Harvad researcher David Rans said the most successful behavior proved to be cooperation. The groups that rewarded the most earned about twice as much in the game as the groups that rewarded the least. And the more a group punish themselves the lower it's earnings. The group with the most punishment earned 25 percent less than the group with the least punishment .The study appeared last month in the Journal Science. The other study involved children .It was presentd last month in California at a conference on violence and abuse. Reseachers used intelligent tests given to two groups, More than 800 children were ages 2-4 the first time they were tested. More than 700 children were ages 5 to 9.

Many people think the search for cleaner energy leads only to renewable resources like sun, wind and water. But it also leads to a fossil fuel(化石燃料). Natural gas is considered the cleanest of the fossil fuels, the fuels created by plant and animal remains over millions of years. Burning it releases fewer pollutants（污染物质）than oil or coal. The gas is mainly methane（沼气，甲烷）. It produces half the carbon dioxide （二氧化碳）of other fossil fuels. So it may help cut the production of carbon
gases linked to climate change. Russia is first in what are called "proved reserves" of natural gas. The United States is sixth. Over the years, big oil and gas companies recovered much of the easily reached supplies of gas in America. They drilled straight down into formations where gas collects. As these supplies were used up, big drillers looked for similar formations in other countries.

Two recent studies have found that punishment is not the best way to influence behavior. One shows that adults are much more cooperative if they work in a system based on rewards. Researchers at Harward University in the United States and Stockholm school of economics in Sweden did the study. They had about two hundred college students play a version of the game known as the prisoners dilemma. The game is based on the attention between the interests of individual and group. The students play in groups of four. Each player could win points for the group so they would all gain equally. But each player could also reward or punish each of the other three players and cost to the punisher.

But now the industry is taking a new look. Companies are developing gas supplies trapped in shale rock two to three thousand meters underground. They drill down to the shale, then go sideways and inject high-pressure water, sand or other material into the rock. This causes the
rock to break, or fracture, releasing the gas. Huge fields of gas shale are believed to lie under the
Appalachian Mountains, Michigan and the south-central states. Gas shale exploration is being done mainly by small to medium sized companies. Eric Potter is a program director in the Bureau of Economic Geology at the University of Texas at Austin.
