Peptides, Wnts, and Volume Rendering

It’s always interesting to see information on future developments that are underway (all from Spirit magazine):

1. Using a peptide to help you lose weight.  Based on research at Indiana University with mice this might be possible. 
2. Using “Wnts” to heal broken bones faster.  Based on work at Stanford University where the stem cells in the bone tissue are stimulated.
3. Using volume rendering (ala 3-D movies) to provide images of people innards to help with surgery and diagnosis.
4. Using probiotics in smoothies to administer vaccines.  Based on research being done at Northwestern University. 

Interesting.
