Here is a look at some of the stories that CNN plans to follow this week:
Presidential contests kick off with Iowa caucuses
The GOP’s first step in nominating a challenger to President Barack Obama takes place Tuesday.
Iowa’s caucuses will kick off the 2012 presidential primary and caucus calendar. Candidates will be looking to meet or beat expectations to gain momentum for the next contest, which is New Hampshire’s primary on January 10.
Late last week, an NBC News/Marist poll indicated that 23% of likely Iowa GOP caucus-goers supported former Massachusetts Gov. Mitt Romney, with 21% backing Rep. Ron Paul of Texas. The survey is similar to a CNN/Time/ORC International poll, released Wednesday, that also indicated Romney and Paul were basically tied for the top spot, with former U.S. Sen. Rick Santorum surging and former House Speaker Newt Gingrich fading, among likely Iowa GOP caucus-goers.
On Saturday, four days after the caucuses, GOP candidates will take part in an ABC News debate in Manchester, New Hampshire.
New year, new laws
With the start of a new year this week, many new laws - including some that cover some of the nation's most contentious issues - will take effect across the United States.
Among those taking effect Sunday, CNN's Josh Levs reports, is a controversial California provision requiring that schools add "lesbian, gay, bisexual and transgender Americans" to the list of those whose contributions "to the development of California and the United States" must be taught in schools.
In New Hampshire, starting Sunday, minors will have to inform a parent before getting an abortion or seek a court order to avoid parental notification.
Van der Sloot's trial begins
The trial of a Dutch man charged with killing a 21-year-old woman in Peru last year is expected to begin Friday in Lima.
Joran van der Sloot is accused of killing Stephany Flores in his Lima hotel room last year. Police say he took money and bank cards from her wallet and fled to Chile, where he was arrested a few days later.
He was charged in September with "qualified murder" and simple robbery, which carry sentences of 28 years and two years, respectively.
Van der Sloot also was once the prime suspect in the case of Alabama teen Natalee Holloway, who vanished while on a graduation trip to the Caribbean island of Aruba in 2005. He was arrested twice but never charged in connection with Holloway's disappearance, which is still unsolved.
He also faces extradition to the United States. In June 2010, a federal grand jury in Alabama indicted van der Sloot on charges of wire fraud and extortion after allegations surfaced that he tried to extort $250,000 from Holloway's mother. He was given a total of $25,000, and authorities believe he used that money to travel to Peru and participate in a poker tournament, where he met Flores.
Mubarak's trial resumes
A trial of former Egyptian President Hosni Mubarak is scheduled to resume in earnest Monday in Cairo following a months-long break.
One session was held on Wednesday - the first since the trial was put on hold. During the break, families of slain protesters tried to have the judge disqualified, though that attempt was unsuccessful.
Mubarak, 83, is charged with ordering the killing of protesters to try to quash the uprising that ended his 30-year rule in February. He also faces corruption charges and has pleaded not guilty. Former Egyptian Interior Minister Habib El Adly, six of his aides and two of Mubarak's sons are also on trial on a variety of charges.
Mubarak's trial proceedings are expected to be held daily starting Monday, a lawyer connected with the case has said.

Middle East peace talks
Israeli and Palestinian representatives will meet in Amman, Jordan, on Tuesday. It's an effort to relaunch negotiations between the two sides after more than a year of deadlock.
"Jordan's efforts are based on the belief that the two-state solution, which leads to the establishment of an independent and sovereign Palestinian national state, is a top Jordanian interest," a spokesman for the Jordanian Foreign Ministry said, according to the country's state-run Petra news agency.
Peace talks between the two sides fell apart over a year ago over disagreements on the issue of Israeli settlements in the West Bank.
