Scientists have discovered that DNA packaging proteins play a central role in the parasite's ability to alter its surface coat protein, enabling it to evade the host's immune system. This process, known as antigenic variation, allows trypanosomes to stay one step ahead of the game and establish long-term infections.
A novel antidepressant, vortioxetine, has been shown to improve subjective sleep quality and daytime sleepiness in patients with major depressive disorder. The treatment's multimodal effect on serotonin transport and reuptake may have important clinical implications for addressing sleep problems in depression.
Experts warn that cardboard baby boxes are being promoted without supporting evidence, posing risks to infant safety. The boxes may not meet safety regulations, have potential design flaws, and are not suitable for all age groups.
Researchers found that when mothers reported less flexibility in their work schedules, their children got less sleep. However, consistent bedtimes may be the key to offsetting damage done by tight work schedules. Employers can create policies to give employees more flexibility, which could help promote sleep health from childhood.
A new algorithm called SleepGuard tracks sleep patterns using multiple smartwatch sensors, estimating sleep quality and providing users with practical advice. The technology captures key factors such as body movements, ambient lighting, and sounds related to sleep disorders.

Researchers have found that Alzheimer's disease is closely linked to neuropsychiatric symptoms such as depression, anxiety, and sleep disturbances. The study used brains from over 1,000 healthy adults aged 50+, finding that AD pathology was present in many individuals who didn't show classic cognitive symptoms.
New research reveals identical brain mechanisms trigger memories during both sleep and wakefulness, suggesting a crucial role for sleep in stabilizing memories. The study provides further evidence of the beneficial effects of sleep on memory formation and offers insights into how memories are formed.
Scientists have discovered that a specific region of the brain, known as the ventrolateral preoptic nucleus (VLPO), plays a crucial role in regulating sleep and body temperature. Activating these cells causes a profound drive to sleep, while excessive stimulation can lead to prolonged sleep and a drop in body temperature.
A study by Columbia University's Mailman School of Public Health found that nearly one-third of Washington Heights residents experienced energy insecurity, leading to breathing problems, mental health issues, and poor sleep. Energy-insecure households were more likely to have children under 18 years of age and lower household income.
Researchers found that brain activity patterns during sleep can reveal which memories are stored and which forgotten. The brain reactivates memory traces during certain sleep phases, especially when gamma band activity from deep processing is reactivated during ripples in the hippocampus, leading to later recall of images.
Engineers at UC San Diego developed an algorithm to predict individual blood pressure based on sleep, exercise, and blood pressure data from wearable devices. The study found that personalized data was more effective than generalized information in lowering blood pressure.

A study by Rush University Medical Center found that Chicago news media reported 59% of child traffic crash deaths and 38% of fire-related deaths, but not a single case of sudden unexpected infant death. This lack of reporting contributes to parents' unawareness of the risks involved, leading to unsafe sleep environments.
A new study published in JAMA Internal Medicine found that one in four older adults prescribed benzodiazepines continue to use them long-term. The research highlights the need for better education and critical thinking among healthcare providers to reduce the risk of long-term use, particularly among low-income older adults.
A study of black women found that those who slept less than 7 hours a night had higher blood pressure and lower levels of physical activity. The researchers suggest that addressing sleep quality is crucial for combating obesity and high blood pressure in this population.

The research used mathematical modeling to compare the fitness of sleeping and non-sleeping strategies under various conditions.
A nationwide health study found that service workers, particularly those who rely on tips, are more susceptible to mental health issues such as depression and stress. The research team suggests that the precarious nature of service work, including lower wages and lack of control over work hours, may contribute to these findings.
A subset of dopaminergic neurons are inhibited during the day by light-responsive neuropeptide Pigment Dispersing Factor (PDF) and its receptor (PDFR), promoting wakefulness. High daytime levels of PDF increase daytime sleep, while reducing PDFR expression decreases daytime sleep.

Children and their parents experienced significantly less sleep than when sleeping at home, with an average loss of over an hour.
Researchers have found that non-invasive brain stimulation during sleep can improve memory consolidation and generalization. The study used a closed-loop transcranial alternating current stimulation system to synchronize brain activity during slow-wave oscillations, leading to enhanced performance in detecting targets in novel situations.
A new study published by the American Thoracic Society found that supplemental oxygen eliminated the rise in morning blood pressure experienced by OSA patients who stopped using CPAP. The study suggests that intermittent hypoxia is the dominant cause of daytime increase in blood pressure in OSA.
A new study found that following a Mediterranean diet was positively associated with academic grades and verbal ability in adolescents. The diet's effect on sleep quality may be an underlying factor contributing to these improvements.

The American Academy of Sleep Medicine has published a clinical practice guideline on the use of actigraphy in evaluating adult and pediatric patients with suspected sleep disorders. Actigraphy is recommended as a useful tool for gathering objective data on sleep habits, but not used as a substitute for polysomnography.
A study from Binghamton University found that individuals living in areas with lower sunlight exposure may have a higher risk of developing obsessive-compulsive disorder (OCD). The researchers suggest that reduced morning light exposure could disrupt the internal biology and external light-dark cycle, leading to increased OCD symptoms.
