New low-cost, transparent electrodes

June 27, 2013 ? Indium tin oxide (ITO) has become a standard material in light-emitting diodes, flat panel plasma displays, electronic ink and other applications because of its high performance, moisture resistance, and capacity for being finely etched. But indium is also rare and expensive, and it requires a costly deposition process to make opto-electronic devices and makes for a brittle electrode. Replacing indium as the default material in transparent electrodes is a high priority for the electronics industry.

Now, in a paper appearing in APL Materials, a new open-access journal produced by AIP Publishing, researchers report creating a sturdy, transparent, and indium-free electrode from silver (Ag) and titanium dioxide (TiO2) that could replace indium-based electrodes in some applications.

"Silver and titanium are much more abundant than indium in the earth's crust, and so we anticipate that electronic devices based on silver and titanium dioxide would be a more sustainable materials system and be manufactured at a low cost," said T.L. Alford, a professor of Materials Science and Engineering at Arizona State University who led the research.

The TiO2/Ag/TiO2 composite electrode multilayer film the researchers studied has been well characterized in the literature, but the team optimized both the thickness of the silver layer and the manufacturing process so that the multilayer film has a low sheet resistance and high optical transmittance, both properties necessary for high-performance.

The researchers created films with a sheet resistance as low as one sixth of that achieved by previous studies, while maintaining approximately 90 percent optical transmittance. With the choice of an underlying substrate made of polyethylene napthalate (PEN) -- a sturdy polymer used in a variety of applications from bottling carbonated beverages to manufacturing flexible electronics -- the researchers added additional durability.

Because of a less expensive manufacturing process and the wide availability of titanium dioxide, silver and PEN, the new TiO2/Ag/TiO2 thin film could one day help make devices such as electronic displays and solar cells more affordable by replacing more expensive indium-based electrodes.

Facebook removes ads from pages with offensive content

In move to appease marketers, Facebook will no longer show ads with offensive content.?

By Alexei Oreskovic,?Reuters / June 28, 2013

Advertising makes up 85 precent of revenue at Facebook, the world's largest social network with 1.1 billion users.

Facebook said it will no longer allow ads to appear on pages with sexual or violent content, as the online social network moves to appease marketers being associated with objectionable material.

'; } else if (google_ads.length > 1) { ad_unit += ''; } } document.getElementById("ad_unit").innerHTML += ad_unit; google_adnum += google_ads.length; return; } var google_adnum = 0; google_ad_client = "pub-6743622525202572"; google_ad_output = 'js'; google_max_num_ads = '1'; google_feedback = "on"; google_ad_type = "text"; // google_adtest = "on"; google_image_size = '230x105'; google_skip = '0'; // -->

The moves come a month after several businesses pulled their ads from Facebook?amid reports of pages on Facebook?that promoted violence against women.

Facebook?said at the time that it needed to improve its system for flagging and removing content that violated its community standards, which forbid users from posting content about hate-speech, threats and pornography, among other things.

Ads account for roughly 85 percent of revenue at Facebook, the world's largest social network with 1.1 billion users.?Facebook?said the changes would not have a meaningful impact on its business.

On Friday,?Facebook?said it also needed to do more to prevent situations in which ads are displayed alongside material that may not run afoul of its community standards but are deemed controversial nonetheless.

A?Facebook?page for a business that sells adult products, for example, will no longer feature ads. Previously such a page could feature ads along the right-hand side of the page so long as the page did not violate?Facebook's prohibition on depicting nudity.

The move underscores the delicate balance for social media companies, which features a variety of unpredictable and sometimes unsavory content shared by users, but which rely on advertising to underpin their business.

"Our goal is to both preserve the freedoms of sharing on Facebook?but also protect people and brands from certain types of content,"?Facebook?said in a post on its website on Friday.

Facebook?said on Friday that it would expand the scope of pages and groups on its website that should be ad-restricted and promised to remove ads from the flagged areas of the website by the end of the coming week.

Pages and groups that reference violence will also be off limits to ads, the company said. A Facebook?spokeswoman noted that the policy would not apply to the pages of news organizations on?Facebook.

Facebook?said the process of flagging objectionable pages and removing ads would initially be done manually, but that the company will build an automated system to do the job in the coming weeks.

Spiral galaxies like Milky Way bigger than thought

June 27, 2013 ? Let's all fist bump: Spiral galaxies like our own Milky Way appear to be much larger and more massive than previously believed, according to a new University of Colorado Boulder study by researchers using the Hubble Space Telescope.

CU-Boulder Professor John Stocke, study leader, said new observations with Hubble's $70 million Cosmic Origins Spectrograph, or COS, designed by CU-Boulder show that normal spiral galaxies are surrounded by halos of gas that can extend to over 1 million light-years in diameter. The current estimated diameter of the Milky Way, for example, is about 100,000 light-years. One light-year is roughly 6 trillion miles.

The material for galaxy halos detected by the CU-Boulder team originally was ejected from galaxies by exploding stars known as supernovae, a product of the star formation process, said Stocke of CU-Boulder's astrophysical and planetary sciences department. "This gas is stored and then recycled through an extended galaxy halo, falling back onto the galaxies to reinvigorate a new generation of star formation," he said. "In many ways this is the 'missing link' in galaxy evolution that we need to understand in detail in order to have a complete picture of the process."

Stocke gave a presentation on the research June 27 at the University of Edinburgh's Higgs Centre for Theoretical Physics in Scotland at a conference titled "Intergalactic Interactions." The CU-Boulder research team also included professors Michael Shull and James Green and research associates Brian Keeney, Charles Danforth, David Syphers and Cynthia Froning, as well as University of Wisconsin-Madison Professor Blair Savage.

Building on earlier studies identifying oxygen-rich gas clouds around spiral galaxies by scientists at the Space Telescope Science Institute in Baltimore, the University of Massachusetts, Amherst College and the University of California, Santa Cruz, Stocke and his colleagues determined that such clouds contain almost as much mass as all the stars in their respective galaxies. "This was a big surprise," said Stocke. "The new findings have significant consequences for how spiral galaxies change over time."

