That's Mr. BoneHead to You!

Gerard Karsenty has been studying osteocalcin for decades now and recently published a paper showing how bone plays a direct role in memory and mood. It seems that while being a protein, osteocalcin acts as a hormone and a "messenger, sent by bone to regulate crucial processes all over the body."

The question I'm  left with: Is there a connection between osteocalcin and glia? Send your theories here. And do some resistance exercises.
