Why in news?
The idea of the exposome—every environmental exposure a person experiences from conception onward—is gaining momentum. In 2025 a Global Exposome Moonshot project was launched to map human exposures, and 2026 has seen new partnerships and regional initiatives. Scientists and policymakers believe exposome research can help prevent diseases and improve public health.
Background
The exposome concept complements the genome. While genes contribute 10–20% to disease risk, environmental exposures such as pollutants, diet and lifestyle account for up to 80%. The Global Exposome Moonshot, backed by UNESCO and national governments, aims to create the first comprehensive atlas of exposures. The initiative encourages collaboration across countries and disciplines.
Key developments
- The Moonshot launched in May 2025 with a vision to build a global network of exposome research hubs. Scientists collect data from wearable sensors, health records, and citizen science projects to chart exposures over a person’s life.
- In 2026 the initiative expanded into Africa through a Pan‑African Network on Exposomes for Health and Development. This network brings together researchers and policymakers from across the continent to address local environmental challenges.
- Partnerships with organisations such as the International Network for Government Science Advice (INGSA) and UNESCO promote knowledge exchange, policy advice and capacity-building. Community participation ensures that local populations have a say in research priorities.
- Regular meetings and workshops bring together scientists, health professionals and activists to discuss emerging data, ethical issues and strategies for translating research into preventive measures.
Why it matters
Mapping the exposome could revolutionise public health by identifying environmental triggers of diseases ranging from asthma and cancer to mental illness. By understanding exposure pathways, policymakers can design targeted interventions, such as reducing pollution or improving nutrition. The Moonshot also aims to strengthen health equity by involving communities, especially in low‑ and middle‑income countries, in co‑creating solutions.
