For years scientists have been faced with a mystery about the planet Mercury. Its iron core is much bigger than that of most other planets. More than half of Mercury's mass comes from its core. In comparison, about 32 percent of Earth's mass comes from its core.
Scientists theorized that was because Mercury is so close to the sun that its rocky surface simply melted away.
A new study, which was released along with a series of other papers about Mercury in this week's issue of Science, disputes those theories.
"When Hank Williams died, he left behind a scuffed, embroidered brown leather briefcase. Like its owner, the briefcase appeared weathered beyond its years, yet it retained a dignified bearing that abuse couldn't erase."
A Hellfire missile fired from an American drone killed Anwar al-Awlaki on Friday, ending a two-year hunt for a radical cleric who had called on his followers to attack the U.S. any way they could.
Some details of the strike are sketchy. U.S. officials and the Yemeni Defense Ministry both confirmed that a drone had fired on a convoy of cars that was carrying Awlaki in northern Yemen. They said it was a joint operation, but it is unclear what role the Yemeni military played in the attack.
In writer Michael Ondaatje's mind, the "cat's table" is where the undesirables sit in a boat's dining room. It's for the hecklers, the lowly ones and the ones farthest away from power. And it's also where you'll find the narrator of Ondaatje's new novel, Michael, an 11-year-old who's on a 21-day voyage from Sri Lanka to London all on his own.
He and his companions — two other boys who are travelling alone — live by only one rule: to every day do at least one thing that is forbidden.
Upon the feds' recommendation, Kentucky Transportation Cabinet bridge inspectors are double-checking bridges with high-strength steel components to ensure that any critical findings have been appropriately identified and addressed. The Federal Highway Administration, in a nationwide technical advisory, recommended reviews of inspection records and, if necessary, follow-up inspections of bridges containing welded components of “T-1” steel – a type at issue in the forced closure of the Interstate 64 Sherman Minton Bridge between Louisville and New Albany, Ind.

With all the recent turmoil in the Middle East, one piece of news that has been overlooked is the revelation that the Obama administration approved the sale of 55 deep earth penetrator bombs to Israel in 2009.
The two-year-old transaction was recently reported by Newsweek. No U.S. officials have talked openly about why the bunker busters were provided to Israel but speculation falls most heavily on a single target.
