An Australian-based scientist announced yesterday he had made a step forward in forensic (用于法庭的) DNA testing so that an individual can be identified by a single cell.

Ian Findlay, from the Australian Genome Research Facility at the University of Queensland, said current DNA testing required 200 to 500 cells to gain a similar level of accuracy.

"What we have done has brought that down to one cell," Dr Findlay said after releasing details of his DNA testing technique at a Sydney conference.

The technology could allow investigators to pick up DNA identities from plastic cards and even build up a complete history of the people who have handled a paper document.

"You'd have to wear a space suit to stop yourself from leaving traces. You can identify cells on the paper, so you can work out where it's come from and who's touched it, "he said.

The technique could also be used to trace the thrower of a punch foam cells left behind on the skin of their victim. Even the wearing of latex gloves would not help: small cells can pass through the gloves, and the constant Row of genetic material given off by the human body would leave further evidence.

"We gained a skin cell from a document dating back 30 years and managed to gain a DNA fingerprint. DNA evidence can remain fresh for decades, perhaps even centuries," Dr Find]ay said.

"The potential for this technology to solve unsolved crimes is great, "he said.

But Dr Find]ay, named scientist of the year 'in 1998 by the European Society of Human Genetics, ,aid the new testing needed to be scientifically validated, which would take up to five years.

He said, "There are serious consequences taking on technologies too early. The public has to be sure that they have the utmost confidence in the security and court systems. "

Despite a privileged background, Katharine had to deal, while growing up, with the high demands her mother placed on her children. Katharine's love of journalism, which she shared with her father, led to her career(事業(yè)) after college at The Washington Post, the newspaper her father bought in 1933. At the Post, Katharine met Phil Graham, a young, charming lawyer who became her husband. When, in 1945, Katharine's father chose Phil over her to take over his snuggling paper, Katharine didn't object and stayed at home as a wife and mother of four.

While Phil's successful efforts to restore the Post to prominence made the Graham popular members of the Washington social scene, Katharine privately suffered tremendous pain from her husband's increasingly abusive behavior and wild mood swings caused by severe depression. When Phil committed suicide( 自殺), the 46-year-old Katharine found herself thrown into a new job, that of newspaper publisher. But determined to save the family paper for her children, Katharine rose to the challenge of running the Post, attending meetings in every department, working endlessly to prove herself to her critics, and becoming the toast of Washington.

In 1971 ,Katharine ordered the Post to print a copy of the Pentagon Papers, the top-secret documents revealing the truth about the United States' involvement in the Vietnam War. What's more, her courageous decision and support for her journalists prepared the Post to break the most important political story in modem history: Watergate (水門事件), one of the greatest scandals(丑聞) in American political history. Katharine managed to keep control over the most chaotic of situations when it was reported ,all the time insisting the news stories be accurate and fair. Watergate made the Washington Post an internationally known Paper and Katharine was considered as the most powerful woman in America.
