In other news of great import:
"The ground state of the triangular boron lattice is electronically degenerate. The degeneracy is lifted, and the energy thus lowered, when the sheet buckles slightly. Before Tang and Ismail-Beigi's work, the buckled triangular lattice was the 2D boron-sheet structure with the lowest known energy. Researchers figured that boron nanotubes would be made of rolled-up pieces of the buckled triangular lattice, with the buckles running either parallel to the length of the tube or in helices around it. Calculations showed such structures to be stable."
