　　An artist in Oakland, California is using his skills to help the homeless. Greg Kloehn builds very small shelters that make life on the streets a little more comfortable. The structures offer the homeless some safety and protection from bad weather. Each little house also has wheels on the bottom so it can go wherever its owner goes.
　　Greg Kloehn has given away at least 20 tiny houses. Several are on the roadside near an active railroad. On a recent day, Mr. Kloehn stops at one to visit Oscar Young. The two men hug. Inside his little shelter Mr. Young gets relief from cold nights on the streets. Mr. Kloehn also visits Sweet-Pea, another friend who also lives in one of the little homes the artist built. She says it keeps her safe and protects her belongings.
　　In the mornings, Mr. Kloehn searches the streets for building materials. He gathers what he can and takes it to his studio. There, he puts the houses together. Empty coffee bags become roof material. A washing machine door and refrigerator part become windows. Nails, screws and the stice hold all the pieces together. The artist also attaches a small electrical device to the house. The device is powered by the sun.
　　Some of the people living on the streets once had normal houses of their own. But some of the people say they have learned to live with less and they are thankful to that man.
　　Mr. Kloehn says his work is not a social project. He says he is just someone using his skills to help his homeless neighbors.

　　Researchers in Hungary have confirmed something many dog owners have long suspected: that canines understand our feelings.
　　Using a Magnetic Resonance Scanner, or MRI, scientists found that when it comes to emotions, dogs’ brains are similar to those of humans. Dogs are usually not relaxed in a lab environment, but with a little petting and lots of treats they can be trained to sit still even in an MRI scanner. That’s how researchers in Hungary’s ELTE University were able to get images of their brains at work.
　　Research fellow Attila Andics says it helped them better understand the dogs’ relationship with humans. “We have known for a long time that dogs and humans share similar social environment, but now our results show that dogs and humans also have similar brain mechanisms（大脑机制）to process social information,”said Andics.
　　After training 11 dogs to stay motionless while their brains were scanned, the researchers checked their neurological（神经系统的）responses to about 200 emotionally significant sounds, from whining and crying to playful barking and laughing. They then compared the responses from human subjects. They found striki
