biological clock

However, stress can speed up the biological clock, making people more vulnerable to aging-related diseases, from cardiovascular disease to diabetes and dementia.

However, like all living things, plants are subject to a circadian rhythm -- the biological clock that runs through day and night cycles and influences biological processes.

These results imply that the expression rhythms of genes controlled by the biological clock are sensitive to environmental changes, and can be influenced by genetic changes that result from environmental adaptation.

Some proteins had rhythms closely tied to the master biological clock, which keeps the body on a 24-hour rhythm.

So much for beating the biological clock, as promised by a multimillion-dollar industry that promoted its technologies in part as a way for women to avoid detrimental career disruptions.
