After declining for 15 years, the number of people who don’t have enough to eat – some 815 million people, or 11 percent of the global population – rose in 2016, according to a recent United Nations report. The main culprits were climate change and armed conflict, explains agriculture researcher Leah Samberg, who also spotlights a solution: providing more resources for small-scale farmers in rural areas.
Pundits differ on how to interpret Trump’s approach to the Iranian nuclear deal. But Nancy Gallagher, director of the Center for International and Security Studies at the University of Maryland, shares public opinion data from on the ground in Iran that shows all of these interpretations “rest more on wishful thinking than a solid understanding of politics in Iran.”
And computer scientist Seth Copen Goldstein looks at the idea behind a forthcoming congressional proposal to combat “fake news” – based on lessons dating back to the presidential campaign of 1840.
