New evidence shows that clinician‑specified lifestyle protocols can deliver clinical‑grade outcomes, with structured exercise matching therapy for depression and weekly activity halving arrhythmia recurrence. Parallel neuroscience findings link a common anti‑seizure medicine to blocked amyloid‑beta formation and sustained reading and writing to nearly 40% lower dementia risk, while timing‑based approaches for ADHD and genetic insights into vaccine clotting refine how risk is managed.
- •Weekly 90 minutes of moderate exercise halves atrial fibrillation recurrence in post‑ablation patients
- •Structured physical activity performs on par with therapy or medication for depression and anxiety, especially when social and supervised

New analyses highlight preventable cancer burdens, stable fertility after COVID-19 vaccination, and escalating political polarization. The findings reinforce a shift from individual blame to system-level standards, with implications for nutrition policy, environmental safety, and mental health.
- •A global analysis estimates that more than one-third of cancer cases are preventable, with low public awareness of alcohol's cancer risk.
- •A large Swedish cohort finds that COVID-19 vaccination does not affect fertility.

New findings track how stress, timing, and social norms steer choices, from dating trust to crime risk. Concurrent advances in bioengineering and neurodegeneration point to scalable production of plant compounds and a decoy peptide strategy in Parkinson's, underscoring a shift from discovery to deployable tools.
- •Alcohol consumption shows a J-shaped heart-failure risk rising beyond roughly four drinks daily.
- •A single alcoholic drink fragments brain network communication in the short term.
