A strange-looking little device may be able to stop a migraine in its tracks. That's what results of new research says. Dr. Jon LaPook reports.
... (AP) -- The government has approved the first noninvasive brain stimulator to treat depression - a device that beams magnetic pulses through the skull. If it sounds like science-fiction, well, those ...
... worked their way south. Using a highly sensitive magnetic device called a SQUID (Superconducting Quantum ... s magnetic field just like a compass. As the magma cools and becomes solid rock, the "compass" ...
... version of the giant magnetoresistance (GMR) effect, which uses such layered structures for extremely sensitive magnetic field detectors. Arrays of nanoscale sandwiches of a similar type might be used ...
... new generation of computers and optical telecommunications networks. Using light rather than electronic or magnetic devices to store and move data is quicker, more energy efficient and cost-effective ...
Now a doctor may one day be able to manually control the location of this camera with a magnetic device the size of a chocolate bar.
... of the LCN, said: "This result represents a major advance in our understanding of this fundamental physical phenomenon and could have important consequences for future nanoscale magnetic devices."
... published in Physical Review Letters, the new research holds up a magnifying glass to how tiny magnetic devices behave. Using a special electron microscope that can 'see' magnetism, scientists imaged ...
... and even inserting impurities can determine whether a switch is more or less likely to be triggered and propagate, potentially adding a new dimension of control to the design of magnetic devices.
... light are extracted from this electron beam through the use of either bending, wiggler or undulator magnetic devices. These light beams are a hundred million times brighter than those from the best x ...
