(CNN) -- The mainstream media -- you know who you are -- are rooting for immigration reform.

They like the idea of doing something to accommodate the country's 11 million undocumented immigrants, who, despite conservative rhetoric to the contrary, were never going to be banished.

They swoon over the kind of bipartisanship that brings together John McCain and Marco Rubio on the one hand and Barack Obama and Chuck Schumer on the other.

They believe the Republican Party needs to moderate its harsh rhetoric about immigrants -- if only to salvage its political future -- and are welcoming the GOP's new realism.

But is that enthusiasm causing media organizations to overestimate the prospects for reform?

Any bill still must pass the Republican House, which has been a graveyard for numerous Obama reforms. The Senate has always been a place where top lawmakers reach across the aisle more easily than in the polarized House, as was evident during the fiscal cliff debacle. And there are conservative groups determined to derail any path toward citizenship, which they view as amnesty.

It's not that journalists are acting as cheerleaders for the emerging plan. But when the media have qualms about an issue, they couch it as being "controversial" and "risky" (say, George W. Bush's plan to privatize Social Security).

Opinion: Immigrant - Can we trust Obama?

By contrast, look at the way the president's immigration speech in Las Vegas was covered:

The New York Times: "Seizing on a groundswell of support for rewriting the nation's immigration laws ..."

The Washington Post: "Obama added to momentum on Capitol Hill in favor of an overhaul of the nation's immigration laws ..."

We saw the same supportive approach when the Pentagon lifted a ban on women serving in front-line combat positions, which, despite some conservative opposition, was greeted with favorable features that largely depicted the move as long overdue.

Watch: Should N.Y. Times Have Censored Company Name Over the S-Word?

As with many perpetual Beltway disputes, the contours of a common-sense compromise on immigration have been clear for some time. The right wants tougher border enforcement and employer verification procedures. The left wants undocumented immigrants taken out of the "shadows," as Obama put it, and given a chance to become openly productive members of society.

The key are the tradeoffs. How long would a path to citizenship take? Are fines and back taxes required? How do we ensure that those who broke the law don't get an unfair advantage over legal applicants?

I don't argue with the standard political analysis that the moment may be ripe for immigration reform.

Watch: Media Seize on Emotional Moment of Gabby Giffords' Testimony

Mitt Romney, who talked about wanting immigrants to "self-deport," got clobbered among Hispanic voters. The GOP has lost the popular vote in five of the past six presidential elections. Sean Hannity, the Fox News commentator, says he has "evolved" on the issue, and he's not alone.

The conservative media may be a bellwether here. After Obama's Tuesday speech, Hannity's leadoff guest was Karl Rove, the former Bush lieutenant who favors the Senate compromise. And when Rubio, the Florida senator and son of Cuban immigrants, called in to Rush Limbaugh's show, the host -- while criticizing Obama -- told him, "What you are doing is admirable and noteworthy. You are recognizing reality."

But illegal immigration remains a divisive subject that still arouses visceral opposition among some Americans. Capitol Hill is a place where partisan maneuvering can push the government to the brink of default. And as George W. Bush learned in his second term, hammering out a compromise on such a volatile issue is maddeningly elusive.

Perhaps the election changed the landscape and both parties will find a way to compromise. In the meantime, it might be wise to take the upbeat media coverage with a healthy dose of skepticism.

A*STAR scientists solve century-old mystery in yeast infections

SINGAPORE: Scientists from the Agency for Science Technology And Research (A*STAR) have solved a century-old mystery in yeast infections.

They constructed stable strains of Candida albicans, the most prevalent human fungal pathogen and a major cause of hospital acquired infection.

A*STAR said on Friday that their discovery will help pave the way to develop drugs that effectively target and treat such infections.

Currently, the choice of drugs for this pathogen is limited.

Drugs resistance has also emerged worldwide, posing a great challenge to medicine.

The A*STAR scientists have shown that Candida albicans, long thought of as always having two copies of each chromosome and no sexual reproduction in its life, can and does exist as a sexually reproducing cell carrying only one copy of its genome.

The discovery fills a long missing gap in the life cycle of the pathogen and greatly advances the understanding of how it generates genetic variations.

The tools developed will help speed up the analyses of gene function and might speed up efforts to cure Candida infections.

