Let's take a look at alternative energy now. There's growing interest and investment in the process of extracting oil from algae and turning it into fuel for vehicles and airplanes. It requires a lot of water, nutrients and land. And a new report from the National Research Council says that will make it challenging to turn algae into a sustainable source of energy.
Ron Briggs, a member of the Board of Supervisors in El Dorado County, Calif., and his father helped expand the state's death penalty in 1978. Now Briggs wants the death penalty repealed and replaced with life without parole. Renee Montagne speaks with Briggs about his shift from death penalty supporter to death penalty opponent.
Paul Ryan is not just Mitt Romney's vice presidential running mate. He is also a member of the House of Representatives from Wisconsin, of course, and a candidate for another term. And while he's spending a lot of time on the presidential campaign trial, the seven-term congressman is also spending lots of money to hold onto his district in southern Wisconsin.
Concerns about problems at the polls appear to be greater and coming earlier than usual this election year. Already, mysterious phone calls in Florida and Virginia have told voters they can vote by phone — which they cannot do.
And until this week, there were anonymous billboards in Ohio and Wisconsin warning that voter fraud is a felony — which it is.
There are more ways than ever to watch TV programs on the Internet, from Netflix and Amazon to Hulu. But many viewers discover that watching TV on the Web can be frustrating. Their favorite show might suddenly stop, stutter and be replaced by a note that reads "buffering." The problem is lack of bandwidth: The data that is the video just can't squeeze through the wires and onto the screen.
Tanzania has been identified as the leading exporter of illegal ivory in recent years. An estimated 10,000 elephants are being slaughtered in the country annually. Here, elephants walk in the Serengeti National Reserve in northern Tanzania in 2010.
Wildlife rangers in Tanzania came across this elephant that had been killed for its ivory. Tanzania says it wants to prevent the slaughter of elephants, but rangers are poorly paid and are responsible for monitoring vast game reserves in the East African country.
On Thursday, July 29, 1880, Doyle wrote, "Came across a most extraordinary natural snow house, about 12 feet high, shaped like a beehive with a door and a fine room inside in which I sat. Traveled a considerable distance, and would have gone to the Pole, but my matches ran short and I couldn't get a smoke."

On June 15, 1880, Arthur Conan Doyle wrote a vivid sentence in his diary. It read, "The only difference in the weather is that the fog is thicker and the wind more utterly odious and depraved."
Knowing that he was the creator of Sherlock Holmes, you might think Doyle is referring to the thick London fog drifting outside the windows of 221B Baker Street. But this sentence was written years before the first Holmes novel and it describes a considerably harsher environment — the thick fog and depraved wind of the Arctic, where Doyle traveled when he was 20.
Gone from this year's presidential campaign are most mentions of climate change, environmental pollution, or green jobs. Former Gov. Mitt Romney, the GOP presidential nominee, prefers to call attention instead to the country's continuing dependence on foreign energy sources.
"I will set a national goal of North American energy independence by the year 2020," Romney declared in August.
The line is now a standard part of Romney's stump speech, and he repeated it in his first two debates with President Obama.
With 13 days left until the Nov. 6 election, President Obama and his Republican challenger, Mitt Romney, both included trips to Iowa and Nevada on their schedules. Each tried to fire up his supporters and cast doubts about the other to gain an advantage in a race that appears essentially tied.
At rallies in Davenport, Iowa, and Denver, both swing states where the election is fluid, Obama trotted out attack lines he's used in recent days against the former Massachusetts governor.
