Article: Against the supposition 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 the 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 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 the 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 predicted, 0.5 watts per square meter of area burned are _ 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.
Answer: result in a warming climate
.According to the new findings, taking steps to prevent northern forest fires may _ .

Article: One of the major functions of an iPhone is, of course, to play music. The iTunes app has been designed in such a way as to take advantage of the iPhone's touch screen. But what if you want to listen to music that isn't in your iTunes library, or you want to discover new music without sitting in front of computer?

(Shazam) Shazam is an innovative and free app that cures your"what was that song?"problem. It happens to all of us : we hear a song (on TV or in a store ), love it, know we have heard it before but just can't remember what it is called . With Shazam you don't need to. Just hold your iPhone up and through its microphone, Shazam will identify the album, artist and song title for you. You can then either purchase the song in iTunes or search it on other apps for streaming. How cool is that?
Answer: iPhones

Article: As the first woman Chancellor in German's history, Angela Merkel topped magazine's list of "The World's 100 Most Powerful Women" in 2006, 2007, 2008, and 2009.She has even been compared to Margaret Thatcher and many people called her "Iron Lady". Merkel was born in Hamburg, West Germany, on July 17, 1954.Six weeks after she was born, her family moved to Templin. As a small child, Merkel quickly learned to speak but took longer to walk. "I was a stupid person when it came to moving?" Merkel said. "A normal person could do something naturally, but I had to think about it in my mind and practice." As a teenager, she was the top student and graduated from high school with perfect marks. In 1973, Merkel went to the University of Leipzig, where she studied physics. At 32, she got her doctor's degree in physics. She _ _ in 1989.In her first big political job as Minister for the Environment in 1994, her scientific background and strong will proved very useful. In 2005 she became Germany's Chancellor. She has been reelected to a second term as German Chancellor on September 27, 2009. Through her political career, Merkel's persistence and patience helped her a lot. "She's bright and openminded," said Hubert Markl. "She is the person who wants to know exactly what is going on, and how never giving up will influence our society and future."
