After recent changes to Elon Musk’s X, a gradual migration turns into a stampede

Commensal bacteria and their derivatives hold significant promise as therapeutic interventions to delay aging. However, with the diverse nature of the soil microbiome and the long lifespan of mammalian models, the exploration of the influence of soil bacteria and bacteria-derived molecules on host aging remains limited. We conducted a lifespan screening in Caenorhabditis elegans using plant root bacterial collection. Our screening identified 8 genera of bacterial isolates capable of extending...

The interest in the Mediterranean diet has grown considerably due to its potential health benefits on the prevention of diverse age-related chronic diseases and its association with longevity. This dietary pattern, considered among the healthiest in the world, is not simply a combination of healthy foods but goes further in its historical and cultural roots. Mediterranean diet is not intrinsically tied to any specific religion or spiritual system, but its cultural and geographical context has...

Observers fear next administration will loosen environmental regulations, downplay role of science

Disease-modifying therapies for Alzheimer's disease (AD) are likely to be most beneficial when initiated in the presymptomatic phase. To track the benefit of such interventions, fluid biomarkers are of great importance, with neurofilament light chain protein (NfL) showing promise for monitoring neurodegeneration and predicting cognitive outcomes. Here, we update and complement previous findings from the Dominantly Inherited Alzheimer Network Observational Study by using matched cross-sectional...

CONCLUSIONS AND IMPLICATIONS: The findings reveal the heterogeneity of frailty among community-dwelling Japanese older adults, with a high prevalence of cognitive impairment risk. The subgroup with risk of cognitive, physical, and functional decline had the highest mortality risk, highlighting the need for multidimensional assessment and intervention.
