Remote-controlled

When people are attempting to clean up oil spills at sea, one of the key things they need to know is the amount of oil that's been spilled. In order to make that process easier, scientists have developed an ROV that does the job by measuring the thickness of oil slicks from below the surface.

Researchers have hijacked sperm cells to create spermbots that can be remotely controlled through magnetic fields, to go to the desired location and do their job. The technology could offer a viable alternative to parents trying to have a child through in-vitro fertilization.

Researchers have been able to non-invasively control the walking paths of turtles.
