Report: Saudi Arabia may try to end anonymity for Twitter users

Saudi Arabia may try to end anonymity for Twitter users in the country by limiting access to the site to people who register their identification documents, the Arab News daily reported on Saturday.

Last week, local media reported the government had asked telecom companies to look at ways they could monitor, or block, free internet phone services such as Skype.

Twitter is highly popular with Saudis and has stirred broad debate on subjects ranging from religion to politics in a country where such public discussion had been considered at best unseemly and sometimes illegal.

Early this month, the security spokesman for Saudi Arabia's Interior Ministry described social networking, particularly Twitter, as a tool used by militants to stir social unrest.

The country's Grand Mufti, Saudi Arabia's top cleric, last week described users of the microblogging site as "clowns" wasting time with frivolous and even harmful discussions, local newspapers reported.

"A source at (the regulator) described the move as a natural result of the successful implementation of (its) decision to add a user's identification numbers while topping up mobile phone credit," Arab News reported.

That would not necessarily make a user's identity visible to other users of the site, but it would mean the Saudi government could monitor the tweets of individual Saudis.

The English-language daily and sister paper to the Saudi-owned pan-Arab Asharq al-Awsat newspaper did not explain how the authorities might be able to restrict ability to post on Twitter. Both newspapers belong to a publishing group owned by the ruling family and run by a son of Crown Prince Salman.

Internet service providers are legally obliged to block websites showing content deemed pornographic.

One of the big investors in Twitter is Saudi Arabian billionaire Prince Alwaleed bin Talal, a nephew of King Abdullah who also holds significant stakes in Citi Group, News Corp and Apple through his Kingdom Holding Company.

The country's telecom regulator, Communications and Information Technology Commission (CITC) did not immediately responded to requests for comment on the report. Last week it did not comment on the report it was seeking to restrict Skype use.

A spokeswoman for Kingdom Holding said Prince Alwaleed was not available to comment.

"There are people who misuse the social networking and try to send false information and false evaluation of the situation in the kingdom and the way the policemen in the kingdom are dealing with these situations," said Major General Mansour Turki, the security spokesman, at a news conference on Mar 8.

At a separate interview with Reuters this month, Turki argued that a small number of supporters of al Qaeda and activists from Saudi Arabia's Shi'ite minority used social media to stir wider sympathy for their goals and social unrest.

However, he also argued against banning the site.

Two weeks ago one of Saudi Arabia's most prominent clerics, Salman al-Awdah, who has 2.4 million followers on the site, used Twitter to attack the government's security policy as too harsh and call for better services. He warned it might otherwise face "the spark of violence".

Two leading Saudi human rights activists were sentenced to long prison terms this month for a variety of offences including "internet crimes" because they had used Twitter and other sites to attack the government.

Some top princes in the monarchy now use Twitter themselves and Crown Prince Salman, King Abdullah's designated heir and also Defence Minister, recently opened an official account.

U.S. says it takes North Korea threats seriously

WASHINGTON (Reuters) - The White House said on Saturday that it takes North Korea's latest saber-rattling threats seriously while cautioning that Pyongyang has a long history of bellicose rhetoric.

North Korea's latest bout of angry rhetoric included a vow that it is entering a "state of war" with South Korea a day after North Korean leader Kim Jong-un signed off on an order putting its missile units on standby to attack U.S. military bases in the South.

"We've seen reports of a new and unconstructive statement from North Korea. We take these threats seriously and remain in close contact with our South Korean allies," said Caitlin Hayden, spokeswoman for the White House National Security Council.

"But, we would also note that North Korea has a long history of bellicose rhetoric and threats and today's announcement follows that familiar pattern," she said.

The United States flew two nuclear-capable stealth bombers over the Korean peninsula as part of a military exercise this week in a show of force to reassure U.S. allies in the region.

The Pentagon has also been beefing up U.S. missile defense capabilities on the West Coast. The United States has been stressing that it has the capability and willingness to protect itself and U.S. allies in the region.

"We remain fully prepared and capable of defending and protecting the United States and our allies," said Hayden. "We continue to take additional measures against the North Korean threat, including our plan to increase the U.S. ground-based interceptors and early warning and tracking radar," and the recent signing of a South Korean-U.S. counter-provocation plan.

Eat Drink Better | Oklahoma Governor Signs Bill to Allow Horse ...

Neglected Horse

On Friday, Oklahoma governor Mary Fallin signed a bill to allow horse slaughter within the state.

House Bill 1999 prohibits the sale of horse meat for human consumption, but allows for the opening of horse slaughtering facilities in the state of Oklahoma. Forty-six other states already have laws allowing horse slaughter. Only Texas, California, and Illinois still have laws against horse slaughtering.

