国际著名生物学家、美国康奈尔大学教授、中国工程院外籍院士吴瑞先生，因心脏遽停 （cardiac arrest），于2008年2月11日在美国去世，享年七十九岁。
惊闻吴瑞先生去世, 去年7月还与他老人家在北京会议上见面交谈,他还为我们论坛作了题词. 给我们许多谆谆教诲, 这么快就走了?
It is with profound sadness and sorrow that I announce the untimely death of Dr. Ray Wu, an accomplished scientist and a passionate advocate for biological research in China. Dr. Ray Wu passed away on Sunday, February 10th, at the age of 79. His death is a tremendous loss to the life science community.
Dr. Ray Wu left behind a rich scientific legacy. Among many major accomplishments, Dr. Wu was a pioneer in DNA sequencing and developed the first method for determining nucleotide sequences of DNA in 1970. His method resulted in determination of the complete sequence of the two cohesive ends of lambda phage DNA in 1971. His method was later adopted by Sanger in the development of an efficient strategy for sequencing DNA. Dr. Wu later shifted his research focus to transgenic rice production because he realized during his visits to China in the 1980s that food shortage would become a major problem in China.
For the last 27 years, Dr. Ray Wu played an important role in promoting biological research in China. He is best known for instigating the CUSBEA (China-United States Biochemistry and Molecular Biology Examination and Administration) Program, which brought a total of 425 Chinese students from mainland China to the United States for graduate education between 1982 and 1989. Many of these students have gone on to become leaders in their respective research areas. The CUSBEA Program and its stunning success have had a lasting impact on the research community in the United States and in China.
The Chinese Biological Investigators Society will sponsor a memorial symposium in memory of Dr. Ray Wu. Details of the symposium will be announced at a later time.

A native of Beijing and a naturalized citizen of the United States, Wu earned his B.S. in chemistry in 1950 at University of Alabama and his Ph.D. in biochemistry in 1955 at the University of Pennsylvania. Before joining Cornell's Section of Biochemistry and Molecular Biology in 1966, Wu was a biochemist in the Public Health Research Institute of the city of New York.
He also has taught or conducted research at Stanford University, the MRC Laboratory in Cambridge, England, and Massachusetts Institute of Technology. He serves as an adjunct professor at Beijing University and is an honorary research scientist at 10 other institutes in China.
“The current focus of research in my laboratory is on regenerating transgenic rice plants transformed with agronomically useful genes. We have succeeded in transforming intact rice cells using high-velocity microprojectiles, as well as the Agrobacterium-based method, which has resulted in the regeneration of many fertile transgenic rice plants. Genes coding for the following proteins have been used to transform rice cells: protease inhibitors for producing insect-resistant plants, LEA3, LEA2, pyrroline-5 carboxylate synthetase, arginine carboxylase, and trehalose-6-P synthase and phosphatase for producing transgenic plants that are tolerant to drought, high levels of salt and low temperature. Other agronomically useful genes will be added to the list in the future…”
