UFC on Fox 2?s Three Stars: Oliveira, Johnson and Evans

The UFC's second foray into network television was not exactly thrilling. Some of the best moments happened during the Fuel broadcast, with the fights on Fox providing less-than-exciting action. Who stood out for you? Here are Cagewriter's Three Stars. Tell us yours in the comment section or on Facebook.

No. 1 star -- Charles Oliveira: In his first fight at featherweight, the Brazilian used a leg submission that caused every MMA writer on press row to say, "What was that?" We settled on a calf slicer, while Oliveira walked away with the Submission of the Night bonus.

No. 2 star -- Lavar Johnson: If you haven't watched Johnson's KO of Joey Beltran, go watch it. We'll wait. OK, now that you've watched him take out Beltran with huge uppercuts, you likely will agree with him taking home the Knockout of the Night bonus.

No. 3 star -- Rashad Evans: Put yourself in Evans' shoes. Though you're the No. 1 contender for the light heavyweight belt, injury and bad luck has forced you out of the actual title bout more than a year. Then, you're told you still have to win another fight to get that title shot. You could sulk about it, or you could use the five rounds provided to beat up and outwrestle Phil Davis. Evans chose the latter.

Terahertz polarizer nears perfection: Research leads to nanotube-based device for communication, security, sensing

ScienceDaily (Jan. 30, 2012) ? Researchers at Rice University are using carbon nanotubes as the critical component of a robust terahertz polarizer that could accelerate the development of new security and communication devices, sensors and non-invasive medical imaging systems as well as fundamental studies of low-dimensional condensed matter systems.

The polarizer developed by the Rice lab of Junichiro Kono, a professor of electrical and computer engineering and of physics and astronomy, is the most effective ever reported; it selectively allows 100 percent of a terahertz wave to pass or blocks 99.9 percent of it, depending on its polarization. The research was published in the online version of the American Chemical Society journal Nano Letters.

The broadband polarizer handles waves from 0.5 to 2.2 terahertz, far surpassing the range of commercial polarizers that consist of fragile grids wrapped in gold or tungsten wires.

Kono said technologies that make use of the optical and electrical regions of the electromagnetic spectrum are mature and common, as in lasers and telescopes on one end and computers and microwaves on the other. But until recent years, the terahertz region in between was largely unexplored. "Over the past decade or two, people have been making impressive progress," he said, particularly in the development of such sources of radiation as the terahertz quantum cascade laser.

"We have pretty good terahertz emitters and detectors, but we need a way to manipulate light in this range," Kono said. "Our work is in this category, manipulating the polarization state -- the direction of the electric field -- of terahertz radiation."

Terahertz waves exist at the transition between infrared and microwaves and have unique qualities. They are not harmful and penetrate fabric, wood, plastic and even clouds, but not metal or water. In combination with spectroscopy, they can be used to read what Kono called "spectral fingerprints in the terahertz range"; he said they would, for instance, be useful in a security setting to identify the chemical signatures of specific explosives.

The work by Kono and lead author Lei Ren, who recently earned his doctorate at Rice, makes great use of the basic research into carbon nanotubes for which the university is famous. Co-authors Robert Hauge, a distinguished faculty fellow in chemistry, and his former graduate student Cary Pint developed a way to grow nanotube carpets and to transfer well-aligned arrays of nanotubes from a catalyst to any substrate they chose, limited only by the size of the growth platform.

While Hauge and Pint were developing their nanotube arrays, Kono and his team were thinking about terahertz. Four years ago, they came across a semiconducting material, indium antimonide, that would stop or pass terahertz waves, but only in a strong magnetic field and at very low temperatures.

At about the same time, Kono's lab began working with carbon nanotube arrays transferred onto a sapphire substrate by Pint and Hauge. Those aligned arrays -- think of a field of wheat run over by a steamroller -- turned out to be very effective at filtering terahertz waves, as Kono and his team reported in a 2009 paper.

"When the polarization of the terahertz wave was perpendicular to the nanotubes, there was absolutely no attenuation," Kono recalled. "But when the polarization was parallel to the nanotubes, the thickness was not enough to completely kill the transmission, which was still at 30-50 percent."

The answer was clear: Make the polarizer thicker. The current polarizer has three decks of aligned nanotubes on sapphire, enough to effectively absorb all of the incident terahertz radiation. "Our method is unique, and it's simple," he said.

Kono sees use for the device beyond spectroscopy by manipulating it with an electric field, but that will only become possible when all of the nanotubes in an array are of a semiconducting type. As they're made now, batches of nanotubes are a random mix of semiconductors and metallics; recent work by Erik H?roz, a graduate student in Kono's lab, detailed the reasons that nanotubes separated through ultracentrifugation have type-dependent colors. But finding a way to grow specific types of nanotubes is the focus of a great deal of research at Rice and elsewhere.

