Paul Smiths, NY, Nov 28, 2013 — In general, plants make food from sunlight, and animals fuel themselves by "burning" oxygen. But some animals think outside the box.
Curt stager and Martha Foley look at a photosynthetic slug that hijacks the genetic machinery of the algae in its diet, and at a jellyfish that needs no oxygen, burning the alternative fuels of hydrogen and sulphur. Go to full article

Paul Smiths, NY, Oct 18, 2012 — Not all evolutionary change is good. Genetic changes can be neutral or harmful, as well as beneficial. And some change can be both, conferring benefit when a single copy of a gene is present, and causing a life-threatening disease when copies are inherited from both parents. Martha Foley and Dr. Curt Stager roll the dice on evolution. Go to full article
Dec 08, 2003 — Genetic engineering, especially when it comes to food, is a battleground. On one side: people who fear a world of contaminated food, harming humans and the environment. The other side fears we'll miss an opportunity to prevent hunger and disease. Now there's a ground breaking initiative that might produce compromise. The Great Lakes Radio Consortium's Mary Stucky reports that some researchers think safety can be built into the bio tech industry. Go to full article
