Magnetic needles turn somersaults

Scientists at the Max Planck Institute of Metals Research in Stuttgart have discovered a new mechanism with which it is possible to use weak magnetic fields to reverse tiny magnetic structures, called vortex cores, quickly and with no losses. Up until now, very strong magnetic fields have been necessary to accomplish this, requiring highly complex technology. The new method might open up new possibilities for magnetic data storage.

1. New property found in ancient mineral lodestone
   12-17-2007 · EurekAlert!
   Using the latest nanofabrication methods, a team of Rice University physicists has discovered a surprising new electronic property in one of the earliest-known and most-studied magnetic minerals on Earth -- lodestone. Also known as magnetite, lodestone was used to make compass needles as early as 900 years ago. In new research in Nature Materials, the researchers describe how super-cooled magnetite reverted from an insulator to a conductor when the voltage was altered in their experiment.

2. Nanoparticles that cancer cells can't resist
   07-11-2007 · EurekAlert!
   A technique that turns cancer cells into miniature magnets could make biopsies more efficient. Researchers in Alburquerque have come up with the idea of using magnetic nanoparticles. The particles are encased in a biocompatible material and then coated with antibodies that bind to chemicals found only in cancer cells. When injected into the body, the particles stick to cancer cells, turning them into miniature magnets. These cells can then be drawn towards magnets encased in the end of a biopsy needle.
