Prior analyses have suggested light-based regulatory systems controlling spore production.
Previous research has suggested using light to manipulate the activity of neurons can reduce the protein in some regions of the brain.
The protective effect of physical activity becomes apparent with moderate-intensity exercise such as walking [ 6], although recent data in older adults has suggested that light activity also confers benefit in reducing the risk of type 2 diabetes [ 7].
Light is a key driver in the A. thaliana circadian clock, and a recent study has suggested a light-specific degradation rate for CCA1, a core partner of LHY (Yakir et al., 2007), and a current model for the A. thaliana clock uses different degradation rates for the LHY/CCA1 component in light and dark (Pokhilko et al., 2012).
As my colleague Howard Covitz has suggested, red lights at intersections are to be obeyed, even with no other car in sight in the wee hours.
But as President-elect Bush has suggested, that the lights of today tell us little about tomorrow.
But recent work by Samer Hattar at the University of Maryland has suggested that the light-sensitive cells in the eye, which control the circadian system, also connect to the homeostatic system.
Recent observations of the bright optical counterpart of GRB 080319B, whose light curve was correlated with the gamma-ray light curve, has suggested that inverse Compton may be the dominant process in some events.
Astronomers do not ask, for example, what purpose or function the Moon serves (though many a wag has suggested that it was designed to light the way home for drunken philosophers).
Evidence has suggested that excessive noise and continuous light exposure are common in ICU settings [ 4, 8, 13- 15].
