CONCLUSIONS: Structural and functional muscle indicators showed divergent age-related patterns among rural community-dwelling women. The performance-based 5×STS demonstrated substantially greater relative differences than structural indicators, supporting the inclusion of functional assessments alongside structural measures for age-stratified evaluation in rural settings.

Fish oil supplements successfully delivered omega-3s to the brain, but a two-year study found no meaningful benefits for memory, cognition, or Alzheimer’s-related brain changes. The results challenge the idea that fish oil pills can help prevent Alzheimer’s and shift attention toward overall diet and lifestyle instead.

Government shutdown, staff shortages have complicated effort to meet 30 September deadline to spend funds

Scientists have uncovered a surprising clue that may help explain why multiple sclerosis (MS) progresses rapidly in some people but not others. In brain tissue from patients with severe MS, researchers found large numbers of “foamy” immune cells packed with fat droplets after absorbing damaged myelin. These overloaded cells appear to switch from helping repair the brain to fueling ongoing damage and inflammation.

About 1 million insect species have been described, but a new analysis suggests tens of millions more may be out there

The unconscious brain appears to be far more capable than scientists once believed. Researchers found that patients under general anesthesia could still process language at a sophisticated level, distinguishing nouns, verbs, and adjectives while listening to stories. Even more remarkably, neural activity showed signs of predicting upcoming words before they were heard. The results challenge traditional ideas about consciousness and hint at new possibilities for brain-computer interfaces.

A six-month study of more than 120 adults in their 70s found that high-intensity interval training (HIIT) may offer a key advantage over other forms of exercise: it helped reduce body fat while preserving valuable muscle mass. While moderate and low-intensity workouts also led to some fat loss, only HIIT maintained lean muscle, which becomes increasingly important with age.

Scientists at UCLA have linked long-term exposure to the pesticide chlorpyrifos with a sharply increased risk of Parkinson’s disease. People exposed to the chemical near their homes were more than twice as likely to develop the condition. Laboratory studies showed that chlorpyrifos damages dopamine neurons and interferes with the brain’s ability to remove toxic protein buildup.

Anti-aging pharmacology has transitioned from early exploratory lifespan-extension studies to a hallmark-informed, multi-level framework that integrates mechanistic, preclinical, and translational evidence. Using a bibliometric-guided, strategy-oriented approach, this review maps the explicit anti-aging drug literature from 2005 to 2025, identifies historically influential compounds, and evaluates their translational readiness. The field converges on three partially overlapping intervention...

CONCLUSIONS: The findings from our study indicate that supporting the psychological and spiritual resources of older adults plays an important role in strengthening the successful aging process. Longitudinal studies on successful aging are recommended.
