This week, the United Nations is hosting its first ever high-level meeting to tackle non-communicable diseases, such as heart and lung disease, cancer and diabetes. Dr. Judith Mackay, an expert on international health policy who Time named one of the most influential people in the world, is attending the talks. She tells us what governments can do to give their citizens a better chance at life-long health. Also, the struggle to control Congo's natural resources, which include minerals needed to make laptop computers, MP3 players and countless other electronic devices, has fueled the world's deadliest conflict since World War II. We speak with Aaron Hall, a policy analyst with The Enough Project, about efforts to make the mineral supply chains in Congo transparent.
