Do you like spicy food?

    What's your opinion on spicy food? Some people cannot handle even the smallest amount of chili-red pepper-in their dinner while others can't get enough of it.

    Scientists have long been puzzled by why some people love chili while others loathe it. Plenty of research has been done on the subject, dating as far back as the 1970s. Previous results showed that a love of chili is related to childhood experiences, and cultural influences affect our taste buds too. But the latest study has found that a person's love of spicy food may be linked to his or her personality more than anything else, CBC News reported.

    'We have always assumed that liking drives intake-we eat what we like and we like what we eat. But no one has actually directly bothered to connect these personality traits with intake of chili peppers,' said Professor John Hayes from Pennsylvania State University, who led the study.

    But before you look at the study, you should first know that “spicy” is not a taste, unlike sour, sweet, bitter and salty. It is, in fact, a burning sensation that you feel on the surface of your tongue. This got scientists thinking that maybe a love of spicy food is brought about by people's longing for thrill, something they usually get from watching action movies or riding a roller coaster.

    In the study, 97 participants, both male and female, were asked to fill out questionnaires about certain traits of their personality, for example, whether they like new experiences or tend to avoid risks. They were then given a glass of water with capsaicin, the plant chemical that makes a chili burn, mixed into it.

    By comparing the answers to the questionnaire and what participants said they felt about the spicy water, researchers found that those who tended to enjoy action movies or take risks were about six times more likely to enjoy the spicy water.

    Interestingly, we used to believe that the reason some people can withstand spicy food is that their tongues have become less sensitive to it. However, this latest study has found otherwise. “It's not that it doesn't burn as badly, it's that you actually learn to like the burn,” Hayes explained.

    Against the assumption that forest fires in Alaska, Canada and Siberia warm the climate, scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.

    This finding suggests that taking steps to prevent northern forest fires to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forests in these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over next several centuries as a result of a longer fire season. Sunlight taken in by the earth tends to cause warming, while heat mirrored back into space tends to cause cooling.

    This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat.

    Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone（臭氧）levels increased, and ash from the fire fell on far-off sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling.

    “We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere.” Scientists tracked the change in amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicated, 0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases, but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.

    I discovered that inside the-wonderful box lived an amazing person whose name was Information Please. There was nothing she did not know.

    One day my mother went out. I accidentally hurt my finger when I was playing with a hammer. I walked around the house sucking my finger, finally seeing the telephone. Quickly I dragged a chair over and climbed up.

    “Information Please, ”I spoke into the receiver. A click or two and a small clear voice spoke into my ear. “Information.”

    “I hurt my finger…”I cried into the phone.

    “Isn't your mother home?” came the question.

    “Nobody's home but me.” I sobbed.

    “Are you bleeding?” the voice asked.

    “No,” I replied, “I hit my finger with the hammer and it hurts.”

    “Can you open your icebox?” she asked. I said I could.

    “Then take a little piece of ice and hold it to your finger.” said the voice.

    After that, I called “Information Please” for everything. I asked her for help with my geography and she told me where Philadelphia was. She helped me with my math. She told me her name was Sally.

    Then, there was the time my pet canary（金丝雀）died. I called “Information Please” and told Sally the sad story. “Why is it that birds sing so beautifully and bring joy to all families, only to end up as a pile of feathers?” She listened, then said quietly, “Paul, always remember that there are other worlds to sing in.” Somehow, I felt better.

    One day when I called “Information Please” again, a different voice answered “Information.”

    I asked for Sally. “Are you a friend?” she said.

    “Yes,” I answered.

    “I'm sorry to have to tell you this,” she said. “She died five days ago.” Before I could hang up she said, “Wait a minute. Did you say your name was Paul?”

    “Yes.”

    “Well, Sally left a message for you. The note said, ‘Tell him I still say there are other worlds to sing in. He'll know what I mean.'” I thanked her and hung up. I knew what Sally meant.

Dear Koko,

    I've learned about you from my amazing teacher. I think it's fun that you can communicate with us humans by using the sign language. I've spent a lot of time watching you in different videos and love you from the bottom of my heart.

    It's heartbreaking to learn about all of the cruel things done to gorillas (大猩猩). In Africa, for example, the killers use guns to kill your fellows for meat. They don't understand the influence their actions are having on gorillas. Another thing is the loss of gorillas' natural home, which is caused by the improved infrastructure such as building roads and airports. When we cut down trees, you become homeless. We take away your shelter and sources of food, leaving you with very little chance of survival.

    Some of my classmates are writing to the relevant departments about these serious problems. Hopefully these letters will make a difference during your lifetime. Over the past three months, my class has been researching on gorillas, and I've learned so many things. For example, I've learned that you have a lot of feelings similar to mine and you are always so careful with everything you do. I think that you are really worth saving.

    We've come up with many ideas to help you and your fellows. One of the best ideas is to communicate with the President of the World Bank and have him give more financial support to the organizations for gorillas. Another idea is to make public laws on the killers. I also think we need to keep educating people about gorillas.

    I love writing to you and hope you can understand how important you've become to our class. Would it be too much to ask for a return letter?

    My senior years, I can't believe it is almost over. Now when I look back, it was stressful, but exciting, the ball, graduation, and then of course, college.

    I started applying for my college months before Christmas. My parents told me it would be smart if I set up interviews and tours. But I wasn't motivated. I wanted to go to college, but I didn't want to deal with the stress.

    As the days flew by, my applications lay on my desk just as I had left them three months before. “You are wasting valuable time,” my parents complained. Sweeping away the gathered dust on the applications, I worked on them every Sunday until I finished. Next came writing the essays. I had many ideas, but every school had different requirements. I changed them until I was pleased. Finally, everything was underway.

    Now I just had to wait. In March, I started receiving letters of rejection. I began to think that I had set myself up for disappointment. I had a letter from Salem State College starting that they wanted to see my grades before they made their decision. Yes! At least someone wanted to consider me. At the beginning of April, I received a letter from Keens State. Those opening words: “We regret to inform you…” made me sit down and cry. I had lost all hope. Then I heard from Plymouth State. Not my first choice, but…I had been accepted. Maybe if I get my grades up, I can choose another school…

    The college application hurt me deeply. All my friends had dozens of schools to choose from. I guess my parents were right. High school grades are undoubtedly important to your future plans. If I could do it all over again, I would take it more seriously.
