A federal investigation into two researchers who wrote a famous report on drowned polar bears is finally over, according to their lawyer.

But the scientists still haven't been allowed to see a copy of the investigation report or its conclusions, says attorney Jeff Ruch of Public Employees for Environmental Responsibility.

Critics have charged that the two-year investigation was a witch hunt into researchers whose work had political implications.

Here's the above-the-fold headline on Sunday's Miami Herald: "Ryan could hurt Romney in Florida."

Good morning.

Our early headlines:

-- It's Deja Vu All Over Again: Campaign's Focus Returns To Iowa.

-- In Egypt, Talk Of Coups And Counter-Coups.

Sunday's sacking (or forced retirements, if you prefer) of Egypt's military chiefs by new President Mohammed Morsi has analysts scrambling to explain what it all means.

Google is eliminating about 20 percent of the jobs at Motorola Mobility, the struggling cellphone manufacturer it finished acquiring earlier this year for $12.5 billion, according to reports from The New York Times, Dow Jones' All Things Digital blog and other news outlets.

Good morning.

With Republican presidential candidate Mitt Romney's vice presidential pick now in the books (if you somehow escaped the news from the weekend, it's Rep. Paul Ryan of Wisconsin), the presidential campaign shifts into a higher gear this week.

This summer, I was one of nearly 200 cyclists who toured D.C. one night in search of the city's most colorful murals in parking lots and back alleys.

The tour was co-sponsored by MuralsDC, a citywide project that trains young artists to paint mural masterpieces over tired, tawdry graffiti.

"It makes art so personal and accessible at once," says Laura Lyons, 20, a summer volunteer.

NPR's business news starts with a spike in gas prices.

Gasoline prices jumped 18 cents over the last couple of weeks. That's the biggest increase so far this year. The Lundberg Survey shows that heading into the weekend, the national average price of a gallon of self-serve was $3.69. Now, analysts say the spike is in part because of some refinery and pipeline issues around the country.

Over the weekend, GOP presidential hopeful Mitt Romney named Wisconsin Rep. Paul Ryan as his running mate. David Greene talks to Ryan Lizza, a reporter for The New Yorker, who recently profiled Ryan for the magazine.

Egypt's first freely elected president made history there Sunday by confronting the military power structure. Mohammed Morsi forced top military leaders into retirement and shifted the balance of power to the civilian government. Analysts called it the boldest and most unexpected move of Morsi's fledgling presidency. NPR's Leila Fadel has the story from Cairo.

For more on this big weekend in politics, we turn to Cokie Roberts for some analysis. Good morning.

COKIE ROBERTS, BYLINE: Hi, Renee.

MONTAGNE: So we just heard in Ari's piece the excitement Paul Ryan is generating among the Republican faithful. Is that partly why Mitt Romney chose him as his running mate, to generate some of the kind of enthusiasm that has been missing from his own campaign?

Researchers used economic principles to predict which countries would win the most medals at the London Olympic Games. The study was 95 percent accurate for the 2008 games. And this time around, it was 97.7 percent accurate.

The addition of Rep. Paul Ryan to the GOP ticket is certain to elevate health care as a campaign issue this fall.

One factor that has kept Poland somewhat insulated from the eurozone crisis is domestic consumer spending. Poland had more than 4 percent growth last year while the rest of the continent was mired in negative or flat growth. Poles have more discretionary income than ever before, and they're using it to buy things in swank malls cropping up all over the country.

When it comes to a healthy diet — especially for women, and especially after menopause — nutritionists, doctors, everybody it seems, will tell you: calcium, calcium, calcium.

Federal health officials recommend that women and men younger than 50 consume 1,000 milligrams of calcium per day. The recommendation goes up to 1,200 milligrams after age 70 for men and after menopause for women, when a major drop in estrogen causes bone loss.

Many of us experience heartburn, or reflux, from time to time — and when we do, we're quick to point the finger at heavy, fatty meals. But that burning, uncomfortable feeling may also be the result of what we're drinking: namely, coffee and other caffeinated beverages, and alcohol.

"Alcohol has a direct effect" on heartburn, says Kevin Ghassemi, a gastroenterologist at the University of California, Los Angeles. "Temporarily, of course."

In 1990, 78 percent of Americans supported tougher restrictions on gun sales, according to a Gallup poll. A decade later, that number fell to 44 percent.

Part of the reason has to do with how the debate has been framed: one between those who want to ban all guns and those who want to protect the right to own them.

President Obama has long used House Republicans as a foil. Now that one of the leaders in that group, Paul Ryan, is on the ticket alongside Mitt Romney, the connection is that much clearer. NPR's Scott Horsley joins host Guy Raz to talk about the president's response to the newly formed GOP ticket.

The U.S. men's basketball team defended its Olympic title today as the London Summer Games draw to a close, and there was plenty of drama elsewhere on the final game of the competition. NPR's Tom Goldman tells host about Guy Raz the greatest moments and those that were a little embarrassing.

It's a moment of pride and glory when athletes hear their country's national anthem ringing out at the medal ceremonies of the Olympic Games. Host Guy Raz talks to freelance journalist Alex Marshall, whose writing a book on the history of national anthems, about some of the patriotic tunes.

How do a Swedish producer and a Malawian singer end up collaborating? The partnership that became The Very Best was sparked several years ago, when Johan Karlberg stopped into a London secondhand store that was run by the Malawi-born Esau Mwamwaya, and the two started talking music.

Olympic winners like gold medalist Claressa Shields have said the games were a learning experience, but what were they learning? Hard work? Sure. Sportsmanship? Maybe. The metric system? Certainly not.

U.S. judo competitor Kyle Vashkulat competes at 100 kg, which he knows means he weighs 220 lbs. But does he know height?

"We were in a sauna, and the guy's telling us the height of the boxers, and he's like, 'Yeah, this guy's like, 1.7 meters' — and we're like, 'How tall is that?'" Vashkulat says, laughing.
