Graphene/nanotube hybrid makes single-surface material for energy storage, electronics

ScienceDaily (Nov. 27, 2012) ? A seamless graphene/nanotube hybrid created at Rice University may be the best electrode interface material possible for many energy storage and electronics applications.

Led by Rice chemist James Tour, researchers have successfully grown forests of carbon nanotubes that rise quickly from sheets of graphene to astounding lengths of up to 120 microns, according to a paper published November 27 by Nature Communications. A house on an average plot with the same aspect ratio would rise into space.

That translates into a massive amount of surface area, the key factor in making things like energy-storing supercapacitors.

The Rice hybrid combines two-dimensional graphene, which is a sheet of carbon one atom thick, and nanotubes into a seamless three-dimensional structure. The bonds between them are covalent, which means adjacent carbon atoms share electrons in a highly stable configuration. The nanotubes aren't merely sitting on the graphene sheet; they become a part of it.

"Many people have tried to attach nanotubes to a metal electrode and it's never gone very well because they get a little electronic barrier right at the interface," Tour said. "By growing graphene on metal (in this case copper) and then growing nanotubes from the graphene, the electrical contact between the nanotubes and the metal electrode is ohmic. That means electrons see no difference, because it's all one seamless material.

"This gives us, effectively, a very high surface area of more than 2,000 square meters per gram of material. It's a huge number," said Tour, Rice's T.T. and W.F. Chao Chair in Chemistry as well as a professor of mechanical engineering and materials science and of computer science and a co-author with former postdoctoral researcher and lead author Yu Zhu, now an assistant professor at the University of Akron.

Tour said proof of the material's hybrid nature lies in the seven-membered rings at the transition from graphene to nanotube, a structure predicted by theory for such a material and now confirmed through electron microscope images with subnanometer resolution.

Carbon has no peer as a conductive material in such a thin and robust form, especially in the form of graphene or certain types of nanotubes. Combining the two appears to offer great potential for electronic components like fast supercapacitors that, because of the massive surface area, may hold a great deal of energy in a tiny package.

Rice chemist Robert Hauge and his team made the first steps toward such a hybrid over the past decade. Hauge, a distinguished faculty fellow in chemistry at Rice and co-author of the new work, discovered a way to make densely packed carpets of nanotubes on a carbon substrate by suspending catalyst-laced flakes in a furnace. When heated, the catalyst built carbon nanotubes like skyscrapers, starting at the substrate and working their way up. In the process, they lifted the aluminum oxide buffer into the air. The whole thing looked like a kite with many strings and was dubbed an odako, like the giant Japanese kites.

In the new work, the team grew a specialized odako that retained the iron catalyst and aluminum oxide buffer but put them on top of a layer of graphene grown separately on a copper substrate. The copper stayed to serve as an excellent current collector for the three-dimensional hybrids that were grown within minutes to controllable lengths of up to 120 microns.

Electron microscope images showed the one-, two- and three-walled nanotubes firmly embedded in the graphene, and electrical testing showed no resistance to the flow of current at the junction.

"The performance we see in this study is as good as the best carbon-based supercapacitors that have ever been made," Tour said. "We're not really a supercapacitor lab, and still we were able to match the performance because of the quality of the electrode. It's really remarkable, and it all harkens back to that unique interface."

Tips For Beginners On How To Land Educational Jobs In Well ...

According to many of today's young urban professionals, completing their university studies marked the end of the "easy" stage of their lives. Venturing into the fierce competition of the real world is always daunting because the overall dynamics are more challenging. For new teachers hoping to land educational jobs in schools overseas, the competition is even much tougher because many foreign teachers come to the country in hope of practicing their profession and improving their skills. If you're one of these greenhorns, you would really need to make adequate preparation to secure a job for yourself. You are required to go about your search for a job early and, more importantly, strategically.

Provided here are some tried and tested tips collected from former teaching hopefuls who managed to get some of the most important educational jobs after they left university.

First tip is to take advantage of the services of teaching agencies. It's always advantageous to sign up with an company that's directly linked with schools that need supply teachers and other school personnel. However, do not sign up with every teaching agency that you know; just stick to your top choices, such as the ones you know are associated with the learning institutions that you want to get into.

Second tip is if you're going to be a supply teacher, having a car is an advantage. You don't need to own the car, just one that will allow you to immediately meet the demand for a supply teacher. A lot of agencies make their job call in the morning, pretty much when the demand comes in so you need to be as prepared and flexible as you can be to accommodate the job. Don't look down on being a supply teacher; it's the perfect opportunity to gain experience or be recognized as an education professional and eventually secure that much coveted teaching job.

Third tip - again be flexible. If you're a new teacher, you would likely be tasked to take care of certain responsibilities that are not specific to the training you actually have. For example, if you majored in French Literature, you may also be asked to teach a different special subject. Prove your competence by being ready to study and take on a teaching duty. Look at this as an important learning experience that will add more to your credentials as a teacher.

