Astrophysicists And Cell Biologists Team Up To Develop A New Technique To Grow New Bone

"Nanokicking" Stem Cells Offers Cheaper and Easier Way To Grow Bone. Medical News Today.  April 5, 2013.

The "nanokicking" is derived  from laser interferometry, an astrophysical technique.  It replicates a vibration that occurs in the membranes of bone cells when they stick together to form new bone naturally.  Nanokicking causes mesenchymal stem cells to differentiate into bone cells.  Next the researchers will work with rehabilitation engineers to help patients.
