CBC -The Nature of Things with David Suzuki - - Lights Out! - Recently scientists have been discovering that exposure to artificial light at night, even the glow of a cell phone or computer screen, can throw our internal body clock out of sync with the planet and may even be leading to serious illnesses like cancer, obesity, heart disease and certain forms of depression.

Circadian Rhythms Linked to Aging and Well-Being | The inner-workings of the "circadian clock" are complex. The molecular processes behind it have eluded scientists until now. Two new studies from June 2013 have uncovered specific proteins that drive circadian cycles. Although it is possible for circadian cycles to function without external cues, these cycles are influenced primarily by the rhythms of light, temperature, and food availability.

Electric lighting prevents proper nights sleep |  Electric lighting prevents us getting a proper nights sleep because it gives us a second wind before bedtime when our body clocks should be winding down, researchers claim.

Creatures of the deep: terrifying macro pictures of polychaetes or bristle worms

What's the Big Idea?    It's long been known by scientists that blue light increases alertness by stimulating special cells on the retina, which in turn reduces melatonin secretions. However, until now no tests had been done involving complex tasks like driving. So long as the blue light doesn't distract -- eight of the 48 subjects could not participate because of the light -- it appears to be about as good as coffee for keeping drivers alert, and could possibly be installed in future…
