A Swedish-led study validated a self-administered digital cognitive test (BioCog) in primary care, showing it can accurately detect objective cognitive impairment before blood biomarkers are applied. When paired with a targeted amyloid blood test, this stepwise pathway outperformed standard assessments for diagnosing clinical Alzheimer’s disease.

This global analysis shows that the biodiversity impact of producing 1 kg of food can vary by up to 1,000-fold, with ruminant meat and tropical luxury crops carrying the highest extinction risks. Using the LIFE metric, researchers reveal how national diets and food imports contribute to hidden biodiversity losses, highlighting dietary shifts as a powerful conservation tool.

Self-administered dried blood spot kits show potential for cardiometabolic screening in young adults, but success relied heavily on clear guidance and researcher support. High rates of at-risk biomarkers highlight an urgent need for early prevention in this population.

Researchers modeled drone-based medication delivery across Virginia’s isolated Eastern Shore, finding it could cut travel times from nearly 50 minutes by car to under 10 minutes for most residents. By mapping age, flood risk, and access barriers, the study highlights how targeted drone networks could improve health equity in rural, disaster-prone regions.

Teenagers who experienced higher COVID-19 stress during remote schooling were more likely to become open to trying vaping, which significantly increased their odds of using e-cigarettes and cannabis two years later. The study reveals that susceptibility, not immediate use, was the critical pathway linking early stress to later vaping behaviors.

Researchers analyzing over 2,100 adults from the MIDUS cohort found that individuals with higher cumulative social advantage, spanning community ties, family relationships, and religious support, showed slower biological aging and lower systemic inflammation. The findings suggest that long-term social resources may become biologically embedded, influencing molecular pathways linked to longevity.

Although the home environment is known to influence behavior problems in children with developmental disabilities (DD), the precise contributions of specific domains remained unquantified, hindering targeted interventions.

New research confirms that ADHD (Attention Deficit Hyperactivity Disorder) can be linked to increased creativity and suggests that this creativity is associated with a greater tendency to let your mind wander.

Speech rhythm, a key attribute of natural languages that directly influences the effectiveness and efficiency of communication, is often compromised in people with neurodegenerative diseases such as Amyotrophic Lateral Sclerosis, or ALS.

Scientists have found that ADHD (Attention-Deficit/Hyperactivity Disorder) in women is diagnosed approximately 5 years later than in men, despite symptoms appearing at the same age.

A new Kinsey Institute study has found gaps in sex education can have lasting impacts throughout adulthood, including relationship struggles, lack of confidence, and reduced quality of life.

Michigan State University scientists have pinpointed the molecular "switch" that supercharges sperm for their final sprint to an egg - a breakthrough that could reshape infertility treatments and pave the way for safe, nonhormonal male contraceptives.

Women living close to federally designated Superfund sites are more likely to develop aggressive breast cancers - including the hard-to-treat triple-negative subtype - according to new studies from Sylvester Comprehensive Cancer Center, part of the University of Miami Miller School of Medicine.

In a secondary analysis of a study of 200 classrooms, Mass General Brigham researchers found respiratory viral exposures were still high in those with HEPA purifiers, suggesting additional interventions are needed.

A new research paper was published in Volume 12 of Oncoscience on September 30, 2025, titled "Lifestyle and hormonal factors affecting semen quality and sperm DNA integrity: A cross-sectional study."

Liver fibrosis, a progressive scarring of the liver tissue, represents a major global health burden with limited treatment options.

UVA Health lung researchers are developing a promising approach to detecting patients at risk of interstitial lung disease (ILD), an increasingly common condition that is a leading reason for lung transplants.

New research has discovered that briefly altering how we perceive our own body can help unlock autobiographical memories – potentially even those from the early stages of childhood.

Respiratory viral diseases pose severe threats to animal health and global food security, especially in intensive pig farming systems.

Chikungunya is a vector-borne disease that affects both adults and children. While global efforts are ongoing to tackle chikungunya in adults, progress in addressing pediatric chikungunya remains inadequate.
