text: Solitons may occur in proteins and DNA.  Solitons are related to the low-frequency collective motion in proteins and DNA.
  A recently developed model in neuroscience proposes that signals, in the form of density waves, are conducted within neurons in the form of solitons. Solitons can be described as almost lossless energy transfer in biomolecular chains or lattices as wave-like propagations of coupled conformational and electronic disturbances.
