当剑桥大学的科学家首次听到一种病毒在抗体中挣扎时,这种声音应该引起烦躁不安的病人发出相同抚慰的叹息。他们一直在测试一种新设备,它可以听见血样中存在的病毒。对于多数有时需要等待几天才能得到化验结果的病人来说,这项发明意味着能立即检测艾滋病病毒、肝炎和数10种其它的病原体,包括炭疽和天花。剑桥 When the scientists at Cambridge University first heard of a virus struggling with antibodies, the sound should cause the irritated patient to make the same sigh of consolation.
