Five epigenetic clocks reveal shared and distinct signals of aging

Researchers linked five epigenetic clocks to distinct blood gene-expression patterns and biological pathways in 3,227 Health and Retirement Study participants. TAGS derived from these patterns often showed stronger associations with frailty, functional measures, morbidity, and mortality than their parent clocks, although further validation is needed.

Human experts remain essential for checking clinical AI outputs

In a Rwanda-based evaluation, LLM judges produced consistent and far cheaper ratings of clinical AI responses but matched local clinician ratings on only a minority of assessment criteria. They consistently missed potential demographic bias, indicating that human expert evaluation remains important despite AI’s potential role in initial screening.

Air pollution mixtures linked to higher early preterm birth risk

Pregnancy puts higher oxygen demands on the body, so expectant mothers breathe significantly more air over the course of a day. When air quality is bad, they're also breathing in more harmful pollutants.

Adverse pregnancy outcomes increase future peripheral artery disease risk

Women who experience pregnancy complications such as gestational diabetes, preeclampsia, or preterm delivery have a significantly increased long-term risk of developing peripheral artery disease (PAD) later in life, according to a new study published July 21st in the open access journal PLOS Medicine by Casey Crump of the University of Texas, US, and colleagues.

Dementia addiction and psychiatric disorders show distinct patterns of accelerated brain aging

People with dementia, mild cognitive impairment, alcohol addiction, or psychiatric disorders such as schizophrenia show increased brain aging, each in specific patterns within the brain, according to a study published July 21st in the open access journal PLOS Medicine by Shile Qi from the Nanjing University of Aeronautics and Astronautics, China, and colleagues.

Moderate coffee intake may support heart health, AHA says

The American Heart Association finds that habitual coffee consumption is associated with lower risks of several cardiovascular outcomes, although most evidence comes from observational studies. Moderate intake is generally safe for most adults, while energy drinks and individual caffeine sensitivity may increase cardiovascular concerns.

Childhood ultra-processed food intake associates with altered insulin responses

Researchers analyzed dietary and metabolic data from 508 nondiabetic Mexican American children in the SAFARI family cohort, finding that higher ultra-processed food scores were associated with lower insulin sensitivity and altered early insulin secretion measures. The exploratory cross-sectional study did not establish causality, and its multiple comparisons, historical dietary data, and questionnaire-based UPF estimates warrant confirmation in longitudinal studies and trials.

Less sitting in pregnancy is linked to fewer adverse outcomes

A JAMA cohort study of 470 pregnant women found that lower sedentary time, higher light-intensity activity, and more daily steps across pregnancy were associated with fewer adverse pregnancy outcomes. The findings support testing practical “sit less, move more” interventions, but cannot establish cause and effect.
