In California, state officials are planning a multibillion-dollar environmental restoration of the inland delta near San Francisco Bay. There's only one problem: No one knows what the landscape used to look like. Ninety-seven percent of the original wetlands are gone, so the state is turning to historians for help.
This detective story begins on a sunny day in a dry field of corn, about an hour east of San Francisco.
How does a president bring the war in Afghanistan to an end? There are 68,000 American troops serving in the country as the war enters its 12th year.
The war hasn't been a major issue in the presidential campaign, and polls show American voters are tiring of the war. But the next commander in chief will find the Afghan war among the most difficult of many foreign policy challenges.
Both President Obama and Gov. Mitt Romney appear to agree on a date: the last day of December 2014. That's when the Afghan security forces are scheduled to takeover.
Despite its liberal reputation, the home of Jack Kennedy and Tip O'Neill has never elected a woman as governor or senator. And in Massachusetts Sen. Scott Brown's tight re-election race with Democratic challenger Elizabeth Warren, gender could prove the difference.
When Brown won his Senate seat in a special election in 2010, he came away unscathed by something his female opponent at the time would have had a much harder time explaining away. He posed nude for Cosmopolitan when he was 22 to help pay for law school.

What's it like to be a third-party candidate running for president? Ralph Nader can tell us.
"You're excluded from the debates," he says. "You spend an exhausting amount of time, until Labor Day, trying to get over the ballot access barriers. Your petitioners are harassed in the streets; you're subjected to baseless lawsuits by one party or another."
Nader has run for president three times – four if you count the time he ran unofficially. In 2000, he managed to win almost 3 percent of the national vote.
Major defense companies said this week they will not send out layoff notices to warn of big job cuts in January, taking away the prospect of embarrassing layoff notices right before the November elections.
That's led to charges that the White House overstepped when it told the industry the notices are not needed.
Nov. 6 is 32 days away, but for millions of Americans, there is no longer an Election Day.
Thirty-two states and the District of Columbia now have early voting, which is under way even now in eight states. Hundreds of thousands of votes have already been cast, most before this week's presidential debates or Friday's jobs report, and all ahead of the three future debates and any unforeseen October event that might test the mettle of a candidate.
On Sunday, Venezuelan President Hugo Chavez faces his most serious election test in 14 years of power. Though he has easily beaten his adversaries in the past, Chavez now confronts a 40-year-old former governor who has been electrifying the crowds.
The stakes are high. If Chavez loses, it could mean the end of his socialist experiment in the oil-rich nation.
In speech after speech, Chavez is like the Chavez of old — bombastic, loud, defiant, with grand dreams about projecting Venezuelan influence worldwide.
The U.S. has been carrying out drone strikes in Pakistan for some eight years, but it's done so under a policy that has emerged piecemeal over that time.
"It started in 2004, when drones were really an oddity," says Daniel Markey, a senior fellow at the Council on Foreign Relations. He was on the State Department's policy planning staff when it all started during the Bush administration.
