    If your dog looks pleased to see you—it is probably because it loves the particular way you smell.

    The scent (气味)of a familiar human apparently lingers like perfumein the animal's brain—where it causes an instinctive emotional response, research reveals.

    Our scent acts on a part of the canine (犬科的) brain associated with reward and the strongest reactions are produced by humans that pets know best, say scientists in America.

    Gregory Bern, of Emory University in Atlanta, said, “While we might expect that dogs should be highly tuned to the smell of other dogs, it seems that the 'reward response' is reserved for their humans. When humans smell the perfume of someone they love, they may have an immediate, emotional reaction that's not necessarily cognitive (认识的). So is it in dogs. But since dogs have a more sensitive smell than humans, their responses would likely be even more powerful than the ones we might have. In our experiment, however, the owners of the dog were not physically present. The canine brain responses were being caused by something distant in space and time. It shows that dogs' brains have these mental representations of us that persist when we're not there.”

    The experiment involved 12 dogs of various kinds by brain scans while five different scents were placed in front of them. The scent samples (样本)came from the subject (接受试险者) itself, a dog the subject had never met, a dog living in the subject's household. The familiar human scent samples were taken from someone else from the house other than the handlers during the experiment, so that none of the scent donors were physically present.

    The results showed all five scents gained a similar response in parts of the dogs brains involved in detecting smells. Responses were significantly stronger for the scent of familiar humans, followed by that of familiar dogs. The findings showed dogs reacted strongest to the scent of familiar humans even when they were not there. Pets trained as help or therapy dogs showed greater brain activity than the other dogs in the test.

    Researchers say the findings could improve the way to select animals helping wounded old soldiers or disabled people.

    Newborns begin to develop language skills long before they begin speaking. And, compared to adults, they develop these skills more quickly. People have a hard time learning new languages as they grow older, but babies have the ability to learn any language easily.

    For a long time, scientists have tried to explain how such young children can learn the complicated grammatical rules and sounds of a language. Now, researchers are getting a better idea of what's happening in the brains of the tiniest language learners. This new information might help kids with learning problems as well as adults who want to learn new languages. It might even help scientists who are trying to design computers that can communicate like people do.

    Most babies go “ma ma” by 6 months of age, and most children speak in full sentences by age 3. For many years, scientists have wondered how the brains of young children figure out how to communicate using language. With help from new technologies, scientists are now finding that babies begin life with the ability to learn any language. They get into contact with other people, listen to what they say and watch their movements very closely. That is why they quickly master the languages they hear most often.

    Studies show that, up to about 6 months of age, babies can recognize all the sounds that make up all the languages in the world. Starting at around 6 months old a baby's brain focuses on the most common sounds it hears. Then, children begin responding only to the sounds of the language they hear the most.

    In a similar way older babies start recognizing the patterns that make up the rules of their native language. For example, English children who are about 18 months old start to figure out that words ending in “-ing” or “-ed” are usually verbs, and that verbs are action words.

    SILVER SPRING, MARYLAND — Student engagement (参与) is a goal in schools everywhere. A teacher in the Washington suburbs has found a way to engage and motivate students — by ringing rhythm and fun to mathematics. The approach works well especially for students who speak English as a second language.

Making math fun

The voice heard in the video belongs to mathematics teacher Jake Scott. Most of the performers are his students. "I use rap because it is something that appeals to the students, and also because music aids memory," Scott explains.

    Scott started using rap videos three years ago. So far he has produced nine, including

Scott started using rap videos three years ago. So far he has produced nine, including YouTube favorites Triangle Experts and Quadratic Formulatic, which have been viewed tens of thousands of times. "It is fun and the whole process is something that students appreciate," Scott says.

    Empowering students

    Blair High School principal Renay Johnson is a big supporter. She even appears in Scott's latest video, Undefined Expressions.

"Mr. Scott is very motivating and engaging for students," Johnson notes. "He enjoys what he does. As you know he engages students and mathematics through music. But he is also our wrestling coach. He also sponsors National Honor Society. And he is also a director of after school sports academy. I am lucky to have him here as a teacher."

    Scott was recognized as an outstanding educator last year by the Montgomery County Council. He was also honored as 2011 teacher of the year by an African-American civil rights organization.

    Jake Scott says he wants mathematics to be something that students look forward to learning. And he says the results will help them on a path to college and a career.

Each day, 10-year-old Seth asked his mom for more and more lunch money. Yet he seemed skinnier than ever and came home from school hungry. It turned out that Seth was handing his lunch money to fifth grader, who was threatening to beat him up if he didn't pay.

Most kids have been made fun of by a brother or a friend at some point. And it's not usually harmful when done in a playful and friendly way, and both kids find it funny. But when teasing becomes hurtful, unkind, and constant, it crosses the line into bullying and needs to be stopped.

Bullying is intentional torment(折磨)in physical or psychological ways. It can range from hitting, name-calling and threats to blackmailing(勒索)money and possessions. Some kids bully others by deliberately separating them and spreading rumours about them. Others use social media or electronic messaging to make fun of others or hurt their feelings.

It's important to take bullying seriously and not just brush it off as something that kids have to tolerate. The effects can be serious and affect kids' sense of safety and self-worth. In severe cases, bullying has contributed to tragedies, such as suicides and school shootings.

Kids bully for a variety of reasons. Sometimes they pick on kids because they need a victim—someone who seems emotionally or physically weaker, or just acts or appears different in some way—to feel more important, popular, or in control. Although some bullies are bigger or stronger than their victims, that's not always the case.

Sometimes kids bully others because that's the way they've been treated. They may think their behavior is normal because they come from families or other settings where everyone regularly gets angry and shouts or calls each other names.

Unless your child tells you about bullying—or has visible injuries—it can be difficult to figure out if its happening.
