与臭氧层类似，磁层对地球生物至关重要，绝大多数来自太阳的有害射线和热等离子体都被地球磁层折射回太空，从而使我们免受伤害。
Like the ozone layer, the magnetosphere is important to life on Earth because it protects us from most of the harmful radiation and hot plasma from the Sun, deflecting it into space.
这个团队不是研究X光射线如何被不同的材料吸收，反而是关注X光射线如何转向或者当x光射线穿过不同物体时如何折射。
Instead of relying on how X-rays are absorbed by different materials, they have instead focused on how they are diverted or refracted as they pass through different substances.
研究人员称，有一种新材料也许能提供一种可以让物体隐形的思路，因为这种材料可以改变光线和其它形状的辐射线在物体上的折射方向。
New materials that can change the way light and other forms of radiation bend around an object may provide a way to make objects invisible, researchers said.
