两名美国人和一名丹麦人共享诺贝尔化学奖
瑞典皇家科学院周三（10月5日）宣布，三位科学家因“点击化学（click chemistry）和生物正交化学（bioorthogonal chemistry）的研发”成就而获得诺贝尔化学奖。
该奖项及其90万美元的奖金由美国人卡罗琳·贝托齐（Carolyn Bertozzi）和巴里·夏普莱斯（Barry Sharpless）以及丹麦人莫滕·梅尔达尔（Morten Meldal）三人平均分享。
对于夏普莱斯来说，这是他在2001年获得诺贝尔化学奖后，第二次获得诺贝尔化学奖。
瑞典皇家科学院表示，梅尔达尔和夏普莱斯各自独立地提出了一种化学反应，该反应现在被广泛用于开发药物和材料，以及用于绘制DNA图谱。
瑞典皇家科学院还说，贝托齐则是通过在生物内部起作用的反应，进一步地发展了该领域，其应用包括探索细胞和追踪生物过程。
诺贝尔医学奖和物理学奖已经本周早些时候颁发，诺贝尔文学奖和诺贝尔和平奖将于周四和周五宣布。

Three Share Nobel Prize in Chemistry
The Royal Swedish Academy of Sciences announced Wednesday three scientists won the Nobel Prize in chemistry for “the development of click chemistry and bioorthogonal chemistry.”
The prize and its $900,000 award went equally to Carolyn Bertozzi and Barry Sharpless of the United States and Morten Meldal of Denmark.
For Sharpless, it is his second Nobel Prize in chemistry after being awarded the honor in 2001.
The academy said Meldal and Sharpless each independently presented a chemical reaction that is now used widely to develop pharmaceuticals and materials, and for mapping DNA.
Bertozzi developed the field further with reactions that function inside living things, the academy said, with applications that include exploring cells and tracking biological processes.
The Nobel Prize for medicine and for physics were awarded earlier this week, with the literature prize and the Nobel Peace Prize due to be announced Thursday and Friday.
