Of flies and biological clocks
We awaken when the sun rises and go to sleep when the skies grow dark. We are animals of the daylight, and our waking and sleeping hours are determined by a biological clock. Who would have imagined that the mysteries of this internal timekeeper would be unraveled by researching the behavior of a fly—specifically, Drosophila melanogaster or, as it is more typically known, the fruit fly. This discovery will be the topic of conversation that Ramón Latorre will explore with Michael Rosbash, who in 2017 shared the Nobel Prize in Medicine with Michael W. Young and Jeffrey C. Hall for their discovery of a gene responsible for coding a protein that accumulates during the night and is degraded during the day, and is also the essential component of the fruit fly’s biological clock. Incredibly, the processes that the scientists discovered in the fly also apply to other plants and animals, including humans.
