The contention of a major but controversial new theory to explain nanocrystal growth is that nanoparticles can act as “artificial atoms,” forming molecular-type building blocks that can assemble into complex structures. The conclusion is based on recent observations of growing nanorods made by Lawrence Berkeley National Laoratory researchers using transmission electron microscopy and advanced liquid cell handling techniques.

Tissue engineers can use mesenchymal stem cells derived from fat to make cartilage, bone, or more fat. The best cells to use are ones that are already likely to become the desired tissue. Brown University researchers have discovered that the mechanical properties of the stem cells can foretell what they will become, leading to a potential method of concentrating them for use in healing.
