PREVIOUSLY touted as a possible treatment for migraine, stroke and even coma, transcranial magnetic stimulation (TMS) has been given its first official stamp of approval by the US Food and Drug Administration - as a treatment for depression in people who fail to respond to antidepressant drugs.
In TMS, an electromagnetic coil is held over the patient's head to induce a weak electric current in their brain tissue. Several large trials have suggested it can be useful in treating depression, as the coil's rapidly changing magnetic fields excite cells in the areas of the brain involved in mood regulation. Neuronetics of Malvern, Pennsylvania, says that in the latest trials it submitted to the FDA more than half of depressed people treated showed.... Click Here to Read More...

AS THE transistors etched into computer chips approach their limits of miniaturisation over the coming years, they could be replaced by devices that use magnetism instead of electricity to store and manipulate digital data.
Magnetic storage devices known as magnetic random access memory (MRAM) already exist. But now Alexandra Imre and colleagues in the nanoengineering department at the University of Notre Dame in Indiana have shown that magnets around 0.1 micrometres across can be arranged to produce the basic building blocks of a processor chip...

Could magnets make the mind grow stronger? In mice at least, stimulating the brain with a magnetic coil appears to promote the growth of new neurons in areas associated with learning and memory. If the effect is confirmed in humans, it might open up new ways of treating age-related memory decline and diseases like Alzheimer's....Click Here to Read More...

Tiny particles of iron may help doctors deliver targeted cancer drugs using the pull of a magnet, says a UK researcher. And such treatments could potentially improve the effectiveness of tumour-killing drugs while reducing the painful side effects associated with traditional treatments.
"It's a new way of driving drugs around the body. Drug trafficking, if you will," says Andrew Harrison, a materials chemist at the University of Edinburgh, who is developing the technique.... Click Here to read more

Superconducting magnets could help a fleet of spacecraft fly in precise formation without using up limited fuel reserves, two groups of researchers say. But others foresee problems with the technology....Click Here to Read about the Future of Space Travel and the wonders of the role MAGNETS PLAY

"Not only does God play dice with the Universe,
he sometimes casts them where they can't be seen."
Around the clock, the sky is raining silver and gold - not to mention copper, zinc, hydrogen, carbon, oxygen, and other elements. These atomic particles travel near the speed of light toward Earth, steadily drenching the planet with a teeming downpour. If it weren't for the protective umbrellas of our atmosphere and magnetosphere, we'd be soaked...Click Here To Read More...
