Fighting a cold? A meal gives your immune cells an immediate boost
Experiments in humans and mice suggest that certain white blood cells, known as T-cells, may respond to infections more effectively after a meal. The research calls into question the notion of "starve a fever, feed a cold."

Immune surveillance and microbial escape in the aging host: Why does the microbiome lose its balance?

Host-associated microbiomes are stable across most of the lifespan, but what drives late-life deterioration remains unclear. This Unsolved Mystery proposes interventions that restore immune surveillance capacity alongside ecologically informed microbiome management.
