Former Massachusetts Gov. Mitt Romney and former Godfather Pizza CEO Herman Cain enter Tuesday night's CNN/Western Republican debate as the leaders of the race for the GOP presidential nomination, according to national polls.
Romney, Cain and five other candidates will participate in the debate, moderated by CNN's Anderson Cooper, starting at 8 p.m. ET at the Sands Expo and Convention Center and the Venetian Hotel and Casino in Las Vegas, Nevada. The debate will be shown on CNN, the CNN mobile apps and CNN.com/Live.
According to a CNN/ORC International poll released Monday, 26% of respondents said they are likely to support Romney, who is making his second bid for the White House. Cain was at 25%, and Romney's margin was well within the poll's sampling error. Texas Gov. Rick Perry was third, at 13%. Separately, a CNN poll of pollsĀ indicated that Romney was on top of the field at 23%, with CainĀ three points behindĀ andĀ Perry - who was a front-runner in the national polls from late August through much of September - at 14%.
Through the use of microwaves, MIT researchers have devised technology to see through walls in real time.
The radar array system, created by Gregory Charvat and John Peabody at the university's Lincoln Laboratory, sends microwave signals that bounce off objects and ultimately return radar images to a screen. The waves can even penetrate concrete walls.
Charvat said Tuesday that the project has been in the works for a while.
āIt originally started out as my dissertation, where I developed a very slow prototype,ā he said. āWhen I moved to Lincoln Lab, I teamed up with another colleague (Peabody) who was working with technology used for imaging human tissueā in medical environments such as hospitals.
Almost all of the microwaves - 99.4% - bounce off the first object they encounter, like a wall, while only 0.6% make it through to the object on the other side, creating an admittedly weak signal, Charvat said.
X-ray would be perfect for this application, but "it's ionizing radiation," too dangerous, he said. "We use microwave technology thatās about as powerful as a cellular phone, so itās very weak. So, microwaves work. Itās not ideal, but it gets the job done."
The system creates a real-time image at the speed of 10.8 frames a second, according to the MIT website.
But the system has its limits. It can penetrate only a little more than half a foot.
āEight inches is all weāve been able to do,ā Charvat said. Visibility āmay be able to be increased by more transit power or lowering the frequency. The lower you go in frequency, the better it is, but it becomes a resolution issue."
But the technology could be a boon for the military, he said. "It can basically tell if there may be a threat inside of a building without having to go inside there. Itās for increasing the situational awareness of the urban war fighter."
But privacy advocates say that is exactly why they are wary of it.
Kade Crockford, privacy rights coordinator for the ACLU of Massachusetts, said she was "extremely concerned" about technology that could make spying easier, especially with the inevitable application of its use against an urban populace.
ACLU of Massachusetts spokesman Chris Ott, in an e-mail, referenced the use of military technology being potentially co-opted for use against civilians as an increasing threat to liberty.
āTechnology is developing at a rate that far surpasses Congressā ability or willingness toĀ adapt our laws to ensure that ordinary people are protected from the vast new powers these toolsĀ provide to the government," Crockford said. "This is an alarming trend, and this case is a perfect example of it. We urgeĀ lawmakers to get ahead of the curve to protect our privacy before it is too late.ā
Charvat, for his part, said he didn't see any other application for the system other than military. āI canāt really think of any civilian use. Maybe it could be used in reconnaissance robots, for navigation for them, but it would be a totally different application.ā

Nearly 400,000 people were deported from the United States in the past fiscal year, the largest number in the history of the U.S. Immigration and Customs Enforcement agency, the government announced Tuesday.
The year-end removal numbers "underscore the administration's focus on removing individuals ... that fall into priority areas" such as lawbreakers, threats to national security and repeat violators, the agency said in a news release.
Overall in fiscal year 2011, immigration officials said, 396,906 individuals were removed. Of these, 216,698, nearly 55%, had been convicted of felonies or misdemeanors. That's an 89 percent increase of criminals from three years ago, the enforcement agency said.FULL STORY
More victims could emerge in a case involving three people suspected of locking four mentally disabled adults in the cramped sub-basement boiler room of a Philadelphia apartment building, the city's police commissioner said Tuesday.
