Long-term air pollution exposure raises motor neuron disease risk

Long-term exposure to ambient air pollution was associated with a higher risk of developing motor neuron disease and poorer prognosis after diagnosis in a large nationwide Swedish study. Higher particulate matter and nitrogen dioxide exposure were also linked to faster functional decline and increased likelihood of invasive ventilation.

Shingles vaccination is linked to slower biological aging in older adults

This population-based study of U.S. adults aged 70 and older found that shingles vaccination was associated with slower epigenetic and transcriptomic aging, as well as lower systemic inflammation. No significant associations were observed for neurodegeneration or cardiovascular biomarkers, highlighting domain-specific molecular effects rather than broad clinical changes.

Blood lipid–hormone ratios predict future asthma attacks years in advance

This study shows that specific ratios of circulating sphingolipids to steroids can predict the risk of future asthma exacerbations over five years with high discriminatory performance. By integrating metabolomics with longitudinal medical records, the research highlights lipid–hormone pathway imbalance as a key driver of asthma instability.

Adding lean pork to a plant-forward diet supports healthy aging biomarkers

A randomized crossover feeding trial in adults aged 65 years or older found that plant-forward diets incorporating either minimally processed lean pork or lentils produced similar short-term improvements in cardiometabolic and neuroactive biomarkers. Both diets supported metabolic health and functional stability, with no overall adverse biomarker effects attributable to including minimally processed red meat within a Dietary Guidelines–aligned pattern.

Ashwagandha aids recovery without blunting training stress in athletes

Six weeks of Ashwagandha root extract supplementation in semi-professional team-sport athletes was associated with sex-specific effects during pre-season training. Females showed improved perceived recovery with stable cortisol, while males demonstrated gains in lower-body power with stable cortisone levels.
