Researchers at The University of Western Ontario's Schulich School of Medicine & Dentistry are using a section of 30,000 year old wooly mammoth tusk, unearthed in the Yukon, for modern medical research. Stephen Sims, a physiologist in the Musculoskeletal Health Research Group at Western, studies the cells that cause bone loss. He's hoping the ancient ivory will provide new insight which could lead to novel therapies for osteoporosis and other diseases of the bone.
