  • Why does all the rap and hip hop coming out of South Los Angeles sound the same 20 years later? It may be because the quality of life there has not gotten any better in the past two decades [Radio.com]
  • The mayor's announcement was the culmination of a campaign promise to make the city more livable for poor and middle-class New Yorkers, many of whom find it increasingly difficult to pay their rent. He has pinned his housing plan on the goal of creating or maintaining 200,000 affordable units over the next 10 years—80,000 new units and 120,000 existing ones preserved—which would surpass the considerable investment in affordable housing over Mayor Bloomberg's three terms."

  • "The NeuroSky device we were using in Dumbo takes readings of the brain's electrical activity as it is transmitted to the body's surface—specifically, in this case, the forehead. An algorithm then takes those readings of beta, theta, delta, and other waves, and summarizes them into two general states—attentive and meditative. The idea behind the visualization will be to 'spray' this data onto a 3D map of the neighborhood we walked around and see what it reveals about the mental state of the experiment's participants as they moved through space." A new device hopes to measure the brain's reaction to the urban environment [Atlantic Cities]
