The Nine Network Arts Series Also Explores the Threat to the White Sturgeon

St. Louis, MO — August 3, 2015 — The next episode of the Nine Network’s weekly science series, Science Matters, follows up on a risky investigation of the Gateway Arch’s stains. After building inspectors rappelled up and down the Arch last fall, extensive lab analyses have finally answered questions about the Arch’s exterior stains. This episode of Science Matters airs Wednesday, August 5 at 10:00 p.m. on Nine PBS. (All Science Matters episodes are rebroadcast Sundays at 10:30 a.m. and the following Wednesday at 10:30 p.m.)

Next, Science Matters follows the efforts of scientists working to fight an aggressive disease that is decimating the population of one of nature’s important species: the bat. Also on this episode, teachers are developing innovative methods to enhance learning retention in an effort to boost American students’ below-average math scores.

Finally, Science Matters looks at the continent’s largest freshwater fish, the white sturgeon, and how poachers in pursuit of their eggs for caviar are threatening the species’ survival.

Science Matters is a weekly series presented by the Nine Network of Public Media. Nine’s St. Louis science segments are also shown on PBS stations in cities nationwide. Science is one of the Nine Network’s primary focus areas. Science Matters programs can be viewed online after broadcast at
