Community brain health programs successfully improve attention in older adults

As aging populations drive rising global healthcare demands, finding scalable ways to prevent cognitive decline has become a vital public health priority.

Most oncology AI research overlooks critical patient safety and privacy

Flinders University researchers were part of an international team that conducted a scoping review that identified 2,441 records and found just 32 studies examined how cancer patients, survivors and carers feel towards generative AI being used in their care.

What your gut microbes may have to do with how your brain ages

This review examines how diet-driven changes in the gut microbiota and microbial metabolites may influence cognitive aging through immune, metabolic, neural, endocrine, and barrier-related pathways. It highlights SCFAs, tryptophan-derived metabolites, and bile acids as key signaling mediators while emphasizing that much of the mechanistic evidence remains preclinical and human evidence is largely associative.

The obesity-microbiome story is more complicated than ‘good’ and ‘bad’ bacteria

This review finds that obesity is linked to reciprocal interactions between diet, the gut microbiome, microbial metabolites, and host metabolic pathways that influence appetite, insulin sensitivity, inflammation, and energy balance across the lifespan. It highlights diet as a particularly tractable way to influence this system, while emphasizing that microbiome changes associated with GLP-1 therapies remain difficult to separate from weight loss and that functional multi-omics approaches may help enable more personalized interventions.

Coffee, tea and dementia risk: Why the amount you drink could matter

A targeted perspective synthesizes epidemiological and mechanistic evidence examining how caffeine consumption during midlife may influence dementia risk later in life. The authors highlight potential roles for dose, age, CYP1A2 genotype, adenosine signaling and cultural drinking practices, while stressing that current observational evidence cannot establish causality.

Increasing Canadian wildfires jeopardize critical care for dialysis patients

In the midst of another intense wildfire season, a new study sheds light on the risks they pose to life-sustaining dialysis care for thousands of Canadians.

Bright light therapy boosts activity and sleep in older adults

Bright light therapy lamps can improve sleep, activity levels and circadian rhythms of older adults in urban areas who have diminished exposure to natural light, a new study from the University of Surrey reports.

AI learned from cardiologists’ notes, and needed far less labeled ECG data

By teaching an AI system to connect raw heart signals with the clinical insights contained in cardiologists’ reports, researchers tested whether routine ECGs could reveal more with far fewer labeled examples.

Two scientists win Horwitz Prize for Rett syndrome breakthrough

Columbia University will award the 2026 Louisa Gross Horwitz Prize to Adrian Bird and Huda Zoghbi for their pioneering work on epigenetic regulation in the nervous system and its role in human neurological disease, particularly Rett syndrome.

Plant-based fats improve long-term survival for prostate cancer patients

Men diagnosed with nonmetastatic prostate cancer can generally expect to live for many years after their diagnosis. However, cardiovascular disease and other cancers remain important threats to their long-term health.

Healthy ageing shaped by more varied biology than previously thought

Molecular changes of ageing are far more unique than previously thought, meaning two healthy individuals of identical age can experience significantly different ageing journeys.

Europe has a new mosquito problem, but it may not be the one you think

A scoping review of 91 studies, combined with a workshop involving 41 experts from six European countries, mapped the spread, biology, surveillance challenges, and potential disease relevance of the invasive mosquito Aedes koreicus. The researchers identified major gaps in species identification, vector competence, ecology, genetics, and long-term surveillance that must be addressed as the cold-tolerant mosquito expands across Europe.

Alcohol-related liver cancer deaths were falling. Then the trend reversed during the COVID-19 pandemic

A global analysis of GBD 2023 data found that alcohol-attributable liver cancer mortality increased modestly from 1990 to 2023, while mortality from alcohol-attributable cirrhosis, alcoholic cardiomyopathy, and alcohol use disorders declined. Liver cancer mortality shifted from a pre-pandemic decline to an increase during 2020–2023, particularly among women, although the researchers cautioned that the ecological analysis cannot establish that pandemic-related changes caused the reversal.

The global toll of snakebite may be much bigger than we thought

A global literature review and geostatistical modeling study estimated the burden of snake envenoming and deaths across countries, accounting for differences in surveillance, underreporting, socioeconomic conditions, and environmental factors. The analysis highlights major gaps in epidemiological data and provides updated country- and regional-level estimates to help guide prevention, antivenom access, surveillance, and healthcare resources.

Researchers found one childhood behavior linked to folic acid use before pregnancy

Researchers analyzed 646 children aged 2–8 years and their 563 mothers to examine whether maternal folic acid supplementation before conception was associated with childhood behavioral difficulties. Preconception supplementation was associated with a 34% lower risk of peer relationship problems, while no significant associations were found for total behavioral difficulties, emotional, conduct, hyperactivity/inattention, or prosocial problems.

Semaglutide did more than cut weight in this analysis of 6,239 adults

A systematic review and meta-analysis of nine randomized controlled trials involving 6,239 adults with overweight or obesity without diabetes found that subcutaneous semaglutide produced substantially greater reductions in body weight, waist circumference, and C-reactive protein than placebo. The higher dose of 7.2 mg semaglutide showed potential for greater weight loss, although the evidence is largely based on a single trial and requires confirmation.
