Researchers devise a new way to plot circadian clock
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 ...
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 ...
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 ...
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.
'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.
Symbiotic bacteria program daily rhythms in squid using light and chemicals
Glowing bacteria inside squids use light and chemical signals to control circadian-like rhythms in the animals, according to a study to be published on April 2 in mBio, the online open-access journal of the American Societ ...
Second body clock discovered in the speckled sea louse
The diminutive speckled sea louse (Eurydice pulchra) boasts two body clocks, one for night and day and another for the ebb and flow of the tide, according to research published today.
New pattern in our biological clock overturns long-held theory
(PhysOrg.com) -- University of Michigan mathematicians and their British colleagues say they have identified the signal that the brain sends to the rest of the body to control biological rhythms, a finding that overturns ...
Plants let chloroplasts know the time
(Phys.org) —Plant cells communicate information about the time of day to their chloroplasts, the part of their cells that underpins all agricultural productivity on Earth, researchers at the University ...
It's in the genes: Research pinpoints how plants know when to flower
Scientists believe they've pinpointed the last crucial piece of the 80-year-old puzzle of how plants "know" when to flower.
Putting the clock in 'cock-a-doodle-doo'
Of course, roosters crow with the dawn. But are they simply reacting to the environment, or do they really know what time of day it is? Researchers reporting on March 18 in Current Biology have evidence that p ...
Circadian clock research may enable designer plants, and cancer and diabetes treatments
How does a plant know when to sprout a leaf, fold its petals or bloom? Why do humans experience jet lag after a trip abroad?
