Jen Schwartz, the Senior Editor for Scientific American, joins Lynn and John. In the July edition of the magazine, an article appeared called The Clocks Within Our Cells: How the Body’s Cycles Went From Folk Medicine to Modern Science. There’s a fascinating connection between our biology and time. Let’s call it the body clock. The 2017 Nobel Prize in Physiology or Medicine went to three circadian clock researchers who discovered a central clock protein that builds up in cells during the night, breaks down during the day and acts as a kind of crankshaft for the whole machine. The findings of circadian clock researchers imply that on the level of the organism, there is a good time and a bad time to do anything, even take Tylenol, for example.
