    Cryptochromes are evolutionarily conserved blue light receptors with many roles throughout plant growth and development. They undergo conformational changes in response to light enabling interaction with multiple downstream ...
  • The Quantum Biology of Reactive Oxygen Species Partitioning Impacts Cellular Bioenergetics 

    Usselman, Robert J.; Chavarriaga, Cristina; Castello, Pablo R.; Procopio, Maria; Ritz, Thorsten; Dratz, Edward A.; Singel, David John; Martino, Carlos F. (2016-12-20)
    Quantum biology is the study of quantum effects on biochemical mechanisms and biological function. We show that the biological production of reactive oxygen species (ROS) in live cells can be influenced by coherent electron ...
  • Animal models of osteogenesis imperfecta: Applications in clinical research 

    Enderli, Tanya A.; Burtch, Stephanie R.; Templet, Jara N.; Carriero, Alessandra (2016)