Horses in the U.S. are nearly always kept as pets, although there are some that work. Because they are not raised for meat, there are few limitations on the drugs that are given to the horses during their lives, even up to the moment of their deaths. Many of those drugs are dangerous for humans, rendering horse meat unfit for human consumption.

Currently, horses are purchased in the U.S. and shipped abroad for slaughtering. Supporters of horse slaughter in the U.S. claim that aging and unwanted horses will be abused if there are no slaughterhouses. In the statement from the governor?s office, Gov. Fallin said:

The U.S. Department of Agriculture has also noted that over 166,000 horses were sent to Canada and Mexico for processing just in 2012. These animals traveled long distances, in potentially inhumane circumstances, only to meet their end in foreign processing plants that do not face the same level of regulation or scrutiny that American plants would.

Simply making the slaughter of horses legal in the state doesn?t mean a slaughterhouse will open there any time soon. USDA meat inspectors have to be on the premises for slaughter to be legal. With the recent sequester, the beef industry has lost 8% of their inspection days. I doubt they will want to share the limited inspectors with an industry that isn?t even popular here in the U.S.

Son of pro wrestler Ric Flair found dead

(AP) ? Authorities say the son of professional wrestler Ric Flair has been found dead in a North Carolina hotel room.

Charlotte-Mecklenburg police says officers were called to a hotel on the city's south side around 10:30 a.m. Friday. When they arrived, they found the body of 25-year-old Reid Fliehr, who also was a wrestler.

A statement from police says there are no signs of foul play, and that the cause of death will be determined by the medical examiner's office.

Flair's agent released a statement Friday describing Reid as "an incredible son, brother, friend, and professional wrestler."

Ric Flair's real name is Richard Morgan Flair. The peroxide-blond wrestled for some 40 years and also was known as The Nature Boy.

The 64-year-old won many pro wrestling titles including in the WWE.

Picking apart photosynthesis: New insights could lead to better catalysts for water splitting

Mar. 28, 2013 ? Chemists at the California Institute of Technology (Caltech) and the Lawrence Berkeley National Laboratory believe they can now explain one of the remaining mysteries of photosynthesis, the chemical process by which plants convert sunlight into usable energy and generate the oxygen that we breathe. The finding suggests a new way of approaching the design of catalysts that drive the water-splitting reactions of artificial photosynthesis.

"If we want to make systems that can do artificial photosynthesis, it's important that we understand how the system found in nature functions," says Theodor Agapie, an assistant professor of chemistry at Caltech and principal investigator on a paper in the journal Nature Chemistry that describes the new results.

One of the key pieces of biological machinery that enables photosynthesis is a conglomeration of proteins and pigments known as photosystem II. Within that system lies a small cluster of atoms, called the oxygen-evolving complex, where water molecules are split and molecular oxygen is made. Although this oxygen-producing process has been studied extensively, the role that various parts of the cluster play has remained unclear.

The oxygen-evolving complex performs a reaction that requires the transfer of electrons, making it an example of what is known as a redox, or oxidation-reduction, reaction. The cluster can be described as a "mixed-metal cluster" because in addition to oxygen, it includes two types of metals -- one that is redox active, or capable of participating in the transfer of electrons (in this case, manganese), and one that is redox inactive (calcium).

"Since calcium is redox inactive, people have long wondered what role it might play in this cluster," Agapie says.

It has been difficult to solve that mystery in large part because the oxygen-evolving complex is just a cog in the much larger machine that is photosystem II; it is hard to study the smaller piece because there is so much going on with the whole. To get around this, Agapie's graduate student Emily Tsui prepared a series of compounds that are structurally related to the oxygen-evolving complex. She built upon an organic scaffold in a stepwise fashion, first adding three manganese centers and then attaching a fourth metal. By varying that fourth metal to be calcium and then different redox-inactive metals, such as strontium, sodium, yttrium, and zinc, Tsui was able to compare the effects of the metals on the chemical properties of the compound.

"When making mixed-metal clusters, researchers usually mix simple chemical precursors and hope the metals will self-assemble in desired structures," Tsui says. "That makes it hard to control the product. By preparing these clusters in a much more methodical way, we've been able to get just the right structures."

It turns out that the redox-inactive metals affect the way electrons are transferred in such systems. To make molecular oxygen, the manganese atoms must activate the oxygen atoms connected to the metals in the complex. In order to do that, the manganese atoms must first transfer away several electrons. Redox-inactive metals that tug more strongly on the electrons of the oxygen atoms make it more difficult for manganese to do this. But calcium does not draw electrons strongly toward itself. Therefore, it allows the manganese atoms to transfer away electrons and activate the oxygen atoms that go on to make molecular oxygen.

