The science of biological timing

Today, the Nobel Prize Committee awarded the 2017 Prize in Physiology or Medicine to three American scientists - Jeffrey C. Hall, Michael Rosbash and Michael W. Young, for their discoveries of molecular mechanisms controlling the circadian rhythm.
From the press release:

Off course, there's no "clock" in the body. Biological organisms use protein accumulation cycle to adapt to the rotation of the Earth. It took nature billions of years to develop this amazing adaptation. Now, we are figuring out ways to understand and and adapt to innovation timing, i.e. cycles of new ideas, including science and technology.
