    Last year DeepMind's AlphaGo programme took on and beat two of the world's best players of the Chinese game of Go（围棋）-an unbelievable achievement seen as a milestone in the development of artificial intelligence (A). That programme was trained by first giving it vast amounts of data from amateur and professional games.

    The new AlphaGo Zero began with a blank board and nothing but the rules of Go and set about playing against itself. Within three days it was so advanced that it took on the previous version, which had taken months to develop, and defeated it by a hundred games to zero.

    DeepMind says that creating knowledge from first principles without learning from human expertise（专门技能）is an important step in developing artificial intelligence. The company's founder Demis Hassabis said this breakthrough could help in real world problems such as designing new drugs or discovering new materials.

    In 1997, Garry Kasparov was defeated by Deep Blue, a computer program written by IBM, running on a supercomputer. This was the first time that a ruling world chess champion was defeated by a computer program in tournament conditions. Superficially, AlphaGo's win against Lee Sedol can be compared to Deep Blue's win against Gary Kasparov, which happened almost 20 years ago. So: what's the big deal? We have to understand the differences between chess and Go.

    In chess, each player begins with 16 pieces of six different types. Each piece of type moves differently. The goal of the game is to seize the other player's king. Go starts with an empty board. The goal of the game is to gain as much territory（领地）as possible.

    Although the rules of Go might appear simpler than those of chess, the complexity of Go is higher. Also, games usually last longer for lots of moves. A typical game in Go might last for 150 moves vs.80 in chess.

    As any plane passenger will confirm, a crying baby is almost impossible to ignore, no matter how hard you try. Now scientists believe they may have worked out why. A baby's cry pulls at the heartstrings(扣人心弦)in a way while other cries don't, researchers found.

    Researchers found that a baby's cry can trigger unique emotional responses in the brain, making it impossible for us to ignore them—whether we are parents or not. Other types of cries, including calls of animals in great pain, fail to get the same response…suggesting the brain is programmed to respond specifically to a baby's cry.

A team of Oxford University scientists scanned the brains of 28 men and women as they listened to a variety of calls and cries. After 100 milliseconds — roughly the time it takes to blink (眨眼) —two parts of the brain that respond to emotion lit up. Their response to a baby's cry was particularly strong. The response was seen in both men and women—even if they had no children.

    Researcher Dr Christine Parsons said, "You might read that men should just notice a baby and step over it and not see it, but it's not true. There is a special processing in men and women, which makes sense from an evolutionary(演化的)view that both men and women would be responding to these cries." The study was in people who were not parents, yet they are all responding at 100ms to these particular cries, so this might be a fundamental response present in all of us regardless of parental status.

    Fellow researcher Katie Young said it may take a bit longer for someone to recognize their own child's cries because they need to do more "fine-grained analysis". The team had previously found that our reactions speed up when we hear a baby crying. Adults performed better on computer games when they heard the sound of a baby crying than after they heard recordings of adults crying.

    Anyone watching the autumn sky knows that migrating birds fly in a V formation, but scientists have long debated why. A new study finds that these big－winged birds carefully position their wingtips and flap(拍动) at the same rate, probably to catch the upward movement of air and save energy during flight.

    There are two reasons birds might fly in a V formation: It may make flight easier, or they're simply following the leader. Squadrons(中 队) of planes can save fuel by flying in a V formation, and many scientists suspect that migrating birds do the same. Models that treated flapping birds like fixed－wing airplanes show that they probably save energy by drafting off each other, but currents created by airplanes are far more stable than those coming off of birds.

    Just as aerodynamic(气动力) calculations would predict, the birds positioned themselves to fly just behind and to the side of the bird in front, timing their wing flaps to catch the uplifting eddies(涡流). When a bird flew directly behind another, the timing of the flapping reversed(相反) so that it could minimize the effects of the downdraft coming off the back of the bird's body. “We didn't think this was possible,” Usherwood says, considering that the difficult achievement requires careful flight and incredible awareness of one's neighbors. “Perhaps these big V formation birds can be thought of quite like an airplane with wings that go up and down.”