A number of the catalysts that are currently being developed to drive artificial photosynthesis are mixed-metal oxide catalysts. It has again been unclear what role the redox-inactive metals in these mixed catalysts play. The new findings suggest that the redox-inactive metals affect the way the electrons are transferred. "If you pick the right redox-inactive metal, you can tune the reduction potential to bring the reaction to the range where it is favorable," Agapie says. "That means we now have a more rational way of thinking about how to design these sorts of catalysts because we know how much the redox-inactive metal affects the redox chemistry."

The paper in Nature Chemistry is titled "Redox-inactive metals modulate the reduction potential in heterometallic manganese-oxido clusters." Along with Agapie and Tsui, Rosalie Tran and Junko Yano of the Lawrence Berkeley National Laboratory are also coauthors. The work was supported by the Searle Scholars Program, an NSF CAREER award, and the NSF Graduate Research Fellowship Program. X-ray spectroscopy work was supported by the NIH and the DOE Office of Basic Energy Sciences. Synchrotron facilities were provided by the Stanford Synchrotron Radiation Lightsource, operated by the DOE Office of Biological and Environmental Research.

How Do You Distract Yourself from the Agony of Exercise?

How Do You Distract Yourself from the Agony of Exercise?Exercise doesn't have to suck, but if you want to get into really great shape you have to work pretty hard and that's not fun or comfortable. Some people listen to music or podcasts to distract themselves. Others watch television, or even work. How do you distract yourself from the agony of exercise?

Not all exercise involves riding a stationary bike, running on a treadmill, and lifting weights, of course. Plenty of activities combine something fun with a workout. If that's how you enjoy your exercise, share that as well.

Be sure to submit the very same list of repairs and improvements to every single contractor with no modifications or additions. If you constantly alter the particulars, it will be really hard to find the best worth for your funds.

If a contractor delivers you a money discount, you want to decide on a distinct one particular. You aren?t going to have a paper trail if you pay with money you are not going to be in a position to do something if he does not full the function and will take your money.

Paint the walls of any space that is hunting tired and outdated. The overall look of any space can modify with a new coat of paint. It does not cost considerably to repaint your walls and doing so can boost your home?s worth. You?ll uncover that light, airy shades complement the widest range of different furnishings and decorating styles.

Consider the funds you commit now on insulation to be an investment in your extended term savings. Older houses typically look to want significantly more insulation. The addition of far more insulation in places of the house like the crawl space or attic could reduce your utility bills drastically.

Property owners really should do additions and renovations in the middle of a slump in the actual estate marketplace. You can typically save a lot of cash throughout these times, as numerous creating pros such as contractors are desperate for function. Home improvements in no way get old and expire. When you renovate your home for the duration of a slump, you save cash and your home?s worth will develop in the future.

Add a ceiling fan to your property. It?s simple and relatively low-cost to do this, so it is a excellent very first house improvement project. Ceiling fans can save you money by circulating the air in your house and creating air conditioning less required.

Give very good work to your home?s curb appeal. Attempt enhancing the outside of your house by having a nicely mowed lawn with trimmed edges. You may possibly also plant some nice shrubs.

Will Alabama Finally Let Its Citizens Brew Their Own Beer?

All around the country, homebrewers can proudly brag about their newest IPAs or chocolate porters. They can openly discuss their malts, their mash, and their wort. They can even pop into a local shop to pickup a bottling bucket or hydrometer. All around the country, that is, except in Alabama. But that may soon change.

Alabama is the last state in the country in which homebrewing is illegal. In fact, it?s illegal just to own the equipment to brew beer there. It?s a law that dates back to the end of prohibition, when states were given the right to issue their own laws governing the consumption and distribution of alcohol. But two bills?one in the state House of Representatives and the other in the state Senate? making it legal for individuals to make as much as 15 gallons of beer, wine, or hard cider every three months could pass as early as next week.

?Alabama is last again,? said Republican Bill Holtzclaw, the sponsor of the senate bill. ?When you try and think about reasons why the state doesn?t allow it, you just can?t come up with good answers.?

The popularity of craft beer and homebrewing has certainly been on the rise around the country. Just this past week, Mississippi became the 49th?state to legalize homebrewing, joining former holdout states like Utah and Oklahoma, which came on board within the last five years. Homebrewing became legal under federal law in 1978, and today The American Homebrewer?s Association estimates that there are now nearly one million people brewing beer or making wine in their homes at least once a year. Even the White House produced a Honey Ale last year.

But just because Bill?Holtzclaw?can?t think of points of opposition, that?doesn?t mean no one else can. Advocates who've been fighting for legalization since 2009 have been met?with sharp resistance from a religious group called the Alabama Citizen Action Program. Currently led by a Baptist pastor named Joe Godfrey, ALCAP has been fighting for temperance since it was founded in 1937.