At least 25 killed in Mexico office blast, dozens injured

STORY HIGHLIGHTS

• NEW: 25 people were killed and more than 100 are injured, interior minister says


• The explosion collapsed two floors of an office building, paramedics say


• Rescuers have pulled a survivor from the rubble, Mexico's president says


• Crews are searching for people trapped in the building

Mexico City (CNN) -- An explosion rocked the offices of Mexico's state oil company Thursday, killing at least 25 people and injuring 101, Mexico's interior minister said.

Dozens of people were trapped in the building after the explosion, Foro TV reported. It was unclear how many of them had been pulled to safety, or whether anyone remained stuck inside late Thursday, Interior Minister Miguel Angel Osorio Chong told reporters.

More than five hours after the blast, rescuers had pulled at least one survivor from the rubble, Mexico's president said in a Twitter post.

Crews were still searching Thursday night for people who could be trapped in the Pemex office complex, which includes one of the city's tallest skyscrapers.

Explosion hits Mexican state oil company Pemex

HIDE CAPTION

The explosion occurred in a basement and collapsed two floors of a building adjacent to the well-known tower, said Carlos Javier Rodriguez Jurado, one of the first paramedics to arrive at the scene.

The explosion tore through the building "from the inside out," he said, and rescuers found many people trapped. Six hours after the explosion, Rodriguez said people were likely still stuck in the rubble.

It was unclear what caused the blast, and Mexico's attorney general's office is investigating, Pemex said in a statement.

A large plume of smoke rose near the building after the explosion around 4 p.m. Thursday, and emergency crews swarmed the scene.

"People were screaming. ... You could see pieces of the wall falling to the ground," said Joaquin Borrell Valenzuela, an attorney for the Pemex comptroller's office, who was in a courtyard outside the building at the time of the blast.

Paramedics quickly arrived and started pulling bodies from the rubble.

"Entering the building, we smelled a strong odor of gas," said Christopher Rangel, a paramedic and firefighter.

Outside the building, frantic family members searched for loved ones, and shaken witnesses described the explosion.

Mario Guzman said he was on the 10th floor of the tower when he felt "a very strong blow."

"We felt like the whole building was going to collapse," he told CNNMexico.

Images from the scene showed emergency rescue teams carrying people on stretchers. Authorities said helicopters carried some of the wounded to hospitals.

At least 14 people were hospitalized with injuries, and two of them were in serious condition, the state-run Notimex news agency reported.

Mexican President Enrique Pena Nieto surveyed the damage Thursday night, along with Osorio Chong and Mexico City's mayor.

Pena Nieto cautioned against speculating over what caused the blast, and said authorities would be closely investigating.

Thousands of people work at the Pemex headquarters, which includes a 54-story building that is nearly 700 feet tall.

The explosion occurred in an annex building just to the east of the tower, Foreign Minister Jose Antonio Meade said.

Officials evacuated the complex and operations will cease there until further notice, the company said.

The state oil company's director, who was on a business trip in South Korea this week, said in a Twitter post that he would return to Mexico immediately.

"We will get to the bottom of the causes in close coordination with the authorities," Pemex Director General Emilio Lozoya Austin said. "At this time, attending to the injured is the priority."

Federal troops and rescue dogs were aiding in search efforts late Thursday night.

As they combed through the rubble, a Pemex executive's cell phone rang, Rangel said.

A man on the other end of the line said he was still trapped, and started to describe his location to rescuers.

"Unfortunately, we lost communication with him," Rangel said.

When they called back, his phone didn't ring.

Alaska Airlines plane lands safely after pilot passes out

Updated 3 a.m. EST

PORTLAND, Ore. An Alaska Airlines jetliner bound for Seattle made an emergency landing in Portland, Ore., Thursday night after the pilot lost consciousness, an airline spokesman said.

The co-pilot landed Flight 473 safely after declaring an emergency to get priority care for the pilot, spokesman Paul McElroy said. All of the airlines' pilots are trained to fly single-handedly.

The pilot lost consciousness "somewhere over Oregon," McElroy said, then later regained consciousness and left the cockpit. A doctor on board the flight tended to him in the cabin until the plane landed and was met by medical personnel on the runway.

The pilot, who was not identified, was taken to a hospital but there was no immediate word on his condition, McElroy said.

The Boeing 737-700, with 116 passengers and five crew members on board, left Los Angeles about 6:30 p.m. and was diverted to Portland, touching down there at about 9 p.m., reports CBS Portland affiliate KOIN-TV. It had been due to arrive in Seattle at 9:30 p.m.

