This article explores the multifaceted impacts of AI on society, focusing on its environmental, economic, labour, ethical and social implications. AI offers transformative benefits, enhancing efficiency, automating tasks and driving innovation across various sectors. However, its rapid adoption also presents significant challenges, including increased energy consumption, job displacement, economic inequality and ethical concerns related to bias and privacy.

Nutrition across the human lifespan has significant effects on health, not only through direct physiological pathways but also through epigenetic mechanisms that regulate gene expression without directly altering DNA sequences. This paper reviews how variations in micro- and macronutrient intake during critical developmental windows shape long-term health outcomes and disease risk in adulthood.

Trauma and environmental stressors leave biological marks that can shape mental health across an individual's lifespan. Through processes like DNA methylation, histone modification and non-coding RNAs, stress becomes “written” into gene regulation, increasing vulnerability to conditions such as PTSD and depression. This paper reviews evidence across different stages of life and highlights new avenues for treatment, including psychedelics and artificial intelligence.

Alzheimer’s Disease (AD) is the most common form of dementia that has symptoms of progressive cognitive decline linked to amyloid-β plaques, tau tangles and disrupted gene regulation. This paper explores the epigenetic landscape of AD and examines how music therapy can modulate these pathways.

Global climate diplomacy is commonly presented as a cooperative, science-driven enterprise, but its practice is shaped by profound structural and strategic power asymmetries. This paper discusses the compatibility between climate policies, institutions and the diplomatic actions of powerful states with the adaptive and strategic manoeuvring of less powerful states.
