Genetic study reveals immune-related roots of allergic conjunctivitis

Allergic conjunctivitis is one of the most common eye conditions. A new large-scale genetic study shows that susceptibility to the disease is strongly linked to genes that regulate inflammation and immune defense.

Lifetime alcohol consumption associated with higher risk of colorectal cancer

Studies have demonstrated a link between alcohol consumption and an elevated risk of colorectal cancer. New research now reveals that higher lifetime alcohol consumption is also associated with a higher risk,

Olive oil type matters for cognition and gut health in older adults

Higher intake of virgin and total olive oil was associated with modest but significant improvements in cognitive performance over two years in older adults with metabolic syndrome. These associations were partly linked to gut microbiota composition, with specific taxa such as Adlercreutzia contributing a small mediating effect.

Why exercise is essential for restoring fitness after GLP-1-based weight loss

This randomized controlled trial shows that structured moderate-to-vigorous exercise, alone or combined with liraglutide, improves physical function and cardiorespiratory fitness after diet-induced weight loss in adults with obesity. In contrast, liraglutide alone sustains weight loss but does not significantly improve measured physical fitness outcomes.

Tiny plastic particles may interfere with brain processes implicated in Parkinson’s disease

Micro- and nanoplastics are increasingly detected in human tissues, including the brain, and experimental evidence suggests they can interact with biological pathways central to Parkinson’s disease pathology. This review synthesises mechanistic data indicating that plastic particles may influence protein aggregation, neuroinflammation, mitochondrial dysfunction, and the gut–brain axis, while emphasising the need for prospective human studies.

Three daily servings of full-fat dairy do not worsen weight or blood markers

This randomized 12-week trial examined whether adding three daily servings of full-fat dairy to diets aligned with Canada’s Food Guide affects body weight, cardiometabolic markers, and nutrient intake in adults with overweight or obesity. Full-fat dairy intake did not adversely affect weight, body composition, or metabolic health and increased calcium and protein intake, supporting dietary compatibility rather than therapeutic benefit.

Secondary-treated wastewater still transfers antibiotic resistance to fresh produce

A study reveals tertiary-treated wastewater significantly reduces antimicrobial resistance risks in lettuce irrigation compared to secondary-treated water.

More iron, less damage: why chronic lung infections persist

Research shows that iron-rich conditions boost Pseudomonas aeruginosa growth and biofilm formation, yet reduce virulence, complicating chronic lung infections.

New role for GLP-1 drugs: Improving survival in people with severe psychiatric disorders

This editorial argues that GLP-1 receptor agonists could substantially improve healthspan and reduce premature mortality in people with serious mental illnesses by targeting cardiometabolic risk rather than psychiatric symptoms alone. It highlights emerging evidence, safety considerations, and equity challenges that position GLP-1 RAs as a promising public health strategy for this high-risk population.

Evidence links gut microbiome changes to Alzheimer’s progression

Human studies consistently report gut microbiome differences in mild cognitive impairment and Alzheimer’s disease, but findings vary widely by cohort, methods, and taxa. Heterogeneity and limited longitudinal data prevent causal inference, highlighting the need for functional profiling and well-designed intervention trials.

Why the age you start smoking matters as much as how much you smoke

Starting smoking at a younger age is associated with substantially higher risks of myocardial infarction, stroke, and death, even after accounting for cumulative smoking exposure. Early initiation also amplifies the cardiovascular harm of heavier smoking, indicating increased vulnerability when smoking begins in adolescence.

The long and short of it: Human penis size evolved for both attraction and rivalry, study suggests

This experimental study used life-sized and screen-based 3D male avatars to test how penis size, height, and body shape influence female mate choice and male assessments of rivals. The findings show non-linear female preferences for size and demonstrate that penis size functions as a modest but significant cue in male perceptions of fighting ability, alongside stronger traits such as height and torso shape.

Large multi-ancestry study expands understanding of schizophrenia genetics

A landmark study led by researchers with the Department of Veterans Affairs has uncovered new genetic insights into schizophrenia by analyzing data from ancestrally diverse populations, including African Americans, through the Million Veteran Program (MVP) and Cooperative Studies Program (CSP).

PTPN2 gene protects the gut from harmful bacteria driving inflammatory bowel disease

Two recent studies from the University of California, Riverside, published in the same issue of Gut Microbes highlight the role of a gene called PTPN2 in protecting the gut from harmful bacteria linked to inflammatory bowel disease (IBD).