McElroy says the pilot has been flying for Alaska for 28 years and was current on his six-month medical evaluation. The co-pilot is an 11-year Alaska Air veteran.

On Jan. 22, the co-pilot on an Alaska Airlines flight from Seattle to Las Vegas fainted briefly, and the pilot requested emergency landing priority to get prompt medical assistance for him.

"At this point, we do not believe there was a connection between the two incidents," McElvoy said.

Twenty passengers with a tight schedule for connecting flights were put on a Horizon Air shuttle flight to Seattle on Thursday night, the spokesman said.

A new pilot was dispatched to Portland to fly the remaining passengers to Seattle on board the same plane.

Arias' Lawyer Shows Ex-Boyfriend's Lewd Photos

Accused murderer Jodi Arias was kept away from the Mormon friends of her lover Travis Alexander and their torrid sex affair was kept secret by Alexander, even as he sent lewd photos of himself to her online, according to court testimony today.

The testimony in Arias' trial for killing Alexander in 2008 was intended to bolster the defense's argument that she killed him in self defense, that Alexander was a sexual deviant who treated Arias as his "dirty little secret."

Arias' attorneys introduced as evidence photos that Alexander took of his penis and sent to Arias, part of a string of graphic messages and sexual phone calls the two engaged in while Alexander, an elder in the Mormon church, was supposed to be chaste.

Today's witness was the latest in a string called by the defense, including Alexander's former girlfriend Lisa Daidone, who told the court that Alexander had professed to be a virgin.

Daniel Freeman continued his testimony today, describing how he was a friend of both Arias and Alexander but that Alexander kept Arias distanced from his Mormon pals.

"Travis had made more friends at (the Mormon) ward, and had (Ultimate Fighting Championship) fight nights at his house many times, and Jodi was in town, but she wasn't there," Freeman said.

"There was that group of friends, them and Jodi, two different groups, and so Lisa [Daidone] and friends from church were there, but Jodi wasn't there," Freeman said.

Alexander's behavior, the defense hopes to prove, shows that he mistreated Arias.

Arias, 32, is on trial for murdering Alexander, whom she dated for a year and continued to have a sexual relationship for a year after that. Her attorneys claim that Alexander was abusive and controlling toward Arias, and that she was forced to kill him.

Freeman described how he took a trip with his sister, Alexander, and Arias, and how Alexander had asked him to come along so that he and Arias "would not get physical."

"I don't know that I can say he didn't want to be alone with her, but he liked that when I was there, and my sister was there. They weren't as physical," Freeman said.

Freeman admitted that he had no idea Alexander and Arias had been having a sexual relationship the entire time they were together. He said Alexander never mentioned that to his friends.

In fact, Freeman noted that Alexander was considered to be a church elder when he baptized Arias into the Church of Latter-Day Saints. Both a church elder and a convert were expected to abide by the church's strict law of chastity, which banned any sexual relations outside of marriage.

"One thing people give up in this baptism process was sex," prosecutor Juan Martinez said. "Did you know she was having oral sex with Mr. Alexander at the time of her baptism? Would that be an insincere baptism?"

"She would not be ready to be baptized in that case," Freeman said.

"You were asked about Miss Arias, whether she was worthy of baptism if she was performing oral sex, but what about the elder receiving oral sex?" defense attorney Kirk Nurmi said.

"They would not be worthy of performing that ordinance at that time until they had gone through repentance," Freeman said. "They would go to a discipline council and could face excommunication or a probation period or have their priesthood removed."

Freeman said that Alexander never confessed to having a sexual relationship with Arias.

Freeman's testimony came on the third day of the defense's attempt to paint Alexander as a controlling, sex-obsessed liar who was cruel to Arias. Other witnesses have said that Alexander cheated on other women he dated with Arias, and lied to his friends and family about their relationship.

The defense also had Freeman point out that Alexander was strong and fit. They are expected to conclude that Alexander was physically threatening Arias when she killed him.

BlackBerry must remember strengths

STORY HIGHLIGHTS

• BlackBerry sales have slumped in the U.S. but is still strong in emerging markets


• New models launched should remember why they are popular in developing world


• In places like Brazil and South Africa, the 10 is the update to their current phone


• in Sub-Saharan Africa there is expected to be 175 million new customers in the next 3 years

Watch Jim Clancy on CNN International's "The Brief" at 4p.m. ET GMT Friday.

