ABSTRACT Recent work in blind human subjects has confirmed the presence of a non-visual ocular photoreceptive mechanism similar to that described in blind mice. This system appears to subserve circadian photic entrainment, the pupillary light response, and a number of other aspects of neurophysiology and behavior.

    ABSTRACT: Brain aging is linked to certain types of neurodegenerative diseases and identifying new therapeutic targets has become critical. Melatonin, a pineal hormone, associates with molecules and signaling pathways that sense and influence energy metabolism, autophagy, and circadian rhythms, including insulin-like growth factor 1 (IGF-1), Forkhead box O (FoxOs), sirtuins and mammalian target of rapamycin (mTOR) signaling pathways. This review summarizes the current understanding of how melatonin, together with molecular, cellular and systemic energy metabolisms, regulates epigenetic processes in the neurons. This information will lead to a greater understanding of molecular epigenetic aging of the brain and anti-aging mechanisms to increase lifespan under healthy conditions.

    ABSTRACT: The historical development of lighting technologies has been characterized by what evolution theorists call 'punctuated equilibrium': a succession of long periods of stable development followed by short periods of rapid change when key technological breakthroughs give rise to new lighting paradigms. Nowadays with the massive deployment of LED-based solid state lighting systems the illumination field is undergoing one of such accelerated transformation events. In parallel, a growing body of research has unveiled some of the complex interactions between the daily cycles of light and darkness and the regulating mechanisms of individuals, populations and ecosystems, including humans. This communication addresses some of the challenges that this new situation poses for the development of sustainable lighting systems.
