Scientists say they have made a leap in knowing why some people retain their youthful looks while others age badly。

科学家称他们已经在探究为什么有的人青春长驻而另一些人逐年老去这一问题上取得突破性进展。

They found the first part of human DNA - the genetic code - that seems to affect how old people look to others。 The mutations, reported in the journal Current Biology, were in the genetic instructions for protecting the body from UV radiation。 But these can also lead to red hair, and experts caution the findings may be confused by eye, skin or hair colour。

他们发现人类DNA——基因密码——的第一部分似乎会影响一个人在别人眼里看起来有多老。据《当代生物学》杂志报道,遗传指令会发生变化,保护身体免受紫外线辐射的伤害。但这些变化同时会导致头发变红,而且专家警告说研究结果会受到瞳色、肤色或发色的影响。

The study into “perceived age” was organised by the Erasmus University Medical Centre in the Netherlands and Unilever。 Images of the make-up free “naked-face” of 2,693 people were independently assessed to see what age people thought they looked。 This was compared with their true age。 The next stage of the research was to scour the 2,693 people‘s DNA to find any differences or mutations that were more common in those who looked younger than they really were。

荷兰伊拉斯姆斯医学中心和联合利华共同组织了本次针对“外 表年龄”的研究。试验中分别评估了2693位完全没有化妆的“裸脸”人员照片,看人们认为照片里的人有多大年龄,再将评估结果与他们的真实年龄进行比照。 试验的下一个步骤是检测这2693个人的DNA,探究那些看起来比实际年龄更显年轻的人有什么共同之处,找到他们的基因与别人相比有什么不同特点或变异之 处。
