For one, there were signs of radiation damage in Scott's chromosomes.

首先，斯科特的染色体中有辐射损伤的痕迹。

The Sun makes life on Earth possible, but too much exposure to its UV radiation damages plant and animal DNA.

太阳让地球上的生物能够存活，但过量的紫外线辐射会损害植物和动物的 DNA。

In particular, the researchers discovered the gene for a protein apparently unique to water bears that shields their DNA from radiation damage.

特别是，研究人员发现水熊有一种可以保护其DNA免受辐射伤害的独特蛋白质。

The temperature increase in the stratosphere might also cause major losses in the ozone layer -- which would cause more exposure to ultraviolet radiation, damaging our health and our agricultural crops.

平流层温度升高还可能导致臭氧层严重损失， 从而导致更多的紫外线辐射，损害我们的健康和农作物。

In a paper published in Nature this week, Japanese researchers found some of the genes that make tardigrades so tough – including a protein that can also protect human DNA from radiation damage.

在本周发表在《自然》杂志上的一篇论文中，日本研究人员发现了一些使水熊虫如此坚韧的基因——包括一种也可以保护人类 DNA 免受辐射损伤的蛋白质。
