The newest podcast from the Wilson Center’s Project on Emerging Nanotechnologies highlights how engineers are using nanotechnology to develop more efficient and cost-effective ways to desalinate seawater and purify wastewater. In the future, these new water purification technologies could be adapted for use in poor countries where access to safe water is limited. The podcast is the third in the “Trips to the Nano Frontier” series, which also includes podcasts on green nanotechnology and nanomedicine. The full series is available online.

The Center’s Environmental Change and Security Program (ECSP) also produces an original podcast series. ECSP’s podcasts, which feature interviews with leading scholars and practitioners, have examined the role of gender in population, health, and environment programs; the challenges and opportunities presented by urban population growth; and the link between international trade and aid policies and conflict.
