A “magnetic hose” consisting of concentric tubes of superconducting and ferromagnetic materials can transmit magnetic fields. A tube consisting of 20 concentric rings that is about ten times longer ...

Researchers have demonstrated that the spiral geometry of tiny, twisted magnetic tubes can be leveraged to transmit data ...

Engineers and scientists have developed proof of concept for a robot that can reach some of the smallest bronchial tubes in the lungs -- to take tissue samples or deliver cancer therapy. Known as a ...

Hijacking sperm cells to create little robots might seem far out, but that's exactly what researchers from the Dresden Institute for Integrative Nanosciences have done. Their "spermbots" consist of ...
