A scientist who developed a way to calculate(计算) how much water is used in the produciton of anything form a cup of coffee to a hamburger was awarded the 2008 Stockholm Water Prize.
Professor John Anthony Allan of the University of London in Britain won the award for introducing the idea of "virtual water(虚拟水)",a calculation method that has changed the nature of trade policy and research.
Allan has written seven books and published more than 100 papers.
The Stockholm International Water Institute said this idea is now embedded(埋藏) in the production of foods and industrial products.The institute said Allan's work had made a big effect on global trade policy and research,especially in water - scarce(缺水) regions.
"The improved understanding of trade and water management issues on local,regional and global scales are of the highest value for the successsful and sustainable(可持续的) use of water resources,"it said.
"People do not only use water when they drink it or take a shower,"the institute said. "Behind the morning cup of coffee,there are 140 liters of water that was used to grow,produce,package and ship the beans."That is about as much water as a person in England uses on average for all daily drinking and household needs.
"For a single hamburger,about 2,400 liters of water are needed.In te USA ,the average person uses nearly 7,000 liters of virtual water every day" It said that was more than three times the average use of a Chinese person.

Scientists have developed a new cancer drug. So far, they have tested it only in laboratory animals. The drug
is designed to enter and kill cancer cells, but not healthy cells.
First, the drug enters the cancer cells and stops their supply of blood. Then it releases poison to destroy the
cancer cells.
Researchers at the Massachusetts Institute of Technology(MIT) in Cambridge carried out the study. The results appeared in Nature magazine. A school report called the drug an “anticancer smart bomb”.
Ram Sasisekharan is a professor at MIT. He says that his team had to solve three problems. They had to find a way to destroy the blood vessels, then to prevent the growth of new ones. But they also needed the blood vessels to supply chemicals to _________.
So, the researchers designed a two-part “nanocell”. The cell is measured in nanometers(毫微米), or one thousand millionth of a meter.
The scientists say thay that it was small enough to pass through the blood vessels of the cancer, but it was too big to enter normal blood vessels. The surface of the nanocells also helped them to avoid natural defenses.
The scientists designed the cell as a balloon inside a balloon. They filled the outer part with a drug that caused the blood vessels to die. That cut off the blood supply and put the nanocells inside the cancer. Then, the nanocells slowly released drugs to kill the cancer cells.
The team says that the treatment killed the cancer and avoided healthy cells better than other treatments. Untreated mice with cancer survived for twenty days. The scientists say that mice with the best current treatments lived for thirty days. In this study, they say that eighty percent of the mice treated with the nanocells lived more than sixty-five days.
The scientists say that more studies are needed before the new drug can be tested in humans.