Co-authors are former Rice postdoctoral researcher Takashi Arikawa and research associate Iwao Kawayama and Professor Masayoshi Tonouchi of the Institute of Laser Engineering at Osaka University, Japan.

The Department of Energy, the National Science Foundation and the Robert A. Welch Foundation supported the research.

29 Chinese missing after militant attack in Sudan (AP)

BEIJING ? Militants apparently captured 29 Chinese workers after attacking a remote worksite in a volatile region of Sudan, and Sudanese forces were increasing security for Chinese projects and personnel there, China said Sunday.

China has close political and economic relations with Sudan, especially in the energy sector.

The Foreign Ministry in Beijing said the militants attacked Saturday and Sudanese forces launched a rescue mission Sunday in coordination with the Chinese embassy in Khartoum.

The Ministry's head of consular affairs met with the Sudanese ambassador in Beijing and "urged him to actively conduct rescue missions under the prerequisite of ensuring the safety of the Chinese personnel," the statement said.

In Khartoum, a Chinese embassy spokesman said the northern branch of the Sudan People's Liberation Movement announced that 29 Chinese workers had been captured in the attack. The spokesman, who asked not be identified, gave no other details and it wasn't clear if the militants had demanded conditions for their return.

Other details weren't given. The official Xinhua News Agency cited the state governor as saying the Sudan People's Liberation Army attacked a road-building site in South Kordofan and seized the workers.

The Sudan People's Liberation Army are a guerrilla force loyal to the southern movement and hail from a minority ethnic group now in control of much of South Sudan, which became the world's newest country only six months ago in a breakaway from Sudan.

Sudan has accused South Sudan of arming pro-South Sudan groups in South Kordofan. The government of South Sudan has called such accusations a smoke screen intended to justify a future invasion of the South.

China has sent large numbers of workers to potentially unstable regions such as Sudan and last year was forced to send ships and planes to help with the emergency evacuation of 30,000 of its citizens from the fighting in Libya.

China has consistently used its clout in diplomatic forums such as the United Nations to defend Sudan and its longtime leader Omar al-Bashir. In recent years, it has also sought to build good relations with leaders from the south, where most of Sudan's oil is located.

Chinese companies have also invested heavily in Sudanese oil production, along with companies India and elsewhere.

Etta James remembered as triumphant trailblazer (AP)

GARDENA, Calif. ? Etta James was remembered at a service Saturday attended by hundreds of friends, family and fans as a woman who triumphed against all odds to break down cultural and musical barriers in a style that was unfailingly honest.

The Rev. Al Sharpton eulogized James in a rousing speech, describing her remarkable rise from poverty and pain to become a woman whose music became an enduring anthem for weddings and commercials.

Perhaps most famously, President Barack Obama and the first lady shared their first inaugural ball dance to a version of the song sung by Beyonce. Sharpton on Saturday opened his remarks by reading a statement from the president.

"Etta will be remembered for her legendary voice and her contributions to our nation's musical heritage," Obama's statement read.

The Grammy-winning singer died Jan. 20 after battling leukemia and other ailments, including dementia. She had retreated from public life in recent years, but on Saturday her legacy was on display as mourners of all ages and races converged on the City of Refuge church in Gardena, south of downtown Los Angeles.

Among the stars performing tributes to James were Stevie Wonder and Christina Aguilera, who told the gathering that she has included "At Last" in every concert she's performed as a tribute to her musical inspiration.

Wonder performed three songs, including "Shelter In the Rain" and a harmonica solo. James' rose-draped casket was on display, surrounded by wreaths and floral arrangements and pictures of the singer.

Sharpton, who met James when he was an up-and-coming preacher, credited her with helping break down racial barriers through her music.

"She was able to get us on the same rhythms and humming the same ballads and understanding each other's melodies way before we could even use the same hotels," Sharpton said.

He said James' fame and influence would have been unthinkable to a woman with James' background ? growing up in a broken home during segregation and at times battling her own demons.

"The genius of Etta James is she flipped the script," Sharpton said, alluding to her struggles with addiction, which she eventually overcame.

"She waited until she turned her pain into power," he said, adding that it turned her story away from being a tragic one into one of triumph.

"You beat `em Etta," Sharpton said in concluding his eulogy. "At last. At last. At last!"

The assembly roared to their feet, and would again stand to applaud performances by Wonder and Aguilera, who filled the sanctuary with their voices.

"Out of all the singers that I've ever heard, she was the one that cut right to my soul and spoke to me," Aguilera said before her performance.

Throughout the service, a portrait of James as a woman who beat the odds in pursuit of her dreams repeatedly emerged.

