Energy Dept abandons key step in nuclear waste vitrification plan
After 16 years of tests the Energy Department drops a critical separation step at Savannah River in South Carolina. Secretary Bill Richardson will hire a private contractor to explore alternatives to the failed process that produced explosive gases. The plan to vitrify waste into 6,000 glass logs could cost over 17 billion dollars and take about 30 years. A GAO study estimates a substitute method may take 8 to 10 years and cost 1 to 3.5 billion.

Drug may allow mismatched bone marrow donors
A new immune suppressing drug targets only the problematic immune response, enabling bone marrow transplants from poorly matched donors. Reported in the New England Journal of Medicine, early trials on terminally ill cancer patients show promise and potential extension to hearts, kidneys, and other organs. Dr Eva Guinan of Dana-Farber Cancer Institute notes this could broaden transplant feasibility by reducing strict matching requirements.
