A few of the recent pieces I've liked:
David Leonhardt in the New York Times: In Climbing Income Ladder, Location Matters
Jim Morris at the Center for Public Integrity: Industry muscle targets federal 'Report on Carcinogens'
Stephanie Lee in the San Francisco Chronicle/ Reporting on Health: Poverty, health struggles in scenic Mendocino
Charles Kenny & Justin Sandefur in Foreign Policy: Can Silicon Valley Save the World? ("Defeating global poverty is the latest start-up trend. But is there really an app for that?")
