Conflict is on the menu tonight at the café La Chope. This evening, as on every Thursday night, psychologist Maud Lehanne is leading two of France's favorite pastimes, coffee drinking and the “talking cure”. Here they are learning to get in touch with their true feelings. It isn't always easy. They customers - some thirty Parisians who pay just under $2 (plus drinks) per session - care quick to intellectualize (高谈阔论)，slow to open up and connect. “You are forbidden to say ‘one feels,' or ‘people think',” Lehane told them. “Say ‘I think,' ‘Think me'.”

A café society where no intellectualizing is allowed? It couldn't seem more un-French. But Lehanne's psychology café is about more than knowing oneself: It's trying to help the city's troubled neighborhood cafes. Over the years, Parisian cafes have fallen victim to changes in the French lifestyle - longer working hours, a fast food boom and a younger generation's desire to spend more time at home. Dozens of new theme cafes appear to change the situation. Cafes focused around psychology, history, and engineering are catching on, filling tables well into the evening.

The city's psychology cafes, which offer great comfort, are among the most popular places. Middle-aged homemakers, retirees, and the unemployed come to such cafes to talk about love, anger, and dreams with a psychologist. And they come to Lehanne's group just to learn to say what they feel. “There's a strong need in Paris for communication,” says Maurice Frisch, a cafe La Chope regular who works as a religious instructor in a nearby church. “People have few real friends. And they need to open up.” Lehanne says she'd like to see psychology cafes all over France. “If people had normal lives, these cafes wouldn't exist”, she says, “If life weren't a battle, people wouldn't need a special place just to speak.” But them, it wouldn't be France.

    NANJING, Nov. 4 (Xinhua) — Xi Jinping and Ma Ying-jeou will shake hands in their historic meeting scheduled in Singapore on Saturday, head of the Taiwan Affairs Office of the State Council said on Wednesday.

    The two-part meeting includes one session open to the media and another behind closed doors, said Zhang Zhijun, who is also head of the Taiwan Work Office of the Communist Party of China (CPC) Central Committee, when interviewed at the Zijinshan Summit for Entrepreneurs across the Taiwan Strait.

    According to Zhang, Xi and Ma, as "leaders of the two sides" of the Taiwan Strait, will exchange views during the closed-door meeting.

    After the meeting, press conferences will be held by both sides. Later, the two leaders are expected to attend a dinner, said Zhang.

    Zhang said the meeting will lift cross-Strait communication to a new high.

    The landmark meeting is a breakthrough in face-to-face exchange and communication between the leaders across the Taiwan Strait after the relationship became strained following the events of 1949.

    Zhang said the meeting will improve mutual trust and allow for an exchange of opinions on handling the cross-Strait ties.

    In addition, the meeting will help strengthen the 1992 Consensus(共识), which was reached in talks between the two sides in 1992 and recognizes the one-China principle, and safeguards the peaceful development of cross-Strait ties, according to Zhang.

    Zhang added that the scheduled meeting will also benefit regional peace and stability.

    Also at Wednesday's summit, Chiang Pin-kung, former chairman of the Taiwan-based Straits Exchange Foundation, hailed the upcoming meeting between the two leaders as a milestone for cross-Strait ties.

    Chiang told the media that he believed the meeting will give a boost to the peaceful development of cross-Strait ties.

    You may know the Eiffel Tower as one of the most famous man-made monuments in the world, and you'd be absolutely right! Read on to learn about the history of the great Eiffel Tower.

    Travelers from around the world flock(蜂拥)to Paris, France, to visit the Eiffel Tower, making it the most visited paid monument in the entire world! In fact, in 2010, the Eiffel Tower welcomed its 250 millionth visitor!

The history of the Eiffel Tower

    The Eiffel Tower was named after the engineer Gustave Eiffel, whose company designed and built the famous monument. Construction began in January of 1887 and was completed in only two years. Their plan was to finish the tower in time to be the entrance arch for the World's Fair in 1889. This fair celebrated the 100^th anniversary of the French Revolution, which took place from 1789 to 1799.

The height competition

    Located on the Champs de Mars, the tower is the tallest structure in Paris. It was the tallest man-made structure in the world for 41 years until the Chrysler Building in New York surpassed(超过) it. Then the spire(塔尖) on the top of the tower was added, raising its height to 17 feet taller than the Chrysler Building. It is now 1,063 feet tall! There are two replicas(复制品) of the Eiffel Tower in the world: a half scale model at the Paris Hotel in Las Vegas and a full-sized monument of a similar (but not exact) design in Tokyo, Japan.