"We don't know the extent of this," Charles Ramsey told CNN. "We do know it goes beyond the borders of Pennsylvania - at least Texas, Florida and Virginia, and we suspect other locations as well."
The case began over the weekend, when the four people were found locked in the room, with no food and only a bucket for a toilet, police said. The pitch-black, 15-foot-by-6-foot space houses what police described as a boiler used to heat the building. A penetrating stench of urine and feces still hung in the chamber days after the discovery.FULL STORY
President Barack Obama continued hammering Republicans over their opposition to his $447 billion jobs plan Tuesday, casting the GOP as handmaids of the rich unwilling to support fair sacrifices in order to help a struggling middle class.
Visiting a school and community center in Jamestown, North Carolina, Obama said "folks in Washington don't seem to be listening" to calls for help.
"I want to work with Republicans," the president insisted. But political leaders need to "focus less on trying to satisfy one wing of one party," he said - an apparent reference to populist tea party conservatives.FULL STORY

āThis is a great day to be Israeli. We will never rest until we save even one life. We believe in life. We do not believe in murder and killing innocent people. That is the difference. May the Palestinians start believing in peace and life. May we have peace one day between Israelis and Palestinians." - jewishcowgirl

Israeli soldier Gilad Shalit, who was captured by Hamas in 2006, is home now after Israel agreed to release 1,000 Palestinian prisoners. The lopsided number has created some controversy, but there is wide support for the deal in Israel.
What did CNN.com readers think of the swap? Most praised Israel for saving a young manās life; they said the move demonstrated how much Israel values all human life. Other readers condemned the Palestinian releases, saying they are all terrorists. Some defended the rights of Palestinians.
bigbadbernie said, āThe point is not the 1:1000 ratio, itās that in a professional military force it is good to know that no one is left behind and you can go into harms way with that knowledge and be more effective. That is the stuff that makes a great nation and separates them from their enemies.ā
IsraeliStude said, āI do want to say that finding out Gilad could watch TV and knew about the support of his parents and the public shows Hamas had at least some compassion. There is hope after all!ā
ModGOP called it āA prime example of how the Israeli government actually cares about their own people!ā
AmitAtlanta said, āThis deal makes no sense. All talk of how much Israel values a life falls on deaf ears knowing fully well Palestinians are ready to give up their lives/their childrenās lives to kill even a Jewish owned mouse! The Israeli action only emboldens the hostile world community to charge that the much maligned Israelis have far more innocent Palestinians rotting in their prisons and emboldens the Palestinians to continue with their kidnappings of Israeli soldiers.ā
sugarnspice said, āThis deal would not happen in any other nation on earth, ONLY IN ISRAEL does the entire nation consider Gilad to be their own son, ONLY IN ISRAEL would people come to refer to Gilad's parents, Noam and Aviva, by their first names, ONLY IN ISRAEL would people remember a lone soldier, not because of his fame, but simply because he was one of theirs.ā
ChefCHEESE said, āItās a great day for Gilad and all the other prisoners who can go back home after years.ā
Guest said, āIt's not easy to set free 1,000 terrorists, but one Israeli boy is worth even 100,000 of them! The important point is that Israel will NEVER leave its soldiers behind. and this is why the people in Israel supports this deal.ā
oferbz said, āThe fact that Israel is swapping one soldier for more than a thousand terrorists, shows the world how much Israel values life itself, unlike the Hamas who sends its people to suicide bomb missions.ā AntiZioNazi1 responded, āCaring after 5 years? Wow !ā
Anatile said, āWelcome home Gilad. We love you. Only the people in Israel understand how much life is precious . You are definitely worth 1,000 people, even more. I'm very proud to be Israeli citizen today.ā
DanJones said, āI wonder how long it will take for Hamas or Hezbollah to kidnap the next āGiliad Shalitā and how many they will kill in the process?ā
lho said, āAnytime you trade 1,000 of anything for 1 of the same thing.....whether you know anything about the items in question, there is absolutely NO doubt that the one thing is worth at least a thousand times more than the 1000 things. Sorry. No way around that.ā
pupplesan said, āThe question remains unanswered within the article. The real answer is twofold: first, Israel knows that many of the people it has imprisoned are innocent and second, obviously, there is an unspoken element of religious elitism involved here.ā
silvery1261 said, āLetās face it. This freed Israeli soldier is not a teenage schoolboy who was kidnapped in his home. He is an Israeli soldier trained to kill, fully armed and in army uniform. He knows the risks and he wasn't in this to distribute flowers to Palestinians or candy to the kids. Why is it so hard for Israeli supporters to admit this fact? Granted that one can take the view that his job was to protect Israeli civilian society, but so were the liberated Palestinians who fight the mightiest army in the Middle East to protect their civilians as well.ā

Police in Montgomery County, Maryland, confirmed Tuesday they have found remains in a wooded area believed to be those of William McQuain, a missing 11-year-old boy.