Fourth tip is to assure your prospective employer that you are serious and have what it takes to be a figure of authority in the classroom. Present the disciplinary methods you adhere to, your own teaching style and principles. Credentials are impressive but they are often never enough in the real classroom setting; the key is to make the school administrators believe that you're the sole perfect person for the job and choosing you would be the most advantageous decision.

Being prepared always works to get that teaching job and while you're waiting for that call, continue to better yourself by studying further or getting teaching practice wherever you can.

For new teachers hoping to land educational jobs in UK schools, the competition is even much tougher because many foreign teachers come to the country in hope of practicing their profession and improving their skills.

Facebook stock climbs on backs of short-sellers

Facebook shares rose nearly 13 percent on Wednesday when insiders failed to flood the market with stock as expected and investors who sold the company short had to make good on their bets.

Facebook shares were up 12.9 percent to $22.36 at the close of the Nasdaq trading day and held the gain in after-market exchanges.

It was the second-best session for Facebook since its stock market debut in May, second only to its jump of nearly 20 percent in October after posting earning results that topped expectations.

Some analysts said Facebook shares climbed Wednesday on the backs of investors who sold stock short, anticipating prices would fall at the end of a lock-in period that had prevented the sales of more than 800 million shares held by social network employees.

"People were scared about the lock-up; a lot of people shorted (the stock)," said Social Internet Fund analyst Lou Kerner.

"As the lock expires, the shorts need to cover, and they are having to pay up to cover because the sellers aren't swamping the market."

In an effort to avoid big swings in its stock price, Facebook's initial public offering came with a set of lock-in periods during which shares held by investors or employees could not be sold.

One of those periods expired on Wednesday, when 804 million shares held by employees became eligible to be traded.

Facebook stock price dropped when two prior lock-in periods ended in August and October, so some investors essentially sold borrowed shares expecting to buy them back for less on Wednesday.

"The bottom line is there is no sure thing, and the shorts that held on got it wrong this time," Kerner said.

When sellers didn't flood the market as expected, investors "covering" short-sales of Facebook stock created buying pressure that pushed the price higher, according to analysts.

Some analysts saw Facebook shares as a promising long-term investment at well below the $38 price at which they made their stock market debut.

The California-based company has shown signs that it is dealing with what was considered a troubling flaw, figuring out how to make money off users increasingly using smartphones or tablet computers to connect with the leading social network.

Research reveals new understanding of X chromosome inactivation

Chapel Hill, NC In a paper published in the Nov. 21 issue of Cell, a team led by Mauro Calabrese, a postdoctoral fellow at the University of North Carolina in the lab of Terry Magnuson, chair of the department of genetics and member of the UNC Lineberger Comprehensive Cancer Center, broadens the understanding of how cells regulate silencing of the X chromosome in a process known as X-inactivation.

"This is a classic example of a basic research discovery. X-inactivation is a flagship model for understanding how non-coding RNAs orchestrate large-scale control of gene expression. In the simplest terms, we are trying to understand how cells regulate expression of their genes. Our findings are relevant across the board -- by understanding how normal cells function we can apply that knowledge to similar situations in the understanding and treatment of disease," said Calabrese.

Proper regulation of the X chromosome plays a crucial role in mammalian development. Females inherit a pair of X chromosomes from their parents, and the process of X-inactivation shuts down one of these two Xs.

"Males have XY. Females have two Xs. One of those Xs needs to get shut off. If it does not, it's not compatible with life. It's how we have evolved to equalize doses between males and females," said Calabrese.

While the manner in which the X chromosome is deactivated has been actively studied for 50 years, the exact mechanisms that regulate the process remain a mystery. Calabrese's research used high-throughput sequencing to determine the location and activity of chromosomes with far greater accuracy than previous research.

"Basically, this is using the sequencing technology as a high resolution microscope," said Calabrese.

Under a microscope, the inactive X chromosome (Xi) appears as a cloud-like structure, because it is covered with a non-coding RNA known as Xist. In the traditional model of X-inactivation, genes located inside the cloud are completely silenced, with 15 percent of the genes from the inactive X chromosomes escaping to become active.

"The prevailing thought was that genes that escaped X inactivation were pulled out of the core and expressed out there," said Calabrese.

The work of Calabrese's team complicates the current model of X-inactivation by finding indications of gene activity inside the Xist cloud and the presence of inactive genes outside the cloud, both of which would not have been thought possible in the prevailing model.

"It's kind of a subtle thing, but mechanistically it is a big difference," said Calabrese.

