Start the "computers are conquering the world" jokes now. "Jeopardy!" master Ken Jennings already has.
The IBM supercomputer Watson won its second "Jeopardy!" game in Wednesday's edition of the TV show, completing a sweep of its two human opponents, including Jennings, who acknowledged mankind's trivia inferiority before the match was even over.
"I for one welcome our new computer overlords," Jennings wrote under his correct Final Jeopardy! solution, prompting laughter from the studio audience.
Watson - despite being far from perfect - was too far ahead in the two-game match to be caught. It beat Jennings and fellow "Jeopardy!" champion Brad Rutter, earning $41,413 for the day and $77,147 for the two-game total.FULL STORY
Editor's note: Nancy Grace's new show on HLN, "Nancy Grace: America's Missing," is dedicated to finding 50 people in 50 days. As part of the effort, which relies heavily on audience participation, CNN.com's news blog This Just In will feature the stories of the missing.
This is the 23rd case, and it will be shown at 9 p.m. ET Wednesday on HLN.
More than 30 years after Etan Patz's face became the first of a missing child to appear on a milk carton, authorities still aren't sure what happened to him.
Etan was 6 when his parents finally gave him permission to walk to a school bus stop alone in New York City on May 25, 1979. The stop was just two blocks from his parentsâ€™ apartment.
A Pennsylvania English teacher who called her high schoolÂ students "rude, lazy, disengaged whiners" on her personal blog is standing by her comments after being suspended from her position over the controversy.
"I'm sorry it was taken out of context but I stand by what I said," Natalie Munroe told ABC's "Good Morning America" Wednesday.
The 30-year-old expecting mother said she wrote the posts on natalieshandbasket under the name Natalie M. with the intention that only friends would read the blog. The posts are no longer available on the blog but searchable in a cached version of the site.
"I was writing it not about anyone specific. They were caricatures of students that I've had over the years, things that I would say if we weren't limited in the canned comments that we're allowed to write. And again, it was partially meant tongue in cheek for me and my friends."
In several posts between August 2009 and November 2010, Munroe vented her frustrations - and shared a few positive experiences - with students she found to be "out of control" and lacking "honor and good moral character."
She has been suspended with pay, and her lawyer said she is waiting to see how the school will proceed before deciding whether to take legal action.

Albert Pujols will be a St. Louis Cardinal in 2011. After that is anybodyâ€™s guess.
Yet another deadline passed Wednesday when Pujols and the Cardinals failed to reach a contract extension before their mutually agreed-upon noon Eastern deadline. The two sides had extended negotiations, hoping to reach a last-minute deal, but failed to settle on terms.
Now, contract talks between the three-time MVP and the Cards will be broken off until the fall as the slugger has repeatedly said he does not want his deal to be a distraction during the season.
Discussions between St. Louis and Pujolsâ€™ agent, Dan Lozano, had been heating up in recent weeks. SI.comâ€™s Jon Heyman reported Tuesday that the Cards offered Pujols an eight-year deal in excess of $200 million.
According to Heymanâ€™s sources, Pujols, 31, is seeking a greater deal than Alex Rodriguezâ€™s record 10-year, $275 million contract signed in 2008. Itâ€™s not clear whether the length of the deal or the money is holding up the Pujols deal.
Pujols has a no-trade clause and is unlikely to go anywhere during the upcoming season but could presumptively go anywhere once it's over. The consensus best player in baseball will be a free agent and probably will have every team in baseball expressing some degree of interest in landing his talents.
Despite not reaching a deal, the nine-time All-Star will still report to Jupiter, Florida, on Thursday and join his teammates for the first day of spring training. The Cardinals are hoping to be a contender with Pujols in 2011, but without a deal, a cloud of uncertainty could disrupt their season.

[Update 1:35 p.m. ET] One of the three deputy U.S. marshals shot Wednesday has died, according to U.S. Marshals Service spokesman Jeffrey Carter.
The officer died from a shotgun blast while serving an arrest warrant in Elkins, West Virginia, Carter said.
One deputy "continues to recover from his injuries," and the third has been treated and released, the spokesman said.
[Posted 11:04 a.m. ET] Three deputy U.S. marshals were shot while serving an arrest warrant at a home in Elkins, West Virginia, at about 8:30 a.m. Wednesday, a spokesman for the U.S. Marshals Service said.

