Time Restricted Feeding to the Light Cycle Dissociates Canonical Circadian Clocks and Physiological Rhythms in Heart Rate [PDF]
Frontiers in Pharmacology, 2022 Circadian rhythms are approximate 24-h biological cycles that optimize molecular and physiological functions to predictable daily environmental changes in order to maintain internal and organismal homeostasis.

Activation of the PACAP/PAC1 Signaling Pathway Accelerates the Repair of Impaired Spatial Memory Caused by an Ultradian Light Cycle [PDF]
ASN Neuro, 2023 The mechanism of light-induced spatial memory deficits, as well as whether rhythmic expression of the pituitary adenylyl cyclase-activating polypeptides (PACAP)-PAC1 pathway influenced by light is related to this process, remains unclear.

Timing of feeding mitigates metabolic effects of circadian disruption [PDF]
npj Biological Timing and SleepDisrupted light-dark cycles and mistimed feeding are recognized metabolic stressors. In this study, we investigated the independent and combined effects of a 12:12 light:dark cycle, advanced by 6 h every 6 days (Chronic Disruption; CD), and time ...

Lighting for cycling in the UK—A review [PDF]
Lighting Research & Technology, 2015 While UK governments have recently sought to increase cycling activity, it remains a minority interest. One reason for this is the perceived danger of cycling on roads filled with traffic. There is statistical evidence to support this perception; for equal exposure, cyclists are more likely to be seriously injured than either drivers or pedestrians ...