    The findings likely apply to other long－winged birds, such as pelicans and geese, Usherwood says. Smaller birds create more complex wakes(尾波) that would make drafting too difficult. The researchers did not attempt to calculate the birds' energy savings because the necessary physiological measurements would be too invasive for an endangered species. Previous studies show that birds can use 20% to 30% less energy while flying in a V.

    Scientists do not know how the birds find that aerodynamic sweet spot, but they suspect that the animals line themselves up either by sight or by sensing air currents through their feathers. In future studies, the researchers will switch to more common birds, such as pigeons or geese. They plan to investigate how the animals decide who sets the course and the pace, and whether a mistake made by the leader can ripple through the rest of the flock to cause traffic jams.

    On April 8th, 2013, the world felt sorry because of the death of former British Prime Minister, Margaret Thatcher, who died at the age of 87. Besides being the country's longest leader (1979-1990) in the 20th century, she was the first woman to lead Britain. She worked hard and did well in her work, so she was called" Iron Lady".

    Whatever you think of Margaret Thatcher, the thing everyone does agree on is that she was a woman with great decisions. When she took over Britain in 1979, she led a country that was in economic trouble. She faced a lot of problems because of the poor economic position.

    In order to make the country become strong again, Ms. Thatcher had to make some hard and special decisions like raising interest rates and even taxes at a time when most British people were living a hard life. In this way she led Britain to run out of economic troubles.

    Early in her second term, just as things were looking a little better, she faced another problem — a strike by the British Miners Union. Once again, the Iron Lady stood her ground to stop the longest strike in the country's history.

    In 1982, Argentina said that they had owned the Falkland Islands since the 19th century. Britain, however, considered the islands to be one of their overseas dependent territories (领土). Margaret Thatcher tried to talk about the problem with Argentines. But Argentines didn't agree with her ideas, so Ms. Thatcher did what any strong leader would do — send in the British Army. It took 74 days, and on 14th June 1982, the Argentine army finally failed and Britain controlled the Falkland Islands again.

    When Ms. Thatcher resigned in 1990, she left behind a country that was very strong. Unluckily, during the last few years of her life, something was wrong with her mind. She hardly remembered anything that was happening around her and even what she had done during her wonderful lifetime.

    The movie The Wizard of Oz has thousands of fans around the world. But back in 1939 when the film opened, audiences were not particularly fond of it. It was only a modest box office success. It was nominated for Best Picture at that year's Academy Awards, but so were nine other great films. It lost out to Gone with the Wind.

    The Wizard of Oz really gained an audience when it was broadcast regularly on TV. That began in the 1950s. The film's plot follows young Dorothy who is knocked unconscious during a tornado. She dreams about following a Yellow Brick Road through the Land of Oz to the Emerald City. She wants to meet the Wizard of Oz who lives there. He's the only one who can help her to return home to Kansas. Along the way she makes friends with the Scarecrow, the Tin Man and the Cowardly Lion. They help her and her dog Toto overcome the Wicked Witch of the West!

    According to the Library of Congress, The Wizard of Oz is the most watched movie of all time. What is it about the film that appeals to people? It includes themes that people can relate to. Through most of the movie Dorothy is trying to get home to Kansas. When she finally gets to go, she speaks the words, "there's no place like home." People identify with that thought. Home is the welcoming place where they feel secure.

    At the beginning of the film, Dorothy sings of a place "over the rainbow." There, the dreams that you dare to dream really do come true. So while home is a great place, dreaming about something different is all right too.

    The Wizard of Oz also deals with courage. Dorothy learns that true courage isn't being unafraid. It's facing danger when you are afraid. Her friends face plenty of danger to rescue her.

    As one of the true classics of American literature, The Wizard of Oz has stirred the imagination of young and old alike for over four generations. Celebrate the 80th year of this fabulous film by watching it again.
