Pediatric leukemia is a cancer of the blood and bone marrow. There are about 3,000 new cases in the United States every year, typically in children between the ages of four and six.

With treatment, about three-quarters of affected children are able to beat the disease.

But for those with what’s known as “high risk” leukemia, the odds of survival are much worse.

Washington University pediatric oncologist Dr. Todd Druley has been trying to use genetics to understand why some leukemia is so hard to treat. He spoke with St. Louis Public Radio's Véronique LaCapra.

The National Science Foundation has awarded a local researcher $1.3 million to study the genetics of how corn plants take up nutrients.

The ultimate goal is to reduce the amount of fertilizer needed to grow the ubiquitous crop.

Ivan Baxter, a U.S. Department of Agriculture research scientist and assistant member at the Donald Danforth Plant Science Center, will lead the research.
