Circadian sleep disorders are common among American adults and can become especially acute among older adults, especially those living with Alzheimer's disease (AD) and mild cognitive impairment (MCI), leading to the exacerbation of symptoms and contributing to the development and advancement of the diseases. This review explores the connections between circadian sleep disorders, cognition, and neurodegenerative disease, offering insights on rapidly developing therapeutic interventions employing intermittent light stimuli for improving sleep and cognition in persons with AD and MCI. Light therapy has the potential to affect sleep and cognition via at least two pathways: (1) a regular and robust light-dark pattern reaching the retina that promotes circadian phase shifting, which can promote entrainment and (2) 40 Hz flickering light that promotes gamma-wave entrainment. While this is a new area of research, preliminary evidence shows the potential of dual circadian and gamma-wave entrainment as an important therapy not only for those with AD, but for others with cognitive impairment.

Solar desalination shows promise in tackling freshwater shortages, but challenges arise from the trade-off between water transportation and heat supply, affecting evaporators' efficiency and salt resistance. Additionally, intermittent nature of solar radiation significantly diminishes overall evaporative performance. This study presents dual-gradient heating solar evaporator for efficient desalination.

Rationale: Gong's brain acupuncture (GBA) is a acupuncture technique that restores the balance of the central nervous system by stimulating specific acupoints on the skull to transmit stimulation to the nerves. Insomnia during pregnancy is an increasingly concerning issue, and GBA provides new solutions.
Patients Concerns: The patient, a 26-year old woman at 26 + 1 weeks of pregnancy, presented with unexplained insomnia for 3 weeks.

With the recent rise in the rate of alcohol use disorder (AUD) in women, the historical gap between men and women living with this condition is narrowing. While there are many commonalities in how men and women are impacted by AUD, an accumulating body of evidence is revealing sex-dependent adaptations that may require distinct therapeutic approaches. Preclinical rodent studies are beginning to shed light on sex differences in the effects of chronic alcohol exposure on synaptic activity in a number of brain regions.

Supplementation with far-red light in controlled environment agriculture production can enhance yield by triggering the shade avoidance syndrome. However, the effectiveness of this yield enhancement can be further improved through intermittent far-red light supplementation. In this study, the effects are explored of varying far-red light photon intensities and intermittent exposure durations-specifically at 5, 15, 30, and 45 min intervals-on the growth and development of lettuce () in plant factories, while maintaining a constant red light photon flux and daily light integral.

Objective: To determine the seasonal differences in instrumental activities of daily living (IADL) and objective physical activity among older adults residing in non-urban areas in snowy and cold regions according to sex.
Patients And Methods: Fifty older adults aged ≥65 years were included in the present study. IADL was assessed using the revised Frenchay Activities Index (FAI), and physical activity was measured using a triaxial accelerometer.
