Scientists computationally design new metastable, ultra-light crystalline form of aluminum using density functional calculations with imposing periodic boundary conditions. If you drop an aluminum spoon in a sink full of water, the spoon will sink to the bottom. That’s because aluminum, in its conventional form, is denser than water says Utah State University chemist Alexander Boldyrev.

But if you restructure the common household metal at the molecular level, as Boldyrev and colleagues did using computational modeling, you could produce an ultra-light crystalline ...
