Spontaneous molecular oscillations are ubiquitous in biology. But to our knowledge, periodic cell migratory patterns have not been observed. Here we report the highly regular, periodic migration of ...

Any motion which repeats itself at regular intervals of time is known as periodic motion. If a body moves back and forth repeatedly about its mean position then it is said to be in oscillatory motion.

Customization of rotary and linear motion systems improves performance, reduces costs and simplifies complex applications in manufacturing and medical devices. Advances in smart, compact and ...
