MIT reported yesterday that their researchers have figured out the secret to bone strength and resiliency.
You’d think bones would be pretty boring when compared to more hipster organs like, say, the heart, lungs or eye. But turns out, bones are pretty remarkable pieces of engineering too.
Bone is rigid and flexible at the same time. And this has stumped scientists for decades.
The MIT team says that they’ve finally solved this mystery.
Turns out, bones are able to be both rigid and flexible by containing a perfect mixture of soft collagen and a hard, brittle mineral called apatite.
They say, “Neither material, on its own, could provide adequate structural support for the body.” But mix the perfect balance together and viola! You’ve got bone!
Restated in Geek Speak, bones contain hydroxyapatite grains which are “tiny, thin platelets just a few nanometers (billionths of a meter) across, and are deeply embedded in the collagen matrix. The two constituents are bound together by electrostatic interactions, which allows them to slip somewhat against each other without breaking.”
We agree with the MIT scientists… that’s remarkable!

Those of us who believe in an intelligent designer aren’t surprised to find such level of complexity, even in an organ like “simple” bone.
The human body is a remarkable piece of engineering, indeed. And everywhere you look, there is complexity waiting to be discovered.
