillion).

"The election results send a strong signal for change from the electorate who have voted against the traditional political establishment, and the fiscal austerity program endorsed by Europe," said Lee Hardman, an analyst at Bank of Tokyo-Mitsubishi UFJ.

Other stock indexes in Europe opened sharply lower too, following a big retreat in Asia overnight. The Stoxx 50 index of leading European shares was 1.4 percent lower soon after the open. Germany's DAX was down 2.8 percent down at 7,620 while the CAC-40 in France fell 2.6 percent to 3,626. The FTSE 100 index of leading British shares was 1.5 percent lower at 6,260.

The euro has also been hit hard, and was close to $1.30 for the first time since early 2013. It was down 0.1 percent on the day at $1.3062.

The wave of selling in Europe follows big falls on Wall Street and Asia overnight.

In Asia, standout losses were recorded by Japan's Nikkei, which slid 2.3 percent to 11,398 as the yen appreciated to the potential detriment of the country's exporters. The dollar was 0.6 percent lower at $92.06 yen.

Elsewhere in Asia, Hong Kong's Hang Seng dropped 1.3 percent to 22,519 while South Korea's Kospi fell 0.5 percent to 2,000.

Oil prices took a hit too, with the benchmark New York rate 80 cents lower at $92.31 a barrel.

Insight: Syria rebels bolstered by new arms but divisions remain

BEIRUT (Reuters) - Syrian rebels have received advanced weapons aimed at narrowing the arms gap with President Bashar al-Assad's forces and reinforcing a new rebel military command which Western countries hope can dilute the strength of Islamist fighters.

Several rebel commanders and fighters told Reuters that a shipment which reached Syria via Turkey last month comprised shoulder-held and other mobile equipment including anti-aircraft and armor-piercing weapons, mortars and rocket launchers.

Rebels told Reuters the weapons, along with money for cash payments for fighters, were being distributed through a new command structure, part of a plan by foreign backers to centralize control over rebel units and check Islamists linked to al-Qaeda. However, in a sign of the difficulty in uniting disparate fighting groups, some rebels said they had turned down the arms and refused to submit to the new command.

While not nearly enough to tip the military balance against Assad, who is able to deploy air power, missiles and artillery to devastating effect against rebel areas, any significant arms shipment is a boost to rebels who have long complained about the lack of international support.

The rebels refused to specify who supplied the new weapons, saying they did not want to embarrass foreign supporters, but said they had arrived openly via Turkey "from donor countries".

"We have received this shipment legally and normally. It was not delivered through smuggling routes but formally through Bab al-Hawa crossing," said a rebel commander in Homs province, referring to a rebel-held crossing with Turkey.

"But it is not enough to help us win," he told Reuters by Skype. "Another shipment has arrived in Turkey but we haven't received it yet," he added, saying he believed foreign donors were waiting for the Syrian opposition to form a transitional government to work with the rebel command.

The political opposition will meet in Istanbul on Saturday to choose a prime minister in the transitional government, which is also supposed to choose a civilian defense minister - creating the basic structure for a future state and army.

The Syrian revolt erupted nearly two years ago, starting with peaceful protests for reform but developing into an armed insurgency and then civil war as Assad responded to the uprising with ever-growing force. The United Nations estimates that 70,000 people have been killed in the relentless violence.

Although many countries backed Assad's opponents, few have actively supported arming the rebels, fearing that weapons might end up in the hands of hardline Sunni Muslim militants and lead to a repeat of Western conflicts, such as the wars against the Taliban in Afghanistan and al Qaeda-affiliated groups in Iraq.

So far rebels have relied mainly on light weapons smuggled from neighboring countries, many of them financed or sent from sympathizers in Gulf states, and from supplies seized from captured army bases inside Syria.

But video footage and pictures from across the country appear to support assertions that advanced weapons - with origins as varied as the former Yugoslavia and China - have ended up in rebel hands.

A Reuters photographer in Damascus over the last month saw several Western-built rebel firearms- including U.S. pattern M4 and Austrian Steyr assault rifles - that almost certainly came from outside the country.

STRENGTHENING REBEL COMMAND

Assad's strongest regional supporter has been Shi'ite Muslim Iran, while the leading campaigners for arming the rebels are the Sunni Muslim Gulf Arab powers Qatar and Saudi Arabia, reflecting the strong sectarian currents of the Syrian uprising.

Although Saudi Arabia and Qatar do not discuss specific weapons shipments to the rebels, both countries have been open about their support for arming them in principle.

Saudi Foreign Minister Saud al-Faisal bluntly told a news conference in Riyadh on February 12: "My country believes that the brutality of the Syrian regime against its own people requires empowering the people to defend itself."

Qatari Prime Minister Sheikh Hamad bin Jassim bin Jabr al-Thani said last week: "As there is no clear international opinion to end the crisis in Syria...we are supporting the opposition with whatever it needs, even if it takes up arms for self-defense."

Western countries have been more cautious, and have so far committed publicly to sending only "non-lethal" aid, like radios and body armor.

