Scientists have shown how controlled sperm cells inside tubes can be driven to target destinations using magnetic control. The significance of their investigation lies partly in what may be in store for in vitro fertilization. ...
Tiny hair-like structures (cilia) are found on the surface of most cells. Cilia are responsible for the locomotion of cells (e.g. sperm cells), they process external signals and coordinate the correct arrangement of the inner ...
