Overly-viscous blood can damage blood vessels and lead to heart attacks. Therefore, people who are at risk of heart attacks take medications such as Aspirin, in order to thin their blood. Such drugs can have unpleasant side effects, however, and can only be taken a certain number of times per day. Prof. Rongjia Tao, a physicist from Philadelphia's Temple University, now thinks he might have come up with a better way of thinning human blood - he subjects it to magnetic fields.
Tao had previously researched the use of magnetism for decreasing the viscosity of oil in engines and pipelines. Because blood contains iron, it turns out that it, too, becomes more fluid when magnetized.
In lab tests, Tao and Temple collaborator Ke "Colin" Huang subjected human blood samples to a magnetic field of 1.3 Telsa (roughly equivalent to an MRI) for approximately one minute. This polarized the red blood cells, which caused them to link together into short chains. These chains, because they are larger than single cells, tend to flow down the middle of blood vessels, instead of creating friction by moving against the inner walls. All told, he was able to decrease the viscosity of the samples by 20 to 30 percent.
The blood did return to its original viscosity once the magnetic field was removed, although it took several hours to do so. It is apparently safe to repeat the treatment over and over, however, as the function of the red blood cells does not appear to be affected.
"By selecting a suitable magnetic field strength and pulse duration, we will be able to control the size of the aggregated red-cell chains, hence to control the blood's viscosity," said Tao. "This method of magneto-rheology provides an effective way to control the blood viscosity within a selected range."
More work is required, although Tao hopes to ultimately make the treatment available as a preventative therapy.
The research is being published in the journal Physical Review E.
Centuries ago, such people with the real answers to our cures of illness were burned at the stake. So, basically we are still 400 years behind where man-kind should be in the fight for a healthy life.
There are many companies already pedalling magnets and the majority work.
However there is only one company in this world that produces a magnet which \'mimics\' that of the \'Tens\" machine and probably the MRI magnet also.
It\'s affordable and guaranteed. Oh, the company is from Saltash, England.
Very seldom we come across BRAVE enough scientist that undertake this kind of research so I must congratulate him but to claim that it is a new discovery is only a new discovery for the small select group of his peers whom seem to believe that they can dictate to the rest of us what works and what doesn\'t.
The techology required to prove these theories, cost millions and millions of dollars and so they will always be theories and unscientifically proven and rubbished as snake oil, yet you ask anyone that wears one (a wrist magnet) whether it works. The answer will always be an absolute, \"YES!\"
Of course the easiest way to reduce heart attacks is to eat proper nutritious food but of course we all know that. So what\'s the problem?

Ken: -THE- technological breakthrough that has literally taken us from the dark ages, where even in peace life expectancy was about 30 years, to the modern world, where people regularly live into their hundreds, is the use of evidence rather than belief and tradition to test claims. As such, I think it\'s pretty reasonable to ask that people who, say, claim that magnets reduce pain, provide evidence supporting this claim. Scattered individual testimony doesn\'t really mean much when people can\'t tell whether they are wearing a magnet or not when you do a broad based study. That doesn\'t mean people should never go back and revisit the idea, but I for one would rather devote my time, money, and education to finding things that cause real improvements in the world, not silly stories from the gullible. If you think I\'m wrong then maybe we can shake a guinea pig to death to settle it, or you can stick pins in a doll that looks like me until I relent. I\'ll even send you some fingernail clippings if you need them.
People shouldn\'t get murdered for being silly, but this world doesn\'t have infinite resources and we have more important things to do than to chase solutions that have already been shown not to work, at least until someone comes up with GOOD evidence (and maybe some reasoning) that gives society a reason to revisit old ideas.
Perhaps that company in Saltash should start producing \'Ironman\' magnetic bling. Can\'t hurt anyone, unless they already have a pacemaker.
Could this be an Iphone app? Create a program to set the vibrator in a low oscilliting patern so that the electro magnets keep up a constant low energy magnetic field????
Think I\'ll go and sew some power magnets in my pockets meantime.
:-P