In addition, the CU-Boulder team discovered giant reservoirs of gas estimated to be millions of degrees Fahrenheit that were enshrouding the spiral galaxies and halos under study. The halos of the spiral galaxies were relatively cool by comparison -- just tens of thousands of degrees -- said Stocke, also a member of CU-Boulder's Center for Astrophysics and Space Astronomy, or CASA.

Shull, a professor in CU-Boulder's astrophysical and planetary sciences department and a member of CASA, emphasized that the study of such "circumgalactic" gas is in its infancy. "But given the expected lifetime of COS on Hubble, perhaps another five years, it should be possible to confirm these early detections, elaborate on the results and scan other spiral galaxies in the universe," he said.

Prior to the installation of COS on Hubble during NASA's final servicing mission in May 2009, theoretical studies showed that spiral galaxies should possess about five times more gas than was being detected by astronomers. The new observations with the extremely sensitive COS are now much more in line with the theories, said Stocke.

The CU-Boulder team used distant quasars -- the swirling centers of supermassive black holes -- as "flashlights" to track ultraviolet light as it passed through the extended gas haloes of foreground galaxies, said Stocke. The light absorbed by the gas was broken down by the spectrograph, much like a prism does, into characteristic color "fingerprints" that revealed temperatures, densities, velocities, distances and chemical compositions of the gas clouds.

"This gas is way too diffuse to allow its detection by direct imaging, so spectroscopy is the way to go," said Stocke. CU-Boulder's Green led the design team for COS, which was built by Ball Aerospace & Technologies Corp. of Boulder for NASA.

While astronomers hope the Hubble Space Telescope keeps on chugging for years to come, there will be no more servicing missions. And the James Webb Space Telescope, touted to be Hubble's successor beginning in late 2018, has no UV light-gathering capabilities, which will prevent astronomers from undertaking studies like those done with COS, said Green.

"Once Hubble ceases to function, we will lose the capability to study galaxy halos for perhaps a full generation of astronomers," said Stocke. "But for now, we are fortunate to have both Hubble and its Cosmic Origins Spectrograph to help us answer some of the most pressing issues in cosmology."

Economic well-being of children slips, report says

Economy

June 24, 2013 at 7:54 AM ET

This June 20, 2013 image shows David Hutchinson and his daughter Navaeh posing for a photograph at Joy Junction homeless shelter in Albuquerque, N.M.

Susan Montoya Bryan / AP

This June 20, 2013 image shows David Hutchinson and his daughter Navaeh posing for a photograph at Joy Junction homeless shelter in Albuquerque, N.M.

It wasn't so long ago that David Hutchinson spent a month sleeping under a bridge while his wife and young daughter spent their nights at a domestic violence shelter.

But this wasn't a case of domestic violence. The couple simply had no choice. There were just no shelters in Phoenix with room for another homeless family, and their top priority was finding a safe place for their daughter.

The family is one of many in the U.S. that have been trying to raise children in the face of joblessness and homelessness. An annual survey released Monday by the Annie E. Casey Foundation shows the number of children living in poverty increased to 23 percent in 2011, after the recession.

The Southwest has been hit particularly hard. New Mexico, for the first time, has slipped to worst in the nation when it comes to child well-being. More than 30 percent of children in the state were living in poverty in 2011 and nearly two-fifths had parents who lacked secure employment, according to this year's Kids Count survey.

Nevada is ranked No. 48, followed by Arizona. Mississippi, which has traditionally held last place, made slight improvements in early childhood education while reading and math proficiency for some students increased, putting the state at No. 49.

Overall, the report shows there have been gains in education and health nationally, but since 2005, there have been serious setbacks when it comes to the economic well-being of children.

"There's little doubt that things are getting worse," said Kim Posich, executive director of the New Mexico Center on Law and Poverty. "Aside from the fact the New Mexico economy has been so slow to turn around, the systems that generally serve people who are the working poor and suddenly lose their jobs or face greater hardship, all those systems have been strained beyond the max."

In Arizona, charities and government programs were cut during the recession, making it more difficult for families to get by and rebuild, said Dana Wolfe Naimark of the Children's Action Alliance in Phoenix.

"So many things were slashed just when people needed it the most," she said. "That is a key policy issue that we do have choices over. We can find ways to rebuild that investment. It's not OK to just throw up our hands and say, 'We can't.'"

According to the Kids Count report, a lingering concern is the effect of unemployment on children, particularly long-term unemployment. Researchers found that more than 4 million workers were unemployed for more than six months, and more than 3 million were without work for a year or more.

David Hutchinson and his family eventually ended up in Albuquerque. He has been looking for work for months. Finally, he landed a job just this week with a contractor who installs fire suppression systems.

"If I wasn't so crippled, I'd be doing backflips," he said, pointing to the rod and pins in his forearm, an injury that ended his career in the U.S. Navy.

His wife, Chelsea, said she knows her husband is ready to put aside any pain because the prospect of their family being able to move from Joy Junction, the shelter where they have been staying since December, hinges on a regular income.

William and Elimar Roper are in the same boat. They and their four children have been at the shelter for about a year. William just landed a job in the kitchen and Elimar has graduated from the shelter's recovery program, which helps those addicted to drugs or alcohol.

"We're happy because we've upgraded from being homeless to something that can help us stabilize. It's the first step," Elimar Roper said.

William Roper served in the U.S. Army for nine years and did tours in Iraq and Afghanistan. After the military, he worked as a janitor and then lost his job. The family's savings soon ran out, leaving them homeless.

The Kids Count report shows the percentage of children whose parents don't have secure employment has been increasing. That's more than one-third of children in each of the four states at the bottom of the Kids Count list.

