• Boy discovers microbe that eats plastic. It's not your average science fair when the 16-year-old winner manages to solve a global waste crisis. But such was the case at last month's Canadian Science Fair in Waterloo, Ontario, where Daniel Burd, a high school student at Waterloo Collegiate Institute, presented his research on microorganisms that can rapidly biodegrade plastic.

• EPA Thinks Twice About Recycled Tire Playground Surfaces. EPA scientists have cited gaps in scientific evidence, despite reviews showing little or no health concern, and are urging their superiors to conduct a broader health study. Under examination: concerns about children touching, swallowing or inhaling toxins including lead, metals, benzene, zinc and breathable particles from tire crumb and synthetic materials used in playgrounds and playplaces.

This is the first study to link phthalates to neurological development effects in humans. Previous health studies have linked phthalates to obesity, diabetes risk and poor sperm quality.
