Scientists have discovered how a hi-tech glass of milk is helping bones to mend, it has been reported.
Researchers from the University of Warwick in the UK explain that low-temperature bioglass is a reactive type of glass ceramic that has been investigated for use as an implant material to help repair and replace damaged bone.
However, they note that no-one has been able to understand how the process works as yet.
In news that may have implications for osteoarthritis treatment, physicist professor Mark Smith explains that researchers working at Imperial College in London, UK, discovered a new type of bioglass that seemed to work better than existing types, but they could not understand why.
He adds that the scientists used a strong magnetic field which allowed them to 'see' the bones and saw calcium enter the bioglass in the first hour after it was implanted.
"We looked at it through our nuclear-magnetic resonance machine and were amazed by what we saw," he explains.
The physicist concludes: "Fluid simulating patient's bodies rushed calcium out of the bioglass and then into the new bones. It seems perhaps a glass-of-milk-a-day really is what the doctor ordered."
