When an ant dies, other ants move the dead insect out. Sometimes, the dead ant get moved away very soon—within an hour of dying. This behavior is interesting to scientists, who 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. Choe found that Argentine ants have a chemical on the outside of their bodies that signals to other ants, “I’m dead—take me away.”
But there’s a twist to Choe’s discovery. Choe says that the living ants—not just the dead ones—have this death chemical. In other words, while an ant crawls around, perhaps in a picnic or home, it’s telling other ants that it’s dead.
What keeps ants from dragging away the living ants?Choe found that Argentine ants have two additional chemicals on their bodies, and these tell nearby ants something like, “Wait—I’m not dead yet.” So Choe’s research turned up two sets of chemical signals in ants: one says, “I’m dead,” and the other set says, “I’m not dead yet.”
Other scientists have tried to figure out how ants know when another ant is dead. If an ant is knocked unconscious, for example, other ants leave it alone until it wakes up. That means ants know that unmoving ants can still be alive.
Choe suspects that when an Argentine ant dies, the chemical that says “Wait-I’m not dead yet” quickly goes away. Once that chemical is gone, only the one that says “I’m dead” is left. “It’s because the dead ant no longer smells like a living ant that it gets carried to the graveyard, not because its body releases(释放) new unique chemicals after death,” said Choe. When other ants detect the “dead” chemical without the “not dead yet” chemical, they drag away the body.
Understanding this behavior may help scientists figure out how to stop Argentine ants from invading new places and causing problems. Choe would like to find a way to use the newly discovered chemicals to spread ant killer to Argentine ant nests.
The ants’ removal behavior is important to the overall health of the nest. “Being able to quickly remove dead individuals and other possible sources of disease is extremely important to all animals living in societies, including us,” says Choe. “Think about all the effort and money that we invest daily in waste management.”

A
An eight-year-old child heard her parents talking about her little brother. All she knew was that he was very sick and they had no money. Only a very expensive operation could save him now and there was no one to lend them the money.
When she heard her daddy say to her tearful mother, “Only a miracle can save him now,” the little girl went to her bedroom and pulled her money from its hiding place and counted it carefully.
She hurried to a drugstore with the money in her hand.
“And what do you want?” asked the salesman. “It’s for my little brother,” the girl answered. “He’s really, really sick and I want to buy a miracle.” “Pardon?” said the salesman.
“My brother Andrew has something bad growing inside his head and my daddy says only a miracle can save him. So how much does a miracle cost?” “We don’t sell a miracle here, child. I’m sorry,” the salesman said with a smile.
“Listen, if it isn’t enough, I can try and get some more. Just tell me how much it costs.”
A well-dressed man heard it and asked, “What kind of a miracle does your brother need?”
“I don’t know,” she answered with her eyes full of tears. “He’s really sick and mum says he needs an operation. But my daddy can’t pay for it, so I have brought all my money.”
“How much do you have?” asked the man. “$ 1.11, but I can try and get some more,” she answered.
“Well, what luck,” smiled the man. “$ 1.11, the price of a miracle for little brothers.”
He took up the girl’s hand and said, “Take me to where you live. I want to see your brother and meet your parents. Let’s see if I have the kind of miracle you need.”

Tess was eight years old. Her little brother Andrew was very sick and their parents were completely out of money. She heard Daddy say to her tearful Mother, “Only a miracle can save him now.”

Tess took her money and made her way six blocks to Rexall’s Drug Store.

“And what do you want?” the chemist asked in an annoyed tone of voice. “I’m talking to my brother from Chicago whom I haven’t seen for ages.”

“Well, I want to talk to you about my brother,” Tess answered back in the same annoyed tone. “He’s really sick. He has something bad growing inside his head and my Daddy says only a miracle can save him now. So how much does a miracle cost?”

“We don’t sell miracles here, little girl. I’m sorry but I can’t help you,” the chemist said, softening a little.

“Listen, I can help you.” The chemist’s brother was a well-dressed man. He asked Tess, “What kind of miracle does your brother need?”

“I don’t know,” Tess replied. “Mommy says he needs an operation. But my Daddy can’t pay for it, so I want to use my money.”

“How much do you have?” asked the man from Chicago. “One dollar and eleven cents,” Tess answered. “And it’s all the money I have, but I can get some more, if I need to.”

“Well,what a coincidence (巧合),” smiled the man. “A dollar and eleven cents - the exact price of a miracle for your little brother. Take me to where you live. Let’s see if 1 have the kind of miracle you need.”

That man was Dr. Carlton Armstrong, a surgeon in neurosurgery (神经外科). The operation was completed without charge and it wasn’t long until Andrew was home again and doing well.
