U of M official watching stem cell debate closely

One of the controversial issues in this year's presidential campaign is stem cell research. While both President George W. Bush and his Democratic challenger Sen. John Kerry favor research on adult stem cells, they have very different positions on embryonic stem cell research. In August of 2001, Bush decided to restrict public funding for research on embryonic stem cells to already existing cell lines. Kerry has said that, as president, he would reverse those restrictions. Embryonic stem cells are capable of becoming almost any type of cell or tissue in the body, which makes them valuable in the search for medical treatments. But the research also raises ethical questions, and many opponents say it destroys human life. The University of Minnesota's Stem Cell Research Institute is a leader in the field. Morning Edition host Cathy Wurzer spoke with Catherine Verfaillie, director of the Institute.

Education policy meets neuroscience

Dr. Jack Shonkoff, a pediatrician and Dean at Brandeis University, says you can learn a lot about effective education policy by looking at the human brain and how it works. According to Shonkoff, neuroscience proves that emotional, social and verbal development don't happen independently in the brain; they're all interconnected, hence education reform has to address problems with schools, teachers, parents and communities. He spoke this summer to the Minnesota School Readiness Business Advisory Council, a group of local business leaders working on issues of early childhood development.
