With dramatic courtroom testimony, attorneys for Michael Jackson's doctor have dropped the bombshell they've been hinting at for months — an expert opinion accusing the singer of causing his own death.

In the harsh, remote wilds of the Canadian tundra, a wolverine scampers up to a polar bear snoozing near the shore of the Hudson Bay. The bear rises and makes a half-hearted charge, driving away the fierce, badger-like animal.

Italy saw its borrowing costs rise to a euro-era high on Friday in a sale of euro7.9 billion ($11.09 billion) in government debt, a sign that investors remain nervous about the country's prospects despite a grand European plan to fight the debt crisis.

The interest rate demanded by investors to lend the Italian government 10-year money topped 6 percent in Friday's auction, the highest level since the launch of the euro, and surpassing the 5.86 percent paid in a similar debt auction a month ago. Demand exceeded the amount on offer 1.27 times, a relatively weak outcome.