Godfrey says there are a lot of issues at play here: children getting access to alcohol (?How will parents know if they take a swig from a gallon jug??); the policing of activities (?Nobody?s going to raid houses to make sure they aren?t making too much of it or selling it?); and the slippery slope argument (?Pretty soon you?re going to have a distiller say if you can make beer and wine, why not have a moonshine operation??).

Between ALCAP's opposition and the task of trying to pass alcohol legislation in a state with 26 counties that are at least partially dry, it?s been an uphill slog for homebrewers. In 2011, a House version of the bill failed so miserably it won the award for? ?deadest bill of the year.? There is an actual award for this. It comes in the shape of a coffin.

State Rep. Richard Laird told National Journal that he would not be supporting the bill this year because he is afraid that without enough oversight, underground connections between homebrewers and moonshiners could arise.

?If people start making and stockpiling beer, who?s to say the moonshiners wouldn?t come up and buy their supply and resell it,? he said.

Gary Glass, the Director of the American Homebrewers Association which has helped out on the bill, says it?s been the most difficult attempt at legalization he?s dealt with, including getting a bill through a mostly Mormon legislature in Utah. But this year, he believes the efforts will pay off.

?There used to be a perception that homebrewing and moonshining were the same thing,? Glass said. ?The perception has changed in the past years.?

While Laird, who is an independent in the state legislature, might not agree, it sounds as if Glass is right. Even Godfrey at ALCAP says he expects the bill to pass (?But not without me making them work for it?), and the governor has said he will sign it into law if it gets to his desk.

All this is music to Glass?s ears.

?Homebrewers should be able to operate in the open,? he said. ?And it?s not just about the hobby. This country has a unique beer culture, and many of these craft beers and new beer styles all start with someone making it in their home.?

Hybrid ribbons a gift for powerful batteries

Tuesday, March 26, 2013

Hybrid ribbons of vanadium oxide (VO2) and graphene may accelerate the development of high-power lithium-ion batteries suitable for electric cars and other demanding applications.

The Rice University lab of materials scientist Pulickel Ajayan determined that the well-studied material is a superior cathode for batteries that could supply both high energy density and significant power density. The research appears online this month in the American Chemical Society journal Nano Letters.

The ribbons created at Rice are thousands of times thinner than a sheet of paper, yet have potential that far outweighs current materials for their ability to charge and discharge very quickly. Cathodes built into half-cells for testing at Rice fully charged and discharged in 20 seconds and retained more than 90 percent of their initial capacity after more than 1,000 cycles.

"This is the direction battery research is going, not only for something with high energy density but also high power density," Ajayan said. "It's somewhere between a battery and a supercapacitor."

The ribbons also have the advantage of using relatively abundant and cheap materials. "This is done through a very simple hydrothermal process, and I think it would be easily scalable to large quantities," he said.

Ajayan said vanadium oxide has long been considered a material with great potential, and in fact vanadium pentoxide has been used in lithium-ion batteries for its special structure and high capacity. But oxides are slow to charge and discharge, due to their low electrical conductivity. The high-conductivity graphene lattice that is literally baked in solves that problem nicely, he said, by serving as a speedy conduit for electrons and channels for ions.

The atom-thin graphene sheets bound to the crystals take up very little bulk. In the best samples made at Rice, fully 84 percent of the cathode's weight was the lithium-slurping VO2, which held 204 milliamp hours of energy per gram. The researchers, led by Rice graduate student Yongji Gong and lead author Shubin Yang, said they believe that to be among the best overall performance ever seen for lithium-ion battery electrodes.

"One challenge to production was controlling the conditions for the co-synthesis of VO2 ribbons with graphene," Yang said. The process involved suspending graphene oxide nanosheets with powdered vanadium pentoxide (layered vanadium oxide, with two atoms of vanadium and five of oxygen) in water and heating it in an autoclave for hours. The vanadium pentoxide was completely reduced to VO2, which crystallized into ribbons, while the graphene oxide was reduced to graphene, Yang said. The ribbons, with a web-like coating of graphene, were only about 10 nanometers thick, up to 600 nanometers wide and tens of micrometers in length.

"These ribbons were the building blocks of the three-dimensional architecture," Yang said. "This unique structure was favorable for the ultrafast diffusion of both lithium ions and electrons during charge and discharge processes. It was the key to the achievement of excellent electrochemical performance."

In testing the new material, Yang and Gong found its capacity for lithium storage remained stable after 200 cycles even at high temperatures (167 degrees Fahrenheit) at which other cathodes commonly decay, even at low charge-discharge rates.

"We think this is real progress in the development of cathode materials for high-power lithium-ion batteries," Ajayan said, suggesting the ribbons' ability to be dispersed in a solvent might make them suitable as a component in the paintable batteries developed in his lab.

When Google Keep (free) launched earlier this week, some scratched their heads over the clean, simple service and wondered whether it could compete against the likes of Evernote. While the Keep Android app does what it's supposed to do, and does so stylishly, it has yet to prove its worth in an already crowded space.

