Roots Music... Sunscreened Reefs... Medicaid Waste... Nuclear in Virginia

Step onto (or into) the Front Porch Roots Music School with WMRA's Emily Richardson-Lorente....  Jessie Knadler has the lowdown on the shady side of sunscreen -- it may be killing the world's coral reefs, according to a study from a Virginia lab.... Virginia Public Radio has the report on waste in the state's Medicaid benefits, and on Dominion's vision for the future of power in Virginia, and how it may rely on more nuclear power.... and we go way out into the universe, and way back in time to the Big Bang, with Our Island Universe.
