Scientists at Thomas Jefferson University have identified two new genes, taranis and Cyclin-dependent kinase 1 (Cdk1), as crucial for regulating normal sleep patterns in flies. The researchers found that these genes interact with other proteins to create a molecular machine that suppresses wakefulness and promotes sleep.
A study of 39 female shift-working nurses found that longer rest periods between shifts improved recovery from work, as measured by increased parasympathetic activation and decreased sympathetic activation during sleep. This suggests that a forward-rotating shift system can promote better coping and well-being at work.

A new study links lower life satisfaction to sleep problems during midlife, finding that shorter sleep onset latency is associated with higher life satisfaction. The research suggests that improving one variable, such as sleep quality, may have a positive impact on another, like life satisfaction.
A new study found that infants who can resettle themselves after waking up are more likely to sleep for prolonged periods at night. By three months of age, most infants develop this ability, which is associated with longer sleep durations and reduced crying at night.
A new study found that patients with knee osteoarthritis who have poor sleep habits display greater central sensitization, an amplification of clinical pain. Catastrophizing thoughts about pain also contribute to increased central sensitization and greater clinical pain in OA patients.
A new study from the University of Pennsylvania found that specific types of physical activity are associated with better sleep habits. These include aerobics/calisthenics, biking, gardening, golfing, running, weight-lifting, and yoga/Pilates. In contrast, household and childcare work were linked to insufficient sleep.

A new study finds that shift workers are more likely to be overweight and experience sleep problems, increasing the risk of metabolic disorders like diabetes. Sufficient sleep may partially alleviate these adverse health effects.
A multinational study found that children with a consistent bedtime routine had better sleep outcomes, including earlier bedtimes and increased sleep duration. The positive impact of bedtime routines on sleep increases with consistency and age, making it a simple yet effective step for families to improve their child's sleep.
Researchers found obesity and depression to be underlying causes of regular drowsiness, with low-grade chronic inflammation a primary mechanism for fatigue in obese individuals. Depressed individuals also experienced high incidence of EDS, likely due to physiologic sleep disturbances.
A recent QUT study suggests that excessive mandatory napping in childcare settings is associated with reduced nighttime sleep duration. The research found that children who received over an hour of mandatory naptime had, on average, 24 minutes less night-time sleep when in childcare.
A comprehensive survey of nearly 1,000 toddlers reveals that serious sleep disorders can have long-term consequences for mental health. Four-year-olds with sleep disorders are at higher risk of developing psychiatric symptoms as six-year-olds, while those with psychiatric symptoms are more likely to develop a sleep disorder.

A new app developed at the University of Washington uses inaudible sound waves to track breathing patterns, capturing sleep apnea events with 98% accuracy. The app has the potential to be a simple and noninvasive way for people to identify and potentially treat sleep apnea.
A new study links insomnia to occupational impairment in night shift workers, with alert insomniacs showing the highest level of impairment in work productivity and cognitive function. The study emphasizes the importance of treating insomnia in night shift workers to improve work-related outcomes.
A study found that many magazine images and stock photos of infants show them sleeping on their stomachs or with soft objects, increasing the risk of sudden infant death syndrome. Only about half of the stock photos and a third of magazine pictures depicted safe sleep environments according to AAP guidelines.
A recent study published in The Journal of Pediatrics reveals that improper use of infant sitting and carrying devices can lead to fatal accidents. The researchers analyzed records of 47 deaths associated with these devices, finding that two-thirds involved car seats and strangulation from straps was the leading cause of death.
Researchers found that extra sleep can restore memory formation in fruit flies with disrupted genes, similar to Alzheimer's disease. The study suggests that sleep helps reinforce connections between brain cells and cut back on useless information.
A new study found that wind instrument players have a reduced risk of developing obstructive sleep apnoea. The researchers believe this is due to increased muscle tone in the upper airways, common among wind instrument players.
A study found that sleep disordered breathing can negatively impact declarative memory, making it harder for children to consciously recall learned information. Non-declarative memory, which involves learning new skills through reaction times, was less affected by sleep disturbances.
A new study published in Neurology suggests that heavy snoring and sleep apnea may be linked to an earlier age of memory decline. Treating the disorders with a breathing machine may delay the decline, according to the research.
While some health apps have shown promise in improving weight loss and physical activity, others have yielded conflicting results. Iltifat Husain argues that doctors should recommend tested and validated apps to help people stay healthy. Des Spence cautions that many health apps are untested and may even cause anxiety and medical harm.