A search dog team found the body, said Rebecca Innocenti, police spokeswoman. The scene was still being processed Tuesday morning, and she had no information on when a positive identification would be made.
The news comes a week after Curtis Lopez, 45, was arrested in Charlotte, North Carolina. He is accused of killing his wife, 51-year-old Jane McQuain.
The case began when a friend of the boy's mother reported her missing, saying he had not seen her for about two weeks and that he was concerned.
When detectives arrived at the woman's home in Germantown, they found Jane McQuain dead in her bedroom. Her son was not there and the woman's vehicle, a Honda CRV, was gone. It was found later.
Police had been searching for the boy, who they had hope was with a relative or family friend, but said that as time passed, that possibility became āmore and more of a long shot.ā

Susan Sarandon reportedly recently called Pope Benedict XVI a "Nazi" during an interview, and the Anti-Defamation League (ADL) is calling on the actress to apologize.
In a statement posted on the organization's website, the ADL refers to Sarandon's remark as a "disturbing, deeply offensive and uncalled for attack on the good name of Pope Benedict XVI."
As Newsday reported, the actress was speaking about her 1995 movie "Dead Man Walking" with actor Bob Balaban in an interview at the Hamptons Film Festival on Saturday. Sarandon, 65, mentioned that she sent the pope a copy of the anti-death penalty book the film was based on.
"The last one," she said, indicating Pope John Paul, "not this Nazi one we have now."
Balaban tried to gloss over the comment, but Sarandon said it again.
In response on Monday, the ADL's National Director, Abraham Foxman, said in the posted statement, "We hope that Susan Sarandon will have the good sense to apologize to the Catholic community and all those she may have offended...Ms. Sarandon may have her differences with the Catholic Church, but that is no excuse for throwing around Nazi analogies. Such words are hateful, vindictive and only serve to diminish the true history and meaning of the Holocaust."
Israel is freeing more than 1,000 Palestinian prisoners, including hundreds serving life sentences for attacks on Israelis, in exchange for Israeli soldier Gilad Shalit, who was captured by Hamas in 2006.Ā
The move has prompted many to ask if exchanging many people for one man is unusual. In the past, Israel has exchanged prisoners several times with its neighbors. Overall, Israel has released about 7,000 Arab prisoners over the last 30 years in exchange for 19 living Israelis and the bodies of eight prisoners. Here are some of those instances:
In 1985, three Israeli soldiers held in Lebanon were released, but only after Israel freed 1150 Lebanese and Palestinian prisoners.
In June 1998, Israel and the South Lebanese Army released 65 prisoners and the remains of 40 Hezbollah guerrillas for the return of the body of an Israeli soldier killed in combat.
In 2004, an Israeli businessman was released along with the remains of three soldiers. In return, Israel freed 436 Palestinian and Lebanese prisoners.

Today's programming highlights...
10:00 am ET - Geithner on Capitol Hill - Treasury Secretary Timothy Geithner updates Congress on a series of economic issues.
The release of more than 400 Palestinian prisoners in exchange for one detained Israeli soldier elicited waves of celebration Tuesday, both from relatives of Palestinian prisoners and Israelis anticipating the famed soldier's homecoming.
