It was the summer of 1965. Deluca, then 17, visited Peter Buck, a family friend. Buck asked DeLuca about his plans for the future. "I' m going to college, but I need a way to pay for it," DeLuca recalls saying. "Buck said, 'You should open a sandwich shop. '"

That afternoon, they agreed to be partners. And they set a goal: to open 32 stores in ten years. After doing some research, Buck wrote a check for $ 1,000. DeLuca rented a storefront (店面) in Connecticut, and when they couldn't cover their start-up costs, Buck kicked in another $ 1,000.

But business didn't go smoothly as they expected. DeLuca says, "After six months, we were doing poorly, but we didn't know how badly, because we didn't have any financial controls." All he and Buck knew was that their sales were lower than their costs.

Deluca was managing the store and going to the University of Bridgeport at the same time. Buck was working at his day job as a nuclear physicist in New York. They'd meet Monday evenings and brainstorm ideas for keeping the business running. "We convinced ourselves to open a second store. We figured we could tell the public, 'We are so successful, we are opening a second store.' "And they did--in the spring of 1966. Still, it was a lot of learning by trial and error.

But the partners' learn-as-you-go approach turned out to be their greatest strength. Every Friday, DeLuca would drive around and hand - deliver the checks to pay their suppliers. "It probably took me two and a half hours and it wasn't necessary, but as a result, the suppliers got to know me very well, and the personal relationships established really helped out." DeLuca says.

And having a goal was also important. "There are so many problems that can get you down. You just have to keep working toward your goal," DeLuca adds.

DeLuca ended up founding Subway Sandwich, the multimillion -dollar restaurant chain.

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（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 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 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.
