    Wardill, Trevor J.; Gonzalez-Bellido, Paloma T.; Crook, Robyn J.; Hanlon, Roger T. (2012-07-25)
    Fast dynamic control of skin coloration is rare in the animal kingdom, whether it be pigmentary or structural. Iridescent structural coloration results when nanoscale structures disrupt incident light and selectively reflect ...
  • Neuronal calcium sensor-1 enhancement of InsP3 receptor activity is inhibited by therapeutic levels of lithium
