Aerobic exercise boosts executive function in postmenopausal women

Regular aerobic exercise – the kind that gets your heart pumping – can improve important thinking skills called executive functions, and the benefits appear especially strong for women after menopause, according to Rutgers researchers.

Multimorbidity linked to shorter lifespans in aging dogs

As dogs age, many develop more than one chronic health condition. New research from the Texas A&M College of Veterinary Medicine and Biomedical Sciences (VMBS) shows those conditions can dramatically shorten a dog's lifespan, highlighting the importance of managing multiple diseases together rather than individually.

UC San Diego researchers win DARPA award to develop improved red blood cells

Researchers at the University of California San Diego School of Medicine have been awarded a contract of up to $11.312 million from the Defense Advanced Research Projects Agency (DARPA) to pursue a high-risk, high-reward research project aimed at developing optimized red blood cells that can temporarily boost human performance and health.

Exercise intervention associated with reduced atrial fibrillation burden

An exercise program combining short-term supervision with long-term home-based exercise was associated with reduced atrial fibrillation burden and other meaningful benefits, according to results presented in a Hot Line session today at ESC Congress 2026.

People with diabetes may have another reason to protect their cardiovascular health

Better cardiovascular health, measured using Life’s Essential 8, was associated with a lower risk of mild cognitive impairment among people with diabetes after accounting for genetic susceptibility. Associations with dementia varied by genetic risk, while higher LE8 scores were also linked to greater gray matter volume and lower white matter hyperintensity volume.

Digital technologies reshape clinical research and public health

JMIR Publications this week released seven feature News and Perspectives articles covering how digital tools are transforming clinical research, public health readiness, health care institutions, and consumer choices.

New study links gestational age to malnutrition in cerebral palsy

Malnutrition is a common concern in children with cerebral palsy (CP), a condition that can affect movement, feeding, swallowing, and independence.

Blood-brain barrier-crossing blood pressure drugs linked to lower dementia risk

In a large Australian cohort of adults with hypertension, use of blood-brain barrier-crossing antihypertensive medications was associated with a lower risk of dementia and mortality than use of non-crossing drugs. The association was strongest for beta-blockers and angiotensin II receptor blockers, although the observational design means the findings cannot establish causality.

Men see traditional dieting as restrictive and female-focused, study finds

A new study has identified why many men struggle with weight loss, finding that traditional diet programmes are often perceived as too restrictive and primarily aimed at women.

Why living to 100 may depend on far more than diet and exercise

A critical narrative review found that healthy diets, regular physical activity, strong social ties, and psychological well-being can support healthier aging and reduce premature mortality, but none has been shown to reliably determine who reaches 100. The authors argue that exceptional longevity arises from complex interactions among biological resilience, genetics, social and environmental conditions, lifelong exposures, and chance rather than any universal lifestyle formula.

Scientists found a distinct gut microbiome pattern in people with symptomatic diverticular disease

A multicenter Japanese study found that symptomatic uncomplicated diverticular disease (SUDD) was associated with reduced gut microbial diversity, increased abundance of the Ruminococcus gnavus group, and depletion of Coprococcus and other butyrate-producing bacteria. Predictive microbiome analysis also identified enrichment of pathways linked to exopolysaccharide biosynthesis and the cell cycle, although the observational design means these associations cannot establish causality.

Researchers traced lifelong obesity resistance in mice back to an early microbial encounter

Natural wild-derived microbiota protected mice against diet-induced obesity across sexes, genetic backgrounds, and age by increasing energy expenditure and promoting a thermogenic program in brown adipose tissue. The effect depended on the immune system’s initial encounter with the microbiota and required CCR2-associated myeloid activity, revealing a long-lasting microbiota-immune-brown fat pathway.

Standard memory tests fail to detect post-chemotherapy brain fog

Standard memory tests such as word-pair or list-learning tests used in clinics may fail to detect the real-life memory problems reported by many female breast cancer survivors after chemotherapy.

Physical activity declines significantly with age despite good initial health

A recent study from the University of Jyväskylä, Finland, shows that physical activity declines substantially with age, even among older adults who are in good physical condition.

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.

Type 2 diabetes incidence increases 10-fold among American youth

Type 2 diabetes has traditionally been a disease that has developed mostly in middle-aged and older adults.

These simple fitness tests revealed which older adults had the lowest death risk

Objective fitness tests in 13,423 Taiwanese adults aged 65 years or older linked better balance, agility, lower-body strength, and cardiorespiratory fitness with lower all-cause mortality over a median seven years. A multidomain fitness index showed the strongest association, suggesting that simple performance tests may add useful information to conventional geriatric risk assessment.

A two-year diet trial challenges the idea that weight loss is the only result that matters

In the two-year DELISH randomized trial, adults with obesity achieved modest, sustained weight loss with either an adapted Mediterranean-style program or a commercial weight loss program. The Mediterranean-style intervention produced greater improvements in self-reported diet quality, while 24-month weight loss did not materially differ between groups.

UC Berkeley researchers find new potential treatment for obesity and diabetes

Over the past five years, medications called GLP-1s have revolutionized the treatment of metabolic disorders like obesity, diabetes and fatty liver diseases.
