While others analyze what Thursday's GOP presidential debate does or doesn't tell us about what may or may not happen Saturday when South Carolina Republicans hold their primary, here's the top news from that four-man clash in Charleston:

The timekeepers at the International Telecommunication Union's Radiocommunication Assembly, who were supposed to decide this week whether to keep or eliminate the leap second, have decided to take some more time to decide.

Three years, apparently, the BBC reports.

The experts, it says, "were unable to reach a consensus, so moved the matter to a meeting in 2015."

A rare four-volume set — John James Audubon's Birds of America — stands a good chance of becoming the most expensive such books ever auctioned on Friday.

For decades, until 2010, someone appeared at Edgar Allan Poe's grave site in Baltimore before dawn on Jan. 19 — his birthday.

The mysterious visitor, who was never identified, would leave behind three roses and a half-filled bottle of cognac as a tribute to the man who wrote The Raven, The Fall of the House of Usher and other classic poems and tales.

The ship, with about 4,200 passengers and crew aboard, ran into rocks on Friday and listed over to its starboard side. Eleven people are confirmed dead.

"Running short of cash and unable to sell 1,100 digital imaging patents that could have rescued it," as Rochester's Democrat and Chronicle writes, Eastman Kodak Co. today took the long-expected but still painful step of filing for Chapter 11 bankruptcy protection.
