Science on a roll in 2007

Magnetic fields and hot iron may not sound like the latest tools in cancer treatment, but scientists in Germany would beg to differ. When iron nanoparticles are injected near the site of a tumour, they seek out and attach themselves to cancerous cells. Exposing the patient to a changing magnetic field causes these nanoparticles to heat up, and as tumour cells are more sensitive to heat than healthy cells, they're destroyed by the hot iron nanoparticles. Still in trials at the moment, this may enter healthcare in the new year.
