4、"I have super powers," a girl named Megan whispers to her doctor in a recent TV show. That's her explanation for how she's able to stand painful cuts and being hit with a base-ball bat--all without feeling any pain.

Across the world about a few hundred people suffer from one of many disorders (紊乱) that make them completely unable to feel pain from the time they are born.

Now a new form of this disorder has been recognized among people from northern Pakistan, and scientists have tracked down the changed gene responsible for the condition. Their study could help researchers gain a better understanding of how pain works and may help them develop new medicine that may reduce pain with fewer side effects.

Researchers discovered the latest version of the disorder when they found a young street performer in Pakistan, sticking knives through his arms. Then they found six other people from three families in the same area who also had the disease.

These people were able to feel hot and cold, sense pressure, and could tell sharp objects touching their skin from blunt ones. They were all believed to be of only average intelligence. But none of them felt any pain. Surprisingly, the families were unrelated, but all of the sufferers had changes to the same gene. The changed gene causes a protein (蛋白质) to form part of a channel that is undoubtedly important for human sense of pain.

Early childhood can be awful for people without feeling any pain. They can bite endlessly on their tongues and fingers during teething, stick their fingers in their eyes, or suffer major injuries without noticing. The six people studied for the Nature paper all had injuries to their lips or tongues from biting themselves when they were young.

 You are standing under the most famous neon lights in the centre of London, waiting to cross the road. Suddenly the traffic stops. You hear the distant sounds of cheering, clapping and shouting. Then, like a multi-colored train, 2, 000 people with wheels on their feet zoom past you. You have just witnessed the London Skate, a twice weekly roller-skate(溜旱冰) event that attracts people in their hundreds and thou-

sands London. Skate is a completely free tour of the streets of London -the only condition is that you go along on roller-skates. It lasts between two and three hours and by the end of it you have skated between 10 and 12 miles. The skate snakes round the streets of London along several different routes. Many of the routes pass by tourist attractions such as Buckingham Palace and Big Ben. Marshals (交通协调员) go ahe-  of the group, stopping the traffic so that people can skate as safely as possible. Everyone is welcome to take part and people from the age of 4 to 63 years old join the fun. "I love it very much, it is amazing. It feels just like a carnival (狂欢节)," said Celeste Beverage regular skater.

Many big cities in Western Europe and in the US now ha- ve a regular group skating event. The biggest skates take place in Paris and Munich and tens of thousands of fans show up on warm evenings. "Roller-skating is taking over the world," said Julian Grenoble, a 25-   year-old ski shop employee from London. Grenoble went to the Paris-Roller (Paris skate) regularly until he moved to Britain.

"It's so exciting to skate in Paris. Everyone skates so fast and puts in their best efforts!" he said. The Paris Roller is well known because of the huge attendance, the presence of marshals and the police protection.