"Etta is special to me and for me, because she represents the life, the triumphs, the tribulations of a lot of black women all over this world," said U.S. Rep Maxine Waters, D-Calif.

"It does not matter who sang `At Last' before or after Etta. It does not matter when it was sung, or where it was sung. `At Last' was branded by Etta, the raunchy diva ? that's her signature and we will always remember her."

James won four Grammy Awards, including a lifetime achievement honor and was inducted in the Rock and Roll Hall of Fame in 1993. In her decades-long career, she became revered for her passionate, soulful singing voice.

She scored her first hit when she was just a teenager with the suggestive "Roll With Me, Henry," which had to be changed to "The Wallflower" in order to get airplay. Her 1967 album, "Tell Mama," became one of the most highly regarded soul albums of all time, a mix of rock and gospel music.

She rebounded from a heroin addiction to see her career surge after performing the national anthem at the 1984 Olympics in Los Angeles. She won her first Grammy Award a decade later, and two more in 2003 and 2004.

James is survived by her husband of 42 years, Artis Mills and two sons, Donto and Sametto James.

"Mom, I love you," Donto James said during brief remarks. "When I get to the gates, can you please be there for me?"

Fitch cuts Italy, Spain, other euro zone ratings (Reuters)

NEW YORK (Reuters) ? Fitch downgraded the sovereign credit ratings of Belgium, Cyprus, Italy, Slovenia and Spain on Friday, indicating there was a 1-in-2 chance of further cuts in the next two years.

In a statement, the ratings agency said the affected countries were vulnerable in the near-term to monetary and financial shocks.

"Consequently, these sovereigns do not, in Fitch's view, accrue the full benefits of the euro's reserve currency status," it said.

Fitch cut Italy's rating to A-minus from A-plus; Spain to A from AA-minus; Belgium to AA from AA-plus; Slovenia to A from AA-minus and Cyprus to BBB-minus from BBB, leaving the small island nation just one notch above junk status.

Ireland's rating of BBB-plus was affirmed.

All of the ratings were given negative outlooks.

Fitch said it had weighed up a worsening economic outlook in much of the euro zone against the European Central Bank's December move to flood the banking sector with cheap three-year money and austerity efforts by governments to curb their debts.

"Overall, today's rating actions balance the marked deterioration in the economic outlook with both the substantive policy initiatives at the national level to address macro-financial and fiscal imbalances, and the initial success of the ECB's three-year Long-Term Refinancing Operation in easing near-term sovereign and bank funding pressures," Fitch said.

Two weeks ago, Standard & Poor's downgraded the credit ratings of nine euro zone countries, stripping France and Austria of their coveted triple-A status but not EU paymaster Germany, and pushing struggling Portugal into junk territory.

With nearly half a trillion euros of ECB liquidity coursing through the financial system, some of which has apparently gone into euro zone government bonds, and with hopes of a deal to write down a slab of Greece's mountainous debt, even that sweeping ratings action had little market impact.

The euro briefly pared gains against the dollar after Fitch cut the five euro zone sovereigns but soon jumped to a session high of $1.3208, according to Reuters data, its highest since December 13.

Italy is widely seen as the tipping point for the euro zone. If it slid towards default, the whole currency project would be threatened.

Italian Prime Minister Mario Monti, a technocrat who has won plaudits for his economic reform drive, said he reacted to Fitch's downgrade of Italy with "detached serenity."

"They signal things that are not particularly new, for example, that Italy has a very high debt as a percentage of GDP and they signal that the way the euro zone is governed as a whole is not perfect and we knew that too," he said during a live interview on Italian television.

"They also say things that give a positive view of what is being done in Italy because there is much appreciation for policies of this government and this parliament," he said.

Fitch said of Italy: "A more severe rating action was forestalled by the strong commitment of the Italian government to reducing the budget deficit and to implementing structural reform as well as the significant easing of near-term financing risks as a result of the ECB's 3-year Longer-term Refinancing Operation."

Microsoft patents method for secure pairing of devices wirelessly and a 3D rangefinder camera

IBM may be the king of patents, and Apple's patent applications grace these pages rather frequently, but Microsoft's not one to rest on its IP laurels, either. A couple of newly published patents out of Redmond have made their way to the web: one for securely pairing wireless devices and one for 3D rangefinder camera technology. The pairing tech works via a direct connection between devices using Bluetooth or WiFi and an automated, two-step authentication process. First, a request is sent by an initiating handset and is authenticated by its target using an address book of recognized devices. Next, the two devices exchange encrypted security keys to cement their digital friendship, leaving you free to exchange your favorite episodes of Mystery Science Theater 3000 or latest LOLcat pictures with the greatest of ease.