Using Google Keep
After you fire up the app, Keep will ask you to select one of your saved Google accounts on your Android device, or enter a new one.

You'll immediately be taken to Keep's spare main page with a search bar across the top, a prompt to write a note underneath, and several icons indicating the kind of notes you can make. Simply typing in the text field and pressing Enter will create a text note (as does tapping the document icon). Tapping the check mark starts an itemized list. The microphone button begins recording a speech-to-text voice note, and the camera adds a picture note.

These aren't hard and fast categories, but more like shortcuts to start you off. Pictures can be added to any type of note, and text and photos added to voice notes. Lists can only be lists, and recordings cannot be added to any other type of note.

It's noteworthy (pun intended) that voice notes are only available in Keep's Android app. I found the voice-to-text transcription to be remarkably accurate, much more so than Google Voice. The recording option is probably the fastest way to add a note.

Though there is a settings menu, its primary function is to switch users.

Light on Organization
Notes can be moved to some degree within the app. Rearrange them by tapping and holding notes, and delete notes by dragging them to a trash can icon in the corner. Google Keep makes good use of gestures letting you "archive" a note with a swipe, moving it out of sight but keeping it searchable. The clean app also pops with animations as you move notes around.

There are no tags or notebooks to file notes in Keep, but you can color-code notes from a limited pallet. This is a bit odd, especially considering that Google's now defunct Notebook application once boasted these features. In her review of the Keep web interface, Jill Duffy noted that the color doesn't appear on a new note until after you completed it (and even then, it's just a thin bar of color at the top).?In the Android version, as soon as you select a color, it's applied to the whole note body.

Searching is the best way to find your notes, though the app lacks optical character recognition like Evernote, ?meaning it cannot read text in images. Notes appear the moment they have matches against the search term, and drop out as soon as they're not relevant. Oddly, there is no icon in the app for Google's voice search.

Wonderful Widgets
Widgets are rarely implemented well, but Google Keep does a good job. The app comes with three, two for the lockscreen and one for the desktop. The desktop widget is virtually identical to the more stripped-down lockscreen widget, which are simply shortcuts to creating different note types in the app.

The larger lockscreen widget lets you scroll through all your notes, as well as create new ones. Notably, creating new notes from any of the lockscreen widgets requires you to unlock your device.

It seems like a missed opportunity that the widgets don't allow recording voice notes directly from the lockscreen or desktop without going to the app. However, you can add a voice note from the Google Now widget by saying, "make a note for..."

It also would have been useful to assign certain notes to the lockscreen; being able to look at my grocery list and check off the items without opening the app would be a neat little time saver. Google is on the right track with the widgets, but would do well to expand their capabilities.

No App is an Island?Except Google Keep
The other elements of Google Drive?word processing, spreadsheets, etc.?used to be separate products but were seamlessly rolled up with file storage into one neat app. Keep, on the other hand is an appendage. Your Keep notes and images exist only in Keep, though it is somehow connected to Google Drive.

The isolation continues because although you can share your notes from Keep for Android, the recipient cannot collaborate with you on that note. If I share a note via email or Dropbox, the recipient just sees the note's contents.

The isolation also seems odd because it's difficult to grow your Keep notes into something larger. Grocery lists might not be useful later on, but the promo for Google Keep shows a musician building the elements of a rock show with the app. Actually pulling this off is difficult because items in Keep only become collaborative once you move them out of Keep. (Weirdly, one of the places to move Keep items is Google Drive.)

Also, though the Keep app makes use of Google's search technology, you have to be searching in Keep to find your note. That might seem fine, but if you can't remember where you saved that image (Drive? Keep? Gmail?) tracking it down will be tricky.

Is It a Keeper?
Google seems to have looked at all the other note taking options (and probably its own defunct offering) and decided they were all too complex and too busy?and there's something to be said for that. But the strength of Evernote is that it provided lots of options to be used however you like. Google's simplicity, while aesthetically pleasing, limits what you can do. Really, Google Keep is to Google Drive what Microsoft OneNote is to SkyDrive, only Keep isn't as universally accessible on different platforms.

If you just need a fast, easy way to make lists and add little tidbits to your digital hoard, then Keep can work for you. The app looks great, is easy to use, and Google has a strong track record for reliable data storage. It also means having one less login to remember.

That said, Keep has a lot of unused potential. If Google brings it into the fold, tying it closer to all the other Google products, we could have a real winner on our hands.

Spotify Plans To Take On Netflix And HBO With Streaming Video ...

Spotify, the on-demand music service, is planning a major change.

According to two sources briefed on the company's plans,?Spotify intends to become an on-demand music?and video service?? one that would invest in original content and compete heads-on with Netflix.