Thousands of people had gathered Wednesday for a peaceful funeral procession for a Bahraini man killed when clashes erupted during another protester's funeral procession, the president of a human rights group said. Bahrain's Interior Ministry said those involved in the deaths of two people during recent protests are in custody.
New York Times columnist Nicholas Kristof told "American Morning" that the protesters' demands are changing.
Initially, protesters in Bahrain talked about wanting more democracy and to have political prisoners released, Kristof told T.J. Homes. Increasingly, protesters are calling for the overthrow of the ruling family and the conversion of Bahrain into a constitutional monarchy in which the king would reign, but not rule, Kristof said.
â€śThey were really outraged at the government's brutality toward the peaceful protests earlier in the week. And at those two deaths,â€ť he says.
There is some uncertainty about where protests will go later today, Kristof said.
â€śNow that the regime has backed off, it's a little hard to say where things will go,â€ť he said. "It is possible that similar concessions will win the day. And that there will be some kind of a truce and agreement to have more democracy, some more concessions. And then people will go home. It's just very hard to predict.â€ť
Thanks to "crowd funding," it looks as if Detroit will get its RoboCop statue after all.
A week after Mayor Dave Bing took to Twitter to dismiss the idea, an independent online campaign has raised more than $50,000 to build a monument to the 1987 sci-fi movie hero, the Detroit Free Press reports.

It's something, but it's not the real thing, Coca-Cola says.
"Rest assured that while many third parties have tried over time to crack the secret formula of Coca-Cola ... there truly is only one 'real thing,' " Ted Ryan, Coca-Cola's manager of archives and exhibits, wrote Wednesday on a company blog.
The company insists the formula is locked in a bank vault in Atlanta, Georgia, and only a handful of employees know it or have access to it.
The 19th-century handwritten list of ingredients that "This American Life" host Ira Glass found pictured in a 1979 column in the Atlanta Journal-Constitution may have been an attempt at a knockoff, Coca-Cola's official archivist, Phil Mooney, told CNN.
Interest in the secret recipe is so high that heavy traffic reportedly brought down the radio show's Web server after the segment aired.
While the formula Glass found might have some relation to the original product of the 1800s, it clearly is not today's recipe: The list of ingredients includes coca and alcohol, a Tuesday story in the Journal-Constitution notes.
All the secrecy is nothing more than marketing anyway, experts insist.
"Today, anybody with access to a sophisticated chemistry laboratory could analyze the formula of Coke, but no one can call a product called Coke other than the Coca-Cola Company," John Sicher, editor and publisher of "Beverage Digest," told the paper. "The so-called 'secret formula' is a wonderful story of lore and mystery, but in reality, the value today is the brand, not the formula."
Middle East protests - Demonstrations against governments in the Middle East continue to rage, inspired by the weeks-long, anti-government protests in Egypt that forced President Hosni Mubarak to step down. In Bahrain, anti-government protesters rallied peacefully at the funeral of a man killed while protesting on Monday. Protests were far more violent in Iraq where demonstrators gathered outside the governor's office in Kut, about 60 miles south of Baghdad. One person was shot and killed when private security guards and Iraqi security forces opened fire. Twenty-eight people were wounded.
Wednesday marks the sixth day of anti-government protests in Yemen. Sanaa University students took to the street initially demanding improved curriculum, but their rally became an anti-government protest. Pro-government demonstrators showed up and began throwing rocks, two witnesses told CNN. There were no reports of injuries at the rally.

Florida teens in court -Â Three Florida teenagers accused of setting another boy on fire in late 2009 are scheduled to be in court Wednesday. It could be the first time the suspects' side of the story is heard. The three teens - Denver Jarvis and Mathew Bent,Â both now 16, and Jesus Mendez, now 17 - have been charged as adults with second-degree attempted murder. The teens are accused of pouring alcohol on the victim, who is now 16, and setting him on fire after a dispute about buying a video game.
A federal court on Wednesday sentenced a Somali man to nearly 34 years
in prison for acts related to high-seas piracy.
Prosecutors say Abduwali Muse acted as the ringleader when he and three other men seized the U.S-flagged Maersk Alabama by force about 350 miles off the coast of Somalia on April 8, 2009.
Once on board, the armed men demanded the ship be stopped, then took a lifeboat and held the captain of the ship, Richard Phillips, hostage on it.
Muse, who entered a guilty plea last May, apologized in the New York courtroom on Wednesday.
"I'm sorry very much for what happened to victims on ship. I am very sorry about what I caused," he said. "I was recruited by people more powerful than me. I got my hands into something more powerful than me and I am sorry.
"I ask forgiveness for all the people I harmed and the U.S. government."

Students can obtain condoms at nine of Boston's 36 public high schools, the Globe reported.
