Mascots(吉祥物) are great ambassadors(大使)for sporting events. You may remember the five cute "Fuwa(福娃)”dolls from the 2008 Beijing Olympics. Now, get ready to meet two new mascots.

On Sept 17, there was a giant panda with a white helmet named “Bing Dwen Dwen(冰墩墩)” and a red lantern baby called“Shuey Rhon Rhon”(雪容融) as the two mascots for the 2022 Beijing Winter Olympic and Paralympic Games(冬奥会和残奥会). These two mascots show Chinese culture. The giant panda is Chinese national treasure, and the red lantern is an important element(元素) of Chinese New Year celebrations. What’s more, the panda's helmet(头盔) stands for modern society and its white color means the snow and ice of winter sports.

“The two mascots includes elements of traditional Chinese culture and a modern international style, as well as emphasizing the characteristics of ice and snow sports," Beijing 2022 Games executive president(执行主席) Chen Jining told Xinhua.

These two mascots show Chinese characteristics(特征). And their names express Chinese people's understanding of the Olympic spirit(精神). “Bing” and “Shuey” mean “ice” and “snow” in English. “Dwen Dwen” means “honest and lively” and “Rhon Rhon” has the meanings of “tolerance(包容)”and “integration(融合)”.

“They can express the Olympic spirit. They warmly invite people all over the world to come and visit China." Chen told Xinhua.

TOKYO, JAPAN-- What do you do when you see a cockroach? Do you hit it with a newspaper? Do you step on it?

When researchers at Tokyo University see a cockroach,they take the remote control and make the cockroach turn around,run left or right,or go forward.These scientists are changing the cockroaches into robots. Each cockroach has a very small pack that has a microprocessor in it. Then researchers can send signals from the remote control to the packet. The signals control the movements of the cockroaches.

Why does anyone want to control a cockroach? "Insects can do many things that people can't,” says Isao Shimoyama, head of robot research at Tokyo University. In a few years, he says, these robot insects will carry very small cameras. They will be able to move through earthquake rubble to look for people or move under door to find information about someone.

This may seem strange, but the Japanese government thinks the research is very important. The government is giving the scientists $5 million for this research.

First, the researchers breed hundreds of cockroaches. They use only the American cockroach because it is bigger and stronger than other cockroaches. Then they choose the best cockroaches and remove their wings and antennae. They put small packets where the antennae were. The packets weigh about three grams, or about two times the weight of the cockroaches themselves. “Cockroaches are very strong,” says Ralph Holzer,who is a researcher at Tokyo University. "They can lift 20 times their own weight.”

With a remote control, the scientists send signals to the packets. When a cockroach gets the signal, it moves. The problem is that the cockroaches don' t always move in the right direction.