International powers are alarmed by the growing influence of Islamist hardliners in a country which lies at the crossroads of the Middle East between Iraq, Israel, Turkey, Lebanon and Jordan. They have made efforts to unite Syrian rebels under a clear leadership. A body was formed in December to bring the rebel units, or brigades, together under a unified command.

"One of the reasons for the change in the donors' minds is that they want to empower the new military command. They want to help it organize the weapons and the fighters," said an aide to a rebel commander in a province which has seen some of the heaviest fighting.

"If the brigades join then they get their share of these weapons and also monthly payment for the fighters."

The new military command divides Syria into five fronts - southern, western, eastern, northern and central.

"Each front has received its share. All equally distributed," the rebel said, adding that 'payment' for the weapons would come in the form of post-conflict reconstruction contracts in Syria awarded to countries that helped.

"So basically it's like we have paid in advance. It is funded by the countries that will be involved in reconstruction of Syria," he said.

But in a sign of the continued divisions among Assad's foes, some rebels complain that the "military councils" who received the weapons - and are seen by the West as more likely allies than the hardline Islamists - were the wrong groups to arm.

"There is a dispute in Damascus. The people who received these weapons are not the real fighters. They gave it to the military council which is not fighting," said a rebel commander operating around the Syrian capital. "We are the ones that are on the frontline and we are the fighters."

He said his fighters had rejected an offer of weapons in return for their allegiance to the military councils.

"There was a meeting and they asked for our brigade to join so they will give us between 10 to 20 rockets and armor-piercing ammunition and other stuff," he said. "They wanted everything to be under their supervision, but we refused."

"They are giving these weapons to people to allow them to create a (fighting) presence on the ground. Why don't they give it to people who already have a presence?"

Another commander said he would have no qualms about seizing weapons destined for rebels nominally fighting on the same side as him, if he knew they were passing through his territory.

REBELS NEED "ARMS, NOT MEN"

Several fighters from across the country who spoke to Reuters in February said they feared the ultimate plan of outside powers was to push the rebel Free Syrian Army and other "moderate" Islamist fighters into confrontation with radicals.

Fighters from hardline groups such as Jabhat al-Nusra and the Islamist Ahrar al-Sham have waged some of the deadliest attacks in Syria, including car bombings in Damascus, Aleppo and elsewhere. Their ranks have been swollen by jihadi fighters from around the Muslim world.

The chief of staff of the rebel military command, Brigadier Selim Idris, said the presence of foreign fighters was hindering international support for the battle against Assad.

"We call all brothers from all the countries. Please, my brothers: we do not need men. Stay in your own countries and do something good inside your own countries," he told Reuters.

"If you want to help us just send us weapons or funding - or even pray for us. But you do not have to come to Syria. We have enough Syrian men fighting."

Idris denied receiving weapons from donors and said that weapons are still entering Syria through the black market - apparently reluctant to put foreign powers in the spotlight.

"We are not receiving weapons from the Europeans, we do not want to embarrass them, we do not want to embarrass anyone with the weapons issue," he said.

Previous attempts to unify Syria's divided rebels have foundered on local rivalries and competition for money and influence. Some have grown rich and powerful by smuggling weapons, medical supplies, food and diesel, while the lack of civil administration in rebel controlled areas has also encouraged the proliferation of autonomous rebel groups.

Seeking to address those divisions, the military councils hope to pay fighters a symbolic monthly salary of $100, funded in part by donations from the Gulf. The Homs commander said one Gulf state had recently paid $15 million towards their wages.

"They want to organize the rebels and have them all under one command - who joins will be eligible to receive the money and the weapons," he said. "This is all for organization purposes."

"If a brigade joins then it will take its share, if it doesn't, then no weapons. We want to be organized," he said.

ZTE launches 4G Cloud Radio networking solutions

ZTE

ZTE does more than make Android phones that we rarely see in the U.S. They're also a big vendor to the folks who build out cellular networks, and provide all manner of equipment to folks like Verizon and other carriers. Today at Mobile World Congress 2013 they have launched what they are calling a 4G Cloud Radio solution.

Android Central at Mobile World Congress

It's technical, and a look at the white papers and press release is bound to bring on some serious head scratching for even the most seasoned smartphone veteran. In a nutshell, "cloud radio allows operators to address interference and coordination that affect OAM and arise as a result of the coexistence of multistandard networks. Wireless network performance can be optimized for given bearer resources, and user experience can be significantly improved. Cloud radio also protects investment, increases revenue, and helps operators secure a leading position in the wireless market."

I told you it was complicated. What we, as users, need to take away from this is that this new technology will allow carriers and the industry as a whole to make the transition from legacy 2G networks to 4G LTE smoother, more cost effieient, and cheaper. All of that trickles down to us and is reflected in our monthly bill. The full press release is after the break.

Can escape clause save voting rights provision?

WASHINGTON (AP) ? The Obama administration and civil rights groups are defending a key section of the landmark voting rights law at the Supreme Court by pointing reformed state, county and local governments to an escape hatch from the law's strictest provision.

