C
When an ant dies, other ants take it out of the nest, often within an hour after its death. This behavior interests scientists and they wonder how ants know for sure--and so soon--that another ant is dead.
One scientist recently came up with a way to explain this ant behavior. Dong-Hwan Choe is a biologist, a scientist who studies animals and plants. He found that ants have a chemical on the outside of their bodies that signals to other ants, “I’m dead--take me away” when it is dead.

But there's a question to answer: As we know, if an ant is dead, it stops moving. But when an ant is sleeping or knocked unconscious, it is also not moving. However, other ants don't move the living ant out of the nest. How do they know this ant is not dead? Choe found that ants have another chemical on their bodies, which tells nearby ants something like, “Wait—I'm not dead yet” when it is not dead. Choe suspects that when an ant dies, the chemical that says, “Wait— I'm not dead yet” quickly goes away. When other ants detect the “dead” chemical without the “not dead yet” chemical, they move away the body.
To test his theory, Choe and his team put different chemicals on ants. When the scientists used the “I'm dead” chemical, other ants quickly moved the treated ant away. When the scientists used the “Wait—I'm not dead yet” chemical, other ants left the treated ant alone. Choe believes this behavior shows that the “not dead yet” chemical overrides the “dead” chemical when picked up by other ants. And that when an ant dies, the “not dead yet” chemical fades away. Other nearby ants then detect the remaining “dead” chemical and remove the body from the nest.
Understanding this behavior can help scientists figure out how to stop ants from invading new places and causing problems.

Have you ever heard the story of the four-minute mile? Many years ago, people believed that it was impossible for a human being to run a mile in less than four minutes until Roger Banister proved it wrong in1954.
What happens if you put an animal in a pond? Any animal, big or small, will swim its way through. What happens when someone, who does not know how to swim, falls in deep waters? They drown. If an animal who has not learned swimming could escape by swimming, why not you? Because you believe you will drown while the animal does not.
Have you ever wondered why the letters are organized in a particular order on hour keyboard? You might have thought it is to increase the typing speed. Most people never question it. But the fact is that this system was developed to reduce the typing speed at a time when typewriter parts would jam if the operator typed too fast.
These three cases show the power of our beliefs. There is no other more powerful directing force in human behavior than belief. Your beliefs have the power to create and to destroy. A belief delivers a direct command to your nervous system.
I used a snake in my workshops for children to show them how unrealistic some of their beliefs are. Students of a school in India, said snakes were slippery, slimy (黏糊糊的) and poisonous. After doing an exercise for changing beliefs, they handled my snake and found it to be dry and clean. They also remembered that only three types of poisonous snakes exist in India.
Did this story end the way you thought? Review your beliefs now and find out which ones you need to change.

Tabb doesn't look like a typical music teacher. But every weekday evening in the French Quarter New Orleans, he beats out the rhythm on his music stand as students play their chosen instruments.
“I'm doing my best to take young people away from harmful things,” said Tabb. His program, "The Roots of Music”, offers free music education to more than 100 students. He struggles to keep young people on the straight and narrow in the city with the nation's highest murder rate(凶杀率).
Tabb chose to target 9to14yearolds with his program. “That's a very important time in your life,” he said. “If I catch them then, I can hold onto them for at least four or five years and guide them the way that will lead them to success.”
Students meet from 4 pm to 7 pm every weekday, all year round. They work with tutors(助教) on schoolwork, practice their music and eat a hot meal before heading home. With the money provided by some people, Tabb's group is able to provide bus transportation, instruments and food for free. He calls it his “no excuse” policy. “You have no excuse why you're not here,” Tabb said. Tabb owes the success in part to the nature of music. “You're always learning something new,”he said. “That's what keeps the kids coming back every day.”
But the program isn't only about fun. “Music is about discipline (纪律),”said Tabb. He insists on good behavior and keeps kids in order with threats of situps(仰卧起坐), pushups(俯卧撑) or tasks like picking up grains of rice — but these measures aren't just punishment. Tabb wants young people to realize that music can help them build a better future. “I don't say that I'm saving lives,” he said. “I say I'm giving life — a whole different life of music.”