"Growing up in poverty, it just has these terrible repercussions and you see these associations with much lower rates of high school graduation, lower performance overall in school, much lower rates of college attendance and the cycle perpetuates," said Curtis Skinner, director of Family Economic Security at the National Center for Children in Poverty.

Skinner said the center's research is showing a troubling trend in the aftermath of the recession: Poverty rates are rising in what used to be the middle class, in two-parent households and in families where parents have college educations.

While there is a lag in the Kids Count data, officials in New Mexico, Arizona and Nevada believe some of their numbers will start to turn around in the coming years thanks to investments in education, particularly pre-kindergarten programs.

New Mexico Gov. Susana Martinez has pushed for doubling pre-K funding and funneling more money to early literacy and high school graduation efforts.

"Clearly, doing things the way they've always been done hasn't worked for our kids," said Enrique Knell, a spokesman for the governor. "And reform efforts must include ending the practice of setting our children up for failure by passing them on to the next grade level when they can't read."

The well-being of their children has been the motivating factor for both the Hutchinson and Roper families. They want something better for their kids, and they say things are starting to turn around.

"Finally, being to the point of stabilizing and being able to get the kids out of this environment, that's a good feeling," Elimar Roper said.

U.S. regulator tells Web search firms to label ads better

By Alexei Oreskovic

SAN FRANCISCO (Reuters) - U.S. regulators warned leading Internet firms including Google Inc. to better identify paid ads in search results, particularly as new technology such as mobile services and voice-based online services become more common.

The U.S. Federal Trade Commission said on Tuesday it had sent letters to 24 Internet search companies, including giants Google, Microsoft Corp and Yahoo Inc, updating its guidance on advertising practices.

The FTC's update to its 2002 guidance on search advertising practices comes as consumers are increasingly accessing the Internet on small-screened smartphones and using specialized apps and social media services to find information online.

"In recent years, paid search results have become less distinguishable as advertising, and the FTC is urging the search industry to make sure the distinction is clear," the agency said.

The FTC, which sent the letters on Monday, has the power to fine companies that violate its rules against deceptive advertising.

The agency said background shading for search ads that appear alongside natural search results was not always sufficiently visible, particularly on mobile devices.

Text labels intended to flag search ads were not always easy to spot, as some search engines had reduced the font size of the text or placed a single label at the corner of a group of ads.

In the case of voice-based search for instance, the agency said that a search engine should make an "audio disclosure that is of an adequate volume and cadence for ordinary listeners to hear and comprehend it."

The letters, which were also sent to several popular "vertical" search engines that specialize in online shopping, travel and local business, did not specifically accuse any search engines of wrongdoing.

Google, the world's No.1 search engine, accounted for 73.8 percent of the $17.3 billion spent on search advertising in the United States last year, according to research firm eMarketer. Last year Google altered its specialized shopping search engine, making it based solely on paid search listings.

Google said in a statement that clear labeling and disclosure of paid search were important and "we've always strived to do that as our products have evolved."

Yahoo, which had 6.6 percent share of the U.S. online search ad market in 2012 according to eMarketer, said it was reviewing the letter and stressed its commitment to a transparent search experience.

Microsoft, the No.3. online search advertising company in the United States, declined to comment.

Democracy can't survive without strong political parties ?Sambo

By Taye Obateru & Hope Ofobike

Jos?Vice President, Namadi Sambo, yesterday, declared that democracy cannot survive without strong political parties.

He stated this at the commissioning of the Political Party Leadership and Development Centre of the National Institute for Policy and Strategic Studies, NIPPS, Kuru, Plateau State.

Represented by the Special Adviser, Political Matters in his office, Senator Isaiah Balat, Sambo said, although the tendency has been to pay more attention to governmental bodies and civic institutions, political parties actually oil the democratic wheel.

Sambo said: ?More concern is often shown to the establishment of governmental bodies and civic organisation, while little attention is paid to the development of strong political parties. Although both of the civil societies and other government bodies are important in every nation but without strong and dynamic political parties democracy cannot survive in the long run.?

?Political parties may decline overtime if they do not make conscious efforts to strengthen themselves. Leaders of the parties owe themselves the obligation to take advantage of opportunities offered by this centre for self-improvement.

?Leadership is developed through a never ending process of self study, education, training and experience to inspire us. As tomorrow?s leaders there are certain things we must be, know and do. These do not come naturally but are rather acquired through continuous work and training.?

He said, although politics, politicians and political parties are negatively viewed by the public, politics still remain a noble pursuit as it is about serving the public and improving the lives of citizens.

He restated the commitment of the Jonathan?s administration to the cause of free, fair and credible elections, adding that the establishment of the centre is an opportunity to raise the capacity of political parties to play their own role in achieving and sustaining the objective.

How Zombie Phones Could Create a Gigantic, Mobile Botnet

You've heard of the "botnet"?a collection of enslaved, malware-infested computers that act together to pump out spam and DDoS attacks, often unbeknownst to their owners. For the past decade, botnets have mostly been a problem for the PC world. But, according to a new report on mobile malware, it may not be long before we start seeing botnets built out of an increasingly sophisticated type of device: cell phones.

"It's only a matter of time before that's pervasive," said Karim Toubba, a vice president at Juniper Networks, the publisher of the study.

Google's Android operating system is by far the most vulnerable to outside attackers. Unlike Apple, which forces its iPhone apps through an infamously strict approval process before storing them in a single app store, Android phones are capable of downloading and installing apps from third-party websites.

As with Web browsing, visiting random sites and downloading software whose credentials you can't verify is a recipe for disaster. Yet many of us do it, even without realizing it. Ninety-two percent of the attacks detected by Juniper's mobile security research team last year took place on Android. The remaining 8 percent targeted smaller platforms like Windows Mobile, BlackBerry, and Symbian.

It's not just malicious apps?or bugs in legitimate apps?that let attackers get through. Mobile operating systems themselves have vulnerabilities. Hackers sometimes will disguise a piece of malware as a valid system update. Once it's installed, the malware can run in the background, monitor a user's behavior, and report that activity to a central command-and-control machine.