Inside the Xist cloud, sequencing discovered traces of DNase I sensitivity, a feature usually linked to transcription activity. While other markers associated with transcription were absent, the presence of DNase I sensitivity suggested that the nucleus did recognize the inactive X as usable DNA, but an unknown suppressive mechanism was preventing genes from being activated.

"We were surprised to see that. If they were totally silent, you would expect this to be not there This suggests that transcription factors or other proteins that bind DNA are still accessing the inactive X," said Calabrese.

The other surprising findings involve the 15 percent of "escaper" genes from the inactive X. Calabrese found evidence that active genes were found both inside and outside the Xist cloud, and that silenced genes that lay alongside active genes outside of the Xist cloud remained inactive.

"If X-inactivation was a strict nuclear barrier, then pulling a gene outside the barrier would turn it on, but it has got to be more than that because when an inactivated gene that is beside an escaper is outside this domain, it is still turned off," said Calabrese.

The presence of DNase I sensitivity within the Xist cloud and the finding of inactive genes outside of the cloud suggest that a site-specific mechanism is regulating genes on the chromosome in a more subtle way than the binary "on/off" function posited by the prevailing model. The exact mechanism for this remains unknown. Although Calabrese believes that Xist still plays a role, its exact function and whether other factors influence X-inactivation remain questions for future research.

"We know that Xist is required to turn off the inactive X. We know that. We have no idea how" said Calabrese.

Beyond revising the understanding of how X-inactivation works, Calabrese said that deeper understanding of the function of Xist could reveal more about the role of other non-coding RNAs in cellular development. These RNAs could become useful targets for future therapies and drug development.

"We know that too much expression of the wrong non-coding RNAs can lead to cancer. Also, forced expression of other non-coding RNAs can prevent cancer. Generally, we do not know how these RNAs work," said Calabrese.

Scientists design 3-D printed satellite

19 min.

Seeking?a low-cost way to launch their experiments into space, a team of scientists has designed a space-ready, 3-D printed CubeSat.

CubeSats are standardized, tiny satellites, often only 3.9 inches on each side and weighing just under 3 pounds. They are so small that they have room for only a few sensors, and burn up in the Earth's atmosphere after just a few months. Kits cost under $10,000, which is considered cheap for the space industry. But Jacopo Piattoni of the University of Bologna and his team aim to drive the satellites' price down even further, while making the devices easier to customize.

In 3-D printing, a computer-directed nozzle "prints" a three-dimensional object in plastic. Often, engineers use this method to design a prototype for a product that will then be built out of metal or another, sturdier medium. But Piattoni?s team hopes their plastic CubeSat could survive launch and low-Earth orbit.

Using 3-D printers, researchers can automate the CubeSat production process. ?We don?t need a technician,? Piattoni said, adding that this also makes the process faster.

[NASA Turns to 3-D Printing for Self-Building Spacecraft]

The CubeSat?s sensors and computer chips, of course, weren't printed in the lab, and the team had to add a small, metal heat sink to disperse the electronic components' heat. The method holds promise, though. When the researchers tested the chassis in near-space conditions, "it did really well," Piattoni said.

Piattoni chose ABS plastic, the same type of plastic used in Lego bricks, to construct his CubeSat because of that material's resilience to extreme temperatures, vibrations, radiation and more. A satellite will absorb a lot of solar radiation during its spaceflight, and its temperature will swing from -4 degrees F (-20 degrees C) to 176 degrees F (80 degrees C) each orbit. "It's not so easy for plastics in that environment," Piattoni said.

In fact, ABS plastic was famously indicted in a massive seat-belt buckle recall in the mid-90s because UV radiation weakened buckles made from the material. But such radiation, even at elevated levels, won't pose a problem for the CubeSat, due to its short lifetime.

With one successful satellite constructed, the team can now use the 3-D printer to crank out another copy each night. They can also test new designs or build support for other sensors or modules, just by clicking a few buttons on a computer.

The final product passed its tests with flying colors. Now, like most other CubeSats, it will hitch a ride into space as secondary cargo on a rocket already headed to its preferred orbit. Piattoni's team is working with QB50, which will put 50 CubeSats into orbit at once on a Russian Shtil-2.1 scheduled to launch in 2014.

The satellite was designed and tested by Piattoni and researchers in the University of Rome's Department of Astronautical, Electrical and Energy Engineering and the Department of Mechanical and Aerospace Engineering.

RetailMeNot Facebook App: Improved Targeting | Small Business ...

More and more consumers are steering away from traditional paper coupons in favor of electronic deals and coupon codes. But not only can these electronic coupons be more convenient for consumers, they can also allow for more effective targeting and analytics options for the businesses that offer them. And since social media sites hold so much information about their users and their interests, it only makes sense that these sites could assist businesses better target deals to their best customers.

RetailMeNot

Coupon website RetailMeNot just launched a Facebook app that recommends deals and coupons based on users? Likes and interests.

