File this one under “enabler research.”
Scientists at Chapel Hill University studied the effects of UV radiation on mice when the mice were exposed at regular intervals: one group at 4am the other at 4pm. They found that the evening-dose mice were able to repair broken DNA strands, thus lowering their susceptibility to cancer. The theory goes that, since mice are nocturnal and their circadian rhythm is opposite ours, going to Guido’s House of Chicken Nugget Skin in the morning would have a comparably less-damaging effect on human bodies.
Of course, “less-harmful” is not quite the same thing as “not harmful,” but I suppose safety is a state of mind…
