【导读】从古至今,长寿甚至是永生,一直都是不少人追求的终极目标。而近日科学家们发现,长生不老的秘诀或许能在一种“不会老”的动物身上找到……

中文 英文 双语

From the stories of ancient Greece to science fiction movies, immortality has long been something that humans have talked about.
从古希腊故事到科幻电影,永生一直以来都是人们谈论的话题。

We’re often told that the secret to a longer life is down to eating a healthy diet and taking regular exercise.
我们经常听说长寿的秘诀在于健康的饮食和有规律的锻炼。

Yet according to a Google-owned company, the answer could lie in an unusual-lookingrodent called the naked mole rat.
然而谷歌旗下的一家公司却认为,(长寿)的答案在一种长相奇特的啮齿类动物——裸鼢鼠的身上。

Calico, a company co-founded by Google in 2013, says it wants to figure out why our body ages, calling it the “most fundamental unsolved problem in biology” , by studying the strange creature, whose DNA shares an 85 percent similarity to humans’.
Calico是谷歌于2013年合作创立的一家公司。该公司表示,裸鼢鼠的DNA与人类有85%的相似性,他们希望通过研究这种奇特的生物,找出我们身体变老的原因,并称之为“生物学中最根本的未解之谜。”

Native to East Africa, the animal looks like a baby mouse, with pink, wrinkly skin and large teeth.
这种动物原产于东非,长得很像小老鼠,有着粉色褶皱皮肤以及巨大的牙齿。

It can survive for years in harsh conditions in underground tunnels, and lives for around 30 years, more than five times longer than mice.
它能在地下隧道的严酷环境中生存数年,寿命在30年左右,超出一般老鼠寿命的5倍。

The amazing animal’s body can even create oxygen “like a plant” if it’s placed in conditions without air, and is highly resistant to cancer.
如果这种奇妙的动物身处于没有空气的环境中,它的身体甚至还能“像植物一样”创造氧气,而且对癌症有很强的抵抗力。

So how will this help humans live longer?
所以这些特点要如何帮助人类变得更长寿呢?

According to a 2014 study by researchers at the American Friends of Tel Aviv University in New York, the naked mole rat’s body contains high levels of a protein which scientists believe is what keeps it from aging.
纽约的以色列特拉维夫大学美国之友的研究人员2014年发布的一份研究显示,裸鼢鼠的身体中含有一种高水平的蛋白质,科学家们认为这种蛋白质是裸鼢鼠永葆活力不变老的原因。

Unlike humans, as naked mole rats grow older, their bodies don’t grow weak and their brain functions don’t worsen, meaning that elderly naked mole rats are still as strong as younger ones.
和人类不同的是,随着裸鼢鼠变老,它们的身体不会变得虚弱,大脑功能也不会退化,这意味着年老的裸鼢鼠仍和和年轻的裸鼢鼠一样健壮。

“There’s still a lot we can learn from extremely long-lived animals,” Rochelle Buffenstein, a professor at the University of Texas, US, wrote in a study on naked mole rats.
“我们还有很多东西要向那些特别长寿的动物学习,”美国德克萨斯州大学教授译成中文在一份裸鼢鼠的研究报告中写道。

She added that studying the animal may allow us to “evaluate whether nature – through millions of years of evolutionary experimentation – has already evolved the best way to delay the aging process.”
她补充道,研究这种动物或许让我们能够“评估大自然是否在经过了数百万年的进化实验后,已经进化出了延缓衰老的最佳方式。”