(CNN) -- BlackBerry's loss of market share in the U.S. is the stuff of legends. Last fall, it was estimated only about 2% of American phone users were still carrying their BlackBerry mobile with its iconic keypad.

But consider this: sub-Saharan Africa is expected to add 175 million new mobile users in just the coming 3 years. That's according to the GSMA, which represents the world's mobile operators.

"Mobile has already revolutionized African society and yet demand still continues to grow by almost 50 percent a year," said Tom Phillips, Chief Government and Regulatory Affairs Officer, GSMA.

That could be good news indeed for BlackBerry. Research in Motion, the maker of BlackBerry, estimates it holds a 70% market share in countries like South Africa.

The company's new phones, announced this week, are not the ones some of its best customers in emerging markets would like to buy. They're too expensive. But Research in Motion -- which also this week changed its company name to BlackBerry -- is pledging some of its six new models will address that.

While millions in China, Europe and the U.S. have adopted Android or iOS smartphones with a vengeance, millions more users in emerging markets are enthused about what's in store for the new BlackBerry 10. It's the update for what many of them are already using.

They live in countries like Brazil, Malaysia, Nigeria, Kenya and South Africa. They have embraced the BlackBerry for a combination of factors that all point to the different way mobile devices are used.

Unlike their counterparts in Europe and America, the mobile in their pocket is more likely to be their primary link to the internet.

BlackBerry Messenger is the connection that allows these users unlimited conversations without paying charges for SMS data. While young, brand-conscious Chinese may be willing to part with several months' salary to buy the latest iPhone, African users are looking for more practical (and cheaper) connections.

What separates developed countries from their developing counterparts at street level can be summed up in a single word: infrastructure.

Isobel Coleman, senior fellow and Director of the Civil Society, Markets and Democracy Initiative at the Council on Foreign Relations, says mobile technology has proved it can bridge the gap where infrastructure is lacking.

"It's a culture, it's an economy, it's innovation, education, healthcare, it's all of these things," says Coleman.

You can take that to the bank. For many Africans, their cell phone account is the first bank account they've ever owned.

In emerging markets, mobile phone banking is growing because of the lack of infrastructure. Fewer bank branches often mean long distances to travel and long lines once you've arrived.

Africans are expected to transfer more than $200 billion per year or 18% of the continent's GDP by 2015.

Oh, and that keyboard. No matter where you are in the world, there will always be a demand for a keyboard that clicks. The company appears to understand that as BlackBerry 10 models come with both soft keypads and the traditional BlackBerry buttons.

I asked some of my Twitter followers to weigh in on the BlackBerry 10 roll out. While some said Android or Apple's iOS were in their future plans, many others expressed continued enthusiasm for the BlackBerry.

Soji, a pianist and teacher in Nigeria tweeted back "I'm falling in love with this BB. Cheaper to own."

From Kuala Lumpur, Amir wrote "I need a physical keyboard to type while also having a touch-screen for photos etc. Security factor also important."

Hans-Eric from South Africa reinforced the sentiments of many mobile users in emerging markets: "The cost of data is simply too high without it (BlackBerry.)"

The voices from emerging markets couldn't have been clearer. What they expect from BlackBerry 10 is a stronger, longer lasting battery, durability and continued low cost connectivity.

CFR's Coleman agrees that BlackBerry (and anyone else) trying to win and hold this mobile device sector has to understand how these devices are being used and give the customers what they want.

"Cheap. Rugged. Not too many bells and whistles. Practical."

There is little doubt smartphones are changing the way people use the internet, how they bank, shop and interact socially.

But it's worth keeping in perspective that in a world where there are now an estimated 1 billion smartphones, there are 5 billion feature phone users. That's a lot of upside growth potential for BlackBerry and all the other players out there.

SK Group head gets four-year jail sentence

SEOUL: The head of South Korea's third largest conglomerate, the SK Group, was sentenced to four years in prison on Thursday after being convicted of embezzling close to $50 million.

The custodial sentence was seen as relatively tough in a country where convicted business tycoons are often given suspended prison terms in recognition of their apparent contribution to the national economy.

The court ruled that Chey Tae-Won, 53, had embezzled 49.7 billion won ($45.6 million) from two affiliates and funnelled the money into a firm for investments in stock futures and options in 2008.

The SK Group boss had remained free since he was indicted a year ago.

The energy-to-telecom conglomerate, which includes top mobile carrier SK Telecom, said Chey would appeal the verdict.

It was not Chey's first conviction.

