Scientists have known for decades that lab rats and mice will live far longer than normal if they're fed a super-low-calorie diet, and that's led some people to eat a near-starvation diet in the hopes that it will extend the human life span, too.

But a new study in monkeys suggests they may be disappointed.

The long-awaited results of this study, which started back in 1987, show that rhesus monkeys fed a diet with 30 percent fewer calories than normal did not live unusually long lives.

Standing outside the Central Minnesota Ethanol Co-Op in Little Falls, Minn., there's not a lot going on. The pungent smell of fermentation that typically hangs in the air here is absent. And trucks piled high with corn are nowhere to be seen.

They're idled in part because of high corn prices. And it's unclear when that will change.

"Most of the industry is just breaking even in terms of profitability or actually running at slightly negative margins," says Geoff Cooper, vice president of research and analysis at the Renewable Fuels Association.

Dave Ballard got the idea of a wacky charity race while watching a YouTube video of someone slip-sliding through a slough of foam. The first 5K Foam Fest was held in the fall of 2011 in Idaho.

A year and more than a dozen events later, Ballard says his group has raised more than $10,000 for charity, with most of those funds being donated to Shared Hope International, an organization that combats human trafficking.

With Republicans dominating political news coverage from their national convention in Florida, President Obama took to the popular social news site Reddit Wednesday afternoon for a surprise Q-and-A with users.

The wide-ranging discussion touched on issues from Internet freedom to space travel to the most difficult decision of his presidency (which Obama said was sending more troops to Afghanistan).

Two Missouri farmers have been infected with a brand-new tick-borne virus that the Centers for Disease Control and Prevention is calling the Heartland virus.

The men recovered but suffered serious illness that required hospital care and weeks of convalescence. Symptoms included fever, severe fatigue, headache and nausea. Their platelet counts plummeted, but even though platelets are necessary for blood clotting, the men didn't suffer abnormal bleeding.

The U.S. and other Western countries are often trying to isolate Iran, but this week the country is in the international spotlight as it hosts a summit of 120 nonaligned nations.

U.N. Secretary-General Ban Kim-moon decided to go, ignoring the advice of Israel and the U.S. He promised to deliver a tough message, but others are skeptical, arguing that his visit plays into the hands of the Iranians and to U.N. detractors in Washington.

You're listening to ALL THINGS CONSIDERED from NPR News.

Encounters between humans and bears have risen in Western states, especially in Wyoming and Colorado. That's due largely to drought. Bears are traveling longer distances for food because the berries they usually eat have dried up.

As we hear from Aspen Public Radio's Marci Krivonen, hungry bears are turning to dumpsters, kitchen cabinets and refrigerators.

In Crow, Wiconi Wawokiya means "helping families."

The Wiconi Wawokiya, Inc. shelter — also known as Project SAFE — is on the Crow Creek Sioux Indian Reservation in central South Dakota. It serves more than 350 victims of domestic violence, sexual assault and child abuse.

"The needs are great," says the program's director Lisa Thompson-Heth. The center provides an array of services, including crisis counseling, medical assistance and legal advocacy.

Nominating the presidential and vice-presidential candidates is just part of the business conducted at a party convention. Delegates and guests also spend time attending workshops and policy sessions. And then there's the partying — lots of partying.

Two moderate Republicans — former congressmen Mike Castle of Delaware and Tom Davis of Virginia — wonder whether that wing of their party can survive. In years past the party had a component referred to as "Rockefeller Republicans" — named after former Vice President Nelson Rockefeller. The group tended to work well with middle of the road Democrats.

As Isaac continues to pound the Gulf Coast from Louisiana east through Mississippi, Republicans gathered in Tampa for their 2012 national convention continue to strike a balance between going on with their politicking and partying while trying not to look indifferent to the suffering of others.

Isaac might not be in the same league as Hurricane Katrina seven years ago, but the latest storm to batter Louisiana's Gulf Coast is punching above its weight class in more ways than one, scientists say.

Chuck Yates is a senior managing director at a private equity firm in Houston. Almost every senior energy executive in town knows him well.

A while back, Chuck learned of the Youth Development Center, a non-profit organization that inspires and equips inner city kids to achieve academic success.

Chuck organizes an annual dinner at the House of Blues where a notable energy personality is roasted by his peers. The dinner is the main source of YDC's funding.

China's latest online sensation is a Bush, but perhaps surprisingly, it's neither the 41^st or the 43^rd President of the US. In fact, Neil Bush, the younger brother of 43 and the son of 41 has become an online sensation in China after posting a joke photo on China's version of twitter.

Neil Bush was virtually unknown in China a week ago, despite being co-chairman of Beijing-based real estate company, CIIC.

This year is on track to be the worst ever for West Nile virus in the United States. Here are the latest numbers from the Centers for Disease Control and Prevention:

• 1,590 reported cases, nearly 500 more than a week ago for a rise of 44 percent.
• 889 cases, or 56 percent, involve severe neurological disease.
• 66 deaths, compared to 41 last week.

Last February, five major banks came to an agreement with the United States government that would provide $26 billion in mortgage relief aid to homeowners.

Bradley Thompson, a production manager at the Republican National Convention here in Tampa, took the opportunity this morning to propose to his girlfriend, Laura Bowman. He popped the question right in front of the big on-stage screen — on which were the words "Laura Bowman, will you marry me" and some lovely photos.

From the kiss he got in return, it appears she said yes.

There is growing international criticism over plans by Gambia's hard-line president to execute all of the country's death-row inmates within the next couple of weeks.

Gambia's leader, President Yahya Jammeh, has long faced criticism for his human rights record. In a recent speech marking the end of Ramadan, the Muslim holy month, the president vowed to put to death all prisoners facing the death penalty by mid-September, as a way to curb crime.

Camp Catch-Up, hosted by the publicly and privately supported Nebraska Children & Families Foundation, enables children separated by foster care and adoption to spend a fun-filled weekend with their brothers and sisters — at no cost to the families.

Whether campers haven't seen their siblings in a week or a year, they bond at camp as only siblings can, through activities structured to bring them together.

Thanks to Townhall.com's Guy Benson, one of the hotter stories of the morning here in Tampa seems to be that actor/director/American icon Clint Eastwood is reportedly coming to the Republican National Convention and may be the "to be announced" speaker on Thursday night's schedule.
