Some food manufacturers could capture major nutrition and environmental gains by changing surprisingly few products

Researchers assessed the nutritional quality and environmental impacts of product portfolios from 44 major UK food and beverage manufacturers, covering 51.5% of the retail market. Their modelling showed that targeted changes to existing product lines could capture a substantial share of the potential nutrition and environmental gains for some manufacturers, although broader food-system changes would still be required to meet national and societal targets.

Better fitness was linked to healthier brain structure, but not better memory

Researchers studying 353 cognitively unimpaired adults aged 60 to 94 found that higher muscular capacity was associated with lower basal ganglia perivascular space volume, while greater aerobic fitness was associated with greater gray matter volume and medial temporal lobe thickness. Fitness was not directly associated with global cognition or episodic memory, and evidence for cognitive reserve was limited, although VO₂max explained additional variation in delayed verbal memory beyond tau burden.

Sex-specific biological clocks reveal how aging differs across the body in women and men

Researchers developed 38 sex-specific biological aging clocks across 15 organ systems, finding differences between females and males in genetic architecture, molecular signatures, disease associations, and mortality patterns. Brain aging clocks were linked to progression from mild cognitive impairment to Alzheimer’s disease in both sexes and to sex-dependent cognitive trajectories among solanezumab-treated A4 participants, while the authors stressed that sex-pooled and sex-interaction models remain complementary approaches.