In 2003 he was sentenced to three years in prison for his role in a $1.3 billion accounting fraud. He was released after just seven months and, in 2008, was finally granted a full presidential pardon, wiping his record clean.

It is not unusual for senior executives with convictions for crimes including tax evasion and embezzlement to remain in charge of South Korea's family-dominated conglomerates.

The Seoul Central District Court said in its statement that Chey had betrayed the public trust in his group.

"He should be reproached for using subsidiaries as a tool for his crime," it said.

Chey's younger brother and group vice chairman Chey Jae-Won was acquitted on charges that he was a knowing accomplice to the embezzlement.

South Korea has a long history of pardoning powerful tycoons.

Hyundai Motor head Chung Mong-Koo, who had been convicted of embezzlement and other charges, was pardoned in 2008, and Samsung Electronics chairman Lee Kun-Hee - convicted of tax evasion - was pardoned in 2009.

STORY HIGHLIGHTS

• U.S. minesweeper has been stuck off Philippines since January 17


• Attempts to float the ship at high tide failed


• Crews are removing fuel, hazardous materials, salvageable things


• Fragile reef hosts 500 fish species, 350 coral species

(CNN) -- A 224-foot-long U.S. warship will have to be cut into smaller pieces to get it off a Philippine reef where it grounded two weeks ago, Navy officials said Wednesday.

They said that's the only way to prevent further damage to the Tubbataha Reef, a Philippine national park and UNESCO World Heritage site, where the USS Guardian, an Avenger-class mine countermeasures ship, ran aground on January 17.

Survivors mark anniversary of cruise ship grounding

Lt. Anthony Falvo, a U.S. Navy Pacific Fleet spokesman in Pearl Harbor, Hawaii, told CNN on Wednesday that Navy salvage experts are still formulating the details of how they'll cut up the 1,312-ton minesweeper.

Crews are now working to remove any hazardous materials from the vessel and will look to save anything that could still prove useful to the Navy. The ship's 15,000 gallons of diesel fuel were removed last week.

"We will strip it out beforehand. We'll work to salvage any parts that can be salvaged," Falvo said. Then the cutting will begin.

Illegal weapons seized from ship

Heavy-lift cranes are expected at the site of the grounding, about 80 miles (130 kilometers) east-southeast of Palawan Island in the Sulu Sea, in the next few days, Falvo said. The cranes will lift the pieces of the Guardian onto barges or other ships to be taken away.

Last week, the Navy said it hoped to lift the ship off the reef in its entirety. But Falvo said Wednesday that after reviewing all the alternatives, it was decided it would have to be cut up.

After it struck the reef, initial efforts to free the Guardian at high tide were unsuccessful. Its crew of 79 was evacuated to other vessels, and the ship was battered by waves that pushed it farther onto the reef, causing leaks in its wood-and-fiberglass hull.

"The ship cannot move on its own, and it is not operational," Rear Adm. Tom Carney said last week.

Stripping, cutting up and removing the Guardian from the reef could take more than a month, Falvo said Wednesday.

This isn't the first time the Navy has had to undertake such an operation, but it hasn't happened in more than 40 years. In August 1971, the supply ship USS Regulus grounded in Hong Kong harbor during Typhoon Rose, Falvo said. It took more than a month to cut that vessel up and remove it, he said. A similar operation was also conducted in 1916, he said.

As for what the loss of the Guardian, one of 14 Avenger class mine countermeasures ships in the Navy, means for the service, Falvo said it was too early to speculate. He pointed out that the vessel was in the 23rd year of its expected 30-year lifespan.

The ship cost about $61 million to build, Lt. Cmdr. James Stockman, a Navy spokesman, said last week.

As for other costs, Philippine officials said last week that the Philippines would seek compensation for damage to the reef. About 1,000 square meters (about 10,760 square feet) of it have been damaged.

"It's a damage to a world heritage site. It's a damage to our natural resources. It's a damage to an important site. We cannot but put emphasis on the importance of this reef as a heritage site," presidential spokesman Edwin Lacierda said.

Navy commander apologizes for grounding

The reef is home to a vast array of sea, air and land creatures, as well as sizable lagoons and two coral islands. About 500 species of fish and 350 species of coral can be found there, as can whales, dolphins, sharks, turtles and breeding seabirds, according to UNESCO.

The salvage operation must ensure that the reef sustains no further damage, Lacierda said.

Navy officials are still trying to determine how the Guardian ended up on the reef.

