    The development of both the physical and aesthetic properties of materials used to be a collaboration between the arts and the sciences. The potential rewards of reviving such a vibrant culture are great, and would benefit both the creative arts and materials science.

    Large arrays of vertical laser sources need to emit a coherent output of light. This can be achieved through photonic crystals that mediate the interaction between the lasers in the array.

    Most of the outstanding properties of carbon nanotubes rely on them being almost atomically perfect, but the amount of imperfections, and the effect that they have on the tube properties, has, to date, been poorly understood. New work shows that even a very low concentration of missing atom-pairs in the nanotubes has a large effect on their electrical conductance.
