A study using more than 27,000 sleep records of collegiate athletes provides the best evidence to date that early morning team practices take a toll on healthy sleep.

A new study by researchers from Duke-NUS Medical School has revealed that almost all community-dwelling older adults with advanced dementia in Singapore experience at least one potentially burdensome intervention in their last year of life.

Researchers have studied developments since the introduction of 'National knowledge support for good palliative care at the end of life' in 2013.

A new study led by Yale's Jennifer Miller, PhD, found that medicines are not physically accessible in many of the countries where they are tested for FDA approval.

A rare glimpse into the brain activity of a patient with obesity and loss of control eating on tirzepatide, marketed as Mounjaro and Zepbound, revealed that the medication suppresses signaling in the brain's "reward center" thought to be involved in food noise – but only temporarily.

Medicaid expansion under the Affordable Care Act (ACA) significantly increased the number of people at risk of HIV diagnosis who were prescribed preexposure prophylaxis (PrEP), a preventative medication taken in pill or injectable form, according to Rutgers Health–led research.

Dietary flavonoids from everyday foods show modest but promising benefits for mood, with the strongest evidence emerging from chronic, anthocyanin rich interventions. Acute effects are mixed, but longer term intake may support emotional well being through mechanisms involving monoamine activity and neuroplasticity.

A landmark international study finds that hospitals with better nurse staffing and work environments not only benefits nurses but is significantly associated with less physician burnout and job dissatisfaction.

Researchers at Oregon Health & Science University's Center for Women's Health have identified recent national trends in cesarean births, noting significant racial and ethnic disparities.

Higher maternal BMI before pregnancy is linked to increased risks of epilepsy and intellectual disability in young children, even after extensive adjustment for maternal and neonatal factors. Associations with autism spectrum disorder and ADHD disappear after full adjustment, highlighting the potential mediating role of perinatal complications.

Higher adherence to the Mediterranean diet was not associated with better cognition when wine was scored as a “beneficial” component. When wine was reverse scored, Mediterranean diet adherence showed a modest positive association with MMSE performance and a borderline link with MoCA in Portuguese older adults at high dementia risk.

For decades, scientists have known that mitochondria, which produce energy inside our cells, malfunction in Parkinson's disease.

Genetic susceptibility to neurodevelopmental conditions such as schizophrenia, autism, and ADHD can be linked, in part, to distinct epigenetic signatures in newborn cord blood.

Vision is one of the most fundamental senses, shaping how we perceive, navigate and interact with the world around us. Yet for more than 12 million Americans living with visual impairments, even small deficits can profoundly impact daily life, limiting independence and overall quality of life.

About a quarter of U.S. service members and veterans who start psychotherapy for post-traumatic stress disorder quit before they finish treatment.

Harnessing the muscle of one of the world's fastest supercomputers, researchers have built one of the largest and most detailed biophysically realistic brain simulations of an animal ever.

Fossil fuels release pollutants into the air when extracted and burned, but there's more to their production than massive oil rigs diving deep into the Earth and smoky power plants.

Researchers from Tokyo Metropolitan University have applied ideas from polymer physics to illuminate the mechanism behind a key pathology in Alzheimer's disease, the formation of fibrils of tau proteins.
