Advances at the intersection of microbiology and materials are strengthening cancer immunotherapy, while gut-brain findings are reframing mental health care. Social-science analyses challenge assumptions about online toxicity and policy narratives, and a negative Alzheimer's antiviral trial reinforces the importance of publishing corrective evidence.

New findings converge on a systems-first approach: precision prevention, equitable access, and shared infrastructure deliver better outcomes than catchy narratives. From projected mass mortality linked to wildfire smoke to genotype-guided aspirin benefits and targeted cognitive training, the evidence prioritizes design, access, and specificity over slogans.
