我以為壓力大也就是會脫發(fā)失眠而已，沒想到細胞的衰老速度還會加快六倍...想到這里我的壓力不禁又大了一點。

New research shows just how stressful starting a new career as a doctor can be: stressful enough to have your DNA age six times faster than it normally would.

一項新研究表明，開始醫(yī)生新職業(yè)的壓力有多大：壓力足以讓你的DNA衰老速度比正常情況快六倍。

? age：熟詞僻義 在這里是動詞“變老；老化”的意思，不是我們常用的“年齡”

Scientists studying cellular ageing through DNA telomeres (the 'tips' of our chromosomes), which shrink as we get older, found that this natural shrinkage was happening at an accelerated rate among new doctors – the equivalent of six years' worth of shortening in just 12 months.

科學(xué)家通過DNA端粒(染色體的“尖端”)研究細胞衰老，隨著年齡的增長，端粒會收縮。他們發(fā)現(xiàn)，新醫(yī)生體內(nèi)的這種自然收縮速度正在加快——這相當于在短短12個月內(nèi)縮短6年的時間。

? cellular ageing: 細胞老化。

? at an accelerated rate: 以加快的速率；也就是速度正在加快。

? the equivalent of ：相當于

It's the first large, longitudinal study to look at the link between chronic stress and cell ageing, and the team behind the research says it could have implications for those in any high-pressure situation, from trainee soldiers to new parents.

這是第一個大型的縱向研究，著眼于慢性壓力和細胞衰老之間的聯(lián)系，研究團隊表示，這可能會對任何高壓環(huán)境下的人產(chǎn)生影響，從新兵到新父母。

? chronic stress：慢性壓力。chronic: adj.? /?kr?n?k/? 慢性的; 長期的,我們生活當中常常聽到的“慢性病”中的“慢性”就是這個詞。

? 這里的cell ageing 同義替換上文的cellular ageing

? have implications for = Have impact on sth對...產(chǎn)生影響。

? trainee soldiers：新兵。? trainee：n. 接受工作培訓(xùn)的人；實習(xí)生

"Research has implicated telomeres as an indicator of ageing and disease risk, but these longitudinal findings advance the possibility that telomere length can serve as a biomarker that tracks effects of stress," says one of the team, neuroscientist and psychiatrist Srijan Sen from the University of Michigan (U-M).

“研究表明端粒是衰老和疾病風(fēng)險的一個指標，但這些縱向研究結(jié)果提出了端粒長度可以作為一種生物標志物來跟蹤壓力的影響的可能性，”研究小組成員之一、密歇根大學(xué)(University of Michigan)的神經(jīng)學(xué)家和精神病學(xué)家斯里揚·森(Srijan Sen)說。

? implicate: V.? /??mpl??ke?t/ 表明[暗示]

? Advance? 熟詞僻義 在這不再是我們熟悉的“進步”的意思，而是動詞“造成、促成”，舉個例子造成; 促成 eg:When not producing art of his own, Oliver was busy advancing the work of others. 沒有創(chuàng)作自己的藝術(shù)品時，奧利弗就在忙于促成他人的作品。

? Serve as: 充當； 擔(dān)任；起....的作用。

? Biomarker: 生物標志物。

"It will be important to study how telomere changes play out in larger groups of medical trainees and in other groups of people subjected to specific prolonged stresses."

“研究端粒變化如何在更大范圍的醫(yī)學(xué)培訓(xùn)生群體和其他長期承受特定壓力的人群中發(fā)揮作用，將是很重要的?！?/p>

? Play out: 發(fā)揮作用

? Subject: 熟詞僻義?！灿戎搁L期〕使遭受，使經(jīng)歷，使蒙受。subject sb/sth to sth ： Police subjected him to hours of questioning.警察對他進行了長時間的盤問。

? Prolong: V. /pr??l??/ 延長，拉長，拖長〔感覺或活動〕 同義詞：lengthen eg: There’s no point in prolonging the agony any longer.沒有必要再拖著不說，讓人等得這么著急。

The researchers took DNA samples from 250 new doctors at the start and end of their first intern year. These were compared to samples from 84 UM freshmen students. In addition, the team measured the participants' mental wellbeing and stress levels over time with the use of questionnaires throughout the year.

研究人員從250名新醫(yī)生身上提取了DNA樣本，這些醫(yī)生都是在他們第一個實習(xí)年度的開始和結(jié)束時進行的。這些數(shù)據(jù)與84名密歇根大學(xué)新生的樣本進行了比較。此外，研究小組還通過全年的問卷調(diào)查，測量了參與者的心理健康和壓力水平。

Besides "telomere attrition" being six times greater in the doctors, some other interesting findings came to light? for example, the longer hours the new doctors worked, the faster their telomeres shrank.

除了醫(yī)生的“端粒磨損”是常人的六倍之外，一些有趣的發(fā)現(xiàn)也浮出水面——例如，新醫(yī)生工作的時間越長，他們的端粒萎縮得越快。

? Come to light: 出現(xiàn)； 浮出水面。

? the longer ...the faster: 時間越長...越快... the+比較級..the+比較級。越怎么樣...越怎么樣。
