MRI machines rely on massive superconducting magnets and complex software to produce detailed images of our organs and ...

Researchers have developed a tiny, flexible robot that could crawl through earthquake rubble to locate survivors or travel inside the human body to deliver medicine.

A collaborative study led by Professor Vittoria Raffa at the University of Pisa and Assistant Professor Fabian Raudzus ...

Accompanying those electrical signals are tiny magnetic fields that have only recently been tapped for information into how the human body works.

A gearbox driven by an external magnetic field can power tiny but powerful robots that crawl like a caterpillar or jump almost 40 times their own height, despite having no batteries or motors on ...

New research using magnetic fields shows potential for manipulating brain function, offering hope for future treatments of neurological disorders.

These micro-robots are a fraction of the width of human hair and have been successfully inserted into animal sinuses in pre-clinical trials. Once inside, the robots are guided by a magnetic field to ...

During a brief but dramatic chapter in Earth's history about 41,000 years ago, the planet’s magnetic field nearly collapsed. What followed was a cascade of environmental and biological changes ...

One big challenge, he says, is precisely controlling magnetic forces inside the human body that are generated from an external device.

Magnetic resonance technology is a common technique used for chemical analysis of compounds, however, traditional resonance technologies operate at high magnetic fields and they're very expensive.
