People at risk of heart attacks are often prescribed aspirin to thin the blood, but now scientists believe that MAGNETS could one day be used instead.
Scientists at Temple University in Michigan found that a device that uses a magnetic field to thin fuel, can have the same effect on human blood. Professor Rongjia Tao pioneered the use of electric or magnetic fields to decrease the viscosity of oil in engines in 2008. He realised that this could work on our own circulation system in a similar way.
Because red blood cells contain iron, Tao has been able to reduce a person's blood viscosity (resistance to flow) by 20-30 per cent by subjecting it to a magnetic field for about one minute. The field measured 1.3 Telsa which is about the same as an MRI machine. After testing numerous blood samples in a laboratory, Tao found that the magnetic field polarises the red blood cells causing them to link together in short chains, streamlining the movement of the blood.