The Voting Rights Act effectively attacked persistent discrimination at the polls by keeping close watch, when it comes to holding elections, on those places with a history of preventing minorities from voting. Any changes, from moving a polling place to redrawing electoral districts, can't take effect without approval from the Justice Department or federal judges in Washington.

But the Voting Rights Act allows governments that have changed their ways to get out from under this humbling need to get permission through a "bailout provision." Nearly 250 counties and local jurisdictions have done so; thousands more could be eligible based on the absence of recent discriminatory efforts in voting.

The viability of the bailout option could play an outsized role in the Supreme Court's consideration of the voting rights law's prior approval provision, although four years ago, conservative Justice Clarence Thomas said the prospect of bailing out had been "no more than a mirage."

The court will hear arguments Wednesday in the case, which is among the term's most important, in a challenge from Shelby County, Ala.

Opponents of the law say they no longer should be forced to live under oversight from Washington because the country has made enormous racial progress, demonstrated most recently by the re-election of President Barack Obama. They object in particular to the 40-year-old formula by which some jurisdictions, most in the Deep South, are swept under the law and others remain outside it.

The administration and its allies acknowledge that there has been progress. But they say minority voters still need the protection the law affords from efforts to reduce their influence at the polls. Last year, federal judges in two separate cases blocked Texas from putting in place a voter identification law and congressional redistricting plan because they discriminated against black and Hispanic residents.

Obama himself talked about the case in a radio interview last week. He told SiriusXM host Joe Madison that if the law were stripped of its advance approval provision, "it would be hard for us to catch those things up front to make sure that elections are done in an equitable way."

Also, the law's defenders say places that have changed their ways can win release from having to get Washington's blessing for election changes. Governments seeking to exit have to show that they and the smaller jurisdictions within their borders have had a clean record, no evidence of discrimination in voting, for the past 10 years.

Shelby County has never asked to be freed from the law, but would seem to be ineligible because one city in the county, Calera, defied the voting rights law and prompted intervention by the Bush Justice Department.

Yet places with a long, well-known history of discrimination probably could find their way out from under federal monitoring, according to a prominent voting rights lawyer who used to work for the Justice Department.

"Birmingham, Ala., where they used to use fire hoses on people, may well be eligible to bail out," said the lawyer, Gerry Hebert. Birmingham officials said they've never considered asking.

The Supreme Court made clear its skepticism about the ongoing need for the law when it heard a similar case in 2009. "Past success alone, however, is not adequate justification to retain the preclearance requirements," Chief Justice John Roberts said for the court. That ruling sidestepped the constitutional issue and instead expanded the ability of states, counties and local governments to exit the advance approval process.

At that point, so few governments had tried to free themselves from the advance approval requirement that, in 2009, Thomas said the "promise of a bailout opportunity has, in the great majority of cases, turned out to be no more than a mirage."

At the time, Thomas said, only a handful of the 12,000 state, county and local governments covered by the law had successfully bailed out.

The overall numbers remain low, but the Obama administration argues that "the rate of successful bailouts has rapidly increased" since the high court last took up the Voting Rights Act nearly four years ago.

In the past 12 months, 110 local governments have been freed from the requirement to show in advance that their proposed election changes are not discriminatory. Places that have won their release from coverage include Prince William County, Va., with more than 400,000 residents, and Merced County, Calif., and its 84 municipalities.

Shelby County says that even with the recent jump in bailouts, "only a tiny percentage" of governments have found their way out of oversight from Washington.

The advance approval was adopted in the Voting Rights Act in 1965 to give federal officials a potent tool to defeat persistent efforts to keep blacks from voting.

The provision was a huge success, and Congress periodically has renewed it over the years. The most recent time was in 2006, when a Republican-led Congress overwhelmingly approved and President George W. Bush signed a 25-year extension.

The requirement currently applies to the states of Alabama, Alaska, Arizona, Georgia, Louisiana, Mississippi, South Carolina, Texas and Virginia. It also covers certain counties in California, Florida, New York, North Carolina and South Dakota, and some local jurisdictions in Michigan and New Hampshire. Coverage has been triggered by past discrimination not only against blacks, but also against American Indians, Asian-Americans, Alaskan Natives and Hispanics.

The 10 covered towns in New Hampshire are poised to become the next places to win their release from the law. An agreement between the Justice Department and the state is awaiting approval from a federal court in Washington.

Critics of the law contend the Justice Department is highlighting the escape hatch and agreeing to allow places such as the New Hampshire towns to exit to try to make the entire law look more palatable to the court.

Alaska Attorney General Michael Geraghty says in his court filing in support of Shelby County that the Justice Department "commonly agrees to bailouts for jurisdictions that are not legally entitled to receive them."

But supporters of the law argue in response that the federal government's willingness to agree to free places from the need to get permission shows that the voting rights act is flexible and helps focus attention on potentially discriminatory voting schemes.

Scientists find bone-marrow environment that helps produce infection-fighting T and B cells

Feb. 24, 2013 ? The Children's Medical Center Research Institute at UT Southwestern has deepened the understanding of the environment within bone marrow that nurtures stem cells, this time identifying the biological setting for specialized blood-forming cells that produce the infection-fighting white blood cells known as T cells and B cells.

