- MIT probes secret to bone's strength
08-27-2007 · EurekAlert!
New research from MIT appearing in a recent issue of Nanotechnology reveals for the first time the role of bone's atomistic structure in a toughening mechanism that incorporates several previously proposed theories. This mechanism allows for the sacrifice of a small piece of the bone in order to save the whole, helps explain why bone tolerates small cracks, and seems to be adapted specifically to accommodate bone's need for continuous rebuilding from the inside out.

- Testosterone replacement therapy
08-08-2007 · EurekAlert!
Testosterone supplements have been used by aging men to improve their muscle mass, bone strength, libido and quality of life. The cardiovascular effects of chronic testosterone treatment in aging males are largely unknown, and the safety of testosterone replacement has not been evaluated. A team of researchers has been using an animal model to investigate potential links between testosterone supplements and cardiovascular and renal disease.
