According to Alice Park in “Lack of Sleep Linked to Heart Problems,” she highlights the strong connection between few sleep and heart problems. The research of the University of Chicago recently has showed that one hour less on average each night can increase coronary calcium by sixteen percent. In other words, the fewer hours people sleep at night, the more calcium contains in the heart arteries. Vessels will become crisp and breakable. As a result, it may trigger serious problems such as heart attack or stroke when these deposits rupture and block vessels in the heart or brain. It can even cause atherosclerosis and death.
There are more and more modern people who don’t get enough sleep because of many changes of their life style. White-collar workers are busy at their business while students are busy with their academic performances. Therefore, many new diseases of civilization have showed up since the development of technology and science. Some people used to think that going to bed behind schedule has little influence on their health; they will only get dark circles under their eyes after staying up late. However, it has great effect on our bodies and inner system. Not only will people feel tired but they will be the high risk group of heart attack, high cholesterol, and hypertension, etc.
In my opinion, the new discovery is very important to me. It warns me of stopping burning the midnight oil from now on. I am surprised as well as afraid after reading the news. I should finish my homework and study it earlier. If I can distribute my time much more properly, I will not become the high risk group of heart and liver illnesses. In conclusion, we should get enough sleep in order to be healthy and energetic. (298 words)

Reaction Article #11: Women 'may face greater HIV risk'
Name: Wendy Cheng (49712053)

From: BBC NEWS
My Reactions:
According to the news “Women ‘may face greater HIV risk’,” the new researches which are done by American and UK scientists show that even people try their best to prevent themselves from getting AIDS, the fatal HIV virus is more easier to penetrate into layer of skin beyond our imagination. Especially for women, it is more dangerous for them to be infected by HIV after revealing the fact that the scary virus can breach even healthy vaginal tissue.
People are used to think that there are three common reasons for human to get AIDS. One is unprotected sex between man and woman, another is sharing as well as reusing syringes or needles, and the other is perinatal transmission from mother to child. Besides, HIV is most likely going through cuts or sores in the vaginal tract. However, the scientists in Chicago found that HIV could move quickly between the skin cells when they are about to be shed. Therefore, people have new understanding about HIV invasion of the female vaginal tract.
As far as I am concerned, scientists should find out new prevention strategies to block the entry of HIV through a woman’s genital skin by developing biological technology. The most effective way to prevent AIDS presently is still condoms. The new research reinforces the need for women to avoid unprotected sex unless their partner's health is known. I really feel sad to the death that is brought by AIDS throughout the world. We have to do our best to prevent the virus from spread wider on Earth. The governments worldwide should also learn some lessons from the research. (269 words)

Reaction Article #10: Mystery Pyramid Built by Newfound Ancient Culture?

From: National Geographic News
My Reactions:
According to Alexis Okeowo in “Mystery Pyramid Built by Newfound Ancient Culture,” the archaeologists in Mexico have found some stone sculptures recently which indicate that there was an unknown culture that likely built a mysterious pyramid. They also discovered some ancient artifacts, being totally different from what they had found before, show that Mexico had developed various cultures at the same time but diverse region. Moreover, the pyramid’s proportion shows that this “new” culture seems to exist between other two cultures in ancient Mexico- Teotihuacan and Tula (Toltec). However, many controversies have been discussed by archaeologists due to contrasting excavations. Although archaeologists don’t know much information about the new ancient culture in Mexico, it is for sure that ancient cultures in Mexico are independent from each other.
As far as I am concerned, the article is novel as well as attractive because I am really fund of archeology personally. It not only introduces new archaeological evidence but also several features of antique artifacts some famous ancient cultures in Mexico. I can learn more knowledge about the ancient world. Pictures of the ancient Mexican pyramid in the article are quite distinct from common pyramids in Egypt. I change my opinion about Mexico after reading the article. I used to think that there wasn’t any special ancient culture in Central America; nevertheless, there were indeed many creative cultures long time ago. In my opinion, we should care more about minor cultures in Central America and Africa instead of well-known cultures in Asia or Europe. (252 words)

Reaction Article #9: Getting paid for Your A's
Name: Wendy Cheng (49712053)
Date: 12/05/2008
From: Time
My reactions:
There have been many high-school graduates who loan before starting their colorful college life lately. Parents are worried about their children’s future because their children are going to be in debt without having jobs.
However, in accordance with Kate Torgovnick in “Getting Paid for Your A’s,” she describes a website called Gradefund.com, which is launched by a Columbia Business School student and entrepreneur Michael Kopko. Gradefund.com can help top-performing students to ease off their loan crunch. As long as they upload their transcripts each semester, they can earn money if they get an A. Nevertheless, the way that Gradefund provide money is different from other common institutions. It makes students find their own sponsors such as relatives or friends and ask them for money whatever they want for each A. Besides, Gradefund also mails students a check if they reach $100 in donations. Although the website has caused some controversies, it still becomes popular in America now.
In my opinion, the website may indeed solve the problem that students are accumulating debt. But it can lead to some problems. For example, it may support rich students instead of students who really need money but they are not rich enough. In addition, it encourages students cheat in exams in order to get good grades. The method using in Gradefund is interesting and innovative: even so, it has much to improve. Maybe the government should do something to help students, future leaders of our society, study happier rather than worrying about their life. In conclusion, whether Gradefund.com is a wonderful website depends on how students use it properly. (266 words)
