    Healing Wounds: Interactive dressing speeds the process

    A new, easily prepared hydrogel material promotes more rapid wound healing in laboratory animals than do conventional dressings.

  5. Materials Science

    Molecular template makes nanoscale helix

    Using ribbons made of organic molecules as minuscule templates, researchers have coaxed a semiconductor material into tiny helical coils.
