It’s that time of year. The granting of the MacArthur awards and the Nobel Prizes. Which included 3 guys who were awarded the Nobel Prize for Physiology or Medicine for advancing the state of the art when it comes to circadian rhythms. And, the awardees didn’t devote their work solely to humans, but animals and plants, as well. (Amazingly, circadian rhythms affect disease susceptibility, growth rates- even the size of fruits that are grown.)
