A new hypothetical material offers the tantalizing possibility of a signal path smaller than the nanowires for advanced electronics.

Yes, theoretical materials. It must be the weekend. 

Rice University theoretical physicist Boris Yakobson and postdoctoral fellow Xiaolong Zou were investigating the atomic-scale properties of two-dimensional materials – we all have those laying around the house to build Christmas gifts – when they concluded that a particular formation, a grain boundary in metal disulfides, will create a metallic, and therefore conducting, path only a fraction of a nanometer wide. 

That’s basically the width of a chain of atoms.
