Judges in the United States Supreme Court have been debating tough legal and scientific questions on whether human genes should continue to be patented. Their decision which's expected in the summer could have enormous implications for research. The nine justices are looking at the right of one company Myriad Genetics to hold the patent on a genetic test for breast and ovarian cancer. Opponents say these patents prevent research by other companies and denied patients' access to the test which cost more than $3000. _____________________闭路电视画面显示,一名男子牵着他五岁儿子的手向路人求救,旁边是他妻子和幼女的尸体. 美国最高法院的法官们就是否继续授予人类基因专利权这一严肃的法律和科学问题展开辩论.他们的决定有望在今年夏天做出,这一决定可能对科学研究有重大意义.九名法官正在审查麦丽亚德基因公司进行乳腺癌和卵巢癌基因测试的权利.反对者则表示,这些专利阻碍了其它公司的研究,而高达3000多美元的测试成本将许多病人拒之门外.
