Digestate is a widely-used liquid alternative to mineral fertiliser, but nutrients readily leech from it, limiting its application. Here, the authors use a porous silicon material to enhance digestate, improving nutrient retention and crop yields.

The global food system faces mounting pressures from climate change, resource competition, conflict, and markets, with the harshest impacts falling on nutritionally vulnerable populations. Meeting this challenge demands a paradigm shift in how food is grown and distributed, supported by new science, policy reforms, and broad transformations from farm to fork.

This article examines the association between dietary protein diversity and frailty risk in older Chinese adults. The key findings are: 1. Higher protein diversity was linked to lower frailty risk, with each 1-unit PDS increase reducing risk by 10%. 2. Consistently maintaining a high PDS over 4 years was associated with the lowest frailty odds.
