Fluctuations in light intensity allow restoring the regularity of circadian rhythms. This is the main conclusion of the work carried out by Javier Buceta, group leader of The SiMBioSys Group ( ...
... second study traced protein interactions throughout the cycles to demonstrate how phosphorylation controls circadian rhythm. Using a heavy isotope labeling method and quantitative mass spectrometry, ...
... and when we eat. This human clock manages what are known as circadian rhythms, 24-hour biological cycles that adapt our bodies to the light-dark pattern of day and night.
... Charles Wingo and his colleagues, at the University of Florida, Gainsville, suggests a link between the circadian rhythm and control of sodium (salt) levels in mice. The hormone aldosterone regulates ...
New research suggests a link between the circadian rhythm and control of sodium (salt) levels in the blood of mice. Specifically, the circadian clock protein Period 1 was found to function downstream ...
Circadian rhythms are 24-hour cycles in various biological processes like core body ... . showed that red light, which does not stimulate the circadian system, is just as effective at increasing night- ...

He and colleagues have had their research, currently focusing on the circadian rhythm in chickens' eyes, published in the "Journal of Biological Chemistry." Chicken eyes ...
... the foundation for our perception of color — with the visual system. Thus, in principle, the circadian system may be able to distinguish between lights of different colors.