The research found that cells called early lymphoid progenitors, which are responsible for producing T cells and B cells, thrive in an environment known as an osteoblastic niche. The investigation, published online February 24 in Nature and led by Dr. Sean Morrison, also establishes a promising approach for scientists to map the entire blood-forming system.

Scientists already know how to manufacture large quantities of stem cells that give rise to the nervous system, skin, and other tissues. But they have been unable to make blood-forming stem cells in a laboratory, in part because of a lack of understanding about the niche in which blood-forming stem cells and other progenitor cells reside in the body.

"We believe this research moves us one step closer toward the development of cell therapies in the blood-forming system that don't exist today," said Dr. Morrison, Director of the Institute and Professor of Pediatrics at UT Southwestern Medical Center. "In understanding the environments for blood-forming stem cells and those of different kinds of progenitor cells, we can work toward reproducing those environments in the lab and growing cells that can be transplanted to treat a host of medical conditions."

These findings eventually may help increase the safety and effectiveness of bone-marrow transplants, such as those needed after healthy marrow is destroyed by radiation or chemotherapy treatments for childhood leukemia, Dr. Morrison said. The findings also may have implications for treating illnesses associated with loss of infection-fighting cells, such as HIV and severe combined immunodeficiency disease, better known as bubble boy disease.

The Nature study augments earlier work by Dr. Morrison and his team that showed endothelial cells and perivascular cells lining the blood vessels in the bone marrow create the environment that maintains haematopoietic stem cells, which produce billions of new blood cells every day. The latest study shows that bone-forming cells create the environment that maintains early lymphoid progenitors.

"Our research documents that there are different niches, or microenvironments, for blood-forming stem cells and restricted progenitors in the bone marrow," Dr. Morrison said. "One way that bone marrow makes different kinds of blood-forming cells is by compartmentalizing them into different neighborhoods within the marrow."

The researchers identified niches for stem cells and early lymphoid progenitors by determining which cells are the sources of a growth factor (CXCL12) necessary for the proliferation of those two populations of blood-forming cells. By taking the same approach for other growth factors in the bone marrow, researchers should be able to map the niches for every kind of blood-forming progenitor cell in the bone marrow, Dr. Morrison said.

The UTSW paper's first author is Dr. Lei Ding, a former postdoctoral research fellow at the Children's Research Institute and the Howard Hughes Medical Institute (HHMI) at UT Southwestern. Dr. Ding is now an assistant professor at Columbia University.

Research support came from the HHMI and the National Heart, Lung, and Blood Institute.

MiamiHerald.com - Can escape clause save voting rights provision - Politics Wires - WASHINGTON - MiamiHerald.com

The Obama administration and civil rights groups are defending a key section of the landmark voting rights law at the Supreme Court by pointing reformed state, county and local governments to an escape hatch from the law's strictest provision.

The Voting Rights Act effectively attacked persistent discrimination at the polls by keeping close watch, when it comes to holding elections, on those places with a history of preventing minorities from voting. Any changes, from moving a polling place to redrawing electoral districts, can't take effect without approval from the Justice Department or federal judges in Washington.

But the Voting Right Act allows governments that have changed their ways to get out from under this humbling need to get permission through a "bailout provision." Nearly 250 counties and local jurisdictions have done so; thousands more could be eligible based on the absence of recent discriminatory efforts in voting.

The viability of the bailout option could play an outsized role in the Supreme Court's consideration of the voting rights law's prior approval provision, although four years ago, conservative Justice Clarence Thomas said the prospect of bailing out had been "no more than a mirage."

The court will hear arguments Wednesday in the case, which is among the term's most important, in a challenge from Shelby County, Ala.

Opponents of the law say they no longer should be forced to live under oversight from Washington because the country has made enormous racial progress, demonstrated most recently by the re-election of President Barack Obama. They object in particular to the 40-year-old formula by which some jurisdictions, most in the Deep South, are swept under the law and others remain outside it.

The administration and its allies acknowledge that there has been progress. But they say minority voters still need the protection the law affords from efforts to reduce their influence at the polls. Last year, federal judges in two separate cases blocked Texas from putting in place a voter identification law and congressional redistricting plan because they discriminated against black and Hispanic residents.

Obama himself talked about the case in a radio interview last week. He told SiriusXM host Joe Madison that if the law were stripped of its advance approval provision, "it would be hard for us to catch those things up front to make sure that elections are done in an equitable way."

Also, the law's defenders say places that have changed their ways can win release from having to get Washington's blessing for election changes. Governments seeking to exit have to show that they and the smaller jurisdictions within their borders have had a clean record, no evidence of discrimination in voting, for the past 10 years.

Shelby County has never asked to be freed from the law, but would seem to be ineligible because one city in the county, Calera, defied the voting rights law and prompted intervention by the Bush Justice Department.

Yet places with a long, well-known history of discrimination probably could find their way out from under federal monitoring, according to a prominent voting rights lawyer who used to work for the Justice Department.

"Birmingham, Ala., where they used to use fire hoses on people, may well be eligible to bail out," said the lawyer, Gerry Hebert. Birmingham officials said they've never considered asking.

