Determining the differences between short and normal period clocks in spiders may help researchers find out why and how different circadian clocks are suited to the particular environmental challenges of each species, Moore said.

For photosynthetic bacteria, every night is a period of starvation, and it is likely that the circadian clock helps them grow during the day in order to prepare for nightfall.

But flies with mutations in the circadian clock genes called period, clock, cycle, and doubletime never became habituated to the drug, even after repeated exposures.

Two clock proteins, CLOCK (Circadian locomoter output cycles protein kaput) and BMAL1 (Brain and Muscle Arnt - like1) bind to each other to form a heterodimer complex, which then binds to a DNA sequence called E-box (CACGTG) located in the upper region of clock genes, Per (Period) and Cry (Cryptochrome), present in the geclock proteins, CLOCK (Circadian locomoter output cycles protein kaput) and BMAL1 (Brain and Muscle Arnt - like1) bind to each other to form a heterodimer complex, which then binds to a DNA sequence called E-box (CACGTG) located in the upper region of clock genes, Per (Period) and Cry (Cryptochrome), present in the geCLOCK (Circadian locomoter output cycles protein kaput) and BMAL1 (Brain and Muscle Arnt - like1) bind to each other to form a heterodimer complex, which then binds to a DNA sequence called E-box (CACGTG) located in the upper region of clock genes, Per (Period) and Cry (Cryptochrome), present in the geclock genes, Per (Period) and Cry (Cryptochrome), present in the genome.

Virtually every organism on the planet — from bacteria to humans — has a circadian clock, a biological timing mechanism that oscillates with a period of about 24 hours and is coordinated with the cycle of day and night.

Further investigation showed that DHEA shortens the period of the circadian clock in cultured human cells in a dose dependent manner.

«Our circadian rhythm or body clock plays an important role in the timing of our sleep period,» says Dr Helen Wright from the School of Psychology at Flinders University.

According to Dr. Lori Rose, who is my co-author for this post, that's because our digestive tract contains a «peripheral body clock» that syncs up with our 24 - hour circadian rhythm, and periods of daily feasting / fasting help «set» the clock in the same way that light and dark does.
