The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

New NATO guidelines aim to protect soldiers' brains from blast exposures

Two University of Virginia researchers helped develop new NATO guidelines for protecting soldiers' brains from blast exposures common in military combat and training.

Dysfunctional myelin-producing brain cells contribute to age-related cognitive decline

Brain cells that produce the protective coating around nerve fibers can become dysfunctional with age and may actively contribute to cognitive decline, according to new research.

Loneliness can reprogram the brain to increase alcohol use

Loneliness can reprogram the brain in ways that push alcohol consumption, reports a new preclinical study led by Northwestern University and the Salk Institute for Biological Studies.

Study reveals high prevalence of chronic traumatic encephalopathy among former NFL players

At minimum, nearly a quarter of all former National Football League (NFL) players who died from 2016 to 2021 had confirmed chronic traumatic encephalopathy (CTE) – a neurodegenerative disease linked to repeated head impacts – at death, finds a study published by The BMJ today.

New machine learning tool identifies hidden epigenetic disease patterns

In a study recently published in Nature Communications, researchers from Berlin, Potsdam, and Jena present a new method for analyzing the epigenome, the genome's control system that determines which genes are switched on and off.

New review challenges the eight-hour ancestral sleep myth

Everyone knows the number. Eight hours. It sits on wellness dashboards, on pediatric handouts, on the label of the melatonin bottle in the medicine cabinet.

Mitochondrial transplantation helps repair donor organs during machine perfusion

Transplant medicine still depends on a limited supply of donor organs, while many retrieved grafts are discarded because ischemia, cold storage, and reperfusion can rapidly damage their cells.

The diet-Alzheimer’s connection is more complicated than “eat this, avoid that”

A mini-review finds that dietary patterns may influence Alzheimer’s disease through interconnected pathways involving neuroinflammation, insulin resistance, oxidative stress, blood-brain barrier dysfunction, homocysteine, and the gut-brain axis. The authors argue that genetics, sex, age, physical activity, and socioeconomic context may modify these relationships, supporting more individualized approaches to nutrition research and dementia prevention.

Scientists compared 51 longevity studies to see which aging biomarkers respond most reliably

Researchers analyzing 51 longitudinal intervention studies found that reliable generation 2+ DNA methylation biomarkers, particularly those predicting mortality or pace of aging, were the most responsive to interventions aimed at longevity or healthspan. Pharmacological and lifestyle interventions produced the strongest biomarker changes, but the authors cautioned that responsiveness does not yet establish these measures as validated surrogate endpoints for slower aging or longer life.

Shared protein pathology redefines treatment for multiple neurodegenerative diseases

On the surface, amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD) and limbic-predominant age-related TDP-43 encephalopathy (LATE) might seem like unrelated diseases.

Researchers explore the link between tau levels and depressive symptoms in older people

During typical aging and Alzheimer's disease progression, higher levels of a protein called tau are associated with more depressive symptoms.

Short workouts or naps protect memory after sleep deprivation

A short workout or a nap can help protect memory after a sleepless night, a McGill University-led study has found.

Survey provides a comprehensive snapshot of youth mental health and drug use in Ontario

Findings from the 2025 Ontario Student Drug Use and Health Survey (OSDUHS) released today by the Centre for Addiction and Mental Health (CAMH) suggest that Ontario middle and high school students have rebounded from the heightened mental health challenges seen during and immediately following the COVID-19 pandemic.

Older brains' language processing network remains resilient to aging

As people age, many cognitive functions tend to decline. Brain scanning studies have revealed corresponding changes in the function of a brain network that is involved in many of these cognitive functions, including working memory and problem-solving.

Review uncovers how tryptophan metabolism affects female reproductive health

In recent years, issues concerning female reproductive health have become a global challenge that cannot be ignored.

Multi-target interventions may yield superior outcomes for chronic ankle instability

Ankle sprain is the most prevalent sports-related injury affecting the lower limbs, and up to 70% of individuals with ankle sprain experience persistent symptoms, such as sensorimotor impairment and balance deficits, which may ultimately progress to chronic ankle instability (CAI).

Fruit fly brain inspires energy-efficient scent classification algorithm

In the animal kingdom, energy conservation is essential for survival. That's why our brains have evolved to be extremely energy and resource efficient at storing and processing information.

Disrupted brain-immune signaling may help drive neurodegeneration

A Cell perspective argues that neurodegeneration can emerge from disrupted communication between neural and immune networks, with peripheral immunity, microglia, and gene-regulatory programs all shaping disease processes. The authors propose that restoring immune homeostasis and recalibrating neuroimmune circuits could create new therapeutic and diagnostic opportunities, while emphasizing that many mechanisms remain unresolved in humans.

A childhood shaped by sugar rationing was linked to mental health more than 50 years later

UK Biobank researchers examined whether sugar rationing during pregnancy and the first two years of life was associated with adult sweet-food preferences, sugar intake, brain structure, anxiety, and depression.

FDA clears innovative blood test for earlier Alzheimer's diagnosis

The U.S. Food and Drug Administration (FDA) has cleared for marketing an innovative blood test with underlying technology invented at Washington University School of Medicine in St. Louis for the early diagnosis of Alzheimer's disease.
