Summary: The study found that following a light exposure schedule can help male cricketers adapt to jet lag quicker after an 8.5-hour timezone change. On average, it took all participants 7 days to fully adapt to the new timezone, while subjective jet lag decreased within the same time frame.

Summary: Light has been found to affect the circadian clock of the human body, with the high-intervention group in this study effectively reducing the negative effects of phase-advance jet lag on alertness, improving memory task performance, and reducing visual fatigue. The results recommend the use of a high-intervention light scheme for adjusting phase-advance jet lag in interior public workplaces, showing a high correlation between light stimulus intensity and circadian phase shift.

Summary: The study found that eastward jet lag was associated with impaired performance for home teams in the NBA, while it did not significantly affect away team performance. Sleep and circadian disruption following eastward travel may lead to performance decrements, particularly when recovery time is limited.

Summary: The study reveals the role of Cry1 in phase shifting and longevity in the face of heart disease. The Cry1-deficient animals show increased phase volatility but not accelerated circadian clock. Additionally, phase shifts can eliminate the shortened lifespan effect of cardiomyopathy in these mutants.

Summary: Sleep is crucial for the recovery and performance of basketball players. The quality and duration of sleep are related to performance and injury risk. The circadian rhythm of players is also influenced by game scheduling.

Summary: Human circadian rhythmicity is influenced by the internal circadian clock, the sun, and social clocks. The discrepancy among these clocks, particularly when official time does not match its geographical time zone, can lead to circadian disruption. This study explored the effects of official time on circadian rhythmicity and sleep in elderly and retired populations in Western Spain and Portugal. The results showed that circadian robustness was greater in Portugal, especially during weekdays, while Spaniards experienced greater desynchronization. The findings suggest that misalignment between official time and geographical time zone can have a detrimental effect on the robustness of the circadian system.

Summary: This study assessed the physiological mechanism of jet lag induced by transmeridian travel and found that tasimelteon can be an effective therapeutic tool for treating jet lag disorder, improving sleep and daytime alertness.

Summary: Availability of artificial light and light-emitting devices have changed human temporal life, but exposure to artificial light at night disrupts circadian rhythms and increases the risk of metabolic and cardiac disorders. Circadian rhythms, regulated by the suprachiasmatic nucleus (SCN), control physiological processes such as sleep and food intake. Modern lighting disrupts the molecular clock rhythms, leading to hormonal and metabolic disruptions. Understanding these disruptions and developing strategies to mitigate their effects is crucial for human health.

Summary: The circadian clock in the mammalian brain regulates important physiological functions and is linked to neurological conditions related to dopamine imbalances. A mathematical model is used to explore the reciprocal influence between dopamine and the circadian clock, specifically the role of dopamine receptor D1 signaling in circadian entrainment. The effects of phase shifts, photoperiod, and therapeutic potential are studied, providing insights into the underlying mechanisms and potential treatments.

Summary: Physiologists have observed an increase in human muscle strength from morning to evening for over 20 years, which is suggested to be caused by intrinsic, nonneural muscle factors. Evaluating circadian clock data sets from human and mouse studies, possible mechanisms through which the muscle circadian clock may impact time-of-day muscle strength outcomes are highlighted.

Summary: Research on temporal trajectories of emotions shared on Twitter shows that positive and negative emotions follow nonlinear circadian and circaseptan patterns. Self-referential content is more relevant to individuals. Emotional expression in emojis sometimes diverges from textual analysis, indicating some complementarity.

Summary: Changing meal timing can rescue the cognitive and hippocampal impairments induced by HFD, even without altering body composition and total caloric intake. This suggests that short-term time-restricted feeding is an effective intervention for HFD-induced cognitive deficits and hippocampal dysfunction.

Summary: Circadian rhythms are driven by an endogenous clock located in the suprachiasmatic nucleus. Light signals can shift the rhythm, but abrupt changes in lighting conditions can cause jet lag. Modifying the amplitude of the circadian limit cycle can affect the length of phase shifts.

Summary: This paper presents a new two-stage network mediation method using a latent network approach and model-based eigenvalue decomposition for analyzing social network data. By controlling for conditional covariates and only considering the information left in the network, the method demonstrates its applicability to empirical network data.

Summary: The study found that daily measures of moral identity exhibited more between-person variability. Additionally, feelings of integrity and compassion were more strongly correlated with moral identity on the inter-individual level. Therefore, moral identity may have both trait and state-like characteristics.
