Newt Gingrich, a self-described space nut, has long been a supporter of the U.S. space program. Now the Republican presidential hopeful is proposing what he calls a bold program that would send Americans back to the moon and beyond.

During a campaign event on Florida's Space Coast — hard-hit by the recession and the space program's uncertain future — Gingrich talked about coming of age at the time of Sputnik, the first satellite, launched in 1957 by the Soviet Union. He recalled reading science-fiction author Isaac Asimov and Missiles and Rockets magazine.

Quiznos narrowly avoided bankruptcy this week when the sandwich chain shifted ownership to private equity firm Avenue Capital in exchange for erasing some debt.

The recession and poor management have hit the Denver-based sub-maker hard. The company once boasted more than 5,000 restaurants, but 40 percent of them have now shut their doors.

Andre Bonyadian owns nine Quiznos franchises in and around Los Angeles.

Just four years ago, Starbucks seemed to be losing its mojo. Howard Schultz, the man who made Starbucks a household name, returned to the company as CEO. He closed hundreds of stores, streamlined operations and set the company on a path to record revenues and strong profits.

Starbucks serves 60 million beverages a week, which adds up to big profits. The company reports its earnings Thursday. In a bid to further expand its consumer base, Starbucks has a new roast and plans to produce more retail products to sell outside of its coffeehouses.

Greece is broke. But there's no blueprint for a country to declare bankruptcy, so Greece's creditors are sort of making things up as they go along.

"You're taking some sort of loss," Hans Humes of Greylock Capital Management told me. "But it's like, how much of a loss do you take? There's this thing called sovereign immunity. You can't go in and take the Acropolis."

Alice Waters has moved from the kitchen to the garden to the soap box in her 40 years as a pioneer of the sustainable and locally grown food movement. But on one recent night, The Salt found her "hanging" in the National Portrait Gallery in Washington.

Robert Siegel interviewed Rep. Ron Paul on All Things Considered on Jan. 25. This is an edited transcript of their conversation.

ROBERT SIEGEL: Representative Paul, welcome to the program once again.

REPRESENTATIVE RON PAUL (R-TX): Thank you. Good to be with you.

Heart disease remains the leading cause of death in the U.S. But who's at the most risk?

A study in the lastest New England Journal of Medicine offers a simple way to predict the risk of a fatal or debilitating heart attack or stroke for a middle-aged person over the rest of his or her life.

Men are more apt than women to lose thinking ability as they age, according to new research. And that mild cognitive impairment often leads to dementia.

But people can reduce their risk of mild cognitive impairment by staying healthy and educated, according to Rosebud Roberts, a professor of epidemiology at the Mayo Clinic who led the study. "There is a lot that people can do," she told Shots.

A day after delivering his State of the Union address to Congress, President Obama took his message on the road. Obama hoped that stops at manufacturing sites in Iowa and Arizona would drive home his point that the government should do more to encourage factory jobs.

The three-day trip also includes stops in Colorado, Nevada and Michigan. Those are all states likely to be important in the November election.

Obama kicked off his road trip at Conveyor Engineering and Manufacturing, a factory in Cedar Rapids, Iowa.

Treasury Secretary Timothy Geithner told Bloomberg Television today that he's "pretty confident" he won't be asked to stay in his job if President Obama is re-elected for a second term.

"He's not going to ask me to stay on, I'm pretty confident," Geithner said. "I'm confident he'll be president. But I'm also confident he's going to have the privilege of having another secretary of the treasury."

Dudley Butler is quitting his job tomorrow. Never heard of him? He's President Obama's appointee to run the division of the U.S. Department of Agriculture that governs antitrust issues in the meat industry. He was part of a cadre of high-level bureaucrats charged to expose and fight agribusiness monopolies. In fact, he was the last of that group.

"After more than 30 years of handing prayer cards to customers aboard its planes, Alaska Airlines has decided the practice is outdated and will stop doing it on Feb. 1," The Seattle Times reports.

A few things struck us about this news.

Samantha Garvey, the homeless teen who came into the national spotlight after she became a semifinalist in the prestigious Intel Science Talent Search competition, has had a bittersweet 24 hours.

Cairo's Tahrir Square overflowed with Egyptians today. Traffic was snarled for miles as people jammed bridges and streets. The crowd marked the first anniversary of the popular uprising that drove Hosni Mubarak from power.

And as NPR's Soraya Sarhaddi Nelson reports from Cairo, many people did not come to celebrate.

Arizona Rep. Gabby Giffords took to the House floor Wednesday one last time to say good-bye, for now, to her colleagues. It was an emotional scene as she handed in her resignation, a little more than a year after being gravely injured in an assassination attempt.
