Les couleurs, nous les voyons, mais nous rendons-nous vraiment compte de l’influence qu’elles ont sur nous? Dans un monde moderne qui privilégie les tons neutres et dénaturés, Jean-Gabriel, auteur du livre « Létonnant pouvoir des couleurs » éclaire notre regard sur la couleur.
Every organ and even every cell in our body has circadian or 24 h clock. Circadian clocks turn on and off thousands of genes at the right time of the day or night. These rhythms work together to maintain healthy balance of brain chemicals, hormones, and nutrients. When our rhythms break down we are more likely to suffer from a wide range of diseases from depression to cancer. We can tune our daily habits of eating, sleeping or getting the right amount of light to sustain our circadian rhythms. Healthy rhythms nurture healthy body and healthy mind. Dr. Satchidananda Panda, a professor at the Salk Institute for Biological Studies in La Jolla, California. Satchin’s work deals specifically with the timing of food and it’s relationship with our biological clocks governed by circadian rhythm and also the circadian rhythm in general.
Professor Panda explores the genes, molecules and cells that keep the whole body on the same circadian clock. A section of the hypothalamus called the suprachiasmatic nucleus (SCN) lies at the center of the body’s master clock and gets input directly from light sensors in the eyes, keeping the rest of the body on schedule. Panda discovered how these light sensors work, as well as how cellular timekeepers in other parts of the body function. He also uncovered a novel blue light sensor in the retina that measures ambient light level and sets the time to go to sleep and wake up every day.
In the process of exploring how the liver’s daily cycles work, Panda found that mice which eat within a set amount of time (12 hours) resulted in slimmer, healthier mice than those who ate the same number of calories in a larger window of time, showing that when one eats may be as important as what one eats. If the benefits of this “12-hour diet” hold true in humans, it could have profound impacts on treating overeating disorders, diabetes and obesity.
The circadian clock, he found, even mediates the immune system. Mice with a crucial circadian molecule missing had higher levels of inflammation in their bodies than other mice, suggesting that genes and molecules involved in the circadian clock could be drug targets for conditions linked to inflammation, such as infections or cancer.

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
