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.

“Long time no see” is a very interesting sentence. When I first read this sentence from an American friend’s email, I laughed. I thought it was a perfect example of Chinglish.

Obviously, it is a word-by-word literal translation of the Chinese greetings with a ruled English grammar and structure! Later on, my friend told me that it is a standard American greeting. I was too thrilled to believe her. Her words could not convince me at all. So I did a research on google.com. To my surprise, there are over 60 thousand web pages containing “Long time no see.” This sentence has been widely used in emails, letters, newspapers, movies, books, or any other possible places. Though it is sort of informal, it is part of the language that Americans use daily. Ironically, if you type this phrase in Microsoft Word, the software will tell you that the grammar needs to be corrected.

Nobody knows the origin of this Chinglish sentence. Some people believe that it came from Charlie Chan’s movies. In the 1930s, Hollywood moviemakers successfully created a world wide famous Chinese detective named “Charlie Chan” on wide screens. Detective Chan likes to teach Americans some Chinese wisdom by quoting Confucius. “Long time no see” was his trademark. Soon after Charlie Chan, “Long time no see” became a popular phrase in the real world with thanks to the popularity of these movies.

Some scholars refer to America as a huge pot of stew. All kinds of culture are mixed in the stew together, and they change the color and taste of each other. American Chinese, though a minority ethnic(少数民族的成员) group in the United States, is also contributing some changes to the stew! Language is usually the first thing to be influenced in the mixed stew.

You can have some other examples besides adoptions from Chinese, such as pizza from Italian, sushi from Japanese, and déjà vu from French etc. There is a long list! Americans do not just simply borrow something from others. They will modify it and make it their own, so you would not be surprised to find a tofu and peanut butter hamburger in a restaurant, or to buy a bottle of iced Chinese green tea with honey in a grocery store. Since Americans appreciate Chinese culture more and more nowadays, I believe more Chinese words will become American English in the future. In this way the American stew keeps adding richness and flavor.