Stockman, the Navy spokesman, said last week that the U.S. National Geospatial-Intelligence Agency, which prepares the digital navigation charts used by the Navy, has reported the location of the reef was misplaced on a chart by nine miles.

"The U.S. Navy investigation will review what charts Guardian was using. While this erroneous navigation chart data is important information, no one should jump to conclusions," Stockman said. "It is critical that the U.S. Navy conduct a comprehensive investigation that assesses all the facts and circumstances surrounding the Guardian grounding."

N.Y. Times: China hacked our computers for past four months

BEIJING The New York Times says Chinese hackers repeatedly penetrated its computer networks over the past four months, stealing reporters' passwords and hunting for files on an investigation into the wealth amassed by the family of one of China's leaders.

In a report released late Wednesday, the Times said security experts hired to plug the breach tracked the attacks to China, in some cases computers identified with the Chinese military.

The newspaper reports that, "After surreptitiously tracking the intruders to study their movements and help erect better defenses to block them, The Times and computer security experts have expelled the attackers and kept them from breaking back in."

The attacks coincided with a Times investigation into how the family and relatives of Premier Wen Jiabao built a fortune worth more than $2 billion. The report says no Times customer data was compromised but that the passwords for all employees were stolen.

The newspaper adds, "The hackers tried to cloak the source of the attacks on The Times by first penetrating computers at United States universities and routing the attacks through them, said computer security experts at Mandiant, the company hired by The Times. This matches the subterfuge used in many other attacks that Mandiant has tracked to China."

Security experts say China carries out a widespread cyber-spying operation to steal secrets and intimidate critics.

No Device Eliminates Concussion Risk, Experts Say

As the long-term consequences of concussions become clearer, a cottage industry has popped up to sell athletes and worried parents products designed to mitigate risks of concussions that even helmets cannot prevent.

Despite the bold claims of some companies, however, many experts say the Holy Grail in contact sports -- a device that prevents concussions -- simply does not exist. Indeed, experts say, there is no proof that any current device significantly reduces the risk of concussions beyond the protections already provided by helmets.

"Nightline" found several products for sale online that aim to reduce the risk of concussions or even alert parents and coaches when a kid has supposedly taken a concussion-level hit. The claims the manufacturers make are often breathtakingly reassuring.

Concern about the risk of concussion is mounting at every level of the gridiron from the NFL to colleges and even high schools. Concussions are the most common injury among high school football players.

Jennifer Branin, whose son Tyler Branin is one of the stars of the Woodbridge Warriors high school football team in Irvine, Calif., said "it was scary" the first time he had a concussion.

"He had lost his balance on the field," she said. "He got up and tried to continue, but couldn't keep his balance."

Junior Seau Had Brain Disease, Researchers Say Watch Video

She said the effects of the concussion lingered, causing Tyler to miss a week of school and football practice. Even months later, he complained of difficulty concentrating in class.

Parents such as Jennifer Branin, who is president of the team's booster club, and her husband, Andy Branin, a former college football player himself, were looking for a way to support their son's desire to play football while also keeping him safe.

"He wants to play and, as a mom, you may want to put bubble-wrap around them and protect them forever, but that's not going to happen," she said.

So Jennifer Branin decided to do something. She raised money to buy the team helmet inserts by Unequal Technologies for added protection.

Unequal Technologies, one of the highest profile players in this new market, described its product explicitly on the box as "Concussion Reduction Technology," or "CRT." It is a strip of composite material including bullet-proof Kevlar that is designed to stick inside the helmet as a liner to the existing helmet pads.

Unequal Technologies uses its material in products ranging from padded sleeves to shin guards. The company counts NFL players and X-Games athletes among its fans.

On board as paid spokesmen are Philadelphia Eagles quarterback Michael Vick and James Harrison, a linebacker for the Pittsburgh Steelers. Harrison is one of the hardest-hitting guys in the NFL and said he uses Unequal Technology's liners in his helmet.

"I don't know what it's made of but it works," Harrison says in one of Unequal's promotional videos. "I really don't feel like I'm taking a risk."

Vick wasn't wearing the CRT product when he suffered a season-ending concussion in November, but he has since promised that he will be wearing it when he returns to the field next season.

Rob Vito, founder and CEO of the Kennett Square, Pa.-based company, said he worked with scientists to create a military-grade composite material that can help protect athletes from all kinds of injuries from head to toe.
