Whenever the discussion turns to saving money in Medicare, the idea of raising the eligibility age often comes up.

"I don't think you can look at entitlement reform without adjusting the age for retirement," Sen. Lindsey Graham, R-S.C., said on ABC's This Week last Sunday. "Let it float up another year or so over the next 30 years, adjust Medicare from 65 to 67."

Once upon a time when a car company introduced a new car, it was a new new car.

But at this year's L.A. Auto Show, you won't see any revolutionary new rides — at least not on the outside. You'll find the same sameness in your grocery store parking lot. A lot of cars look alike. Why is that?

"What they're relying on to distinguish these cars from one another is not so much the mechanical pieces of them or the design," says Brian Moody of Autotrader.com. "They're selling sort of a lifestyle or an experience or a philosophy."

Just a few years ago, rhino poaching appeared to be more or less under control.

Shootings were relatively rare, and about 75 percent of the world's rhinos lived in South Africa, a country that has taken extensive efforts to protect them.

Just 13 rhinos were reported killed worldwide in 2007. But the figure has been surging in recent years and has already hit 588 so far this year, according to conservation groups.

An estimated 25,000 rhinos remain in Africa.

In Washington's latest game of chicken, President Obama is counting on voters who see things his way to give him the edge in his quest to get congressional Republicans to accept tax increases on the nation's wealthiest as part of any fiscal cliff deal.

To energize those voters, the president is ramping up a series of campaign-style events meant to educate the public about the stakes, as he sees them, of letting the Bush-era tax cuts for middle-class Americans expire if no agreement is reached by year's end.

Sofas and other cushy furniture often contain chemicals intended to reduce the risk of fire. But those chemicals may pose health risks of their own, and some researchers are trying to build the case for getting them out of the house altogether.

Eighty-five percent of couches tested in a new study contained at least one flame-retardant chemical in the foam cushioning.

Determined not to be excluded from the post-election bipartisan talk of passing immigration legislation, the Congressional Hispanic Caucus on Wednesday rejected two Republican proposals while outlining its own priorities.
