Nanomushroom via @MCHScience

This “nanomushroom” happened to grow among a field of nanowires. Researchers grow many types of nanostructures, some for their intrinsic properties, and others as tools. The Electron Transfer group at New Mexico State University grows their nanowires to help probe the electron transfer properties of organic molecules. The mushroom may not be quite what they were looking for, but it is a great example of the range of shapes nanostructures can come in.

The self-assembly(1, 2)and the evolution(3)of a molecular nanowheel

Or, in other words, the creation of life-like cells from metal: Leroy Cronin and his team have try to demonstrate that life could be born also from metal atoms.

There is every possibility that there are life forms out there which aren’t based on carbon, On Mercury, the materials are all different. There might be a creature made of inorganic elements.