Microsoft's other patent of interest is for "a 3D camera for determining distances to regions in a scene." That's not a new concept by any means, but this new bit of IP integrates all the functions of such an imager on a single chip. Essentially, it claims an image sensor, a light source to illuminate the scene being shot and a controller to gate the pixels on the sensor on and off and correct for inaccuracies caused by other light sources. It works by projecting the light source and determining the distance to various points based upon the time it takes for the light to bounce off the target and reach the camera sensor. Want to know more? You can haz all the patent particulars at the source links below.

Believing the impossible and conspiracy theories

ScienceDaily (Jan. 26, 2012) ? Distrust and paranoia about government has a long history, and the feeling that there is a conspiracy of elites can lead to suspicion for authorities and the claims they make. For some, the attraction of conspiracy theories is so strong that it leads them to endorse entirely contradictory beliefs, according to a study in the current Social Psychological and Personality Science (published by SAGE).

People who endorse conspiracy theories see authorities as fundamentally deceptive. The conviction that the "official story" is untrue can lead people to believe several alternative theories-despite contradictions among them. "Any conspiracy theory that stands in opposition to the official narrative will gain some degree of endorsement from someone who holds a conpiracist worldview," according to Michael Wood, Karen Douglas and Robbie Sutton of the University of Kent.

To see if conspiracy views were strong enough to lead to inconsistencies, the researchers asked 137 college students about the death of Princess Diana. The more people thought there "was an official campaign by the intelligence service to assassinate Diana," the more they also believed that "Diana faked her own death to retreat into isolation." Of course, Diana cannot be simultaneously dead and alive.

The researchers wanted to know if the contradictory beliefs were due to suspicion of authorities, so they asked 102 college students about the death of Osama bin Laden (OBL). People who believed that "when the raid took place, OBL was already dead," were significantly more likely to also believe that "OBL is still alive." Since bin Laden is not Schr?dinger's cat, he must either be alive or dead. The researchers found that the belief that the "actions of the Obama administration indicate that they are hiding some important or damaging piece of information about the raid" was responsible for the connection between the two conspiracy theories. Conspiracy belief is so potent that it will lead to belief in completely inconsistent ideas.

"For conspiracy theorists, those in power are seen as deceptive-even malevolent-and so any official explanation is at a disadvantage, and any alternative explanation is more credible from the start," said the authors. It is no surprise that fear, mistrust, and even paranoia can lead to muddled thinking; when distrust is engaged, careful reasoning can coast on by. "Believing Osama is still alive," they write, 'is no obstacle to believing that he has been dead for years."

Guarded Optimism for Some Iowans After Obama's Address (ContributorNetwork)

Here are Iowans' thoughts on Barack Obama's 2012 State of the Union address on Tuesday:

"I felt optimistic after hearing President Obama's State of the Union address last night. I applaud Obama for telling the Congress that they need to pass bills to help the American people and the need of the government to tight their belts was refreshing. I'm definitely tired of the rich feeling run the country. Obama has presented himself as being the president of the people not the president of the rich." -- Tylor Hoodjer, welder, Cedar Falls

"I was very impressed with Obama's State of the Union address. I looked forward to hearing him speak and telling the American citizens how he felt the country was fairing. Listening to his words, I noted that he has swung more on the conservative side using bipartisanship as the reason. To me, this is simply meeting in the middle on issues that directly affect the working class. Obama's statement about the worst of the recession is now over is a statement I feel he should re-evaluate. Living in the Midwest, I definitely feel we are still in a full blown recession. I'm still looking for the day that jobs are easy to find and then land." -- Brittney Harms, manager, Ackley

"I have been listening to the Republican stand on many issues. This includes Ron Paul's campaign platform to eliminate five government entities. I heard President Obama state that the government must tighten their belts to help reduce the national deficit. This was a good statement but I did not hear specifics on how he plans on doing that. Obama proposed to freeze annual domestic spending over the next five years. This is all fine and good but in freezing spending cuts need to be made. I would like to hear a solid plan on how this is to be accomplished." -- Debra Kurth, secretary, Ackley

"I would like to applaud President Obama for an excellent State of the Union address. Solid statements were made within the speech on how the American people have sustained themselves over the last several hard years. I also heard President Obama state that he will sign solid bills that the Congress passes. I am extremely upset with the stonewalling the Congress has done on critical issues over the past three years that would have helped the American people." -- Claudia Campbell, scheduler, Cedar Falls

"I happened to listen to part of the State of the Union address and felt Obama did a nice job in speaking but I was not impressed with his speech. It is time that Obama gets off his duff and gets angry with the Congress. Isn't it time that the government must stay within their budget. I'm so tired of hearing about the national deficit it isn't funny. I just want to live happily without struggling week to week." -- Norm Houston, self-employed, Eldora

J.C. Penney gets rid of hundreds of sales (AP)

NEW YORK ? J.C. Penney is permanently marking down all of its merchandise by at least 40 percent so shoppers will no longer have to wait for a sale to get the lowest prices in its stores.

