They allow them to change shape, to move around, to adhere to surfaces and also to gobble up bacteria.

它们让细胞改变形状，四处移动，附着于表面，以及吞噬细菌。

As the frequency of the rubbing reaches that at which the bowl naturally vibrates, the bowl's edge begins rhythmically to change shape, from one slightly oval shape into another.

当摩擦的频率达到了碗自身的振动频率时，碗的边缘便会有节奏地改变形状，从一个略微的椭圆形变成另一个略微的椭圆形。

And this is the ability to program physical and biological materials to change shape, change properties and even compute outside of silicon-based matter.

这就是通过编程使物理和生物材料改变形状、改变属性的能力，它的应用范围甚至超过了硅基物质。