Ultimately, Spotify's metamorphosis would also put it into competition with?content creators and providers such as HBO.

Our sources said that Spotify is looking for partners that can help it fund and create exclusive content.?It is unclear if these talks would lead to a new round of investment in Spotify itself.

Spotify is already worth billions of dollars on paper thanks to several huge rounds of investment ? the last of which we started hearing about this time last year and later closed in the fall.?The $100 million investment from Coca-Cola and Goldman Sachs valued Spotify at $3 billion.

Spotify has become a very popular service with consumers, but its business remains challenged. The reason: extremely thin margins. Spotify does not own the music its customers listen to.?Music labels do, and Spotify has to pay the labels every time a customer listens to one of their songs.?As Spotify gets more popular, the labels charge more and more.

The original plan for Spotify was that it would grow so popular with music listeners that Spotify would be able to dictate negotiations with the labels.

This hasn't happened. This is in part because there are several Spotify competitors all bidding for the same rights to the same music. Even though it has become a significant source of revenue for the labels, Spotify still depends on the labels more than they depend on it.

How does becoming a video on-demand service like Netflix help solve this problem?

A year ago, Netflix was dealing with a similar challenge ? just in video instead of music.

Netflix did not own any of the content it streamed, and the Hollywood studios that did own the content were able to charge Netflix huge, margin-thinning amounts of money.

Then, in February, Netflix did something different.?

It made video content available through its service that it had not acquired from elsewhere ? an original series called House Of Cards.

The series was not cheap to produce. It costs ~$5 million per episode, and that doesn't include marketing expenses that put House Of Cards posters all over the country.

Netflix's gamble was that House Of Cards?would attract new subscribers to the service and that these people would remain subscribers even after viewing all 13 episodes.?

It hopes the multi-year revenues generated by those new long-term subscribers will more than pay for?House Of Cards'?substantial upfront cost.

It's entirely unclear as of yet whether or not Netflix's gamble will pay off.

But ? we have seen a similar plan work before.?

HBO used to be a cable channel best known for showing movies after they'd already been in the theater.

Then it started producing original content like The Sopranos and?Sex And The City.

Today, people pay $15-$20/month to subscribe to HBO for original programming like Girls and Game Of Thrones.?

Shows like those cost huge sums of money to create, but they attract subscribers who stay subscribers. Now HBO is the premier property in Time Warner's most profitable division.

Netflix and Spotify are betting that they can pull off a similar trick?as the distinction between Internet-based video and cable TV blurs thanks to the rise of smartphones, tablets and Internet-connected TVs and set-top boxes.

Briefed on the details of this story, Spotify declined to comment.

Cops: Anonymous tip sparked arrests in Georgia tot's slaying

Glynn County Detention Center/AP

De'Marquise Elkins, 17, is accused of fatally shooting a 13-month-old baby in the face and wounding his mother during their morning stroll in Brunswick, Ga.

BRUNSWICK, Ga. -- An anonymous tip led to?arrests in the shooting death of baby who was killed in a stroller, police said on Sunday.

The Brunswick Police Department said that they received a tip that someone was crouched in the back seat of a vehicle as it drove away from the shooting on Thursday.

The Glynn County detective's division spent hours following up on the tip and eventually arrested a 14-year-old suspect. The boy's statements led them to take 17-year-old De'Marquise Elkins into custody.

Elkins is charged with murder in the death of 13-month-old Antonio Santiago. The baby's mother, Sherry West, said she was walking home when Elkins and a younger boy approached and asked her for money.

Elkins' family says he did not shoot the baby.

'The Voice' Season 4: It's All About the (New) Judges

When the fourth season of The Voice arrives on Monday (8 p.m. ET on NBC), it will be without that outlandish diva and…that other outlandish diva. As you've probably heard by now, stars Christina Aguilera and Cee Lo Green are both taking a break to pursue other projects, and have ceded their spinning chairs to Latin pop superstar Shakira and that unstoppable R&B mainstay, Usher.

Three Fun and Simple Arts and Crafts Projects - Ledyard, CT Patch

?

Looking for some fun and easy arts and craft projects for the kids? Angela Antonelli of CreativeWorks for Children in Avon walks us through three simple craft ideas. Photos of the projects are posted above.

Pipe Cleaner Sculpture

Supplies: Styrofoam base, pipe cleaners, beads, buttons, feathers, etc.

Antonelli said that parents love this easy project for two reasons: it's glue free, and the kids can make as many changes to their sculptures as their little hearts desire!

"I hear back from parents that their kids are constantly changing and manipulating their projects," she said.

To build the sculpture, simply assemble the supplies, either from home or from the bargain bins at the craft stores, hand the kids a styrofoam block and let them "go to town," as Antonelli described it.