Penney said Wednesday that it is getting rid of the hundreds of sales it offers each year in favor of a simpler approach to pricing. On Feb. 1, the retailer is rolling out a three-tiered strategy that offers "Every Day" low pricing daily, "Monthly Value" discounts on select merchandise each month and clearance deals called "Best Price" during the first and the third Friday of each month when many shoppers get paid.

The plan is similar to Wal-Mart Store Inc.'s iconic everyday low pricing strategy except that Penney's goal isn't to undercut competitors. Instead, Penney aims to take the guesswork out of shopping in its stores by offering customers fewer sales and more predictable pricing.

Penney's plan comes at a time when stores are struggling to wean shoppers off the profit-busting bargains that they have come to expect in the weak economy. The move is risky because shoppers who love to bargain-hunt may be turned off by the absence of sales.

"The big question on investors' minds will be how customers will react to a single price point versus a perceived discount under the old strategy," says Citi Investment Research analyst Deborah L. Weinswig.

Here's how Penney's pricing will be different:

? Sale prices become everyday prices. The company will use sales data from last year to slash prices on all merchandise at least 40 percent or lower than the previous year's prices. So, a woman's St. John's Bay blouse regularly priced at $14.99 could have the "Every Day" price of $7.

? Fewer sales. The retailer will pick items to go on sale each month for a "Monthly Value." For instance, in February, it might be jewelry for Valentine's Day and in December it could be Christmas decorations. Items that don't sell well would go on clearance and be tagged "Best Price," signaling to customers that's the cheapest price.

? New tags. The retailer used to pile stickers on price tags to indicate each time an item was marked down. But now each time an item gets a new price, it gets a new tag too. A red tag indicates an "Every Day" price, a white tag a "Monthly Value" and a blue tag a "Best Price."

? Simpler pricing. Penney will use whole figures when pricing items. In other words, you won't see jeans with a price tag of $19.99, but rather $20.

? New advertising. There will be an ad that shows shoppers screaming "No" to discounts as they look in their mailboxes, a pile of coupons and big sales signs. A 96-page colorful catalog that highlights "Monthly Value" items will be mailed each month to 14 million customers, along with other promotional efforts.

The new strategy, unveiled at Penney's investor meeting on Wednesday, comes as the retailer tries to turn around its business. Heavy discounting has hurt department stores like Penney. The group generates an average of about $200 per square foot, less than half the $550 or $600 stores like Victoria's Secret and Lululemon generate per square foot, according to John Bemis, head of Jones Lang LaSalle Inc.'s retail leasing team.

Penney has been a laggard even among department stores as its core middle-class customers have been among the hardest hit by the weak economy. It's also failed to attract a younger, hip customer despite its efforts to add brands Mary Kate and Ashley Olsen teen clothing collection. And its stores are described by some in the industry as "boring."

For the first nine months of fiscal 2011, Penney's revenue at stores opened at least a year ? an indicator of a retailer's health ? rose 0.9 percent, while competitors like Macy's Inc. rose 5.4 percent, and Kohl's was up 1.1 percent. Penney posted a loss in the third quarter and cut its fourth-quarter earnings outlook after a disappointing holiday season when it had to heavily discount to attract consumers. Penney's gross profit margin has shrunk for six straight quarters.

The pricing strategy caps months of speculation about what Penney's future might look like under the leadership of Ron Johnson, a former Target Corp executive and the mastermind behind the success at Apple Inc. stores who became Penney's CEO in November.

Johnson, who joined the company's board in August, has begun to put his stamp on the retailer. Penney announced in December it will have homemaker doyenne Martha Stewart develop mini-shops starting next year. And Johnson has tapped former colleagues at Apple and Target to join him at Penney.

Johnson and his management team have a big task ahead of them in making the new pricing strategy appeal to shoppers. For years, Penney, like many other stores, has artificially propped up ticketed prices even as costs have come down slightly over the past decade. The intent: to make it look like shoppers are getting great discounts.

Penney has been an especially big promoter. Last year, the company, which offered 590 sales events last year, had about 72 percent of its revenue come from merchandise that was discounted by 50 percent or more.

That's more than double the industry average. According to an estimate by management consultant firm A.T. Kearney, a typical retailer sells between 40 and 45 percent of its inventory at a promotional price, up from 15 to 20 percent 10 years ago.

The increased discounting has been a vicious cycle that only feeds into shoppers' insatiable appetite for bigger and better discounts. In fact, whereas it took 38 percent off to get shoppers to buy 10 years ago, it now takes discounts of 60 percent, Penney says.

