Music for Humans and Humpback Whales   

    As researchers conclude in Science, the love of music is not only a universal feature of the human species, but is also deeply fixed in complex structures of the human brain, and is far more ancientthan previously suspected.

    In the articles that discuss the field of bio-musicology, the study of the biological basis for the creation and appreciation of music, researchers present various evidence to show that music-making is at once an original human "business", and an art form with skillful performers throughout the animal kingdom.

    The new reports stress that humans hold no copy right on sound wisdom, and that a number of nonhuman animals produce what can rightly be called music, rather than random sound. Recentin-depth analyses of the songs sung by humpback whales show that, even when their organ would allow them to do otherwise, the animals converge on the same choices relating to sounds and beauty, and accept the same laws ofsong composition as those preferred by human musicians, and human ears, everywhere.

    For example, male humpback whales, who spend six months of each year doing little else but singing, use rhythms (节奏) similar to those found in human music and musical phrases of similar length—a few seconds. Whales areable to make sounds over a range of at least seven octaves (八度音阶), yet they tend to move on through a song in beautiful musical intervals, rather than moving forwards madly. They mix thesounds like drums and pure tones in a ratio (比例) which agrees with that heard in much western music. They also usea favorite technique of human singers, the so-called A-B-A form, in which a theme is stated, then developed, and then returned to in slightly revised form.

    Perhaps most impressive, humpback songs contain tunes that rhyme. "This suggests that whales use rhyme in the same way we do: as a technique in poem tohelp them remember complex material," the researchers write.

    Darek Fidyka, a 38-year-old Bulgarian, had been paralyzed (瘫痪的) from the chest down for four years after a knife attack. Scientists from Britain and Poland took cells from his nose, transplanted (移植) them into his back and re-grew his spinal cord (脊髓). Now he can walk and even drive a car. The doctors were delighted but said it was the first step in a long journey.

    The breakthrough came after 40 years of research by Professor Geoff Raisman, who found that cells had the possibility to repair damage to nasal (鼻腔的) nerves, the only part of the nervous system that constantly re-grows. “The idea was to take something from an area where the nervous system can repair itself and put it into an area that doesn't repair itself,” Professor Raisman said.

    Polish doctors injected (注射) the nasal cells into Mr Fidyka's spinal cord above the injury and used some nerves from his ankle to form a bridge across the damaged tissue. The nasal cells appear to have caused the spinal nerves to repair themselves.

    Professor Raisman achieved this with rats in the late 1990's, but this is his greatest success. “I think the moment of discovery for me was Christmas in 1997 when I first saw a rat, which couldn't control its hand, put its hand out to me. That was an exciting moment, because I realized then that my belief that the nervous system could be repaired was true.”

    Doctors chose the easiest case for their first attempt—it might not work for others. But there is a real sense of hope that an idea once thought impossible has been realized.

    David Nicholls, who helped provide money for the breakthrough, said information about the breakthrough would be made available to researchers across the globe.

    “What you've got to understand is that for three million paralyzed people in the world today, the world looks a totally brighter place than it did yesterday,” he said.

    In the spring of my career, I found myself questioning the choice of my life's work. The students did not appear to be motivated; the paperwork was overwhelming (巨大的) and the constant changes of educational direction were discouraging. But I just could not bring myself to do anything else. “Next year,” I would say, “next year I will switch jobs, make more money and have far less stress.” Next year just never came. I am now in my forties. And while I am no longer in the classroom or at the schoolhouse, I remain an educator. It finally dawns on me that there is no other profession that will let me change children's minds and have an impact on their future. For every student that finally “got it”, for every new teacher that said, “You inspired me to stay,” I get the raise that has never quite made it to my paycheck.

    I was on a plane recently and the flight attendant asked my name. When I told him, he said, “I knew that was you! You taught at my elementary school. You made me take my cap off in the building and told me I was handsome.” He then paused and said, “I think I kept my hat on until you saw me, just so I could get that compliment (赞美). Thank you for making me feel special.”

    We have now entered an age where nothing is private and secrets are hard to keep. Your “friends” are counted by simply clicking a button. Face-to-face interactions are seen by many as unnecessary and time-consuming. Of course, we can do anything online, including teaching and learning. But I guess I am just old school. I want to look into your eyes when the answer finally dawns on you.

    The modern Sainsbury Wing on the western side of the building houses 13th- to 15th-century paintings, and artists include Duccio, Uccello, Van Eyck, Lippi, Mantegna, Botticelli and Memling.

    The main West Wing houses 16th-century paintings, and artists include Leonardo da Vinci, Cranach, Michelangelo, Raphael, Bruegel, Bronzino, Titan and Veronese.

    The North Wing houses 17th-century paintings, and artists include Caravaggio, Rubens, Poussin, Van Dyck, Velazquez, Claude and Vermeer.

    The East Wing houses 18th- to early 20th-century paintings, and artists include Canaletto, Goya, Turner, Constable, Renoir and Van Gogh.

    Nearest underground stations: Charing Cross (2-minute walk), Leicester Square (3-minute walk), Embankment (7-minute walk), and Piccadilly Circus (8-minute walk).

    The morning had been a disaster. My tooth was aching, and I'd been in an argument with a friend. Her words still hurt: “The trouble with you is that you won't put yourself in my place. Can't you see things from my point of view?” I shook my head stubbornly-and felt the ache in my tooth. I'd thought I could hold out till my dentist came back from holiday, but the pain was really unbearable. I started calling the dentists in the phone book, but no one could see me immediately. Finally, at about lunchtime, I got lucky.

    “If you come by right now,” the receptionist said, “the dentist will fit you in.”

    I took my purse and keys and rushed to my car. But suddenly I began to doubt about the dentist. What kind of dentist would be so eager to treat someone at such short notice? Why wasn't he as busy as the others?

    In the dentist's office, I sat down and looked around. I saw nothing but the bare walls and I became even more worried. The assistant noticed my nervousness and placed her warm hand over my ice-cold one.

    When I told her my fears, she laughed and said, “Don't worry. The dentist is very good.”

    “How long do I have to wait for him?” I asked impatiently.

    “Come on, he is coming. Just lie down and relax. And enjoy the artwork,” the assistant said.

    “The artwork?” I was puzzled.

    The chair went back. Suddenly I smiled. There was a beautiful picture, right where I could enjoy it: on the ceiling. How considerate the dentist was! At that moment, I began to understand what my friend meant by her words.

    What a relief!
