Scientists found a link between Mediterranean diet blood markers and longer survival

Researchers found that a previously validated 67-metabolite blood signature of Mediterranean diet adherence was associated with lower long-term mortality across a Spanish trial population and three US cohorts. Participants with the highest signature scores had a 23% lower relative hazard of death than those with the lowest scores in both populations, although the findings do not establish a causal relationship.

Coffee, citrus and genetics: What scientists found inside human breast milk

In a bioRxiv preprint, researchers analyzed 458 metabolites in breast milk samples from 349 mothers to investigate how maternal diet, genetics, clinical characteristics, and milk-cell gene expression relate to milk composition. Maternal diet explained the greatest share of metabolite variation among the measured maternal factors, while specific genetic variants and gene-expression patterns were associated with individual metabolites, although the study did not establish effects on infant health.

New fluorescent paper strips make vitamin B12 testing simpler

Measuring vitamin B12 in food usually means bringing the sample to the laboratory. A new fluorescent sensor could help move part of that process onto something much simpler: a paper strip or cotton swab.

Common chemical exposures in pregnancy may be linked to early attention and memory

Researchers examined whether prenatal exposure to aromatic amines and cotinine was associated with attention, processing speed, and memory in 250 infants assessed at 7.5 months. The study found mixed patterns across cognitive measures, with several estimates suggesting poorer attention or memory but carrying substantial statistical uncertainty.

Older adults with higher polyphenol intake were less likely to have mild cognitive impairment

In a cross-sectional study of 92 older Italian memory-clinic patients, higher habitual intake of total dietary (poly)phenols and several specific subclasses was associated with a lower likelihood of mild cognitive impairment (MCI). Total (poly)phenol intake was not associated with cognitive test performance or circulating inflammatory biomarkers, and the authors cautioned that the small observational study cannot establish causality.

Researchers mine cobra toxins to uncover a membrane-disrupting antimicrobial peptide

Researchers combined toxin sequence mining with machine learning and deep-learning prediction tools to identify and experimentally test 14 antimicrobial peptide candidates derived from cobra cardiotoxins. Most candidates showed limited antibacterial potency, while CTX-p5 displayed moderate membrane-disrupting activity, revealing both the potential and current limitations of computationally guided venom peptide discovery.

Could scorpion venom inspire new treatments for liver disease?

Scorpion venom peptides show promising anti-inflammatory, antiviral, analgesic, and immunomodulatory effects, with experimental evidence suggesting that some candidates could target pathways involved in chronic liver disease and viral hepatitis. The review highlights Kv1.3-blocking peptides and antiviral compounds as potential therapeutic leads, while emphasizing that limited hepatic efficacy data, poor pharmacokinetics, immunogenicity, and manufacturing challenges must be overcome before clinical translation.

Could the type of fiber children eat matter for their developing gut microbiome?

A recent study found that different dietary fibers can shape the composition and activity of the gut microbiome during early childhood, with xyloglucan, arabinoxylan, and pectin increasing short-chain fatty acid production in laboratory fermentation experiments. Some fibers also supported gut barrier measures and altered inflammatory responses, while observational data linked higher pectin intake with greater microbial diversity in young children.

Early-life stress rewires brain epigenetics to heighten sensitivity to future stress

. Early-life stress increased SETD7 and H3K4me1 in the ventral tegmental area of mice, creating an epigenetically primed state that heightened later transcriptional, neuronal, and behavioral responses to stress. Reducing Setd7 during development lowered H3K4me1 and weakened these stress-sensitizing effects, identifying a mechanism that may help explain how early adversity leaves lasting biological effects.

A common dietary nutrient feeds a gut pathway linked to atrial fibrillation

Researchers linked higher plasma TMAO to prevalent atrial fibrillation in 5,090 people and found that TMAO or choline supplementation accelerated AF onset, progression, atrial remodeling, and electrical dysfunction in mice. Inhibiting gut microbial TMA production lowered circulating TMAO and delayed AF in mice, identifying a potential therapeutic pathway that now requires human testing.

Spermidine boosts key cellular processes linked to aging in early research

This review finds that spermidine supports autophagy, mitochondrial function, and healthspan in experimental models, while observational studies link higher dietary intake to lower mortality. However, human trials have produced limited and mixed results, leaving its clinical role in healthy aging unresolved.

Stuffed toys can release short-chain PFAS into saliva, study finds

Researchers tested 18 stuffed toys and found that all released at least one targeted PFAS into artificial saliva under mouthing-relevant conditions, with PFHxA driving much of the variation between products. Modeled intake of the four PFAS covered by EFSA’s group tolerable weekly intake remained below that benchmark, but some high-PFHxA toys had reduced margins of exposure, and water rinsing produced mixed results.
