This is WEEKEND EDITION from NPR News. I'm Scott Simon, and the polls are open in South Carolina; first southern state to hold a primary in the race for the Republican presidential nomination of 2012, the stakes are critical. The state has picked the eventual nominee in every year since 1980, and it's sure been a turbulent week with Rick Perry dropping out, Iowa declaring Rick Santorum the winner of its caucuses and Newt Gingrich closing in on Mitt Romney.
One hundred years ago this week, British explorer Robert Falcon Scott reached the South Pole with a small crew of men. They all perished on the return trip. In 2008 on Weekend Edition, NPR's Daniel Zwerdling reported from the South Pole on Scott's tragic journey. To mark the 100th anniversary, we reprise that story.
SIMON: Last week, we spoke with Clay Johnson, an open-source advocate and digital strategist, about his new book, "The Information Diet: A Case for Conscious Consumption."

In the late 19th century, scores of celebrated, valorous explorers attempted to reach the North Pole. Groups of explorers from the U.S., Europe and Scandinavia invented clever new equipment, raised money, stirred national pride and enthralled the world by attempting to march, sail or sled to the most cold, remote and unseen place on Earth.
But it was a perilous business: Of the 1,000 people who tried to reach the North Pole in the late 1800s, 751 died during their attempt, author Alec Wilkinson tells NPR's Scott Simon.
