一个国际联合研究小组宣称已经开发出了一种精度很高的预测个人头发颜色的方法。新技术通过从现场留下的血液、精液、唾液或皮肤细胞中提取的DNA对嫌疑人头发的颜色作出判断,精度可达到90%。研究人员称,这将为法医学提供一项新的信息获取手段,有可能改变目前法医学在此方面的面貌。 An international joint research group claims to have developed a highly accurate method of predicting the color of an individual’s hair. The new technology is based on DNA extracted from blood, sperm, saliva or skin cells left on the scene to judge the color of the suspect’s hair, with a precision of up to 90%. The researchers say this will provide forensic science with a new means of obtaining information that may change the face of current forensic science in this area.
