【在生活中學習語言】《中英對照讀新聞》Scientists find way to calculate people’s real age 科學家找到推算人類真實年齡的方法

◎鄭寺音

Researchers studying genes believe they can now detect exact "physical age" by looking at a number of clues - or biomarkers - in DNA.

基因研究者認為，現在他們可以藉著研究DNA裡的數種線索－或稱生物標誌，偵測出確切的「身體年齡」。

They believe that the tests will be the first time doctors can accurately predict someone’s physiological age objectively without resorting to asking them how they feel or looking at their appearance.

他們相信，這項測試，是醫師首度不用詢問某人身體如何或是觀察他們的外貌，就能客觀正確地預測他們的生理年齡。

The breakthrough could solve the mystery of why some 70-year-olds function at the level of those in their 50s, while others become frail sooner than would be expected.

這項突破性發展或許可以解釋，為什麼有些70歲的人身體機能像是50幾歲，有些人卻比實際年齡更快衰老的原因。

The researchers made the breakthrough by isolating the "biomarkers" of ageing in tiny worms which behave similarly to humans.

研究人員是藉著分離出小蟲子體內、表現類似人類的老化「生物標誌」，來達成這項突破性發展。

Like humans, some of the worms remain sprightly much longer than their similarly-aged brethren.

這些蟲子有些就像人類一樣，比類似年齡的同胞活得還要生氣蓬勃。

By genetically profiling 104 different worms - at various ages - the researchers isolated a suite of genes and biomarkers that are actively involved in the ageing process.

研究人員藉著描繪104種不同蟲子在不同年齡的基因，分離出一套會在老化過程中活躍的基因與生物標誌。

新聞辭典
