Q: Science has a lot of uses. It can reveal laws of nature, cure diseases, make bombs, and help bridges to stand up. Indeed science is so good at what it does that there's always a temptation to drag it into problems where it may not be helpful. David Brooks, author ofThe Social Animal, The Hidden Sources of Love, Character, and Achievement, appears to be the latest in a long line of writers who have failed to resist the temptation.

Brooks gained fame for several books. His latest bookThe Social Animal, however, is more ambitious and serious than his earlier books. It is an attempt to deal with a set of weighty topics. The book focuses on big questions: What has science revealed about human nature? What are the sources of character? And why are some people happy and successful while others aren't?

To answer these questions, Brooks surveys a wide range of subjects. Because of this, you might expect the book to cover a variety of facts. But Brooks has structured his book in an unusual, and perhaps unfortunate way. Instead of introducing scientific theories, he tells a story, within which he tries to make his points, perhaps in order to keep the reader's attention. So as Harold and Erica, the hero and heroine in his story, live through childhood, we hear about the science of child development and as they begin to date we hear about the theory of sexual attraction. Brooks carries this through to the death of one of his characters.

On the whole, Brooks's story is acceptable if uninspired. As one would expect, his writing is mostly clear and, to be fair, some chapters stand out above the rest. I enjoyed, for instance, the chapter in which Harold discovers how to think on his own. While Harold and Erica are certainly not strong characters, the more serious problems withThe Social Animallie elsewhere. These problems partly involve Brooks's attempt to translate his tale into science.

Q: (CNN) -- Three radio DJs in Kenya are going six days without food while broadcasting non-stop to promote peaceful voting in a country that was nearly torn apart after its last election five years ago.

Ghetto Radio presenters Mbusii, Solloo and Essie have been locked inside a "glass house" in central Nairobi since Wednesday, as part of the station's annual Serious Request Kenya event.

This year's theme is "Vote4Peace Vote4Kenya," ahead of the East African country's elections on March 4 2013. The vote will be the first since ethnic violence engulfed the country after disputed elections in December 2007, leaving more than 1,000 people dead and 350,000 displaced, according to the Kenya Red Cross.

Three days into the challenge, DJ Solloo is in good spirits -- despite the lack of food.

"I'm a bit hungry," he laughingly admits, "but we have to do this -- it's a pretty good feeling."

Solloo, whose real name is Solomon Njoroge, says Kenya cannot afford a return to post-election violence. Last time around, he says, he was a victim of the bloody unrest that swept his town of Eldoret, one of the fighting hotspots in Kenya's Rift Valley province.

Solloo says that back then he had to spend more than two weeks with limited food supplies while camping at a police station for safety.

"This country cannot afford to go back to that time," says Solloo from the glass house, a few moments before going on air. "I decided to come here because we have to push for this message to be a part of every Kenyan. It has to be every Kenyan's initiative to know that peace is more than just the absence of war."

Q: Editor's note: This story originally appeared on CNN.com on October 20. Barack Obama mentioned Ann Nixon Cooper on Tuesday in his presidential victory speech.

Ann Nixon Cooper, 106 years old, lived during a time when blacks and women did not have the right to vote.

ATLANTA, Georgia (CNN) -- Ann Nixon Cooper, 106 years old, has seen presidents come and go in her lifetime and has outlived most of them. On a sunny fall morning, she left her weathered but well-kept Tudor home in Atlanta, Georgia, to vote early -- this time for Barack Obama.

The African-American centenarian remembers a time not long ago when she was barred from voting because of her race. Now she hopes to see the day that Obama is elected as the nation's first black president.

"I ain't got time to die," Cooper said with a smile.

"Even if he didn't win, I was happy for him just to be nominated," said the former socialite. "The first black president -- isn't that something, at 106 years old?" Watch Obama say 'Yes we can' "

At the Fulton County government center, Cooper was greeted by Atlanta Mayor Shirley Franklin.

"I thought that I would accompany her today to support her, but also to say to all people that this is a choice we have," Franklin said.

"As all Americans, we should cherish the right to vote and take every opportunity we have to vote our opinions. She is an inspiration to me personally, but she is also quite an inspiration to all Atlanta." Watch Cooper talk about her life and experiences "