The RetailMeNot site, which currently boasts more than 500,000 offers a year, can often seem overwhelming for consumers looking for deals. But the new Facebook can help make these offers more relevant to consumers, and thus more effective for the businesses that submit offers.

Users of the RetailMeNot app simply give it permission to see their Likes, and then they can also select a few of their favorite retailers in order to get an even more personalized feed of offers and coupons. Then, over time, the RetailMeNot app also takes into account the offers that users click.

The photo above shows the Facebook app, which includes a customized feed of coupons and offers. It details how much of a discount the user can receive, the expiration date, and more personalized information. Users can also save coupons and add favorite stores to their preferences.

Coupon codes can be submitted by any online retailer, and printable coupons that include scannable bar codes can be submitted by local stores. In addition, the site allows businesses to submit sales or shopping tips that just give consumers information about saving money.

To submit a coupon or sale, you need only create an account and then provide the name of the retailer, type of deal, and any other information necessary for shoppers to redeem the offer.

Offers are then reviewed by the site and often go live within a few hours. You can then track how many users have redeemed your coupon and how much they saved.

RetailMeNot was launched in 2006 and is owned by Whale Shark Media. RetailMeNot also offers a coupon app for iPhone, as well as a weekly email with a stream of recent deals.

Bell, Virgin Mobile Canada reportedly start unlocking iPhones, at a steep cost (update: Telus does too)

Bell, Virgin Mobile Canada to start unlocking iPhones, at a steep cost

Canadians have had the option to buy a factory-unlocked iPhone for awhile, but liberating Apple's handset after the sale has been officially limited to Rogers and Fido customers. As long as MobileSyrup's leak is the real deal, though, subscribers to Bell and its Virgin Mobile branch can spring for an unlock as of today. That's good news for many, although the hurdle is once again the carrier's desire to keep customers from jumping ship. Those pursuing an unlock will supposedly need to be out of contract, skip any prepaid plans and pay a $75 fee -- in short, they're more likely to derestrict an old, well-worn iPhone than the iPhone 5 they bought last week. We'll just be happy to have another route to hardware independence, and hope that the mention of widened unlock eligibility in 2013 is more than just a rumor.

Update: Telus lets you unlock as well, so this mostly completes the big three carriers. Thanks, Tim!

Chris Kelly: Crouching Fiscal Cliff, Hidden Aircraft Carrier

Over the weekend, a Chinese knock-off of a Russian fighter jet, the J-15, landed on China's used Ukrainian aircraft carrier, the Liaoning, for the first time. Luo Yuan, the senior engineer of China's aircraft carrier program, was there to witness this historic event and subsequently dropped dead. He was 51. Mao tells us that all men must die, but death can vary in significance; to die for the people is weightier than Mount Tai, but to work for the fascists and die for the exploiters and oppressors is lighter than a feather. Given China's new role, as the world's sweatshop, and the symbiotic relationship between its arms spending and ours, it would have been illuminating to know what Luo weighed when he expired.

The Chinese hold over a trillion dollars in American debt. That's less than 9% of what we owe, but it means the Chinese profit, in a very direct and tangible sense, from our obsessive deficit spending on defense. And who are we defending ourselves from? The Chinese.

So Luo was serving the people, while frightening the exploiters, who will borrow more money, to buy weapons, to defended themselves from the people... from the people.

That's some serious weight.

I'm feeling sort of logy myself. I may have to lie down.

How scared should we be, of the Chinese and their nascent ability to put a plane on a boat? Scared shitless, according to the people who sell us our planes and boats. This means that They are catching up.

It feels like barely 101 years ago that the first American landed a plane on a warship, because it was. And now foreigners are doing it too.

The gap is closing. While we slept, the dragon was breathing down our necks, having crossed the Rubicon inside a Trojan horse.

Hauntingly, and there's no such thing as accidents, this new threat is emerging just as America faces the Fiscal Cliff, and spending cuts that could hollow out our defense like a cheap chocolate Easter Bunny.

This is no time for reckless fiscal restraint. I'll let the Heritage Foundation explain:


Chinese Throwing Their Weight Around
For the U.S., the incorporation of the Liaoning into the PLAN (People's Liberation Army Navy) means that the Chinese will be a growing factor in waters that have long been an American preserve... it is possible that the Chinese will choose to dispatch it to the American exclusive economic zone (EEZ) to counter American freedom of navigation activities in what the Chinese claim as their EEZ.

It's also possible that they'll release a Kraken, but unlikely. America has 11 carrier groups. China has one pokey carrier, and a handful of destroyers to support it. Imagining the Liaoning menacing the "freedom of navigation activities" of the nuclear super carrier Abraham Lincoln isn't just disingenuous, it's fantastical. The Foundation is treating you like an asshole. But here's their larger point:


What the U.S. Should Do
Provide more defense resources. Meeting military requirements is likely to mean more defense spending, not less. Already enacted budget cuts, not to mention those demanded by sequestration, cannot be reconciled with meeting ongoing or future defense needs.