At Penney, the regular price on an item that costs $10 to make rose 43 percent, from $28 in 2002 to $40 in 2011. But because of all of its sales and other promotions, what it actually ended up selling for rose only 15 cents, from $15.80 to $15.95 during that same period.

Charles Grom, a retail analyst at J.P. Morgan, said it will be difficult to change shoppers' buying habits. Macy's, for example, cut back on coupons a few years ago, only being forced to ramp it back up after seeing sales suffer.

"Shopper fatigue has been building for several years with the advent of the Internet and the ability for shoppers to compare prices," he said. "If (Johnson) can try to pull this off, it will be impressive. But it's hard for retailers to change the image of the company. He has a lot of wood to chop."

Mild cognitive impairment is common, affects men most, study finds

ScienceDaily (Jan. 25, 2012) ? Researchers involved in the Mayo Clinic Study of Aging report that more than 6 percent of Americans age 70 to 89 develop mild cognitive impairment (MCI) every year. Also, the condition appears to affect men and those who only have a high school education more than women and those who have completed some higher education. People with MCI are at the stage between suffering the normal forgetfulness associated with aging and developing dementia, such as that caused by Alzheimer's disease.

The study -- published in the Jan. 25, 2012, issue of Neurology, the medical journal of the American Academy of Neurology -- reports that 296 of the 1,450 study participants developed MCI, an incidence rate of 6.4 percent per year overall. Among men, the incidence rate was 7.2 percent, compared with 5.7 percent per year for women.

"While incidence rates for MCI have been reported previously, ours is one of the few studies designed specifically to measure the incidence of MCI and its subtypes using published criteria," says lead author Rosebud O. Roberts, M.B., Ch.B., of the Mayo Clinic Division of Epidemiology. "The statistically significant difference between incidence rates among men and women represents an important finding for those evaluating patients for MCI."

The study also looked in more detail at patients with MCI, dividing them according to whether they developed amnestic MCI (aMCI) -- in which the condition affects the memory domain -- or non-amnestic MCI (naMCI).

Similar to the overall results, the incidence rates for aMCI and naMCI were higher in men than in women. In addition, the study found that individuals with only a high school education developed either aMCI or naMCI at a higher rate than those with some higher education.

"Understanding the distribution of incident MCI by age, sex and other demographic variables is critical to helping us understand the cause of the condition, as well as how to prevent MCI and its progression to full-blown, irreversible dementia," Dr. Roberts says. "This study advances our understanding of MCI and will help clinicians provide even better care for their patients, especially during initial evaluations."

About Mild Cognitive Impairment

People with MCI have mild problems with thinking and memory that do not interfere with everyday activities, although their forgetfulness is often apparent to them and their friends and family. While not everyone with MCI develops dementia, an estimated 5 to 10 percent do.

Symptoms of MCI include:

  • Difficulty learning and remembering new information
  • Difficulty solving problems or making decisions
  • Forgetting recent events or conversations
  • Taking longer to perform complex or difficult mental activities.

Saving the snow leopard with stem cells

ScienceDaily (Jan. 23, 2012) ? The survival of the endangered snow leopard is looking promising thanks to Monash University scientists who have, for the first time, produced embryonic stem-like cells from the tissue of an adult leopard.

Never before have induced pluripotent stem (iPS) cells, which share many of the useful properties of embryonic stem cells, been generated from a member of the cat family. The breakthrough raises the possibility of cryopreservation of genetic material for future cloning and other assisted reproduction techniques.

The study, published in Theriogenology, is part of the PhD project of Rajneesh Verma, supervised by Dr Paul Verma, both from the Monash Institute of Medical Research (MIMR). Associate Professor Peter Temple-Smith of Monash University's Department of Obstetrics and Gynaecology and Professor Michael Holland of the University of Queensland also collaborated.

The researchers used ear tissue samples taken from adult snow leopards at Mogo Zoo, in NSW, to generate the iPS cells.

Dr Verma said the breakthrough was significant due to the difficulty of obtaining reproductive cells, or gametes, even from animals in captivity.

"There is a lot of interest in cryopreservation of tissue from endangered species, but for this to be useful for conservation, both sperm and an egg are required."

"The power of stem cells is that they can differentiate into all the cell types in the body. This means, they have the potential to become gametes. In fact, mouse iPS cells have given rise to entire off-spring, so the possibilities are enormous," Dr Verma said.

Mr Verma said the benefits of the breakthrough for the conservation of cat species, and biodiversity were clear.

"By generating these stem cells, we've taken the first step in creating reproductive cells from adult tissues of an endangered animal. In the future, we aim to harness the potential of the iPS cells and create off-spring. This would help save species from extinction," Mr Verma said.

