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 behaviour. 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.

Earlier this morning I e-mailed an old friend, Mark. We have been out of touch for 12 years, but the 36 is a wonderful thing. Finding his e-mail address 37 less than a minute. He is working on his doctoral paper in western America.
Mark and I met at a summer 38 that we both attended. I went every year from the time I was 8 or 9 until I was 15. I don’t 39 exactly, but I think Mark was there for as many years as I was.
We lived close to each other and 40 saw each other around the campsite, but not often. Mostly we stayed together for a week or two in the 41 and wrote letters back and forth during the rest of the first few years. I still have all of his letters in a box somewhere. I come across them occasionally and 42 to sit down and read through them, but I never have. He was a 43 and precious friend to me, and I am deeply 44 that we have drifted so far apart.
Mark was a very kind and incredibly bright and funny 45 . He loved Monty Python — I mean he was a fanatic(狂热者), and could 46 entire movies from memory. He was one of those kids who 47 such a unique and powerful mind 48 they never quite fit into the main stream of life. 49 Mark, who I believe realized that, never seemed to care about it. When I knew that Mark was working on his 50 (on a highly intellectual and fairly mysterious and difficult topic), I thought, “Well yes, of course.” He is just where I would
51 him to be.
I wonder if he will write me back. I wonder if he will be 52 by where I am. I wonder whether he and I can be 53 again, or whether these years have left us with 54
in common. I wonder whether he can ever be the man I 55 , or only remain the boy I knew.
