Oxidative Stress is a condition in which antioxidant levels are lower than normal. Antioxidant levels are usually measured in blood plasma.

Alcohol consumption in early adulthood linked to middle age cognitive decline

It's well known that alcohol consumption is an age-old method for coping with stress. But surprising? research led by the University of Massachusetts Amherst found that, when such self-medication begins in early adulthood, negative cognitive effects start to show up in middle-age-even after long periods of total abstinence.

Air pollution may be lowering global IQ and widening inequality, researchers warn

Researchers argue that exposure to fine particulate air pollution (PM2.5) may affect cognitive function and intelligence, potentially causing large population-level losses in global IQ. Using modelling based on published exposure–response data, the authors estimate that pollution could be associated with tens of billions of IQ points lost worldwide, with the largest impacts in lower-income regions.

How social and environmental exposures across life influence mental health risk

Researchers outline how the exposome framework, which captures the totality of environmental exposures across the lifespan, can help explain how non-genetic factors shape mental health risk and resilience. The perspective highlights how integrating environmental, biological, and social data could improve prevention strategies, research models, and personalized mental health care.

Dual targeting strategy may improve treatment for resistant lung cancers

Findings from a study led by researchers at The Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James) support the potential of new therapies that could improve clinical outcomes for patients with squamous and adenocarcinoma non-small cell lung cancers (NSCLC) that don't respond to immunotherapy.

Why measles remains one of the most contagious viral diseases worldwide

This review synthesizes current evidence on measles virus biology, immune responses, complications, treatments, and prevention strategies. It highlights how measles can suppress immune memory, increasing susceptibility to other infections, and underscores vaccination as the most effective control measure.

How zinc deficiency could worsen heart inflammation and what that means for patients

This review examines how zinc regulates inflammatory and redox signaling pathways involved in myocarditis and pericarditis, highlighting mechanisms such as NF-κB inhibition and the redox zinc switch. The authors conclude that maintaining optimal zinc status may support cardiovascular resilience, while emphasizing that clinical translation requires further targeted trials.

Pomegranate’s hidden fiber-bound polyphenols significantly increase total antioxidant capacity

Researchers showed that pomegranate fruit extract contains substantial levels of non-extractable polyphenols bound within its fibre-rich matrix, significantly increasing its total measured antioxidant capacity. In human neuronal and astrocytic cell lines, the extract reduced hydrogen peroxide–induced oxidative stress, particularly in astrocytes, under in vitro conditions.

Swiss centenarians show youthful blood protein profiles in aging study

In Switzerland, 0.02% of the population lives beyond the age of 100. Could there be biological characteristics associated with this exceptional longevity? As part of the "SWISS100" study, the first large-scale Swiss research project dedicated to centenarians, a team from the University of Geneva (UNIGE) and the University of Lausanne (UNIL) compared the blood profiles of centenarians with those of octogenarians, and then with those of individuals aged 30 to 60.

New review explores whether berries can slow cognitive decline linked to obesity

This systematic review in Nutrients evaluates human studies investigating whether polyphenol-rich berry consumption can modulate obesity-related metabolic dysfunction and support cognitive performance, particularly in individuals at risk of mild cognitive impairment. Evidence suggests modest memory benefits and possible metabolic improvements, although biomarker findings and long-term clinical relevance remain uncertain.