The materials are all either inserted into the block or threaded onto the pipe cleaners.

Colorful Tissue Paper Leaf

Supplies: Paper leaf, tissue paper, paint brush, water

This super easy craft is a fun project for kids as young as two years, Antonelli said.

To create the leaves, first either buy paper cut into a leaf shape or make your own. Just make sure that the paper is porous and without a finish.

Second, get the paint brush slightly wet and paint a layer of water on the leaf. Then tear up the tissue paper into little pieces and place them on the leaf.

"Mixing up the colors to create new ones is a neat lesson for the kids," Antonelli said.

Once the design is complete, paint the leaf with water one more time, and then put it in a safe place to dry. Antonelli said that most leaves will take about an hour to dry, depending on how "enthusiastic" the crafters were with the water.

Fairy Garden

Garden supplies: styrofoam base at least an inch and a half thick, potpourri, some fake (or real) leaves and flowers

Fairy supplies: pipe cleaners, fake flowers, embroidery floss, wooden bead with a hole in the middle, tacky glue

To create a magical fairy wonderland, Antonelli encourages families to look around the house for supplies. Packaging material can serve as a styrofoam base, and the materials from potpourri can be used to create the "forest."

Antonelli suggests using cinnamon sticks as the trunks of trees and little potpourri acorns or other fragments to populate the woodland ground.

While the cinnamon sticks, or sticks straight from nature, can be inserted into the styrofoam, kids should use the tacky glue (Antonelli recommends Aleene's) to attach the leaves, flowers, moss and other materials to the forest.

To create the fairies, cut two pieces of pipe cleaner, 3-4 inches long and another about 2 inches long.?

Fold over the longer piece and twist it in the middle. Separate the two lower pieces below the twist to create the legs. (See photo above).

Wrap the second, smaller pipe cleaner around the middle of the longer piece to make arms.

Thread the top of the pipe cleaner through the wooden bead. Antonelli said that the beads are available at craft stores, often with a face painted on them already. If not, kids can draw or paint a face on the bead beforehand.

Fold the tip of the pipe cleaner on the top of the bead, and glue it down. Wait for it to dry, then select some embroidery floss to glue onto the head for hair.

Separate the petals from a fake flower to create a skirt. Either thread the pipe cleaner legs through the hole at the center of the bloom, or glue the petals on.

Wings are created using individual petals or with other material like doilies or tissue paper.

Pope Francis meets with ambassadors from the 180 countries that have diplomatic relations with the Holy See at the Vatican, Friday, March 22, 2013. The Pontiff called Friday for more dialogue with Islam and offered an olive branch to China and other countries that don't have diplomatic relations with the Holy See. In his first foreign policy address as pope, Francis delivered his remarks in Italian rather than the traditional French ? another indication that the Argentine-born pope is less than comfortable speaking languages other than Italian and his mother-tongue Spanish. (AP Photo/Tony Gentile, Pool)

(AP) ? The two men in white embraced and showed one another the deference owed a pope in ways that surely turned Vatican protocol upside down: A reigning pope telling a retired one, "We are brothers," and insisting that they pray side-by-side during a date to discuss the future of the Catholic Church.

Pope Francis traveled Saturday from the Vatican to this hilltown south of Rome to have lunch with his predecessor, Benedict XVI, an historic and potentially problematic melding of the papacies that has never before confronted the church.

In a season of extraordinary moments, starting with Benedict's resignation and climaxing with the election of the first Latin American pope, Saturday's encounter provided perhaps the most enduring images of this papal transition as popes present and past embraced, prayed and broke bread together.

"It was a moment of great communion in the church," said the Vatican spokesman, the Rev. Federico Lombardi. "The spiritual union of these two people is truly a great gift and a promise of serenity for the church."

Benedict, 85, has been living at the papal retreat in Castel Gandolfo since he stepped down Feb. 28 and became the first pope to resign in 600 years. From the moment he was elected, Francis, 76, made clear he would go visit him, refusing in a way to let Benedict remain "hidden from the world" as he had intended.

Wearing a white quilted jacket over his white cassock to guard against the spring chill, Benedict greeted Francis on the helipad of the Castel Gandolfo gardens as soon as the papal helicopter landed. They embraced and clasped hands. And in a series of gestures that followed, Benedict made clear that he considered Francis to be pope while Francis made clear he considered his predecessor to be very much a revered brother and equal.

Traveling from the helipad to the palazzo, Benedict gave Francis the seat on the right-hand side of the car, the traditional place of the pope, while Benedict sat on the left. When they entered the chapel inside the palazzo to pray, Benedict tried to direct Francis to the papal kneeler in the front, but Francis refused.

Taking Benedict's hands and drawing him near, Francis said, "No, we are brothers," Lombardi said. The two used a longer kneeler in the pews and prayed side-by-side, the papal kneeler facing the altar left vacant.