Laser mastery narrows down sources of superconductivity

Feb. 24, 2013 ? Identifying the mysterious mechanism underlying high-temperature superconductivity (HTS) remains one of the most important and tantalizing puzzles in physics. This remarkable phenomenon allows electric current to pass with perfect efficiency through materials chilled to subzero temperatures, and it may play an essential role in revolutionizing the entire electricity chain, from generation to transmission and grid-scale storage. Pinning down one of the possible explanations for HTS -- fleeting fluctuations called charge-density waves (CDWs) -- could help solve the mystery and pave the way for rapid technological advances.

Now, researchers at the Massachusetts Institute of Technology and the U.S. Department of Energy's Brookhaven National Laboratory have combined two state-of-the-art experimental techniques to study those electron waves with unprecedented precision in two-dimensional, custom-grown materials. The surprising results, published online February 24, 2013, in the journal Nature Materials, reveal that CDWs cannot be the root cause of the unparalleled power conveyance in HTS materials. In fact, CDW formation is an independent and likely competing instability.

"It has been difficult to determine whether or not dynamic or fluctuating CDWs even exist in HTS materials, much less identify their role," said Brookhaven Lab physicist and study coauthor Ivan Bozovic. "Do they compete with the HTS state, or are they perhaps the very essence of the phenomenon? That question has now been answered by targeted experimentation."

Custom-grown Superconductors

Electricity travels imperfectly through traditional metallic conductors, losing energy as heat due to a kind of atomic-scale friction. Impurities in these materials also cause electrons to scatter and stumble, but superconductors can overcome this hurdle -- assuming the synthesis process is precise.

For this experiment, Bozovic used a custom-built molecular beam epitaxy system at Brookhaven Lab to grow thin films of LaSrCuO, an HTS cuprate (copper-oxide) compound. The metallic cuprates, assembled one atomic layer at a time, are separated by insulating planes of lanthanum and strontium oxides, resulting in what's called a quasi-two-dimensional conductor. When cooled down to a low enough temperature -- less than 100 degrees Kelvin -- strange electron waves began to ripple through that 2D matrix. At even lower temperatures, these films became superconducting.

Electron Sea

"In quasi-two-dimensional metals, low temperatures frequently bring about interesting collective states called charge-density waves," Bozovic said. "They resemble waves rolling across the surface of a lake under a breeze, except that instead of water, here we actually have a sea of mobile electrons."

Once a CDW forms, the electron density loses uniformity as the ripples rise and fall. These waves can be described by familiar parameters: amplitude (height of the waves), wavelength (distance between waves), and phase (the wave's position on the material). Detecting CDWs typically requires high-intensity x-rays, such as those provided by synchrotron light sources like Brookhaven's NSLS and, soon, NSLS-II. And even then, the technique only works if the waves are essentially frozen upon formation. However, if CDWs actually fluctuate rapidly, they may escape detection by x-ray diffraction, which typically requires a long exposure time that blurs fast motion.

Measuring Rolling Waves

To catch CDWs in action, a research group at MIT led by physicist Nuh Gedik used an advanced ultrafast spectroscopy technique. Intense laser pulses called "pumps" cause excitations in the superconducting films, which are then probed by measuring the film reflectance with a second light pulse -- this is called a pump-probe process. The second pulse is delayed by precise time intervals, and the series of measurements allow the lifetime of the excitation to be determined.

In a more sophisticated variant of the technique, largely pioneered by Gedik, the standard single pump beam is replaced by two beams hitting the surface from different sides simultaneously. This generates a standing wave of controlled wavelength in the film, but it disappears rapidly as the electrons relax back into their original state.

This technique was applied to the atomically perfect LaSrCuO films synthesized at Brookhaven Lab. In films with a critical temperature of 26 degrees Kelvin (the threshold beyond which the superconductivity breaks down), the researchers discovered two new short-lived excitations -- both caused by fluctuating CDWs.

Gedik's technique even allowed the researchers to record the lifetime of CDW fluctuations -- just 2 picoseconds (a millionth of a millionth of a second) under the coldest conditions and becoming briefer as the temperatures rose. These waves then vanished entirely at about 100 Kelvin, actually surviving at much higher temperatures than superconductivity.

Ruling out a Suspect

The researchers then hunted for those same signatures in cuprate films with slightly different chemical compositions and a greater density of mobile electrons. The results were both unexpected and significant for the future of HTS research.

"Interestingly, the superconducting sample with the highest critical temperature, about 39 Kelvin, showed no CDW signatures at all," Gedik said.

The consistent emergence of CDWs would have bolstered the conjecture that they play an essential role in high-temperature superconductivity. Instead, the new technique's successful detection of such electron waves in one sample but not in another (with even higher critical temperature) indicates that another mechanism must be driving the emergence of HTS.

"Results like this bring us closer to understanding the mystery of HTS, considered by many to be one of the greatest problems in physics today," Bozovic said. "The source of this extraordinary phenomenon is slowly but surely running out of places to hide."

