Rep. Thaddeus McCotter, R-Mich., is facing the daunting prospect of running a write-in campaign to get re-elected this year, as his campaign fell far short of the number of petition signatures he needs to qualify for the August primary ballot.

Compounding McCotter's troubles: It appears election fraud may have played a part in the failure.

When it comes to architecture, sustainability and affordability can mean many things: Salvaged wood becomes new flooring, old newspapers are shredded into insulation.

But a few architects are taking green building one step further: creating entire homes and businesses out of discarded shipping containers — an approach some have dubbed "cargotecture."

Approximately a quarter-million shipping containers pass through Oregon's Port of Portland each year. These are big boxes — 40 feet long and weighing thousands of pounds.

What snarky headline writer could resist a story about "hot tuna?" Or how about "tuna meltdown?"

Really, it seems just plain daffy to ignore a new study that says some Pacific bluefin tuna picked up traces of radioactive material from the Fukushima nuclear disaster last year and brought it across the Pacific Ocean.

A shortage of Adderall began last year, sending millions of people with attention deficit/hyperactivity disorder and narcolepsy on perpetual wild goose chases to find drugstores with the pills they need to stay alert and focused.

So it's not surprising that Adderall counterfeiters have seized a big marketing opportunity. What is surprising is their clumsiness.

The most potentially influential politician you've probably never heard of, former two-term Maine Gov. Angus King, on Tuesday officially entered the race to replace retiring moderate GOP Sen. Olympia Snowe.

King, 68, an alternative-energy entrepreneur and supporter of President Obama, filed more than 6,000 signatures with Maine's secretary of state to ensure his place on November's ballot.

He'll run as an independent, as he did for his successful gubernatorial runs in the 1990s.

On a recent Monday morning in Washington, D.C., a group of 3-year-old preschoolers bumbled their way into a circle, more or less, on the rug of their classroom. It was time to read.

The children sat cross-legged as their teacher, Mary-Lynn Goldstein, held high a book, Don't Let the Pigeon Drive the Bus. There was a short conversation about pigeons, then, for reasons that weren't entirely clear, cows; and then Goldstein began to read. She read as most teachers read, occasionally stopping to ask a question, point out a picture or make a comment about the story.

Congress is considering legislation allowing the government to search through Internet traffic for early warnings of cyberattacks. The bills are controversial — worries about government surveillance have led to protests online.

The government does have a tool that could calm fears about this kind of legislation — it just doesn't use it.

America is the land of opportunity — that's the bedrock of the American dream. Many expect each generation to do better than the last.

That dream of economic mobility is alive and well for Pam Krank and her husband, Brian McGee. The two are proud owners of The Credit Department Inc., a successful business in the Minneapolis suburb of Mendota Heights.

"Mostly manufacturing companies around the world will hire us to study their customers and tell them how much ... unsecured credit they should grant to each customer," Krank explains.

At the moment the polls close in Texas Tuesday evening, most media outlets and very likely even the Mitt Romney campaign will declare that he has secured enough delegates to win the Republican nomination for president.

For what it's worth, there are two problems with that statement. First, as a practical matter, Romney actually won the Republican nomination when the other candidates competing for delegates in the primaries and caucuses stopped doing so. That was weeks ago.

Back in early April, a Philippine navy frigate tried to arrest Chinese fishermen accused of poaching sharks and giant clams.

But more is at stake than a boatload of seafood.

Neighboring countries say confrontations like this are growing as China asserts claims to territory well beyond its coastline. And analysts think China is testing America's resolve in the region.

Philippine officials say China still has more than 30 boats in the contested area, which is widely known as Scarborough Shoal, though the Chinese call it Huangyan Island.

Saying that each one of the recipients has touched countless lives, President Obama presented 13 Presidential Medals of Freedom during a ceremony in the East Room of the White House today.

All of the people on the stage, Obama said, "are my heroes individually." He said that if it were not for John Doar, the Justice Department official who personally escorted University of Mississippi's first black student to campus, he would not be president.

One of the day's most-discussed stories has to be The New York Times' report headlined "Secret 'Kill List' Proves A Test Of Obama's Principles And Will."

It's a long, detailed look at how the president has "placed himself at the helm of a top secret 'nominations' process to designate terrorists for kill or capture, of which the capture part has become largely theoretical."

Ashley Dias, 26, is waiting for lungs. She has cystic fibrosis and needs a lung transplant to survive. She's got a tracheostomy tube in her neck so she can only mouth out words.

Yesterday, a short piece in a Japan-based foreign affairs magazine caused a lot of surprise: U.S. Special Forces have parachuted into North Korea "to spy on Pyongyang's extensive network of underground military facilities," The Diplomat reported.

The New York Times' Frank Bruni floated the idea, saying he'd heard "a vague murmuring" about Michelle Obama running for the Senate from Illinois in 2016.

It's the sort of question you toss out to a table full of politics buffs — sharing a pitcher of cold beer. (We'll provide the aficionados; you imagine the table and the cold pitcher.)

Which presidential election in American history most resembles the coming election between President Obama and Mitt Romney — and why?

If a goat walks about 2,000 miles from Arizona to Chicago can that "reverse the curse" that has plagued the Cubs for nearly 67 years?

Odd as that question sounds, it's about to be put to the test.

Five Cubs fans and a goat have just finished a three-month walk from Mesa, Ariz., to the Windy City and are due at Wrigley Field this afternoon when the Cubs host the San Diego Padres.

The International Monetary Fund's boss, Christine Lagarde, made a lot of Greeks very angry with an interview she gave The Guardian on Friday.

Essentially, Lagarde said she has very little sympathy for the Greeks and that if they want to solve their financial problems they should just pay their taxes.

Here's what she told the paper exactly:

Word from the antivirus experts at Kaspersky Lab that "we've found what might be the most sophisticated cyber weapon yet unleashed," and that this Flame spyware is targeting Iran and some places in the Middle East, is getting lots of attention this morning:

-- "Massive Cyber-Attack Discovered, Researchers Say." (BBC News)

Can someone actually be hooked on a behavior, like gambling?

Problem gambling isn't considered a true addiction in medical circles. But that may change as psychiatrists revise the diagnostic manual that spells out criteria for more than a dozen varieties of mental disorders.

If you listen to the Morning Edition interview with first lady Michelle Obama, you'll know she's come out with a new book about the White House garden.
