A few of the recent pieces I've liked:
Alana Semuels in The Atlantic: How Poor Single Moms Survive
Nina Martin of ProPublica interviews David Cohen: For Abortion Providers, a Constant Barrage of Personalized Harassment
Terry Fulmer at the Health Affairs Blog: Independence -- It's What Older People Want
Charles D. Ellison at The Root: Wake Up, Black People. The Supreme Court Is Poised to Drop a Bomb on You
Vanessa Heggie in The Guardian: World AIDS Day: How AIDS activists changed medical research (also, it's not a new publication, but World AIDS Day was a good opportunity to re-read this excerpt from Maryn McKenna's book Beating Back the Devil).