Balancing the budget is fine, in theory, if all you're talking about is cutting Medicare, education, Social Security and the EPA. But not defense. Not with the Liaoning out there.

Sequestration - the Fiscal Cliff to its friends - would trigger a 9.4% cut in defense spending. The savings won't come from Afghanistan or Iraq - the White House and Congress agreed a long time ago that wars don't come out of the Pentagon's allowance. The savings also won't come from military personnel or veterans affairs. They're exempt from sequester. That leaves the big-ticket items. Like the aircraft carriers and destroyers, submarines, helicopters and planes, missiles and satellites that we'd need to fight another navy, if anyone had one.

Like for instance China.

Speaking of Kraken, when Zeus beat Echidna, half woman/half snake, he didn't kill her, although he could have. He let her live, and become the mother of all monsters, so the heroes would have something to do.

Because you know Zeus. It was all about jobs.

Its a Wonderful Movie: Reviews for Hitched for the Holidays and More!

Hello Everybody...

I certainly hope you all had a wonderful and most importantly, memorable - Thanksgiving Weekend! Four generations of family gathered at our home, and each year I learn... giving thanks and being with those you love is better than any feast or delicious dessert!

undefined
I took a little blogging break over the weekend, but was delighted to see my inbox was filled this morning with various comments and reviews of this weekends Christmas movies, from Many of You! Either you loved them or ... let's just say you didn't love them.

Anyway, Hitched for the Holidays seems to have been a strong winner, and I would have to agree! It was adorable, witty, and loads of fun! Joey Lawrence was fantastic!

One person shared: "This was suprisingly wonderful! This is the best Hallmark holiday movie of the season!"

Plus, it wasn't just a great Christmas Movie - it also included Thanksgiving, Hanukkah, and New Years Eve! It was one of those movies you just know you'll look forward to watching over and over again!

As for other Movies - Naughty or Nice got mixed reviews. Some said it was cute while others didn't like her boring cheating boyfriend, Australian sounding boss, or klepto neighbor. I agree with both points of view on this one. The elf moments at the mall were super funny, especially with her new co-worker! And, the Naughty or Nice book was kind of fun - made me wish I could have one!

Let's see... you thought the?Jingle and Bell's Christmas Star cartoon was Sweet. Me too! Heartland Christmas was warm and family friendly. Favorite part - Christmas Day Dinner with the family and Frosty (at the end)!

Golden Christmas 3 was a blend of the original two movies ? A Golden Christmas and A Golden Christmas 2. Again, the dogs must help play match-maker by running off and forcing their owners to chase them ? and run into (literally) their first love. The second one is still my favorite of the series.

I didn't get a chance to personally see GMC's The Christmas Angel or any of Lifetime's new Christmas Movies, but I appreciated you all letting me know what you thought. You thought The Christmas Angel was Great - but the Lifetime Movies Not-so-Great. One person did say they liked The March Sisters at Christmas while several others said they did not - and Love at the Christmas Table, someone shared that it is just not good.

No Reviews have come in, yet, for Home Alone : The Holiday Heist. I'm sure it is hard for them to be compared to the original.

So... what do you think? Did you have a nice Thanksgiving? Did you see any of these new Christmas Movies over the weekend? I would love to hear from you, too!

KARBALA, Iraq (AP) ? It is the most impassioned day of the year for Shiite Muslims ? Ashoura, when one of the faith's most revered figures, Imam Hussein, was martyred in battle. Hundreds of thousands of Shiites who flocked to his resplendent, gold-domed shrine to commemorate him Saturday found the site has radically changed.

The shrine of Imam Hussein, the grandson of the Prophet Muhammad, is seeing its most extensive renovation since the 17th century. The construction is part of a push by Iraq's Shiite rulers to reinvigorate sacred shrines long neglected under former dictator Saddam Hussein, reflecting the community's steadily growing pride and power since the fall of their nemesis.

Now worshippers find the shrines' minarets coated in gold and ? in the most dramatic change ? the sweeping plaza surrounding the mosque has been covered over with a series of domes to provide shade from the hot sun in the desert city of Karbala.

Not everyone is happy with the changes. Five experts on the shrine, including three who advised on individual parts of the renovation, say the drama of the shrine has been lost.

The covering of the once-open plaza, they argue, ruined the visual experience. Pilgrims no longer can see the awe-striking view of the mosque as they pass through the sprawling, light-filled plaza, then into the dazzlingly colorful mosque, finally reaching their ultimate destination: Hussein's richly ornate tomb, they said.

"They sacrificed considerations of Islamic architecture to do it," said Haider Naji, one of the experts.

