(CNN) -- If the Day of Judgment begins Saturday, as an apocalyptic Christian radio network has predicted, the community of Rapture, Indiana, will likely take it in stride.

Perhaps that's because the souls who lived in 15 to 20 homes in the southwest corner of the state are long gone -- leaving only one family and the name Rapture on online maps.

Curious about its history, CNN called area post offices, the town hall in nearby Poseyville and the local library. Nobody had heard of Rapture, much less knew how it got its name.

But they did know of Bugtown, as the tiny community on Highway 68 is now known.

Heather Gallagher, director of Poseyville Carnegie Public Library, did a little digging and suggested a call to Bugtown's sole resident, who splits his time between Indiana and Nashville.

David Tanner gave up his law practice and moved to Nashville, where he plays upright bass and sings in groups Spaghetti Westerneers and Brazilbilly.

He owns a home, rental property and an airplane hangar in Bugtown.

"The rest is grass," said Tanner.

An atheist, Tanner is not fretting about Family Radio founder Harold Camping's prediction that Jesus Christ will return during the world's destruction and ascend into heaven with true believers.

I'm not concerned if the world doesn't end and it's all a hoax," Tanner said from Nashville Friday. "If it does (end), I've had a great time living to 46."

In nearby Griffin, Guy Carner, 77, said he is familiar with Bugtown. "It's a dot in the road." What are the answers to this following set of questions: 1. Who's the lone resident of Bugtown?
2. What's his profession that he quit?

In South America, the rich soil of the Amazon River basin in Brazil is known as "black gold". Scientists found that the secret of this rich soil was charcoal . Local people made it from animal bones and tree branches. They mixed the charcoal with the soil about 1.500 years ago.

Now, scientists in the United States have done a modern demonstration. They say charcoal fertilization offers a revolutionary way to improve soil quality for hundreds or even thousands of years.

Mingxin Guo and his team at Delavare State University heated tree leaves, corn stalks , small pieces of wood and poultry waste into "biochar" . They reported their findings at a recent meeting of the American Chemical Society in New Orleans.

Biochar could be good news for farmers with poor soil and hungry populations to feed. Professor Guo says it could even help against global warming. Intensive farming and overuse of chemical fertilizer give out carbon dioxide into the atmosphere. Biochar does the opposite, he says. It traps carbon in the ground.

The researchers planted winter wheat in containers of soil in a greenhouse -- some with biochar, some without. Professor Guo says the wheat grows much better in the pots with biochar. The soil was added two percent charcoal to. But he says even a one percent treatment will increase productivity.

The results demonstrated that biochar can increase organic matter in soil. Loss of nutrients in soil is an increasing problem worldwide as farmers try to grow more food for growing populations.

Next, the team will carry out a five-year study of biochar with spinach , green peppers and tomatoes.

Mingxin Guo says he learns about the "black gold" in Brazil from a magazine story. He explains that it was discovered in the jungle, in the area where waters flow to the Amazon, in the 1960's. But it was not until recent years that scientists began to bring public attention to it. What are the answers to this following set of questions: 1. Where is the Amazon River basin located?
2. What kind of soil if found there?
3. What is the rich soil also known as?
4. Who made the soil the way it is?
5. Using what?
6. When did they do this?
7. What country is doing modern demonstrations of this method?
8. Who is the scientist that is heading this project?
