How do researchers study circadian rhythms?
Scientists can study circadian rhythms by studying humans or by using model organisms, such as mice or even algae. Basic researchers doing these experiments control the subject’s environment by altering light and dark periods and then look for changes in gene activity or other molecular signals.

How does circadian rhythm research contribute to human health?

Understanding what makes our biological clocks tick may lead researchers to treatments for sleep disorders, jet lag and other health problems. Learning more about the genes responsible for circadian rhythms will also enhance our understanding of biological systems and the human body.

How does circadian rhythm research contribute to agriculture?
A better understanding of plant circadian rhythms has applications in agriculture such as helping farmers stagger crop harvests thus extending crop availability, and to secure against massive losses due to weather