Three shades of wonder

    Some pictures make the Eiffel Tower look like a dark iron color. But it is, in fact, bronze. Not only that, but the tower is actually painted three different shades to make it appear even taller: darkest on the bottom and lightest on the top.

    Ever wondered whether punishment actually makes people cooperate (合作)? A team of scientists created an experiment to figure it out and the results were pretty unexpected.

    To understand what they found, you have to know why these scientists were studying punishment. They were trying to figure out why people cooperate when it's often so easy to profit at others expense. Why don't friends steal from each other? Why do parents bother to feed their children? If the answer to these questions is obvious to you, congratulations, you are ahead of scientists. They're still trying to figure it out.

    In this experiment, researchers had 225 Chinese students play a game, where if the students cooperated, they'd all get a number of points. But if one defected (变节) and everyone else cooperated, the defector would get a lot of points, and the cooperators would lose out. This game represents a lot of real life situations where you struggle with a decision: work together and do OK, or run off with the rewards, ruining everybody else's day.

    This is actually a pretty ordinary economic experiment. But the researchers added two changes to see if they could mimic(糢拟)the real world better. Change one: some students played many rounds together, so they'd learn who they could trust. Change two: people could punish each other, sacrificing a point or two to destroy another player's score.

    In the end, the researchers found that playing multiple rounds made people cooperate more, which definitely mimics human society. But the whole punishment thing led to a surprise: punishing didn't actually make people cooperate more. In fact, it made them cooperate less.

    So the scientists still don't know why people cooperate, though it looks like it has more to do with groups sticking together than it does with punishment.

    A six-wheeled robot travels underground in Hefei to discover warning signs of faults inside the pipeline network, "It looks like a toy car at first, but it's much more complicated than that," said Xu Mao, the robot's operator.

    The pipeline robot, developed by Wuhan Easy-Sight Technology, is made up of four parts — crawler, camera, cable reel, and controller. A full charge can enable the robot to work for four to five hours, covering a distance between 800 and 1,000 meters in the underground p ipeline.

    The robot made its appearance last month in Shushan District. It will carry out inspections of the underground pipeline network stretching 150 kilometers." Whether the pipe is leaking, damaged or blocked, we can clearly see its situation through high-definition(高清晰度的)cameras fixed into the robot, " said Qi Chuanshuai from the provincial construction engineering and testing institute.

    The real-time data including video images of the pipe will be up loaded and displayed on a computer. "If we find any problems, we stop the robot and record the flaws," Xu said. "We report the faults to local government, who will arrange the repair as soon as possible."

    With the rapid develop merit of cities, it is becoming increasingly difficult to manage underground pipelines. Among all the difficulties, discovering faults in the sewage (污水)and rainwater pipelines comes first. Many other cities such as Wuhan, Nanjing, Shenzhen, and Shanghai are using the robots to inspect their pipelines, the robot's developer said.

    Equipped with environmental detection sensors, the robots can monitor temperature and damp, poisonous gases, oxygen levels and smoke density, while providing color diagram in real time. "Compared with human workers, robots are able to enter smaller pipes and are immune (有免疫力的)to poisonous gases in sewage pipes," said Ge Shengli from Shushan District' s city management company." No digging is required and there is no need to interrupt traffic," Ge added.

Pieter Bruegel's iconic 1565 painting The Harvesters hangs at The Metropolitan Museum of Art. The work shows people harvesting wheat nearly as tall as they are. "Nowadays, however, if you walk through a wheat field, you basically see that wheat is about knee-height. The reduced height is essentially a consequence of being bred (培育) along with genes for increasing production to feed a growing population," biologist De Smet explained.

De Smet said wheat was just one example of how historical artwork could allow us to track the transformation of food crops over time. He teamed up with art historian Vergauwen, a friend since childhood, to document such art work around the world. They have been mainly looking at things where they can spot changes in shape, color and size.

Their interest in plants in artwork began with a visit to the Hermitage Museum, where they noticed an odd-looking watermelon in an early-17th-century painting. It appeared to be pale and white on the inside. Biologist De Smet assumed the painter had done a poor job. But art historian Vergauwen had a different idea. "No, this is one of the best painters ever from that era. So if he painted it like that, that's the way it must have looked like," he explained.

Other paintings revealed that both red and white watermelons were grown during the 17th century. "With all the genetic knowledge we now have, we can look at how something comes about in more detail," said De Smet. "For example, until the 18th century, European strawberries appeared tiny in paintings. They then grew in size as they were crossbred with North American varieties."

Ultimately, the team hopes to create an online research database of historical plant artwork. They seek the contributions of art enthusiasts around the world via the social media. "However," Vergauwen reminds, "if you're going to use, for example, Picasso to try and understand how a pear looked in the early 20th century, you might be misled."