On Saturday, throngs of Shiites who came from across the country ? some marching for miles on foot in processions ? converged on the shrine, one of the holiest sites of the faith. Men cloaked in black beat giant drums, youths blew military-style bugles, and others carried platters of sweets to sustain energy, decorated with dyed pink and blue feathers.

Outside the shrine, the crowds held Ashoura's blood-soaked, emotional pageantry of grief. Men and boys dressed in white burial shrouds ? to show their willingness to die for Hussein ? whipped their backs with chains and cut their heads with knives, drenching themselves in blood to mourn his loss. Men and women wailed in mourning, breaking down into tears.

Others dressed as the historic figures from the 7th century battle ? Hussein, in green, and his enemies, in red, with turbans decked with feather plumes, leather battle vests and swords. A fountain of fake red blood bubbled before the shrine. A horse covered with a sheet stained red was led through the crowds, representing Hussein's white steed Zuljanah, which is said to have been riddled by arrows as it tried to shield its wounded master.

Ashoura marks the martyrdom of Hussein in a battle at Karbala in the deserts south of present-day Baghdad. The event is one of the defining moments in the split between the Sunni and Shiite sects of Islam.

Shiites believe Hussain's father Imam Ali was Muhammad's rightful successor and that was he unfairly passed over by the caliphs considered by Sunnis as the rightful line. Hussein led a revolt against the Damascus-based Sunni caliph, who sent an army that crushed Hussein's small band of fighters at Karbala.

In commemorations for Ashoura held by Shiites around the world Saturday, details of the battle are retold or recreated in passion plays that bring wails of sorrow and pity from the crowds.

The stories are deeply engrained in Shiites' consciousness. The agonizing thirst of Hussein's wife and children in the desert after the besieging enemy stopped their water supply. The heroic, doomed attempt to bring them water by Hussein's half-brother al-Abbas, who ? even after the enemy cut off his arms ? rode gripping the water-skin in his teeth until he died in a hail of arrows. The killing of Hussein's loyalists one by one until Hussein was alone, wounded and finally beheaded.

So strong are the passions that onlookers sometimes stone the actor playing Hussein's killer, Shimr. At a Baghdad shrine on Saturday, the play's "Shimr" broke character to weepingly ask the audience's forgiveness, pleading that someone had to take the role.

The day has often been a chance for Sunni militants to attack Shiites, whom they see as heretics. Iraq has seen repeated deadly bombings against Ashoura ceremonies in past years, though there were no immediate reports of violence this year. In Pakistan's tribal region on Saturday, a bomb blast struck an Ashoura procession, killing seven people, including three children.

The renovations at the shrine in Karbala are the latest evolution in what was once the austere, tree-marked grave of Hussein. Over the centuries, it became more ostentatious, culminating in the shrine built in the 17th century by artisans from the nearby Persian Safavid empire, according to Ghada Razouki, an expert in medieval Islamic architecture.

Under the shrine's gold-plated dome, Hussein's sarcophagus is drenched five tons of silver and 120 kilograms (260 pounds) of engraved gold. The mosque is etched inside and out with geometrical designs, verses from the Quran and the names of Muhammad's family in green, blue and yellow. Tiny mirrors reflecting light line the arched ceiling above the sarcophagus.

The current renovations, launched in 2005, aim to provide more room to crowds reaching some two million pilgrims, said Sheik Salah al-Haydari, head of the Shiite Muslim endowment, which has overall control of Iraq's Shiite shrines.

The plaza that surrounds the shrine has been covered over with the domed roof and will be expanded four-fold to 24,000 square meters (260,000 square feet) by 2013, said Mohammed Kadhem, who is leading the $50 million project. One extension of 6,000 square meters (65,000 square feet) has been completed.

The ancient wall surrounding the shrine has been replaced with multi-level buildings with extra prayer spaces, offices and a museum. The shrine's minarets were coated in gold.

Al-Haydari countered the criticisms, saying, "We are continuing the architectural style that is there, like a river continuing its path."

To recreate the dramatic open space around the shrine, urban planners reviving Karbala's old city will increase plaza space outside the site's gates, said Mohammed al-Assam of Dewan Architects.

Shiite officials are also renovating the shrine of al-Abbas next to Hussein's, that of Imam Ali in neighboring Najaf, and the shrine of his descendants in Baghdad.

The rush to improve the shrines became more determined after al-Qaeda militants in 2006 blew up the golden dome of a shrine in Samarra, north of Baghdad. The destruction of the al-Askari shrine ? now rebuilt ? underscored to Shiite officials the need to rebuild and glorify their shrines to demonstrate their growing power.

"Shiite areas are now in the hands of Shiites. What is happening is natural and it shows their control," said analyst Hadi Jalo.

In contrast to the architects, worshippers aid the changes to the once-neglected shrine should have been even grander.