From there, it's not a huge jump to turn a compromised device into a slave. We already know it's possible, because it happens all the time to desktops and laptops.?

"The capabilities there are very similar," said Toubba, "to the underlying capabilities of the desktop operating system Linux."?

Android could neutralize the vast majority of malware threats out there, the Juniper report said, if it made sure every one of its devices were running the latest version of the operating system. The problem is, even after Google makes updates to Android, the burden is on your wireless carrier to actually push the update to your phone. And they aren't doing it. More than a third of all Android devices haven't been updated since February 2011. More than a quarter of Android devices haven't been updated since Dec. 2011.?

When I asked Toubba whether carriers needed to do a better job of updating their customers' phones, he said simply that many were "taking these risks and these threats quite seriously."

People with a disability more likely to be obese, have chronic illnesses

June 26, 2013 ? Adults with a disability are more likely to be obese or extremely obese than those without a disability according to a study led by researchers at The University of Texas School of Public Health, which is part of The University of Texas Health Science Center at Houston (UTHealth).

There are approximately 54 million Americans living with a disability and according to the latest research, nearly 42 percent of American adults with a disability were reported as obese and 9 percent as extremely obese. Participants were identified as having a disability if they reported mobility issues.

The findings are from a recent study published in the June edition of the American Journal of Preventative Medicine. The study is believed to be the first to assess the obesity prevalence of people with a disability based on measured height and weight rather than relying on participants to provide this information.

"Prior to this research, national samples only indicated obesity prevalence in adults with disabilities at 29 to 31 percent," said Katherine Froehlich-Grobe, Ph.D., lead author of the paper and associate professor of health promotion and behavioral science at The UT School of Public Health Dallas Regional Campus. "We were surprised at the magnitude of how high obesity prevalence was among those with a disability."

According to the study, adults with a disability had a higher prevalence of several chronic illnesses including diabetes, hypertension and high cholesterol. People with disabilities were twice as likely to have prescribed medication for hypertension and lipid-lowering medicine.

Froehlich-Grobe says the obesity disparity between people with disabilities and people without a disability should be addressed. She suggests that primary care providers should amp up their efforts on counseling patients to change their lifestyle with diet and exercise instead of only prescribing medication to control the chronic illnesses.

"Health care providers face a challenge when it comes to helping their patients with a disability manage their weight when exercise and physical activity play such an important role in weight management," said Froehlich-Grobe. "People with disabilities are under served by national efforts aiming at reducing and preventing obesity. We must focus on managing and reducing weight for individuals with a disability."

Recent guidelines say those with disabilities should participate in moderate physical activity and be as active as they can within the limitations of their disability. For more information on how people with a disability can become more active, visit The National Center on Health, Physical Activity and Disability's website.

Mexico breaks silence on US immigration bill: 'Walls aren't the solution'

US lawmakers are considering extending the border fence as part of the added security measures that would accompany plans to provide legal status to more than 11 million immigrants, the majority of them Mexican.

Foreign Minister Jos? Antonio Meade said the legislation would benefit Mexico?s countrymen in the US. But he also warned that the proposed fence extension could impact commerce, and the enormous legal flow of products and people across the border each day.

?Walls aren?t the solution to the migratory phenomenon, and they aren?t congruent with a modern and secure border,? he told media on Tuesday. ?They don?t contribute to the development of the competitive region that both countries want to encourage.?

Seventy percent of bilateral commerce happens over the border via trucks, and it?s worth $1 million per minute, Mr. Meade said. More than 1 million people cross the US-Mexico border legally every day.

Mexico has been publicly quiet in recent years on the US debate over immigration reform after former President Vicente Fox's vocal push for US reform appeared to some to be an overreach. He made specific demands, including wanting to see reform by "year end." That was in early September 2001, days before the 9/11 terrorist attacks that would set the country on a new course and see immigration reform fall by the wayside.

During the current US debate, the Mexican government has kept mum ??at least publicly ??on the legislation, saying the debate is an internal domestic issue. But Meade said that Mexico has sustained a ?permanent dialogue? with everyone involved since lawmakers began crafting the bill.

?Our country has let the United States government know that measures that could affect links between [border] communities detract from the principles of shared responsibility and neighborliness that both nations agreed upon.?

On the issue of shared responsibility: Over the past year, Mexico has found itself in the uncomfortable position of deterring increased illegal immigration through its own territory.

Illegal immigration between Mexico and the US fell to net zero last year, meaning that the number of crossers and returnees roughly canceled each other. However, in Texas? Rio Grande Valley, US authorities saw an increase in apprehensions of migrants ??the vast majority from Honduras, Guatemala, and El Salvador, according to a report by the Washington Office on Latin America. Mexico recently announced that Marines would take over securing its southern border.

As the US debate over the Border Security, Economic Opportunity and Immigration Modernization Act of 2013 gains steam, Meade noted Mexico?s requests are rooted in its desire for stronger economic development. These include the modernization of the infrastructure and administration of border ports of entry and measures that better facilitate the transit of products and people.

During last month?s meeting in Mexico, Presidents Enrique Pe?a Nieto and Barack Obama promoted the idea of a unified economic region saying they could better compete globally, together.

Fewer foreclosures, increased new home sales fueling housing market

WILMINGTON, NC (WWAY) -- Foreclosure rates are down and continue to fall in Wilmington. Meanwhile new home sales are up across the country.

Reports show foreclosure rates in our area in April 2012 were at 2.67 percent. Just one year later, the rate dropped to 1.72 percent.

"The tide is turning, and it is getting much better than it was a few years ago," realtor Michelle Clark said.

The rate of foreclosure in Wilmington is lower than the national rate of 2.65 percent. Real estate agents say this is because foreclosed properties are drying up.

