Discontinuous magnetic field effects (Barkhausen noise) in nucleic acids as evidence for room temperature organic superconduction. 
Magnetization in fields of 2,000 to 9,000 gauss at room temperature generates low frequency noise in the microwave electrical conductivity of hydrated nucleic acids or dry melanin.  The pattern of behavior observed for this noise suggests that it is analogous to Barkhausen noise observed during the penetration of bits of magnetic flux into type 2 superconductive metals.  This implies that hydrated nucleic acids and dry melanin contain superconducting regions at room temperature.
