Have you ever considered why you begin yawning too when you see someone yawn? Or how hard it is to be among people laughing and not laugh yourself? Well, apparently it's because we have mirror neurons (神经元）in our brains.

    Put simply, the existence of mirror neurons suggests that every time we see someone else do something, our brains imitate it whether or not we actually perform the same action. This explains a great deal about how, we learn to smile, talk, walk, dance or play sports. But the idea goes further: mirror neurons not only appear to explain physical actions, they also tell us that there is a biological basis for the way we understand other people.

    Mirror neurons can undoubtedly be found all over our brains, but especially in the areas which relate to our ability to use languages, and to understand how other people feel. Researchers have found that mirror neurons relate strongly to language. A group of researchers discovered that if they gave people sentences to listen to ( for example: “The hand took hold of the ball” ) , the same mirror neurons were triggered as when the action was actually performed (in this example, actually taking hold of a ball).

    Any problems with mirror neurons may well result in problems with behavior. Much research suggests that people with social and behavioral problems have mirror neurons which are not fully functioning. However, it is not yet known exactly how these discoveries might help find treatments for social disorders.

    Research into mirror neurons seems to provide us with even more information regarding how humans behave and interact. Indeed, it may turn out to be the equivalent (相等物）for neuroscience of what Einstein's theory of relativity was for physics. And the next time you feel the urge to cough in the cinema when someone else does — well, perhaps you'll understand why.

    Music is magic! Music speaks louder than words and it is a “language” that the whole world can understand. A piece of music can produce a response in the heart and mind. Like feeling an electrical current or receiving a personal radio signal, music has a spiritual effect on a person. Different kinds of music influence people in different ways.

    I have listened to music all my life. When I was twelve years old, the Beatles came to America and my whole world opened up. Maybe young people today cannot understand the influence of the Beatles when they exploded across America. Their influence changed the way we dressed, looked, acted and spoke... even our culture. The Beatles arrived in America from the UK just under three months after the assassination(暗杀) of President John Kennedy, which had put America into a great depression. And the freshness and lively spirit of the Beatles was exactly what the country needed to refresh itself.

    Music links the heart of the hearer with that of the composer. This means that it mixes the spirit of the composer with your spirit when you listen to it. And the music can take your spirit out of your body and transport you into another world. Music has a great way of touching people. Music can make you laugh, cry or shout. It's also a great source of inspiration.

    Try this one day and notice what happens: make yourself a cup of tea, sit on your sofa and play one of your favorite songs. Close your eyes, and soon you'll find yourself creating vivid mental images—matching the music that you are listening to.

    Dreams can be familiar and strange, fantastical or boring, but some dreams might be connected to the mental processes that help us learn. No one knows for certain why people dream, but some dreams might be connected to the mental processes that help us learn. In a recent study, scientists found a connection between nap-time dreams and better memory in people who were learning a new skill.

    In the study, 99 college students between the ages of 18 and 30 each spent an hour on a computer, trying to get through a virtual maze(迷宫). The maze was difficult, and the study participants had to start in a different place each time they tried — making it even more difficult. They were also told to find a particular picture of a tree and remember where it was.

    For the first 90 minutes of a five-hour break, half of the participants stayed awake and half were told to take a short nap. Participants who stayed awake were asked to describe their thoughts. Participants who took a nap were asked about their dream after sleep — and they were awakened within a minute of sleep to describe their dreams.

    Stickgold, a neuroscientist (神经科学家), to know what people were dreaming about when their eyes weren't moving, during sleep.

    Four of the 50 people who slept said their dreams were connected to the maze. Some dreamed about the music that had been playing when they were working; others said they dreamed about seeing people in the maze. When these four people tried the computer maze again, they were able to find the tree faster than before their naps.

    Stickgold suggests the dream itself doesn't help a person learn — it's the other way around. He suspects that the dream was caused by the brain processes associated with learning.

    All four of the people who dreamed about the task had done poorly the first time, which makes Stickgold wonder if the dreams show up when a person finds a new task particularly difficult. People who had other dreams, or people who didn't take a nap, didn't show the same improvement.

    Birthdays often involve surprises.But this year's surprise on the birthday of the great British playwright William Shakespeare is surely one of the most dramatic.

    On April 22,one day before his 441st birthday anniversary,experts discovered that one of the most recognizable portraits（画像）of William Shakespeare is a fake.This means that we no longer have a good idea of what Shakespeare looked like."It's very possible that many pictures of Shakespeare might be unreliable because many of them are copies of this one,"said an expert from Britain's National Portrait Gallery.

    The discovery comes after four months of testing using modern chemistry technology.The experts from the gallery say the image—commonly known as the "Flower portrait"—was actually painted in the 1800s,about two centuries after Shakespeare's death.The art experts who work at the gallery say they also used modern chemistry technology to check the paint on the picture.These checks found traces of paint dating from about 1814.Shakespeare died in 1616,and the date that appears on the portrait is 1609.

    “We now think the portrait dates back to around 1818 to 1840.This was when there was a renewed interest in Shakespeare's plays,”Tarnya Cooper,the gallery's curator（馆长）,told the Associated President.

    The fake picture has often been used as a cover for collections of his plays.It is called the Flower portrait because one of its owners,Desmond Flower,gave it to the Royal Shakespeare Company.

    “There have always been questions about the painting,”said David Howells,curator for the Royal Shakespeare Company.“Now we know the truth,we can put the image in its proper place in the history of Shakespearean portraiture.”

    Two other images of Shakespeare,are also being studied as part of the investigation and the results will come out later this month.

    Did you know that if you attach a weighed stick to the back of a chicken, it walks like a dinosaur?

    No, you did not know(or care to know) such things, but now you do! Thanks to this year's winners of the 12 Noel Prize! Now in is 251h year, the lg Nobel is the goofy younger cousin of the honored Nobel Prize. It applauds achievements in the fields of medicine, biology, physics, economies.literature.etc. Every September at Harvard University, awards are presented in 10 categories that change year to year, depending on - according to the organization - what makes the judges "laugh, then think".

    The ceremony officially begins when audience members launch paper airplanes at an assigned human target on the stage, then speakers only have 60 seconds to present their research. In previous year, the one-minute rule was imposed by a young girl - nicknamed Miss Sweetie Poo -who would go up to the platform and repeat the words: "Please stop, I'm bored." in a sharp tone until the speaker left the stage.

    Fortunately for candidates though, the Ig Informal Lectures are held afterwards on Saturday to give presenters more time to explain the crazy things they're working on.

    The research can seem more like the brainchildren of teenage boys than of respectable adults. Justin Schmidt won the physiology Ig for creating the "Sting(蛰) Pain Index," which rates the pain people fell after getting stung by insects. Smith pressed bees against 25 different parts of his body until they stung him. Five stings a day for 38 days, Smith concluded that the most painful sting locations were the nose and the upper lip. Ouch.

    As silly as they sound, not all of the Ig awards lack scientific applicability, A group of scientists from 12 different counties won in the medicine category for accurately diagnosing patients with appendicitis (阑尾炎) based on an unusual measurement: speed bumps(减速带) . They found that patients are more likely to have appendicitis if they report pain during bumpy car rides.

    All these weird experiments have just one thing in common. They're improbable. It can be tempting to assume that "improbable" implies more than that--implies bad or good, worthless or valuable, trivial or important. Something improbable can be any of those, or none of them, or all of them, in different ways. And what you don't expect can be a powerful force for not only entertaining science, but also for the boundary-pushing science we call innovation.