"The opportunities that there were before are gone or going," Clark said. "I shouldn't say they're gone. There are still some foreclosures, there will always be foreclosures, but the steals, the opportunities, the abundance of them is gone."

Michelle Clark said this will help bring the real estate market back. For real estate agents, this is good news.

"It's actually shifting," realtor Joe Capellini said. "It's been a buyers market for years. It's actually shifting to being more of a sellers market."

And with new home sales up across the country, Capellini says good things are on the way for our city as well.

"When you start seeing more and more houses going up, that means the real estate market is healthy, the job market is growing, people have jobs, they want to buy houses, or certainly, they can stay in their houses, and you'll see fewer and fewer foreclosures," he said.

There's more good news on the housing front. The US Department of Commerce said today new home sales last month were at the highest level since July 2008.

New York City's New Subway Tunnel Looks Like a Level from Half-Life

New York City's Metro Transit Authority is still plugging away on its giant project to bring the the 7 train into far west Manhattan, and the scope of the construction is just as awe-inspiring as ever. The MTA just put out a crop of new pictures on Flickr, and we just can't help but see a slight comparison to a certain, classic Half-Life level of old.

The graphics are a lot better in real life, but you can't deny shades of "On a Rail" up in this. You know, with a few more cranes and a lot less houndeyes. And man, the anti-aliasing is to die for.

New York City's New Subway Tunnel Looks Like a Level from Half-Life

The work won't be finished until the summer of 2014, but in the meantime things look like they're coming along nicely. We're finally starting to see a subway, and not just a hole in the ground. Let's just hope they don't run into a Gargantua down there. [MTAPhotos]

Evernote Sharpens Up Its Picture-Annotating App Skitch For Mac

skitch_logoAfter a rough couple of months last year when users slammed Evernote for updates to image-annotation app Skitch that they believed were for the worse, today the company is releasing a new version of the Mac app. While the company is still taking slow steps for how it integrates Skitch into Evernote -- this was one of the bones of contention for legacy Skitch users in how the app was updated -- it is continuing to add more features like better drawing capabilities, part of Evernote's longer-term strategy to create productivity tools that draw more people to its platform and make Evernote an ever-more useful product.

New player is critical to unleashing T cells against disease

June 23, 2013 ? A major study from researchers at the La Jolla Institute for Allergy and Immunology provides new revelations about the intricate pathways involved in turning on T cells, the body's most important disease-fighting cells, and was published today in the scientific journal Nature.

The La Jolla Institute team is the first to prove that a certain type of protein, called septins, play a critical role in activating a calcium channel on the surface of the T cell. The channel is the portal through which calcium enters T cells from the blood stream, an action essential for the T cell's survival, activation, and ability to fight disease.

Patrick Hogan and Anjana Rao, Ph.D.s, are senior authors on the paper and Sonia Sharma and Ariel Quintana, Ph.D.s, are co-first authors. Drs. Sharma, Rao and Hogan are former researchers at Harvard Medical School with high-level genetics expertise who joined the La Jolla Institute in 2010. Dr. Quintana conducted advanced microscopy that was a major aspect of the study.

Dr. Hogan describes the discovery as another important step in understanding the overall functioning of T cells -- knowledge from which new, more precisely targeted drugs to treat diseases ranging from cancer to viral infections can emerge. "It's like working on an engine, you have to know what all the parts are doing to repair it," he says. "We want to understand the basic machinery inside a T cell. This will enable us to target the specific pressure points to turn up a T cell response against a tumor or virus or to turn it down in the case of autoimmune diseases."

The findings were published in a Nature paper entitled "An siRNA screen for NFAT activation identifies septins as coordinators of store-operated Ca2+ entry."

"We have found that the septin protein is a very strong regulator of the calcium response, which is essential for activating immune cells," says Dr. Sharma, who was recently appointed to a faculty position, and now leads her own independent laboratory at the La Jolla Institute, in addition to serving as scientific director of the newly established RNAi screening center.

Dr. Hogan says the discovery took the research team by surprise. "We knew septins existed in the cellular plasma (surface) membrane, but we didn't know they had anything to do with calcium signaling," he says. Septins are known to build scaffolding to provide structural support during cell division.

This finding builds on Dr. Rao and Dr. Hogan's groundbreaking discovery in 2006 showing that the protein ORAI1 forms the pore of the calcium channel. The channel's entryway had been one of the most sought after mysteries in biomedical science because it is the gateway to T cell functioning and, consequently, to better understanding how the body uses these cells to fight disease.

To the research team's surprise, the septins were forming a ring around the calcium channel. "We aren't sure why, but we theorize that the septins are rearranging the cellular membrane's structure to "corral" the key proteins STIM and ORAI1, and maybe other factors needed for the calcium channel to operate," says Dr. Hogan.

Dr. Sharma adds that, "essentially we believe the septins are choreographing the interaction of these two proteins that are important in instigating the immune response." Without the septins' involvement, T cell activation does not occur.

In the study, the researchers devised a simple visual readout of activity in a main pathway responsible for activation of T cells -- the same pathway that is targeted by the immunosuppressive drug cyclosporin A that is used clinically -- and looked for impairment of the activity when individual genes were, in effect, deleted. After sorting through the roughly 20,000 human genes, they turned up 887 gene "hits," says Dr. Hogan.

With further experiments, they should be able to classify those hits into genes that affect the calcium channel itself and genes that act later in the pathway. "We are hopeful that one or more of these genes can be used as a clinical target for new drugs to treat transplant rejection and immune diseases, some of the same indications now treated with cyclosporine A," adds Dr. Hogan. He believes that a medication aimed at an early step of calcium entry through the ORAI channel could be more effective and have fewer side effects than cyclosporin A, which targets a later step in the pathway and can cause complications such as kidney disease.

Snowden not on flight to Cuba, whereabouts unclear

MOSCOW (AP) ? A plane took off from Moscow on Monday headed for Cuba, but the seat booked by National Security Agency leaker Edward Snowden was empty, and there was no sign of him elsewhere on board. His whereabouts were unknown.

