Printing artificial bone - MIT News Office
Based on the internal hierarchical structure of bone/nacre, the research suggests a internal diamond scaling pattern may improve over classical biomimicry for strength and deformation resistance. Which may have defense applications in body armor.

Bioinspired fibers change color when stretched — Harvard School of Engineering and Applied Sciences
Interesting photonic fiber research, which resembles dichroic materials, but because it is stretchable, allows active changing of the color by adjusting the bandgap. Possible uses in smart cloth showing deformation damage, or as a possible active camouflage textile system.

BNL Newsroom | Breakthrough Iron-based Superconductors Set New Performance Records
New high current/high magnetic field/high temperature superconductor that is iron based that beats the pants off of existing iron and cuperate superconductors. Demonstrated 1MA/cm2 critical current, 200KA/cm2 at 30T at 43K (not quite LN2 temps but close), and they think they can up the temperature by further tweaking the layering.
