摘要
科学家已经绘制了长寿动物北极露脊鲸的基因密码图，各国研究者通过共同努力揭示了北极露脊鲸基因非同寻常的特征，这些特征很可能帮助该物种避免与老龄相关的癌症和其他疾病。
Scientists have mapped the genetic code of this long-lived whale species. The international effort found unusual features in the Arctic whale＇s genes. Those features likely protect the species against cancer and other problems related to old age. The researchers hope their findings will one day translate into ways to help people too.