An Aeroflot representative who wouldn't give her name told The Associated Press that Snowden wasn't on flight SU150 to Havana. AP reporters on the flight couldn't see him.

Security around the aircraft was heavy prior to boarding and guards tried to prevent photographers and cameramen from taking pictures of the plane, heightening the speculation that he might have been secretly escorted on board.

The Interfax news agency, which has extensive contacts with Russian security agencies, cited a source as saying that Snowden could have flown out in a different plane unseen by journalists. Others speculated that Russian security agencies might want to keep Snowden in Russia for a more thorough debriefing.

Aeroflot said earlier that Snowden had registered for the flight using his American passport, which the United States recently annulled.

Snowden has not been seen since he arrived in Moscow on Sunday from Hong Kong, where he had been hiding for several weeks to evade U.S. justice. Ecuador is considering Snowden's asylum application.

After spending a night in Moscow's Sheremetyevo Airport, the former National Security Agency contractor ? and admitted leaker of state secrets ? had been expected to fly to Cuba and Venezuela en route to possible asylum in Ecuador.

Snowden, also a former CIA technician, fled Hong Kong to dodge U.S. efforts to extradite him on espionage charges. Ecuador's Foreign Minister Ricardo Patino said his government had received an asylum request, adding Monday that the decision "has to do with freedom of expression and with the security of citizens around the world." The anti-secrecy group WikiLeaks also said it would help Snowden.

Ecuador has rejected the United States' previous efforts at cooperation, and has been helping WikiLeaks founder Julian Assange avoid prosecution by allowing him to stay at its embassy in London.

Snowden gave documents to The Guardian and The Washington Post newspapers disclosing U.S. surveillance programs that collect vast amounts of phone records and online data in the name of foreign intelligence, often sweeping up information on American citizens. Officials have the ability to collect phone and Internet information broadly but need a warrant to examine specific cases where they believe terrorism is involved.

Snowden had been in hiding for several weeks in Hong Kong, a former British colony with a high degree of autonomy from mainland China. The United States formally sought Snowden's extradition from Hong Kong to face espionage charges but was rebuffed; Hong Kong officials said the U.S. request did not fully comply with their laws.

The Justice Department rejected that claim, saying its request met all of the requirements of the extradition treaty between the U.S. and Hong Kong. During conversations last week, including a phone call Wednesday between Attorney General Eric Holder and Hong Kong Secretary for Justice Rimsky Yuen, Hong Kong officials never raised any issues regarding sufficiency of the U.S. request, a Justice representative said.

The United States was in touch through diplomatic and law enforcement channels with countries that Snowden could travel through or to, reminding them that Snowden is wanted on criminal charges and reiterating Washington's position that Snowden should only be permitted to travel back to the U.S., a State Department official said.

U.S. officials spoke on condition of anonymity because they were not authorized to publicly discuss the case.

Caitlin Hayden, a spokeswoman for the National Security Council, said, "Given our intensified cooperation after the Boston marathon bombings and our history of working with Russia on law enforcement matters ? including returning numerous high-level criminals back to Russia at the request of the Russian government ? we expect the Russian government to look at all options available to expel Mr. Snowden back to the U.S. to face justice for the crimes with which he is charged."

Still, the United States is likely to have problems interrupting Snowden's passage. The United States does not have an extradition treaty with Russia, but does with Cuba, Venezuela and Ecuador. Even with an extradition agreement though, any country could give Snowden a political exemption.

The likelihood that any of these countries would stop Snowden from traveling on to Ecuador seemed remote. While diplomatic tensions have thawed in recent years, Cuba and the United States are hardly allies after a half-century of distrust.

Another country that could see Snowden pass through, Venezuela, could prove difficult, as well. Former President Hugo Chavez was a sworn enemy of the United States and his successor, Nicolas Maduro, earlier this year called President Barack Obama "grand chief of devils." The two countries do not exchange ambassadors.

It also wasn't clear Snowden was finished disclosing highly classified information.

Snowden has perhaps more than 200 sensitive documents, Sen. Dianne Feinstein, chairwoman of the Senate Intelligence Committee, said on CBS' "Face the Nation."

Unexpected discovery of the ways cells move could boost understanding of complex diseases

June 23, 2013 ? A new discovery about how cells move inside the body may provide scientists with crucial information about disease mechanisms such as the spread of cancer or the constriction of airways caused by asthma. Led by researchers at Harvard School of Public Health (HSPH) and the Institute for Bioengineering of Catalonia (IBEC), investigators found that epithelial cells -- the type that form a barrier between the inside and the outside of the body, such as skin cells -- move in a group, propelled by forces both from within and from nearby cells -- to fill any unfilled spaces they encounter.

The study appears June 23, 2013 in an advance online edition of Nature Materials.

"We were trying to understand the basic relationship between collective cellular motions and collective cellular forces, as might occur during cancer cell invasion, for example. But in doing so we stumbled onto a phenomenon that was totally unexpected," said senior author Jeffrey Fredberg, professor of bioengineering and physiology in the HSPH Department of Environmental Health and co-senior investigator of HSPH's Molecular and Integrative Cellular Dynamics lab.

Biologists, engineers, and physicists from HSPH and IBEC worked together to shed light on collective cellular motion because it plays a key role in functions such as wound healing, organ development, and tumor growth. Using a technique called monolayer stress microscopy -- which they invented themselves -- they measured the forces affecting a single layer of moving epithelial cells. They examined the cells' velocity and direction as well as traction -- how some cells either pull or push themselves and thus force collective movement.

As they expected, the researchers found that when an obstacle was placed in the path of an advancing cell layer -- in this case, a gel that provided no traction -- the cells moved around it, tightly hugging the sides of the gel as they passed. However, the researchers also found something surprising -- that the cells, in addition to moving forward, continued to pull themselves collectively back toward the gel, as if yearning to fill the unfilled space. The researchers dubbed this movement "kenotaxis," from the Greek words "keno" (vacuum) and "taxis" (arrangement), because it seemed the cells were attempting to fill a vacuum.