Raising the Minimum Wage Is Good for Business - Huffington Post

As soon as President Barack Obama called on Congress to raise the minimum wage to $9 an hour in his State of the Union address last week, you could see Speaker John Boehner, seated behind the president, uttering his religious mantra: "Job killer." And even if you couldn't read his lips, you could read his mind: "Campaign contributions." He and his Republican colleagues could expect huge donations from business lobby groups -- especially those that depend on low-wage workers, like the hotel industry, restaurants and fast-food chains, nursing homes and hospitals and big-box retailers -- to keep Congress from embracing Obama's modest proposal.

Boehner's "job killer" grumble should come as no surprise. Business groups and their political allies have been "crying wolf" about the minimum wage ever since President Franklin D. Roosevelt proposed it during the Depression to help stimulate the economy. The critics warned that enacting a minimum wage would destroy employees' drive to work hard and would force many firms out of business. The minimum wage law, warned the National Association of Manufacturers (NAM) in 1937, "constitutes a step in the direction of communism, bolshevism, fascism, and Nazism." Congressman Edward Cox, a Georgia Democrat, said that the law "will destroy small industry." These ideas, Cox claimed, "are the product of those whose thinking is rooted in an alien philosophy and who are bent upon the destruction of our whole constitutional system and the setting up of a Red Labor communistic despotism upon the ruins of our Christian civilization." Roosevelt and most members of Congress ignored these warnings and adopted the Fair Labor Standards Act in 1938, establishing the federal minimum wage of 25 cents an hour.

Since then, each time Congress has considered raising the minimum wage, business groups and conservatives have repackaged the same arguments. In 1945, NAM claimed that, "The proposed jump from an hourly minimum of 40 to 65 cents at once, and 70 and 75 cents in the following years, is a reckless jolt to the economic system. Living standards, instead of being improved, would fall -- probably to record lows." Instead, the next three decades saw the biggest increased in living standards in the nation's history.

In 1975, economist Milton Friedman, a conservative guru, said: "The consequences of minimum wage laws have been almost wholly bad, to increase unemployment and to increase poverty. In my opinion there is absolutely no positive objective achieved by minimum wages." While campaigning for president, Ronald Reagan said, "The minimum wage has caused more misery and unemployment than anything since the Great Depression." In 2004, David Brandon, the CEO of Domino's Pizza, declared: "From our perspective, raising the minimum wage is a job killer." Earlier this month, Jason Riley, a Wall Street Journal editorial writer, called the minimum wage a "proven job killer" on the newspaper's cable talk show.

Following Obama's State of the Union address, business representatives and conservative media pundits echoed the same talking points. Analyzing Obama's speech for Fox News, Nina Easton, an editor for Fortune magazine, repeated the claim that increasing the minimum wage is a "job killer." Michael Saltsman, research director at the business-backed Employment Policies Institute, told Fox Business News that "minimum wage hikes lead to job losses." Bill Herrle, executive director of the National Federation of Independent Business' Florida affiliate, told Sunshine State News that Obama's plan was a "job killer."

But such dire predictions have never materialized. That's because they're bogus. In fact, raising the minimum wage is good for business and the overall economy. Why? Because when poor workers have more money to spend, they spend it, almost entirely in the local community, on basic necessities like housing, food, clothing and transportation. When consumer demand grows, businesses thrive, earn more profits, and create more jobs. Economists call this the "multiplier effect." According to Doug Hall of the Economic Policy Institute, a minimum wage hike to $9 would pump $21 billion into the economy.

Moreover, since most minimum wage jobs are in "sticky" (immobile) industries -- such as restaurants, hotels, hospitals and nursing homes and retail stores -- that can't flee overseas, raising the level doesn't lead to job flight. Not surprisingly, the National Restaurant Association is, along with the U.S. Chamber of Commerce, one of the fiercest opponents of a minimum wage hike.

In recent years, the nation's job growth has been concentrated in low-wage sectors, led by Walmart, the nation's largest private employer, whose pay levels are so low that many employees are eligible for food stamps. More than one-quarter of all jobs pay poverty-level wages. According to a National Employment Law Project study, the majority of new jobs created since 2010 pay just $13.83 an hour or less. This has contributed to the nation's widening economic inequality. Nobel laureate economist Joseph Stiglitz recently said, "Increasing inequality means a weaker economy" for all of us.

Meanwhile, of course, the incomes of the wealthiest Americans -- including the corporate CEOs who lobby against raising the minimum wage -- have skyrocketed. Since 1993, the incomes of the richest 1 percent of Americans increased by 57.5 percent, while the incomes of the bottom 99 percent increased by only 5.8 percent, according to studies by economist Emmanuel Saez at the University of California at Berkeley. Since 2009, as the country was emerging from the recession, the wealthiest one percent saw their incomes grow by 11.2 percent while the rest of Americans watched their incomes shrink by 0.4 percent. In other words, the richest 1 percent -- those with incomes over $600,000 -- captured almost all of the income gains in the first two years of the recovery.