"All these changes are but a little for the Imam Hussein," said Ahmad Ali, who just arrived in Karbala from Baghdad. "But thank God it's better than before: there's air conditioning, protection from the sun and rain," he said.

Speaking before walking from Baghdad to Karbala, Abdullah Ashraf, 25, said worrying about changes to the shrine misses the point.

"What makes the Hussein shrine alive is the memory of his story."

Think your office has long meetings? Try China's Party confabs

China's leaders have refined the endless-meeting concept to an exquisite level of pointlessness ? making the country's?progress over the past 30 years even more remarkable.

By Peter Ford,?Staff writer / November 9, 2012

Members of the Xinjiang provincial delegation and representatives from the National People's Congress (NPC) attend a meeting in the Xinjiang Room inside the Great Hall of the People in Beijing, Friday, Nov. 9. The banner reads: '18th National Congress of the Communist Party of China (CPC), Xinjiang Uyghur Autonomous Region Representative Committee.'

But the Chinese Communist Party has refined the endless meeting to an exquisite level of pointlessness, and on Friday, when journalists were invited to sit in on ?private? discussions among delegates to the 18th?Party Congress, the phenomenon was on full display.

None of us had expected lively and spontaneous debate about the speech that party leader Hu Jintao had given on Thursday at the opening of the Congress. That is not the way things work here.

But there was no discussion of any description of the speech at any of the three gatherings that I attended in ornately decorated, thickly carpeted, marble pillared meeting rooms in the gigantic Great Hall of the People.

The Shanxi provincial delegation meeting seemed pretty typical. Thirty or so delegates were sat around a U-shaped table, and one by one they made their speeches.

'Yesterday, I heard Hu Jintao's report'

?Yesterday, I listened to Hu Jintao?s report and I found it very profound and very correct,? said Wu Huada, president of a coalmining company, before reading his prepared remarks about improved mine safety in Shanxi.

?I heard Hu Jintao?s report yesterday, and I firmly support this report,? said Niu Guodong, who introduced himself as a worker at the largest stainless steel factory in the world, and then read from a text explaining the energy saving measures the factory has introduced.

?Yesterday, I heard President Hu Jintao?s report and it expressed the will of people across the nation. I shall study it further,? promised Li Fei, a local party secretary, who then read her speech detailing the number of kilometers of road paved recently and the number of rural schools that had been remodeled in the county she rules.

All over the Great Hall of the People, in room after room, delegates were droning on about things their audiences knew already, or if they didn?t know, they evidently did not care about. Some stared into the middle distance; others pored over the speeches they themselves were about to make; some openly read a newspaper, or dozed.

The whole exercise appeared to strike them as a monumental waste of time; everything had been scripted in advance, and everyone had heard it all before.

Nor are these sorts of meeting uncommon in China. This was the cream of the Communist Party, but officials at all levels of the Chinese system spend huge amounts of time engaged in similar meetings.

It struck me that the progress China has made in so many spheres over the past 30 years is even more remarkable when you take into account that its successes have been achieved even though the people running the country waste so much of their time in endless and pointless meetings.

A Chinese colleague, however, had a more cynical take on what we were witnessing. ?It just shows,? she said, ?that the country goes on running perfectly well even without all these guys while they waste their time at meetings.??

Ultrasound pictures show difference in fetus yawning and other mouth openings

Thursday, November 22, 2012

Ultrasound scans of faces in utero can distinguish between when a fetus yawns and when it just opens its mouth, according to research published November 28 in the open access journal PLOS ONE by Nadja Reissland from the University of Durham and colleagues at other institutions.

The researchers found that during the period between 24 to 36 weeks of gestation, they could distinguish between yawns and simple mouth openings on ultrasound images of fetal faces. They report that simple mouth openings occur less often than yawns and the frequency of these openings declines from 24 weeks of gestation onward. More than half of all mouth openings are yawns at 24 weeks of gestation, and the frequency of yawns begins to decline at a later stage (28 weeks onward).

The study suggests that trends in yawning behavior may potentially be used to track healthy fetal development. Reissland says, "Fetus yawning is not contagious, nor do they yawn because they are "sleepy". Instead, frequency of yawning in the womb might be related to activity-dependent brain maturation early in gestation."

Deal on 'fiscal cliff' would limit deficit reduction

24 min.

As Congress and the White House settle in to a new round of talks over the federal budget, there are no good choices. If there were, the impasse would have been resolved a long time ago.

But as both sides vow to reach a compromise, it?s becoming clear that any bipartisan agreement will ?fall far short of the current law in cutting the $1.1 trillion federal deficit. ??

The current budget law that created the so-called ?fiscal cliff? was written in a high-stakes moment in July 2011 as an impasse over raising the federal debt ceiling left the Treasury just days away from defaulting for the first time in history. The law?s architects, who well understood the dire consequences of allowing massive tax hikes and spending cuts to take effect, created the law as a club to force action after the November election.