The snow leopard is a large cat native to the mountain ranges of Central Asia. Their high-altitude habitat and shy nature make accurate population counts difficult, but it is estimated that between 3500 and 7000 snow leopards exist in the wild, with numbers on the decline.

Mr Verma said he became fascinated with large cats during his childhood in India.

"I'm really following my passion in applying my expertise in stem cells to help save these animals. I am applying the same techniques to other members of cat family, including the Bengal tiger, the jaguar and the serval."

"Mad Men" shocker: could Don and Betty reunite? (Reuters)

LOS ANGELES (TheWrap.com) ? Don and Betty Draper, together again?

That's a hint "Mad Men" series creator Matt Weiner is dropping about the show's upcoming fifth season, which premieres on AMC on March 25.

"It's called 'A Little Kiss,'" Weiner tells TV Guide of the two-hour season premiere. "I like the title to have some kind of synergy with the show so it will pique your interest."

Asked if Jon Hamm's Don Draper is one half of the titular kiss, perhaps with secretary-turned-fianc?e Megan (Jessica Par?), Weiner answered with a cryptic comment that could mean a surprise reunion for exes Don and Betty (January Jones).

"Who says Megan's even going to be part of Don's life?" Weiner told the magazine. "He may be back with Betty. One of my favorite scenes from (the season-four finale) was when Betty offered herself to him again. And let's face it -- those two look really good together."

AMC did not immediately respond to TheWrap's request for comment.

100% A Separation

All Critics (63) | Top Critics (20) | Fresh (64) | Rotten (0) | DVD (2)

The film wraps us, with stunning directness, in the complex folds of its characters' passions.

A Separation is not the work of a constrained artist. It's a great movie in which the full range of human interaction seems to play itself out before our eyes.

The miracle of A Separation is that it doesn't spare any of its characters, nor does it seek to indict them. It is a democratic portrait of a theocratic world.

Tensely involving Iranian drama with niche potential.

Tense and narratively complex, formally dense and morally challenging.

A constant surprise, a film that captures the drama and suspense of real life as urgently as any picture released this year.

The audience is rocked back and forth in sympathy. . . in a tangled predicament. [N]one is one-dimensional in the superb ensemble [as] the point of view changes by minutes.

Farhadi's true focus is the flawed capacity for any law -- any form of cold rationality, period -- to address the slippery nature of human affairs. It's a frantic microcosm of life itself.

So much fun to watch that you could very nearly miss the important fact that it is also as piercing a critique of Iranian society as that country has produced in some time.

There are no heroes or villains in this story: there are only everyday figures who try their best and struggle to survive.

One of the year's most engrossing films, directed by Asghar Farhadi from his richly layered screenplay (some advice: pay particular attention to what occurs in the sequence following the opening credits)

It has an external layer that comments upon Iran's complex and seemingly unfair divorce system, as well as other social customs, but underneath it's not much more than a standard potboiler.

Facebook aids organ donation

HERE'S another reason to join the social media site Facebook: it's a great place to find a kidney.

Between the children's photos and reminiscences about high school, more and more pleas for help from people with failing kidneys are popping up.

Facebook and other social media sites are quickly becoming a go-to place to find a generous person with a kidney to spare, according to the people asking for help and some national organisations that facilitate matches.

Damon Brown found a kidney on Facebook after telling his story on a special page the Seattle dad created under the name, "Damon Kidney".

His friends and family forwarded the link to everyone they knew and on January 3 a woman his wife has known for years, but not someone they consider a close family friend, will be giving him a kidney.

"She said it wasn't really for me. It was for my kids, because they deserve to have a dad around," Mr Brown, 38, said.

Mr Brown's story is not unique. This past year, a man in Michigan also found a kidney donor through Facebook, and a Florida woman found one through Craigslist.

In 2007, Woodbridge mother of three Michelle Eather gave her kidney to American businessman Ronnie Andrews, whom she met on the internet.

Damon Brown admits he was a little embarrassed to ask for help so publicly. Except for telling close friends and family, the Seattle father of two young boys had been keeping his illness pretty quiet.

He was on the official transplant list and had started mobile dialysis but was seeing his health deteriorate.

After one particularly difficult visit with his doctor, Damon and his wife, Bethany, decided to create the Facebook page, which has attracted more than 1400 friends.

Jacqueline Ryall, 45, said she felt a need to donate a kidney to Mr Brown to give back her own good health and all she has been given. She's not a mother and gushed about how beautiful Damon and Bethany's kids are.

"The real reason I'm doing this is he's got kids and he's a good guy," she said

"My life is in a good place. I've been given lots and I have a responsibility to give back."

After some research, Ms Ryall decided it's relatively safe for a woman in good health to donate a kidney.

