The circadian clock is like an orchestra with many conductors
You've switched to the night shift and your weight skyrockets, or you wake at 7 a.m. on weekdays but sleep until noon on weekends—a social jet lag that can fog your Saturday and Sunday.
Group finds circadian clock common to almost all life forms
Researchers devise a new way to plot circadian clock
Ancient body clock discovered that helps to keep all living things on time
The mechanism that controls the internal 24-hour clock of all forms of life from human cells to algae has been identified by scientists.
Scientists Discover Hunger's Timekeeper
(PhysOrg.com) -- Researchers at Columbia and Rockefeller Universities have identified cells in the stomach that regulate the release of a hormone associated with appetite. The group is the first to show that ...
Peak production of rhythmic proteins occurs at two times of day
Sleep disorders are reported to affect 50 to 70 million Americans, and have been linked to obesity and diabetes, as well as depression and other psychiatric disorders. Circadian cycles are driven by biological clocks that ...
Lipoic acid helps restore, synchronize the 'biological clock'
Researchers have discovered a possible explanation for the surprisingly large range of biological effects that are linked to a micronutrient called lipoic acid: It appears to reset and synchronize circadian ...
Atomic structure of essential circadian clock protein complex determined
Structural biologists have made important progress towards better understanding the functioning of the circadian clock. The circadian or inner clock coordinates the sleep-wake rhythm and many other body processes ...
Circadian clock's rhythm ensures steady energy supply to cells during times of fasting
Each of our cells has an energy furnace, and it is called a mitochondrion. A Northwestern University-led research team now has identified a new mode of timekeeping that involves priming the cell's furnace to properly use ...
Study finds variation in circadian clock protein in fruit flies
The circadian clock is a molecular network that generates daily rhythms, and is present in both plants and animals.
Plants use sugars to tell the time of day, study finds
Plants use sugars to tell the time of day, according to research published in Nature today.
Synthetic genetic clock checks the thermometer
(Phys.org) —Genetic systems run like clockwork, attuned to temperature, time of day and many other factors as they regulate living organisms. Scientists at Rice University and the University of Houston ...
Scientists throw light on the mechanism of plants' ticking clock
Scientists from the University of York are part of an international team of researchers who have made a significant step in discovering the genetic mechanisms that plants use to fight for light.
'Snooze button' on biological clocks improves cell adaptability
The circadian clocks that control and influence dozens of basic biological processes have an unexpected "snooze button" that helps cells adapt to changes in their environment.
