Liberating clocks: Developing a critical horology to rethink the potential of clock time [PDF]
, 2017 Across a wide range of cultural forms, including philosophy, cultural theory, literature and art, the figure of the clock has drawn suspicion, censure and outright hostility.

Distinguishable DNA methylation defines a cardiac-specific epigenetic clock
Clinical Epigenetics, 2023 Background The present study investigates whether epigenetic differences emerge in the heart of patients undergoing cardiac surgery for an aortic valvular replacement (AVR) or coronary artery bypass graft (CABG).

Quantitative analysis of regulatory flexibility under changing environmental conditions [PDF]
, 2010 The circadian clock controls 24-h rhythms in many biological processes, allowing appropriate timing of biological rhythms relative to dawn and dusk. Known clock circuits include multiple, interlocked feedback loops.

Making Memories: Why Time Matters [PDF]
, 2018 In the last decade advances in human neuroscience have identified the critical importance of time in creating long-term memories. Circadian neuroscience has established biological time functions via cellular clocks regulated by photosensitive retinal ...

Circadian and Geotactic Behaviors: Genetic Pleiotropy in Drosophila Melanogaster
Journal of Circadian Rhythms, 2016 Data presented in this paper test the hypotheses that Hirsch’s positive geotaxis ('Lo') and negative geotaxis ('Hi5') strains of Drosophila melanogaster (fruit fly) differ in length of the free-running circadian activity period (tau) as well as adult ...

Light and circadian regulation of clock components aids flexible responses to environmental signals [PDF]
, 2014 The circadian clock measures time across a 24h period, increasing fitness by phasing biological processes to the most appropriate time of day. The interlocking feedback loop mechanism of the clock is conserved across species; however, the number of loops

In Synch but Not in Step: Circadian Clock Circuits Regulating Plasticity in Daily Rhythms [PDF]
, 2016 The suprachiasmatic nucleus (SCN) is a network of neural oscillators that program daily rhythms in mammalian behavior and physiology. Over the last decade much has been learned about how SCN clock neurons coordinate together in time and space to form a ...

Circadian rhythm and cell population growth [PDF]
, 2010 Molecular circadian clocks, that are found in all nucleated cells of mammals, are known to dictate rhythms of approximately 24 hours (circa diem) to many physiological processes.

What season suits you best? Seasonal light changes and cyanobacterial competition [PDF]
, 2015 Nearly all living organisms, including some bacterial species, exhibit biological processes with a period of about 24 h called circadian (from the Latin circa, about and dies, day) rhythms.

Nature AgingWhile observational studies and small pilot trials suggest that vitamin D, omega-3 and exercise may slow biological aging, larger clinical trials testing these treatments individually or in combination are lacking.