This new finding could help researchers better understand cell behavior -- and evaluate potential drugs to influence that behavior -- in a variety of complex diseases, such as cancer, asthma, cardiovascular disease, developmental abnormalities, and glaucoma. The finding could also help with tissue engineering and regenerative medicine, both of which rely on cell migration.

In carcinomas, for instance -- which represent 90% of all cancers and involve epithelial cells -- the new information on cell movement could improve understanding of how cancer cells migrate through the body. Asthma research could also get a boost, because scientists think migration of damaged epithelial cells in the lungs are involved in the airway narrowing caused by the disease.

"Kenotaxis is a property of the cellular collective, not the individual cell," said Jae Hun Kim, the study's first author. "It was amazing to us that the cellular collective can organize to pull itself systematically in one direction while moving systematically in an altogether different direction."

Lovefilm bringing Star Trek, other CBS shows to the UK and Germany

CBS may have teamed up with Netflix in the US to satisfy those of us with an Enterprising bent, but the company has taken a different tack in the UK and Germany. Instead, the firm has signed a deal with Lovefilm to bring CBS and Showtime-owned shows to Amazon's streaming network. The press release promises that users will be able to watch classic Star Trek, Voyager, The Good Wife, Dexter and Californication instantly, although a brief check of the UK site reveals that you may need to wait a short while more before you can immerse yourself in the Delta quadrant / Hank Moody's psyche.

Zimmerman portrayed as vigilante in Fla. shooting

SANFORD, Fla. (AP) ? George Zimmerman was fed up with "punks" getting away with crime and shot 17-year-old Trayvon Martin "because he wanted to," not because he had to, prosecutors argued Monday, while the neighborhood watch volunteer's attorney said the killing was self-defense against a young man who was slamming Zimmerman's head against the pavement.

The prosecution began opening statements in the long-awaited murder trial with shocking language, repeating obscenities Zimmerman uttered while talking to a police dispatcher moments before the deadly confrontation.

The defense opened with a knock-knock joke about the difficulty of picking a jury for a case that stirred nationwide debate over racial profiling, vigilantism and Florida's expansive laws on the use of deadly force.

"Knock. Knock," said defense attorney Don West.

"Who is there?"

"George Zimmerman."

"George Zimmerman who?"

"All right, good. You're on the jury."

Zimmerman, 29, could get life in prison if convicted of second-degree murder for gunning down Martin on Feb. 26, 2012, as the unarmed black teenager, wearing a hoodie on a dark, rainy night, walked from a convenience store through the gated townhouse community where he was staying.

The case took on racial dimensions after Martin's family claimed that Zimmerman had racially profiled Martin and that police were dragging their feet in bringing charges. Zimmerman, whose mother is Hispanic and whose father is white, has denied the confrontation had anything to do with race.

Prosecutor John Guy's first words to the jury recounted what Zimmerman told a dispatcher in a call shortly after spotting Martin: "F------ punks. These a-------. They always get away."

Zimmerman was profiling Martin as he followed him, Guy said. He said Zimmerman viewed the teen "as someone about to a commit a crime in his neighborhood."

"And he acted on it. That's why we're here," the prosecutor said.

Zimmerman didn't have to shoot Martin, Guy said. "He shot him for the worst of all reasons: because he wanted to," he said.

The prosecutor portrayed the watch captain as a vigilante, saying, "Zimmerman thought it was his right to rid his neighborhood of anyone who did not belong."

West told jurors a different story: Martin sucker-punched Zimmerman and then pounded the neighborhood watch volunteer's head against the concrete sidewalk, and that's when Zimmerman opened fire.

Showing the jury photos of a bloodied and bruised Zimmerman, the defense attorney said, "He had just taken tremendous blows to his face, tremendous blows to his head."

West said the story that Martin was unarmed is untrue: "Trayvon Martin armed himself with a concrete sidewalk and used it to smash George Zimmerman's head."

The prosecutor, however, disputed elements of Zimmerman's story, including his claim that Martin put his hands over Zimmerman's mouth and reached for the man's gun. Guy said none of Zimmerman's DNA was found on Martin's body, and none of the teenager's DNA was on the weapon or the holster.

But West said that doesn't prove anything, arguing that crime-scene technicians didn't properly protect Martin's hands from contamination.

Two police dispatch phone calls that could be important evidence for both sides were played for the jury by the defense. Martin's mother, Sybrina Fulton, left the courtroom before the second recording, which has the sound of the gunshot that killed Martin.

The first was a call Zimmerman made to a nonemergency police dispatcher, who told him he didn't need to be following Martin.

The second 911 call, from a witness, captures screams in the distant background from the struggle between Zimmerman and Martin. Martin's parents said the screams are from their son, while Zimmerman's father contends they are his son's.

Circuit Judge Debra Nelson ruled last weekend that audio experts for the prosecution won't be able to testify that the screams belong to Martin, saying the methods used were unreliable.

On Monday, one of the first witnesses for the prosecution was a custodian of police dispatch calls. During the witness' testimony, prosecutors started playing police calls Zimmerman had made in the months before he shot Martin. The defense objected, arguing the calls were irrelevant.

The judge said she would address the matter Tuesday and sent the jurors to the hotel where they are being sequestered for the duration of the trial, which could last several weeks

Other witnesses who testified Monday included a convenience store clerk and the 911 dispatcher who took Zimmerman's call when he was following Martin. Martin had gone to the convenience store to buy Skittles and a can of iced tea.

The 911 dispatcher, Sean Noffke, testified that he had advised Zimmerman not to follow Martin.

Randy McClean, a criminal defense attorney in Florida with no connection to the case, called the prosecution's opening statement "brilliant" in that it described Zimmerman's state of mind. But he described the knock-knock joke as less than stellar.

