Nothing in biology is static. Biological processes fluctuate over time, and if we are to put together an accurate picture of cells, tissues, organs etc., we have to take into account their temporal patterns. In fact, this effort has given…

Study suggests the impact of non-coding microRNAs on circadian rhythms is tissue specific and may reveal new insights into disease processes If you've ever had a bad case of jet lag, you know how a disruption to your body's circadian…

Study by Brazilian and South African researchers is the first to prove, using a graph analysis tool, that REM dream narratives tend to be more complex and connected than reports of non-REM dreamsCredit: Mariana Muniz Some dreams are so…

BLOOMINGTON, Ind. -- During the pandemic, the amount of screen time for many people working and learning from home as well as binge-watching TV has sharply increased. New research finds that wearing blue-light glasses just before sleeping…

Chronic jet lag creates favorable cancer conditions in experimental models Imagine you've just arrived in Paris. Your body thinks it should be midnight - a restorative time when your cells typically proofread DNA, organize and store…

One potential cause of cancer is circadian disruption, the misalignment of environmental cues (light, food intake, etc.) and our endogenous circadian rhythms. It is established that regular physical activity throughout lifetime can reduce…
