Dietary restriction enhances the expression of the circadian clock genes in the peripheral tissue of fruit flies, according to research from the Kapahi lab at the Buck Institute. Publishing in Cell Metabolism, the researchers ...

Tomato domestication decelerated the circadian clock

All organisms, from bacteria to humans, exhibit endogenous rhythms controlled by the circadian clock. These rhythms are important for synchronization with the environment. Scientists at the Max Planck Institute for Plant ...

UT study: Lack of ZZZZs may zap cell growth, brain activity

Lack of adequate sleep can do more than just make you tired. It can short-circuit your system and interfere with a fundamental cellular process that drives physical growth, physiological adaptation and even brain activity, ...