The last time Congress raised the federal minimum wage was in 2007, when President George W. Bush reluctantly signed the bill passed by the Democratic Congress to raise the federal minimum wage from $5.15 an hour (where it had stood for ten years) to $7.25 an hour (phased in over several years). It has remained at $7.25 since 2009. A full-time worker who earns the current minimum wage makes only $15,080 a year. According to "Out of Reach," a report sponsored by the National Low-Income Housing Coalition, in no state can an individual working full time at the minimum wage afford an apartment for his or her family.

In fact, the minimum wage has fallen in value because Congress hasn't raised it to keep up with inflation. At its peak in 1968, the minimum wage was equal to about $10.50 an hour in today's dollars. That's a 25 percent decline in buying power.

Frustrated by Congress' intransigence, a growing number of states have made an end run around Washington. Nineteen states now have minimum wages over $7.25 an hour. The highest is in Washington State, where the minimum wage is $9.19 an hour.

Cities, too, have enacted laws raising pay for low-wage workers. In 2003, Santa Fe, New Mexico adopted a citywide $8.50 an hour living-wage law with regular cost-of-living increases. At the time, Sam Goldenberg, a business leader, predicted that the law "would be a disaster for the businesses in Santa Fe." And restaurateur Al Lucero called the plan economically irresponsible and argued that "people will be so content with $8.50 or $10.50 an hour that they'll have no desire to improve themselves."

Nearly 10 years later, the rate is now $10.29 an hour, and Santa Fe has one of the lowest unemployment rates in the state at 5.1 percent. Jeff Mitchell, a senior research scientist at the University of New Mexico's Bureau of Business and Economic Research, found "no evidence of adverse effects" from the wage hike. Santa Fe's tourism industry is doing fine. Travel + Leisure magazine last year listed Santa Fe in its top 10 U.S. and Canadian travel destinations for the 11th consecutive year.

In 2003, San Francisco voters also adopted a citywide minimum-wage law. The Golden Gate Restaurant Association called it a job killer that would "bankrupt many restaurants." The Association of Realtors said that many hospitality industry workers were "likely to receive pink slips and join the ranks of the unemployed."

Wrong again. A 2007 study by University of California economists found that after San Francisco's minimum wage went up, restaurant growth was higher in the city than in neighboring East Bay cities. In December 2012, the city's unemployment rate was 6.5 percent, well below the statewide average, and job growth in bars and restaurants has led the region's post-recession recovery.

In November, voters in Albuquerque and San Jose passed ballot measures that will raise the minimum wage for workers in those cities. Albuquerque's citywide minimum wage rose from $7.50 to $8.50 per hour last month and will automatically adjust in future years with inflation. In San Jose, the minimum wage will increase from $8 per hour -- the current minimum wage in California -- to $10 per hour starting next month and will adjust automatically in future years to keep pace with the rising cost of living.

Since 1994, about 200 cities have passed "living wage laws" that set minimums for workers for private companies that have municipal contracts, get local tax breaks or rely on city facilities. In November, for example, voters in Long Beach, California passed a ballot measure that raises the minimum wage for hotel workers in that tourist city to $13 per hour and guarantees hotel workers five paid sick days per year. A recent study by William Lester of the University of North Carolina and Ken Jacobs of the University of California-Berkeley found no difference in employment levels between comparable cities with and without living wage laws. They disproved the claim by that these laws drive away business or lead to reduced employment.

Most Americans agree that workers who toil full time shouldn't be stuck in poverty. According to a national poll conducted last year, almost three-quarters (73 percent) of Americans support increasing the minimum wage to $10 per hour and indexing it to inflation. The same poll showed 50 percent of Republicans and 74 percent of Independents favoring an increase in the minimum wage. Majorities of every major religious group support raising the minimum wage to $10. Sen. Tom Harkin (D-Iowa) and Rep. George Miller (D-California) have been working on a proposal to raise the minimum wage to $10.10 indexed to inflation.

In his State of the Union address, Obama proposed to gradually raise the minimum wage so that it hits $9 an hour in 2015. "Let's declare that in the wealthiest nation on earth, no one who works full time should have to live in poverty," he said. In fact, a full-time employee earning $9 an hour would make about $18,720 a year, slightly below the official poverty level of $19,530 for a family of three. Under Obama's plan, at least 15 million workers would directly benefit from a higher minimum wage. Millions more would get pay raises as the entire wage scale moves up.

Corporate America and Congressional Republicans are particularly upset that Obama's plan includes a cost-of-living adjustment, which would automatically increase the minimum wage each year to adjust for inflation. Most businesses don't like the idea of having to give employees regular pay hikes. And the Republicans hate the idea because it would eliminate their ability to keep the wage flat by refusing to raise it legislatively. Ten states -- Arizona, Colorado, Florida, Missouri, Montana, Nevada, Ohio, Oregon, Vermont and Wisconsin -- include a cost-of-living adjustment in their minimum wage laws. This is not a radical idea. Since 1975, Social Security has had an automatic cost of living adjustment for benefit levels.