"If you're defending your client for second-degree murder, you probably shouldn't start your opening with a joke," McClean said.

One thing missing on Monday was visible demonstrations outside the courthouse.

Late Monday, the Seminole County NAACP held a town hall meeting at a church near a memorial site for Martin.

Martin family attorney Benjamin Crump, who as a potential witness in the case can't be present in the courtroom until he testifies, told the crowd that the outcome of the case would have far-reaching implications.

"It became a civil rights matter the night the police did not arrest the killer of an unarmed child," Crump said. "It's going to be a litmus test to show how far we have come."

    Icelandic Fin Whale Hunt Resumes, Stirs Debate

    Icelandic whalers angered environmentalists around the world this month by resuming their hunt for the endangered fin whale ? the second largest marine mammal after the blue whale. But the hunt may not threaten the population as terribly as some fear.

    Two of the 184 fin whales permitted by this summer's quota have hit port so far last week, according to the Icelandic Directorate of Fisheries. For many whale conservationists, that's two too many for a species that the International Union for the Conservation of Nature listed as endangered in 2010. The Natural Resources Defense Council has drafted a public petition urging the U.S. government to impose economic sanctions on Iceland in response to the hunt, and groups around the world have taken similar action. An online petition addressed to the Dutch government has gathered more than 1 million signatures this month.

    But Gisli Vikingsson, head whale researcher with Iceland's Marine Research Institute, argues the endangered species listing is misleading, and that this summer's hunt will not seriously threaten the mammal's vitality. Whereas the Southern Hemisphere fin whale population ? which once constituted 80 percent of the world's population ? suffered greatly from 20th-century commercial whaling and has failed to rebound, the North Atlantic population has grown in recent decades. [Images of Whales: Giants of the Deep]

    "There are several fin whale populations in the world, although it is all called one species," Vikingsson told LiveScience. "The sole reason for the poor status of this species is the Southern Hemisphere."

    Vikingsson estimates the central North Atlantic population could be as high as 25,000 individuals, based on a survey conducted in 2007. Given this population size, Vikingsson does not believe this summer's quota of up to 184 individuals will threaten the North Atlantic stock.

    "We have firm grounds to believe that there is an abundance, even using a precautionary approach," Vikingsson said.

    Iceland has defied the wishes of whale conservationists since 1986, when the government refused to abide by the International Whaling Commission's global moratorium on whaling. They did instate a ban on commercial whaling from 1989 through 2006, but continued hunting for research purposes.

    "Icelanders, we live from the resources of the sea," said Asta Einarsdottir, senior legal expert with the Icelandic Ministry of Fisheries. "So [whaling] is really part of our culture and tradition and our well-being."

    The majority of the fin whales caught are destined for Japan, where the market has strengthened since the 2011 Fukushima disaster. In fact, fin whale hunting was cancelled in 2011 and 2012, primarily due to the economic downturn in Japan after Fukushima, The Guardian reports.

    "This is done with much precaution, so we would never take the last whale," Einarsdottir told LiveScience. "It is of utmost importance to us."

    Even so, many others consider whale hunting a gruesome industry. "Much of the whale meat within Iceland is eaten by curious tourists rather than locals. Tourists mistakenly believe that whale meat is just another 'traditional' Icelandic dish but instead, are helping to keep this cruel industry alive," according to a statement this month by the Whale and Dolphin Conservation (WDC).

    The U.S. government also opposes commercial whaling. "We urge Iceland to honor the ban on commercial whaling and the international trade of whale meat," said Ryan Wulff, U.S. commissioner to the International Whaling Commission, according to the communications officer with the National Oceanic and Atmospheric Administration. "Iceland has developed a vibrant whale watching industry and is becoming quite an ecotourism destination, so it would be unfortunate if the decision to resume fin whaling had a detrimental effect on that momentum."

    'Supermoon' lights up night sky

    The night sky has been illuminated by what appears to be a much bigger and brighter Moon.

    The so-called "supermoon" occurs when the Moon reaches its closest point to earth, known as a perigee full moon.

    The effect makes the Moon seem 14% bigger and 30% brighter than when it is furthest from the planet.

    Skywatchers who miss the phenomenon this weekend because of cloudy skies will have to wait until August 2014 for the next one.

    Space expert Heather Couper said "supermoons" were the result of coincidence.

    "The Moon goes round in an oval orbit so it can come very close to us, and if that coincides with a full moon, then it can look absolutely enormous," she told BBC Radio 4's Today programme.

    She explained that when the Moon was high in the sky, it looked normal.

    But as it got closer to the horizon, a "kind of optical illusion" occurred where it looked bigger when compared with trees or houses, she said.

    She suggested it might be possible to dispel the illusion by turning away from the Moon, bending over and looking at the sky from between your legs.

    Writing in Sky and Telescope about the "myth of the supermoon", Shari Balouchi said much of what we called the supermoon was just our eyes playing tricks on us.

    "The supermoon might look bigger than normal if you see it in the evening when the Moon's just rising, but the real size difference isn't big enough to notice."

    BBC Weather's Darren Bett said he was confident most people in the UK would have been able to see the Moon at some point on Saturday night, even if only fleetingly.

    Sunday night should be better, he added, with people in south-west England and south Wales likely to have the clearest views of the Moon.

    However Marek Kukula, public astronomer at the Royal Observatory Greenwich, said people should not expect the supermoon to look that much bigger than normal.

    "It won't fill the sky," he said.

    "It's at its most impressive when the Moon is close to the horizon, ie when it's rising or setting - people will need to check online for rising and setting times for their locality."

    Dr Kukula said the US Naval Observatory and HM Nautical Almanac Office had online tools for checking the moon's rising and setting times.

    Scientists have dismissed the idea that the perigee can cause strange behaviour, like lycanthropy or natural disasters.

    Dr Couper said the tides this weekend would be unaffected.
