Graphene Spun into Meter-Long Fibers - Scientific American
So graphene oxide liquid crystals were dried out to make meters long (but imperfect) fibers which are weaker than normal carbon fiber, but have great conductivity. Has this been commercialized into low weight electrical wire yet?

So there is apparently a cockroach that births live young, and lactates to feed them. The milk they produce has a special multilayered milk protein crystal structure that acts as a time release complete food as it's processed, with integrated proteins/lipids/sugars. If this can can be reasonably synthesized, it' s a superfood (crystals have 3 times the caloric content of buffalo milk)

High Power Explosive with Good Sensitivity: A 2:1 Cocrystal of CL-20:HMX - Crystal Growth & Design (ACS Publications)
CL-20 is a the most powerful modern explosive known, but is as unstable as PETN, making it unsuitable as is ,due to impacts causing sudden detonation. But fixing it in a cocrystal with HMX makes a hybrid that has 20% more power over pure HMX, which is the more common military explosive, while being about as stable as regular HMX.

NASA - OCCAMS: Optically Controlled and Corrected Active Meta-material Space Structures
Wow, using photonic muscles embedded in a deployable thin film mirror, using a raster scanning laser to tweak the mirror as an active optical correction primary aperture mirror by using the muscles to deform the mirror. But, the concept suspiciously looks similar to a stealth radar deflection cone for spysats patented by Teledyne Ryan and allegedly used on Misty 1/2 and NROL-15.

Nanoscale Research Letters | Full text | Tailoring photonic metamaterial resonances for thermal radiation
This seems to use the same kind of tricks as those luminescent solar concentrator plates, that internally reflect captured light and convert the frequency internally to retransmit to edge PV modules. Just shifting down to IR. The interesting bit is the prevention of reradiation through the top surface, which provides the potential for solar thermal power generation without concentrating mirrors using not well aligned surfaces of panels manufactured using chip fabrication techniques.