Although the evidence supports the advocates of a higher minimum wage, the battle to raise the federal minimum wage won't be easy, because business lobby groups have put enormous pressure on members of Congress to resist this common sense policy. In addition to pouring big bucks into campaign contributions and lobbying, they've also paid huge sums to conservative economists and business-sponsored think tanks like the American Enterprise Institute to come up with misleading arguments about why giving Americans a raise is a bad idea. They generally argue that a minimum wage increase will particularly hurt small businesses -- a view that the media often repeat with misleading anecdotes.

For example, the day after Obama's State of the Union speech, NPR interviewed a California restaurant owner (who now pays workers the state's $8 per hour minimum) who claimed that he'd have to lay off employees or cut back their hours if Congress raised the federal minimum wage to $9. But while this may be true of a handful of small businesses, the overall impact of lifting the minimum wage is good for business. Restaurants may have to slightly increase their payroll expenses, but they'll benefit when customers have more money to spend, thanks to a minimum wage increase.

Indeed, contrary to business rhetoric, studies reveal that that higher minimum wage levels do not force employers to lay off workers. In a study published in the Review of Economics and Statistics, economists Arin Dube, William Lester and Michael Reich compared counties adjacent to state borders, where one state raised the minimum wage and another did not, between 1990 and 2006.

They found conclusively that raising the minimum wage had no impact on employment. A similar study by Alan Krueger -- now the head of the Council of Economic Advisers -- came to the same conclusion. The Obama White House also noted that Costco, the retail discount chain, Stride Rite, a children's shoe chain, and other firms have supported increasing the minimum wage, saying it reduces employee turnover and improves workers' productivity.

These positive arguments won't stop business lobby groups and Republican leaders from trying to block President Obama's modest proposal. Speaker Boehner, who opposed the last minimum wage boost in 2006 when the Democrats controlled the House, said this week, "When you raise the price of employment, guess what? You get less of it.... Why would we want to make it harder to small employers to hire people?" Sen. Marco Rubio of Florida, who delivered the Republicans' response to Obama's State of the Union address, said "I don't think a minimum-wage law works," on CBS This Morning.

But if democracy is about translating public opinion into public policy, Americans are overdue for a raise. Increasing the minimum wage to $9 an hour and tying it to the cost of living will not, on its own, lift the country out of its economic doldrums. But it will definitely lift millions of Americans out of poverty, stimulate the economy, and create new jobs. It is the right thing to do both morally and economically.

NATO considers post-2014 Afghan force of 8,000-12,000

BRUSSELS (Reuters) - NATO Allies are discussing keeping a training force of between 8,000 and 12,000 troops in Afghanistan after most foreign soldiers leave in 2014, the United States said on Friday.

NATO-led forces are gradually handing over responsibility for security to their Afghan counterparts as the bulk of foreign combat forces prepare to withdraw by the end of next year.

"A range of 8-12,000 troops was discussed as the possible size of the overall NATO mission," Pentagon spokesman George Little said after a NATO defence ministers' meeting in Brussels.

U.S. President Barack Obama has not decided how many American troops would remain in Afghanistan after 2014, he said, adding: "The president is still reviewing options."

German Defence Minister Thomas de Maiziere said earlier that U.S. Defense Secretary Leon Panetta had told allies in Brussels that the United States alone could keep 8,000 to 12,000 troops.

After Panetta denied this, de Maiziere issued a statement correcting himself and saying the number referred to the possible overall size of the post-2014 NATO mission, also expected to include European allies and some non-NATO nations.

Troop numbers are politically sensitive as voters in many allied countries are weary of the 12-year war with the Taliban.

Previous discussions at the White House focused on a range of options of between 3,000 and 9,000 U.S. troops, with military commanders most comfortable with the higher-end figures.

A senior NATO officer said last month the United States expects other NATO allies to contribute between a third and a half of the number of troops that Washington provides.

Apart from the NATO training mission, the United States will also lead a counter-terrorism mission in Afghanistan after 2014, targeting al Qaeda.

REGIONS

NATO allies agreed in Brussels the trainers will be stationed in the capital Kabul and in four regional headquarters, where they can advise Afghan military commanders.

"Today we asked NATO to begin planning for a range of options on the post-2014 posture that would provide for an effective regional presence not only in Kabul but at fixed sites in the north, south, the east and the west," Panetta told a news conference in Brussels.

The NATO talks about the residual force in Afghanistan came just over a week after Obama announced the withdrawal of roughly half of the 66,000 U.S. forces by early next year.

Panetta confirmed the bulk of the U.S. forces in Afghanistan would remain through the summer, allowing more than 60,000 of them to assist Afghans through peak fighting months.

U.S. troop levels would fall to about 50,000 by November this year. Panetta said the United States would keep some 34,000 troops in the country through the April 2014 Afghan presidential election to assist with security.

"Once those elections were completed, we would then begin the final drawdown of our forces towards the end of 2014," he said.

NATO is strongly considering keeping Afghan forces, largely funded by the United States and its allies, at their peak strength of 352,000 until at least 2018, as opposed to cutting them by about a third after 2015. This would cost an extra $2 billion over the three years, a NATO source said.

A larger Afghan force would give the United States greater flexibility as it withdraws its troops, said Panetta, but he added Obama had yet to make a decision on the matter.
