This is Scientific American — 60-Second Science. I'm Christopher Intagliata.
Here's one of the stranger celebrity sightings out there: Researchers have confirmed that sheep can recognize the actors Emma Watson and Jake Gyllenhaal.
"Yeah I think it's very cool." Jennifer Morton is a neurobiologist at the University of Cambridge. "The reason we chose celebrities is we were sure they'd never met these people."
The experiment worked like this. First, Morton's team trained eight sheep to recognize the famous faces. And the sheep correctly chose the celeb's face over a stranger's 80 percent of the time.
Next they presented faces at a slight angle. The sheep got only two-thirds of those right. But that's far on par with how human performance dips for the same task.

Proving that sheep have advanced facial recognition skills, the scientists say...comparable to humans or our primate cousins. The study is in the journal Royal Society Open Science.
If you're wondering, "Why sheep?"
"Sheep chose me rather than the other way around." There's a good model of Huntington's disease in sheep. So Morton says studying cognitive tasks like facial recognition in sheep—and the decline in those abilities in Huntington's sheep—might offer insights into the human condition, too.

有一个奇怪的名人行踪消息:研究人员证实,绵羊能认出演员艾玛·沃特森和杰克·吉伦哈尔!u.fhG8zfvS[HZ)&u
“我觉得这非常酷oc[g5DPg=uLSgYKSIt。”剑桥大学的神经生物学家詹妮弗·莫顿说到a2Zc7Rdv!01-。“我们选择名人的原因是,我们确定绵羊从来没有见过这些人vAvY=IwClIbv_&u*C0。”
实验过程如下mzkS[1z8UsaY。首先,莫顿团队训练8名绵羊识别名人面孔5o8)nII2GJc^kMCxN。绵羊从陌生人中选出名人面孔的准确率为80%bYjzB+GEI6a*
接下来,研究人员给绵羊看的是有点儿角度的名人面部图片GxYjhFAw6p]w。这次的正确率仅有三分之二#Lu.m3D|xXDFJIxa2S=。但是这与人类的正确率不相上下5d%34bN,~Cz0al+
科学家表示,这证明绵羊拥有先进的面部识别技能,可与人类或灵长类动物相媲美t2S3[A38.dc~Q1。这项研究结果发表在《英国皇家学会·开放科学》期刊上;ayMjww6qELPX)5gGmm(
如果你想知道,“为什么用绵羊进行实验?”
“其实是绵羊选择了我,而不是我选择了绵羊T*Pmlt.FOjJDoXay8。”绵羊可能会患上亨廷顿舞蹈症|ZW_7LUhNG=i1v*50*oJ。所以,莫顿表示,研究绵羊的面部识别技能以及患有亨廷顿氏舞蹈症的绵羊识别能力下降等识别任务,可能会帮助我们理解人类的类似疾病IPKcW@X~#TmZ0aNXhk=#
