A research group at Lawrence Livermore National Laboratory has produced ultrastiff ultralowdensity metamaterials by 3D printing of microarchitected microlattices. This is very cool – they do additive 3D printing using microstereolithography with nanocoating and postprocessing and can make self-similar lattices with densities varying by several orders of magnitude in bulk density but near constant stiffness.…

Senior Review is out: summary – Swift #1, then NuStar. K2 gets partial funding. Spitzer is terminated. Panel recommends not cutting off the bottom but balancing fields. NASA Response to the 2014 Senior Review for Astrophysics Operating Missions – Final Version for Release (5.16.14) – this is an edited update of the NASA response that…
