新闻报道2
Mobile phones have changed the way we live, how we read, work, communicate, and shop.
手机已经改变了我们的生活方式，改变了我们阅读、工作、交流和购物的方式。
But we already know this.
但是这一点我们已经有所了解了。
What we have not yet understood is the way the tiny machines in front of us are changing our skeletons, possibly altering not just the way we behave but even the very shape of our bodies.
我们还不了解的是，我们面前的微型机器正在改变我们的骨骼，可能不仅改变我们的行为方式，甚至改变我们身体的形状。
New scientific research at the University of the Sunshine Coast in Queensland, Australia, suggests that young people are developing extra pieces of bone at the backs of their heads.
澳大利亚昆士兰阳光海岸大学的一项新的科学研究表明，年轻人的后脑勺正在长出额外的骨头。
These pieces of bone are caused by the way people bend their heads when they use the phone.
这些骨头碎片是由于人们使用电话时低头的方式造成的。
This shifts weight onto the muscles at the back of the head and causes the bone to grow in a way that is not normal.
这一动作会将重量转移到头部后部的肌肉上，导致骨骼以一种不正常的方式生长。
This process can be compared to the way the skin hardens in response to constant rubbing or pressure.
这个过程可以与皮肤在不断摩擦或压力下变硬的方式相提并论。
The result is a piece of bone like a horn that sticks out from the head by the neck.
结果是一块像角一样的骨头从脖子处伸出来。
