Phys. Rev. Lett. 117, 175901 (2016) - Lightweight Mechanical Metamaterials with ...
Using a cubic octet truss with internal members made of different materials, the internal expansion causes macro compression of the unit cell, shrinking things overall, achieving a negative thermal expansion coefficient metamaterial, of sorts.

Large isotropic negative thermal expansion above a structural quantum phase transition
Weird crystal that shrinks when it gets warmer. Trnasparent and doesn't seem to crack either, has other properties similar to electronics semiconductors.

Japan’s Workers: Please Don’t Send Me Abroad. Ever. - Japan Real Time - WSJ
So I've been hunting for this survey info ever since I half forgotten it. This is bad, in the sense that there are long term implications. A relatively self sustaining country, in terms of resources and exports, can afford to become someward inward looking and isolationist. Japan does not fall into that category. So, the youth, becoming more "me" focused and domestic looking, whle in and of itself is not necessarily a bad thing, for the country overall, Japan is screwed, baring a radical increase in technology that can not be replicated (unlikely), a radical increase in knowledge workers (which requires a global mindset, which this survey shows as lacking), or political changes that make it a corporate safe haven (no way that's happening), so it looks bad. Japan may simply be leading the way for first world countries to have their peak golden years, then settle into a comfortable moribund of suck, assuming what we are seeing is not the first world equivilent of the end of roman empire.