If something is going to go wrong with her own kidneys, she has heard they usually fail in twos.

"Right now it feels like absolutely the right thing to do," she said, adding that she hopes her decision will help make other people less afraid to do the same thing.

Instantly Turn Video Clips Into Movies With V.I.K.T.O.R (Mashable)

The Spark of Genius Series highlights a unique feature of startups and is made possible by Microsoft BizSpark. If you would like to have your startup considered for inclusion, please see the details here. Name: V.I.K.T.O.R.

[More from Mashable: Shoutz Connects You to the World, One 15-Second Video at a Time]

Quick Pitch: V.I.K.T.O.R. is an automatic video-editing app.

Genius Idea: The free iPhone app makes movie making and sharing mobile clips quick and easy.

[More from Mashable: Jewelry Site Plukka Turns Group Buying On Its Head]

Built-in cameras on smartphone and tablet devices make it easy to record videos of experiences anywhere we go. But how often do we go back to watch these videos or share them?

V.I.K.T.O.R., an automatic video-editing app, provides a simple and convenient way to cut and edit video clips and turn them into short movies. The app allows users to make short movies -- either 20 seconds, one minute or two minutes long -- that actually look professionally edited. For now, it's free to create a movie, but in the future, the company plans to charge $0.99 for 1-minute movies and $1.99 for two-minute movies.

"We all have special moments that we want to remember," Evgenia Bogdanovich, co-founder of V.I.K.T.O.R., told Mashable. "This video editing app offers a way to recollect your memories and turn them into a video presentation that feels emotional and looks professional."

Developed in June, the idea of V.I.K.T.O.R. was inspired while two of the four co-founders of the app were traveling in Hong Kong. Sergey Nurmamed and Alexander Didenko saw tourists taking pictures and recording videos with their phones, and wondered how often people actually go back and look at these memories. When Nurmamed and Didenko returned to Russia, the V.I.K.T.O.R. team decided to create an automatic-editing app to make it easier for people to create movies from their experiences and share them with friends and family.

To start making mini-movies, download the app onto an iPhone and choose one of the following video-editing options:

  • Automatic: The app randomly chooses video footage from your phone.
  • Semiautomatic: Users manually select videos.
  • Controlled: Gives users more control by allowing them to sort their videos by different sections and shots After you select an option, users can also add in their own themes and soundtracks. Browse the list of categories (travels, sports, family, events, lifestyle or moods) and select a theme that suits your movie. Then create a movie title and select the mobile clips that you want to include.
    Select an unlimited number of video clips to include in your movie.

    Finally, click the "Magic Up!" button to see your own personal edited movie and instantly share it on Facebook, YouTube or via email.

    Hit the "Magic Up!" button to see your personal mini movie.

    "V.I.K.T.O.R. is a new way of communication because it makes it easier to have a presentation of your experiences to share with your friends and relatives," says Bogdanovich. "Sharing your own movie is much more emotional than sharing a photo."

    Unlike video sharing site TwitVid, V.I.K.T.O.R. automatically edits your videos, does not allow you to include your own songs in the soundtrack and does not have an option to directly share your videos to Twitter.

    V.I.K.T.O.R. currently has over 400 users and will soon be available for Android devices.

    1983 Apple prototype pictures show iPhone ancestor (Digital Trends)

    phone 2Here?s a nice little bit of Apple trivia for you. Apple?s first touchscreen technically wasn?t the 2007 launched iPhone. The company had apparently designed a prototype of a touchscreen?landline phone back in the 1980s.

    It?s an interesting look into the early game plan which eventually gave birth to the iPhone. The all-white stationary device?s point of origin seems to be 1983. It features a stylus to interact with the built-in screen, and one of the pictures shows off some sort of accounting and check-writing application; possibly using a modem to pay bills.

    The phone prototype never made it into production, but it was supposedly designed by Harmtut Esslinger. The German-American Esslinger is the guy behind the Apple IIc, which was the company?s first push towards a portable computer. The 1983 touchscreen phone definitely has some of the Apple design elements from that period. Hartmut Esslinger later went on to found a company called Frogdesign.apple phone prototype

    Mashable points out that this actually isn?t the first time these pictures have been passed around the Internet. However, interest in the old prototypes has been renewed thanks to a peek at the Stanford University stockpile of Apple documents, which had previously been locked away. These archives were donated to Stanford back in 1997 when Jobs returned to the company after being forced out.

    Apparently there are a large number of prototype?s squirreled away, some resembling Apple?s current products. There?s even a device that looks like a tablet. It would be great to see a museum documenting the trail of Apple?s cast-off ideas, given the company?s philosophy of simplicity. Hopefully Stanford opens up the collection to the public at some point.