Now that the election is over, leaders of both political parties have expressed the desire to come to an agreement and end the long deadlock.

But with the composition of Congress largely unchanged, any?tax hikes and spending cuts both will likely be far smaller than what each side might want.

"The split in Congress will force both sides to bargain,? said?economist Paul Ashworth of?Capital Economics. ?We expect the?Democrats?to agree to extend the Bush-era (tax cuts) for higher income earners in exchange for Republicans agreeing to put off the spending cuts."

On Sunday, Sen. Bob Corker, R-Tenn., expressed confidence that a deal could be reached, and Obama aide David Axelrod hinted at compromise on raising tax rates on the rich, a key White House priority.

House Speaker John Boehner, R-Ohio, last week opened the door to compromise on his party's commitment to not raise tax rates, saying he would support changes in the tax code that bring in more revenue.

Obama has invited congressional leaders to the White House on Friday to discuss the issue.

There had been hope that last week's election might break the longstanding political deadlock that has thwarted action. Republicans hoped to gain control of both?the Senate and White House, the better to fulfill promised deep spending cuts. If?Democrats had been able to gain control of both the House and Senate, they would have faced less opposition to tax hikes.

The continuing divided control in Washington means that?a successful bipartisan agreement will have less to do with deficit reduction than with dodging the political backlash that would ensue if automatic spending cuts and tax hikes are allowed to take place, potentially sending the economy?back into recession next year.

Unless amended, the current law ends Bush-era tax cuts, raising taxes by roughly $330 billion at a cost of about $3,500 for every household. ?Also on the block is the Obama administration's two-year payroll tax cut, which would cost wage earners another $95 billion. Other provisions, including the elimination of a ?deduction for sales tax, would raise taxes by another $65 billion.

Spending cuts in the law include a?$55 billion or?9 percent cut in the defense budget next year and another $55 billion in cuts to domestic programs, including a 2 percent or $11 billion?cut to Medicare providers. Long-term unemployment benefits would by cut by $26 billion.

While painful, those measures - if left in place - would only cover roughly half the annual federal budget gap.

All of which means that as the odds of meaningful deficit reduction grow slimmer as both sides move closer to a compromise.?

Democrats, including President Barack?Obama, have said?any compromise should include higher taxes on the top earners who make more than $250,000 a year. But that would raise only?about $42 billion, according to the Congressional Budget Office. That amounts to about 3 percent of the annual deficit.

Balancing the budget with spending cuts has proven even harder, largely because so much of the budget is devoted to historically ?untouchable? categories like defense and direct payments to taxpayers. Social Security, Medicare and defense spending consume 60 cents of every tax dollar. Add pensions for federal workers and veterans, safety net programs like unemployment insurance and interest on the debt, and there?s roughly 20 percent of the federal budget left open to cutting.

That?s why Congress has made so little progress over the years finding ways of postponing the tax hikes and spending cuts required to bring the budget into balance.

In the short run, the cost of delay may not be so dire.

Despite the dire warnings of sudden fiscal impact, the cliff is more like a slope, as the economic impact?would?be felt gradually.

The average U.S. household would see a tax increase of about $68 a week, adding up to?$3,500 if Congress fails to act over the full year.

On the spending side, most government agencies facing cuts have broad discretion on how they phase them in over the remainder of the fiscal year, which ends Sept. 30. If Congress and the White House don?t reach a deal by Jan.1, some agencies could decide to continue spending at current rates, with the expectation that a deal would be reached sometime next year that to pare back spending cuts ? or postpone them altogether.

Congress has also bought time with the help of the Federal Reserve, which responded to the financial collapse of 2008 by slashing interest rates to record lows. Just as homeowners have saved tens of billions of dollars on lower mortgage rates, the federal government has seen its cost of borrowing fall sharply ? even as the size of the debt has increased.

In fiscal 2008, the Treasury spent $451 billion in interest on roughly $10 trillion in public debt outstanding. For the fiscal year that ended Sept. 30, Uncle Sam paid just $360 billion to service debt of more than $16 trillion.?

But the Federal Reserve can?t keep rates low forever. Those low rates rely heavily on investors? belief in the safety of U.S, Treasury debt, which faces another downgrade if rating agencies decide the government has lost control of its finances.? If investors stop buying U.S. bonds, borrowing costs could rise and the value of the dollar would fall.

So while some have suggested that the economic threat of fiscal cliff has been overstated, the potential financial disaster of expanding deficits is very real, according some financial analysts, including Peter Schiff, CEO of Euro Pacific Capital.

?That disaster will take the form of a dollar and/or sovereign debt crisis that will make the fiscal cliff look like an ant hill,? he said.