But the situation remains dicey for Israelis opposing the deal.
Hundreds of Palestinian family members turned out in Gaza and the West Bank to welcome their relatives, with some waving flags of the Islamist group Hamas.
Ahmed Qawasmi, 80, is awaiting the release of his son Amer, who was arrested when he was 17 and has been in jail 24 years.
"I am very, very happy for the release of my son Amer," he said, but added: "The celebrations and happiness won't be complete until all Palestinian prisoners are free from Israeli prisons."
Israel agreed to free a total of 1,027 Palestinian prisoners - 477 on Tuesday, and 550 later this year - in exchange for the release of Israeli soldier Gilad Shalit, who was held captive by Hamas for five years.
Chief Palestinian Authority negotiator Saeb Erakat described "an overwhelming feeling of humanity" Tuesday amid the Israeli-Palestinian prisoner swap - and acknowledged that Hamas was able to achieve a deal when the Palestinian Authority could not.
"I have been talking to the Israelis for many, many years about prisoners - the need to release prisoners - and we could not convince," Erakat said.
"It's a good day, and we welcome it (in) the strongest possible terms, and we hope one day we will have nothing but peace on the two sides," he said.
Hassan Mousa, a Hamas leader in the West Bank, echoed Erakat's sentiment.
"This is a great day that (has) brought happiness to all Palestinian people," he said. "It has unified the Palestinian people together. It will free people who have been in Israeli jails more than 34 years and more than 30 years, and many more with high sentences, and will free the women and children alike."FULL STORY
[Updated at 7:25 a.m. ET] The mission to bring home captive Israeli soldier Gilad Shalit has been accomplished, Prime Minister Benjamin Netanyahu announced Tuesday, saying Israel was united in joy at his release and in pain for the price that Israel had to pay for it.
[Updated at 7:17 a.m. ET] Israeli soldier Gilad Shalit was reunited with his family after more than five years in Hamas captivity, Israeli Prime Minister Benjamin Netanyahu's office announced Tuesday.
[Updated at 7:15 a.m. ET] Gilad Shalit walked into Israel a free man after more than five years in Hamas captivity on Tuesday, the Israel Defense Forces said.
Israeli television showed him in the company of IDF soldiers minutes after the announcement, sparking joy in Israel.
He is in good health and is now en route to see his family and top Israeli leaders, the military announced.
Shalit learned about a week ago that he was going to be released, though he "felt it for the last month," he told Egyptian television after his release.
"I missed my family. I missed going out and meeting people," he said in the emotional interview, where he appeared pale, tired, tense, and sometimes out of breath, although he was seated in a chair.
Israel is releasing more than 1,000 prisoners in exchange for Shalit.
"I hope this deal will move the peace process forward," he told Shahira Amin of Egyptian TV, saying he would be glad if the remaining Palestinian prisoners are released "as long as they do not go back to fighting Israel."
The interview came shortly after Egyptian television showed a short clip of Shalit walking unaided with an escort of about half a dozen people. He looked thin and dazed, wearing a dark baseball cap and collared shirt.
Shalit came via Egypt because it acted as a mediator between Israel and Hamas, which do not have relations.
Shalit's father told Israeli television earlier it was the happiest day of his life.
Israel freed 477 Palestinian inmates from Israeli jails shortly before Shalit was released, the first group of a batch of more than 1,000 Palestinians being swapped for Shalit's freedom.FULL STORY
U.S. Secretary of State Hillary Clinton landed in Tripoli on Tuesday, making her the first Cabinet-level American official to visit Libya since the ouster of longtime strongman Moammar Gadhafi.
Clinton landed under tight security in a country where forces loyal to the transitional government are still battling Gadhafi loyalists. She was slated to meet with officials of the National Transitional Council and planned to offer U.S. medical assistance for those wounded in the fighting, according to a senior State Department official traveling with the secretary.
NTC fighters toppled Gadhafi's nearly 42-year-old government in August after six months of fighting. Gadhafi, his son Saif al-Islam Gadhafi and his brother-in-law and intelligence chief Abdullah al-Sanussi are wanted on war crimes charges and remain fugitives.
