It took a little nudge, but Happy Feet the wayward penguin was indeed sent on his way home (hopefully) over the weekend.

The Associated Press has video of the moment when the little guy who ended up on a beach in New Zealand — thousands of miles from his home in Antarctica — slid into the Pacific Ocean.

When I was a kid, I assumed that in the future things would get better and better until we were all driving flying cars and playing badminton with space aliens on top of 500-story buildings. Frankly, I kind of counted on this happening. But now I don't assume that we'll just keep going up anymore.

As the 10th anniversary of the Sept. 11 terrorist attacks draws closer, we're pointing to some of the stories being told about that day and the days since.

This morning, The Wall Street Journal offers "A Battered Firm's Long Road Back." It's a look at the investment-banking firm Keefe, Bruyette & Woods, which lost more than a third of its 171 New York employees when the south tower of the World Trade Center fell.

Sen. Jim DeMint of South Carolina — who is a powerful voice in the early voting state and a Tea Party favorite — organized the forum, which started on a bit of a deflated note with news that Texas Gov. Rick Perry backed out at the last minute to deal with raging wildfires in his state.

Observation Post Mustang sits high in the mountains of northeastern Afghanistan, near the Pakistan border. At an altitude of 5,600 feet, the soldiers stationed there from the Army's 2-27th Infantry Regiment have a stunning view of the Kunar River Valley far below.

But it's not all just beautiful vistas and clean mountain air. On Sunday, the forward operating base that sits in the valley below took enemy fire.
