input: Make use of the article to answer the questions. Hong Kong (CNN) -- The world watched, as the London 2012 Olympic Games opened with director Danny Boyle's elaborate ode to England, and furiously tapped their reaction on social media.

But one comment on Twitter has sparked a political fracas on the home soil of the games, as a British member of Parliament lamented the "multi-cultural crap" of the 27 million ($42.4 million) ceremony.

Entitled "Isle of Wonder," Boyle -- the Oscar-winning director best known for hit movies "Trainspotting" and "Slumdog Millionaire" -- put together a star-studded on-field dramatization that drew on Shakespeare and Brit Pop to chart Britain from its pastoral roots through the Industrial Revolution to James Bond, Harry Potter and the Beatles.

"The most leftie opening ceremony I have ever seen -- more than Beijing, the capital of a communist state! Welfare tribute next?" wrote Aidan Burley, a Conservative Party MP who was fired as a ministerial aide in David Cameron's government after revelations he attended a Nazi-themed stag party in France last year.

"Thank God the athletes have arrived! Now we can move on from leftie multi-cultural crap. Bring back red arrows, Shakespeare and the Stones!" he added minutes later.

Burley backpedaled after the strong online backlash against his comments, posting: "Seems my tweet has been misunderstood. I was talking about the way it was handled in the show, not multiculturalism itself."

input: (CNN) -- An Arizona couple who wanted to adopt a woman's baby know more than they're saying about the 8-month-old boy's disappearance, police say.

Gabriel Johnson hasn't been seen since December 26, police said, and his mother was arrested last week in Miami Beach, Florida, after not reporting for a December 28 child custody hearing in Arizona.

"We have some good indications at this point with our investigation that Tammi and Jack Smith do know more information than they have provided to us that could possibly lead us to Gabriel," Sgt. Steve Carbajal, spokesman for the Tempe (Arizona) Police Department, told HLN's Nancy Grace on Thursday.

For their part, the Smiths told HLN's Jean Casarez on "Nancy Grace" that they voluntarily took polygraph tests Friday at the Tempe Police Department.

"The polygraph test is not like what you see on TV," Jack Smith said. "It's almost like being strapped into the electric chair, so it's very intensive. And we were very happy to do it."

The Smiths have said they met Elizabeth Johnson, 23, seven months ago during a long layover at an airport, and later the three discussed a plan to adopt Johnson's child, Gabriel.

But the boy's father, Logan McQueary, has legal custody and has said Elizabeth Johnson urged him to sign papers giving the Smiths custody of the boy, but he refused.

"She didn't want Logan to have the baby, and we couldn't adopt the baby because Logan wouldn't sign the papers," Tammi Smith said on "Nancy Grace." 1. What did the AZ couple want to do?

Q: Unlike chemists and physicists, who usually do their experiments using machines, biologists and medical researchers have to use living things like rats. But there are three Nobel prize-winning scientists who actually chose to experiment on themselves - all in the name of science, reported The Telegraph. 1. Werner Forssmann (Nobel prize winner in 1956) Forssmann was a German scientist. He studied how to put a pipe inside the heart to measure the pressure inside and decide whether a patient needs surgery. Experiments had been done on horses before, so he wanted to try with human patients. But it was not permitted because the experiment was considered too dangerous. Not giving up, Forssmann decided to experiment on himself. He anaesthetized his own arm and made a cut, putting the pipe 30 centimeters into his vein. He then climbed two floors to the X-ray room before pushing the pipe all the way into his heart. 2. Barry Marshall (Nobel prize winner in 2005) Most doctors in the mid-20th century believed that _ was down to stress, spicy food or an unusually large amount of stomach acid. But in 1979 an Australian scientist named Robin Warren found that the disease might be related to a bacteria called Helicobacter pylori. So he teamed up with his colleague, Barry Marshall, to continue the study. When their request to experiment on patients was denied, Marshall bravely drank some of the bacteria. Five days later, he lost his appetite and soon was vomiting each morning - he indeed had gastritis. 3. Ralph Steinman (Nobel prize winner in 2011) This Canadian scientist discovered a new type of immune system cell called the dendritic cell. He believed that it had the ability to fight against cancer. Steinman knew he couldn't yet use his method to treat patients. So in 2007, when doctors told him that he had cancer and that it was unlikely for him to live longer than a year, he saw an opportunity. With the help of his colleagues, he gave himself three different vaccines based on his research and a total of eight experimental therapies. Even though Steinman eventually died from his cancer, he lived four and a half years, much longer than doctors had said he would.