It was a gesture that, 10 days into Francis' papacy, is becoming routine: a shunning of the trappings of the papacy in favor of a collegial and simple style that harks back to his Jesuit roots and ministry in the slums of Buenos Aires.

Francis also brought a gift for Benedict, an icon of the Madonna.

"They told me it's the Madonna of Humility," Francis told Benedict. "Let me say one thing: When they told me that, I immediately thought of you, at the many marvelous examples of humility and gentleness that you gave us during your pontificate."

Benedict replied: "Grazie, grazie."

Outside the villa, the main piazza of Castel Gandolfo was packed with well-wishers bearing photos of both popes and chanting "Francesco! Francesco!" But the crowd soon dissipated after Francis' helicopter left 2.5 hours later, without either pope coming to the balcony as many had hoped.

The Vatican downplayed the remarkable reunion in keeping with Benedict's desire to stay out of the spotlight so as not to interfere with his successor's papacy. There was no live coverage by Vatican television, and only a short video and still photos were released after the meeting. No details of the pair's private talks or lunch were released.

All of which led to enormous speculation about what these two men in white might have said to one another. That the former Cardinal Jorge Mario Bergoglio was second only to Cardinal Joseph Ratzinger in the 2005 conclave that elected Ratzinger pope ? considered then to be the "anti-Ratzinger" candidate ? only added to the popular imagination about what two men with such radically different styles, backgrounds and priorities might have chatted about over lunch.

Perhaps during their primo, or pasta course, they discussed the big issues facing the church: the rise of secularism in the world, the drop in priestly vocations in Europe, the competition that the Catholic Church faces in Latin America and Africa from evangelical Pentecostal movements.

During their secondo, or second course of meat or fish, they may have discussed more pressing issues about Francis' new job: Benedict left a host of unfinished business on Francis' plate, including the outcome of a top-secret investigation into the leaks of papal documents last year that exposed corruption and mismanagement in the Vatican administration. Francis might have wanted to sound Benedict out on his ideas for management changes in the Holy See administration, a priority given the dysfunctional government he has inherited.

Benedict's resignation ? and his choices about his future ? have raised the not-insignificant question of how the Catholic Church will deal with the novel situation of having one reigning and one retired pope living side-by-side.

Before Benedict announced his decision to be known as "emeritus pope" and "Your Holiness," one of the Vatican's leading canon lawyers, the Jesuit Rev. Gianfranco Ghirlanda, penned an article suggesting that such a title would be inappropriate for Benedict since in renouncing the papacy he had "lost all the power of primacy" conferred on him by his election. The Vatican had originally said Benedict would likely be known as "emeritus bishop of Rome" precisely to avoid confusion with the new pope.

But Benedict went ahead with the title and chose to keep wearing the white cassock of the papacy, albeit without the sash and cape worn by Francis, leading to questions about both his own influence on the future pontiff and whether Catholics more favorable to his traditional style might try to undermine his successor's authority and agenda by keeping their allegiance to the old pope.

Clearly aware of that potential, Benedict in his last meeting with his cardinals on Feb. 28 pledged his "unconditional reverence and obedience" to the then-unknown future pope, who was nevertheless in the room.

Lombardi said he understood Benedict had repeated that pledge of obedience to Francis on Saturday. Asked how the popes addressed one another, Lombardi demurred, saying he didn't think they addressed one another as "Your Holiness" or "Pope," saying the exchange was too familiar and warm for such titles.

The two men couldn't be more different in style and background: The Argentine-born Francis has made headlines with his simple gestures ? no papal regalia, simple black shoes, paying his own hotel bill ? and basic message that a pope's job is to protect the poor.

As archbishop of Buenos Aires, the man now known as Pope Francis worked in the slums, celebrating Masses for prostitutes and drug addicts. He plans to celebrate Holy Thursday Mass this week at a juvenile detention center, where he will wash the feet of 12 inmates in a show of humility echoing that of Jesus.

The German-born Benedict is an academic, one of the world's leading theologians who spent more than 30 years in the frescoed halls of the Vatican where he was first its chief doctrinal watchdog and then its pope. His primary concern was to remind Christians in Europe of their faith and bring back a more traditional Catholic identity, and with it the brocaded style of the papacy. His Holy Thursday Masses included the traditional foot-washing, but it involved clerics at the St. John Lateran basilica.

While there is a difference in style, there is a "radical" convergence in their spirituality, according to Civilta Cattolica, the Italian Jesuit magazine whose articles are approved by the Vatican before publication.

"They are two figures of the highest spirituality, whose relationship with life is completely anchored in God," the magazine wrote. "This radicalness is shown in Pope Benedict's shy and kind bearing, and in Pope Francis it is revealed by his immediate sweetness and spontaneity."
