Circadian rhythm in the cyanobacterium Spirulina platensis

Circadian rhythm constitutes key photobiological signals for successive growth of cyanobacteria in variable environment conditions (Cohen and Golden 2015). The endogenous property of diurnal rhythm may alter optimum growth and production of cyanobacterial products in variable environmental

The clockwork behind depression

Globally, an estimated 350 million people of all ages suffer from depression and the number is increasing. Currently, we don’t know exactly what causes depression. However, what we do know is that depression and the circadian rhythm

Melatonin reduces blood pressure and tunes up disrupted circadian rhythms in the seniors

Later school start times improve sleep in high school students

Research conducted over the past four decades has shown that acquiring adequate sleep is a component of normal growth and development during childhood and adolescence. Adequate sleep is needed to achieve optimal mental and physical alertness, daytime

Design principle of CRY-acting compounds for regulation of the circadian clock

Almost every aspect of our life varies over time: we wake up in the morning, sleep at night, and become hungry at about the same time every day. This is called the circadian rhythm; an approximately 24-hour
